Choledochoscopy is becoming more and more popular, both during and after surgery of the biliary tract, and the opening of the common bile duct basically requires the use of choledochoscopy. Choledochoscopy can remove stones as well as understand the overall condition of the bile duct. The cost of intraoperative choledochoscopy is usually around 400-1000 RMB, because the cost should be increased by taking into account the removal of stones from the common bile duct, which can reach 1000 RMB. After the surgery, according to the distribution of stones in the common bile duct, the choledochoscope can be applied several times, and the cost will definitely increase. If we simply do choledochoscopy, the general cost is 400 yuan, and disposable supplies are counted separately, and the cost may be reduced in the primary hospital, which is about 300 yuan. If you perform cholangioscopy to understand the overall situation of the biliary tract, whether there are tumor lesions and the patency of the biliary tract, the cost is only 500 yuan.
