Gallbladder stones are a common and frequent disease, although not a major problem, they do cause great physical and psychological problems to “stone sufferers”. The problems caused by stones include: interference with the concentration and storage of bile, affecting the digestive function, easy to eat after the fullness of discomfort, indigestion; stones block the gallbladder duct, inducing biliary colic or acute cholecystitis; stones fall into the bile duct, causing cholangitis or even pancreatitis; stones in the gallbladder long-term stimulation caused by chronic cholecystitis or even gallbladder cancer; even patients with no symptoms of stones, there will be a psychological burden. The treatment of gallbladder stones mainly includes drug lithotripsy, cholecystectomy and the controversial biliary stone extraction. In general, drug lithotripsy is limited and may be effective for sediment-like stones; laparoscopic cholecystectomy is currently recognized as the treatment of choice for gallbladder stones, with the advantage of removing stones while completely eliminating the soil in which they were produced. Cholecystectomy was not recognized by most doctors for a longer period of time and was labeled as catering to patients because of the very high recurrence rate. However, with the introduction of the concept of functional surgery, the advancement of minimally invasive surgical techniques and the application of new litholytic drugs, laparoscopic combined choledochoscopic cholecystectomy for stone extraction with preservation of gallbladder function has once again attracted the attention of clinicians. The main advantages of laparoscopic combined choledochoscopic cholecystotomy and stone extraction surgery are as follows: 1. While removing the stones with the help of choledochoscope, the gallbladder function is preserved, avoiding the problem of intolerance to greasy food that tends to occur in the early stage after cholecystectomy. 2. Since the gallbladder is preserved, the storage and excretion of bile and hepatic-intestinal circulation are not changed, avoiding the change of intestinal environment and the subsequent problems caused by it. 3. The surgery performed under laparoscopy is very traumatic and the adhesions in the abdominal cavity are light, which will not make the surgery more difficult even if another surgery is needed in the future. Of course, we cannot avoid the problem of recurrence of stones, and it is true that some patients may grow stones again. However, we can look at this procedure as an investment, exchanging the cost of one general anesthetic for the right to use the gallbladder for a period of time. Whether the investment will be profitable or a loss depends largely on how long the gallbladder is used, so how long is it worth it? It depends on the individual’s understanding. What we doctors can do is to delay the recurrence and prolong the use to the maximum extent possible. Specific practices include: 1. Strictly grasp the indications for surgery: the gallbladder wall is not thick, not more than 3 mm measured under ultrasound during fasting; good contractile function of the gallbladder; single large stones or multiple stones that are not very numerous. 2. Strictly exclude contraindications to surgery: mud-like stones; combined gallbladder adenomyosis or gallbladder polyps; combined bile duct stones. 3.Take ursodeoxycholic acid regularly after surgery. 4.Lifestyle regulation after surgery, avoid high cholesterol diet, eat three meals a day on time. 5. For patients with combined coronary heart disease and other medical diseases, cholecystectomy should be performed when indicated in order to avoid inducing the onset of medical diseases, and biliary stone retrieval is not recommended.
