The morbidity of defunctioning stomata

Abstract

Background: The choice of a defunctioning stoma in restorative resection of rectal carcinoma is unclear. Traditionally, the loop colostomy has been preferred.

Methods: All patients with either a defunctioning loop ileostomy or colostomy treated by a single surgeon (MS) were studied. The morbidity of stoma construction and closure, as well as problems experienced in the intervening period, were entered on a database.

Results: No significant difference in the morbidity of closure was noted when loop ileostomy was compared to loop colostomy. Although a trend favouring loop ileostomy was noted when interval morbidity was examined, this difference was not statistically significant.

Conclusions: Loop colostomy and ileostomy are both effective in defunctioning the distal colon following a restorative resection for rectal carcinoma. There is some morbidity associated with both but when a stoma is constructed, loop ileostomy is preferable. The loop ileostomy is generally easier to manage and is not associated with a greater rate of complications (in its construction and closure) than the loop colostomy.
