ABSTRACT

background: Almost all colorectal cancers arise from adenomatous polyps. Colonoscopic polypectomy is the best way to remove these lesions as a consequence avoids the progression to cancer. Objetive: To know the different histological types of colorectal polyps, frequency and identify the main complication during colonoscopic polypectomy. Material and methods: Retrospective analysis was made about endoscopic findings from 4689 colonoscopies, from 1988 to 2003, a record was made with the patients with colorectal polyps who had colonoscopic polypectomy (515), adenoma’s histologic type, location and complications during polypectomy. Results: 515 patients were submitted to colonoscopic polypectomy, 1,012 polyps were removed: 684 sessile (67.5%) and 238 pedunculated (32.4%), rectosigmoid segment was the most frequent location (68%). 973 polyps were analyzed: 593 (61%) were adenomatous polyps and the remainder were non-neoplasic, from neoplasic: 484 (81.6%) were tubular, 78 (13.3%) tubulovillous and 31 (5.2%) villous. The most frequent complication was bleeding in 0.2% of cases. Conclusions: Colonoscopic polypectomy is an adequate procedure for diagnostic and therapeutic in removal of colorectal polyps; is a safe and effective procedure that can decrease the polyp-cancer sequence in colorectal polyps.
