Cycle II, Module C, Course 6 (GIT and abdominal problems)
Prof. MUDr. Jiří Horák
Seminar 1. Introduction. Examination procedures in GIT and abdominal
problems
Introduction
- clinical and epidemiologic significance of gastrointestinal and abdominal
problems
- history
- typical gastrointestinal and abdominal symptomes, signs and syndromes
- physical examination
- auxilliary examinations
Gastrointestinal symptoms and signs
- abdominal pain & colic
- weight loss
- anorexia
- nausea & vomiting
- heartburn = retrosternal burning pain
- dysphagia & odynophagia
- diarrhoea
- constipation
- flatulence
- biliary dyspepsia and colic
- disorders of hematopoiesis and hemocoagulation, gastrointestinal bleeding
- jaundice
- hepatic encephalopathy
- abdominal swelling, water retention and ascites
- pruritus (itching)
- hepatorenal syndrome (functional renal failure)
- portal hypertension and esophageal varices bleeding
Genitourinary symptoms and signs
- change in appearance of the urine
- urinary obstruction
- anuria (<50 ml urine daily), oliguria, polyuria, nocturia, polakisuria
- menstrual problems
- lumbar pain
- renal colic
Laboratory findings
a) nonspecific markers of inflammation or malignant growth
- erythrocyte sedimentation rate
- C-reactive protein
- protein electrophoresis

Cycle II, Module C, Course 6 (GIT and abdominal problems)
Prof. MUDr. Jiří Horák
- blood count
- serum complement concentration (decreased in arthritis, vasculitis, nephritis)
- other acute-phase proteins (fibrinogen, ferritin, haptoglobin, coeruloplasmin,
alpha-1 antitrypsin etc.) are not used for inflammatory activity assessment
b) functional examination
- gastric chemistry
- pancreozymin-secretin test
- bentiromide test
- chromoexcretory tests of liver function (bromphtalein, indocyanine green,
rose bengal, IDA-derivatives)
- metabolic tests of liver function: galactose test, antipyrine test
- pH-metry
- stool examination for fat and residues
- xylose test
- beta-carotene
- hemocoagulation
c) tests for GIT bleeding
- benzidine test
- Hemoccult
d) protein exudation into the GIT
- radioactive chromalbumin test
e) the so-called liver function tests
- bilirubin
- ALT, AST
- GMT, ALP
- other tests useful in diagnosis and monitoring of liver disease:
blood count, serum protein, hemocoagulation tests, iron, creatinine, glucose,
triglycerides, cholesterol, ammonia, bile acids
f) pancreas examination
- amylase
- lipase
g) urine chemistry
- bilirubin
- urobilinogen
- protein
- glucose
- keton bodies
h) antibodies and autoantibodies (cf. table Antibodies and autoantibodies in
autoimmune hepatitis)
- ANA
- ASMA
- AMA - typically in primary biliry cirrhosis
- ANCA (p, c)

- against thyroid tissue
- against gastric mucosa
- against intrinsic factor
- LKM antibodies etc.
i) serology and molecular biology of viral hepatitis
- hepatitis A
- hepatitis B
- hepatitis C
- hepatitis D
- hepatitis E
- hepatitis G
- TTV-hepatitis
j) tests for Helicobacter pylori
- histology
- antibodies
- urease test
- breath tests
k) microbiological examination
- stools
- ascites
- bile
- urine
- other
l) serological tests in microbiological diagnostics
m) tests in metabolic diseases
- hepatic porphyrias
- Wilson's disease
- genetic hemochromatosis
- cystic fibrosis
- alpha-1 antitrypsin deficiency
n) tumour markers
- alpha-fetoprotein - hepatocellular carcinoma
- carcinoembryonic antigen - colorectal carcinoma
- Ca 19-9 - pancreatic carcinoma
- Ca 125 - gynecological carcinomas, carcinoma of the liver, pancreas and
lungs
- gastrin - gastrinoma
- C-peptide – insulinoma
Imaging methods, endoscopy and biopsy
- abdominal sonography
- endosonography
- X-ray of the esophagus
