Epiphrenic diverticula can cause esophageal regurgitation due to pouch volume and pressure gradients. Surgical treatment like resection or imbrication yields good results, but asymptomatic patients may not need surgery.

Area of Science:

  • Gastroenterology
  • Surgical Endoscopy

Background:

  • Epiphrenic diverticula are outpouchings in the esophagus.
  • Understanding their mechanism and treatment is crucial for patient outcomes.

Purpose of the Study:

  • To clarify the mechanism of esophageal regurgitation in epiphrenic diverticula.
  • To evaluate surgical and non-surgical treatment methods.

Main Methods:

  • Esophagogastroduodenoscopy, esophageal motility, and cineradiographic studies were performed.
  • Simultaneous motility and cineradiographic studies in two patients correlated symptoms with pressure changes.
  • Nineteen patients underwent surgery; six remained asymptomatic.

Main Results:

  • Retrograde movement of diverticular contents depends on pouch volume and pressure gradients.

  • Esophageal reflux height and symptoms are influenced by these factors and lower esophageal sphincter pressure (LESP).
  • Surgical outcomes (resection/imbrication) were excellent or good in 10 long-term followed patients.

    • Conclusions:

    • Asymptomatic epiphrenic diverticula do not necessitate surgery.
    • Resection or imbrication are effective treatments, with a preference for the abdominal approach.
    • Myotomy is contraindicated with gastroesophageal reflux or low LESP.
