Perforation of the colon and rectum--a newly recognized complication of CT colonography.

CT colonography (CTC) and conventional colonoscopy may have similar efficacy for detection of polyps >6 mm. Perforation of the colon and rectum is a relatively rare, but potentially morbid complication of CTC, especially in symptomatic patients. Older age and underlying concomitant colon pathology increase the risk of perforation. This review describes the incidence, clinical features, and management of colon perforations at CTC, a study that was considered risk-free until recently.
