Choledocholithiasis is characterized by high incidence, inaccessibility of stone removal, and difficulty in lithotripsy, and there is no specific treatment at home or abroad, thus causing cholestasis, cirrhosis and even liver cancer in many patients with intrahepatic choledocholithiasis due to lack of effective treatment. Surgical treatment of gallbladder stone disease includes: a. Traditional open cholecystectomy: This procedure was first performed by German doctor Lovengen-buch in 1882, and has a history of more than 100 years. surgical treatment under suitable conditions. However, the hepatobiliary surgery in large general hospitals is only used as a supplement to laparoscopic cholecystectomy. The disadvantages are large incision (10cm±), large tissue trauma, postoperative bed rest, long fasting time, slow recovery, and greater pain to patients. Small incision cholecystectomy: Based on traditional cholecystectomy, it is improved and mainly uses small incisions (4cm±), modified surgical instruments and surgical field illumination, and is suitable for the surgical treatment of various acute and chronic calculous cholecystitis. The addition of a choledochoscope can be used for biliary exploration of secondary common bile duct stones (stones from the gallbladder). The disadvantage is that although it is less invasive, the operation is also poorly exposed and cannot fully understand the situation in the abdominal cavity, especially in obese patients, because of poor exposure and stronger traction, the surgeon’s surgical operation is laborious. Third, laparoscopic cholecystectomy: introduced into China in 1991, causing the surgical community to attach great importance to the rapid development of domestic, China has received this operation has reached nearly 400,000 patients. Currently, about 80% – 99% of cholecystectomies are performed laparoscopically in hospitals with conditions, which have replaced open cholecystectomies. It is characterized by small incision (minimally invasive), safety, low pain, fast recovery, clear exposure of the surgical field, short operation time, and a comprehensive understanding of the intra-abdominal cavity during the operation, with many patients receiving surgery in the morning, getting out of bed in the evening, eating the next day, and being discharged on the fourth day after surgery. In the past 7 years, we have performed cholecystectomy for nearly 5,000 patients using laparoscopic operating system, and the majority of patients have responded well.
