Can trans-anal reinforcing sutures after double stapling in lower anterior resection reduce the need for a temporary diverting ostomy?

초록

AIM: To evaluate trans-anal reinforcing sutures in low anterior resection using the double-stapled anastomosis technique for primary rectal cancers performed at a single institution. METHODS: The data of patients who received trans-anal reinforcing sutures were compared with those of patients who did not receive them after low anterior resection. Patients who underwent laparoscopic low anterior resection and the double-stapled anastomosis technique for primary rectal cancer between January 2008 and December 2011 were included in this study. Patients with no anastomosis, a hand-sewn anastomosis, high anterior resection, or preoperative chemoradiation were excluded. The primary outcomes measured were the incidence of postoperative anastomotic complications and placement of a diverting ileostomy. RESULTS: Among 110 patients, the rate of placement of a diverting ileostomy was significantly lower in the suture group (SG) compared with the non-suture control group (CG) [SG, n = 6 (12.8%); CG, n = 19 (30.2%), P = 0.031]. No significant difference was observed in the rate of anastomotic leakage [SG, n = 3 (6.4%); CG, n = 5 (7.9%)]. CONCLUSION: Trans-anal reinforcing sutures may reduce the need for diverting ileostomy. A randomized prospective study with a larger population should be performed in the future to demonstrate the efficacy of trans-anal reinforcing sutures. (C) 2013 Baishideng. All rights reserved.
