Abstract
PBM is a congenital anomaly in which the pancreatic duct and bile duct join anatomically outside the duodenal wall, usually forming a markedly long common channel. EUS can observe not only the pancreatic and bile ducts but also the muscularis propria of the duodenum and pancreatic parenchyma. In PBM patients, EUS can detect the confluence of the pancreatic duct and bile duct outside the muscularis propria of the duodenal wall regardless of the length of the common channel. In addition, in PBM, bile duct cancer and/or gallbladder cancer is frequently observed and more predisposed to forming biliary tract stones than individuals without the disease. EUS can evaluate not only the diagnosis of PBM but also further examine the bile duct and gallbladder in the same session. Experienced specialists must perform or assist EUS as its diagnostic accuracy is guaranteed by operator skills.
