Identification of the factor affecting learning curves of laparoscopic gastrectomy through the experience at a Japanese high-volume center over the last decade. Ann Gastroenterol Surg 2024; 8:604-610. [PMID: 38957566 PMCID: PMC11216783 DOI: 10.1002/ags3.12782] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/17/2023] [Revised: 11/19/2023] [Accepted: 02/06/2024] [Indexed: 07/04/2024] Open
Abstract
Background Though laparoscopic gastrectomy (LG) has become the gold standard for gastric cancer treatment according to the Japanese treatment guidelines, its learning curve remains steep. Decreasing numbers of surgeons and transitions in the work environment have changed LG training recently. We analyzed LG training over the last decade to identify factors affecting the learning curve. Study Design Laparoscopic distal and pylorus-preserving gastrectomies conducted between 2010 and 2020 were included. We assessed learning curves based on the standard operation time (SOT) defined by analysis of covariance. Then we divided the trainees into two groups based on the length of the learning curve and examined the factors affecting the learning curve with linear regression analysis. Results Among 2335 LGs, 960 cases treated by 27 trainees and 1301 cases treated by six attending surgeons were analyzed. The operation time was prolonged (p = 0.009) and postoperative morbidity rates were lower (p = 0.0003) for cases treated by trainees. Trainees experienced 38 (range, 9-81) cases as scopists and nine (range, 0-41) cases as first assistants to the first operator. The learning curve was approximately 30 cases. The SOT was calculated based on gender, body mass index, tumor location, reconstruction, and lymph node dissection. Trainees who had shorter learning curves had more experience (51-100 cases) with any laparoscopic surgery before LG training than the others (11-50 cases, p = 0.017). Conclusion Sufficient experience with laparoscopic surgery before starting LG training might contribute to the efficiency of LG training and shorten the learning curve.

Abstract
BACKGROUND Gastric cancer is one of the most common malignant tumors in the digestive system in China. Few comprehensive practice guidelines for early gastric cancer in China are currently available. Therefore, we created the Chinese national clinical practice guideline for the prevention, diagnosis, and treatment of early gastric cancer. METHODS This clinical practice guideline (CPG) was developed in accordance with the World Health Organization's recommended process and with the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) in assessing evidence quality. We used the Evidence to Decision framework to formulate clinical recommendations to minimize bias and increase transparency in the CPG development process. We used the Reporting Items for practice Guidelines in HealThcare (RIGHT) statement and the Appraisal of Guidelines for Research and Evaluation II (AGREE II) as reporting and conduct guidelines to ensure completeness and transparency of the CPG. RESULTS This CPG contains 40 recommendations regarding the prevention, screening, diagnosis, treatment, and follow-up of early gastric cancer based on available clinical studies and guidelines. We provide recommendations for the timing of Helicobacter pylori eradication, screening populations for early gastric cancer, indications for endoscopic resection and surgical gastrectomy, follow-up interval after treatment, and other recommendations. CONCLUSIONS This CPG can lead to optimum care for patients and populations by providing up-to-date medical information. We intend this CPG for widespread adoption to increase the standard of prevention, screening, diagnosis, treatment, and follow-up of early gastric cancer; thereby, contributing to improving national health care and patient quality of life.

Abstract
BACKGROUND Minimally invasive distal gastrectomy (MIDG) is non-inferior compared with open distal gastrectomy for gastric cancer. However, MIDG bears a learning curve (LC). This study aims to evaluate the number of cases required to surmount the LC (i.e. NLC) in MIDG. METHODS PubMed, Embase, Scopus, and the Cochrane Library were systematically searched from inception to August 2022 for studies which reported NLC in MIDG. NLC on reduced-port/single-port MIDG only were separately analysed. Poisson mean (95% confidence interval (CI)) was used to determine NLC. Negative binomial regression was used to compare NLC between laparoscopic distal gastrectomy (LDG) and robotic distal gastrectomy (RDG). RESULTS A total of 45 articles with 71 data sets (LDG n=47, RDG n=24) were analysed. There were 7776 patients in total (LDG n=5516, RDG n=2260). Majority of studies were conducted in East Asia (n=68/71). Majority (76.1%) of data sets used non-arbitrary methods of analyses. The overall NLC for RDG was significantly lower compared to LDG (RDG 22.4 (95% CI: 20.4-24.5); LDG 46.7 (95% CI: 44.1-49.4); incidence rate ratio 0.48, p<0.001). The median number of laparoscopic gastrectomy (LG) cases prior was 0 (interquartile range (IQR) 0-105) for LDG and 159 (IQR 101-305.3) for RDG. Meta-regression analysis did not show a significant impact prior experience in LG, extent of lymphadenectomy and intracorporeal vs extracorporeal anastomosis had on overall NLC for LDG and RDG. CONCLUSION NLC for RDG is shorter compared to LDG, but this may be due to prior experience in LG and ergonomic advantages of RDG.

Abstract
INTRODUCTION Radical gastrectomy has traditionally been the pillar treatment with curative intent for malignant tumors of the stomach. The safety of the laparoscopic approach for advanced gastric cancer (AGC) is still under debate. In our institution, laparoscopic gastrectomy is the most performed approach. OBJECTIVE Our aim is to describe the experience of a high-volume center in the treatment of AGC in Colombia and to analyze the short-term results and the overall survival rate at 1, 3, and 5 years comparing the open and laparoscopic approaches. METHODS A cross-sectional retrospective study of patients who underwent gastrectomy for advanced gastric cancer by open or laparoscopic approaches were performed. A Will-Coxon Mann Whitney test was performed in terms of lymph node status and surgical approach. Survival analysis was performed using the Kaplan-Meier method for overall survival at 1, 3, and 5 years. An initial log-rank test was performed to test the relationships between the operative variables and overall survival, the statistical value was accepted if p < 0.20. Data with an initial statistical relationship in the log-rank test were included in a secondary analysis using multivariate Cox proportional regression, variables with a value of p < 0.05 were considered statistically significant. RESULTS 310 patients met the inclusion criteria. 89% underwent laparoscopic gastrectomy and 10.9% open gastrectomy. The resection margins were negative at 93.5% and the In terms of lymph node dissection, the median lymph nodes extracted was 20 (12;37), with statistically significant differences between the approaches in favor of the laparoscopic approach (Median 21 vs 12; z = - 2.19, p = 0.02). The survival rate was at 1, 3, and 5 years of 84.04%, 66.9%, and 65.47% respectively. The presence of complications and the ICU requirement have a negative impact on survival at 1 year (p 0.00). CONCLUSION A laparoscopic approach is safe with acceptable morbidity and mortality rates for treating gastric cancer. D2 Lymphadenectomy could be performed successfully in a laparoscopic approach in a high-volume center and a properly standardized technique. Major postoperative morbidity with intensive care unit requirement seems to influence overall survival rates.

Abstract
BACKGROUND Laparoscopic gastrectomy (LG) has been widely used for advanced gastric cancer (GC), and its resection extent is not limited to distal gastrectomy. However, the superiority of this minimally invasive approach remains controversial. This study aimed to evaluate the benefits and risks of LG on the short- and long-term outcomes compared with open gastrectomy (OG) for GC. MATERIALS AND METHODS A systematic literature search was performed to identify randomized controlled trials (RCTs) comparing LG and OG for treatment of GC. The primary outcomes were adverse events, recurrence, mortality, and the quality of life. The secondary outcomes included operation-relevant outcomes and postoperative recovery outcomes. We employed random-effects meta-analyses to pool results with Hartung-Knapp adjustment. The prediction interval (PI) was used to quantify the between-study heterogeneity. Meta-regression and subgroup analyses were performed to examine the potential sources of heterogeneity. RESULTS Twenty-eight studies involving 7643 patients were included. Most studies (22 out of 28) reported results from experienced surgeons. Compared to OG, LG was found to have the advantages of less blood loss, fewer postoperative complications, and faster recovery, but at the expense of lesser proximal resection margin length, longer operation time, and fewer retrieved lymph nodes. There were no significant differences for anastomosis-related complications, recurrence and survival and other outcomes between LG and OG. Significant between-study heterogeneity was observed. Body mass index (BMI) and age were two major sources of heterogeneity. CONCLUSIONS For experienced surgeons, LG is an alternative approach to OG for patients with GC. Patients with lower BMI and older age may benefit most from LG. Future studies are needed to confirm our findings in low-volume hospitals and for less-experienced surgeons. Future trials focusing on patient-important outcomes are warranted for clinical decision-making.

Abstract
Objectives The effect of laparoscopic gastrectomy (LG) for the treatment of advanced gastric cancer (AGC) is still controversial. The aim of this meta-analysis was to contrast the short- and long-term outcomes of laparoscopic versus conventional open gastrectomy (OG) for patients with AGC. Methods Databases including PubMed, Embase, Scopus, and Cochrane Library were systematically searched until December 2021 for randomized controlled trial-enrolled patients undergoing LG or OG for the treatment of AGC. Short-term outcomes were overall postoperative complications, anastomotic leakage, number of retrieved lymph node, surgical time, blood loss, length of hospital stay, and short-term mortality. Long-term outcomes were survival rates at 1, 3, and 5 years. Results A total of 12 trials involving 4,101 patients (2,059 in LG group, 2,042 in OG group) were included. No effect on overall postoperative complications (OR 0.84, 95% CI 0.67 to 1.05, p = 0.12, I2 = 34%) and anastomotic leakage (OR 1.26, 95% CI 0.82 to 1.95, p = 0.30, I2 = 0%) was found. Compared with the open approach, patients receiving LG had fewer blood loss (MD -54.38, 95% CI -78.09 to -30.67, p < 0.00001, I2 = 90%) and shorter length of hospital stay (MD -1.25, 95% CI -2.08 to -0.42, p = 0.003, I2 = 86%). However, the LG was associated with a lower number of retrieved lymph nodes (MD -1.02, 95% CI -1.77 to -0.27, p = 0.008, I2 = 0%) and longer surgical time (MD 40.87, 95% CI 20.37 to 54.44, p < 0.00001, I2 = 94%). Furthermore, there were no differences between LG and OG groups in short-term mortality and survival rate at 1, 3, and 5 years. Conclusions LG offers improved short-term outcomes including shorter hospital stays and fewer blood loss, with comparable postoperative complications, short-term mortality, and survival rate at 1, 3, and 5 years when compared to the open approach. Our results support the implementation of LG in patients with AGC. Systematic Review Registration PROSPERO (CRD 42021297141).

Abstract
BACKGROUND It remains unclear whether laparoscopic conversation to open gastrectomy causes higher morbidity and has an adverse effect on the long-term survival outcomes of patients with gastric cancer. This study was designed to evaluate the impact of the conversion on short and long-term outcomes of patients with locally advanced gastric cancer (AGC). METHODS We retrospectively investigated 871 patients who initially underwent laparoscopic gastrectomy (LG) for pathologically confirmed diagnosis of AGC between February 2009 and April 2018. The patients were grouped as the conversion (CONV) group and completed laparoscopic (LAP) group. The 1:2 propensity score matching was performed to reduce the effect of bias due to the imbalanced baseline features between the two groups. Multivariate analyses were performed to identify risk factors for conversion and poor survival. RESULTS After propensity-score matching, 168 patients (56 in the CONV group and 112 in the LAP group) were studied. The CONV group was associated with significantly longer operation time (252.4 vs. 216.7 min, P < 0.001) and greater estimated blood loss (234.8 vs. 171.2 ml, P < 0.001) as compared with the LAP group. The time to first flatus (3.8 vs. 3.3 days, P = 0.043), time to start a liquid diet (4.1 vs. 3.5 days, P = 0.021), and postoperative hospital stay (8.7 vs. 7.6 days, P = 0.020) were significantly longer in the CONV group than that in the LAP group. The overall complication rate did not differ significantly between the CONV group and the LAP group (16.1% vs. 12.5%, P = 0.692). Both 5-year overall survival (OS) and 5-year disease-free survival (DFS) did not differ significantly between the CONV group and the LAP group (P = 0.805, P = 0.945, respectively). Multivariate analysis showed that lymphovascular invasion and stage III were independent prognostic factors for poor OS and DFS, whereas conversion was not. CONCLUSIONS The conversion from laparoscopic to open gastrectomy had no negative impact on morbidity and long-term survival outcomes for patients with locally AGC.

Abstract
BACKGROUND The efficacy of laparoscopy for advanced gastric cancer (AGC) remains controversial. MATERIALS AND METHODS We conducted a literature search on the EMBASE, PubMed and Cochrane Library databases to identify relevant available articles published between the time of the databases' inception and July 2020. RESULTS A total of 14,689 patients were included in the 41 studies identified. A total of 6976 patients were in an laparoscopic approach group (LG) and 7713 patients were in an open approach group (OG). The meta-analysis showed that in randomized control trials (RCTs), LG were better than OG in terms of estimated blood loss, time to oral intake and time to first flatus while the operation time and proximal resection margin (PRM) were significantly worse in LG than in OG. In the non-RCTs, LG had shorter hospital stays, less blood loss, less intraoperative transfusion, less time to oral intake, time to first flatus, time to ambulation; less overall or serious complications; and better 3-year and 5-year overall or disease-free survival (DFS). Operation times and PRM were significantly worse for LGs. CONCLUSION The safety and effectiveness of laparoscopic surgery for AGC is not inferior to that of traditional open surgery, and to a certain extent, can reduce trauma, facilitate recovery, and be validated in RCTs and non-RCTs. In the real-world cohort, laparoscopic surgery for gastric cancer achieved a better survival rate and DFS rate. However, to evaluate the efficacy of these two methods more comprehensively, high-quality randomized controlled trials and longer follow-up times are still needed.

Abstract
BACKGROUND Laparoscopy for gastric cancer has not been as popular compared with other digestive surgeries, with conflicting reports on outcomes. The aim of this study focuses on the surgical techniques comparing open and laparoscopy by assessing the morbi-mortality and long-term complications after gastrectomy. METHODS A retrospective study (2013-2018) was performed on a prospective national cohort (PMSI). All patients undergoing resection for gastric cancer with a partial gastrectomy (PG) or total gastrectomy (TG) were included. Overall morbidity at 90 post-operative days and long-term results were the main outcomes. The groups (open and laparoscopy) were compared using a propensity score and volume activity matching after stratification on resection type (TG or PG). RESULTS A total of 10,343 patients were included. The overall 90-day mortality and morbidity were 7% and 45%, with reintervention required in 9.1%. High centre volume was associated with improved outcomes. There was no difference in population characteristics between groups after matching. An overall benefit for a laparoscopic approach after PG was found for morbidity (Open = 39.4% vs. Laparoscopy = 32.6%, p = 0.01), length of stay (Open = 14[10-21] vs. Laparoscopy = 11[8-17] days, p<0.0001). For TG, increased reintervention rate (Open = 10.8% vs. Laparoscopy = 14.5%, p = 0.04) and increased oesophageal stricture rate (HR = 2.54[1.67-3.85], p<0.001) were encountered after a laparoscopic approach. No benefit on mortality was found for laparoscopic approach in both type of resections after adjusted analysis. CONCLUSIONS Laparoscopy is feasible for PG with a substantial benefit on morbidity and length of stay, however, laparoscopic TG should be performed with caution, with of higher rates of reintervention and oesophageal stricture.

Laparoscopic versus open distal gastrectomy for advanced gastric cancer: A meta-analysis of randomized controlled trials and high-quality nonrandomized comparative studies. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2020; 46:1998-2010. [PMID: 32758382 DOI: 10.1016/j.ejso.2020.06.046] [Citation(s) in RCA: 31] [Impact Index Per Article: 6.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2020] [Revised: 06/01/2020] [Accepted: 06/29/2020] [Indexed: 02/05/2023]
Abstract
BACKGROUND Controversy persists about the effects of laparoscopic distal gastrectomy (LDG) versus open distal gastrectomy (ODG) on short-term surgical outcomes and long-term survival within the field of advanced gastric cancer (AGC). METHODS Studies published from January 1994 to February 2020 that compare LDG and ODG for AGC were identified. All randomized controlled trials (RCTs) were included. The selection of high-quality nonrandomized comparative studies (NRCTs) was based on a validated tool (Methodological Index for Nonrandomized Studies, MINORS). The short- and long-term outcomes of both procedures were compared. RESULTS Overall, 30 studies were included in this meta-analysis, which comprised of 8 RCTs and 22 NRCTs involving 16,029 patients (7864 LDGs, 8165 ODGs). The recurrence, 3-year disease-free survival (DFS), 3-year overall survival (OS), and 5-year OS rates for LDG and ODG were comparable. LDG was associated with a lower postoperative complication rate (OR 0.79; P < 0.00001), lower estimated volume of blood loss (WMD -102.21 mL; P < 0.00001), shorter postoperative hospital stay (WMD -1.96 days; P < 0.0001), shorter time to first flatus (WMD -0.54 day; P = 0.0007) and shorter time to first liquid diet (WMD -0.66 day; P = 0.001). The number of lymph nodes retrieved, mortality, intraoperative complications, intraoperative blood transfusion, and time to ambulation were similar. However, LDG was associated with a longer surgical time (WMD 33.57 min; P < 0.00001). CONCLUSIONS LDG with D2 lymphadenectomy is a safe and effective technique for patients with AGC when performed by experienced surgeons at high-volume specialized centers.

Abstract
BACKGROUND While multiple Asian and a few Western retrospective series have demonstrated the feasibility and safety of robotic-assisted gastrectomy for gastric cancer, its reliability for thorough resection, especially for locoregional disease, has not yet been firmly established, and reported learning curves vary widely. To support wider implementation of robotic gastrectomy, we evaluated the learning curve for this approach, assessed its oncologic feasibility, and created a selection model predicting the likelihood of conversion to open surgery in a US patient population. PATIENTS AND METHODS We retrospectively reviewed data on all consecutive patients who underwent robotic gastrectomy at a high-volume institution between May 2012 and March 2019. RESULTS Of the 220 patients with gastric cancer selected to undergo curative-intent robotic gastrectomy, surgery was completed using robotics in 159 (72.3%). The median number of removed lymph nodes was 28, and ≥ 15 lymph nodes were removed in 94% of procedures. Surgical time decreased steadily over the first 60-80 cases. Complications were generally minor: 7% of patients experienced complications of grade 3 or higher, with an anastomotic leak rate of 2% and mortality rate 0.9%. Factors predicting conversion to open surgery included neoadjuvant chemotherapy, BMI ≥ 31 kg/m2, and tumor size ≥ 6 cm. CONCLUSIONS These findings support the safety and oncologic feasibility of robotic gastrectomy for selected patients with gastric cancer. Proficiency can be achieved by 20 cases and mastery by 60-80 cases. Ideal candidates for this approach are patients with few comorbidities, BMI < 31 kg/m2, and tumors < 6 cm.

Abstract
BACKGROUND Additional studies comparing laparoscopic gastrectomy (LG) versus open gastrectomy (OG) for advanced gastric cancer (AGC) have been published, and it is necessary to update the systematic review of this subject. OBJECTIVE We conducted the meta-analysis to find some proof for the use of LG in AGC and evaluate whether LG is an alternative treatment for AGC. METHOD Randomized controlled trials (RCT) and high-quality retrospective studies (NRCT) compared LG and OG for AGC, which were published in English between January 2010 and May 2019, were search in PubMed, Embase, and Web of Knowledge by three authors independently and thoroughly. Some primary endpoints were compared between the two groups, including intraoperative time, intraoperative blood loss, harvested lymph nodes, first flatus, first oral intake, first out of bed, post-operative hospital stay, postoperative morbidity and mortality, rate of disease recurrence, and 5-year over survival (5-y OS). Besides, considering for this 10-year dramatical surgical material development between 2010 and 2019, we furtherly make the same analysis based on recent studies published between 2016 and 2019. RESULT Thirty-six studies were enrolled in this systematic review and meta-analysis, including 5714 cases in LAG and 6094 cases in OG. LG showed longer intraoperative time, less intraoperative blood loss, and quicker recovery after operations. The number of harvested lymph nodes, hospital mortality, and tumor recurrence were similar. Postoperative morbidity and 5-y OS favored LG. Furthermore, the systemic analysis of recent studies published between 2016 and 2019 revealed similar result. CONCLUSION A positive trend was indicated towards LG. LG can be performed as an alternative to OG for AGC.

Abstract
INTRODUCTION Although the first laparoscopic gastrectomy was performed in 1991, there was a long delay until it was incorporated into the regular practice of western surgeons. In Brazil, there are only few case series reported and data on its safety and efficacy along with mid- and long-term results are desired. OBJECTIVE Present the mid-term results of laparoscopic gastrectomy with curative intent in the treatment of gastric adenocarcinoma and review the current evidence on the therapy of this neoplasia with the laparoscopic access. METHODS Patients who underwent D2 laparoscopic gastrectomy for gastric adenocarcinoma were retrospectively reviewed. RESULTS Sixty-nine patients met the inclusion criteria. The mean age was 59.2 years and the mean body mass index was 24.2 kg/m2. Subtotal gastrectomy was performed in 73.9%. The mean number of harvested lymph nodes was 36.7, increased lymph node count and shorter operative time were observed in the last 34 cases. Median hospital stay was 8 days. Postoperative complications occurred in 22 (31.9%) cases. Surgical mortality was 4.3%. CONCLUSION Laparoscopic gastrectomy can be performed safely with excellent short- and mid-term results. As experience increases, surgical duration is reduced and lymph node count rises.

Abstract
Laparoscopy-assisted distal gastrectomy (LADG) is a complicated procedure. To reduce the difficulty of the operation and standardize the surgical procedure, we explored a new operation mode, which we termed modularized LADG (MLADG). To further extend the new operation mode, we conducted this study to evaluate the short-term outcomes of MLADG for advanced gastric cancer, and determine the learning curve.Data from 100 consecutive patients who received LADG between October 2016 and October 2017 were retrospectively analyzed. Short-term outcomes, such as operation time and intraoperative blood loss, were evaluated, and the learning curve was calculated.For MLADG, the mean operation time was 168.2 ± 13.0 minutes, the mean intraoperative blood loss was 93.6 ± 29.1 ml, the mean number of harvested lymph nodes was 28.6 ± 4.2, and conversion to open surgery occurred in only 1 case. In addition, MLADG had an acceptable postoperative complication incidence and fast postoperative recovery. After the first 20 cases, the operation skill reached a mature and stable level.Our results indicate that MLADG is an oncologically feasible and technically safe surgical procedure. For the trainees with rich experience in open distal gastrectomy, the learning curve is considered to be completed after 20 MLADG cases.

Abstract
Purpose Senior surgeons prefer open gastrectomy (OG), while young surgeons prefer laparoscopic gastrectomy (LG). The purpose of this study was to evaluate the surgical outcomes of LG performed by a senior surgeon who was an expert in OG during his learning period, by comparing them with LGs performed by a young surgeon. Materials and Methods A senior surgeon performed 50 curative gastrectomies with laparoscopy (LG-S group) from March 2015 to August 2016. A young surgeon's initial 50 LGs comprised the LG-Y group. Clinicopathological characteristics and surgical outcomes were compared between the LG-S and LG-Y groups. Results D2 lymphadenectomy was more frequently performed in the LG-S group than in the LG-Y group (P=0.029). The operation time and number of retrieved lymph nodes did not significantly differ between the 2 surgeons (P=0.258 and P=0.410, respectively). Postoperative hospital stay and postoperative complication rate were similar between 2 groups (P=0.234 and P=1.000, respectively). Similarly, significant decreases in operation time with increasing case numbers were observed for both surgeons, whereas the number of retrieved lymph nodes increased significantly in the LG-Y group but not in the LG-S group. Conclusions The LG outcomes when performed by the senior surgeon were comparable to those when performed by the young surgeon, despite performing more extended lymphadenectomies. Senior surgeons who are experts in OG should not refrain from performing LG.

Abstract
PURPOSE This study aimed to evaluate the surgical outcomes and clinical safety of laparoscopic distal gastrectomy (LDG) when performed by trainee surgeons with little prior experience in performing open gastrectomy, under the guidance of trainer surgeons. METHODS From January 2008 until March 2015, 17 trainee surgeons and 5 trainer surgeons performed LDGs to treat 371 patients with clinical stage T1-T3 gastric cancer. Of these patients, 140 and 231 underwent LDG performed by trainee surgeons and trainer surgeons, respectively. We retrospectively analyzed the surgical outcomes of the two groups. RESULTS Trainee surgeons required significantly longer operation times than the trainer surgeons, with respective mean operation times of 262 and 223 min (p < 0.001). However, the mean blood loss volumes, average numbers of retrieved lymph nodes, postoperative complications, and postoperative hospital stay lengths did not differ significantly between LDGs performed by trainee surgeons and trainer surgeons. CONCLUSIONS The study findings suggest that, under the guidance of trainer surgeons, trainee surgeons with little experience with open gastrectomy and even without prior experience with LDG can perform radical surgeries safely.

Abstract
Minimally invasive gastric resections carry several advantages, including less intraoperative blood loss, faster recovery time, reduced pain, and decreased hospital length of stay and quicker return to work. Numerous trials have proved that laparoscopic and robotic-assisted gastrectomy provides equivalent surgical and oncologic outcomes to open approaches. As with any minimally invasive approach, advanced minimally invasive training and good judgment by a surgeon are paramount in selecting patients in whom a minimally invasive approach is feasible. With increasing research in patient populations with more advanced disease, the indications are likely to continue to expand.

Abstract
BACKGROUND Hospital volume is known to be a crucial factor in reducing postoperative morbidity and mortality in laparoscopic gastrectomy for gastric cancer. However, it is unclear whether surgeon's individual experience can overcome the effect of hospital volume. METHODS Clinicopathologic data of initial 50 laparoscopic gastrectomy cases were collected from six gastric cancer surgeons. Half of the six surgeons worked in high-volume centers, and the other half worked in low-volume hospitals. Perioperative outcomes were compared between the high-volume centers and the low-volume hospitals. RESULTS Three low-volume hospitals in this study contained significantly more male and older patients with a higher American Society of Anesthesiologists score than high-volume centers. Although high- and low-volume hospitals mainly used laparoscopy-assisted and totally laparoscopic approach, respectively, there were no differences between the two groups in the extent of resection, operating time, estimated blood loss, and number of collected lymph nodes. Postoperative recovery such as duration to soft diet and hospital stay did not differ between the high- and the low-volume hospitals. No significant difference was found in postoperative morbidities by Clavien-Dindo classification. There was no mortality reported in both groups of the enrolled hospitals. CONCLUSIONS Hospital volume is not a decisive factor in affecting postoperative morbidity and mortality for well-trained beginners in laparoscopic surgery for gastric cancer.

Inokuchi M, Otsuki S, Murase H, Kawano T, Kojima K. Feasibility of laparoscopy-assisted gastrectomy for patients with poor physical status: A propensity-score matching study. Int J Surg 2016; 31:47-51. [PMID: 27260314 DOI: 10.1016/j.ijsu.2016.05.066] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2016] [Revised: 05/11/2016] [Accepted: 05/29/2016] [Indexed: 12/13/2022]
Abstract
BACKGROUND Laparoscopically-assisted gastrectomy (LAG) has been established to be a minimally invasive treatment for early gastric cancer. However, few studies have shown the feasibility of LAG in patients with risky comorbidities according to the American Society of Anesthesiologists physical status (ASA-PS) classification. We performed this retrospective cohort study to assess the feasibility of LG in patients with an ASA-PS class of 3 or higher. METHODS We retrospectively identified 214 patients with an ASA-PS class of 3 or 4 among 1192 patients who underwent radical gastrectomy with lymph-node dissection between 1999 and 2014 in our hospital. Finally, 106 patients were generated by propensity-score matching between LAG and open gastrectomy (OG). Postoperative complications were compared between LAG and OG. RESULT The overall incidence of complications was the same in LAG (30%) and OG (30%). Surgical complications were similar in LAG and OG (19% and 17%, p = 0.80). Medical complications also did not differ significantly between LAG and OG (21% and 15%, p = 0.45). CONCLUSION LAG was a feasible procedure for patients with gastric cancer who had an ASA-PS class of 3 or 4 and could undergo general anesthesia. LAG can become an optional treatment for such risky patients.

Comparing the short-term outcomes of laparoscopic distal gastrectomy with D1+ and D2 lymph node dissection for gastric cancer. Asian J Endosc Surg 2016; 9:116-21. [PMID: 26804340 DOI: 10.1111/ases.12269] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/21/2015] [Revised: 09/28/2015] [Accepted: 11/23/2015] [Indexed: 12/12/2022]
Abstract
INTRODUCTION Laparoscopic distal gastrectomy (LDG) with D1+ lymph node dissection (LND) for early gastric cancer has been widely accepted. However, LDG with D2 LND for advanced gastric cancer remains in limited use. The aim of this retrospective study was to clarify the safety of LDG with D2 LND for gastric cancer. METHODS From January 2010 to September 2014, 296 patients underwent LDG; those who received D1+ LND (n = 230) or D2 LND (n = 66) were included in this study. The clinicopathological characteristics and short-term outcomes of both groups were investigated and compared. RESULTS There were no significant differences in the incidence of postoperative complications between the two groups. However, the frequency of infectious intra-abdominal complications was higher in the D2 LND group than in the D1+ LND group. Additionally, a lower risk of infectious intra-abdominal complications was seen with certified than with uncertified operators. CONCLUSION The evaluation of short-term outcomes demonstrated that LDG with D2 LND is generally feasible. However, the risk of infectious intra-abdominal complications is higher with D2 LND than with D1+ LND. Also, D2 LND should be performed by trained operators.

Abstract
BACKGROUND Although the frequency of laparoscopic total gastrectomy (LTG) has been increasing, the procedure requires considerable experience because of its technical difficulty and the concern for oncological safety. This study intended to define the learning curve associated with the procedure. METHODS All 256 cases of LTG performed from June 2003 to December 2012 were enrolled. The cases were divided into ten groups of 25 cases based on when they occurred. The learning curve was defined using the moving average method. LTG, performed in the absence of other procedures (pure-LTG, 132 cases), was extracted from the ten groups, and the mean operative time and estimated blood loss (EBL) were compared to define the learning curve. Retrieved lymph nodes, hospital stay, and complications were compared across the phases of the learning curve. LTG with spleen resection, performed in the absence of other procedures (pure-srLTG, 53 cases), was also analyzed by the same method. RESULTS A three-phase learning curve of LTG was defined: the first two groups, the following two groups, and the final six groups (mean operative time: 223.0, 244.8, and 207.8 min, respectively, p = 0.003; mean EBL: 94.6, 237.0, and 116.5 ml, respectively, p < 0.001). The rates of complications and open conversions were similar across the three phases. There were no significant differences in mean operative time, EBL, retrieved LNs, hospital stay, or complication rates between pure-LTG and pure-srLTG, after completing the respective learning curves. CONCLUSIONS Experience with approximately 100 LTG cases was required to complete learning of the procedure.

Abstract
PURPOSE Obesity is associated with morbidity following gastric cancer surgery, but whether obesity influences morbidity after laparoscopic gastrectomy (LG) remains controversial. The present study evaluated whether body mass index (BMI) and visceral fat area (VFA) predict postoperative complications. MATERIALS AND METHODS A total of 217 consecutive patients who had undergone LG for gastric cancer between May 2003 and December 2005 were included in the present study. We divided the patients into two groups ('before learning curve' and 'after learning curve') based on the learning curve effect of the surgeon. Each of these groups was sub-classified according to BMI (<25 kg/m(2) and ≥25 kg/m(2)) and VFA (<100 cm(2) and ≥100 cm(2)). Surgical outcomes, including operative time, quantity of blood loss, and postoperative complications, were compared between BMI and VFA subgroups. RESULTS The mean operative time, length of hospital stay, and complication rate were significantly higher in the before learning curve group than in the after learning curve group. In the subgroup analysis, complication rate and length of hospital stay did not differ according to BMI or VFA; however, for the before learning curve group, mean operative time and blood loss were significantly higher in the high VFA subgroup than in the low VFA subgroup (P=0.047 and P=0.028, respectively). CONCLUSIONS VFA may be a better predictive marker than BMI for selecting candidates for LG, which may help to get a better surgical outcome for inexperienced surgeons.

Abstract
Laparoscopic-assisted distal gastrectomy (LADG) with D2 resection is gradually being performed for treating advanced gastric cancer. This meta-analysis aims to compare the clinical outcomes between LADG and open distal gastrectomy (ODG) when considering the impact of the learning curve. The PubMed, Embase, and ISI databases and the Cochrane Library were electronically searched. Randomized controlled trails and retrospective comparative studies published between 1994 and 2013 were collected. We divided the included studies into two subgroups according to whether the authors had experience of at least or fewer than 40 cases of LADG with D2 resection and then compared the operative time, intraoperative bleeding, the amount of resected lymph nodes, short-term recovery parameters, and complications between LADG and ODG groups. Ten comparative studies including 1100 patients were selected. Meta-analysis showed that when LADG was compared with ODG, surgeons with experience of at least 40 cases could achieve more resected lymph nodes (P=.002), reduced time to flatus (P<.0001), shortened time to liquid diet (P<.00001), and lower complication rates (P=.02). However, the above advantages of LADG faded in the subgroup of surgeons with experience of fewer than 40 cases. Our meta-analysis suggested that the learning curve has significant effects on most of the important surgical and short-term recovery outcome parameters. Accomplishment of 40 cases of LADG with D2 lymphadenectomy is required to achieve optimum proficiency.

Abstract
OBJECTIVE This study aims to answer the superiority of comparing laparoscopy-assisted distal gastrectomy (LADG) with open distal gastrectomy (ODG) in the treatment early gastric cancer (EGC). MATERIAL AND METHODS A comprehensive search up to May 31, 2014 was conducted on PubMed, Web of science, and the Cochrane Library. All eligible studies comparing LADG versus ODG were included. Data synthesis and statistical analysis were performed using RevMan 5.2 software. RESULTS Seven randomized controlled trials (RCTs) totaling 390 patients (195 LADG and 195 ODG) were analyzed. Compared to ODG, LADG showed longer operative time (WMD = 79.60; 95%CI = 59.86 to 99.35; P < 0.00001), but was associated with less blood loss (WMD = -108.11; 95%CI = -145.97 to -70.26; P < 0.00001), fewer administered analgesics (WMD = -1.70; 95%CI = -2.19 to -1.22; P < 0.00001), fewer number of harvested lymph node (WMD = -2.77; 95%CI = -4.38 to -1.16; P = 0.0007), lower incidence of postoperative complications (OR = 0.26; 95%CI = 0.13 to 0.54; P = 0.0003), shorter postoperative hospital stay (WMD = -1.0; 95% CI = -1.83 to -0.16; P = 0.02) and earlier passage of flatus (WMD = -0.62; 95% CI = -0.96 to -0.27; P = 0.0005). CONCLUSION This meta-analysis demonstrated that LADG significantly reduced blood loss, decreased the frequency of analgesic administration, faster recovery, a shorter hospital stay and fewer postoperative complications compared with ODG, though at the price of longer operative times and the number of harvested lymph nodes lesser as compared to ODG.

Abstract
AIM: To describe the learning curves of hand-assisted laparoscopic D2 radical gastrectomy (HALG) for the treatment of gastric cancer.
METHODS: The HALG surgical procedure consists of three stages: surgery under direct vision via the port for hand assistance, hand-assisted laparoscopic surgery, and gastrointestinal tract reconstruction. According to the order of the date of surgery, patients were divided into 6 groups (A-F) with 20 cases in each group. All surgeries were performed by the same group of surgeons. We performed a comprehensive and in-depth retrospective comparative analysis of the clinical data of all patients, with the clinical data including general patient information and intraoperative and postoperative observation indicators.
RESULTS: There were no differences in the basic information among the patient groups (P > 0.05). The operative time of the hand-assisted surgery stage in group A was 8-10 min longer than the other groups, with the difference being statistically significant (P = 0.01). There were no differences in total operative time between the groups (P = 0.30). Postoperative intestinal function recovery time in group A was longer than that of other groups (P = 0.02). Lengths of hospital stay and surgical quality indicators (such as intraoperative blood loss, numbers of detected lymph nodes, intraoperative side injury, postoperative complications, reoperation rate, and readmission rate 30 d after surgery) were not significantly different among the groups.
CONCLUSION: HALG is a surgical procedure that can be easily mastered, with a learning curve closely related to the operative time of the hand-assisted laparoscopic surgery stage.

Abstract
AIM: To systematically review the surgical outcomes of totally laparoscopic gastrectomy (TLG) vs open gastrectomy (OG) for gastric cancer.
METHODS: A systematic search of PubMed, Embase, Cochrane Library, and Web of Science was conducted. All original studies comparing TLG with OG were included for critical appraisal. Data synthesis and statistical analysis were carried out using RevMan 5.1 software.
RESULTS: One RCT and 13 observational studies involving 1532 patients were included (721 TLG and 811 OG). TLG was associated with longer operation time [weighted mean difference (WMD) = 58.04 min, 95%CI: 37.77-78.32, P < 0.001], less blood loss [WMD = -167.57 min, 95%CI: -208.79-(-126.34), P < 0.001], shorter hospital stay [WMD = -3.75 d, 95%CI: -4.88-(-2.63), P < 0.001] and fewer postoperative complications (RR = 0.71, 95%CI: 0.58-0.86, P < 0.001). The number of harvested lymph nodes, surgical margin, mortality and cancer recurrence rate were similar between the two groups.
CONCLUSION: TLG may be a technically safe, feasible and favorable approach in terms of better cosmesis, less blood loss and faster recovery compared with OG.

Abstract
Gastric cancer poses a significant public health problem, especially in the Far East, due to its high incidence in these areas. Surgical treatment and guidelines have been markedly different in the West, but nowadays this debate is apparently coming to an end. Laparoscopic surgery has been employed in the surgical treatment of gastric cancer for two decades now, but with controversies about the extent of resection and lymphadenectomy. Despite these difficulties, the apparent advantages of the laparoscopic approach helped its implementation in early stage and distal gastric cancer, with an increase on the uptake for distal gastrectomy for more advanced disease and total gastrectomy. Nevertheless, there is no conclusive evidence about the laparoscopic approach yet. In this review article we present and analyse the current status of laparoscopic surgery in the treatment of gastric cancer.

Abstract
OBJECTIVE To discuss the learning curve of laparoscopy-assisted distal gastrectomy (LADG) with lymph node dissection and the oncological results and long-term outcomes of different periods in the learning stage. PATIENTS AND METHODS One hundred twenty-four patients with gastric cancer who received LADG with lymph node dissection from January 2004 to December 2009 were retrospectively reviewed and analyzed. They were divided into three groups (A-C) according to different operative date: 41 were in Group A (early), 41 in Group B (middle), and 42 in Group C (laer). There were no significant statistical differences among the three groups with respect to age, gender, early/advanced gastric cancer, Union for International Cancer Control stage, and lymph node dissection. Then the following items were compared in these groups: operative time, blood loss, number of lymph nodes harvested, postoperative complications, postoperative hospital stay, and long-term survival. RESULTS The operative time in Group A (235.0±50.3 minutes) was significantly longer than in Groups B (201.7±39.6 minutes) and C (199.0±44.7 minutes), but there was no significant difference between Groups B and C. The harvest of lymph nodes from Group A (11.0±5.5) was significantly less than from Groups B (16.3±9.2) and C (17.2±8.7), but there was no significant difference between Groups B and C. The postoperative hospital stay and complications, overall survival, and disease-free survival showed no difference among the three groups. CONCLUSIONS The learning curve of gastrointestinal surgeons with experience of laparoscopic operation is about 40 cases. The oncological principles and long-term outcomes were not sacrificed during the learning stage.

Abstract
Despite declining incidence, gastric cancer remains one of the most common cancers worldwide. Early detection in population-based screening programs has increased the number of cases of early gastric cancer, representing approximately 50% of newly detected gastric cancer cases in Asian countries. Endoscopic mucosal resection and endoscopic submucosal dissection have become the preferred therapeutic techniques in Japan and Korea for the treatment of early gastric cancer patients with a very low risk of lymph node metastasis. Laparoscopic and robotic resections for early gastric cancer, including function-preserving resections, have propagated through advances in technology and surgeon experience. The aim of this paper is to discuss the recent advances in minimally invasive approaches in the treatment of early gastric cancer.

Jeong O, Ryu SY, Choi WY, Piao Z, Park YK. Risk factors and learning curve associated with postoperative morbidity of laparoscopic total gastrectomy for gastric carcinoma. Ann Surg Oncol 2014; 21:2994-3001. [PMID: 24687152 DOI: 10.1245/s10434-014-3666-x] [Citation(s) in RCA: 45] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2013] [Indexed: 12/28/2022]
Abstract
BACKGROUND Laparoscopic total gastrectomy (LTG) is a challenging surgical procedure that has substantial technical difficulties and complications. In this study, we investigated risk factors for morbidity and mortality after LTG, and the learning curve associated with postoperative morbidity. METHODS Prospectively constructed data of 203 patients undergoing LTG between 2004 and 2013 were retrospectively reviewed. The multivariate logistic regression model was used to analyze risk factors for postoperative morbidity. The Cumulative Sum (CUSUM) technique was used to assess the learning curve. RESULTS Postoperative morbidity and mortality after LTG was 18.7 and 1.5 %, respectively. Of 38 patients with postoperative morbidity, 7 (3.4 %) were managed with reoperation, 8 (4.0 %) with radiologic or endoscopic intervention, and 23 (11.3 %) with a conservative treatment. Of local complications, gastrointestinal bleeding was the most common (12 patients), followed by anastomosis leakage (9 patients) and intra-abdominal abscess (9 patients). Respiratory complication was the most common of the systemic complications. There were 17 cases (8.4 %) of complications exceeding grade III severity, of which anastomosis leakage was the most common. CUSUM analysis showed that postoperative morbidity reached a plateau after around 45 cases. Univariate and multivariate analyses revealed that old age (over 65 years of age) and surgical experience (<45 cases) were independent factors for postoperative morbidity after LTG. CONCLUSION LTG is a feasible technique with acceptable morbidity and mortality. However, substantial surgical experience is of most importance to reduce postoperative morbidity and mortality.

Abstract
BACKGROUND The use of laparoscopic gastrectomy (LG) in advanced gastric cancer (AGC) remains a controversial topic, mainly because of doubts about its oncologic validity. This study is a systematic review and meta-analysis of the available evidence. METHODS A comprehensive search was performed until June 2013 to identify comparative studies evaluating survival rates, recurrence rates, surgical outcomes and complications. Pooled risk ratios (RR) and weighted mean differences (WMD) with 95% confidence intervals (CI) were calculated using the random effects model. Data synthesis and statistical analysis were carried out using RevMan 5.1 software. RESULTS Fifteen trials were involved in this analysis. Compared to open gastrectomy (OG), LG involved a longer operating time (WMD = 48.67 min, 95% CI 34.09 to 63.26, P < 0.001); less blood loss (WMD = -139.01 ml, 95% CI -174.57 to -103.44, P < 0.001); earlier time to flatus (WMD = -0.79 days, 95% CI -1.14 to -0.44, P < 0.001); shorter hospital stay (WMD = -3.11 days, 95% CI -4.13 to -2.09, P < 0.001); and a decrease in complications (RR = 0.74, 95% CI 0.61 to 0.90, P = 0.003). There was no significant difference in the number of harvested lymph nodes, margin distance, mortality, cancer recurrence rate and long-term survival rate between the AGC patients treated with LG or OG (P > 0.05). CONCLUSIONS Despite a longer operation, LG is a safe technical alternative to OG for AGC with a lower complication rate and enhanced postoperative recovery. Moreover, there were similar outcomes between both approaches in terms of cancer recurrence and the long-term survival rate. Because of the limitation of this study, methodologically high-quality studies are needed for further evaluation.

Abstract
BACKGROUND Laparoscopic gastrectomy (LAG) is increasingly performed to treat gastric cancer. However, the procedure remains complicated, and an optimal system for educating clinicians about LAG has not been established. METHODS Our training system centers on understanding the anatomical appearance under laparoscopy and the standardized steps of LAG, including the roles of the scopist and the assistant. The trainees participated in LAG procedures as a scopist and an assistant in 30-35 cases, before conducting their first LAG case. The data of 788 consecutive patients with early gastric cancer who underwent LAG were also reviewed. RESULTS During the study period, nine trainees performed a total of 215 LAG (27.3 %) with trainers, while 563 LAG were conducted by the two trainers (71.4 %). The surgical outcomes including operative time, blood loss, and retrieval of lymph nodes were almost equivalent for both the trainers and the trainees. The total experience among the trainees as scopist and as first assistant was 45.0 and 41.4 cases, respectively, and the trainees had experienced 33.8 cases as a scopist and 35.3 cases as an assistant before they performed their first LAG as an operator. After commencing experience as an operator, the average operation time of the trainees reached that of the trainers within six cases and their learning curve reached a plateau. CONCLUSIONS Our training system based on attaining sufficient experience as an assistant and scopist in the simulation of a LAG procedure was effective for ensuring clinical safety for LAG performed by a trainee with experienced surgeons.

Abstract
Purpose The intracorporeal reconstruction after laparoscopic gastrectomy can minimize postoperative pain, and give better cosmetic effect, while it may have technical difficulties and require the learning curve. This study aimed to analyze the surgical outcome of intracorporeal reconstruction according to the surgeon's experience comparing with extracorporeal procedure. Materials and Methods From January 2009 to September 2011, intracorporeal reconstruction in laparoscopic surgery for gastric cancer was performed for 71 patients (Intra group). During same period, 231 patients underwent laparoscopy-assisted gastrectomy (Extra group). These patients were classified into initial (1st to 20th case of intra group), intermediate (21th to 46th case), and experienced (after 47th case) phases. Results Intracorporeal procedures included 35 cases of Billroth-I, 30 Billroth-II and 6 Roux en Y reconstructions. In the initial phase, operation time (P=0.022) were significantly longer for the patients of intra group than them of extra group. Although the difference was not significant, the length of hospital stay was longer and complication rate was higher in the intra group. In intermediate and experienced phases, there was no difference between two groups in operation time and hospital stay. In these phases, complication rate was lower in the intra group than the extra group (3.9% versus 9.7%). The pain scale was significantly lower post operation day 5 in the intra group. Conclusions Intracorporeal reconstruction after laparoscopic distal gastrectomy was feasible and safe, and the technique was stabilized after 20th case if the surgeon has sufficient experiences when we compared it with extracorporeal reconstruction.

Laparoscopy versus open distal gastrectomy by expert surgeons for early gastric cancer in Japanese patients: short-term clinical outcomes of a randomized clinical trial. Surg Endosc 2012; 27:1695-705. [PMID: 23247737 DOI: 10.1007/s00464-012-2658-9] [Citation(s) in RCA: 88] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2011] [Accepted: 10/03/2012] [Indexed: 12/29/2022]
Abstract
BACKGROUND Short-term outcomes of laparoscopy-assisted distal gastrectomy (LADG) and open DG (ODG) have been investigated in previous clinical trials, but operative techniques and concomitant treatments have evolved, and up-to-date evidence produced by expert surgeons is required to provide an accurate image of the relative efficacies of the treatments. The purpose of this study was to compare laparoscopic versus ODG with respect to specific primary and secondary short-term outcomes. METHODS From October 2005 to February 2008, a total of 64 patients with early gastric cancer were randomly assigned to the LADG or the ODG group. One patient was excluded due to concurrent illness unrelated to the intervention, so the data from 63 patients were analyzed. The primary short-term outcome was the 4-day postoperative use of analgesics. Secondary short-term outcomes were postoperative residual pain, complications, days hospitalized, blood data, days with fever, and days to first flatus. RESULTS There was a significant difference in favor of LADG for postoperative use of analgesics (P = 0.022). Unexpectedly, there was no significant difference in degree of pain in the immediate postoperative period, putatively due to the optimal use of analgesics. Of the secondary outcomes, residual pain at postoperative day 7 (P = 0.003) and days to first flatus (P = 0.001) were significantly better with LADG. Postoperative complications, number of days hospitalized, and number of days with fever were also better with LADG, but the differences were not significant. Blood data representing inflammation (WBC and CRP) showed marked differences, especially on postoperative day 7 (P = 0.0016 and P = 0.0061, respectively). CONCLUSIONS LADG performed by expert surgeons results in less postoperative pain accompanied by decreased surgical invasiveness and is associated with fewer postoperative inconveniences. No preliminary suggestions of changes in long-term curability were observed. LADG for early gastric cancer is a feasible and safe procedure with short-term clinical results superior to those of ODG.

Abstract
BACKGROUND The application of laparoscopic surgery for advanced gastric cancer (AGC) remains questionable on account of technical difficulty of D2 lymphadenectomy, and there has been few large-scale follow-up results regarding the oncological adequacy of laparoscopic surgery compared with that of open surgeries for AGC. The aim of this study is to evaluate technical feasibility and oncological efficacy of laparoscopy-assisted gastrectomy (LAG) for advanced gastric cancer without serosal invasion. METHODS From January 2008 to December 2012, 1114 patients with gastric cancer underwent D2 gastrectomy, including 336 T2 and T3 patients in term of depth of invasion. Of all 336 patients, 224 underwent LAG, while open gastrectomy (OG) performed on the other 112 patients. The comparison was based on the clinicopathologic characteristics, surgical outcome, and follow-up results. RESULTS There are not significant differences in clinicopathological characteristics between the two groups (P > 0.05). The operation time and first ambulation time was similar in the two groups. However, estimated blood loss, bowel function recovery time and duration of hospital stay were significantly less in the LAG group. No significant difference in morbidity and mortality was found between the LAG group and OG group (11.1% vs. 15.3%, P = 0.266; 0.9% vs. 1.8%, P = 0.859). The mean number of resected lymph nodes (LNS) between the LAG group and OG group was similar (30.6 ± 10.1 vs. 30.3 ± 8.6, P = 0.786). Furthermore, the mean number of removed LNS in each station was not significantly different in the distal gastrectomy and total gastrectomy (P > 0.05). No statistical difference was seen in 1 year survival rate (91.5% vs. 89.8% P > 0.05) and the survival curve after surgery between the LAG group and OG group. CONCLUSION Laparoscopy-assisted D2 radical gastrectomy is feasible, effective and has comparative oncological efficacy compared with open gastrectomy for advanced gastric cancer without serosal invasion.

Abstract
Application of minimally invasive techniques to gastric cancer in the West has been curbed by concerns of feasibility and oncologic adequacy. Growing evidence supports improved short-term and equivalent oncologic outcomes in selected patients undergoing laparoscopic surgery for early-stage disease. Laparoscopic resection for advanced gastric cancer remains controversial due to few reliable studies on long-term outcomes. We focus on important studies from Asia and highlight the Western experience with laparoscopic and robotic surgery for gastric carcinoma.

Abstract
BACKGROUND Laparoscopy-assisted gastrectomy (LAG) is an advanced surgery that requires the mastery of complex surgical skills. We evaluate the feasibility of LAG with systemic lymph node dissection when participating surgeons have sufficient knowledge and experience to conduct open surgery for gastric cancer and basic laparoscopic skills. METHODS All operations were performed by two Japan Surgical Society board-certified attending surgeons who had performed over 50 conventional gastrectomies and 30 laparoscopic cholecystectomies. The surgeons went through an established program, including training at the wet and dry laboratories. In addition, surgeries for the first 10 cases were assisted by an expert surgeon with experience of >300 cases. To be eligible for the LAG procedure, patients had to have a preoperative diagnosis of T1, N0 and M0 gastric carcinoma. The morbidity rate was used as the study endpoint. Variables such as operating time, intraoperative blood loss and number of retrieved lymph nodes were evaluated as complementary surgical endpoints. These variables were compared between the first 25 cases and the latter 25 cases. RESULTS A total of 50 patients who were scheduled to undergo LAG were prospectively enrolled between 2005 and 2008. Morbidity rate was 4% (2/50), with one case due to intestinal injury and one case due to an intra-abdominal abscess. Complications related to laparoscopy were observed in 2% (1/50), with one case of mesenteric injury. The conversion rate to laparotomy was 6% (3/50). However, there were no serious consequences in converted cases. The operating time was 263.7 ± 45.0 min. The intraoperative blood loss was 94.5 ± 106.5 g. The total number of regional lymph nodes retrieved was 34.7 ± 12.2. A significant improvement in the blood loss was only noted after the first 25 procedures. All patients are alive and disease-free after a median follow-up of 38.8 months. CONCLUSION An adequate training program, including site visits by expert surgeons, in conjunction with basic laparoscopy skills and solid backgrounds in open gastrectomy from the perspective of the trainees are currently key to the successful and safe implementation of LAG. Whether the procedure is oncologically feasible remains to be confirmed by long-term follow-up.

Abstract
OBJECTIVE To perform a meta-analysis of high-quality published trials, randomized and observational, comparing laparoscopic distal gastrectomy (LDG) and open distal gastrectomy (ODG) for gastric cancer. BACKGROUND Controversy persists about the clinical utility of minimally invasive techniques for the treatment of gastric cancer. Prospective data is limited to a few small randomized trails. METHODS : Studies published from January 1992 to March 2010 that compare LDG and ODG were identified. No restrictions in pathologic stage were applied. All randomized controlled trials (RCTs) were included. Selection of high-quality, nonrandomized comparative studies (NRCTs) was based on a validated tool (Methodological Index for Nonrandomized Studies). Mortality, complications, harvested lymph nodes, operative time, blood loss, and hospital stay were compared using weighted mean differences (WMDs) and odds ratios (ORs). RESULTS Twenty-five studies were included in the analyses, 6 RCTs and 19 NRCTs, compromising 3055 patients (1658 LDG, 1397 ODG). LDG was associated with longer operative times (WMD 48.3 minutes; P < 0.001) and lower overall complications (OR 0.59; P < 0.001), medical complications (OR 0.49; P = 0.002), minor surgical complications (OR 0.62; P = 0.001), estimated blood loss (WMD -118.9 mL; P < 0.001), and hospital stay (WMD -3.6 days; P < 0.001). Mortality and major complications were similar. Patients in the ODG group had a significantly higher number of lymph nodes harvested (WMD 3.9 nodes; P < 0.001), although the estimated proportion of patients with less than 15 retrieved nodes was similar (OR 1.26, P = 0.09). CONCLUSIONS LDG can be performed safely with a shorter hospital stay and fewer complications than open surgery. The long-term significance of a difference of less than 5 nodes in the number of harvested lymph nodes remains unclear. Lymph node staging appears to be unaffected. These results need to be validated in Western patients with advanced gastric cancer.

Abstract
There has been much speculation regarding differences in outcome for patients who have gastric cancer in the Eastern versus Western world. Among other factors, these differences have contributed to a unique cohort of patients and experience in the Western staging/evaluation of gastric cancer and in the application of minimally invasive approaches for treatment. This review summarizes the current state of laparoscopic approaches for the staging and treatment of gastric adenocarcinoma for patients presenting in Western countries, with their associated unique presentation, comorbidities, and outcomes.

Abstract
Purpose In laparoscopic distal gastrectomy for gastric cancer, most surgeons prefer extra-corporeal anastomosis because of technical challenges and unfamiliarity with intra-corporeal anastomosis. Herein, we report the feasibility and safety of intra-corporeal Billroth-II anastomosis in gastric cancer. Methods From April 2004 to March 2011, 130 underwent totally laparoscopic distal gastrectomy with intra-corporeal Billroth-II reconstruction, and 269 patients underwent laparoscopy-assisted distal gastrectomy with extra-corporeal Billroth-II reconstruction. Surgical efficacies and outcomes between two groups were compared. Results There were no differences in demographics and clinicopathological characteristics. The mean operation and reconstruction times of totally laparoscopic distal gastrectomy were statistically shorter than laparoscopy-assisted distal gastrectomy (P = 0.019; P < 0.001). Anastomosis-related complications were observed in 11 (8.5%) totally laparoscopic distal gastrectomy and 21 (7.8%) laparoscopy-assisted distal gastrectomy patients, and the incidence of these events was not significantly different. Post-operative hospital stays for totally laparoscopic distal gastrectomy were shorter than laparoscopy-assisted distal gastrectomy patients (8.3 ± 3.2 days vs. 9.9 ± 5.3 days, respectively; P = 0.016), and the number of times parenteral analgesic administration was required in laparoscopy-assisted distal gastrectomy patients was more frequent after surgery. Conclusion Intra-corporeal Billroth-II anastomosis is a feasible procedure and can be safely performed with the proper experience for laparoscopic distal gastrectomy. This method may be less time consuming and may produce a more cosmetic result.

Abstract
BACKGROUND The aim of this study was to clarify the technical feasibility and oncological efficacy of laparoscopy-assisted gastrectomy (LAG) for gastric cancer compared with open gastrectomy (OG). METHODS Between April 2002 and March 2008, a series of 623 patients with gastric cancer underwent R0 gastrectomy (314 LAG patients and 309 OG patients). Age, gender, lymph node dissection, and pathological stage were matched by propensity scoring, and 212 patients (106 LAG and 106 OG) were selected for analysis after the exclusion of 40 patients who had proximal gastrectomy. Intraoperative factors, postoperative morbidity, long-term quality of life (QOL), and survival were evaluated. Moreover, these outcomes were also compared between the laparoscopy-assisted total gastrectomy (LATG) and the open total gastrectomy (OTG). RESULTS There was no significant difference in preoperative characteristics between the two patient groups. Regarding intraoperative characteristics, blood loss was significantly lower in the LAG group (143 ml) than in the OG group (288 ml), while operation time was significantly longer in the LAG group (273 min) than the OG group (231 min). The degree of lymph node dissection and number of retrieved lymph nodes did not differ between the two groups. There were no significant differences in postoperative courses or overall and disease-specific survival (89.8% vs. 83.6%, P = 0.0886; 100% vs. 95.2%, P = 0.1073) except time to first flatus and time to use of nonsteroidal anti-inflammatory derivatives between the two groups. Significantly fewer patients felt wound pain in the LAG group 1 year after surgery. Analyses between the LATG and OTG groups showed similar results. CONCLUSIONS LAG for gastric cancer may be both feasible and safe. However, it will be necessary to conduct a well-designed randomized controlled trial comparing short-term and long-term outcomes between LAG and OG in a larger number of patients.
