After 3 Years of Starvation: Duodenum Swallowed Remaining Stomach

A 42-year-old morbidly obese patient (BMI 44.1 kg/m²) was admitted to our emergency room with upper abdominal pain, nausea, and cholestasis. Nine years ago, a vertical banded gastroplasty had been performed (former BMI 53.5 kg/m²) with a subsequent weight loss to BMI 33.0 kg/m². After regaining weight up to a BMI of 47.6 kg/m², 5 years ago a conversion to a gastric bypass was realized. A computed tomography of the abdomen showed an invagination of the remaining stomach into the duodenum causing obstruction of the orifice of common bile duct. The patient underwent an open desinvagination of the intussusception and resection of the remaining stomach. Gastroduodenal intussusception is rare and mostly secondary to gastric lipoma. To prevent this rare but serious complication, the remaining stomach could be fixed at the crura of the diaphragm, tagged to the anterior abdominal wall by temporary gastrostomy tube, or resected.
