Esophageal Motility in Health and Disease

Recent investigations of esophageal motility in health and disease have been reviewed. Although the methods of investigation have varied widely, there is a striking similarity in the results obtained. The data complement one another and their correlation affords a better understanding of the anatomy and physiology of the esophagus in the normal and diseased state. It is not to be implied that all problems have been solved with finality; on the contrary, many avenues of research are now opening. It is to be expected that further investigations along these lines and, in particular, studies of intraluminal pressures will continue to add to our knowledge.
