Effect of extraperitoneal colostomy after abdominoperineal radical resection of rectal cancer on incidence of parastomal hernia and defecation function

Abstract

Objective To investigate the effect of extraperitoneal colostomy after abdominoperineal radical resection of rectal cancer on parastomal hernia and defecation function. Methods The subjects of the study were 78 patients undergoing abdominoperineal radical resection in Guangyuan City Central hospital from January 2016 to June 2017. Of these, 40 patients undergoing extraperitoneal colostomy were in the observation group, and 38 patients undergoing intraperitoneal colostomy were in the control group. The patients in the two groups received full nursing care during perioperative period. The surgical indexes, postoperative complications and defecation function between the two groups were compared. Results The amount of intraoperative bleeding and length of hospital stay in the observation group were (104.24±39.08) ml and (15.62±3.10) days, respectively, significantly different from that in the control group (120.46±47.35) ml and (17.20±2.95) days (P 0.05). The excellent and good rate of defecation function in the observation group was significantly higher than that in the control group (67.50% vs 34.21%, P 0.05). Conclusion Extraperitoneal colostomy after abdominoperineal radical resection of rectal cancer can significantly reduce the incidence of perioperative parastomal hernia and promote the recovery of defecation function. The overall curative effect is better than that of intraperitoneal colostomy.
