ERCP (Endoscopic Retrograde Cholangiopancreatography) is a technique called endoscopic retrograde cholangiopancreatography, in which the duodenoscope is inserted into the descending duodenum through the mouth, and the bile and pancreatic ducts are accessed through the duodenal papilla for imaging and other diagnostic operations. The duodenal papilla is the opening of the bile and pancreatic ducts in the duodenum, which is also the outlet of bile and pancreatic juice. ERCP technology has developed from a purely diagnostic technology to a comprehensive technology mainly for treatment, including: cholangiopancreatography; duodenal papillary sphincter dissection and dilation; bile duct and pancreatic duct stone lithotomy and extraction; bile duct and pancreatic duct stricture dilation; nasobiliary duct and nasopancreatic duct drainage; bile duct stent and pancreatic duct stent placement and drainage, etc. The Department of Gastroenterology of our hospital has fully developed various ERCP techniques. The main indications of ERCP technology: 1, bile duct stones, tumors, inflammation, parasites; 2, recurrence of symptoms after cholecystectomy, bile duct surgery, unexplained obstructive jaundice; Oddi’s sphincter dysfunction; 3, recurrent pancreatitis, biliary pancreatitis, chronic pancreatitis, pancreatic tumors; 4, congenital malformation of bile and pancreas, bile-pancreatic duct confluence abnormalities; 5, bile Biliary fistula, pancreatic fistula and stenosis after biliary and pancreatic surgery and trauma; 6. Duodenal papilla and jugular abdominal tumor; ERCP minimally invasive technology advantages: 1. 2. Mature technology, high success rate and few complications. 3, short treatment time, low cost, fast recovery: after surgery, you can go down to the floor and resume eating the next day, and generally only need to be hospitalized for 3 to 5 days, the treatment cost and hospitalization time is 1/2 to 1/3 of traditional surgery. 4, wide range of indications, not subject to the restrictions of adhesions of the common bile duct after repeated surgery and old and weak, ERCP technology to reduce the treatment risk, more conducive to patient recovery. Our gastroenterology department relieves the pain of more than 300 patients with biliary and pancreatic diseases through ERCP technology every year. After continuous technical improvement, the success rate of ERCP technology operation is 96%, which reaches the advanced level in China, and we can skillfully perform various complicated and difficult ERCP technology operations, and at the same time, we have technical cooperation with famous ERCP centers and experts in China, such as Shanghai, to ensure our advanced in ERCP technology to better serve patients with hepatobiliary and pancreatic diseases.
