An esophageal diverticulum is a pouch, or pocket, of stretched tissue that develops anywhere along the esophagus, pushing outward through its muscular wall. They are rare, and can be congenital or acquired. Typically a single pouch forms, most often near the top of the esophagus; this is called Zenkerâs diverticulum. In other cases, a pouch forms nearer to the bottom of the esophagus (epiphrenic) or, less frequently, in the middle. A single diverticulum ranges from 1 to 4 inches in diameter.
