Biliary Drainage: What Conditions Does It Treat?

Sunday, 27 April 2014 09:56 PM

Gallstones and bile stones are common. Bile stones are solid substances formed of substances like cholesterol in the gallbladder or bile duct. They lead to various unwanted symptoms and complications, including cancer. These bile stones form when cholesterol particles form hard crystals, which further leads to blockage of the bile duct in a condition called cholangitis. Cholangitis can lead to a more serious disease such as cancer. Serious complications can further arise from a gallbladder cancer or a bile duct cancer.
Bile stones or any other conditions due to bile stones are treated by a process called biliary drainage. Let us discuss biliary drainage and the efficacy of the biliary drainage procedure in treating various conditions.

Bile Stones and Cancer Are Conditions Treated by Biliary Drainage

Bile stones form in the bile duct. Cholesterol stones are primary bile stones, accounting for about 80 percent of stones formed in the bile duct. These yellow colored stones can also form in the gallbladder. About 10 percent of stones formed in the gallbladder are bile stones.
Bile stones formed in the bile duct generate severe conditions like cholangitis, which is a blockage of the bile duct. Cholangitis or a blockage in the bile duct can lead to serious conditions including bile duct cancer. Apart from cholangitis and cancer, other conditions caused due to bile stones include jaundice and infections. Bile stones can be treated by biliary drainage. Thus, biliary drainage also treats the conditions related to bile stones like bile duct cancer, cholangitis, and jaundice.

Biliary Drainage: How Does It Work?

Biliary drainage is the most important treatment available for bile stones or cancer of the bile duct. PTBD or the percutaneous transhepatic biliary drainage is another name for biliary drainage. In this procedure, drainage of bile duct is conducted via a small catheter of plastic, which is internally passed across the narrowed bile duct and externally connected to a plastic drainage bag. The procedure is pain free, except the anesthesia used when it is positioned. Some discomfort can be experienced but clears soon.
The entire process of biliary drainage of the bile duct might take one to two hours and analgesia and deep sedation may be used while carrying out this process. Along with the catheter, there is a stent placed in the initial session. After a couple of days, the catheter may be removed and stent left in the position after its full expansion.

Biliary Drainage: Prognosis and Risks

The technical success of biliary drainage depends on the expertise of the doctors, i.e. the experience and skill of the radiologist performing the drainage. However, clinical success rate is usually 90 percent while considering the treatment of bile stones or cancer of the bile duct via biliary drainage.

The risks involved in biliary drainage might include post-drainage bleeding, infections, or mild pain.
