Cholangiography how it is performed

Endoscopic retrograde cholangiopancreatography or ERCP is a specialized technique used to study the ducts of the gallbladder, pancreas and liver. The ducts are drainage ducts; those of the liver are called hepatic or bile ducts.

You will need to fast for at least six hours (preferably overnight) before the study to be sure that your stomach is empty, which is necessary for a better examination. Your physician will give you precise instructions for the preparation. You should mention to your physician all medications you usually take and any allergies you have to medications or intravenous contrast materials (dyes). Although an allergy does not prevent you from having an ERCP, it is important to discuss it with your physician before the test, as you may need specific allergy medications prior to the test. Tell your doctor what medications you are taking, especially aspirin products, arthritis medications, anticoagulants (blood thinners such as warfarin or heparin), clopidrogel, or insulin. Also, be sure to tell your doctor if you have any heart or lung conditions or other major illnesses that may override or influence the decision to perform the endoscopy.

ERCP is a well-tolerated procedure when performed by physicians specially trained and experienced in the technique. While complications requiring subsequent hospitalization may occur, they are rare. Complications may include pancreatitis (inflammation of the pancreas), infection, perforation and intestinal bleeding. Some patients may have an adverse reaction to the sedative used.

Cholangiorresonance. It consists of the injection of a contrast through the vein, which is eliminated by the liver and bile. Subsequently, an MRI is performed to observe the elimination of the contrast and to see how the biliary tract is filled. Endoscopic retrograde cholangiography (ERCP).

Percutaneous transhepatic cholangiography pdf

Magnetic resonance cholangiopancreatography, or MRCP, uses a powerful magnetic field, radio waves and a computer to evaluate the liver, gallbladder, bile ducts, pancreas and pancreatic duct for the presence of disease. It is noninvasive and does not use ionizing radiation.

Talk to your doctor about any health problems, recent surgeries or allergies, and whether there is a possibility that you are pregnant.

What is the main diagnostic indication for ERCP?

The main indication is the extraction of stones from the common bile duct (choledocholithiasis). But there are many other indications among which stand out: Obstructive jaundice, stenosis ( narrowing ) of the biliary tract, spontaneous or post-surgical biliary fistulas, tumors, parasites….

Intravenous cholangiography

Endoscopic retrograde cholangiopancreatography (ERCP) is a procedure that combines gastrointestinal endoscopy of the upper digestive tract and x-rays to treat bile and pancreatic duct problems.

Physicians use this procedure to treat bile duct and pancreatic duct problems, and also to diagnose bile duct and pancreatic duct problems if they expect to treat the problems during the procedure. For diagnosis only, doctors may use noninvasive tests, which do not physically enter the body, instead of ERCP. Noninvasive tests, such as magnetic resonance cholangiopancreatography, a type of magnetic resonance imaging, are safer and can also diagnose many bile duct and pancreatic problems.

You should tell your doctor if you are pregnant or might be pregnant. If you are pregnant and need an endoscopic retrograde cholangiopancreatography to treat a problem, the doctor performing the procedure may make changes to protect the fetus from the X-rays. Research has found that this procedure is generally safe during pregnancy.1
