A stent for a clogged up bile duct is generally put in using a procedure known as an Endoscopic Retrograde Cholangiopancreatography (ERCP). An ERCP makes use of a tube with a camera on the end that is passed down your throat.
Before the ERCP, it is advised to tell your medical team about any types of medicines that you are taking, mainly medicine to thin your blood (like that of warfarin or clopidogrel) or for diabetes (like metformin or insulin). Your medical team is going to tell you how to take these medicines before your procedure of ERCP.
You will be asked not to consume or drink for at least six hours before the ERCP – although you could be in a position to have small sips of water up to two hours before. This is to ensure that your stomach and duodenum are unfilled. You would also have a sedative before the stent is placed in. This is going to make you sleepy and relaxed, but would not send you to sleep. And for your information there are options in stents like Plastic biliary stent and metal biliary stents.
The flexible tube having a camera and light on the end (an endoscope) is inserted into your mouth and passed down the throat into your stomach. The camera displays the inside of your body on a screen. The stent is placed inside the bile duct making use of a small wire. When the stent is in the proper place the wire gets removed. The stent must unblock the bile duct that should then drain normally. The ERCP generally takes thirty to forty minutes.
Getting a stent put in through the skin (PTC)
Some people are there who may not be able to get a stent put in with an ERCP. Instead, the stent gets passed through the tummy wall and liver, and into bile duct, making use of a thin needle. This is known as a Percutaneous Transhepatic Cholangiogram (PTC). A PTC is mostly used if the blockage is high up in bile duct, near the area of liver.
You will possess a sedative to make you sleepy. You shall also have injections of a local anaesthetic into the stomach area or lower chest. This shall make it numb, so that you cannot feel anything. The PTC needle is put into the bile duct making use of x-ray pictures on a computer screen. Dye gets injected into the needle so that the obstruction shows up on the screen. A wire gets put into the needle and used to guide the stent into position. An x-ray is then going to be taken of your bile duct to ensure that the stent is in the right place.
What takes place afterwards?
After the procedure of an ERCP you may have a blood test to find out that the ERCP has not triggered any problems such as inflammation of pancreas. You shall be told when you can consume and eat again (normally after four to six hours). You would be told who to contact in case you have any issues after the ERCP.
Thus, endoscopic biliary stenting is a common and successful method of treatment.it is better to have knowledge about it before you undergo it.
