Zenker’s diverticula are one or more pouches that develop in the throat, just above the esophageal sphincter. The upper esophageal sphincter is a muscular band with the wall of the esophagus that helps control the flow of food or liquid into or out of the esophagus. These diverticula are created when part of the inner esophageal lining bulges through the muscular wall of the throat. They frequently occur in an area known as Killian’s triangle. These pouches usually are present of the left side due to the shape of the esophagus. Zenker’s diverticula occur most often in northern European countries and those whose heritage is northern European, including the US, Canada and Australia. It is rare in Asia. It is one and a half times more common among men than women, and almost always occurs in older individuals.
Causes of Zenker's Diverticulum
The cause of Zenker’s diverticulum are unknown. However, several theories exist as to its etiology. They include abnormal timing during swallowing that causes the cricopharyngeal muscle to close when it should open. Other abnormalities involving the cricopharyngeal muscles, including incomplete relaxation, loss of elasticity, atrophy and spasm have been suggested as possible causes of this disorder.
Signs and Symptoms of Zenker's Diverticulum
Symptoms of Zenker’s diverticulum include dysphasia, or problems with swallowing. Regurgitation of food may occur, even long after it has been consumed. Bad breath may develop. As food makes its way into the adjacent airway, coughing and aspiration may occur. Weight loss may develop.
