Abstract
The clinically important diverticula of the thoracic esophagus occur in the epiphrenic region. The vast majority are pulsion diverticula secondary to herniation of the mucosa through the muscularis propria. Large diverticula may be symptomatic and are associated with hiatal hernia or neuromuscular dysfunction of the esophagus. Small diverticula are asymptomatic except when associated esophageal disease is present. Careful evaluation of the esophagus for the presence of associated disease is essential. Surgery should be directed towards the associated disease as well as the removal of the diverticulum.
