Laparoscopic cholecystectomy and common bile duct exploration for cholecystocholedocholithiasis with a left-sided gallbladder: report of a case.

A 75-year old woman was admitted to our hospital with right upper quadrant pain, vomiting, and jaundice. Laboratory findings showed elevated total bilirubin, alkaline phosphatase, gamma-glutamyl transpeptidase, and C-reactive protein levels. Abdominal ultrasonography (US) and drip infusion cholangiographic computed tomography (DIC-CT) showed not only cholecystocholedocholithiasis, but a gallbladder located left of the round ligament and close to the lateral segments of the liver.
