Intussusception complicated by distal perforation of the colon

Abstract

Three cases of perforation of the colon distal to an ileocolic intussusception are presented. Two cases were associated with attempted hydrostatic reduction of the intussusception, while the other was discovered at operation. The mechanism of this complication is not clear. When performing a contrast enhanced examination of the colon and there is a risk of perforation: (a) dilute water-soluble contrast medium should be used; (b) special attention should be paid to the colon distal to the intussusception; and (c) should contrast material be observed in the peritoneal cavity, the enema reservoir should immediately be lowered to the floor to siphon off the liquid from the colon.
