The surgical methods for the treatment of cholecystitis and gallstones (including gallbladder stones, common bile duct stones and intrahepatic common bile duct stones) are: 1) cholecystectomy. 2) cholecystectomy plus common bile duct dissection and stone extraction and exploration. 3) cholecystectomy and gallbladder sclerosis. 4) hepatic dissection and stone extraction or partial hepatectomy. Among them, cholecystectomy has become the classic treatment for organic lesions of the gallbladder. By removing the diseased gallbladder, cholecystectomy not only takes away the material basis and place for stone growth, thus achieving the purpose of cure. Nowadays, with the development of science and technology and the improvement of medical instruments, laparoscopic removal of gallbladder without opening the abdomen is more and more widely used due to the small damage and fast recovery, which is welcomed by the majority of patients. With the development of small-injury techniques to reduce the high cost of laparoscopic equipment and surgery, one can choose to perform small incision cholecystectomy.
