Single-incision laparoscopic cholecystectomy: a systematic review

Article Overview
A trend toward even more minimally invasive laparoscopic approaches has led to techniques of single-incision and natural orifice laparoscopic surgery. This article is a systematic review of the literature which examines the feasibility, safety, and results of single-incision laparoscopic cholecystectomy (SILC), and defines, if possible, the limitations of this technique.

Methods
A literature search confined to studies published in English and German was performed using the electronic database of Medline through mid-February 2010. Studies were considered for inclusion provided the following criteria were fulfilled: (1) The study included ten or more patients who underwent SILC, (2) No additional incisions besides the umbilical were performed, (3) Analytical conversion and complication data were reported.

Data from 29 studies with 1,166 patients were reviewed. The chi-square test (x2) was used to evaluate the differences in success and complication rates according to demographic and operative study data.
