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
anastomosis
surgical joining of two ducts, vessels, or bowel segments to allow flow from one to another
ileorectal: surgical connection of ileum and rectum after total colectomy
intestinal: surgical connection of two portions of the intestines; also called enteroenterostomy
vertical banded gastroplasty
a type of bariatric surgery in which the upper stomach near the esophagus is stapled vertically to reduce it to a small pouch. A band is then inserted that restricts food consumption and delays its
Roux-en-Y gastric bypass
Stomach is first stapled to decrease it to a small pouch. Next, the jejunum is shortened and connected to the small stomach pouch, causing the base of the the duodenum leading from the nonfunctioning portion of the stomach to form a Y configuration. This configuration decreases the pathway of food through the intestine, thus reducing absorption of calories and fats
lithotripsy
crushing a stone and eliminating its fragments either surgically or using ultrasonic shock waves
Extracorporeal shockwave: use of shock waves as a noninvasive method to break up stones in the gallbladder and biliary ducts
polypectomy
excision of a polyp.
When polyps are discovered during sigmoidoscopy or colonoscopy, they are excised for microscopic tissue examination for abnormal or cancerous cells
pyloromyotomy
Incision of the longitudinal and circular muscles of the pylorus; used to treat hypertrophic pyloric stenosis
