Objective:Anastomotic leakage(AL)is one of the serious complications after anterior resection for rectal cancer.Defunctioning stoma(DS)is one of the most widely used approaches to prevent it;however,the effect of DS on the occurrence of AL remains controversial.This study aimed to investigate risk factors of AL and assess the effect of DS after anterior resection for rectal cancer patients.Methods:A retrospective analysis was conducted for the data of 1840 patients who underwent anterior resection for rectal cancer from January 2014 to December 2019.Results:The results showed the overall AL incidence was 7.5％.Multivariate analyses revealed that males[odds ratio(OR)1.562]and T3-T4 stage(OR 1.729)were independent risk factors for all patients.After propensity score matching analysis,the AL incidence was 14.1％in the group with no DS and 6.4％in the DS group(P＜0.001).The clinical AL(grade B+grade C)incidence was 12.4％in no DS group and 4.6％in the DS group(P＜0.001).Conclusion:The study suggested that males and T3-T4 stage were independent risk factors of AL.In addition,DS could reduce the rate of symptomatic AL.
