Final Flashcards
visual examination of a cavity or canal using a flexible fiberoptic instrument called an endoscope
endoscopy
endoscopy of the esophagus (esophagoscopy), stomach (gastroscopy), and duodenum (duodenoscopy)
upper GI
endoscopy of the colon (colonoscopy), sigmoid colon (sigmoidoscopy), and rectum and anal canal (proctoscopy)
lower GI
panel of blood tests that identify the specific virus- hep A (HAV), hep B (HBV), or hep C (HCV)- causing hepatitis by testing serum using antibodies to each of these antigens
hepatitis panel
group of blood tests that evaluate liver injury, liver function, and conditions often associated with the biliary tract
liver function tests (LFT)
measurement of the level of bilirubin in the blood
serum bilirubin
test to identify microorganisms or parasites present in feces
stool culture
applying a substance called guaiac to a stool sample to detect presence of occult blood in the feces; also called hemoccult
stool guaiac
radiographic exam of the rectum and colon following enema administration of barium sulfate (contrast medium) into the rectum; also called lower GI series
barium enema
radiographic exam of the esophagus, stomach, and small intestine following oral administration of barium sulfate. aka esophagram and upper GI series
barium swallow
rad images taken of the gallbladder after admin of a contrast material containing iodine, usually in the form of a tablet
cholecystography
imaging technique achieved by rotating an x-ray emitter around the area to be scanned and measuring the intensity of transmitted rays from different angles
computed tomography (CT)
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
endoscopic retrograde cholangiopancreatography (ERCP)
radiographic examination of bile duct structures
percutaneous transhepatic choliangography (PTCP)
radiologic examination of the salivary glands and ducts
sialography
test that uses high frequency sound waves to analyze the reflected echos from anatomical structures and convert them into an image on a video monitor
ultrasonography
US visualization of the abdominal aorta, liver, gallbladder, bile ducts, pancreas, kidneys, ureters, and bladder
abdominal ultrasonography
representative tissue sample removed from a body site for microscopic examination, usually to establish a diagnosis
biopsy (bx)
use of a large-bore needle to remove a core of liver tissue for histological examination
liver biopsy
procedure that involves insertion of a nasogastric tube through the nose into the stomach to relieve gastric distention by removing gas, food, or gastric secretions
nasogastric intubation
surgical joining of two ducts, vessels, or bowel segments to allow flow from one to another
anastomosis
surgical connection of the ileum and rectum after total colectomy
iliorectal anastomosis
surgical connection of two portions of the intestines; aka enteroenterostomy
intestinal anastomosis
