A study of laparoscopic extraperitoneal sigmoid colostomy after abdomino-perineal resection for rectal cancer.
OBJECTIVE
To established a procedure for laparoscopic extraperitoneal ostomy after abdomino-perineal resection (APR) and study safety aspects and complications.


METHODS
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).


CONCLUSIONS
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.
