Abstract
A previously healthy 23-year-old man admitted for abdominal pain, frequent diarrhea, and vomiting, was found in abdominal computed tomography (CT) to have an ileo-colonic intussusception without a mass lesion at the leading point. Aggravated abdominal pain necessitated emergency operation that day. After manually fixing the intussusception, we performed ileocecal resection because the cecum was very edematous, solid, and appeared malignant. Histopathological cecal features included edematous focal wall thickening and nonspecific colitis. The postoperative diagnosis of Shigella flexneri and Campylobacter jejuni was made by preoperative and postoperative stool cultures. The cause of enterocolitis-induced intussusception mainly concerned leading point formation by acute inflammatory change, abnormal peristalsis, and anatomical factors. This case demonstrated intussusception as a complication of enterocolitis, underscoring that enterocolitis is in fact a potential cause of intussusceptions, and some reports reveal the feasibility of conservative therapy for enterocolitis-induced intussusception without surgical intervention.
