Reversed ileal segment for treatment of ileostomy dysfunction. Clinical application.

Persistent, profuse ileostomy diarrhea developed gradually in a patient over a 12-hour period after proctocolectomy for ulcerative colitis. There was no evidence of ileostomy stenosis or dilation of the ileum proximal to the stoma. He was successfully treated with a reverse ileal segment of 10 cm, and gained 14 to 18 kg. ileostomy output became semisolid and decreased from 1,000 to 2,000 ml/day to 600 ml/day. The transit time changed from 12 minutes to 2 1/2 hours. Antiperistaltic segments of intestine prolong transit time and allow for greater absorption. While most patients with ileostomies are not troubled by severe diarrhea, the small proportion who are may be candidates for a reversed ileal segment.
