To Study The Pressure Of Balloon Dilatation And Evaluate The Curative Effect For Cardia Achalasia

[Objective] Evaluate the curative effect of pneumatic balloon dilatation in patients with achalasia. And study if the lower esophageal sphincter pressure (LESP) as the selected norm of dilation's pressure.[Methods] 47patients took part in this study. 17 cases in control group,30 cases in study group. According to the LESP before dilation, the study group were separated into two small groups again. One group LESP>20mmHg, 21 cases, another LESP≤20mmHg,9 cases. All patients were done the dilatation under gastroscope, and followed up for six months, asked for their clinical symptomes. Before and after dilation, both within 3 days, all patients were done the esophagus manometry, analyse the LESP and lower esophagus sphincter relaxation rate ( LESR ) among the groups.[Results] In the operation, all patients felt stethalgia and exist cardiac mucous membrances avulsion . 4 cases had animal heat hoist after operation. All of them straightan up by themselves. Only one patient exist perforation whith belong to LESP>20mmHg group. 4 patients recrudesce in control group, 5 cases in LESP> 20mmHg group and 1 cases in LESP≤20mmHg group. All patients the clinical symptom was obviously releaved. Analysising the symptom score and LESP, LESR of the two small group, we elicit that pneumatic balloon dilation has good curative effect in near future and has not obviously difference between the groups. [Conclusions] Pneumatic balloon dilatation to treatment cardia achalasia has good curative effect in near future .The LESP before dilation would be the selected norm of dilatation's pressure.
