Ansa Pancreatica, an Uncommon Cause of Acute, Recurrent Pancreatitis

Case Rep Gastroenterol. 2021 Jul 1;15(2):587-593. doi: 10.1159/000516686. eCollection 2021 May-Aug.

Abstract

The pancreatic duct is vulnerable to developmental anomalies which may produce variations in its course and/or its configuration. Ansa pancreatica is the least common anatomic variant. It is characterized by the formation of an "S-shaped loop" from the main pancreatic duct to the minor papilla. Ansa pancreatica has been implicated as a cause of recurrent acute pancreatitis. We review existing literature on pancreatitis secondary to the ansa deformity and present a case of recurrent acute pancreatitis in a patient who was ultimately found to have the ansa deformity on endoscopic ultrasound.
