Proctocolectomy and pelvic pouch--is a diverting stoma dangerous for the patient?
OBJECTIVE
A diverting loop ileostomy was previously considered mandatory for minimizing the effects of septic complications in pelvic pouch surgery. During the past decade there has been a trend towards omission of the loop ileostomy without obvious signs of increased numbers of pouch complications or impaired long-term function. The aim of the present study was to evaluate the risk of complications associated with the construction and closure of the loop ileostomy itself.


METHODS
Complications following diverting loop ileostomies in 143 patients subjected to restorative pelvic pouch surgery during the period 1983-97 were studied retrospectively by evaluation of case records.


RESULTS
In the period between discharge after pelvic pouch surgery and closure of the loop ileostomy, 20 (14%) patients were hospitalized because of excessive stoma flow and 19 (13%) patients were treated for other surgical complications, of whom 10 (7%) required surgical intervention. In the early postoperative period (within 30 days) after closure of the loop ileostomy, 18 (13%) patients suffered complications necessitating surgery. Another 12 (8%) patients were hospitalized because of intestinal obstruction that could be treated conservatively.


CONCLUSIONS
The proportion of complications associated with diverting loop ileostomies in pelvic pouch surgery was considerable. A randomised controlled multicentre study is ethically defensible and is recommended.
