Acute suppurative cholecystitis may further develop into gangrenous cholecystitis or perforation, and emergency cholecystectomy is required; for chronic cholecystitis without stones , those with mild symptoms should be treated with caution, especially young female patients who can undergo non-surgical treatment first; for patients with intrahepatic bile duct stones who have hilar bile duct stenosis, in order to remove all the stones and relieve the stenosis, high hepatic bile duct surgery is often required. Lithotomy, plastic surgery, and bile enteral drainage are necessary; the simplest and most effective method for AOSC is common bile duct incision, decompression, and T-tube drainage.
