- Abstract: BACKGROUND/AIMS: Colonoscopic polypectomy is an effective tool for the treatment of colonic polyps. With the recent widespread use of colonoscopic polypectomy, there is a growing concern about iatrogenic complications, such as bleeding and perforation. The aim of this study is to analyze the clinical presentation and management of complications during colonoscopic polypectomy. METHODS: We retrospectively reviewed the medical records of colonoscopic examinations performed at 5 hospitals of Hallym University Medical Center between June 2005 and June 2008. RESULTS: A total of 26,773 colonoscopies and 4,123 colonoscopic polypectomy were performed. The overall rate of complication was 1.04% (43/4,123). Perforation occurred in 0.19% (8/4,123) of cases, and bleeding occurred in 0.85% (35/4,123) of cases. Perforation occurred in 0.05% of snare polypectomies, 1.09% of endoscopic mucosal resections (EMR), and 7.14% of endoscopic submucosal dissections (ESD). Bleeding occurred in 0.8% of snare polypectomies, 1.09% of EMRs, and 3.57% of ESDs. The complication rate of ESDs was higher than in EMRs and snare polypectomies (P<0.001). Endoscopic clippings were performed in 25% of perforation and 66.7% of bleeding cases. Medical treatment was successful in 75% of perforation and 100% of bleeding cases. CONCLUSIONS: Colonoscopic polypectomy is a safe procedure for the treatment of colonic polyps, but rarely, serious complications occur. Compared to a snare polypectomy or an EMR, the complication of an ESD occurs more frequently. Endoscopic treatment and further conservative management seems to be appropriate in most cases with complication.
