Recurrent acute pancreatitis caused by combined gastric and pancreatic duplications: value of preoperative CT and MRCP and conservative surgery.

We present a series of patients with recurrent acute pancreatitis caused by a duplicated pancreatic head connected to a gastric duplication and successfully treated by conservative surgery. This retrospective study included consecutive adult patients referred to our institution for recurrent acute pancreatitis. All patients underwent a preoperative non-invasive imaging examination including contrast-enhanced computed tomography and magnetic resonance cholangiopancreatography (MRCP). The final diagnosis of this developmental anomaly was based on surgical and pathological examinations. The four patients in this study had the same typical imaging pattern including a duplicated duct. There was no recurrent acute pancreatitis after surgical treatment, which involved atypical resection of the duplicated pancreatic head and segmental gastric resection, without a Whipple procedure. The discovery of an accessory pancreatic head with a duct terminating in a cyst identified on MRCP in a patient with recurrent acute pancreatitis could suggest this rare and surgically treatable cause of acute pancreatitis.
