ERCP – Glossary ERCP is the acronym for Endoscopic Retrograde Cholangio-Pancreatography (ERCP), which is an endoscopic technique for retrograde visualization of the pancreaticobiliary duct by injecting a contrast agent through the duodenal papilla and is currently recognized as the gold standard for the diagnosis of pancreaticobiliary duct disease. ERCP is the gold standard for the diagnosis of pancreaticobiliary diseases. ERCP – Introduction On the basis of ERCP, interventions such as duodenal papillary sphincterotomy (EST), endoscopic nasal bile drainage (ENBD) and endoscopic internal bile drainage (ERBD) can be performed, which are popular among patients because they do not require incision, are less invasive and have a much shorter hospital stay. ERCP – ERCP indications It is generally considered that all suspected pancreaticobiliary diseases are indications, mainly including: 1, suspected bile duct stones, tumors, inflammation, parasites or obstructive jaundice with unknown causes. 2. Recurrence of symptoms after cholecystectomy or bile duct surgery. 3, clinical suspicion of pancreatic tumor, chronic pancreatitis or recurrent pancreatitis in remission. 4.Suspected inflammation or tumor of the duodenal papilla or jugular abdomen, and biliary pancreatitis to remove the cause. 5.Suspected congenital malformation such as common bile duct cyst and pancreaticobiliary duct confluence abnormalities. 6.Understood epigastric pain and suspected pancreaticobiliary tract disease. 7.Biliary and pancreatic disorders requiring collection of bile and pancreatic fluid or Oddi sphincter manometry. 8. Those who need endoscopic treatment for pancreaticobiliary disorders. 9.Pancreatic duct rupture is suspected after pancreatic trauma. 10.Suspected bile duct surgery with accidental injury. 11.Suspected congenital lesions of the pancreas. 12.Some liver disorders. ERCP – Contraindications to ERCP 1. Upper gastrointestinal stricture or obstruction, and it is estimated that it is impossible to reach the descending duodenum. 2, Those with other contraindications to endoscopy such as cardiopulmonary insufficiency. 3.Non-stone embedded acute pancreatitis or acute attack of chronic pancreatitis. 4.Those who have bile duct stricture or obstruction and do not have bile duct drainage technique. 5.For those who are allergic to iodine, non-ionic contrast agents can be used instead, and emergency preparations should be made before the procedure.
