ZENKER DIVERTICULA Meaning and
Definition
-
Zenker diverticulum, also known as pharyngoesophageal diverticulum, is a type of a diverticulum that affects the lining of the pharynx, or the upper part of the esophagus. It is a pouch-like outpouching or sac that develops in the posterior wall of the esophagus, typically just above the upper esophageal sphincter. Zenker diverticula are acquired conditions, meaning they develop later in life rather than being present from birth.
The exact cause of Zenker diverticula is not fully understood, but it is believed to be related to a combination of factors including muscle weakness and increased pressure in the pharynx during swallowing. Symptoms may include difficulty swallowing (dysphagia), a sensation of something stuck in the throat (globus sensation), regurgitation of undigested food, bad breath, and chronic coughing. As the diverticulum grows larger, it may become more symptomatic.
If Zenker diverticulum is suspected, diagnosis is typically made through a combination of medical history, physical examination, and imaging tests such as barium swallow studies, X-rays, or endoscopy. Treatment options for Zenker diverticula depend on the severity of symptoms. In many cases, conservative management with dietary changes and swallowing techniques may be sufficient to alleviate symptoms. However, in more severe cases, surgical intervention such as diverticulopexy or diverticulectomy may be necessary to remove or reposition the diverticulum and reduce symptoms.
Early diagnosis and appropriate treatment of Zenker diverticula are vital to prevent complications such as recurrent aspiration pneumonia or malnutrition. Therefore, it is important for individuals experiencing symptoms consistent with Zenker diverticulum to seek medical evaluation
