Abstract
A case of left-sided gallbladder combined with both an accessory bile duct and an anomaly of the intrahepatic portal vein, was confirmed accidentally by laparoscopic cholecystectomy was reported. A 41-year-old woman with cholelithiasis was admitted to our hospital and laparoscopic cholecystectomy was performed. The gallbladder was located in the left side of the round ligament, (left-sided gallbladder). It was also complicated with right round ligament and an accessory hepatic bile duct. There are only 50 reports of left-side gallbladder without situs inversus totalis in Japan, but in 9 of these cases the gallbldder misplacement was combined with a portal vein anomaly as in our case. For these cases, some authors advocate another possible mechanism: A left-sided gallbladder might arise when the right round ligament remains and the gallbladder develops at the left of this ligament. This could be added to Gross' theory.
