Answer

Answer

Zenker diverticula occur more commonly in certain parts of the world. They are observed most often in northern European countries and in countries whose population has a northern European heritage (eg, United States, Canada, Australia). Zenker diverticulum is rarely observed in Japan and Indonesia. The prevalence in high-risk countries is 2 cases per 100,000 people. It has a male-to-female ratio of 1.5:1 and is observed almost exclusively in older individuals.
