24小时食管pH及动力学监测在新生儿胃食管返流诊断中价值

为了解24h食管pH值监测在新生儿胃食管返流(GER)诊断中的作用和新生儿胃食管返流的临床特点及与之相关的疾病，采用便携式pH自动记录仪监测：106例临床上怀疑有胃食管返流的新生儿(症状组)，其中55例同时用台式高分辨八道胃肠动力监测系统行食管动力学监测；同时监测17例无症状新生儿(对照组)，动力学测定5例。结果显示，新生儿胃食管返流临床表现多样。以呕吐(溢乳)多见(97．6％)，其次为呼吸暂停(发绀，占14．5％)，呛咳(9．6％)；除了单纯病理性GER及继发于消化道畸形外，新生儿缺氧缺血性脑病及败血症与GER关系密切，而继发有消化道器质性疾病时，返流更严重。病理性GER食管动力异常的检出与对照组相比差异无显著性。提示新生儿胃食管返流临床表现复杂，可由多种疾病引起，及早行24h食管pH值测定是早期诊断新生儿GER的客观依据，但同时应警惕有基础疾病的可能，及时作相应的检查以增加诊断的正确性；此外尚需进一步制定与年龄相关的食管动力标准。     

24 h食管pH监测诊断儿童胃食管返流病临床意义

目的 总结胃食管返流病患儿行24h食管pH监测的回溯性检查结果，分析其在临床上的应用意义。方法 对收治的150例无消化道梗阻患儿进行24h食管pH监测，男64例，女86例；年龄最小1个月，最大7岁，平均年龄3．45岁。按吞钡检查结果和临床表现将患儿分为4组：A组18例，为不明原因呕吐、内科保守治疗无效者，B组80例拟诊为胃食管返流病，C组47例为食管裂孔疝患儿，D组5例，表现为夜间有突然呛咳、胸痛。其中A组和D组食管吞钡检查均无异常。结果 A组患儿存在明显的胃食管返流；B组有65例存在胃食管返流，15例不符合胃食管返流病的诊断标准，检查结果与食管吞钡不一致；C组41例滑疝患儿存在胃食管返流，而6例食管旁疝无返流；D组患儿有胃食管返流病，以睡眠期返流为主，且返流的出现与其症状发生相一致。结论 通过24h食管pH检查可明确症状与返流的关系、返流程度及返流与体位、进食、疼痛的关系；24h食管pH监测特异性、敏感性较高，对检查者无损伤，因此在临床应用中，应与食管吞钡检查相互结合、相互补充，有利于提高诊断的正确性。     

动态24小时食管pH值监测小儿胃食管返流

为了解２４小时食管ｐＨ值监测在小儿胃食管返流（ＧＥＲ）诊治中的作用，研究小儿病理性ＧＥＲ的特点及其诊断标准，对５０例经钡餐造影诊为ＧＥＲ的患儿进行动态２４小时食管内ｐＨ值监测，３０例健康小儿为对照组，复查１３例病理性ＧＥＲ患儿治疗后（９例为手术治疗）的食管ｐＨ值。结果表明，ＧＥＲ组各项返流指标显著高于对照组。对照组中１例为病理性ＧＥＲ，ＧＥＲ组３１例为病理性，另１９例则为生理性。１３例食管裂孔疝（ＨＨ）患儿均有明显的病理性返流，其各项返流指标除ｐＨ值＜４次数外均显著高于单纯病理性ＧＥＲ；ＨＨ组卧位时返流≥５分钟次数、最长返流时间、总ｐＨ值＜４的时间占总观察时间的百分比和平均返流周期均显著大于立位时；单纯病理性ＧＥＲ组卧位时返流≥５分钟次数、最长返流时间和平均返流周期显著大于立位时，而返流次数则小于立位时。提示小儿病理性ＧＥＲ以卧位时明显，伴有食管裂孔疝者返流更为严重。动态２４小时食管内ｐＨ值监测可用于小儿ＧＥＲ的诊断、分析和疗效评定。

窒息后新生儿胃食管返流初步观察

近年来人们开始关注围产期窒息对新生儿消化系统的影响。但窒息后新生儿发生胃食管返流(gastroesophagealrefulx ,GER)的研究国内报道较少 ,为此 ,我们采用24h食管pH监测技术动态监测窒息后新生儿 ,以了解窒息后新生儿发生GER的时间、性质 ,为临床治疗GER提供理论基础 ,报道如下。资料与方法一、临床资料分为窒息组和对照组 ,均为2001年3～9月间收入我院新生儿病房的足月新生儿。窒息组30例 ,男18例 ,女12例 ,平均胎龄40周 ,平均体重3210g。根据新生儿窒息评分标准[1],分为重度窒息7例 ,轻度窒息23例 ;对照组15例 ,男9例 ,女6例 ,平均…     

胃食管双pH监测小儿十二指肠胃食管返流

采用胃、食管双ｐＨ电极对２１例１～１２个月小儿进行２４ｈｐＨ值监测。７例无返流小儿为对照组，１４例有返流的小儿中９例为酸性返流（６４％），５例（３６％）为碱性返流即十二指肠胃食管返流（其中４例合并酸性返流）。碱性返流可引起严重的食管病变。传统的单一食管下端ｐＨ监测难以作出准确诊断，增加胃底ｐＨ监测为准确判定返流，特别是十二指肠胃食管返流提供重要根据，对于提高胃食管返流诊断率和指导临床对不同类型的返流进行有效治疗具有重要意义。

??The 24-hour intraesophageal pH monitoring is a widely used method in diagnosis of gastroesophageal reflux diseases. It has been regarded as the diagnositic standard of these diseases. Due to the technical limitation?? the traditional pH monitoring can only show the acid refluxes in the lower esophagus instead of the mixed and alkaline ones. As a result?? there is inevitably a proportional rate of misdiagnosis in the traditional pH monitoring. The 24-hour gastric and esophageal double pH monitoring can perfectly solve this problem. In this method?? both the gastric and esophageal pH is recorded for 24 hours. Both the acid refluxes in the lower esophagus and the duodenogastric reflux and the mixed and alkaline refluxes can be clearly demonstrated. With improvement of accuracy?? the 24-hour gastric and esophageal double pH monitoring has been used in adults and adolescent?? but rarely in the neonates. In this paper??the key point of this method and its application in neonates and prematures was reviewed and introduced.     

24 h食管pH监测在婴儿难治性肺炎中的临床应用研究

目的探讨24h食管pH监测在婴儿难治性肺炎中的临床应用及其意义。方法对57例难治性肺炎患儿进行24h食管pH监测,监测指标包括食管pH〈4.0的次数、反流时间≥5min的次数、最长反流时间、卧位pH值〈4的时间占总监测时间的百分比和Biox-Ochoa评分。结果57例中存在胃食管反流（GER）28例（占49.1%）;有呕吐与无呕吐症状患儿各项反流指标比较差异有统计学意义;伴有胃食管反流患儿经促动力剂治疗者,肺部罗音消失时间和咳嗽持续时间均较未用促动力剂治疗者短,差异有统计学意义（P〈0.05）。结论难治性肺炎患儿经正规抗炎治疗效果不佳者,应考虑是否合并胃食管反流,进行24h食管pH监测,以确定病因并指导治疗。     

近端食管胃酸反流与胃食管反流患儿呼吸道症状的关系

目的了解胃食管反流(GER)患儿近端食管胃酸反流与呼吸道症状发生的关系。方法采用食管双pH动态监测法，对31例单纯性呕吐、23例伴有反复呼吸道症状的GER患儿同时监测食管近端和远端pH值的变化，以35例健康儿作为对照组。结果单纯呕吐组远端食管各项酸反流指标、近端食管酸反流指标除最长反流时间外均大于对照组，差异有显著性；呼吸道症状组远端食管、近端食管各项酸反流指标均大于对照组，差异有显著性；但单纯呕吐组与呼吸道症状组相比较，无论在近端食管还是在远端食管，各项指标的差异无显著性；病例组远端食管各项酸反流指标均大于近端食管，差异有显著性。结论近端食管酸反流并不是GER患儿发生呼吸道症状的主要因素，而远端食管酸反流是小儿GER的主要反流形式。

??Abstract??Objective To investigate the characteristics of gastroesophageal reflux disease ??GERD?? with chronic cough by 24-hour ambulatory esophageal impedance-pH monitoring in children. Methods From February 2012 to July 2013?? 40 cases of inpatients and outpatients in Nanjing Children′s Hospital Affiliated to Nanjing Medical University?? who were suspected with gastroesophageal reflux cough ??RERC????were recruited??all these cases underwent 24-hour ambulatory esophageal impedance-pH monitoring. Results Among the 40 children with chronic cough?? 23 patients were diagnosed with GERD refering to pH monitoring??34 children were diagnosed with GERD by 24-hour ambulatory esophageal impedance-pH monitoring. Esophageal acid reflux were significantly higher in the upright than supine position ??P??0.05????and the characteristics of GERD with chronic cough was mainly weak acidic reflux and acid reflux in the upright ??P??0.05????the mixed reflux was the highest frequency in the upright ??P??0.05??. There was no difference between in the upright and supine position about the bolus clearance time??proximal reflux in the supine position was the main way in the total reflux ??P??0.05??. The total reflux and SI demonstrated positive correlation??r = 0.818?? P??0.05??. Conclusion Acid reflux?? weak acid reflux and non-acid reflux can be detected by 24-hour ambulatory esophageal impedance-pH monitoring. The 24-hour ambulatory esophageal impedance-pH monitoring can make more accurate diagnosis of GERD in chronic cough children??and it may have a good prospect for clinical application.

小儿慢性咳嗽与胃食管反流的关系

目的探讨小儿慢性咳嗽与胃食管反流(GER)的关系。方法对170例慢性咳嗽患儿进行24h食管pH监测,32例无症状小儿作为对照。结果病例组各项食管酸反流指标如酸反流次数、反流≥5min次数、最长反流时间、酸性反流指数及Boix-Ochoa综合评分均高于对照组,差异有统计学意义(Z=3.025～4.661,P均<0.01)。根据GER诊断标准,病例组GER检出率为37.1%(63/170例),高于对照组的3.1%(1/32例),差异有统计学意义(χ2=14.327,P<0.01)。2个月～1岁组、～3岁组和>3岁组的GER阳性率分别为47.4%(27/57例)、41.5%(17/41例)和26.4%(19/72例),差异有统计学意义(χ2=6.453,P<0.05)。结论GER与小儿慢性咳嗽关系密切,尤其是3岁以下的婴幼儿;食管pH监测对于明确小儿慢性咳嗽的原因有重要的临床价值。     

Oesophageal pH monitoring and reflux oesophagitis in irritable infants

Acid reflux and/or oesophagitis may be responsible for inconsolable crying in infants. We evaluated prospectively the presence of acid reflux disease, oesophagitis and the accuracy of pH monitoring in the prediction of oesophagitis in a population of irritable infants. A 24-h oesophageal pH monitoring with a glass electrode and an upper gastro-intestinal tract endoscopy with grasp biopsies were performed in 60 irritable infants, aged 1 to 6 months, not responding to cows milk elimination. The 24-h oesophageal pH monitoring was considered abnormal in 40/60 (66%) babies and histological oesophagitis was present in 26/60 (43%). In the infants with histological oesophagitis, the reflux index (% of the investigation time with a pH <4.0) was >5% in 18/26 (69%). Histology of the oesophagus was normal in 22 of the 40 (55%) infants with an abnormal pH monitoring. The mean reflux index in the group with oesophagitis (12.20%) was significantly higher than in the group with normal histology (8.74) ( P =0.036), although there was an important overlap. The sensitivity and specificity to predict oesophagitis with a reflux index of 5.0% or more was 69.2 and 35.3, respectively. There was not a reflux index which could be related to a clinically useful sensitivity and specificity to predict oesophagitis. Conclusion:acid gastro-oesophageal reflux disease and/or histological oesophagitis were diagnosed in 66% and 43% of irritable infants, respectively. There was no relation between symptoms and abnormal pH metry or oesophagitis; however, the reflux index does not accurately predict oesophagitis and normal histology does not accurately exclude acid gastro-oesophageal reflux disease. Oesophageal pH monitoring and endoscopy provide additional information.Abbreviations GOR gastro-oesophageal reflux - RI reflux index     

小儿慢性咽喉炎与胃食管反流的关系

目的探讨小儿慢性咽喉炎与胃食管反流（GER）的关系。方法对37例慢性咽喉炎患儿进行24h食管pH监测,30例无症状儿作为对照。结果病例组各项食管酸反流指标如酸反流次数、反流≥5min次数、最长反流时间、酸性反流指数及Boix-Ochoa综合评分均高于对照组,差异有统计学意义（Z=2.673～4.144,P均〈0.01）。病例组GER检出率（40.5%,15/37例）高于对照组（3.3%,1/30例）,差异有统计学意义（χ^2=12.617,P〈0.01）。结论GER与小儿慢性咽喉炎关系密切;对常规治疗效果差的慢性咽喉炎患儿要考虑到GER的可能,及时进行有关检测。
