PurposeThe aim of this systematic review was to compare intracorporeal (IA) versus extracorporeal anastomosis (EA) after laparoscopic right hemicolectomy for cancer.MethodsThe meta-analysis was conducted following all aspects of the Cochrane Handbook for systematic reviews and Preferred Reporting Items for Systematic Reviews and Meta-analysis statement. Studies published from 2009 to 2012 that compare IA and EA after laparoscopic right hemicolectomy were identified. The included non-randomized studies were assessed for their methodological quality using the revised and modified grading system of the Scottish Intercollegiate Guidelines Network. Intraoperative, early postoperative, and postoperative recovery outcomes were compared using weighted mean differences and odds ratios.ResultsFive non-randomized controlled trials published between 2009 and 2011, comprising 425 patients, were included in this analysis. IA was associated with significant faster bowel movement, faster first flatus, shorter time to solid diet, decreased use of analgesics, and shorter duration of the hospital stay. No differences were observed for nasogastric tube reintroduction rate, operative time, incision length, number of nodes harvested, intraoperative complications, mortality, non-surgical site complications, surgical site complications (anastomotic leakage, anastomotic bleeding, wound infection, ileus), reintervention, and readmission rate.ConclusionsEven when the limitations are taken into account due to the observational nature of the included studies, the results suggest that the IA after laparoscopic right hemicolectomy for cancer results in better postoperative recovery outcomes, such as shorter hospital stay, faster bowel movement recovery, faster first flatus, faster time to solid diet, and lesser analgesic usage.
