SUMMARY OF FIVE YEARS FOLLOW UP COLONOSCOPY ON PATIENTS WITH COLORECTAL POLYPS AND CANCER

From early 1991 to the end of 1995, 3, 620 patients underwent colonoscopy in our hospital. Polyps were foundin a total of 487 cases, 332 of whom had 860 adenomatous polyps. Adenomatous polyposis (adenoma over 100) wasfound in five cases. Colorectal cancer was found in 190 (5. 2 % ) cases, and surgery was performed on 132 of the col-orectal cancer patients, fifteen of whom were diagnosed with early stage cancer (limit within mucosa and submu-cosa). After the follow up program was established, the detection rate of early stage cancer increased to ten times thedetection rate before the follow up program. With the follow up program, 333 adenomas were found in 77 adenomapatients and 74 postoperative colorectal cancer patients. According to the theory that 15 % of all adenomas develop in-to cancerl 179 of the 1, 193 adenomas we have resected might have become cancerous. In conclusion, establishing astandard fonow up program leads to increased and earlier detection of cancerous growths.
