Diagnosis is made by barium swallow; surgical repair is rarely required.

Types of Diverticula

There are several types of esophageal diverticula, each of different origin:

Symptoms and Signs of Esophageal Diverticula

A Zenker diverticulum fills with food that might be regurgitated when the patient bends or lies down. Aspiration pneumonitis may result if regurgitation is nocturnal. Rarely, the pouch becomes large, causing dysphagia and sometimes a palpable neck mass.

Traction and epiphrenic diverticula are rarely symptomatic, although their underlying cause may be.

Diagnosis of Esophageal Diverticula

  • Barium swallow

All diverticula are diagnosed by videotaped barium swallow and often confirmed on upper endoscopy.

Treatment of Esophageal Diverticula

  • Usually none

  • Sometimes surgical resection

Specific treatment is usually not required, although resection is occasionally necessary for large or symptomatic diverticula. Diverticula associated with motility disorders require treatment of the primary disorder. For example, case reports suggest doing a cricopharyngeal myotomy when resecting a Zenker diverticulum. There are also emerging endoscopic treatment options for diverticulectomy.
