Zenker's Diverticulum refers to a diverticulum (outpouching) of the mucosa of the pharynx, just above the cricopharyngeal muscle.
As with the formation of diverticula in general, the increased pressure within the lumen of the pharynx, causes the mucosa of the weakest part of the pharyngeal wall to balloon outwards. It is believed that in the case of Zenker's diverticula formation, a poorly coordinated swallowing mechanism, resulting in impaired relaxation and contraction of the pharyngeal muscles, causes this excessive pressure build up.
What are the Symptoms?
Many people may remain asymptomatic. Others may experience the following symptoms:
• Sensation of a "lump in the neck"
• Dysphagia (difficulty or pain on swallowing)
• "Gurgling" sound on swallowing
• Regurgitation of undigested food
• Recurrent cough
• Halitosis (bad breath)
How is it Diagnosed?
The gold standard for diagnosis is a simple barium swallow.
Treatment
A small diverticulum may not require any treatment. Larger ones, especially if symptomatic, should be treated. Surgical techniques include:
• Surgical resection of the diverticulum
• Endoscopic stapling
