Cholecystectomy is the fundamental treatment for acute cholecystitis. Indications for surgery: ① gangrene and perforation of the gallbladder with diffuse peritonitis; ② repeated acute attacks of acute cholecystitis with a clear diagnosis; ③ active medical treatment, but the condition continues to develop and deteriorate; ④ no contraindications to surgery and can tolerate surgery. In chronic cholecystitis with gallstones; once the diagnosis is established, cholecystectomy is a reasonable and fundamental treatment. If the patient has serious diseases such as heart, liver, lung or other systemic conditions that cannot tolerate surgery, medical treatment can be given.
