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 transanal 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 January2008 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.

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. primary outcome 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 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.
