What is cholangiography?

Cholangiography is a medical procedure performed for visualization of a billiard tree or bile ducts. A biliary tree is a structure that bile, which is produced in the liver, passes before it goes to the intestines to spend the fats taken during the meal. This test usually includes the use of a special dye injected in the patient's bile ducts, followed by a number of X -rays. It is often performed to explore the area for blocking and narrowing, which can lead to cholangitis or bile duct inflammation. Symptoms of cholangitis are fever, abdominal pain, yellowed skin and liver enlargement.

There are several types of cholangiography. These include percutaneous transhepatic cholangiography (PTC), endoscopic retrograde cholangiopancreatography (ERCP) and postoperative cholangiography. They usually differ in the process of how the dye is introduced into a billiard tree.

For example, in the PTC, a long needle is injected into the abdomen to place the dye in a billion. In ERCP there is an endoscope that is flexibleThe tube with a camera attached at the end, usually inserted into the patient's mouth until it reaches the first part of the small intestines. In this way, a thin tube or catheter follows the bile ducts, followed by a dye in the area. Patients who underwent a gallbladder removal operation often have a tube -shaped tube after the operation.

After the introduction of the dye into the biliary tree of the patient, a number of X -rays are then taken. X -ray films are then read by a radiologist, a doctor who is an expert in the interpretation of testing results. When there is no blocking, the dye usually flows continuously. His absence in any part of the billiard tree often indicates an obstacle. The causes of the bile ducts other include cysts, tumors or cancer in the area and bile ducts.

before subjugating the procedurePatients are usually instructed to affect at least eight hours. There may also be a sedation during the process. The whole procedure usually takes about 30 minutes to one hour. The test results are often released two to three days later.

Some risks are involved in cholangiography. This includes pain at the site of injections and bleeding, which can manifest itself as bloody stools. The use of a special dye can also be toxic to the kidneys. Other side effects of cholangiography include vomiting, dry mouth, blurring vision and serious allergic reactions.
