Overview
The three different types of the esophageal diverticula are as follows Phrenoesophageal (Zenker's diverticulum-70%), Epiphrenic, Thoracic and mediastinal.
Classification
- Esophageal diverticula are classified on the basis of location into three types[1][2][3]
- Almost all esophageal diverticula are acquired pulsion diverticula.
1. Phrenoesophageal (Zenker's diverticulum-70%)
- ZD is a defect over the Killian's triangle, a point of weakness in the muscular wall of the hypopharynx
2. Epiphrenic (20%)
- Epinephric diverticula result either from hypertonia of the lower esophageal sphincter (esophageal achalasia)
3. Thoracic and mediastinal (10%)
- Thoracic diverticula are probably more often of a congenital than traction origin.
