[A case of obstructive jaundice due to the movement of pancreatic calculi].

A 44-year-old man with a history of chronic alcoholic pancreatitis and Crohn's disease presented with abdominal pain. Computed tomography revealed pancreatic calculi in the head of the pancreas and a dilated pancreatic duct. The patient was diagnosed with an acute exacerbation of chronic pancreatitis due to the impact of pancreatic calculi on the main pancreatic duct. During the clinical course, the movement of pancreatic calculi to the major papilla was confirmed, leading to obstructive jaundice. Endoscopic treatment with sphincterotomy of the pancreatic duct was successful. Herein, we report the case of an unusual clinical course involving obstructive jaundice caused by the movement of pancreatic calculi.
