    disorder of the tube that carries food from the mouth to the stomach (esophagus), which affects the ability of the esophagus to move food toward the stomach.
  2. adenoma
    a benign epithelial tumor in which the cells form recognizable glandular structures or in which the cells are derived from glandular epithelium.
  3. adynamic ileus
    intestinal obstruction due to inhibition of bowel motility
  4. Charcot's triad
    • for cholangitis (inflammation of the bile ducts)
    • jaundice, fever (with chills), abdominal pain (usually RUQ)
  5. cholecystectomy
    surgical removal of the gall bladder
  6. cholecystitis
    painful inflammation of the gall bladder wall
  7. choledocholithiasis
    presence of a gallstone in the common bile duct
  8. cholestasis
    condition caused by rapidly developing (acute) or long-term (chronic) interruption in the excretion of bile (a digestive fluid that helps the body process fat). The term is taken from the Greek chole, bile, and stasis, standing still.
  9. cirrhosis
    chronic degenerative disease in which normal liver cells are damaged and are then replaced by scar tissue.
  10. defecation
    the evacuation of fecal matter from the rectum.
  11. dumping syndrome
    nausea, weakness, sweating, palpitation, syncope, often a sensation of warmth, and sometimes diarrhea, occurring after ingestion of food in patients who have undergone partial gastrectomy.
  12. dyspepsia
    painful, difficult, or disturbed digestion, which may be accompanied by symptoms such as nausea and vomiting, heartburn, bloating, and stomach discomfort.
  13. encephalopathy
    • any degenerative brain disease
    • hepatic encephalopathy
  14. fatty liver
    the collection of excessive amounts of triglycerides and other fats inside liver cells.
  15. fistula
    a permanent abnormal passageway between two organs in the body or between an organ and the exterior of the body
  16. gastroparesis
    Nerve damage of the stomach that delays or stops stomach emptying, resulting in nausea, vomiting, bloating, discomfort, and weight loss
  17. H. Pylori
    A gram negative rod-shaped bacterium that lives in the tissues of the stomach and causes inflammation of the stomach lining
  18. hematochezia
    passage of bloody stools
  19. hematemesis
    vomiting blood
  20. hemolysis
    The destruction or dissolution of red blood cells, with release of hemoglobin
  21. lithotripsy

  22. melena
    The passage of black tarlike stools containing blood that has been acted on by the intestinal juices.
  23. Murphy's sign
    a test for gallbladder disease in which the patient is asked to inhale while the examiner's fingers are hooked under the liver border at the bottom of the rib cage. The inspiration causes the gallbladder to descend onto the fingers, producing pain if the gallbladder is inflamed. Deep inspiration can be very much limited.
  24. obstruction
    any obstruction that results in failure of the contents of the intestine to progress through the lumen of the bowel. The most common cause is a mechanical blockage resulting from adhesions, impacted feces, tumor of the bowel, hernia, intussusception, volvulus, or the strictures of inflammatory bowel disease. Obstruction may also be the result of paralytic ileus. Obstruction of the small bowel may cause severe pain, vomiting of fecal matter, dehydration, and eventually a drop in blood pressure. Obstruction of the colon causes less severe pain, marked abdominal distension, and constipation. Radiographic examination may reveal the level of obstruction and its cause. Treatment includes the evacuation of intestinal contents by means of an intestinal tube. Surgical repair is sometimes necessary. Fluid balance and electrolyte balance are restored by carefully monitored IV infusion. Nonnarcotic analgesics are usually prescribed to prevent the decrease in intestinal motility that often accompanies the administration of narcotic analgesics
  25. occult blood
    that present in such small quantities that it is detectible only by chemical tests or by spectroscopic or microscopic examination.
  26. odynophagia

  27. pellagra
    disorder brought on by a deficiency of the nutrient called niacin or nicotinic acid, one of the B-complex vitamins.
  28. peripheral neuropathy
    Beriberi is a disease caused by a deficiency of thiamine (vitamin B1) that affects many systems of the body, including the muscles, heart, nerves, and digestive system. Beriberi literally means "I can't, I can't" in Singhalese, which reflects the crippling effect it has on its victims. It is common in parts of southeast Asia, where white rice is the main food. In the United States, beriberi is primarily seen in people with chronic alcoholism.
  29. placebo response
    any dummy medical treatment; originally, a medicinal preparation having no specific pharmacological activity against the patient's illness or complaint given solely for the psychophysiological effects of the treatment; more recently, a dummy treatment administered to the control group in a controlled clinical trial in order that the specific and nonspecific effects of the experimental treatment can be distinguished.
  30. reflux esophagitis

  34. ALT
    • (alanine aminotransferase)
    • an enzyme that catalyzes the reversible transfer of an amino group from alanine to α-ketoglutarate to form pyruvate and glutamate. Normally present in many tissues and body fluids, especially in the liver, it is released into the serum as a result of tissue injury; the serum concentration is increased particularly when there is acute damage to hepatic cells, as in viral or toxic hepatitis, infectious mononucleosis, and obstructive jaundice.
  35. amylase
    an enzyme that catalyzes the hydrolysis of starch into simpler compounds. The α-a's occur in animals and include pancreatic and salivary amylase
  36. AST
    • (aspartate transaminase)
    • an enzyme normally present in body tissues, especially in the heart and liver; it is released into the serum as the result of tissue injury, hence the concentration in the serum (SGOT) may be increased in disorders such as myocardial infarction or acute damage to hepatic cells.
  37. CBC
    • (complete blood count)
    • A routine analysis performed on a sample of blood taken from the patient's vein with a needle and vacuum tube. The measurements taken in a CBC include a white blood cell count, a red blood cell count, the red cell distribution width, the hematocrit (ratio of the volume of the red blood cells to the blood volume), and the amount of hemoglobin (the blood protein that carries oxygen). CBCs are a routine blood test used for many medical reasons, not only for AIDS patients. They can help the doctor determine if a patient is in advanced stages of the disease
  38. CMP
    • (comprehensive metabolic panel)
    • A battery of analytes–albumin, alk phos, AST, BUN, calcium, chloride, glucose, potassium, sodium, total protein–which are measured to establish a baseline and detect metabolic disorders
  39. decubitus x-ray of abdomen
    • included in acute abdominal series
    • to view any free air in the abdomen
  40. direct bilirubin
    elevations of direct (conjugated) bilirubin typically result from obstruction either within the liver (intrahepatic) or a source outside the liver (e.g. gallstones or a tumor blocking the bile ducts)
  41. indirect bilirubin
    elevated levels of indirect (unconjugated) bilirubin are usually caused by liver cell dysfunction (e.g. hepatitis)
  42. ESR
    erythrocyte sedimentation rate: the rate at which red blood cells settle in a vertical tube, used to detect the presence of disease
  43. fecal antigen assay
    a test that utilizes an enzyme immunoassay format, with multiple monoclonal antibodies to detect Helicobacter pylori antigens
  44. hepatitis serum markers
    Hepatitis B serologic testing involves measurement of several hepatitis B virus (HBV)-specific antigens and antibodies. Different serologic "markers" or combinations of markers are used to identify different phases of HBV infection and to determine whether a patient has acute or chronic HBV infection, is immune to HBV as a result of prior infection or vaccination, or is susceptible to infection.
  45. LDH
    • Lactate dehydrogenase is of medical significance because it is found extensively in body tissues, such as blood cells and heart muscle.
    • main use of the test for lactate dehydrogenase (LDH) is as a general indicator of the existence and severity of acute or chronic tissue damage and, sometimes, as a monitor of progressive conditions such as kidney disease, liver disease, and some cancers. It may be used as a tumor marker for testicular cancer and other germ cell tumors such as ovarian cancer to help stage, determine prognosis, and monitor treatment as well as in other cancers, including lymphoma, melanoma, and neuroblastoma.
    • LDH used to be ordered to help diagnose and monitor a heart attack, but the troponin test has largely replaced LDH in this role. LDH isoenzymes may be used in differential diagnosis to help determine which organs are likely to be involved.
  46. LFTs
    Liver function tests, or LFTs, include tests for bilirubin, a breakdown product of hemoglobin, and ammonia, a protein byproduct that is normally converted into urea by the liver before being excreted by the kidneys. LFTs also commonly include tests to measure levels of several enzymes, which are special proteins that help the body break down and use (metabolize) other substances. Enzymes that are often measured in LFTs include gamma-glutamyl transferase (GGT); alanine aminotransferase (ALT or SGPT); aspartate aminotransferase (AST or SGOT); and alkaline phosphatase (ALP). LFTs also may include prothrombin time (PT), a measure of how long it takes for the blood to clot.
  47. lipase

These drugs are among the most widely sold drugs in the world, and are generally considered effective. The vast majority of these drugs are benzimidazole derivatives, but promising new research indicates the imidazopyridine derivatives may be a more effective means of treatment. High dose or long-term use of PPIs carries a possible increased risk of bone fractures.

A radiopaque substance is instilled directly into the duct, and serial x-ray films are taken. It is useful in identifying partial or total obstruction of these ducts, as well as stones, benign strictures, cysts, ampullary stenosis, anatomic variations, and malignant tumors.
  84. esohageal manometry
    a diagnostic study to assess the competence of the lower esophageal sphincter. A catheter sheathed with a water-filled balloon is inserted nasally and advanced into the esophagus; a series of measurements reflecting esophageal resting pressures are taken as the catheters are moved.
  85. esophagram
    • barium swallow
    • A technique in which a radiocontrast "milkshake" of barium sulfate is swallowed to detect benign or malignant lesions of the pharynx, oesophagus, stomach and small intestine and evaluate the integrity of the swallowing mechanism; the progress of the barium is followed radiographically to detect filling defects—e.g., places where a normal outline of barium should be seen but is not.
  86. MRI
