Two Suspected Cases of Intussusception due to Escherichia Coli O-157 Infection

Abstract

Hemorrhagic colitis due to Escherichia coli O-157 infection causes intestinal edema. In these cases, an abdominal ultrasonography shows findings similar to intussusception, and secondary intussusception may occur.
We report on two children who underwent laparoscopic examination because of possible intussusception. Case 1: A 15-year-old boy was subjected to laparoscopic examination due to failure of barium enema reduction for intussusception. Case 2: A 6-year-old girl was similarly examined because of recurrence of intussusception after two times of barium enema reduction.
In both cases, the cecum and ascending colon were edematous without intussusception; i.e. possible causes of intussusception. Postoperatively, E. coli O-157 were detected in stool sample. Therefore, medical treatments were performed in both patients.
In elder children with suspected intussusception, we should always be reminded of possible infection from E. coli O-157 colitis to avoid unnecessary surgery.
