Fig. 1. A representative image of the measure of esophageal length was done from the upper sphincter’s inferior border and the lower sphincter’s superior (lower esophageal sphincter [LES]) border, with the isobaric contour set at 30 mmHg. Delta value from baseline to post-swallow was considered esophageal shortening. (A) LES concords with the diaphragmatic impression (red broken rectangle). (B) LES (red broken rectangle) and separated 2.3 cm from a diaphragmatic impression (blue pointed rectangle, hiatal hernia).
