Background: High-resolution manometry is more costly but clinically superior to conventional manometry. Water-perfused systems may decrease costs, but it is unclear if they are as reliable as solid-state systems, and reference values are interchangeable. Aim: To validate normal values for a new water-perfusion high-resolution manometry system. Methods: Normative values for a 24-sensors water perfused high-resolution manometry system were validated by studying 225 individuals who underwent high resolution manometry for clinical complaints. Patients were divided in four groups: group 1 - gastroesophageal reflux disease; group 2 - achalasia; group 3 - systemic diseases with possible esophageal manifestation; and group 4 - dysphagia. Results: In group 1, a hypotonic lower esophageal sphincter was found in 49% of individuals with positive 24 h pH monitoring, and in 28% in pH-negative individuals. In groups 2 and 3, aperistalsis was found in all individuals. In group 4, only one patient (14%) had normal high-resolution manometry. Conclusions: The normal values determined for this low-cost water-perfused HRM system with unique peristaltic pump and helicoidal sensor distribution are discriminatory of most abnormalities of esophageal motility seen in clinical practice.

“…In the journal Arquivos de Gastroenterologia, two articles were published simultaneously, emanating from one institution and devoted to high resolution manometry (HRM) of the esophagus and the lower esophageal sphincter (1,2) . The first study aims to determinate the normative data for a new 24 channel water-perfused HRM (1) . In this study the basic methodological principles have been violated.…”

“…The management of gastroesophageal reflux disease and other esophageal motility disorders is highly dependent on these tests. We thank Dr. Levin for his interest in two of our studies (1,2) . We were thrilled with his disapproval of current methods to evaluate esophageal physiology.…”
