SUBSTANCE: the present innovation deals with predicting esophageal motor function both in school-children and grown-ups. It is necessary to register esophageal sections at impedance values being below threshold value of observed gastroesophageal reflux (GER) and values for motor function. At decreased impedance in any area against threshold value considered as 100% one should diagnose decreased esophageal tonicity, at impedance values ranged 100-200% - normal tonicity, above 200% - increased tonicity. Graph should be plotted which X-axis depicts the time for survey, Y-axis - the distance against the level of the lower esophageal sphincter. One should plot characteristics of tonicity in every area per time unit by combining into hypo-, normo-, hypertonic areas and depicting them with different colors. In hypertonic sections it is necessary to detect the value for esophageal barrier function (BF) by 4-point system, moreover, the first digit after BF depicts the duration of hypertonic esophageal contractions and corresponds to 3 points at hypertension duration being 90% of survey time, not less, 2 points - at duration being 40-90%, 1 point - at duration being 40%, not higher, 0 points - no. The second digit is quantitative evaluation in prevalence of hypertensive contractions and corresponds to 3 points at distribution of hypertensive areas by more than 7 cm, 2 points - by 4-7 cm, 1 point - not more than 4 cm, 0 points - no. At BF23, BF32, BF33 one should diagnose severe form of hypertonic esophageal dyskinesia, BF13, BF22, BF31 - average severe form, BF11, BF12, BF21 - light form. In hypotonic sections one should determine the value of isolated refluxate residues (RR) and the value of reflux type (RT) by 4-point system to characterize hypertension degree in distal esophageal departments. The first digit after RR depicts retention time for refluxate evacuation and corresponds to 3 points at duration of hypotonic sections of 25% of survey period, not less, 2 points - 10-25%, 1 point - 10%, not more, 0 points - no. The second digit is being quantitative value for the quantity of refluxate residues in hypotonic esophageal sections and corresponds to 3 points at sections of more than 6 cm, 2 points - 3-6 cm, 1 point - not more that 3 cm, 0 points - no. At RR23, RR32, RR33 one should diagnose severe form of hypotonic esophageal dyskinesia, RR13, RR22, RR31 - average severe, RR11, RR12, RR21 - light form. The first digit after RT depicts GER duration and corresponds to 3 points at hypotonicity duration of not less than 90% of survey time, 2 points - 40-90%, 1 point - not more than 40%, 0 points - no. The second digit after RT is quantitative evaluation of GER height and corresponds to 3 points at the height of hypotonic sections of above 11 cm, 2 points - 6.5-11 cm, 1 point - below 6.5 cm, 0 points - no. At RT23, RT32, RT33 one should diagnose cardiac insufficiency of severe degree, RT13, RT22, RT31 - average degree, RT11, RT12, RT21 - light degree. The method enables to detect the severity degree of esophageal hypo- and hypertonicity, quantitative evaluation of strength, prevalence and duration of tonic contractions and interactions of different esophageal departments.
EFFECT: higher accuracy of diagnostics.
