Biliary Tract Neoplasms
Biliary Tract Diseases
Tumors or cancer of the gallbladder.
A malignant tumor arising from the epithelium of the BILE DUCTS.
Bile Ducts, Extrahepatic
Bile Duct Neoplasms
Tumors or cancer of the BILE DUCTS.
Bile Ducts, Intrahepatic
Inflammation of the biliary ductal system (BILE DUCTS); intrahepatic, extrahepatic, or both.
Surgical removal of the GALLBLADDER.
Ampulla of Vater
Common Bile Duct
Cholangiopancreatography, Endoscopic Retrograde
Fiberoptic endoscopy designed for duodenal observation and cannulation of VATER'S AMPULLA, in order to visualize the pancreatic and biliary duct system by retrograde injection of contrast media. Endoscopic (Vater) papillotomy (SPHINCTEROTOMY, ENDOSCOPIC) may be performed during this procedure.
An imaging test of the BILIARY TRACT in which a contrast dye (RADIOPAQUE MEDIA) is injected into the BILE DUCT and x-ray pictures are taken.
Bile Duct Diseases
Hepatic Duct, Common
Urinary Tract Infections
Inflammatory responses of the epithelium of the URINARY TRACT to microbial invasions. They are often bacterial infections with associated BACTERIURIA and PYURIA.
Common Bile Duct Diseases
Generally refers to the digestive structures stretching from the MOUTH to ANUS, but does not include the accessory glandular organs (LIVER; BILIARY TRACT; PANCREAS).
Congener of FLUOROURACIL with comparable antineoplastic action. It has been suggested especially for the treatment of breast neoplasms.
Cholangiopancreatography, Magnetic Resonance
INFLAMMATION of the PANCREAS. Pancreatitis is classified as acute unless there are computed tomographic or endoscopic retrograde cholangiopancreatographic findings of CHRONIC PANCREATITIS (International Symposium on Acute Pancreatitis, Atlanta, 1992). The two most common forms of acute pancreatitis are ALCOHOLIC PANCREATITIS and gallstone pancreatitis.
Respiratory Tract Infections
Fibers that arise from cells within the cerebral cortex, pass through the medullary pyramid, and descend in the spinal cord. Many authorities say the pyramidal tracts include both the corticospinal and corticobulbar tracts.
Incision of Oddi's sphincter or Vater's ampulla performed by inserting a sphincterotome through an endoscope (DUODENOSCOPE) often following retrograde cholangiography (CHOLANGIOPANCREATOGRAPHY, ENDOSCOPIC RETROGRADE). Endoscopic treatment by sphincterotomy is the preferred method of treatment for patients with retained or recurrent bile duct stones post-cholecystectomy, and for poor-surgical-risk patients that have the gallbladder still present.
Pathological processes of the LIVER.
Hemorrhage in or through the BILIARY TRACT due to trauma, inflammation, CHOLELITHIASIS, vascular disease, or neoplasms.
Sphincter of Oddi
Technetium Tc 99m Lidofenin
A Y-shaped surgical anastomosis of any part of the digestive system which includes the small intestine as the eventual drainage site.
Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
Common Bile Duct Neoplasms
The transference of a part of or an entire liver from one human or animal to another.
Tumors or cancer of the LIVER.
Excision of the gallbladder through an abdominal incision using a laparoscope.
Solitary or multiple collections of PUS within the liver as a result of infection by bacteria, protozoa, or other agents.
Antineoplastic Combined Chemotherapy Protocols
A structurally-related family of small, multimeric proteins that are secreted in the mucosa of mammalian epithelial tissues. A variety of proteins are classed under this heading including some secretoglobin subtypes that appear unique to a particular mammalian species, and others whose functions differ between species.
Ducts that collect PANCREATIC JUICE from the PANCREAS and supply it to the DUODENUM.
A claudin subtype that takes part in maintaining the barrier-forming property of TIGHT JUNCTIONS. Claudin-4 is found associated with CLAUDIN-8 in the KIDNEY COLLECTING DUCT where it may play a role in paracellular chloride ion reabsorption.
Surgery of the smooth muscle sphincter of the hepatopancreatic ampulla to relieve blocked biliary or pancreatic ducts.
Tumors or cancer of the PANCREAS. Depending on the types of ISLET CELLS present in the tumors, various hormones can be secreted: GLUCAGON from PANCREATIC ALPHA CELLS; INSULIN from PANCREATIC BETA CELLS; and SOMATOSTATIN from the SOMATOSTATIN-SECRETING CELLS. Most are malignant except the insulin-producing tumors (INSULINOMA).
An inorganic and water-soluble platinum complex. After undergoing hydrolysis, it reacts with DNA to produce both intra and interstrand crosslinks. These crosslinks appear to impair replication and transcription of DNA. The cytotoxicity of cisplatin correlates with cellular arrest in the G2 phase of the cell cycle.
Tumor Markers, Biological
Molecular products metabolized and secreted by neoplastic tissue and characterized biochemically in cells or body fluids. They are indicators of tumor stage and grade as well as useful for monitoring responses to treatment and predicting recurrence. Many chemical groups are represented including hormones, antigens, amino and nucleic acids, enzymes, polyamines, and specific cell membrane proteins and lipids.
A bile pigment that is a degradation product of HEME.
A class of statistical procedures for estimating the survival function (function of time, starting with a population 100% well at a given time and providing the percentage of the population still well at later times). The survival analysis is then used for making inferences about the effects of treatments, prognostic factors, exposures, and other covariates on the function.
