title: Nipple complication caused by a mesenteric GORE-TEX sling reinforcement in a Kock ileal reservoir: report of a case.
abstract: BACKGROUND
  The surgical trend after proctocolectomy at present is to perform a pelvic pouch reservoir with an ileoanal anastomosis. Before that a continent ileal Kock pouch was the procedure of choice, which enabled the patient to collect the intestinal discharge for several hours and avoid involuntary escape of reservoir contents, thus making the wearing of plastic bags unnecessary. Although in the majority of patients an increased life quality can be observed, different complications with a Kock pouch may occur.
  
  
  METHODS
  We present a case of a young female with signs of outlet obstruction several years after a Kock reservoir was performed because of complicated ulcerative colitis. The obstruction was caused by a fecal-coated GORE-TEX sling that had penetrated through the nipple-valve base into the pouch. The mesenteric sling was introduced as a modification of the original Kock procedure to reinforce the efferent ileal segment, thus preventing nipple prolapse. The perforation site was closed with interrupted sutures and an ileostomy was performed.
  
  
  RESULTS
  Three months thereafter, the ileostomy was closed and at a follow-up visit one year later the patient had no complaints and a well-functioning reservoir.
  
  
  CONCLUSIONS
  If continence is desired after definitive ileostomy or if failure of the ileoanal reservoir occurs, a Kock pouch procedure still has a place in the surgical armamentarium of colorectal surgery. Many experts today do not use sling reinforcement maneuvers, and most of these procedures seem to work well without it.
