Harms of Colonoscopy

Clinical Question:
What are the harms of colonoscopy?

Bottom Line:
Overall, the harms per 100,000 colonoscopies were 50 perforations, 260 bleeds, and 3 deaths. Among patients undergoing screening colonoscopy, the likelihood of a bleeding complication was 240/100,000 and the likelihood of a perforation was 30/100,000. (LOE = 1a)
