Abstract:
Colonoscopy is a relatively invasive modality for the diagnosis and treatment of colorectal disease and for the prevention or early detection of colorectal neoplasia. Millions of colonoscopies are performed each year in the United States by endoscopists with varying levels of skill in colons that present varying levels of challenge. Although better scope technology has made colonoscopy gentler and more accurate, the sheer number of examinations performed means that complications inevitably occur. This article considers the most common complications of colonoscopy, and advises how to minimize their incidence and how to treat them if they do occur.
