An Unusual Presentation of Small Bowel Intussusception

Abstract

Adult small bowel intussusception is a very rare entity that accounts for 5% of all cases of intussusception and 1%–5% of intestinal obstructions. It is more common in children but can occur in adults. It is an important etiology to consider when a patient presents with recurrent abdominal pain. The diagnosis can be challenging as symptoms are nonspecific and include abdominal pain, nausea and vomiting. This paper presents a rare case of duodenal intussusception, followed by a review of the literature discussing the diagnosis and treatment of adult intussusception.
