Colonic J-pouch versus Baker type for rectal reconstruction after anterior resection of rectal cancer.

OBJECTIVE. There is no consensus regarding reconstruction type after anterior resection for rectal cancer. We conducted a meta-analysis of relevant randomized controlled trials (RCTs) to compare outcomes of colonic J-pouch (CJlP) and side-to-end anastomosis (STEA) after anterior resection of rectal cancer. METHODS. Electronic databases were searched in January 2013, with six RCTs selected for further analysis, for a total of 451 patients (229 CJP, 222STEA). Outcome measures included surgical, physiologic, and functional outcomes, as well as postoperative complications. The odds ratio (OR) was used in the statistical analysis; in other circumstances, qualitative descriptions were performed. RESULTS. As far as surgical outcomes and postoperative complications, there was no difference between groups. While functional outcomes were substantially impaired, this was similar between groups. CJP demonstrated better function in the early postoperative period. No difference was seen between groups with regards to physiologic outcome. CONCLUSION. CJP and STEA are comparable when choosing the type of reconstruction for restoration of bowel continuity in anterior resection for rectal cancer.
