Abstract

COSTA, Tarciana Vieira  and  DANTAS, Roberto Oliveira. ESOPHAGEAL MOTILITY IN MEN AND WOMEN EVALUATED BY HIGH-RESOLUTION MANOMETRY. Arq. Gastroenterol. [online]. 2017, vol.54, n.2, pp.145-147.  Epub Feb 23, 2017. ISSN 1678-4219.  http://dx.doi.org/10.1590/s0004-2803.201700000-10.

BACKGROUND

Esophageal motility has been described in the literature as having differences between men and women. Most of these investigations use the water perfusion method for esophageal manometry. In this investigation the esophageal motility of men and women was compared with high-resolution manometry of the esophagus.

OBJECTIVE

To compare the esophageal motility of men and women with the high-resolution manometry method for esophageal manometry, performed in the sitting position. The hypothesis was that men and women have differences in esophageal motility.

METHODS

High-resolution manometry was performed in normal volunteers, 10 men [mean age: 37.5 (8.1) years] and 12 women [mean age: 38.7 (7.5) years], in the sitting position and with 10 swallows of a 5 mL bolus of saline, with an interval of at least 30 seconds between consecutive swallows. We evaluated the integrated relaxation pressure of the lower esophageal sphincter, contraction front velocity, distal contraction integral, distal latency, proximal contraction extension, proximal contraction duration >30 mmHg, proximal contraction duration, proximal contraction integral and maximal upper esophageal sphincter pressure.

RESULTS

There was no significant difference between men and women in the variables measured.

CONCLUSION

There was no difference in esophageal motility of men and women evaluated by the high resolution manometry method, in the sitting position with swallows of a liquid bolus.
