Patients undergoing laparoscopic cholecystectomy usually need anesthesia for about an hour, with additional time for special cases. For patients undergoing open cholecystectomy, anesthesia takes about two hours. Cholecystectomy is the most common procedure performed in biliary surgery. In most cases the operation is standardized and the long-term results are satisfactory. It is suitable for all kinds of acute and chronic cholecystitis and symptomatic gallbladder stones. Laparoscopic cholecystectomy usually takes about one hour to complete, but when some patients have more serious conditions, abnormalities in the structure of the gallbladder, separation difficulties, or other complications during the operation, it is necessary to convert to open surgery, which takes about two hours. After surgery, patients should pay more attention to wound care, regular disinfection and dressing change, which is conducive to wound healing. In the early postoperative period, it is advisable to adopt a diet low in fat, low in cholesterol, and containing sufficient high-quality proteins, vitamins and micronutrients, and to go to the hospital regularly for review.
