Q

Zenker’s. mechanism?

A

Cause: upper esophageal sphincter dysfunction and esophageal dysmotility  increased intraluminal pressure above the cricopharyngeus muscle eventually results in herniation of the mucosa through an area of weakness –> posterior herniation between the fibers of cricopharyngeal muscle.

Impaired cricopharyngeal relaxation

A pulsion, not traction pseudodiverticulitis
