Pharyngeal Pouch (Zenkers Diverticulum)
Description
A pouch that develops in the walls of the lower throat. When swallowing food it enters the pouch. As the pouch fills it can press on the esophagus causing obstruction. Food can spill into the airway and cause an aspiration. Patients can spit up undigested food that was eaten many hours before. Pills can also become lodged in the pouch. The disorder is most often found in those over 50.
Symptoms
Spitting up undigested food many hours after eating, difficulty swallowing, weight loss, painful swallowing, cough, multiple bouts of pneumonia.
Tests
A history and physical exam will be performed. The disorder can be diagnosed with an esophagram, EGD (Esophagogastroduodenoscopy), or CT scan.

Treatment
Therapy depends on the extent of the defect and the health of the patient. Treatment includes repair of the pouch done either through an endoscope or with conventional surgery.
