Acute duodenal obstruction secondary to intussusception caused by the duodenal diverticulum: A case report

Abstract

Background: The duodenal intussusception is rarely reported and usually occurs secondary to organic diseases of the duodenum such as polyps, tumors and duplication cysts. Herein we report a case of duodenal intussusception caused by duodenal diverticulum. Case presentation: A 21-year old male patient presented with abdominal pain and vomiting for one day. A contrast enhanced computed tomography of the abdomen revealed duodenal intussusception. On emergency laparotomy, the intussusception had reduced spontaneously while an invaginated diverticulum was seen at the junction of the descending and horizontal segments of the duodenum. The diverticulum was resected and the patient had uneventful recovery. Conclusion: Duodenal intussusception is a rare complication of duodenal diverticulum. Being aware of this complication of diverticulum can help in timely diagnosis and treatment.
