INTRODUCTION: The aim of this study was to assess the outcome of patients with indeterminate colitis undergoing double-stapled ileal pouch anal anastomosis.

METHODS: A retrospective review of demographic, disease-related, and outcome variables of all patients undergoing double-stapled ileal pouch anal anastomosis from August 1988 to January 2000 was undertaken. All patients were evaluated using the validated American Society of Colon and Rectal Surgeons Fecal Incontinence Severity Index. Patients with familial adenomatous polyposis, those who had undergone pouch revision or had S-configured pouches, and patients with a follow-up of less than three months were excluded from analysis.

RESULTS: Three hundred ninety-five patients underwent the double-stapled ileal pouch anal anastomosis; of these 303 patients were included for analysis. The mean duration of follow-up was 40 months. Fifty-six (18.1 percent) had a preoperative diagnosis of indeterminate colitis. Postoperatively, indeterminate colitis was diagnosed in 13 (4.3 percent), mucosal ulcerative colitis in 285 (94 percent), and Crohn's disease in 5 (1.6 percent). The overall complication rate was 37.7 percent, 60 percent, and (30.7) percent in patients with mucosal ulcerative colitis, Crohn's disease, and indeterminate colitis, respectively. Postoperative hemorrhage, abscess, and fistula occurred in 2.4 percent, 6.3 percent, and 3.9 percent, respectively, in patients with mucosal ulcerative colitis, and 0 percent, 15.3 percent, and 7.7 percent, respectively, in patients with indeterminate colitis. Small-bowel obstruction occurred in 8.5 percent, 20 percent, and 7.7 percent of patients with mucosal ulcerative colitis, Crohn's disease, and indeterminate colitis, respectively. Pouchitis occurred in 4.6 percent of patients with mucosal ulcerative colitis but in none of the patients with indeterminate colitis. Dysplasia of the anal transition zone was seen in one patient each with mucosal ulcerative colitis and indeterminate colitis. These patients had consistent follow-up and neither showed any sign of evolution to neoplastic disease. None of the patients with indeterminate colitis had a postoperative diagnosis of Crohn's disease during the follow-up period. Functional outcome was comparable in all three patient groups.

CONCLUSION: The outcome of the double-stapled ileal pouch anal anastomosis in patients with indeterminate colitis is similar to that of patients with mucosal ulcerative colitis. Therefore, it is a safe option in patients with indeterminate colitis.
