A 55-yr-old female was hospitalized with epigastric pain. Conventional ultrasonography revealed marked dilation of the common bile duct (CBD). Endoscopic retrograde cholangiopancreatography showed fusiform dilation of the CBD. The common channel of the pancreatic duct and choledochus was 20 mm long. A diagnosis of congenital choledochal dilation accompanied by anomalous arrangement of the pancreaticobiliary ductal system (AAPBDS) was made. Intraductal ultrasonography (IDUS) was performed. IDUS demonstrated the union of the pancreatic duct and choledochus within the pancreatic parenchyma. This meant that the union existed outside the duodenal wall, confirming the diagnosis of AAPBDS. Although endoscopic retrograde cholangiopancreatography alone could show the maljunction in this case, simultaneous IDUS will be useful in making an accurate diagnosis of AAPBDS.
一名55岁女性因上腹部疼痛入院。传统超声检查显示胆总管（CBD）明显扩张。内镜逆行胰胆管造影显示CBD呈梭形扩张。胰管与胆总管的共同通道长20mm。诊断为先天性胆总管扩张伴胰胆管系统异常排列（AAPBDS）。进行了导管内超声检查（IDUS）。IDUS显示胰管与胆总管在胰腺实质内汇合。这意味着汇合处存在于十二指肠壁外，从而确诊为AAPBDS。虽然仅内镜逆行胰胆管造影在该病例中可显示汇合异常，但同时进行IDUS将有助于准确诊断AAPBDS。
