ABSTRACT
BACKGROUND/AIMS:
It is suggested that diffuse esophageal spasm (DES), nutcracker esophagus (NUT), and hypertensive lower esophageal sphincter (HLES) could be re-classified together as a spastic esophageal motility disorder of similar clinical backgrounds. However, there were no studies to evaluate the pathophysiological characteristics of these motor abnormalities. The aim of the study was to evaluate the changes of esophageal motor function depending on the different types of the bolus (water vs semi-solid bolus).METHODS:
Twenty-one healthy subjects and 42 subjects with primary esophageal motility disorders (4 DES, 12 NUT, 5 HLES, 12 nonspecific esophageal motility disorders, 9 normal) underwent a perfusion manometry with a low compliance pneumo-hydraulic capillary infusion system. Consecutively, each patient had 10 swallows of water and 10 swallows of Jello, 5 ml each.RESULTS:
In the healthy controls, the Jello swallow showed an increased amplitude and duration of distal esophageal contractions, and the velocity of peristalsis was decreased (p < 0.05). Among all patients diagnosed by manometry with the water swallow, 2 cases diagnosed with HLES (40%) and 4 with NUT (33%) were changed to a diagnoses of DES after the Jello swallow. Moreover, HLES was found in 1 patient with DES (25%) and in 6 patients with NUT (50%).CONCLUSIONS:
Semi-solid bolus swallows increase the contractile force of the esophagus more than water swallows. A conventional manometric diagnosis could be changed to a different spastic motility disorder of the esophagus after a semi-solid bolus swallow. It is suggested that DES, NUT, and HLES can be considered as a spectrum of spastic esophageal motility disorders sharing a similar pathophysiology.
