Joe Y1 - 2019 N1 - T2 - Maingot's Abdominal Operations, 13e AB - Diverticula of the esophagus are a rare entity, with a prevalence that ranges between 0.06% and 4%.1,2 Esophageal diverticula are classified according to their location along the esophagus (pharyngoesophageal, midesophageal, or epiphrenic), and the mechanism of formation (pulsion or traction). Most common diverticula are those located in the pharyngoesophageal and epiphrenic locations. These are usually pulsion diverticula in which an increase of intraluminal pressure leads to herniation of mucosa and submucosa through the muscular layer resulting in a false diverticulum. Mid-esophageal diverticula are commonly traction diverticula. These are much less frequent and are the result of a focal traction of all layers (mucosa, submucosa, and musculature) of the esophageal wall by a periesophageal inflammatory process resulting in a true diverticulum.
