Gastroduodenal Intussusception, Intermittent Biliary Obstruction and Biochemical Pancreatitis due to a Gastric Hyperplastic Polyp.

We present the case of a 76-year-old man with gastroduodenal intussusception secondary to a gastric hyperplastic polyp. Intussusception in the adult population occurs infrequently. Our patient presented with gastroduodenal intussusception, which is very uncommon and accounts for <10% of all types of intussusception.
