Pulsion diverticula tend to be located in the distal esophagus and are often associated with fluoroscopic or manometric evidence of esophageal dysmotility. The diverticula are usually detected as incidental findings in patients who have no esophageal symptoms. However, a large epiphrenic diverticulum adjacent to the GEJ may fill with debris, causing dysphagia, regurgitation, or aspiration (Figure 6.71). Pulsion diverticula appear on barium studies as rounded outpouchings from the esophageal lumen that have wide necks. They often do not empty completely when the esophagus collapses and may be associated with other radiologic findings of esophageal motor dysfunction.
