Gastroduodenal intussusception secondary to a gastric lipoma.

Gastroduodenal intussusception caused by a gastric lipoma is an uncommon condition, and only a few cases have been reported in the medical literature. A case of a 72-year-old man who complained of weight loss and intermittent episodes of nausea and vomiting is presented. Diagnostic workup demonstrated a mass in the second portion of the duodenum. The patient underwent a diagnostic laparoscopy followed by an exploratory laparotomy that confirmed the gastroduodenal intussusception by a gastric lipoma. In addition, the anatomical and clinical presentation, diagnosis and management of this entity are discussed.
