Duodenal biliary drainage
|
|
Duodenal biliary drainageA procedure used to diagnose gallstones when suspicion is high but other tests are negative. A thin tube is passed through a nostril down the throat, through the esophagus and stomach, into the duodenum. Once the tube is in place, a synthetic hormone related to cholecystokinin is injected IV. It causes the gallbladder to contract and squeeze out bile into the duodenum. The bile then is sucked up through the tube and examined for the presence of cholesterol and pigment particles under a microscope. A modification of duodenal biliary drainage involves collection of bile through an endoscope at the time of EGD (esophagogastroduodenoscopy) or ERCP (endoscopic retrograde cholangio-pancreatography).
RELATED TERMS--------------------------------------
Diagnose
To identify a disease.
Gallstones
Presence or formation of gallstones.
Esophagus
The organ that connects the mouth to the stomach. Also called gullet.
Stomach
The organ between the esophagus and the small intestine. The stomach is where digestion of protein begins.
Duodenum
The first part of the small intestine.
Hormone
A chemical substance formed in the body that is carried in the bloodstream to affect another part of the body; an example is thyroid hormone, produced by the thyroid gland in the neck, which affects growth, temperature regulation, metabolic rate, and other body functions.
Cholecystokinin
A hormone released in the small intestine. Causes muscles in the gallbladder and the colon to tighten and relax.
Gallbladder
The storage sac for bile, located below the liver.
Contract
A written, dated, and signed agreement between two or more involved parties that sets out any arrangements on delegation and distribution of tasks and obligations and, if appropriate, on financial matters. The protocol may serve as the basis of a contract.
Bile
Fluid made by the liver and stored in the gallbladder. Bile helps break down fats and gets rid of wastes in the body.
Cholesterol
A substance similar to fat that is found in the blood, muscles, liver, brain, and other body tissues.
Microscope
A microscope (Greek: micron = small and scopos = aim) is an instrument for viewing objects that are too small to be seen by the naked or unaided eye. The science of investigating small objects using such an instrument is called microscopy, and the term microscopic means minute or very small, not easily visible with the unaided eye. In other words, requiring a microscope to examine.
Duodenal
Having to do with the duodenum.
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.
Endoscope
A small, flexible tube with a light and a lens on the end. It is used to look into the esophagus, stomach, duodenum, colon, or rectum. It can also be used to take tissue from the body for testing or to take color photographs of the inside of the body. Colonoscopes and sigmoidoscopes are types of endoscopes.
ERCP
Endoscopic retrograde cholangiopancreatography.
SIMILAR TERMS--------------------------------------
Duodenal
Having to do with the duodenum.
Duodenal ulcer
An ulcer in the lining of the first part of the small intestine (duodenum).
Duodenitis
An irritation of the first part of the small intestine (duodenum).
Duodenum
The first part of the small intestine.
PREVIOUS AND NEXT TERMS--------------------------------------
Ductus
A duct or walled passageway suitable for the conveyance of air or, more often in the body, liquids.
Ductus arteriosus
A key arterial shunt (ductus) in fetal life. Before birth, blood pumped from the heart through the pulmonary artery toward the lungs is shunted into the aorta. This arterial shunt is a short vessel called the ductus arteriosus. When the shunt is open, it is said to be patent.
Ductus, patent
Failure for the ductus arteriosus, an arterial shunt in fetal life, to close on schedule. Before birth, blood pumped from the heart through the pulmonary artery toward the lungs is shunted into the aorta. This arterial shunt is a short vessel called the ductus arteriosus. When the shunt is open, it is said to be patent.
Dumdum fever
Also called kala-azar, a chronic, potentially fatal parasitic disease of the viscera (the internal organs) due to infection by an agent called Leishmania donovani.
Dummy
In science experiments, a substance without any active ingredient, a placebo.
Duodenal biliary drainage
Duplication
Part of a chromosome in duplicate, a particular kind of mutation (change) involving the production of one or more copies of any piece of DNA, including a gene or even an entire chromosome.
Dupuytren contracture
A localized formation of scar tissue in the palm of the hand. The scarring accumulates in a tissue called the fascia beneath the skin of the palm that normally covers the tendons that pull the fingers grip. As Dupuytren contracture progresses, more of the fascia becomes thickened and shortened. Dimpling and puckering of the skin over the area eventually occur.
Dura
The outermost, toughest, and most fibrous of the three membranes (meninges) covering the brain and the spinal cord. Dura is short for dura mater (from the Latin for hard mother). Also called the pachymeninx (singular) or pachymeniges (plural).
Durable power of attorney
This is a type of advance medical directive in which legal documents provide the power of attorney to another person in the case of an incapacitating medical condition.
Dural
Pertaining to the dura.
