What is cbd obstruction

The following tests may be used to investigate a possible blocked bile duct:

If the blockage is not corrected, it can lead to life-threatening infection and a dangerous buildup of bilirubin.

Outlook (Prognosis)

Symptoms may include:

Bile is a liquid released by the liver. It contains cholesterol, bile salts, and waste products such as bilirubin. Bile salts help your body break down (digest) fats. Bile passes out of the liver through the bile ducts and is stored in the gallbladder. After a meal, it is released into the small intestine.

Prevention

Be aware of any risk factors you have, so that you can get prompt diagnosis and treatment if a bile duct becomes blocked. The blockage itself may not be preventable.

Symptoms

Causes, incidence, and risk factors

Complications include infections, sepsis, and liver disease such as biliary cirrhosis from untreated obstruction.

Signs and tests

For patient education resources, see the Digestive Disorders Center and Cholesterol Center, as well as Gallstones and Cirrhosis.

Disorders of the biliary tract affect a significant portion of the worldwide population, and the overwhelming majority of cases are attributable to cholelithiasis (gallstones). In the United States, 20% of persons older than 65 years have gallstones and 1 million newly diagnosed cases of gallstones are reported each year.

Pathophysiology

Extrahepatic obstruction to the flow of bile may occur within the ducts or secondary to external compression. Overall, gallstones are the most common cause of biliary obstruction. Other causes of blockage within the ducts include malignancy, infection, and biliary cirrhosis. External compression of the ducts may occur secondary to inflammation (eg, pancreatitis) and malignancy. Regardless of the cause, the physical obstruction causes a predominantly conjugated hyperbilirubinemia.

Biliary obstruction refers to the blockage of any duct that carries bile from the liver to the gallbladder or from the gallbladder to the small intestine. This can occur at various levels within the biliary system. The major signs and symptoms of biliary obstruction result directly from the accumulation of bilirubin and bile salts in the blood and the failure of bile to reach its proper destination.
