The cost of ERCP surgery is calculated according to the grade and complexity of the various procedures and the number of instruments used, so it varies, and may range from 1 to 50,000 yuan. If it is just a small stone, there is no need to lithotripsy, no other way, the column balloon is dilated and then a guide wire or knife is inserted to make a small incision, and the stone is cleared with a lithotripsy mesh basket or balloon, and this method can be done for about 10,000 yuan. However, if the stone of the common bile duct is very large, because the papilla cannot be expanded too large, too large may break off, cracked, to make an incision, the limit of expansion for the stone if it reaches more than 1.5cm, may have to be lithotripsy, lithotripsy to use the lithotripsy mesh basket, some people have to use the laser to fight, laser fiber is also more expensive. Another situation is that after the stone is crushed, the stone may be removed after one mesh basket is crushed, the mesh basket is deformed and cannot be used, and a second mesh basket has to be used, so the cost of this procedure will become higher. For tumors such as papillary cancer, duodenal cancer and bile duct cancer, stents are put in. If it is an ordinary plastic stent, one is only 800 yuan, even 600 yuan is available, and there are also imported and domestic stents around 1000 yuan. However, if you want to use metal stents, domestic stents may cost 6,000 or 8,000 RMB, and imported ones may cost 11,000 or 12,000 RMB. There are also more expensive metal stents with overlay, which can be recycled, costing about 20,000 yuan, because the difference in materials leads to the difference in cost. But in general, the simple contrast, simple must use is the guide wire, contrast catheter, and ordinary equipment, the approximate cost is about 10,000 yuan.
