The value of simple tests for peristaltic activity in hiatus hernia
Abstract
A study has been made of oesophageal peristaltic activity as viewed at barium swallows, in an effort to see whether this is helpful in assessing the type and degree of oesophageal lesions associated with hiatus hernia. It has not been possible to establish a clinical usefulness from such testing as the frequency with which peristaltic upset occurs is too marginal.
