There are several types of minimally invasive surgery for common bile duct stones. 1. endoscopic stone extraction, called ERCP, is like doing a gastroscope, going in through the mouth, to the stomach, duodenum, and then to the bile duct to pull out the stone, which is relatively less invasive and less expensive, between 10,000 and 20,000 yuan. Because the valve between the duodenum and the bile duct needs to be cut, it will cause the intestinal fluid to reflux into the bile duct, and the risk will be increased in the long term.2. Laparoscopic choledochotomy for stone extraction plus T-tube drainage, the cost of this procedure is about 30,000 yuan. Depending on the post-operative recovery, the price may fluctuate somewhat. 3, bile-intestinal anastomosis, the utilization rate of this surgical method is relatively low, because the side effects are relatively large, the cost is relatively high, the reconstruction of the biliary tract is needed, this kind of use is relatively small, its cost is about 70,000-80,000 yuan.
