For treatment of common bile duct stones (CBDS), guidelines recommend a one-stage approach, including laparoscopic common bile duct exploration (LCBDE) or intraoperative endoscopic retrograde cholangiopancreatography (intraERCP). Studies show favourable outcomes with transcystic LCBDE (tLCBDE), but this technique is not widely adopted. The use of tLCBDE may be limited by several factors, but to what degree is unknown. The aim of this study is to examine the feasibility and, secondarily, outcomes of tLCBDE for patients undergoing removal of CBDS and laparoscopic cholecystectomy (LC) when tLCBDE is the first-line treatment.

A retrospective cross-sectional study including patients with removal of CBDS and LC at Horsens Regional Hospital during June 2017-March 2022. We classified patients into three groups: tLCBDE, preoperative ERCP (preERCP), and other procedures. The reasons for not performing tLCBDE were registered from medical charts. In the tLCBDE and the preERCP group, we registered clearance rate, postoperative complications, and subsequent ERCP.

In total, 229 patients received a procedure due to CBDS, of which 73% were emergency procedures. The groups were as follows: 179 (78%) tLCBDE, 25 (11%) preERCP, and 25 (11%) other procedures. preERCP was chosen due to the patient being unfit for emergency surgery, tLCBDE not being technically possible, and other reasons. Other procedures were chosen, because tLCBDE was not technically possible, lack of equipment or qualified surgeon, and other reasons. In the tLCBDE group, 94% of patients with CBDS were cleared, 5.6% had a complication of Clavien-Dindo grade ≥ 3, and 3.9% patients needed a subsequent ERCP.

tLCBDE is feasible, safe, and effective treatment which can be performed in the majority of patients with CBDS and should be considered an equivalent to ERCP or choledochotomy as first-line treatment of patients with CBDS. As some patients require ERCP or choledochotomy, tLCBDE should not be the sole treatment available.

Common bile duct stones are a significant public health issue that often requires surgical intervention. Two primary surgical techniques for addressing these conditions are laparoscopic common bile duct exploration (LCBDE) and endoscopic retrograde cholangiopancreatography (ERCP) followed by laparoscopic cholecystectomy (LC) in 1 or 2 stages, respectively. This systematic review and meta-analysis compared the efficacy and results of these 2 techniques.

A systematic review and meta-analysis of randomized clinical trials followed the PRISMA and AMSTAR 2 guidelines. Literature research were performed in the Cochrane Library, PubMed/MEDLINE, Embase, and Google Scholar up to March 1, 2023.

Fourteen studies with a total of 1849 patients were included. The success rate was similar between LCBDE (872/919 patients) and ERCP followed by LC (866/930 patients) (odds ratio [OR] = 1.31; 95% confidence interval [CI] [0.76, 2.25], P = .33). There was no significant difference in residual stones (OR = 0.71; 95% CI [0.28, 1.83], P = .48), mortality (OR = 0.55; 95% CI [0.14, 2.14], P = .39), morbidity (OR = 0.87; 95% CI [0.66, 1.16], P = .36) or hospital stay (mean difference = -1.31; 95% CI [-2.89, 0.26], P = .10) between the 2 groups. Meta-analysis found no significant differences between LCBDE and ERCP followed by LC in terms of success rate, residual stones, mortality, morbidity or hospital stay.

Both techniques are viable options for the treatment of choledocholithiasis and gallbladder stones. More multicentric randomized controlled trials are recommended to confirm these findings and explore long-term outcomes.

We present the case of a 32-year-old woman who was ultimately diagnosed with obstructive jaundice. She exhibited persist jaundice, liver dysfunction with normal drainage of T-tube (400-500 ml per day), and normal stools. Prior to her admission to our department, she had undergone a cholecystectomy and T-tube placement following common bile duct exploration for cholelithiasis. Although her serum bilirubin levels initially decreased post-surgery, it rose sharply after T-tube cholangiography. The diagnosis remained unclear until we performed endoscopic retrograde cholangiopancreatography (ERCP), which revealed that the obstructive jaundice was induced by improper T-tube placement. There were few such presentations reported before, and it's particularly unusual to encounter jaundice following T-tube placement. Moreover, diagnosing and treating this condition can be challenging when T-tube drainage appears normal. Thus, our case report provides a unique contribution to the literature on obstructive jaundice.

At present, some common bile duct stones (CBDSs) cannot be removed by conventional endoscopic treatment. Percutaneous transhepatic papillary ballooning and extraction (PTPBE) is a promising treatment for CBDSs. This study aimed to evaluate the feasibility and efficacy of PTPBE for removing CBDSs.

From April 2013 to April 2021, 29 patients with CBDSs underwent PTPBE at The First Affiliated Hospital of Zhengzhou University; their clinical data were retrospectively analyzed. The technical success, clinical success, procedure time, radiation dose, 1-year CBDSs recurrence rate, and incidence of early/late complications were recorded, and white blood cell (WBC) counts and alanine aminotransferase (ALT), C-reactive protein (CRP), total bilirubin (TBIL), and carbohydrate antigen-199 (CA-199) levels were compared before the interventional procedure and 1 month later.

The CBDSs were successfully removed in 29 patients (the CBDSs in 20 patients were resolved once, and in 9 patients, they were resolved twice). The mean procedure time and radiation dose were 56.38±13.56 minutes and 732.07±262.23 miligray (mGy), respectively. The technical and clinical success rates were both 100%. The incidence of early complications (including pancreatitis and bile duct bleeding) and late complications (reflux cholangitis) was 10.34% and 3.45%, respectively. The WBC (both P<0.01), ALT (both P<0.01), CRP (both P<0.01), CA-199 (both P<0.01), and TBIL (both P<0.01) significantly decreased before PTPBE and 1 month later.

PTPBE is a safe and effective alternative solution for elderly patients who cannot undergo or refuse traditional surgical and endoscopic treatments.

While endoscopic retrograde cholangiopancreatography (ERCP) remains the primary treatment modality for common bile duct stones (CBDS) or choledocholithiasis due to advancements in instruments, surgical intervention, known as common bile duct exploration (CBDE), is still necessary in cases of difficult CBDS, failed endoscopic treatment, or altered anatomy. Recent evidence also supports CBDE in patients requesting single-step cholecystectomy and bile duct stone removal with comparable outcomes. This review elucidates relevant clinical anatomy, selection indications, and outcomes to enhance surgical understanding. The selection between trans-cystic (TC) vs trans-choledochal (TD) approaches is described, along with stone removal techniques and ductal closure. Detailed surgical techniques and strategies for both the TC and TD approaches, including instrument selection, is also provided. Additionally, this review comprehensively addresses operation-specific complications such as bile leakage, stricture, and entrapment, and focuses on preventive measures and treatment strategies. This review aims to optimize the management of CBDS through laparoscopic CBDE, with the goal of improving patient outcomes and minimizing risks.

Endoscopic retrograde cholangiopancreatography (ERCP) is technically challenging in patients with Roux-en-Y gastric bypass (RYGB) due to altered anatomy.

To compare the procedural and clinical outcomes of 4 different ERCP techniques in RYGB patients.

Academic tertiary referral center in the United States.

A retrospective cohort study including patients with RYGB anatomy who underwent an ERCP between January 2015 and September 2020. We compared procedural success and adverse events (AEs) rates of balloon-assisted enteroscopy (BAE), gastrostomy-assisted ERCP (GAE), endoscopic ultrasound (EUS)-directed transgastric ERCP (EDGE), and rendezvous guidewire-assisted ERCP (RGA).

Seventy-eight RYGB patients underwent a total of 132 ERCPs. The mean age was 60 ± 11.8 years, with female predominance (85.7%). The ERCP procedures performed were BAE (n = 64; 48.5%), GAE (n = 18; 13.7%), EDGE (n = 25; 18.9%), and RGA (n = 25; 18.9%), with overall procedure success rates of 64.1%, 100%, 89.5%, and 91.7%, respectively. All approaches were superior to BAE (GAE versus BAE, P = .003; EDGE versus BAE, P = .034; RGA versus BAE, P = .011). The overall AE rates were 10.9%, 11.1%, 15.8 %, and 25.0%, respectively. There was no statistical difference in AEs. There were also no differences in bleeding, post-ERCP pancreatitis, and perforation rates between the 4 approaches.

Procedure success was similar between GAE, RGA, and EDGE, but superior to BAE. AE rates were similar between approaches.

We evaluated conventional overnight-stay laparoscopic cholecystectomy, focusing on the preoperative admission day, to assess the feasibility of implementing daycare laparoscopic cholecystectomy, which is currently underutilized in developing and some Asian countries. We retrospectively reviewed elective laparoscopic cholecystectomy data from March 2020 to February 2022 at a 700-bed tertiary hospital in Thailand. Variables included age, sex, body mass index, comorbidities, American Society of Anesthesiologists status, presence of preoperative anesthesiology visit, laparoscopic cholecystectomy indications, additional intraoperative cholangiography, and surgery cancellations. The primary focus was on preoperative treatment and monitoring needs; secondary outcomes included morbidity, mortality within 30 days, and prolonged hospital stay (>48 hours). Statistical analysis was conducted using the Fisher exact test, t-test, and logistic regression. The study included 405 patients. Of these, 65 (16.1%) received preoperative treatment, with 21 unnecessary (over) treatments and six under-treatments. Based on the results, approximately 12.1% (n = 49) of patients may have theoretically required preoperative admission and treatment. Multivariable analysis showed that the increasing of comorbidities was significantly associated with preoperative management (odds ratio [95% Confidence interval]: 7.0 [2.1, 23.1], 23.9 [6.6, 86.6], 105.5 [17.5, 636.6]) for one, two, and three comorbidities, respectively), but factors such as age, obesity, and American Society of Anesthesiologists status were not. The cohort had 4.2% morbidity (2.2% medical complications), with no mortality. Surgery cancellations occurred in 0.5%. In conclusion, on the basis of our data, a small proportion (12.1%) of patients undergoing elective laparoscopic cholecystectomy may require preoperative admissions to receive the necessary treatment, and most (87.9%) preoperative admissions may not provide treatment benefit. The traditional admission approach was safe but required re-evaluation for optimal resource management.

The reasons for the recurrence of common bile duct stones (CBDS) in elderly patients after choledocholithotomy are still unclear. This study aims to establish a prediction model for CBDS recurrence by identifying risk factors.

We conducted a retrospective analysis of 1804 elderly patients aged 65 years and above who were diagnosed to have CBDS and were admitted to Nanjing First Hospital between January 1, 2010, and January 1, 2021. According to inclusion and exclusion criteria, 706 patients were selected for the final analysis. The patients were assigned to two groups according to the presence or absence of CBDS recurrence, and their clinical data were then statistically analyzed. Subsequently, a prediction model and nomogram were developed, evaluating effectiveness using the concordance index (C-index).

Of the 706 elderly patients, 62 patients experienced CBDS recurrence after surgery, resulting in a recurrence rate of 8.8%. The multivariate Cox analysis showed that prior history of cholecystectomy (hazard ratio [HR] = 1.931, 95% confidence interval [CI]: 1.051-3.547, p = 0.034), white blood cell (WBC) count ≥11.0 × 109/L (HR = 2.923, 95% CI: 1.723-4.957, p < 0.001), preoperative total bilirubin (TBIL) level ≥ 36.5 mmol/L (HR = 2.172, 95% CI: 1.296-3.639, p = 0.003), number of stones ≥2 (HR = 2.093, 95% CI: 1.592-5.294, p = 0.001), maximum stone diameter ≥ 0.85 cm (HR = 1.940, 95% CI: 1.090-3.452, p = 0.024), and T-tube drainage (HR = 2.718, 95% CI: 1.230-6.010, p = 0.013) were independent risk factors of CBDS recurrence in elderly patients after choledocholithotomy. A postoperative CBDS recurrence prediction model was constructed with a C-index value of 0.758 (95% CI: 0.698-0.818) and internal validation value of 0.758 (95% CI: 0.641-0.875).

A history of cholecystectomy, WBC count ≥11.0 × 109/L, preoperative TBIL level ≥ 36.5 mmol/L, number of stones ≥2, maximum stone diameter ≥ 0.85 cm, and T-tube drainage are the independent risk factors of CBDS recurrence after choledocholithotomy in elderly patients. Our developed prediction model for CBDS recurrence has good predictive ability and can help predict the prognosis of patients with CBDS.

Endoscopic retrograde cholangiopancreatography (ERCP) combined with laparoscopic cholecystectomy plays an important role in the treatment of cholecystolithiasis combined with choledocholithiasis; however, there is no unified standard for the interval of ERCP before laparoscopic cholecystectomy. We conducted a literature search, data extraction and meta-analysis on this topic. Twelve articles with 1142 patients were included, including 567 patients in the E-laparoscopic cholecystectomy group (laparoscopic cholecystectomy performed within 72 h after ERCP) and 575 patients in the D-laparoscopic cholecystectomy group (laparoscopic cholecystectomy performed 72 h after ERCP). The results showed that: compared with the D-laparoscopic cholecystectomy group, the duration of cholecystectomy was shorter in the E-laparoscopic cholecystectomy group [weighted mean difference (WMD) = -16.18, 95% confidence interval (CI) (-22.27 to -10.08), P  < 0.00001], and the postoperative hospitalization was shorter [WMD = -1.24, 95% CI (-1.98 to -0.50), P  < 0.0001]. There were fewer complications [odds ratio (OR) = 0.25, 95% CI (0.39-0.62), P  < 0.0001], lower conversion rate [OR = 0.39, 95% CI (0.21-0.71), P  = 0.002], lower high sensitivity C-reactive protein at 3 days after surgery [WMD = -8.76, 95% CI (-12.59 to -4.93), P  < 0.00001], and fewer neutrophils in the ampulla of gallbladder specimen [WMD = -4.21, 95% CI (-4.55 to -3.88), P < 0.00001]. Therefore, in the treatment of cholecystolithiasis combined with choledocholithiasis by laparoscopic cholecystectomy within 72 h after ERCP, the degree of inflammation before and after surgery is less, the operation time and hospital stay are shortened, the postoperative complications and the conversion rate are reduced, which is a more appropriate time for surgery.

Laparoscopic common bile duct exploration (LCBDE) and endoscopic retrograde cholangiopancreatography (ERCP) are two methods of retrieving common bile duct (CBD) stones. The best method for CBD stone removal is debatable. The aim of this study was to compare outcomes following LCBDE and/or ERCP, including laparoscopic cholecystectomy.

Data were collected retrospectively for patients undergoing LCBDE and/or ERCP at a single centre from 2008 to 2018. Patients were grouped by intention-to-treat (single-stage LCBDE, pre-operative-, intra-operative-, or post-operative ERCP) and eventual plan (surgical or endoscopic). Outcomes included complication rates (minor Clavien-Dindo 1/2, major Clavien-Dindo 3/4, non-biliary complications) and mortality.

Of 671 patients, 578 patients received LCBDE and 93 patients received ERCP as primary care. Endoscopic clearance had significantly higher complications and mortality compared to surgical clearance. On an intention-to-treat basis LCBDE had the lowest minor-, major- and non-biliary complications, and mortality (5.2%, 6.1%, 2.9% and 0.5%, respectively), whilst pre-operative ERCP the worst (39.6%, 27.1%, 29.2% and 8.3%, respectively) (p=<0.001). LCBDE and postERCP had similar major complications and mortality.

Surgical clearance of CBD stones was potentially safer than endoscopic clearance. Pre-operative ERCP had the worst outcomes. LCBDE and postERCP are likely to have similar short-term patient outcomes.

The management of symptomatic choledocholithiasis remains a controversial issue. At present, the three most common management options for choledocholithiasis include a preoperative endoscopic retrograde cholangiopancreatography with sphincterotomy and stone extraction followed by laparoscopic cholecystectomy, then by either an intraoperative endoscopic retrograde cholangiopancreatography with sphincterotomy or a laparoscopic common bile duct exploration. The purpose of this study was to assess the consequences of the decision to pursue each of these three methods.

We conducted a review of the existing data comparing these three management options. The literature from 2009 to 2021 pertaining to these three methods was reviewed for data on duct clearance, morbidity, mortality, recurrence rate, length of stay, and operative time. Next, we constructed decision trees for each method using a utility score analysis, and these utility scores were used to create a sensitivity analysis based on stone clearance rate.

Laparoscopic cholecystectomy with intraoperative endoscopic retrograde cholangiopancreatography had a utility score of 0.9910, a stone clearance rate of 95.5%, a morbidity of 6.3%, and a mortality of 0.2%. Preoperative endoscopic retrograde cholangiopancreatography with laparoscopic cholecystectomy had a utility score of 0.9629, a stone clearance rate of 85.5%, a morbidity of 13.3%, and a mortality of 0.8%. Laparoscopic cholecystectomy with common bile duct exploration had a utility score of 0.9882, a stone clearance rate of 88.3%, a morbidity of 12.9%, and a mortality of 0.3%.

We have shown that a laparoscopic cholecystectomy with an intraoperative endoscopic retrograde cholangiopancreatography is associated with the best overall outcomes.

Socratic method, which is an educational method to promote critical thinking through a dialogue, has never been practiced in a large number of people at the academic societies.

Modified Socratic method was performed for the first time as an educational seminar using an example case of moderate acute cholecystitis based on the evidence described in Tokyo Guidelines 2018. We adopted a method that Takada had been modifying for many years: the instructor first knows the degree of recognition of the audience, then the instructor gives a lecture in an easy-to-understand manner and receives questions from the audience, followed by repeated questions and answers toward a common recognition.

Using slides, video, and an answer pad, 281 participants including the audience, instructors and moderators came together to repeatedly ask and answer questions in the five sessions related to the case scenario. The recognition rate of the topic of Critical View of Safety increased significantly before vs after this method (53.0% vs 90.3%). The seminar had been successfully performed by receiving a lot of praise from the participants.

This educational method is considered to be adopted by many academic societies in the future as an effective educational method.

The aim of this paper was to report the experience of one-stage LC and LCBDE service within a medium sized acute NHS healthcare trust to demonstrate the feasibility of this treatment modality in terms of safety, quality and effectiveness inside the limitations of the UK's nationalised healthcare system.

All patients undergoing LCBDE at our institution from November 2013 - July 2021 were included in the study. Data were collected from a prospectively maintained institutional database and data points corroborated by electronic patient data on hospital systems.

Three hundred and eleven patients underwent LCBDE. Median age was 68 (range 21-95). Most cases were performed as urgent/emergency (n = 206, 66% vs n = 105, 34% elective). Bile duct stones were diagnosed pre-operatively in 23% of cases (n = 73). Intra-operative diagnosis was made using laparoscopic ultrasound (n = 228, 73%), cholangiogram (n = 44, 14%) or combination of both (n = 31, 10%). Laparoscopic completion rate was 94%. 56% were via choledochotomy and 44% trans-cystic. Incidence of bile leak was 4.2% (n = 13) and the incidence of retained stone within 90 days was 3.9%. Median length of stay was 2 days post-operatively (range 0-62). The rate of mortality was 0.66%.

The data from our study shows that LC and LCBDE is a safe, effective service that can be successfully delivered in the NHS. With the developing specialisation of benign biliary units, we believe that this approach to choledocholithiasis is reproducible and achievable nationally and should be considered first-line in the management of this condition.

Objective: To compare the effectiveness and safety of continuous suture and interrupted suture in Laparoscopic Common Bile Duct Exploration (LCBDE) for choledocholithiasis. Materials and Methods: The data of 125 patients with choledocholithiasis treated with LCBDE in our department from January 2017 to January 2019 were retrospectively collected and divided into two subgroups: the continuous suture group (n = 56) and the interrupted suture group (n = 69). The operation duration, time to suture, intraoperative blood loss, extubation time, hospital stay, total hospitalization expenses, preoperative and postoperative diameters of the common bile duct (CBD), and the occurrence rate of postoperative complications were all compared between the two groups. Results: The operative duration, time to suture, and intraoperative blood loss in the continuous suture group were less compared with those in the interrupted suture group (P < .05). There was no statistical significance between the 2 groups considering extubation time, hospital stay, total hospitalization expenses, and the occurrence rate of postoperative complications (P > .05). The postoperative CBD diameters in both groups were significantly larger than the preoperative CBD diameters (P < .05). Conclusions: The continuous suture technique shortened the operative duration, time to suture, and reduced intraoperative blood loss. It proves to be an effective and safe method in patients diagnosed with CBD stones.

Both one-stage [laparoscopic cholecystectomy (LC) plus laparoscopic common bile duct exploration (LCBDE)] and two-stage [endoscopic retrograde cholangiopancreatography (ERCP) followed by sequential LC] approaches are effective treatment for concomitant common bile duct (CBD) stones and gallstone. Although many studies compared one-stage with two-stage surgical approach for cholecysto-choledocholithiasis, there are very few studies compared the two management strategies for acute cholecystitis (AC) associated with CBD stones.

Between January 2014 and December 2019, patients with concomitant AC and CBD stones proposed to early surgery were retrospectively studied. The patients were scheduled to undergo either the one-stage [LCBDE and LC (LCBDE+LC) were undertaken at the same operation] or two-stage [preoperative ERCP for CBD stone clearance was followed by LC 1-3 days later (pre-ERCP+LC)] procedure. The success rate of complete stone clearance, procedure-related complication, hospital stay, hospitalization charges and later biliary complications were compared between the two groups.

Sixty patients were included in the study, 28 in the one-stage group and 32 in the two-stage group. There was no significant difference in the success rate of complete stone clearance (96.4% vs. 93.8%, P = 1.000), complication rate (10.7% vs. 9.4%, P = 1.000), incidence of pancreatitis (0 vs. 6.3%, P = 0.494) or length of hospital stay (12 ± 5 vs. 11 ± 4 days, P = 0.393) between the two groups.

For patients with concomitant AC and choledocholithiasis proposed to early surgery, both the one-stage (LCBDE+LC) and two-stage (pre-ERCP+LC) approaches were acceptable and broadly comparable in achieving clearance of CBD stones.

This study explored the effects of the timing of laparoscopic cholecystectomy (LC) after endoscopic retrograde cholangiopancreatography (ERCP) on liver function, bile biochemical indices, inflammatory reactions, and cholecysto-choledocholithiasis patient prognoses.

A total of 103 cholecysto-choledocholithiasis patients were stratified into control (CG; n=51; LC at 4-7 d after ERCP) and observation groups (OG; n=52; LC at 1-3 d after ERCP) using a random number table.

The surgical time was shorter and intraoperative blood loss was less in OG than in CG, and the two groups were not statistically different in terms of time to the first passage of gas through anus, length of postoperative hospital stay, conversion rate to laparotomy, and stone-free rate. Four weeks after LC, alanine aminotransferase (ALT), total bilirubin (TBil), albumin (ALB), and glutamyl transpeptidase (GGT) levels declined in both groups, but the difference was not statistically significant. Three days after LC, total bile acid (TBA) levels increased, and cholesterol (CHO), unconjugated bilirubin (UCB), and TBiL levels were reduced in both groups, but were not statistically different (p>0.05). Three days after LC, interleukin (IL)-6, procalcitonin (PCT), and high-sensitivity C-reactive protein (hs-CRP) levels in the serum and bile increased in both groups and were lower in OG. The total incidence of perioperative complications was 1.92% in OG, which was lower than 15.69% in the CG.

For cholecysto-choledocholithiasis patients, LC at 1-3 d after ERCP can shorten surgical times, reduce intraoperative blood loss, improve liver function and bile biochemistry, relieve inflammatory reactions, reduce complications, and improve prognoses.

Recurrence of common bile duct stones (CBDS) is common after surgical stone extraction, but the causes of recurrence are not fully understood. This study aimed to report the experience of treating recurrent CBDS. A total of 106 consecutive cases of recurrent CBDS treated from January 2006 to December 2015 were included. During surgery, the choledochoscopic pass-through test was performed to assess the structure and function of the duodenal papilla. The choledochoscopic pass-through test revealed 62 patients (58.49%) with incomplete closure of the lower end of the common bile duct, and 28 (26.42%) with stenosis at the lower common bile duct. Intra-operative bile bacterial culture was positive in 98 (92.45%) patients. The rate of complete stone clearance was 99.1%. The total recurrence rate of CBDS was 3.13%. The long-term success rate of surgical treatment (excellent and good) reached 92.7% .Duodenal papilla (Oddi sphincter) dysfunction is the main cause of recurrent CBDS. Common bile duct exploration with stone extraction, hilar ductoplasty, and Roux-en-Y hepaticojejunostomy can effectively eliminate the recurrence of CBDS and reduce the incidence of post-hepaticojejunostomy complications. Thus, it is an optimal surgical procedure for recurrent CBDS.

Many studies have failed to demonstrate significant differences between single- and two-staged approaches for the management of choledocholithiasis with concomitant gallstones in terms of post-operative morbidity. However, none of these studies paid specific attention to the differences between the methods of accessing the bile duct during laparoscopy. The aim of this study was to report outcomes of transcystic versus transductal laparoscopic common bile duct exploration (LCBDE) from our experience of over four hundred cases.

Retrospective review of 416 consecutive patients who underwent LCBDE at a single-centre between 1998 and 2018 was performed. Data collected included pre-operative demographic information, medical co-morbidity, pre-operative investigations, intra-operative findings (including negative choledochoscopy rates, use of holmium laser lithotripsy and operative time) and post-operative outcomes.

Transductal LCBDE via choledochotomy was achieved in 242 patients (58.2%), whereas 174 patients (41.8%) underwent transcystic LCBDE. Stone clearance rates, conversion to open surgery and mortality were similar between the two groups. Overall morbidity as well as minor and major post-operative complications were significantly higher in the transductal group. The main surgery-related complications were bile leak (5.8% vs 1.1%, p = 0.0181) and pancreatitis (7.4% vs 0.6%, p = 0.0005). Median length of post-operative stay was also significantly greater in the transductal group.

This study represents the largest single study to date comparing outcomes from transcystic and transductal LCBDE. Where possibly, the transcystic route should be used for LCBDE and this approach can be augmented with various techniques to increase successful stone clearance and reduce the need for choledochotomy.
