A Rare Case of Anterograde Gastroduodenal Intussusception Caused by Migrated Percutaneous Endoscopic Gastrostomy Feeding Tube

Gastroduodenal intussusception is a critical condition in which stomach protrudes into the duodenum. It is a very rare condition in adults. Most common causes include intra luminal lesions in the stomach including benign or malignant tumors of the stomach. Most common tumors included are gastrointestinal stromal tumors (GISTs), gastric carcinoma, gastric lipoma, gastric leiomyoma, and gastric schwannoma. It is extremely rare to be caused by migration of percutaneous feeding tube. A 50-year-old woman with a past medical history (PMH) of dysphagia status post percutaneous endoscopic gastrostomy (PEG) tube, history of spastic quadriplegia, presented with acute nausea, vomiting and abdominal distention, and was found to have gastroduodenal intussusception in computed tomography (CT) scan. Condition resolved after retracting PEG tube. Endoscopy did not reveal any intra luminal lesions. External fixation using Avanos Saf-T-Pexy T-fasteners was performed to prevent recurrence of this condition. Most common of causes of gastroduodenal intussusception are GIST tumors of stomach. CT abdomen is the most accurate test and upper endoscopy is needed to rule out any intra luminal causes. Treatment of choice is either endoscopic or surgical resection. External fixation is essential to prevent recurrence.
