Laparoendoscopic single-site cholecystectomy: a safe and reproducible alternative

J Laparoendosc Adv Surg Tech A. 2009 Oct;19(5):599-602. doi: 10.1089/lap.2009.0205.


Background: Laparoscopic cholecystectomy via the three-trocar technique is widely used for symptomatic gallbladder stones. In this article, we describe the initial experience with laparoendoscopic single-site surgery (LESS) cholecystectomy.

Patients and methods: Between February and April 2009, patients referred for cholecystectomy to the General Surgery Unit of our institution who agreed to undergo LESS were included in a prospective study. All operations were performed by the same surgical team that was specially trained in this type of surgery. The umbilicus was the sole point of entry for all patients. The same operative technique was used in all patients. Data of patients undergoing LESS cholecystectomy were compared with those from an uncontrolled group of patients undergoing standard laparoscopic cholecystectomy during the same study period.

Results: The LESS and standard cholecystectomy groups included 19 patients each. LESS was successfully performed in all patients and none required conversion to an open procedure or a conventional laparoscopic cholecystectomy by adding more entry ports. The median operating time of 62 minutes in the LESS group was not significantly different than that in the standard laparoscopic cholecystectomy group.

Conclusions: LESS cholecystectomy was technically feasible, safe, and represents a reproducible alternative to standard laparoscopic cholecystectomy.
