Clinical Trial Summary

High resolution esophageal manometry normative values are still need to be studied in different populations and with the use of solid-state and water-perfused systems. There has been no study on the subject in healthy Russian population yet.


Description:

High-resolution esophageal manometry (HREM) is the current modality used to evaluate esophageal motility. There are 2 types of system: water-perfused system that is cheaper to maintain and a solid-state system that is considered to be more sensitive. According to the data obtained in the study of 400 patients and 75 controls by J Pandolfino et al it was proposed to use a common algorithm of HREM data interpretation and the normative values of the parameters used to interpret the color plots of HREM. This formed the basis for the first version of the currently used HREM reporting algorithm and classification of esophageal motility disorders called Chicago Classification (CC). To date, this classification has been updated several times by the International Working Group based on the recently published data. The Working group stated that the proposed normative values still need to be widely studied for each HREM system and in different populations. Some studies has been published recently on the normative values of HREM in different countries (predominantly in the US, in some European countries, Korea, India and China. But there has been no study on the subject in Russia still.

The duration of the period of non-use of these drugs should provide sufficient time for the complete cessation of their pharmacological action, but not less than two half-life. - pregnant or breastfeeding women - any condition making impossible to perform high resolution esophageal manometry (previously known poor tolerability of the procedure; narrow nasal passages; significant curvature of the nasal septum etc).

Primary Mean DCI distal contractile integral - Amplitude x duration x length (mmHg x s x cm) of the distal esophageal contraction exceeding 20 mmHg from the transition zone to the proximal margin of the LES mean value of 10 swallows by 30 seconds (about 7 minutes per subject)
Primary Mean DL distal latency - Interval between UES relaxation and the contractile deceleration point mean value of 10 swallows by 30 seconds (about 7 minutes per subject)
Primary Mean upper esophageal sphincter mean resting pressure mean pressure of the upper esophageal sphincter mean value based on 30 seconds measurement of a subject
Primary Mean lower esophageal sphincter mean resting pressure mean pressure of the upper esophageal sphincter mean value based on 30 seconds measurement of a subject
