Recurrent Acute-on-Chronic Pancreatitis in a Chronic Alcoholic With Pancreatic Divisum: A Complex Case.

Pancreatic divisum, a rare developmental anomaly of the pancreas, is infrequently observed in young individuals and is a recognized cause of recurrent acute pancreatitis, ultimately progressing to chronic pancreatitis. Chronic alcoholism is a prevalent and significant etiological factor contributing to both recurrent acute pancreatitis and chronic pancreatitis. This case report details the presentation of a 28-year-old patient with a history of chronic alcoholism, exhibiting recurrent acute pancreatitis evolving into chronic pancreatitis. Diagnostic evaluation revealed the presence of pancreatic divisum with associated pancreatic intraductal calculi, a common trigger for pancreatitis. The patient underwent successful management through endoscopic retrograde cholangiopancreatography, pancreatic lithotripsy, and pigtail pancreatic stent placement. This case highlights the complex interplay between chronic alcoholism leading to recurrent acute pancreatitis and pancreatic divisum, a rare congenital anomaly, which is found later in this case, complicating the disease.
