title: Factitial mesenteric avulsion.
abstract: Colon exteriorization procedures were done in two patients who also were, or became, psychotic. Each patient pulled on the exteriorized loop, causing severe bowel injury. In known or potential psychotics some other form of colonic injury management--other than exteriorization--should be utilized, or extreme caution should be taken to prevent inadvertent self-injury by the patient.
