Introduction:
Postoperative small bowel obstruction due to intussusception is a rare entity but can lead to severe morbidity and even mortality. We present a case of this rare complication produced by an unusual cause.
Case report:
A 22year old male, who is a fruitarian, presented to the E.R on day 6 after laparotomy due to obstructing fetobezors that were removed via gastrotomy and enterotomy. In his readmission, he had severe, diffuse abdominal pain, distended abdomen and diffuse peritonitis. Abdominal computed tomography (CT) showed a large amount of fluid in the abdomen, distended small bowel loops, a small amount of free air around the stomach and a suspected ileo-ileal intussusception. The patient underwent emergent laparotomy which revealed an ileo-ileal intussusception with the sutured enterotomy site from the previous operation as the lead point. In addition, a minor dehiscence of the gastrotomy site was identified. A reduction of the intussusception was performed with resection of the enterotomy site and side to side anastomosis. The gastrotomy site was debrided and re-sutured. Recovery was uneventful.
Conclusion:
Postoperative intussusception, although rare, is potentially a dangerous complication, often not involving the site of the primary operation. To our knowledge this is the first report of an intussusception with a sutured enterotomy site as the lead point. Clinicians should be aware of this entity when assessing a patient with abdominal pain and distention after surgery with enterotomy or resection of bowel.
