Coexistant gastric duplication and accessory pancreas: clinical manifestations, embryogenesis, and treatment

Abstract

Combined gastric and pancreatic duplications are uncommon. Although patients usually present with symptoms of intestinal obstruction, gastrointestinal (GI) bleeding may occur if the duplication ulcerates and erodes into a neighboring hollow viscus. An upper GI series and barium enema are helpful in making a diagnosis. Combined duplications probably are produced during embryologic development by traction along a neuroenteric band between the stomach and pancreas. Simple surgical excision is the treatment of choice.
