Ileoproctostomy is preferred over ileoanal pull-through in patients with indeterminate colitis

Abstract

A 15-year retrospective review was undertaken to evaluate the operative outcomes of patients with indeterminate colitis who were referred for rectal-sparing operations. Review of 95 consecutive patients operated for ulcerative colitis (UC) or indeterminate colitis (IC) revealed characteristics of IC in 13 patients. In the group as a whole, there were 45 females and 50 males; the average age was 33. A total of 64 patients had ileoanal pull-through (IAA). Analysis revealed that four of these patients had IC revealed by findings before operation in three patients and following the first stage of operation in one patient. Three of these four patients have subsequently required permanent ileostomy. Six patients who underwent IAA have subsequently demonstrated signs and symptoms of Crohn's disease (CD). All six have subsequently required ileostomy. Overall 10 patients with CD underwent IAA, and nine have required permanent ileostomy. Fourteen patients had ileorectal anastomosis (IRA) for UC or IC. IRA was performed for patients with IC in nine cases, and five patients with UC elected this operative option. Indications for IRA in patients with UC included obesity, 2; mental retardation, 1; advanced age, 1; and patient preference, 1. Of the patients with IC who underwent IRA, two have subsequently shown signs and symptoms of Crohn's disease. Overall, 14 of 14 patients who had IRA still have functioning IRA. None has required ileostomy. The poor results in patients with UC or IC subsequently shown to have CD have caused us to change our operative approach in patients with any question in the diagnosis of UC.(ABSTRACT TRUNCATED AT 250 WORDS)
