Duodenal duplication with accessory papilla causing recurrent pancreatitis in a child: a case report

We discuss a 16-year-old male patient who presented with three episodes of recurrent pancreatitis within the last 6 months. Preoperative imaging studies suggested a choledochal cyst within the second portion of the duodenum. Patient was taken to surgery and the lesion was removed. Pathology examination of the cyst revealed a duodenal duplication. The accessory pancreatic papilla entering the closed duplication cyst was the main cause of the pancreatitis in this child.
