    Study Notes

    Esophagus Structure and Function

    • Esophagus is a muscular tube connecting the throat to the stomach, approximately 25cm (10in) long.
    • It extends from the pharynx to the stomach, about 4cm (1.6in) below the diaphragm.
    • Two sphincters regulate movement: upper esophageal (UES/oropharyngeal) and lower esophageal (LES/gastroesophageal).

    Esophageal Sphincters

    • UES and LES prevent reflux (backflow) of food and fluids.
    • Disorders such as structural defects, inflammation, obstruction, or cancer can impact nutritional intake.

    Esophageal Motility

    • Esophageal contractions move food and liquids toward the stomach.
    • Relaxation of the LES allows passage into the stomach.
    • LES contraction prevents reflux.

    Esophageal Disorders

    • Gastroesophageal reflux disease (GERD): Common condition with gastric content and enzyme backflow into esophagus.

      • Normal amount of reflux is possible.
      • Excessive reflux due to factors (incompetent LES, pyloric stenosis, hiatal hernia, pressure) irritates esophageal tissue, hindering clearance.
      • Leads to chronic esophageal irritation and potential complications.
    • Hiatal hernia: Part of the stomach protrudes through the diaphragm. Can contribute to GERD.

    • Esophageal varices: Enlarged veins in the esophagus.

    GERD Treatment and Complications

    • Primarily treated with diet and lifestyle changes, followed by medication (antacids, H2-receptor antagonists, proton pump inhibitors), or surgery.
    • Untreated GERD can lead to inflammation, erosion, and long-term complications such as esophageal strictures (scarring), Barrett's esophagus (precancerous condition), or esophageal adenocarcinoma (cancer).
