Endoscopic Treatment of Zenker's Diverticulum. A Review of The Literature

Abstract

Zenker's diverticulum (ZD) is a sac-like evagination of the mucosa and submucosa through the Killian triangle, an area of muscle weakness between the transverse fibers of the cricopharyngeal muscle and the oblique fibers of the inferior inferior constrictor muscle. The reported prevalence of ZD is between 0.01 and 0.11 percent. The Killian triangle is more frequent in men than in women (60 versus 34 percent). The definitive treatment of symptomatic ZD is surgical. The treatment must be individualized for each case, likewise, the doctor must adopt the one in which he feels most comfortable and as there is more experience in the center in which it is performed, taking into account the technique and the adequate management of complications.
