LEFT-SIDED GALLBLADDER WITH ANOMALIES OF THE INTRAHEPATIC PORTAL-VEINAND ANOMALOUS JUNCTION OF THE PANCREATICOBILIARY DUCTAL SYSTEM - A CASE-REPORT

A 66-year-old man was admitted for an early cancer in the gastric corp us. At laparotomy, the gallbladder was located on the left side of the round ligament and attached to the lateral segment of the liver. This finding was compatible with a left-sided gallbladder. Postoperative u ltrasonograms and portograms demonstrated anomalies of the intrahepati c portal vein as follows; The Left umbilical portion and the posterior point of the portal branch were lacking. The posterior point was seen as an umbilical portion. An endoscopic retrograde cholangiopancreatic ogram showed the cystic duct entering into the right side of the commo nbile duct confluent to the accessory pancreatic duct. A Left-sided ga llbladder unassociated with visceral inversion is a rare congenital an omaly. Forty-one cases have been reported in Japan, five with anomalie s of the intrahepatic portal vein and two with anomalous junction of t he pancreaticobiliary ductal system. To our knowledge, our patient is the only case of the left-sided gallbladder which both congenital anom alies.
