Colonoscopy‐associated perforation: a 7‐year survey of in‐hospital frequency, treatment and outcome in a German university hospital

Abstract

Death from perforation after colonoscopy is rare, occurring in 1/3500 examinations. The risk is increased in therapeutic colonoscopy and in the presence of previous gastrointestinal disease. Dilatation, SMR and APC appeared to confer a higher risk of perforation than polypectomy or diagnostic colonoscopy.
