Case report of a gastric bezoar causing anterograde gastroduodenal intussusception requiring surgical intervention in a 15‐year‐old female

Gastroduodenal bezoars are masses of indigestible material that accumulate within the stomach and may lead to obstruction. We present a young female who presented with abdominal pain, nausea, and vomiting, and was found to have a large gastric bezoar extending into the duodenum, resulting in gastroduodenal intussusception. Endoscopic removal was unsuccessful due to the size of the mass, which consisted predominantly of hair. The patient underwent surgical removal, with resolution of symptoms and uneventful recovery. This case highlights an uncommon cause of gastroduodenal intussusception and emphasizes the importance of recognizing bezoars as a potential lead point in patients with obstructive symptoms. Prompt diagnosis and intervention are essential, particularly when endoscopic management is not feasible.
