We report a case of chronic pancreatitis with pseudocyst rupture into the common bile duct (CBD).
A 60-year-old man was admitted to our hospital because of chronic pancreatitis complicated with a pancreatic cyst. Abdominal CT scan showed the homogeneous cystic lesion with a smooth wall located at the pancreatic head. Endoscopic retrograde pancreatography demonstrated a pancreatic cyst which communicated with the pancreatic duct and ruptured into the CBD. Thus, the diagnosis of chronic pancreatitis with pancreatic cyst was made. Because the cyst ruptured into the CBD, we could not exclude malignant neoplasm. Pylorus-preserving pancreatoduodenectomy with D2 lymphnode dissection was perfomed. Pathological diagnosis of the lesion was chronic pancreatitis with pseudocyst. It should be noted that various complications can be associated with chronic pancreatitis.
