Gallstones, also known as gallbladder stones. The cost of gallstone surgery varies depending on regional differences, hospital level, disease condition, and surgical method. In medical institutions above the provincial level, the most common surgical method for gallstones is minimally invasive laparoscopic surgery with faster recovery, and the cost of surgery at a level 1 medical institution is in the range of approximately $13,000-15,000. Open gallbladder surgery is also available, and the cost is relatively lower than minimally invasive surgery, at around 10,000-13,000 yuan.
