The authors conducted a retrospective study of 337 patients who underwent angiography for chronic gastrointestinal bleeding from December 1991 to October 1996. Seven cases (65-74 years old) were diagnosed as having colon cancer. Colonoscopy and/or barium enema were performed more than once in 7 patients and the results showed normal. All 7 patients were found to have abnormalities by angiography and they were diagnosed as colon cancer and laparotomy.
