Zenker Diverticulum or Pharyngoesophageal Diverticulum 

It is a outpouching of the mucosa of the posterior pharyngeal wall through Killian's triangle(also known as Laimer's triangle, and the Killian-Laimer triangle)an area of weakness between the two parts of the inferior pharyngeal constrictor - the thyropharyngeus and the cricopharyngeus - at their posterior margin.Zenker diverticulum has male predominence and is observed almost exclusively in older individuals.

  • Uncoordinated swallowing
  • Impaired relaxation and spasm of the cricopharyngeus muscle

Zenker diverticula extend into the left neck 90% of the time


  • Dysphagia
  • Palpable swelling in the neck in two-thirds of cases
  • Involuntary gurgling noises when swallowing
  • Halitosis
  • Regurgitation of undigested food hours after eating
  • Sensation of food sticking in the throat
  • Coughing after eating
  • Aspiration of organic material
  • Episodes of pulmonary infection
  • Unexplained weight loss

  • Aspiration
  • Bleeding from the mucosa
  • Esophageal obstruction
  • Tracheal Fistulation
  • Squamous cell carcinoma - but very rare


Barium swallow with videofluoroscopy


If small and asymptomatic, no treatment is necessary
In symptomatic cases
Excision of the pouch combined with myotomy (longitudinal division - of the cricopharyngeus)
Approaches at the level of the cricoid cartilage or obliquely through the left sternomastoid have been used to excise the pouch
Risks of surgery such as fistula formation, mediastinitis, inhalation pneumonia and recurrent laryngeal nerve damage
Endoscopic stapling performed through a fibreoptic endoscope

    zenker diverticula
    The precise cause of ZD remains unsettled but it occurs in a variety of circumstances predisposing to herniation within Killian's triangle, such as abnormal esophageal motility, esophageal shortening, or disorders associated with UES dysfunction.

    Treatment of patients with Zenker's diverticula should consider the availability of local expertise. Experience is important, regardless of which method is used

    We suggest rigid or flexible endoscopic treatment be considered in centers with a trained endoscopist who has demonstrated favorable outcomes (Grade 2C). Exceptions are young patients with large diverticula
