Adverse events related to colonic endoscopic mucosal resection and polypectomy

Abstract

Colonoscopy is a commonly performed procedure. The rate of adverse events is 2.8 per 1000 screening colonoscopies. These adverse events include cardiovascular and pulmonary events, abdominal pain, hemorrhage, perforation, postpolypectomy syndrome, infection, and death. Serious adverse events, such as hemorrhage and perforation, occur most frequently when colonoscopy is performed with polypectomy. This article highlights the prevention and management of adverse events associated with polypectomy and endoscopic mucosal resection of colonic lesions.
