Ch. 12 Diagnostic Tests & Procedures Flashcards
biopsy (Bx)
removal and microscopic study of tissue for pathological examination
incisional biopsy
removal of a portion of a lesion
excisional biopsy
removal of an entire lesion
needle biopsy
percutaneous removal of tissue or fluid using a special, hollow needle (e.g., for liver biopsy)
endoscopy
examination within a body cavity with a flexible endoscope for diagnosis or treatment; used in the gastrointestinal tract to detect abnormalities and to perform procedures such as biopsy, excision of lesions, and therapeutic interventions
colonoscopy
examination of the colon using a flexible colonscope
proctoscopy
examination of the rectum and anus with a proctoscope
sigmoidoscopy
examination of the sigmoid colon with a rigid or flexible sigmoidoscope
esophagogastroduodenoscopy (EGD)
examination of the esophagus, stomach and duodenum with a flexible endoscope
capsule endoscopy
examination of the small intestine made by a tiny video camera placed inside a capsule and then swallowed
endoscopic retrograde cholangiopancreatography (ERCP)
endoscopic procedure including x-ray fluoroscopy to examine the ducts of the liver, gallbladder, biliary ducts, and pancreas
laparoscopy
examination of the abdominal cavity with a laparoscope for diagnostic purposes and/or to perform surgery
upper gastrointestinal (GI) series
x-ray of the esophagus, stomach, and duodenum after the patient has swallowed a contrast medium
barium swallow
x-ray of the esophagus only
fluoroscopy
x-ray imaging with a fluorescent screen to visualize structures in motion (e.g., during a barium swallow)
small bowel series
x-ray examination of the small intestine; generally done in conjunction with an upper GI series
lower gastrointestinal (GI) series; barium enema
x-ray imaging of the colon after administration of an enema containing a contrast medium
cholangiogram
x-ray image of the bile ducts; often performed during surgery
cholecystogram
x-ray image of the gallbladder obtained after oral ingestion of iodine
abdominal sonogram
ultrasound image of the abdomen to detect disease or deformity in organs and vascular structures
endoscopic ultrasonography (EUS)
images produced using a sonographic transducer within an endoscope to evaluate abnormalities of the upper and lower gastrointestinal tracts and adjacent structures; also used to guide needle biopsy of tissue and in determining the stage of a malignancy
stool culture & sensitivity (C&S)
isolation of a stool specimen in a culture medium to identify disease-causing organisms; if organisms are present, the drugs to which they are sensitive are listed
stool occult blood study
chemical test of a stool specimen to detect the presence of blood; positive findings indicate bleeding in the gastrointestinal tract
