"Endoscopic" - Use of an endoscope.
"Retrograde" - Injection of dye into the bile ducts in a direction against the normal flow of bile down the ducts.
"Cholangiopancreatography" - Visualization of the bile ducts (cholangio) and pancreas (pancreato).
Endoscopic retrograde cholangiopancreatography (ERCP) is a technique that enables provider to examine the pancreatic and bile ducts using X-Ray.
ERCP is used to determine:
ERCP is done to diagnose and treat patients suffering from disorders of liver,bile ducts,pancreas & gallbladder.It is performed in an X-Ray Room
The patient is asked to lie on the left side and a sedative is generally given to patient.Then, a endoscope is inserted into esophagus till the common bile duct. Now, the patient is turned to lie flat and provider passes a plastic tube into the opening of common bile duct.
Then a dye is injected into the common bile duct.A Radiologists will take X-Rays images.If a gallstone is found, a very small incision is given at the opening of the bile duct. This causes widening of the opening. The blocked stone now is easily removed.
If the duct has become narrowed. Biopsies i.e small tissue samples can be taken for further examination.
This procedure takes around 20 to 45 minutes.
