Popis: PURPOSE: We studied patients with Crohn’s disease affecting the colon to characterize disease behavior and to determine whether such patients might be candidates for sphincter-sparing surgery. METHODS: Ninety-two consecutive patients with Crohn’s colitis were studied prospectively. Mean follow-up after diagnosis was 82 (range, 6–291) months. Parameters that were evaluated included previous surgery for Crohn’s disease, granulomatous vs. nongranulomatous disease, extent of colonic involvement, and presence or absence of extracolonic disease. The clinical course of the disease and postoperative outcome were evaluated. The outcome of Crohn’s colitis patients who underwent ileal pouch-anal anastomosis for presumed ulcerative colitis was also evaluated. RESULTS: There were 39 patients with granulomatous colitis and 53 patients without granulomas. There was no statistical difference in the age of diagnosis or presence of small-bowel (23 vs. 27 percent), ileocolic (34 vs. 30 percent), or perineal (36 vs. 22 percent) disease in these patients. At initial presentation, 88 percent of patients with pancolitis had colitis alone without other sites of intestinal disease compared with only 37 percent of patients with segmental colitis (P < 0.001). Kaplan-Meier analysis showed that patients with granulomas and patients with segmental colitis at presentation have a significantly higher recurrence when compared with patients without granulomas and patients with pancolitis (P < 0.03). Thirteen patients without granulomatous disease and eight with granuloma underwent ileal pouch-anal anastomosis. Seven patients (3 with granuloma, 4 without granuloma) had a recurrence of Crohn’s disease in the ileal pouch; 2 required pouch removal and permanent diversion for fistulizing disease in the ileal pouch and 5 were successfully treated conservatively without surgery. CONCLUSION: The presence of granulomas and segmental involvement of the colon in patients with Crohn’s colitis may reflect a more virulent clinical course. Ileal pouch-anal anastomosis may be considered as an option in select patients with Crohn’s colitis without small-bowel or perianal disease. Based on our data, patients with nongranulomatous pancolitis may be better candidates for sphincter-sparing surgery.
