Background
/Aims: Colonic polyps are premalignant lesion, whose removal is important for the prevention of colon cancer. Methods: A series of 116 patients (195 polyps) who undergone colonoscopic polypectomy at Chung Nam National University Hospital from March 1994 to Feb.1997 were analyzed. Results: 1) The ratio of males and females was 81:35, with the average age being in the 60's. 2) Colorectal polyps were found at the rectum (39.5%), sigmoid colon (35.9%). The size of the polyps was less than 0.6 cm in diameter (44.6%), between 0.6 and 1.0 cm (27.7%), between 1.1 and 2.0 cm (22.6%). The number of polyp was single polyp (59.5%). According to the Yamada classification, type III was the most common (43.1%). 3) Histopathologic findings were as follows. Tubular adenomas (58.6%), LSPs was in 3 cases, and malignant changed polyps in 14 case. 4) The malignantly changed polyps peaked in those in their 70's, had sizes ranging between 1.1 and 2.0 cm. Histopathologic finding were villous adenomas (50.0%), tubular adenomas (13.2%), LSPs (33.3%) in orders. Conclusion: Although the prevalence of cancer of villous adenomas and LSP was higher than other polyps, the size of the adenomas, their numbers do not seem to influence the malignancy rate in this report.
