Single-incision versus conventional laparoscopic cholecystectomy: a meta-analysis

Area of Science:

• Minimally Invasive Surgery
• Gastrointestinal Surgery
• Surgical Outcomes Research

Background:

• Conventional laparoscopic cholecystectomy (CLC) is the standard treatment for gallstones.
• Single-incision laparoscopic cholecystectomy (SICL) aims to reduce surgical invasiveness.
• This meta-analysis compares SICL and CLC outcomes.

Purpose of the Study:

• To compare the safety and efficacy of SICL versus CLC.
• To evaluate key surgical outcomes including adverse events, operative time, and patient satisfaction.
• To determine the cosmetic advantages of SICL.

Main Methods:

• A meta-analysis of randomized clinical trials (RCTs) was conducted.
• Searched Medline, Embase, ISI Web of Knowledge, and Cochrane Library.
• Evaluated outcomes such as adverse events, conversion rate, hospital stay, pain, blood loss, wound length, operative time, and wound satisfaction.

Main Results:

• Five RCTs involving 264 patients were analyzed.
• No significant differences were found in adverse events, conversion rates, hospital stay, blood loss, pain, or wound length.
• SICL demonstrated a significantly longer operative time (WMD 7.72 min) but higher wound satisfaction scores (WMD 1.40).

Conclusions:

• Single-incision laparoscopic cholecystectomy (SICL) shows cosmetic benefits over CLC.
• Operative time is longer for SICL, but it is a safe procedure for appropriate patients and experienced surgeons.
• Further research may explore optimizing SICL techniques to reduce operative time.
