Preduodenal Portal Vein and Left Sided Gallbladder in Hepatolithiasis Patient: A case report

ABSTRACT

A preduodenal portal vein is a rare anomaly. A left-sided gallbladder is also a rare anatomical variant that may be occasionally combined with a preduodenal portal vein. We report here a patient with multiple biliary stones whose preduodenal portal vein was discovered at operation. The anomaly was a preduodenal portal vein associated with a left-sided gallbladder, which is very rare. This is the first case reported in Korea. An abnormal location of the round ligament to the right side can make the gallbladder appear to be a left-sided gallbladder. Our case belongs to this category. This patient had multiple biliary stones in the intrahepatic duct, the common bile duct, and the gallbladder. We treated him with a cholecystec tomy, choledochotomy, and choledochoscopic stone extraction using a basket, and electrohydraulic lithotripter. All procedures were done using a laparoscopic method. The patient was treated well with no complication.
