  Bile - Wikipedia, the free encyclopedia
Bile salts combine with phospholipids to break down fat globules in the process of emulsification by associating its hydrophobic side with lipids and the hydrophilic side with water.
Since bile increases the absorption of fats, it is an important part of the absorption of the fat-soluble vitamins D, E, K and A.
Yellow bile and fl bile were two of the four vital fluids or humours of ancient and medieval medicine (the other two were phlegm and blood).

 Cholesterol and Bile Metabolism
Synthesis of bile acids is one of the predominant mechanisms for the excretion of excess cholesterol.
Within the intestines the primary bile acids are acted upon by bacteria and converted to the secondary bile acids, identified as deoxycholate (from cholate) and lithocholate (from chenodeoxycholate).
bile acids and phospholipids solubilize cholesterol in the bile, thereby preventing the precipitation of cholesterol in the gallbladder.

 Payton, Bile Duct Cancer & Sclerosing Cholangitis - Cancer information on MedicineNet.com
Bile duct cancer is a rare disease in which there are malignant cells in the tissues of the extrahepatic bile duct.
The bile duct is a tube that connects the liver and the gallbladder to the small intestine.
This is a chronic disorder of the liver in which the bile ducts outside the liver (the extrahepatic bile ducts) and often the bile ducts inside the liver (the intrahepatic bile ducts) become inflamed, thickened (sclerotic), narrowed, and finally obstructed.

 Secretion of Bile and the Role of Bile Acids In Digestion
Bile is a complex fluid containing water, electrolytes and a battery of organic molecules including bile acids, cholesterol, phospholipids and bilirubin that flows through the biliary tract into the small intestine.
Bile acids are derivatives of cholesterol synthesized in the hepatocyte.
The cholesterol-derived portion of a bile acid has one face that is hydrophobic (that with methyl groups) and one that is hydrophilic (that with the hydroxyl groups); the amino acid conjugate is polar and hydrophilic.

 eMedicine - Bile Duct Strictures : Article Excerpt by: William R Brugge, MD
The injury may be a single acute event, such as damage to the bile ducts during surgery or trauma to the abdomen; a recurring condition, such as pancreatitis or bile duct stones; or a chronic disease, such as primary sclerosing cholangitis (PSC).
Malignant strictures usually are the result of either a primary bile duct cancer (ie, causing a narrowing of the bile duct lumen and obstructing the flow of bile) or extrinsic compression of the bile ducts by a neoplasm in an adjacent organ, such as the gallbladder, pancreas, or liver.
One major category of bile duct strictures is postoperative bile duct stricture, which usually occurs as a result of a technical mishap during cholecystectomy, causing bile duct injury.

 Bile duct - Wikipedia, the free encyclopedia
Bile, required for the digestion of food, is excreted by the liver into passages that carry bile toward the hepatic duct, which joins with the cystic duct (carrying bile to and from the gallbladder) to form the common bile duct, which opens into the intestine.
Blockage of the bile duct by a cancer, gallstones, or scarring from injury prevents the bile from being transported to the intestine and the active ingredient in the bile (bilirubin) instead accumulates in the blood.
Jaundice is commonly caused by conditions such as pancreatic cancer, which causes blockage of the bile duct passing through the cancerous portion of the pancreas; cholangiocarcinoma, cancer of the common bile duct; blockage by a stone in patients with gallstones; and from scarring after injury to the bile duct during gallbladder removal.

 Dr. Koop - Bile duct obstruction   (Site not responding. Last check: 2007-10-18)
The bile ducts carry bile from the liver to the gallbladder, and from the gallbladder to the small intestine.
Bile passes out of the liver through the bile ducts and is concentrated and stored in the gallbladder until it is released into the small intestine after a meal to help with fat digestion.
When the bile ducts become blocked, bile accumulates in the liver, and jaundice (yellow color of the skin) develops due to the accumulation of bilirubin in the blood.

 Bile reflux
Less well known is bile reflux, which occurs when bile — a digestive fluid produced in the liver — flows upward (refluxes) from the small intestine into the stomach and esophagus.
Bile reflux can be difficult to distinguish from acid reflux — the signs and symptoms are similar, and the two conditions frequently occur at the same time.
Bile is a greenish-yellow fluid that's essential for digesting and absorbing fats and for eliminating worn-out red blood cells and certain toxins from your body.

 Bile definition - Medical Dictionary definitions of popular medical terms
Bile: Bile is a yellow-green fluid that is made by the liver, stored in the gallbladder and passes through the common bile duct into the duodenum where it helps digest fat.
The principal components of bile are cholesterol, bile salts, and the pigment bilirubin.
Cholesterol is normally kept in liquid form by the dissolving action of the bile salts; an increased amount of cholesterol in the bile overwhelms the dissolving capacity of the bile salts and leads to the formation of cholesterol gallstones.

 Bile reflux - MayoClinic.com
Less well known is bile reflux, which occurs when bile — a digestive fluid produced in the liver —; flows upward (refluxes) from the small intestine into the stomach and esophagus.
Bile reflux often accompanies acid reflux, and together they're a formidable team, inflaming the lining of the esophagus and potentially increasing the risk of esophageal cancer.
Instead, bile reflex is most often managed with certain medications or, in severe cases, with surgery.

 Bile Duct Cancer
When bile is needed, such as after a fatty meal, it is released into the small intestine via another duct which connects the gallbladder to the small intestine.
Bile duct cancer tends to spread into the adjacent liver, along the bile duct surface and through the lymph system to lymph nodes in the region of the liver.
The cause is unknown although people with chronic inflammatory processes such as ulcerative colitis or parasitic infections of the bile ducts, or with congenital abnormalities of the bile ducts are at higher risk for developing this cancer.

 Bile Acid Sequestrants, medications to lower cholesterol on MedicineNet.com
Bile acid sequestrants such as cholestyramine (Questran), colestipol (Colestid), and colesevelam (Welchol) are medications for lowering LDL cholesterol.
Bile acid sequestrants bind bile acids in the intestine and cause more of the bile acids to be excreted in the stool.
Bile acid sequestrants are not absorbed into the body and therefore they do not have systemic side effects (affecting other organs).

 About Extrahepatic Bile Duct Cancer
The chance of recovery (prognosis) and choice of treatment depends on the location of the cancer in the bile duct, the stage of the cancer (whether it is only in the bile duct or has spread to other places), and the patient’s general health.
If the cancer is small and is only in the bile duct, a doctor may remove the whole bile duct and make a new duct by connecting the duct openings in the liver to the intestine.
If the cancer is blocking the small intestine and bile builds up in the gallbladder, the doctor may do surgery to go around (bypass) all or part of the small intestine.
