Treatment of Zenker's diverticulum has been exclusively through open neck surgery. However, patients with this problem are generally elderly, so the surgical risk increases.

In recent years, endoscopic techniques have been developed in order to solve this  problem. Endoscopy uses the mouth as an access route, which is why the complications inherent to surgery, recovery times and the cost of the procedure have been reduced.

Taking these factors into account, the endoscopic approach to Zenker's diverticulum has become the treatment of choice, displacing surgery in the background.
