Outcome of patients with indeterminate colitis undergoing a double-stapled ileal pouch-anal anastomosis.

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.

Trends in preparation for colorectal surgery: survey of the members of the American Society of Colon and Rectal Surgeons.

The utility of antibiotic and mechanical preparation for colorectal surgery is controversial, and numerous different regimens are used. The aim of this study was to detect trends in preparation for surgery among American colon and rectal surgeons. Members of the American Society of Colon and Rectal Surgeons practicing in the United States were surveyed with a postal questionnaire regarding their routine preparations for colon and rectal surgery. Five hundred fifteen (40%) of the 1295 questionnaires sent were returned. Eighty-one per cent of the respondents had completed an accredited colorectal training program, and the average experience in practice was 13.7 (+/- 8.7) years. Half of the surgeons felt that prophylactic oral antibiotic is essential, 41 per cent felt it was doubtful, and 10 per cent considered oral prophylaxis unnecessary. Despite these statements 75 per cent of the surgeons routinely utilized oral antibiotics (96% of them used a combination of two drugs), 11 per cent used them selectively, and only 13 per cent omitted oral prophylaxis from their practice. Similarly although the usefulness of intravenous antibiotics was questioned by 11 per cent of the surgeons 98 per cent routinely used them. The average number of postoperative doses was two (+/- 1.9). Although 10 per cent of the surgeons questioned the importance of mechanical preparation more than 99 per cent routinely used it. Forty-seven per cent of the surgeons used sodium phosphate, 32 per cent used polyethylene glycol, and 14 per cent alternated between these two options. We conclude that although the use of oral antibiotic prophylaxis for colorectal surgery is controversial among surgeons it is still routinely practiced by 75 per cent. Intravenous antibiotic prophylaxis and mechanical cleansing, however, are still a dogma and almost invariably used. There is a trend toward the use of a shorter course of postoperative intravenous antibiotics and the use of sodium phosphate for mechanical cleansing.
