Introduction: The baseline period after adaptation of the patient is relatively little described about its technique, mentioning that “this capture must have a minimum duration 30 seconds to enable identification anatomical landmarks and pressure profile at rest. Being unfamiliar with sensation nasopharyngeal foreign body, provides limited cooperation, this predisposes more inaccurate measurements beginning high-resolution manometry study. By adapting better following indications cooperating dynamics study, variations are found in metric portions evaluated. In project, we reviewed contrasts different gastrointestinal motility laboratories Mexico City, normative values profiles rest from initial versus end HRM study 2018-2021. Methods: Review MAR studies electronically archived ManoScan ESO SANDHILL SCIENTIFIC Insight G3 Manometry systems, belonging participating protocol, help ManoView Sandhill Zvu analysis software 2.1. normality groups was corroborated by Kolmogorov-Smirnov test. statistical test used student’s t for paired samples. data presented as mean (standard deviation). A p < .05 95% Confidence Interval will be taken significance. carried out package SPSS v.21.0® Results: 25 patients January 2018 May 2021 were analyzed, an average age 52 (SD 16) years, which 18 men (65%), results our listed Table 1. Conclusion: Statistically significant differences 4 parameters, mostly reference when evaluating window decrease EES stands out, perhaps secondary presence catheter. We consider expanding sample recommend whether tone considered evaluation upper esophageal sphincter.Table 1.: Anatomical final periods.
