Q
amylase
A
Enzyme (-ase) secreted by the pancreas and salivary glands to digest
starch (amyl/o).
17
Q
bile
A
Digestive juice made in the liver and stored in the gallbladder. It breaks
up (emulsifies) large fat globules. Bile originally was called gall (Latin
bilis, meaning gall or anger), probably because it has a bitter taste. It is
composed of bile pigments (colored materials), cholesterol, and bile
salts.

amylase and lipase tests
Tests for the levels of amylase and lipase enzymes in the blood.
Increased levels are associated with pancreatitis.
98
liver function tests (LFTs)
Tests for the presence of enzymes and bilirubin in blood.
LFTs are performed on blood serum (clear fluid that remains after blood has
clotted). Examples of LFTs are tests for ALT (alanine transaminase) and AST
(aspartate transaminase). ALT and AST are enzymes present in many tissues.
Levels are elevated in the serum of patients with liver disease. High ALT and AST
levels indicate damage to liver cells (as in hepatitis).
Alkaline phosphatase (alk phos) is another enzyme that may be elevated in
patients with liver, bone, and other diseases.
Serum bilirubin levels are elevated in patients with liver disease and jaundice.
A direct bilirubin test measures conjugated bilirubin. High levels indicate liver
disease or biliary obstruction. An indirect bilirubin test measures unconjugated
bilirubin. Increased levels suggest excessive hemolysis, as may occur in a newborn.
99
stool guaiac test or
| Hemoccult test
Test to detect occult (hidden) blood in feces.
This is an important screening test for colon cancer. Guaiac (GWĪ-ăk) is a chemical
from the wood of trees. When added to a stool sample, it reacts with any blood
present in the feces. See Figure 6-2B.
100
cholangiography
X-ray examination of the biliary system performed after injection of
contrast into the bile ducts.
In percutaneous transhepatic cholangiography, the contrast medium is injected
using a needle placed through the abdominal wall into the biliary vessels of the
liver. In endoscopic retrograde cholangiopancreatography (ERCP) (Figure 6-4A),
contrast medium is administered through an oral catheter (tube) and then passes
through the esophagus, stomach, and duodenum and into bile ducts. This
procedure helps diagnose problems involving the bile ducts, gallbladder, and
pancreas.
101
HIDA scan
Radioactive imaging procedure that tracks the production and flow of
bile from the liver and gallbladder to the intestine.
HIDA stands for hepatobiliary iminodiacetic acid. Cholescintigraphy is another
name for this test, which determines if the gallbladder is functioning properly.
102
gastric bypass or bariatric
| surgery
Reducing the size of the stomach and diverting food to the jejunum
(gastrojejunostomy).
bariatric (bar/o = weight; iatr/o = treatment
103

inserted through small incisions in the abdomen.
104
