A 76-year-old patient presented with pancreatic duct dilatation on magnetic resonance imaging (MRI). The patient had no symptoms and no previous history of hepatobiliary or pancreatic disease. Endosonography showed pancreatic duct dilatation (12mm) in the pancreatic body and tail. The pancreatic duct in the pancreatic head was only moderately dilated (5mm). Endoscopic retrograde cholangiopancreatography (ERCP) showed a normal major papilla and normal biliary system. Pancreatography revealed a blind-ending main pancreatic duct of only 35mm in length. The minor papilla was found in the typical position, 2 cm above themajor papilla. Pancreatography confirmed the dilated main pancreatic duct in the pancreatic body and tail, with a narrow Santorini duct (▶Fig. 1 a), so a plastic drain was inserted. Chronic pancreatitis because of pancreas divisum was assumed to be the reason for the duct dilatation. E-Videos
