The price of cholangiopancreatography is usually around 10,000~50,000 RMB, and there is a big difference in the exact cost, so it is recommended to consult the local hospital. Cholangiopancreatography, or ERCP for short, is an important means of diagnosing biliary and pancreatic diseases and treating bile duct stones and obstructive jaundice. Endoscopic retrograde cholangiopancreatography is an advanced non-invasive or minimally invasive method for diagnosis and treatment of biliary and pancreatic diseases. It can clearly show the bile ducts and pancreatic duct system inside and outside the liver, and can show the lesions and location of stones, tumors, etc. It has a unique value in diagnosing pancreatic and biliary diseases, and biopsy and other tests can be performed at the same time. The cost of normal imaging is about 10,000 RMB, and if stone removal or stent implantation is needed, the cost can be up to 50,000 RMB. ERCP diagnostic and therapeutic technology has the advantages of simplicity, rapidity, less pain and fewer complications, which replaces surgery to a certain extent, and is a minimally invasive interventional treatment, which is the main direction of the development of gastrointestinal endoscopy at present.
