Duplicate pancreas meets gastric duplication cyst: A tale of two anomalies

INTRODUCTIONCongenital anomalies are a rare cause of pancreatitis in adults. Gastric duplications are the least common duplication of the gastrointestinal tract and are even more uncommon in the setting of a duplicate pancreas.PRESENTATION OF CASEThis manuscript contains a case report and review of the literature of an adult who presented with recurrent pancreatitis and was found to have a gastric duplication cyst that communicated with a duplicate pancreas. The study aim is to alert practitioners to the duplicate anomaly and recommend appropriate therapy.DISCUSSIONCombined gastric and pancreatic duplications usually occur in young females with nonspecific, recurrent abdominal pain. This combined duplication can result in pancreatitis when the gastric duplication is contiguous with the stomach. Heightened awareness of the condition, appropriate diagnostics with accurate interpretation and a minimalist approach to resection are warranted.CONCLUSIONRecurrent abdominal pain and pancreatitis in young adults devoid of risk factors should lead to consideration of congenital anomalies. Not all cysts near the pancreas and stomach are pseudocysts. ECRP and abdominal CT/MRI provide critical diagnostic information. This dual anomaly is best treated by simple excision of the gastric duplication and heterotopic pancreas.
