目的 研究贲门失弛缓症患者的食管压力变化。方法 对 35例贲门失弛缓症患者与 30位正常对照的食管测压数据进行对比分析。结果 贲门失弛缓症组食管体部均为同步蠕动波 ,91 4 % (32 / 35 )为低幅同步收缩波 ;食管下括约肌松弛率 (LESRR)为 (6 9 1± 16 3) % ,明显低于正常对照的 (96 0± 0 1) % (P <0 0 1) ;食管下括约肌压增加 ;食管上括约肌各项指标与正常对照组比较无明显差别。结论 贲门失弛缓症的食管压力以低幅同步收缩波和LESRR增高为特征性表现。
Objective To study esophageal pressure changes in patients with achalasia. Methods 35 cases of achalasia patients and 30 normal control esophageal manometry data for comparative analysis. Results The esophageal body of patients with achalasia were all synchronous peristalsis, 91 4% (32/35) were low amplitude systolic wave, and the lower esophageal sphincter relaxation rate (LESRR) was (6 9 1 ± 16 3)% Lower than normal control (96 0 ± 0 1)% (P 0 01). The lower esophageal sphincter pressure increased. There was no significant difference between the upper esophageal sphincter and the normal control group. Conclusions Esophageal pressure in achalasia is characterized by low amplitude systolic wave and increased LESRR.
