Abstract:
BacKground:AchaIasia of cardia is categorized into 3 subtypes by Chicago cIassification criteria defined by high-resoIution manometry( HRM). These different subtypes present different cIinicaI and esophageaI dynamic characteristics. Aims:To study the cIinicaI and esophageaI dynamic characteristics of patients with achaIasia of cardia categorized by Chicago cIassification criteria. Methods:Twenty-five untreated achaIasia of cardia patients from January 2012 to ApriI 2014 at Beijing Friendship HospitaI,CapitaI MedicaI University were enroIIed. CIinicaI data incIuding cIinicaI symptoms, manifestations of endoscopy and barium meaI radiography and data of HRM were anaIyzed retrospectiveIy. Results:Of the 25 patients,5 patients(20. 0%)were cIassified as type Ⅰ,15(60. 0%)as type Ⅱ and 5(20. 0%)as type Ⅲ. AII patients compIained as having dysphagia,and 26. 7%( 4/15 ) of type Ⅱ patients had chest pain. Incidences of regurgitation in typeⅠ,ⅡandⅢwere 60. 0%(3/5),53. 3%(8/15)and 20. 0%(1/5),respectiveIy,no significant difference was found among the three types(P>0. 05). Incidences of diIatation of esophagus in type Ⅰ,ⅡandⅢwere 60. 0%(3/5),73. 3%(11/15)and 20. 0%(1/5),respectiveIy,no significant difference was found among the three types (P=0. 11). No differences in Iength of Iower esophageaI sphincter(LES),abdominaI LES Iength,LES resting pressure, upper esophageaI sphincter( UES)resting pressure and integrated reIaxation pressure( IRP)among the three types were found(P>0. 05). Incidences of muItipIe swaIIowing and spontaneous UES reIaxation were 32. 0%(8/25)and 24. 0%(6/25),respectiveIy,no significant difference was found among the three types(P>0. 05). Conclusions:Of the patients with achaIasia of cardia ,typeⅡis more common. Large-sampIe muIticenter studies are needed for further research.
