Abstract
A 71-year old man was admitted to our hospital with a chief complaint of constipation. The patient was diagnosed as having a villous rectal tumor 8.5 cm in maximal diameter by proctoscopy and barium enema examination. Endoscopic treatment was selected because he had been taking long-term oral steroids for rheumatoid arthritis and had a history of diabetes mellitus. A total of 17 endoscopic treatment, i. e., removal of the tumor and mucosal cautery under endoscopic control, were conducted over a 22month period. These treatments revealed a pathologically definitive diagnosis of adenocarcinoma in villous adenoma. During the 3 years from the final treatment, the patient had no evidence of recurrence. In the absence of invasive cancer, endoscopic treatment will become the therapeutic option of choice for the treatment of villous tumor of the rectum, irrespective of tumor size.
