摘要 目的探讨24h食管多通道腔内阻抗-pH(MII-pH)监测在胃食管反流性疾病(GERD)中的应用及其临床意义。方法选取2011年7月至2012年6月因反流症状就诊于我院消化科的GERD患者53例,根据内镜特征表现将患者分为糜烂性食管炎组25例、非糜烂性反流病组28例;纳入同期健康志愿者15名为正常对照组。比较各组之间行单纯食管24h的pH监测以及24h的MII—pH监测指标的变化及其意义。结果单纯食管24h的pH监测结果提示糜烂性食管炎组、非糜烂性反流病组患者各项酸反流指标均高于正常对照组(P均〈0.05)。24h的MII—pH监测提示糜烂性食管炎组、非糜烂性反流病组患者总反流[83(54,118)次、62(44,111)次]、酸反流[45(25,79)次、22(11,45)次]、弱酸反流[36(18,47)次、43(21,82)次]及酸反流所占百分比[53%(37%,81%)、32%(13%,48%)]较正常对照组[42(20,70)次、3(1,10)次、23(11,43)次、11%(1%,23%)]明显增加,两组比较差异有统计学意义(P值分别为0.003、0.000、0.001和0.002);同时糜烂性食管炎组较非糜烂性反流病组的酸反流明显增加(P=0.000)。非糜烂性反流病组中弱酸反流所占百分比[66%(43%,79%)]较糜烂性食管炎组[46%(21%,57%)高,P〈0.01];糜烂性食管炎组、非糜烂性反流病组患者的液体反流次数[22(12,40)次、18(12,26)次]及混合反流[54(39,79)次、42(25,77)次]较正常对照组[9(4,18)次、29(14,48)次]明显增加(P均〈0.01);正常对照组的气体反流次数[86(56,207)次]较糜烂性食管炎组[31(14,62)次]、非糜烂性反流病组[34(15,119)次]明显增多(P均〈0.01);糜烂性食管炎组、非糜烂性反流病组近端反流次数[28(18,41)次、16(12,34)次]及所占比例[33%(22%,49%)、29%(22%,35%)]较正常对照组[3(2,9)次、11%(6%,22%)]明显增高(P均〈0.01);糜烂性食管炎组酸反流、弱酸反流及总反流症状指数阳性率分别为36.0%(9/25)、20.0%(5/25)及56.0%(14/25),非糜烂性反流病组为21.4%(6/28)、14.3%(4/28)和35.7%(10/28),较单纯酸反流症状指数百分比升高。结论24h的MII—pH监测能发现更多反流事件,酸反流在GERD中占主要地位;24h的MII—pH监测增加了GERD的检出率,具有重要的临床应用价值。 Objective To investigate the application and clinical significance of 24-hour muhichannel intraluminal impedance-pH (MII-pH) monitoring in gastroesophageal reflux disease (GERD). Methods Fiftythree patients with GERD were enrolled in this study according to the Montreal consensus ( consulting for twice reflux a week or above) from July 2011 to June 2012. Patients were divided into erosive esophagitis (EE, n = 25 ) group and non-erosive reflux disease ( NERD, n = 28 ) group after endoscopy and MII-pH monitoring. Fifteen healthy volunteers were recruited as the normal controls. The change of pH and MII-pH parameters were compared among the three groups and the significance of the change was investigated. Results Twenty-four-hour pH monitoring showed that all the acid reflux events in the EE and the NERD groups were significantly higher than those in the control group ( P 〈 0. 05 ). MII-pH monitoring showed that the frequencies of total reflux, acid reflux,weakly acidic reflux and percentage of acid reflux in the GERD group were higher than in the control group ( total reflux : 83 ( 54, 118 ) vs. 62 ( 44, 111 ) vs. 42 ( 20,70), P = 0. 003 ; acid reflux : 45 ( 25,79 ) vs. 22 ( 11,45 ) vs. 3 ( 1,10 ), P = 0. 000 ; weakly acidic reflux : 36 ( 18,47 ) vs. 43 ( 21,82 ) vs. 23 ( 11,43 ), P = 0. 001 ; percentage of acid reflux:53% (37%, 81% ) vs. 32% ( 13% ,48% ) vs. 11% ( 1% ,23% ), P = 0. 002 ). The frequency and percentage of acid reflux in the EE group were higher than those in the NERD group (P =0. 000) The percentage of weakly acidic reflux in the NERD group was higher than in the EE group (66% (43%, 79% ) vs. 46% (21% ,57% ) ,P 〈0. 01 ). The frequencies of liquid reflux and mixed reflux in the GERD groups were higher than those in the control group ( 22 (12,40) vs. 18 ( 12,26 ) vs. 9 ( 4,18 ) ; 54 ( 39,79 ) vs. 42 ( 25, 77) vs. 29(14,48) ;P 〈0. 01 ). The frequency of gas reflux in the control group was higher than in the GERD group ( 86 (56,207) vs. 31 ( 14,62 ) vs. 34 ( 15,119 ) , P 〈 0. 01 ). The frequency and percentage of proximal reflux in the GERD group were significantly higher than in the control group (28( 18,41 ) vs. 16(12,34) vs. 3 (2,9);33% (22%,49%) vs. 29% (22%,35%) vs. ll% (6%,22%),P 〈0.001).The percentage of symptom positive index in patients with acid reflux, non-acidic reflux and total reflux in the EE group were 36. 0% (9/25) ,20.0% (5/25) and 56. 0% (14/25) respectively which were higher than in the NERD group (21.4% (6/28),14.3% (4/28) and 35.7% (10/28)). Conclusion MII-pH monitoring can detect more reflux events. Acid reflux plays an important role in GERD. The detective rate of GERD will be elevated when combined with MII-pH monitoring in the diagnosis. MII-pH monitoring has a distinct advantage in diagnosing GERD.
