RÉSUMÉ
Objective To evaluate the clinical and manometric characteristics of achalasia.Meth-ods Patients diagnosed as having achalasia from July 2010 to July 2014 at our hospital were enrolled.High resolution manometry(HRM)results were analyzed.Data of Eckardt scale,MDADI and SF-36 were ana-lyzed.Results All subjects had dysphagia,35.6% (37 /104)accompanied with regurgitation,26.9%(28 /104)with heartburn and 17.3%(18 /104)with weight loss.According to HRM results and Chicago classification criteria,16.35%(17 /104)of the subjects were classified as type Ⅰ,76.92%(80 /104)as type Ⅱ and 6.73%(7 /104)as type Ⅲ.27.9%(29 /104),19.2%(20 /104)and 24.0%(25 /104)of the subjects finished Eckardt scale,MDADI and SF-36,respectively.Eckardt score was positively correlated with integrated relaxation pressure(IRP)(r =0.421,P <0.05)and MDADI physical score was negatively with IRP(r =-0.530,P <0.05).Conclusion Dysphagia often occurs as the chief complaint among acha-lasia patients.And type Ⅱ is the most common.IRP is an indicator of the severity of clinical symptoms and impairment of quality of life.
