[[Surgery]] is the most definitive therapy for the [[Zenker's diverticulum]] (ZD). If small and [[asymptomatic]], no [[Treatment IND|treatment]] is necessary. Larger, [[symptomatic]] cases of [[Zenker's diverticulum]] have been traditionally treated by [[neck]] surgery to [[Resection|resect]] the [[diverticulum]] and [[incise]] the [[cricopharyngeus muscle]]. However, in recent times non-surgical [[endoscopic]] techniques have gained more importance, and the currently preferred [[Treatment IND|treatment]] is [[endoscopic]] stapling i.e. closing of the [[diverticulum]] via a stapler inserted through a tube in the [[oral cavity]]. This may be performed through a [[Fiberoptic intubation|fiberoptic endoscope]]. Other non-surgical [[Treatment IND|treatment]] [[Modality|modalities]] exist, such as [[endoscopic]] [[laser]], but recent [[evidence]] has shown it to be less effective than stapling.

Overview

Surgery is the most definitive therapy for the Zenker's diverticulum (ZD). If small and asymptomatic, no treatment is necessary. Larger, symptomatic cases of Zenker's diverticulum have been traditionally treated by neck surgery to resect the diverticulum and incise the cricopharyngeus muscle. However, in recent times non-surgical endoscopic techniques have gained more importance, and the currently preferred treatment is endoscopic stapling i.e. closing of the diverticulum via a stapler inserted through a tube in the oral cavity. This may be performed through a fiberoptic endoscope. Other non-surgical treatment modalities exist, such as endoscopic laser, but recent evidence has shown it to be less effective than stapling.

Surgery

Rigid endoscopic diverticulotomy

Four types of procedures are performed using rigid scope

1.Endoscopic electrocautery

Endoscopic electrocautery may be used as a treatment option for Zenker's diverticulum:[5][6]

Complications:

2.Endoscopic CO2 laser technique

Endoscopic CO2 laser technique may also be used as a treatment option for Zenker's diverticulum:[7][8]

  • This technique offers high energy and high focused beam.
  • Very minimal tissue trauma.
  • It also provides a better visualization of the diverticular bridge and easier control of the operation.

Complications:

3.Endoscopic stapling

Endoscopic stapling is one the preferred treatment options for Zenker's diverticulum:[9]

4.Endoscopic harmonic scalpel

Flexible Endoscopic Diverticulotomy

Complications of the Endoscopic procedures[10]
