Single-incision laparoscopic appendectomy (SILA) is one of the most commonly performed single port surgeries in the world. However, there are few publications documenting a young resident’s experience. The purpose of this study is to investigate clinical outcomes of SILA performed by a surgical trainee and to evaluate its feasibility and safety compared with conventional three-port laparoscopic appendectomy (TPLA) when performed by a surgical trainee and SILA by surgical staff.

Between September 2014 and August 2015, clinical data were retrospectively collected for SILA and TPLA cases performed at Chung-Ang University Hospital. Three surgical residents who have assisted at least 50 cases of TPLA and 30 cases of SILA performed by gastrointestinal surgery specialists performed the surgeries. The indication of SILA by surgical trainees was noncomplicated appendicitis with no comorbidity.

In total, 47 patients underwent SILA by surgical residents, 98 patients underwent TPLA by surgical residents and 137 patients underwent SILA by surgical staff. In comparing SILA and TPLA performed by surgical residents, the mean age was younger (26 vs. 41 y, P<0.005) in the SILA group, the operative time (47.2 vs. 61.5 min, P<0.010) and hospital stay (2.3 vs. 2.7 d, P=0.003) were shorter in SILA group. In the SILA group, 2 cases of postoperative fluid collection (5.7%) occurred, necessitating antibiotic treatment. In TPLA group, 1 postoperative abscess occurred, requiring drainage. When comparing SILA performed by surgical residents and SILA performed by surgical staff, there were no significant differences in operation time, and postoperative complications.

Surgical residents safely performed SILA with good postoperative outcomes after short learning curve.

The aim of the study was to describe the technique of two-trocar laparoscopic appendectomy and compare the outcome between two- and three-trocar techniques in children.

All children who underwent laparoscopic surgery for suspected appendicitis from 2006 to 2014 in a center for pediatric surgery were included in the study. Converted surgeries and patients with appendiceal abscess or concomitant intestinal obstruction were excluded. A total of 259 children underwent appendectomy with either two (35 %) or three (65 %) laparoscopic trocars according to the surgeons’ preference and intraoperative judgment. Patient demographics, clinical symptoms, surgery characteristics, and complications were reviewed.

The mean age of the children was 10.4 years (range, 1–14 years). The mean follow-up time was 41.2 months (SD ± 29.2). No significant differences in age, gender, weight, or signs and symptoms were found between the two- and three-trocar groups. The mean surgery time was significantly shorter in the two-trocar group (47 min) than in the three-trocar group (66 min; p < 0.001). The rates of surgical complications were 2 % vs. 4 %, (p = 0.501), and the rates of postoperative complications were 0 % vs. 5 % (p = 0.054), in the two- and three-trocar groups. The overall incidence of postoperative wound infection was low (<1 %) and did not differ between groups.

Two-trocar laparoscopic appendectomy seems to be a safe and feasible technique with a low rate of postoperative wound infections. The present findings demonstrate that when the two-trocar technique could be applied, it is a good complement to the conventional three-trocar technique.

With the cooperation of surgeons and the engineering division of the company Bhio supply^© (Esteio-RS, Brazil), a permanent single port was developed.

An experimental study assessed the safety and efficacy of the device using a swine laparoscopic appendectomy model (right salpingo-oophorectomy).

Experimental randomised study.

A total of 20 pigs were randomised for the conventional laparoscopic (CL) three-trocar technique or the single Centry port (CPort) with two working channels, aided by a transparietal thread. Operative times, surgical complications, CO₂ use, and pneumoperitoneal pressure were checked. Pressure and chromopertubation tests assessed the ligatures.

For quantitative outcomes, the Fisher's exact test analysed the samples to compare the surgeons in each group, the ANOVA test for parametric data (volume and pressure) and the Student's t-test for analysis of the fascial incision length. The binaries and isolated occurrence events were described in percentages.

For all cases, pneumoperitoneum was maintained. The CPort group, however, resulted in higher CO₂ use (26.18 l; standard deviation [SD] ± 11.09) than CL group (5.69 l; SD ± 2.44) (P < 0.01). The mean pressure in CPort group (6.604 mmHg, SD ± 1.793) was comparatively lower than in CL group (7.382 mmHg, SD ± 1.833) (P = 0.363). There was no statistical difference between operative times, ligature safety or adverse surgical events between the different groups and surgeons.

The surgical technique used with the single port showed no differences in safety and efficacy. Though it does require more CO₂ use, its working dynamics did not lead to increased operative times. The results were similar between the two surgeons in the study, suggesting that they can be reproduced.

Single incision laparoscopy (SIL) has become an emerging technology aiming at a further reduction of abdominal wall trauma in minimally invasive surgery. Available data is encouraging for the safe application of standardized SIL in a wide range of procedures in gastroenterology and hepatology. Compared to technically simple SIL procedures, the merit of SIL in advanced surgeries, such as liver or colorectal interventions, compared to conventional laparsocopy is self-evident without any doubt. SIL has already passed the learning curve and is routinely utilized in expert centers. This minimized approach has allowed to enter a new era of surgical management that can not be acceded without a fruitful combination of prudent training, consistent day-to-day work and enthusiastic motivation for technical innovations. Both, basic and novel technical specifics as well as particular procedures are described herein. The focus is on the most important surgical interventions in gastroenterology and aims at reviewing the current literature and shares our experience in a high volume center.
