ABSTRACT
Objective To study the features of esophageal motility in the cases with myasthenia gravis(MG).Methods 15 healthy controls and 45 patients with MG were tested by using a low-compliance four-lumen hydraulic infusion system,respectively.Focused on the following parametersPP,UESP,UEP,MEP and MERP.Results There were significant differences of the parameters in between MG cases and healthy controls PP (73.24 ± 31.40) mmHg (1 mmHg =0.133 kPa) vs.(103.78±29.47) mmHg,P=0.002;UESP(41.75 ±21.04) mmHg vs.(60.59 ±17.97) mmHg,P=0.003;UEP (56.63 ±30.26) mmHg vs.(78.98 ±30.14) mmHg,P =0.016;MEP(53.96 ±23.25) mmHg vs.(75.11 ±23.75) mmHg(P =0.004).However,MERP of MG cases or healthy controls seemed to be similar[(-7.76 ± 5.94) mmHg vs.(-7.58 ± 5.76) mmHg,P =0.91).Additionally,the above-mentioned parameters in the cases with generalized myasthenia gravis or dysphagia were significantly different compared with other subtypes or healthy controls (P < 0.01).However,there were no significant differences of the parameters in between ocular MG and healthy controls,or in between MG with and without thymoma.Conclusion The upper and middle part of esophageal motility dysfunction is very common in MG cases,especially in those with dysphagia or generalized MG,characterizing by the declined pressure.Manometry in MG cases can help us classify the subtypes of MG and verify their esophageal motility functions.
