Minimally invasive gallstone surgery time, which varies mainly according to the different sites where the stones occur, generally ranges from half an hour to an hour or even longer. As the most common benign disease of the hepatobiliary system, gallstones can occur in the gallbladder, liver, and common bile duct. Currently, gallbladder stones occur most commonly in the gallbladder, some common bile duct stones, and very rarely may be intrahepatic bile duct stones. Simple gallbladder stones are usually treated by laparoscopic cholecystectomy, which takes about half an hour to one hour. If the stone is in the common bile duct, a laparoscopic choledochotomy with T-tube drainage is required, and the operative time is relatively longer than the time for the gallbladder alone by half an hour or even longer. If it occurs in the liver, a lobectomy or segmental resection of the liver is required, and the operation will take even longer. The time for minimally invasive gallstone surgery varies mainly according to the location where the stones occur.
