Rectal stenosis is usually caused by neoplasms, compression from adjacent organ and tissue, inflammatory bowel disease, sexually transmitted disease, and proctitis due to radiation, ischemia, abuse of suppositories, and rectal intercourse. Rectal stenosis due to nonspecific inflammation is quite rare. Here a patient with such rectal stenosis is presented. A 61- year-old male had distress of evacuation for one year. The symptom gradually deteriorated until the presence of rectal stenosis was indicated in May 1995. Colostomy was established at the sigmoid colon in July 1995. Since a definite diagnosis could not be made even by repeated mucosal and submucosal biopsy and a malignant disease could not be denied, abdominoperineal resection was performed two months after the first operation. In the resected specimen, narrowing of the lower rectum, 9.5cm in length, was noted with smooth mucosa and thickened wall. A histological examination showed thick fibrosis and dense infiltration of chronic inflammatory cells in the submucosal and proper muscle layers. The diagnosis was stenosis due to nonspecific inflammation. To the best of our knowledge, there has been no previous report of such a patient in Japan.
