Single-incision versus four-port laparoscopic cholecystectomy in an ambulatory surgery setting: A prospective randomised double-blind controlled trial

Background Single-incision laparoscopic cholecystectomy (SILC) can be done as a day-case procedure and may have advantages over conventional laparoscopic cholecystectomy (LC). We present the results of our study looking at post-operative pain and post-operative recovery time. Methods This was a single-institution randomised double-blind controlled trial. Seventy-three patients with symptomatic cholelithiasis were randomized to SILC (n = 37) or LC (n = 36). The primary endpoint was to compare post-operative pain. We also compared surgical time, procedural difficulty, adverse events, additional ports used and conversion rate, success of day surgery process, return to work, aesthetic satisfaction, quality of life and 4-year incisional hernia rate. Results In the SILC group, post-operative analgesic requirements were lower on day 7, there was an earlier return to work and cosmetic satisfaction was significantly higher. The SILC procedure presented a higher technical difficulty. Operative time, surgical complications, post-operative pain, success of the day-case process, return to normal activity, quality of life scores and incisional hernia rates were similar for both the procedures. Conclusions SILC has advantages over LC in terms of late post-operative analgesic requirements and aesthetic results; however, it is technically harder to perform. There was no benefit in terms of day surgery outcomes.
