    Study Notes

    Approach to Disorders of the Gastrointestinal Tract

    • The gastrointestinal tract (GIT) consists of the oral cavity, oropharynx, esophagus, stomach, small intestine, large intestines, rectum, anus, liver, and pancreas.

    Learning Objectives

    • Understand how to restrain and perform a comprehensive clinical examination, including history-taking and physical examination, to identify clinical problems and involved body systems.
    • Demonstrate a rational, evidence-based problem-solving approach to common presentations in companion animal practice.
    • Perform clinical reasoning, including differential diagnoses and further investigations.
    • Understand how to take appropriate samples and request appropriate tests.
    • Interpret and appraise laboratory reports and clinical data for clinical case management.
    • Formulate appropriate treatment, patient care, control, and prevention plans, including euthanasia.
    • Critically review and evaluate evidence to support practicing evidence-based veterinary medicine.

    Gastrointestinal Disease

    • Gastrointestinal disease is very common, with many cases self-limiting.
    • Identify cases requiring further investigation/treatment.
    • Be aware of clinical presentations of serious illness requiring immediate attention.
    • Thorough history-taking is essential, as reported symptoms may not fully represent the true situation (e.g., vomiting vs. regurgitation vs. dysphagia).
    • Careful and comprehensive physical examinations are needed as various parts of the GIT are not always easy to assess.
    • Excellent client communication is crucial.

    Approaching a Case

    • Evaluate if immediate treatment is necessary.
    • Gather a history.
    • Create a problem list.
    • Perform physical exams.
    • Implement symptomatic treatment.
    • Assess if resolution occurs, and act accordingly.

    Approaching a Case - Problem-Based Approach

    • Address life-threatening conditions immediately.
    • Evaluate possible systemic diseases.
    • Consider potential differential diagnoses.
    • Formulate a treatment plan.

    Anorexia

    • Anorexia is a loss or lack of appetite to eat (not eating, not wanting to eat, not able to eat).
      • Partial (hyporexia) or complete.
      • True anorexia: decreased appetite, with no interest in eating.
      • Pseudoanorexia: secondary anorexia, hungry but unable to eat due to pain, unpalatable diets, or environmental stress.

    Oral Cavity

    • Components: Lips and oral mucosa, palate, tongue, teeth, mandible, maxilla, and salivary glands.

    Clinical Signs

    • General clinical signs: Pseudoanorexia(jaw abnormality, pain), unwillingness to play/pick up toys, hypersalivation, failure to gain weight, halitosis, ceased grooming.
    • Other clinical signs: Possible pain or movement abnormalities in the jaw (abnormal movement), pain, unwilling to pick up toys/play ball, hypersalivation, poor or decreased weight gain, problems with oral hygiene (halitosis), ceased grooming.
