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.
