    Abstract:
    OBJECTIVE: Data are limited on the effect of age on esophageal function. We evaluated whether aging influences the motor activity of the esophagus. METHODS: Standard esophageal manometry was performed in 79 healthy, nonpaid volunteers of both sexes, 18-73 yr of age. Lower (LES) and upper esophageal sphincter (UES) characteristics and the properties of esophageal peristaltic waves were assessed by age groups: < or = 25 yr, 26-35 yr, 36-45 yr, 46-55 yr, 56-65 yr, and > 65 yr. RESULTS: Age correlated inversely with LES pressure and length, UES pressure and length, and peristaltic wave amplitude and velocity, and correlated directly with the proportion of simultaneous contractions. Age was inversely correlated with the upper limits of normality (95th percentiles) of LES pressure (r = -0.943, p = 0.005), UES pressure (r = -0.943, p = 0.005), middle and lower peristaltic wave amplitude (r = -0.947, p = 0.004, and r = -0.844, p = 0.035, respectively), upper/middle peristaltic progression speed (r = -0.943, p = 0.005), and the proportion of simultaneous contractions (r = 0.926, p = 0.008), but not with the lower normal limits (5th percentiles) of these variables. Gender did not affect esophageal motility variables. The 95th percentiles of LES pressure differed by 20 mm Hg, those of lower peristaltic amplitude by 82 mm Hg, and those of percent simultaneous contractions by a factor of 2, between the younger and the older age groups. CONCLUSIONS: The results suggest that normal esophageal motility deteriorates with advancing age. Thus, age-related normality limits of esophageal pressures should be considered before establishing the manometric diagnosis of hypercontractile esophageal motility disorders.
