What is the cholangiogram catheter?

Cholangiograms are imaging techniques that allow the doctor to look specifically at the pipes that release the bile into the digestive system. Some of these techniques require inserting a small tube into the pipeline in the procedure. This tube is called a cholangiogram catheter.

Some health conditions such as bile stones and cancer can cause blockages or other problems in the gall magazines. Instead of having to undergo reconnaissance surgery so that the doctor can identify the presence and cause of pipe problems, the patient must now have only minimally invasive imaging techniques. Two main types of imaging procedures on the bile ducts require the use of cholangiogram catheters.

The catheter is a specific form of hoses for medical purposes. It allows the fluid to either drain from the body or enter the body. In the case of a cholangiogram catheter, the fluid must go to the body at a specific point. Usually, the cholangiograms are narrow catheters of diameter.

This fluid is a dye. DyeEvys on the final image from the imaging technology and helps to identify areas of interest. For example, the blocked pipes will not let it dye, so the dye is displayed only on one side. The dye can help doctors to determine blocking, leaks or unusually narrow pipes that could indicate the disease.

Endoscopic retrograde cholangiopancreatography (ERCP) is one imaging technique that uses the cholangiogram of the catheter. Pro tento postup lékař vloží kameru na dlouhou trubici dolů trávicí systém do horní části tenkého střeva. The thin cholangiogram catheter is then placed directly in the main bile ducts. It then passes through the catheter to emphasize the area of ​​interest.

Percutaneous transhepatic cholangiography (PTC) is a more invasive procedure that includes inserting a needle into the abdomen and into B into the bile pipes. This needle is used as a guide conductor for a catheter tube that slips over it forEsna location. Then the doctor fills the dye with the catheter into the channels and emphasizes the area of ​​interest with the current of the dye.

Both ERCP and PTC cholangiogram catheters are temporarily inserted as dye delivery systems. After the procedures, the catheters are removed. Like ERCP and PCT, magnetic resonance imaging can also find pipe problems, and this technique requires no dye inserting or invasive tube insertion.
