Zenker's

Zenker's diverticulum is a diverticulum of the mucosa of the pharynx, just above the cricopharyngeal muscle (i.e., above the upper sphincter of the esophagus). It was named after Friedrich Albert von Zenker, a German pathologist.

Signs and Symptoms

The most common symptoms of Zenker's diverticulum are dysphagia (difficulty swallowing), regurgitation (undigested food that is not acidic), coughing, aspiration, and weight loss.

Causes

Zenker's diverticulum is caused by increased pressure in the hypopharynx and a weakness in the pharyngeal wall. This pressure can be due to a variety of factors, including age, diet, and certain medical conditions.

Diagnosis

Zenker's diverticulum can be diagnosed through a variety of methods, including barium swallow, endoscopy, and manometry.

Treatment

Treatment options for Zenker's diverticulum include surgery, endoscopic treatment, and dietary changes.
