Bennett B, Akhondi H. Epiphrenic Diverticula. StatPearls 2020; .
Epiphrenic diverticulum, also known as a pulsion diverticulum, is a rare type of esophageal diverticulum occurring in the distal 10 centimeters (CM) of the esophagus, most commonly 4cm to 8 cm above the gastric cardia. These diverticula are made up of the mucosal and submucosal lining, herniating through a weakness in the muscularis layer of the esophagus, classifying them as false or pseudodiverticula. This anatomical weakness in the muscularis layer is where nerves and blood vessels enter to supply the distal esophagus.
