ERCP is the initials of retrograde endoscopic cholangiopancreatography, which is an endoscopic imaging technique to retrograde 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.
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 indications
It is generally considered that all suspected pancreaticobiliary diseases are indications, mainly including.
1, suspected of 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 in 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.
Contraindications to ERCP
1. Upper gastrointestinal stenosis or obstruction, and it is estimated that it is impossible to reach the descending duodenum.
2. Contraindications to other endoscopic examinations 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.
