Abstract
Follow-up examination following endoscopic polypectomy of the colon has been made for the recent 6 years among 394 polypectomized cases, while 20 cases (5.1%) have experienced as the overlooked and 6 cases (1.5%) as the recurrent. The results were as follows; 1) Out of them 13 polyps were 7 to 9 mm, 7 polyps 10 mm or more in diameter. 2) Their polyps showed 10 sessile, 4 subpedunculated, 3 pedunculated and 3 flat in shape. 3) Ten polyps located in the cecum and ascending colon, 3 in the transverse colon, 2 in the descending colon, 5 in the sigmoid colon and one in the rectum. From the location at point of view, the region near to the hepatic fluxure were commonly overlooked in 13 lesions (65%) containing 5 early colonic carcinomas. 4) Local recurrences after endoscopic polypectomy were recognized in 6 cases. Four of them were removed in piecemeal f asion. All recurrent cases showed villous adenoma histopathologically. Therefore, the patients after endoscopic polypectomy should be followed up by repeated colonoscopy to detect cases of “overlooked”, “recurrence” and “newly arising” colonic polyps.
