Abstract:
Objective To investigate the dynamic changes in achalasia patients by using high resolution manometry (HRM).Methods Twenty-four achalasia patients were enrolled for HRM examination and typing.The esophageal pressure of patients with different subtypes was analyzed.Chi-square test was used for count data analysis.Two independent samples t-test was used for measurement data.Results Among twenty-four achalasia patients,five patients were type Ⅰ and maledominated,18 patients were type Ⅱ and female was more than male,and only one male patient was type Ⅲ.The frequency of weight loss in type Ⅰ was higher than that of type Ⅱ (x2 =6.97,P=0.008).The frequency of chest pain and food reflux in type Ⅰ was higher than that of type Ⅱ (both P＞0.05).The average distance from the nares to the upper edge of the lower esophageal sphincter (LES) with the electrode successfully inserted into the stomach was (44.9±3.3) cm and to the lower edge of the LES was (48.0±3.2) cm.The average LES length was (3.1 ±0.7) cm,average intraabdominal LES length was (2.1 ±0.5) cm.The average LES resting pressure was (34.6 ± 13.8) mm Hg (1 mm Hg =0.133 kPa) and the integrated relaxation pressure (IRP) was (31.1 ± 12.0) mm Hg.Conclusion Esophageal manometry is the golden standard for achalasia diagnosis,and HRM may be a simple,direct viewing and accurate method for accessing esophageal motor function.
