Resum:	Because of its technical difficulty, totally laparoscopic right colectomy with intracorporeal anastomosis is performed only by a small number of surgeons and most of them use a laparoscopic-assisted technique with extracorporeal anastomosis. This systematic review aims to evaluate differences in outcomes of patients undergoing right laparoscopic colectomy, either with intracorporeal or extracorporeal anastomosis. Electronic databases were searched for studies published between 1991 and 2012. Randomized controlled trials and case-control studies comparing intracorporeal to extracorporeal anastomosis in laparoscopic right colectomy were included in the systematic review. Meta-analytical models were used to evaluate anastomotic leak rate and short-term overall morbidity. Defined primary outcomes of interest were operating time, conversion rate, return of bowel function, anastomotic leak rate, and length of hospital stay. Randomized controlled trials were not found, confirming the paucity of the literature on this topic. Six case-control studies were identified involving 484 patients undergoing right laparoscopic colectomy, 272 with intracorporeal and 212 with extracorporeal anastomosis. Best outcomes seem to be associated with totally laparoscopic right colectomy with intracorporeal anastomosis, especially in terms of return of bowel function, length of hospital stay, and cosmetic results. However, our meta-analysis did not show a significant difference between the two techniques in terms of anastomotic leak rate (OR 0. 98; 95 % CI 0. 30-3. 15) or for short-term overall morbidity (OR 0. 68; 95 % CI 0. 41-1. 12). Comparative analysis of outcomes is in favor of intracorporeal anastomosis. However, the meta-analysis results do not allow us to draw definitive conclusions. Further prospective randomized trials are necessary to confirm our findings.
