Digestive System Diagnostic and Therapeutic Procedure Flashcards
Liver Function Tests (LFTs)
Group of blood tests that evaluate liver injury, liver function, and conditions often associated with the biliary tract. Evaluates liver enzymes, bilirubin, and proteins produced by the liver.
Endoscopy
Visual examination of a cavity or canal using a flexible fiberoptic instrument called a endoscope
Upper GI: esophagoscopy gastroscopy duodenoscopy Lower GI: colonoscopy sigmoidoscopy proctoscopy
Serum Bilirubin
Measurement of the level of bilirubin in the blood
Stool Culture
Test to identify microorganisms or parasites present in feces
stool guiac
applying a substance called guaiac to a stool sample to detect presence of occult blood in the feces; also called Hemoccult (trade name of a modified guaiac test)
barium enema
Radiographic examination of the rectum and colon following enema administration of barium sulfate (contrast medium) into the rectum; also called lower GI series
Barium swallow
Radiographic examination of the esophagus, stomach, and small intestine following oral administration of barium sulfate (contrast medium); also called esophagram, and upper GI series
cholecystography
radiographic images taken of the gallbladder after administration of a contrast material containing iodine, usually in the form of a tablet
computed tomography
in the digestive system, CT scans are used to view the gallbladder, bowel, liver, bile ducts, and pancreas. It is also used to diagnose tumors, cysts, inflammation, abscesses, perforation, bleeding, and obstructions.
endoscopic retrograde cholangiopancreatography (ERCP)
Endoscopic procedure that provides radiographic visualization of the bile and pancreatic ducts to identify partial or total obstructions, as well as stones, cysts, and tumors.
percutaneous transhepatic cholangiography (PTCP)
Radiographic examination of bile duct structures. Contrast medium is injected through a needle passed through the skin (percutaneous) and through the liver (transhepatic) directly into the hepatic duct
sialography
radiologic examination of the salivary glands and ducts (with or without contrast medium)
ultrasonography
Test that uses high frequency sound waves (ultrasound) to analyze the reflected echoes from anatomical structures and convert them into an image on a video monitor; also called ultrasound, sonography, echo, and echogram
abdominal ultrasound is used for the abdominal aorta, liver, gallbladder, bile ducts, pancreas, kidneys, ureters, and bladder
Liver Biopsy
use of a large-bore needle to remove a core of liver tissue for histological examination
nasogastric intubation
procedure that involves insertion of a nasogastric tube through the nose into the stomach to relieve gastric distention by removing gas, good, or gastric secretions; to instill medication, food, or fluids, or to obtain a specimen for lab analysis
