The present report analyzed a series of 767 polyps from 15,000 cases who wore undogone colonos- copy or sigmoidoscopy at the dept, of internal medicine, Seoul National Universily Hospital from June 1976 to Dec. 1989. The results are as follows. 1) The prevalence of colorectal polyp was 5,1% (767 cases out of 15,000 cases) and increased from 1976 to 1989. 2) The most common symptom was anal bleeding (27%). 3) The 43 cases out of 203 cases (21%) revealed a positive finding in occult blood examination of stool, and 88 cases out of 158 cases (55%) turned out to have polyps in colon study.
4) The most common histologic type of polyp was adenomatous (49%) and the most common gross iype was Yamada type II (30.%). 5) Eleven cases out of 30 cases (36.9%) whose polyps were over 2 cm in diameter were villous adenoma, and 4 cases out of 11 cases (36%) had a foci of cancer. Ten cases out of 245 cases (4%) whose polyps wore under 1 cm in diameter were villous adenoma, and the foci of cancer were not seen. These figure suggest that as polyps grow, the risk of villous adenoma and cancer increase. 6) When we compared endoscopic findings with histologic types in polypectomized specimens, 9 cases (64%) out of 14 cases were diagnosed as hyperplastic polyp by only endoscopy, and 68 cases (91%) out of 75 cases were diagnosed as adenomatose polyp by only endoscopy. 7) Six cases (4.4%) out of 135 cases in tubular, four cases (16.6%) out of 24 cases in villotubular, four cases (19%) out of 21 cases in villous adenoma, were colorectal cancer with polyp remnant, respectively. The annual prevalence of colorectal polyp increased and endoscopy was superior to Barium enema in diagnosing colorectal polyps. For prevention of colorectal cancer, more effort should be done in detecting and eradicating colorectal polyps.
