Flexible endoscopic evaluation of swallowing (FEES) provides information that may suggest the presence of a Zenker diverticulum, but this test has not supplanted the barium swallow in most surgeons' practices. Pooling in the esophageal introitus may be ascertained in individuals with a Zenker diverticulum by using cream or other readily visible forms of food of various consistencies. This test may help to select patients for whom barium swallow is appropriate.
