    Study Notes

    Overview of Gastrointestinal Tract

    • The gastrointestinal tract includes the esophagus, stomach, small intestine, large intestine, colon, rectum, biliary tract, gallbladder, liver, and pancreas.
    • The patient history and physical examination are essential in evaluating GI disorders.

    Symptoms of GI Dysfunction

    • Common symptoms include heartburn, abdominal pain, dyspepsia, nausea, vomiting, diarrhea, constipation, and gastrointestinal bleeding.
    • Symptoms may also indicate malabsorption, hepatitis, and GI infection.

    Patient History

    • A comprehensive patient history is crucial in evaluating patients with digestive complaints.
    • A clear, detailed, chronologic account of the patient's problems should be obtained.
    • The onset of the problem, its manifestations, and its progression should be determined.

    Diagnostic Procedures

    • Serum chemistry panel provides valuable information on fluid and electrolyte status, nutritional status, and abdominal organ function.
    • Imaging studies, such as radiography, CT, and radionuclide scans, are useful in visualizing the liver, spleen, bile ducts, gallbladder, and gut.
    • Endoscopy, including upper GI endoscopy, colonoscopy, and sigmoidoscopy, can be used for diagnostic and therapeutic purposes.
    • ERCP (endoscopic retrograde cholangiopancreatography) is used to evaluate and treat diseases of the biliary tree and pancreas.

    Preparation for Diagnostic Procedures

    • Patients should fast for 8-12 hours before procedures such as enteroclysis, colonoscopy, and sigmoidoscopy.
    • Bowel cleansing agents may be administered before colonoscopy and sigmoidoscopy.
    • Topical pharyngeal anesthetics and sedating agents may be used to improve patient acceptance and ease of procedures.

    Imaging Studies

    • Radiographic imaging can detect cysts, abscesses, tumors, and obstructions in the GI tract.
    • Radionuclide bleeding scans can detect hemorrhages and assist in localization.
    • HIDA scan can demonstrate normal gallbladder function.
    • CT scans can be used to evaluate the liver, spleen, and bile ducts.

    Conclusion

    • Evaluation of the GI tract begins with a careful history and comprehensive physical examination.
    • Diagnostic procedures, including imaging studies and endoscopy, should be used in a deliberate and thoughtful manner to establish the correct diagnosis and appropriate management.
