A study of laparoscopic extraperitoneal sigmoid colostomy after abdomino-perineal resection for rectal cancer

摘要

>Objective: To established a procedure for laparoscopic extraperitoneal ostomy after abdomino-perineal resection (APR) and study safety aspects and complications.>Method: From July 2011 to July 2012, 36 patients with low rectal cancer undergoing APR were included in the study and divided into extraperitoneal ostomy group (n = 18) and intraperitoneal ostomy group (n = 18). Short- and long-term complications were compared between the two groups. All patients were followed up and the median duration was 17 months (range: 12–24).>Results: The rates of short-term complication related to colostomies were comparable between the two groups, except the rate for stoma edema was higher in the extraperitoneal group (33.3% vs 0%; P = 0.008). In the intraperitoneal ostomy group, two patients developed stoma prolapse, one had stoma stenosis, and two had parastomal hernia. In contrast, no long-term complications related to colostomies occurred in the extraperitoneal ostomy group. The rate of long-term complication was lower in the extraperitoneal ostomy group (0% vs 22.2%; P = 0.036).>Conclusion: The laparoscopic extraperitoneal ostomy is a relatively simple and safe procedure, with fewer long-term complications related to colostomy. However the follow-up period was not too long and needs to be extended.
