Duodenal duplication cyst and recurrent pancreatitis in the setting of duodenal atresia

We report a case of recurrent pancreatitis caused by a duodenal duplication cyst with aberrant pancreatic ductal communication in a {Mathematical expression}-year-old female who had been previously treated for duodenal atresia. The evaluation of the pancreas included a computed tomography scan, endoscopic retrograde cholangiopancreatography, intraoperative ultrasound, and intraoperative cholangiogram. In the setting of duodenal atresia, this case underscores the complex embryology of pancreatic, duodenal, and biliary development. Any infant with recurrent pancreatitis should have a complete evaluation in order to identify a potentially correctable lesion. The surgical options remain defined by the anatomy and include resection, marsupialization, or internal drainage.
