Colonoscopy Perforation Rates Low and Decreasing

Bowel perforation, or a hole in the colon, is one of the complications of colonoscopy.  Different reported rates of perforation have been confusing. A pooled analysis of published studies of perforation rates was reported during a Digestive Disease Week session on May 31.  Including 17 different studies covering more than a quarter million colonoscopies, the perforation rate for therapeutic colonoscopy was 1 in 1,500 exams.  In purely screening or diagnostic tests, perforations occured in only 1 in 6,000 tests.  Perforation risk is about three times higher when polyps are removed during the colonoscopy. Analysis showed a trend toward decreasing rates of perforations over time.
