ERCP
EERCP (short for endoscopic retrograde cholangiopancreatography) is a procedure used to diagnose diseases of the gallbladder, biliary system, pancreas, and liver. The test looks "upstream" where digestive fluid comes from the liver, gallbladder, and pancreas to where it enters the intestines. In addition, ERCP can be used to treat problems in these parts of the digestive system.
Your healthcare provider guides the scope through your mouth and throat, then down the esophagus, stomach, and the first part of the small intestine (duodenum). Your healthcare provider can view the inside of these organs and check for problems. Next, he or she will pass a tube through the scope and inject a dye.
Why might I need ERCP?
You may need ERCP to find the cause of unexplained abdominal pain or yellowing of the skin and eyes (jaundice). It may be used to get more information if you have pancreatitis or cancer of the liver, pancreas, or bile ducts.
Other things that may be found with ERCP include:- Blockages or stones in the bile ducts
- Fluid leakage from the bile or pancreatic ducts
- Blockages or narrowing of the pancreatic ducts
- Tumors
- Infection in the bile ducts
During an ERCP, a gastroenterologist (doctor who specializes in treating diseases of the gastrointestinal system), uses a special endoscope (a long, flexible tube with a light and camera at the end) to examine the inside of the digestive system. The doctor identifies the place where the bile duct comes into the intestine and then feeds a tiny catheter (a plastic tube) into the duct and squirts in a contrast agent while X-rays are taken. The contrast agent allows the doctors to see the bile ducts, the gallbladder, and the pancreatic duct on the X-rays.
Once the source of the problem is identified, the doctor may then treat it by performing one of the following procedures. Sphincterotomy. This involves making a small incision (cut) in the opening of the pancreatic duct or the bile duct, which can help small gallstones, bile, and pancreatic juice to drain appropriately. Stent placement. A stent is a drainage tube that is placed in the bile duct or the pancreatic duct to hold the duct open and allow it to drain. Gallstone(s) removal. ERCP can remove gallstones from the bile duct, but not from the gallbladder itself.
