What is the most common disorder of the biliary system?

Gallstone disease is the most common disorder affecting the biliary system, the body's system of transporting bile. Gallstones are solid, pebble-like masses that form in the gallbladder or the biliary tract (the ducts leading from the liver to the small intestine).

How do you fix a bile duct problem?

In some cases, surgery is required to bypass the blockage. The gallbladder will usually be surgically removed if the blockage is caused by gallstones. Your provider may prescribe antibiotics if an infection is suspected. If the blockage is caused by cancer, the duct may need to be widened.

Why do bile ducts get injured?

Variation from the normal anatomy of the bile ducts is a primary reason the ducts get inadvertently injured during some types of surgery.

What is an aberrant duct?

Aberrant ducts are a common variation from the normal anatomy that comprises the biliary system. Aberrant ducts are not anatomically structured the way they should be. For example, the ducts may abnormally join the wrong ducts, so that bile does not flow properly.

Tests. Several types of tests are done to diagnose abnormalities and diseases of the biliary system. Liver function tests: A blood sample is taken, and a lab test is performed to evaluate certain enzymes and protein levels to see how the liver is functioning.

Where does the bile duct go?

The common bile duct passes through the pancreas before it empties into the duodenum. The lower portion of the CBD joins the pancreatic duct before entering the duodenum. This is where pancreatic juices (containing digestive enzymes) enter the biliary system.

What are the parts of the bile duct system?

The ductules come together to form small tubes called ducts. These merge into larger ducts and then into the left and right hepatic ducts. All of these ducts within the liver are called intrahepatic bile ducts.

Where do bile ducts go?

About the bile ducts. The bile ducts are a series of thin tubes that go from the liver to the small intestine. Their main job is to allow a fluid called bile to go from the liver and gallbladder into the small intestine, where it helps digest the fats in food.

What is the duct that empties into the small intestine called?

This combined duct is called the common bile duct. The common bile duct passes through part of the pancreas before it joins with the pancreatic duct and empties into the first part of the small intestine (the duodenum) at the ampulla of Vater.

What are the different types of bile duct cancer?

Based on where the cancers start (see the picture below), they're grouped into 3 types: Intrahepatic bile duct cancers. Perihilar (also called hilar) bile duct cancers. Distal bile duct cancers.

Where does bile duct cancer start?

Intrahepatic bile duct cancers. These cancers start in the smaller bile duct branches inside the liver. Sometimes they're confused with cancers that start in the liver cells ( hepatocellular carcinomas ), and they are often treated the same way.

Which ducts exit the liver and join to form the common hepatic duct?

The left and right hepatic ducts exit the liver and join to form the common hepatic duct in an area called the hilum. Lower down, the gallbladder (a small organ that stores bile) is joined to the common hepatic duct by a small duct called the cystic duct. This combined duct is called the common bile duct.

A biliary obstruction is a blockage of the bile ducts. The bile ducts carry bile from the liver and gallbladder through the pancreas to the duodenum, which is a part of the small intestine. Bile is a dark-green or yellowish-brown fluid secreted by the liver to digest fats. After you eat, the gallbladder releases bile to help in digestion ...

What happens to the gallbladder after eating?

After you eat, the gallbladder releases bile to help in digestion and fat absorption. Bile also helps clear the liver of waste products. Obstruction of any of these bile ducts is referred to as a biliary obstruction. Many of the conditions related to biliary obstructions can be treated successfully.

What is the treatment for gallstones?

Can biliary strictures cause liver enzymes to rise?

Patients with mild biliary strictures may not show any symptoms, but the stricture causes abnormalities in the blood and a rise in some of the liver enzymes. When the stricture becomes more pronounced, symptoms start to develop. Cleveland Clinic is a non-profit academic medical center.

What is the bile duct?

A bile duct is part of the portal triad, which enters the liver through invagination of Glisson's capsule at the hilum. According to the vascular anatomy, the right and left hemiliver are drained by a right and a left hepatic duct, respectively.

Which ducts can join the left hepatic duct?

In 4% of patients, a right sectoral duct can join the left hepatic duct (3% posterior and 1% anterior). The right hepatic duct drains all segments of the right hemiliver (segments 5, 6, 7, and 8). The ducts of segments 6 and 7 form the posterior right hepatic duct, and those of segments 5 and 8 form the anterior right hepatic duct.

What are the three hepatic arteries?

Embryologically, there are three hepatic arteries: a left hepatic artery that arises from the left gastric artery, a middle hepatic artery from the celiac axis, and a right hepatic artery from the superior mesenteric artery. Usually, the left and right branches disappear and the middle artery remains as the future proper hepatic artery. The middle artery divides into two (right and left) branches at the lower part of the hepatic pedicle. The left branch is taken away from the main bile duct. Multiple combinations of the embryologic arteries have been described (Figure 4). One arterial variation is important for the surgery of cholangiocarcinoma: if a right hepatic artery is in place, it is then possible to perform an extended left hepatic hepatectomy to segment 1 or to segments 1, 5, and 8 without dissecting the hilum. Arising from the superior mesenteric artery, this right hepatic artery runs in every case at the posterior side of the portal trunk and joins the right margin edge at a variable height.

What is the left hepatic duct?

The left hepatic duct drains segments 2, 3, and 4 of the left hemiliver. The “normal” confluence comprises a duct formed from ducts of segments 2 and 3 and one or more ducts from segment 4. The segment 3 duct follows the left horn of the Rex recessus and joins the segment 2 duct above the segment 2 portal branch (at the level of the curve of the hilar part in the posterior-anterior portion of the portal branch). This duct is 2.5 cm long, from 2 to 5 cm, depending on the size of the posterior margin of the quadrate lobe. Being extrahepatic in this portion, it runs transversely in the hilum, from left to right. Running first above and behind the left portal branch, it crosses the superior edge and joins the right hepatic duct to form the biliary confluence. For the left hepatic duct 1, this normal anatomy is reported in 82%. In 4% of patients, a right sectoral duct can join the left hepatic duct (3% posterior and 1% anterior).

Which duct forms distally to the choledochus?

Anterior aspect of the biliary anatomy in the hepatic pedicle. The common hepatic duct receives the cystic duct and then forms distally to the choledochus. This distinction is arbitrary, because the cystic duct joins at a variable site, which must be carefully considered during gallbladder operation.

Where is the hilar duct located?

A communicating arcade between the right and left arterial system is located within the hilar plate, and originated from the segment 4 artery and the right branch of the middle hepatic artery 7.

Which duct is posterior?

The segment 1 ducts are posterior, running above the portal branch and joining the corresponding bile duct on its posterior margin. In the event of hilar bile duct cancer, which may spread along the bile duct, especially into the dorsal ducts, caudate lobectomy and segmentectomy 4 are routinely necessary for resecting the corresponding bile duct and for complete extirpation of the tumor.
