What is Zenker’s Diverticulum?
Zenker ’s diverticulum ( pharyngeal pouch / hypopharyngeal diverticulum/ pharyngoesophageal diverticulum ) is a diverticulum which is formed from the mucous membrane of the throat and is situated above the cricopharyngeal muscular tissue , which is present above the upper sphincter of the esophagus . Zenker ’s diverticulum is a false diverticulum , as it does not imply all the layers of the esophageal wall . Zenker ’s diverticulum was name by Friedrich Albert von Zenker , who was a German diagnostician , in 1877 .
Causes of Zenker’s Diverticulum
The principal case of Zenker ’s Diverticulum is think to be malfunctioning of the cricopharyngeal muscle due to the aging process . Neurologic medical conditions , such as a stroke , also can get malfunctioning of the cricopharyngeal muscle . Excessive force per unit area in the lower pharynx do balloon out of the weakest part of the pharyngeal bulwark leave in formation of diverticulum , which can be many centimeter in diameter .
According to current inquiry , occlusive mechanisms are thought to fiddle an important role in formation of Zenker ’s Diverticulum , such as impaired easiness , uncoordinated get down , and spasm of the cricopharyngeus muscle ; all these thing leave to increased pressure in the distal pharynx which leads to its hernia through the point in time of least resistance . This period is have it off as Killian ’s triangle , which is situate superior to the cricopharyngeus muscle and low to the substandard constrictor muscle . This cause outpouching of the ulterior pharyngeal wall , which is just above the esophagus .
