Objectives : The aim of this study was to investigate the characteristics of Ryodoraku and association of Ryodoraku with gastric dysmotility in functional dyspepsia(FD).
Methods : Subjects were 154 patients with FD and 18 patients with asthma. We calculated the average Ryodoraku score(RS, ) and each variation from physiologic range of 12 Ryodoraku points, and investigated the incidence when left and right points were simultaneously below(bilateral deficiency) or above(bilateral excess) physiologic range. Postprandial regularity of normal slow waves, power ratio, and postprandial % of bowel sound were obtained by electrogastrography and enterotachography, and were used as gastric dysmotility index.
Results : 1. Bilateral excess of H4, H5, F1, and F4 and bilateral deficiency of H4, H5, and H6 were characteristic in FD compared with asthma patients. 2. Incidence of gastric dysmotility in bilateral deficiency of H4, H5, and H6 was 100%, and was higher than in total FD patients(88.3%). 3. There was a positive correlation between the variation of H6 and % postprandial bowel sound. 4. Deficient tendency of H4, H5, and H6 was more evident when RS was above in FD.
Conclusions : These findings suggest that gastric dysmotility in FD can be diagnosed when a pattern of H4, H5, H6 bilateral deficiency and F1, F4 bilateral excess is shown at the same time. We think this phenomenon is related to low activity of the vagus nerve rather than meridian pathway with result based on positive correlation between variation of H6 and postprandial % of bowel sound.
