Anterograde Gastroduodenal Intussusception: A Rare but Lethal Complication of Percutaneous Endoscopic Gastrostomy Tube Placement.

Percutaneous endoscopic gastrostomy (PEG) tube placement is one of the methods of providing enteral nutrition support and is often used in critically ill patients. There are several complications of PEG tube placement, including intussusception. Jejunojejunal and retrograde jejunoduodenogastric intussusception are well-documented complications of PEG tube placement. Here we describe the case of a 25-year-old female who was diagnosed with anterograde gastroduodenal intussusception with the PEG tube acting as a lead point. Our case is unique as, to the best of our knowledge, there are no documented cases of PEG tube-related anterograde gastroduodenal intussusception. The reported patient was found to have extensive gastric pneumatosis and portal venous gas concerning for acute ischemia. Such cases warrant immediate surgical intervention. However, in our case, the patient's family opted for comfort care measures.
