Analysis of the Efficacy of Medical Treatment and the Cumulative Operation Rates of Behcet's Colitis According to the Colonoscopic Classification / 대한소화기내시경학회지

ABSTRACT

BACKGROUND/AIMS: The lesions of Behcet's colitis showed aphthoid or punched-out ulceration, but the macroscopic types of lesions have not been defined. The aim of this study was to predict the clinical outcome of patients with Behcets colitis according to colonoscopic findings. METHODS: We retrospectively reviewed the medical records and colonoscopic photographs of 50 patients with Behcet's colitis. Colonoscopic findings were categorized according to three types volcano-, geographic- and aphthous-type. The efficacy of medical treatment was assessed by follow-up colonoscopy or double-contrast barium enema 4 to 8 weeks after treatment and recurrence of the lesions was evaluated during the follow-up period. Cumulative operation rates were obtained by the Kaplan-Meier method. RESULTS: Macroscopic types of colonic ulcers revealed 25 out of 50 (50%) patients with volcano-type, 11 (22%) with geographic-type, and 14 (28%) with aphthous-type lesions. Complete remission rates by medical treatment and operation rates in volcano-type ulcerations were 6 of 25 (24%) and 13 of 25 (52%), geographic-type 8 of 11 (73%) and 1 of ll (9%), and aphthous-type 9 of 14 (64%) and 2 of 14 (14%), respectively. The recurrence rate in volcano-type ulcerations was 9 of 19 (47%), geographic-type 1 of 9 (11%) and aphthous-type 1 of 11 (9%), CONCLUSIONS: Volcano-type ulcerations in Behcets colitis showed less favorable response to medical treatment and more episodes of operation and recurrence than geographic- and aphthous-type ulcerations.
