Transumbilical single-incision laparoscopic cholecystectomy: long-term review from a single center

Low long-term incidence of incisional hernia after cholecystectomy: A systematic review with meta-analysis

BACKGROUND

Various surgical approaches are available for cholecystectomy, but their long-term outcomes, such as incidence of incisional hernia, are largely unknown. Our aim was to investigate the long-term incidence of incisional hernia after cholecystectomy for different surgical approaches.

METHODS

This systematic review and meta-analysis was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A protocol was registered on PROSPERO (CRD42020178906). Three databases were searched for original studies on long-term complications of cholecystectomy with n > 40 and follow-up ≥6 months for incisional hernia. Risk of bias within the studies was assessed using the Newcastle-Ottawa Scale and the Cochrane "risk of bias" tool. Meta-analysis of the incidence of incisional hernia after 6 and 12 months was conducted when possible.

RESULTS

We included 89 studies. Of these, 77 reported on multiport or single-incision laparoscopic cholecystectomy. Twelve studies reported on open cholecystectomy and 4 studies on robotic cholecystectomy. Weighted mean incidence proportion of incisional hernia after multi-port laparoscopic cholecystectomy was 0.3% (95% confidence interval 0-0.6) after 6 months and 0.2% after 12 months (95% confidence interval 0.1-0.3). Weighted mean incidence of incisional hernia 12 months postoperatively was 1.5% (95% confidence interval 0.4-2.6) after open cholecystectomy and 4.5% (95% confidence interval 0.4-8.6) after single-incision laparoscopic cholecystectomy. No meta-analysis could be conducted for robotic cholecystectomy, but incidences ranged from 0% to 16.7%.

CONCLUSION

We found low 1-year incidences of incisional hernia after multiport laparoscopic and open cholecystectomy, whereas risks of incisional hernia were considerably higher after single-incision laparoscopic and robotic cholecystectomy.

Analysis of post-operative complication in single-port laparoscopic cholecystectomy: A retrospective analysis in 817 cases from a surgeon

BACKGROUND

Single-port laparoscopic cholecystectomy (SPLC) is a new advanced technique in laparoscopic surgery which has many benefits according to previous reports. The purpose of this study was to present personal experiences with SPLC in >800 cases performed by a surgeon to evaluate the safety and feasibility of this procedure.

MATERIALS AND METHODS

A retrospective review of 817 cases of SPLC was conducted. All patients had received elective SPLC by a surgeon in our centre during March 2009-August 2015. Our review suggests patients' character, peri-operative data and post-operative outcome.

RESULTS

Three hundred and ninety-eight men (48.7%) and 419 women (51.3%) with an average age of 48.3 years had received SPLC. Their mean body mass index (BMI) was 23.75 kg/m2. The mean operating time took 46.9 min (19-130). Seventy-nine cases (9.7%) needed additional port during operation. BMI, age and previous abdominal surgical history did not affect conversion to multiport surgery. Bile spillage during operation occurred in 73 cases (8.9%). There were 4 cases of open conversion because of bleeding (2 cases, 0.2%) and common bile duct (CBD) injury (2 cases, 0.2%). Mean duration of hospital stay was 2.36 days. We have experienced 38 cases (4.7%) of post-operative complication: 8 cases (1.0%) of major one and 30 cases (3.7%) of minor one. Major complication occurred in 3 cases (0.4%) of retained CBD stone, 3 cases (0.4%) of cystic duct leakage needed endoscopic retrograde cholangiopancreatography and 2 cases (0.2%) of CBD injury needed reoperation. Most minor complications were wound infections that have healed after conservative treatment. There were no post-operative mortalities.

CONCLUSION

SPLC is a safe and practicable technique. With surgical experience, criteria and area of SPLC can be broadened. SPLC is occupying a greater domain of a laparoscopic cholecystectomy.

Is Single-incision Laparoscopic Cholecystectomy Feasible for Acute Cholecystitis? A Consecutive Study of 60 Cases

The feasibility of single-incision laparoscopic cholecystectomy (SIL-C) for patients with acute cholecystitis were evaluated based on the timing of operation after onset of symptoms. Sixty patients with acute cholecystitis who underwent SIL-C were divided into 2 groups according to the timing of operation: group E included 23 patients who underwent SIL-C within 72 hours, and group O included 37 patients who underwent SIL-C later. There were no statistical differences between group E and group O in clinicopathologic characteristics. Group E demonstrated significantly shorter operating time and less blood loss than group O. Although the incidences of additional port(s) requirements were not significantly different, 8 patients in group O required open conversion, indicating significantly higher rate. As group E demonstrated favorable surgical outcomes compared with group O, SIL-C for acute cholecystitis seems to be a feasible therapeutic procedure when performed within 72 hours as updated Tokyo Guidelines recommended.
