  Biliary atresia



Biliary atresia

    A condition present from birth in which the bile ducts inside or outside the liver do not have normal openings. Bile becomes trapped in the liver, causing jaundice and cirrhosis. Without surgery the condition may cause death.

RELATED TERMS
--------------------------------------

Condition
The term "condition" has a number of biomedical meanings including the following: 1.An unhealthy state, such as in "this is a progressive condition." 2.A state of fitness, such as "getting into condition." 3.Something that is essential to the occurrence of something else; essentially a "precondition." 4.As a verb: to cause a change in something so that a response that was previously associated with a certain stimulus becomes associated with another stimulus; to condition a person, as in behavioral conditioning.

Bile
Fluid made by the liver and stored in the gallbladder. Bile helps break down fats and gets rid of wastes in the body.

Liver
The largest organ in the body. The liver carries out many important functions, such as making bile, changing food into energy, and cleaning alcohol and poisons from the blood.

Jaundice
A condition in which the skin and the whites of the eyes become yellow, urine darkens, and the color of stool becomes lighter than normal. Jaundice occurs when the liver is not working properly or when a bile duct is blocked.

Cirrhosis
A chronic liver condition caused by scar tissue and cell damage. Cirrhosis makes it hard for the liver to remove poisons (toxins) like alcohol and drugs from the blood. These toxins build up in the blood and may affect brain function.

Surgery
Treating diseases or other medical conditions by operating on a patient to remove or repair parts of the body.

Death
1. The end of life. The cessation of life. (These common definitions of death ultimately depend upon the definition of life, upon which there is no consensus.) 2. The permanent cessation of all vital bodily functions. (This definition depends upon the definition of "vital bodily functions.") See: Vital bodily functions. 3. The common law standard for determining death is the cessation of all vital functions, traditionally demonstrated by "an absence of spontaneous respiratory and cardiac functions." 4. The uniform determination of death.



SIMILAR TERMS
--------------------------------------

Biliary
Having to do with the gallbladder, bile ducts, or bile. The biliary system itself consists of the gallbladder and bile ducts and, of course, the bile.

Biliary compression
Abnormal pressure on the biliary tree compromising the normal drainage of bile.

Biliary decompression
A procedure done to remove pressure on the biliary tree and permit the normal drainage of bile.

Biliary sand
Biliary sand is a term mostly used by surgeons when they remove the gallbladder to describe uncountable, small particles in bile that are visible to the naked eye. Biliary sand may be looked upon as a stage in the growth of the particles that comprise sludge (which are microscopic and not visible to the naked eye) and gallstones, which are large enough to be counted easily. The composition of biliary sand varies but is similar to the composition of gallstones. The most common components of biliary sand are cholesterol crystals and calcium salts.

Biliary sludge
A mixture of microscopic particulate matter in bile that occurs when particles of material precipitate from bile. (Bile is the fluid that is made by the liver. It is stored in the gallbladder until after a meal when it passes out of the gallbladder and through the common bile duct into the intestine to help digest fat in the meal.)

Biliary stricture
A narrowing of the biliary tract from scar tissue. The scar tissue may result from injury, disease, pancreatitis, infection, or gallstones. See also stricture.

Biliary system

Bilious
The adjective for bile, bilious has three meanings. It means of or relating to bile. By extension, bilious means suffering from liver dysfunction (and especially excessive secretion of bile). And, further by extension, it is indicative of a peevish ill-natured disposition.

Biliousness
"A term used in the 18th and 19th centuries pertaining to bad digestion, stomach pains, constipation, and excessive flatulence (passing gas). The quantity or quality of the bile was thought to be at fault for the condition. Hence, the name ""biliousness."" (""Bilious"" derives from the French ""bilieux,"" which in turn came from ""bilis,"" the Latin term for ""bile."") Biliousness was generally laid to high living. The ""cure"" was moderation and frequent visits to the doctor."

Bilirubin
The orange-yellow pigment of bile, the green fluid that aids in digestion and that is secreted by the liver. Bilirubin is formed mainly by hemoglobin breakdown at the end of red cell life and eventually most of it leaves the body in the feces. Two types are in the blood. Water insoluble or unconjugated bilirubin refers to the pigment before it reaches the liver. In the liver it is converted to the water-soluble or conjugated bilirubin which is excreted into the bile.

Bilivist
Bilivist is a prescription or over-the-counter drug which is (or once was) legal in the United States and possibly in other countries. Active ingredient(s): ipodate sodium.
