摘　　要：目的 应用食管联合阻抗-pH监测技术探讨胃食管反流病中非酸反流的比例及其与烧心的相关程度.方法 选取消化专科门诊以烧心为主诉的连续病例,通过上消化道内镜将上述患者分为糜烂性食管炎（EE）组和非糜烂性反流病（NERD）组,并进一步通过24 h食管多通道腔内阻抗-pH监测及雷贝拉唑试验性治疗予以确诊.比较两组的联合阻抗-pH监测指标.结果 EE组36例,NERD组62例.两组患者酸反流次数、酸反流时间百分比差异有统计学意义（P值分别=0.001和0.002）.EE组和NERD组中非酸反流次数的百分比分别为37.3%（663/1777）和44.3%（1220/2754）,差异有统计学意义（x=21.723,P=0.000）.EE组酸反流烧心症状指数阳性、非酸反流烧心症状指数阳性及总反流烧心症状指数阳性的百分比分别为36.1%（13/36）、19.4%（7/36）和55.6%（20/36）,NERD组则为27.4%（17/62）、6.4%（4/62）和33.8%（21/62）.结论 EE组和NERD组患者中非酸反流次数的比例分别为37.3%及44.3%,非酸反流与烧心关系密切.Objective To investigate the prevalence of non-acidic reflux in patients with gastroesophageal reflux disease and its correlation extent with heartburn symptom by 24-hour combined multichannel intraluminal impedance-pH （MII-pH） monitoring. Methods Consecutive patients with chief complain of heartburn in gastrointestinal specialty clinic were enrolled. Patients were divided into erosive esophagitis （EE） group, non-erosive reflux disease （NERD） group after upper gastrointestinal endoscope, further diagnosed with 24-hour combined MII-pH monitoring and rabeprazole test. The MII-pH parameters were compared in these two groups. Results 36 cases of EE and 62 of NERD were enrolled. There was significant difference in acidic reflux frequency and acidic reflux time percentage between these two groups （P=0. 001 and 0. 002）. The frequency of non-acidic reflux in EE and NERD groups was 37.3% （663/1777） and 44.3% （1220/2754） respectively （x2 =21. 723,P = 0. 000）. The percentage of heartburn symptom positive index in patients with acidic reflux, non-acidic reflux , and total reflux in EE group was 36.1 % （13/36）, 19.4 % （7/36） and 55.6%（20/36） respectively, while in NERD group was 27. 4% （17/62）, 6.4 % （4/62） and 33.8% （21/62）.Conclusion The percentage of non-acidic reflux in EE and NERD groups was 37.3% and 44.3%respectively, and the non-acidic reflux was highly related to heartburn symptom.
