Abstract
A 40-year-old woman was admitted to our hospital because of hematochezia on the next day of the onset. Colonoscopy revealed hematoma covered with the stripped mucosa in the sigmoid colon. Four days after the admission, the hematoma was discharged. Immediately after that, barium enema and colonoscopy revealed sharply domarcated girdle ulcer, about 10cm in long, in the sigmoid colon. The conservative treatment including elemental diets was performed. After 10 months the ulcer healed over with little stenosis.
The mucosal abrasion of the large intestine was rarely reported. In our case, the mucosal abrasion might be related to bleeding tendency owing to ticlopidine hydrochloride which she had taken until the onset.
