    Study Notes

    GI Studies

    • The barium transit time to the stomach is 5-10 minutes.
    • Glucagon is used to relax smooth muscles of the GI tract in GI studies.

    Body Habitus

    • Individuals with thicker body parts are described as endomorphic.
    • Asthenic body habitus is characterized by a slender build and is found in 10% of the population.
    • Hyposthenic body habitus is characterized by a thin, delicate build and is found in 5% of the population.

    Esophageal Conditions

    • Achalasia is characterized by a failure of the lower esophagus sphincter muscle to relax.
    • The most common cause of esophagitis is reflux esophagitis.
    • Esophageal cancer is best diagnosed using endoscopy and biopsy.
    • Photodynamic therapy involves laser-activated chemicals to destroy esophageal tumors.
    • Zenker's Diverticulum is a large outpouching of the esophagus just above the upper esophageal sphincter.

    Varices and Positioning

    • If varices are suspected, the patient should be placed in the Trendelenburg position (head down).

    Medications

    • Metoclopramide (Maxolon) enhances gastric peristalsis to aid in the passage of contrast material during GI studies.
    • Buscopan is used to relax smooth muscles of the GI tract in GI studies.
    • Medications like atropine and anticholinergics have side effects including blurred vision and dry mouth.

    Barium Suspension

    • The weight measure for barium in 100 grams of suspension is 30-40%.
    • The weight measure for barium in 100 ml of suspension is 30-40%.
    • UGI Single contrast typically uses a 50-70% barium suspension.
    • UGI Double contrast typically uses a 100-150% barium suspension.
