title: [Unopened colostomy in colorectal surgery: a renewal interest?].
abstract: BACKGROUND
  Anastomotic leak or disruption is a grave complication of colorectal surgery. Protection of an at-risk anastomosis by an upstream open diverting colostomy (OC) reduces this gravity. An unopened upstream loop colostomy is a surgical alternative which may diminish the unpleasant consequences of an open colostomy while maintaining the option of diversion in case of need. The aim of this study is to report the results of this approach and to define its indications.
  
  
  METHODS
  [corrected] We report a retrospective series of 34 cases of unopened diverting loop colostomy to protect an at-risk colorectal anastomosis. Indications for this procedure were stool-laden bowel (59%), low serum albumin (11.5%), local inflammation (11.5%), and very low placed anastomosis (17.5%).
  
  
  RESULTS
  The loop colostomy was eventually opened after surgery in six cases because of anastomotic leakage diagnosed clinically and/or detected by water soluble contrast opacification which was performed routinely on the sixth post-operative day. In all six cases, there was no need for an urgent surgical intervention. In 28 cases, the anastomosis healed without complication and the exteriorized loop was returned to the abdominal cavity seven days after the initial surgery. This was a short, simple procedure with an average operating time of ten minutes. Average hospital stay after returning the unopened colostomy to the abdomen was two days.
  
  
  CONCLUSIONS
  Unopened loop colostomy offers the advantages of protection of a colorectal anastomosis without proper morbidity or mortality, shorter hospitalization, and improved psychological comfort for the patient. It's principal indication is to minimize the risks related to leakage from an at-risk colorectal anastomosis.
