High resolution manometry in patients with esophageal motor disorders
Abstract
Introduction: High-resolution manometry is the gold standard for the study of esophageal motor disorders. Objective: A descriptive, cross-sectional research was carried out in el Centro Nacional de Cirugía de Mínimo Acceso, between September 2018 and December 2019, in 56 patients, diagnosed with esophageal motor disorder by high-resolution manometry, aged between 18 and 20 years, who gave their consent to participate in the study. Esophageal achalasia and minor peristalsis disorders were excluded. The variables included were: age, sex, manometric diagnoses and their characteristics, symptoms, types of esophagogastric junction, imaging or endoscopic diagnoses. For the analysis of the results, the percentage, measures of central tendency and Pearson's chi square of homogeneity were used, with a level of statistical significance p ≤ 0.05 and 95 % reliability. Development: Absent contractility (39,28 %), female sex (58,9 %) and dysphagia (66,07 %) predominated. The obstruction to the flow of the esophagogastric junction corresponded to the highest mean resting pressure of the lower esophageal sphincter (43,28 mmHg) and the mean integrated pressure ratio above 15 mmHg (38,88 mmHg). The hypercontractil esophagus presented mean high integrated distal contractility (5564,25 mmHg/s/cm). Rapid contractions were found in distal esophageal spasm (mean 21,4 cm/s). Conclusions: High resolution manometry was feasible to be used for the diagnosis of major esophageal motor disorders.
