A Rare Case of Extrahepatic Bile Duct Anomaly Associated with Multiple Stones

Abstract

Congenital anomaly of the extrahepatic biliary system is relatively common, especially vascular variations are much more frequent than anatomic variations. The normal anatomical structure is encountered in only 35 percent of individuals, many of these variations have little or no clinical improtance, but some cases induce symptoms and signs or may lead to incorrect diagnosis and inappropriate management. These are very important to correct diagnosis of biliary variations observed during ultrasonography, cholangiography and endoscopic retrograde cholangiopancreatography(ERCP) and to accurate management by surgeon or endoscopist since accidental section or ligation of aberrant structures can lead to serious complications. We experienced a very rare case of extrahepatic bile duct anomaly confirmed by ERCP. The right and left extrahepatic ducts were connected at the level of the pancreatic segment of the common bile duct and the cystic duct drains to the right extrahepatic duct. There were several stones in the distal portion of the left extrahepatic duct and gallbladder.
