There are many conditions for biliary lithotripsy, and the clinically recommended indicators for biliary lithotripsy include stone size <2 cm, gallbladder wall thickness <3 mm, gallbladder ejection fraction >30%, and no gallbladder atrophy. The necessary conditions are usually not only two, but also the following aspects: 1, with preservation value: normal gallbladder morphology and function, ultrasound examination shows clear gallbladder contour, normal size and position, moderate gallbladder wall thickness, smooth mucosa; normal gallbladder contraction function, with contraction and efficient bile reserve function, contraction up to 1/3 or more; 2, no relevant medical history: such as no history of upper abdominal surgery and liver cirrhosis history. In addition, the history of acute inflammation such as perforation is not feasible for biliary stone extraction because adhesions caused by upper abdominal surgery can hinder laparoscopic operation; 3. Not in the attack period: asymptomatic gallbladder stones, not in the inflammation period, and the number of stones should not be too many, preferably single, moderate in size, and not combined with common bile duct stones; 4. Strong willingness to preserve gallbladder: because of the possibility of recurrence after biliary stone preservation, the patient needs to have a strong willingness to The patient must have a strong will to preserve gallbladder and be willing to bear the corresponding consequences. Clinically, biliary stone extraction is also used for some special gallbladder stone patients, such as elderly high-risk patients with complications, children with normal gallbladder contraction function, or emergency patients with physical weakness, severe cholecystitis, organ failure, etc. According to the different degrees of trauma of biliary lithotripsy, biliary lithotripsy can be divided into incisional suture method, puncture to establish tunnel method, and biliary lithotripsy via physiological channel retrograde method, which is further divided into small incisional biliary lithotripsy, laparoscopic biliary lithotripsy, and endoscopic biliary lithotripsy via natural lumen. After choledocholithotomy, we should pay attention to limiting fat intake, eating dietary fiber foods in moderation, such as celery and bananas, to promote gastrointestinal peristalsis, and also combine with cholestatic drugs for recovery and regular review to ensure the treatment effect.
