A Case of Crohn's Disease in which Refractory Anal Lesions were Alleviated After Resection of a Small Intestinal Lesion

Abstract

The patient was a 25-year-old male. He developed Crohn's disease at the age of 13 years, and was hospitalized due to multiple perianal abscesses. The primary lesion was located at the terminal ileum, causing marked constriction, and skip lesions were noted in the ascending colon and sigmoid colon. The anal lesions appeared to have been alleviated by conservative treatments, including intravenous hyperalimentation, incision drainage, and drain insertion, but were reactivated by resumption of oral nutrition, and then they began to resis treatments. However, they healed after ileocecal resection of ileus, which was considered to be due to fibrous stenosis caused by treatments. Such reports are uncommon in Japan. We evaluated effects primarilly of the affected intestine on anal lesions.
