目的应用高分辨率食管测压比较pH监测正常与异常非糜烂性反流病(NERD)患者的食管动力学特征。方法按标准选取具有典型胃食管反流症状的NERD患者35例和健康体检者10例,分别行上消化道内镜检查、24 h食管pH监测和高分辨率食管测压。依据动态pH监测Demeester评分将NERD患者分为pH监测异常组和pH监测正常组,比较3组患者食管动力的差异。结果 pH监测异常组食管下括约肌(LES)长度较对照组显著缩短(P<0.05),LES压力(LESP)显著降低(P<0.05),pH监测正常组与对照组比较则无明显差异。pH监测正常组和异常组均存在食管体部动力障碍,表现为食管远端收缩波波幅及远端收缩积分降低和有效蠕动比例减少,pH监测异常组改变更为明显。结论 pH监测不同NERD患者间存在食管动力特征差异,pH监测异常NERD组患者存在LES长度和压力异常,食管远端动力障碍更为明显。     

无症状贲门松弛患者酸反流食管动力检测及意义

目的:探讨无反流症状贲门松弛对胃食管酸反流及食管动力的影响.方法:对25例内镜下贲门松弛且无明显反流症状患者及10例内镜检查正常的无症状健康志愿者均进行24 h食管pH监测及食管测压检查.结果:内镜下贲门松弛组24 h食管pH监测各项指标较正常对照组增高, 其中以pH<4总时间及DeMeester评分差异更明显(38.44±50.89min vs 10.60±7.75 min, 11.98±14.84 vs 5.06±3.19, 均P<0.05). 贲门松弛组病理性酸反流发生率较正常对照组差异有统计学意义(28%vs 0%, P<0.05). 两组食管测压各项指标包括LES静息压、LES长度、食管远近端蠕动波幅、食管体部传导速度、湿咽成功率等较对照组低, 但差异无统计学意义.结论:贲门松弛易于发生酸反流, 部分贲门松驰且酸反流患者无相关临床症状.     

健康志愿者和胃食管反流病患者食管动力的性别差异

背景：食管动力受多种因素影响，性别因素对食管动力的影响尚不清楚。目的：探讨健康志愿者、非糜烂性反流病（NERD）和反流性食管炎（RE）患者食管动力的性别差异。方法：83例健康志愿者以及具有典型胃食管反流症状的NERD患者196例和RE患者104例纳入本研究。受试者行食管测压，测定下食管括约肌压力（LESP）和食管体部运动功能（包括食管体部各段蠕动收缩波幅、蠕动波传导速度和湿咽成功率）。结果：RE组男性患者比例显著高于NERD组（69．2％对43．4％，P〈0．05）。健康对照组和NERD组男性基础LESP较女性显著降低（P〈0．05），男性健康志愿者食管体部近端蠕动收缩波幅显著低于女性（P〈0．05），男性RE患者湿咽成功率显著低于女性患者（P〈0．05）。男性NERD患者LESP降低发生率显著高于女性患者（45．9％对29．7％，P〈0．05），男性RE患者食管体部运动功能障碍发生率显著高于女性患者（68．1％对46．9％，P〈0．05）。结论：无论是胃食管反流病（GERD）患者还是健康志愿者，男性的食管动力均较女性差，男性性别是GERD发病的危险因素之一。     

轻度反流性食管炎与非糜烂性反流病远端食管酸暴露和食管动力学变化

目的:探讨轻度反流性食管炎(RE)与非糜烂性反流病(NERD)食管远端酸暴露及食管动力变化特点.方法:符合洛杉矶诊断标准的RE30例(LA-A16例,LA-B14例),NERD16例,健康对照组10例被纳入本研究,所有患者及对照组均接受24h食管pH监测及压力测定,比较食管pH监测及测压结果.结果:LA-A组、LA-B组、NERD组DeMeester评分明显高于对照组,差异显著(P<0.05).LA-A组与NERD组比较DeMeester评分无明显差异,但NERD组的立位反流时间百分比与长反流周期数多于LA-A组,差异显著;LA-B组DeMeester评分比LA-A组和NERD组明显增高,LA-B组与LA-A组比较食管pH监测各项指标均存在明显差异.LA-A组、NERD组及对照组比较下食管括约肌静息压(LESP)、食管体部蠕动波幅度(PA)无显著差异,LA-A组和NERD组食管下段PA有增高趋势;LA-B组与LA-A组、NERD组及对照组比较LESP明显降低(P<0.05),LA-B组食管下段PA明显低于LA-A组(P<0.05).RE组无效食管运动(IEM)明显高于对照组,差异显著.结论:轻度RE(LA-B)与NERD远端食管酸暴露存在差异.DeMeester评分、LES功能不全及食管蠕动功能障碍与RE的严重程度呈正相关.LES功能不全及食管蠕动功能障碍可能不是轻度RE(LA-A)及NERD的主要致病因素.IEM与RE关系密切,且与RE有关的食管动力异常主要为IEM.     

胃食管反流病患者酸反流与食管运动功能障碍的关系

背景：异常酸反流和食管运动功能障碍与胃食管反流病（GERD）密切相关。目的：研究GERD患者的食管运动和酸反流与食管黏膜损害的关系，以及两者之间的相关性。方法：选取有反酸、烧心、胸痛等典型胃食管反流症状的患者72例行上消化道内镜检查、食管测压和24hpH监测。根据pH〈4总时间百分比〈4．5％且DeMeester计分〈14．7的标准。将食管炎患者分为生理性酸反流组（pH^-组）和病理性酸反流组（pH^＋组）。结果：内镜下食管炎组24hpH监测各项指标较无食管炎组显著增高（P〈0．05），病理性酸反流的发生率显著高于无食管炎组（P〈0．01）。两组食管测压各项指标无显著差异，食管炎组pH^＋者的食管下括约肌压力（LESP）较pH^-者显著降低，食管体部蠕动波传导速度减慢，湿咽成功率减少（P〈0．05）。结论：GERD患者食管炎的发生与酸反流密切相关，有病理性酸反流的GERD患者易见食管运动功能障碍。     

非糜烂性胃食管反流病食管酸暴露和雷贝拉唑对其诊断价值研究

Barrett食管、糜烂性食管炎和非糜烂性反流病食管酸暴露及食管动力学分析

目的分析胃食管反流病(GERD)三种亚型Barrett食管(BE)、糜烂性食管炎(EE)和非糜烂性反流病(NERD)患者食管24 h pH监测与高分辨率食管测压结果,探讨不同亚型胃食管反流病食管酸暴露及动力学变化特点。 方法收集2015年12月至2017年12月,新疆维吾尔自治区人民医院接受住院治疗的90例GERD患者的临床资料,其中BE组28例、EE组35例、NERD组27例,通过食管24 h pH监测结果评价患食管酸暴露及反流特点,高分辨率食管测压检查评价食管动力学特点。 结果3组患者年龄及身体质量指数(BMI)等一般资料比较,差异无统计学意义(P>0.05);EE组患者24 h食管pH监测中pH≤4(酸反流)、40.05);3组Demeester评分比较,差异无统计学意义(P>0.05);LES长度3组无明显差异,BE组LES静息压及残余压较EE组和NERD组稍高,但差异无统计学意义(P均>0.05);3组在食管远端收缩积分比较,差异无统计学意义(P>0.05)。 结论食管测酸检查在GERD临床亚型的鉴别方面并无显著差别;Barrett食管、糜烂性食管炎、非糜烂性反流病均存在抗反流屏障功能减退,但不同程度的食管粘膜损伤对食管动力学的影响并无差异。     

老年胃食管反流病患者高分辨率食管测压压力特点分析

目的探讨老年胃食管反流病患者高分辨率（HRM）测压压力特点。方法2011年6月至2012年9月对反酸、烧心伴胸骨后不适等症状的老年患者行HRM检测,分析其食管动力特点。结果老年反流性食管炎（RE）组的下食管括约肌（LES）总长度、腹腔内LES长度、LES平均静息压分别为（2．50±0．62）cm、（1．90±0．19）cm和（21．48±8．48）mmHg,低于老年非糜烂性反流病（NERD）组的（3．33±0．43）cm、（2．50±0．46）cm和（24．83±O．64）mmHg（P〈0．05）。结论老年RE患者存在明显的抗反流机制障碍,在其发病机制中可能发挥重要作用。而老年NERD患者的食管运动功能失调不明显,推测其他机制可能参与了其发病过程。

无效食管动力在非糜烂性反流病中的作用及其与酸暴露的相关性

目的探讨无效食管动力(IEM)在非糜烂性反流病(NERD)诊断中的作用及其与酸暴露的关系。方法回顾性选择2013年3月至2019年5月于吉林大学第一医院行胃镜、食管高分辨率测压(HRM)、24 h pH值监测的具有GERD样症状,且胃镜检查无食管黏膜和结构异常改变的患者,基于罗马Ⅳ诊断标准重新评估,诊断分型为NERD、反流高敏感(RH)、功能性烧心(FH)。分析比较IEM患者食管HRM和酸反流相关参数的变化。统计学方法采用采用独立样本t检验、非参数检验和卡方检验。结果共收集228例患者资料,排除食管胃连接部(EGJ)流出道梗阻和重度食管动力障碍患者37例(8例贲门失弛缓症、9例EGJ流出道梗阻、4例远端食管痉挛、14例无效收缩、2例高收缩食管)、内镜下反流性食管炎53例(洛杉矶分级A级20例、B级15例、C级13例、D级5例)。最终138例患者入组,男60例,女78例,年龄为(50.1±14.1)岁,包括NERD 36例,RH 44例,FH 58例。按照食管HRM芝加哥分类标准将138例患者分为IEM组(46例,其中NERD 15例,RH 12例,FH 19例)和测压正常组(92例,其...

Erosive esophagitis and nonerosive reflux disease (NERD): comparison of epidemiologic, physiologic, and therapeutic characteristics

Nonerosive reflux disease (NERD) and erosive esophagitis are the main presentations of gastroesophageal reflux disease. However, NERD is the most common presentation of gastroesophageal reflux disease in community-based patients. Patients with NERD differ in demographic characteristics from patients with erosive esophagitis, primarily in sex distribution, weight/body mass index, and prevalence of hiatal hernia. Physiologically, patients with NERD tend to have normal lower esophageal sphincter resting pressure, minimal esophageal body motility abnormalities, low esophageal acid exposure profile and minimal nighttime esophageal acid exposure. Patients with NERD have a lower symptom response rate to proton pump inhibitor once daily than patients with erosive esophagitis. Additionally, NERD patients demonstrate a longer lag-time for symptom resolution and lack of difference in symptom response rate between half to full dose proton pump inhibitor as compared with patients with erosive esophagitis.     

��������θʳ�ܷ������������Ƶ��о�

目的探讨非糜烂性胃食管反流病不同于反流性食管炎的发病机制。方法选择1996～2004年北京大学人民医院因反酸、胃灼热感等反流症状确诊为胃食管反流病患者57例,按照内镜下食管黏膜有无破损分为非糜烂性胃食管反流病组和反流性食管炎组,比较两组的一般情况、反流症状、是否合并H.pylori(Hp)感染,以及食管动力测定和食管胃24hpH监测结果。结果两组患者年龄、性别、烟酒嗜好等一般情况及合并Hp感染情况比较差异无显著性。非糜烂性胃食管反流病组不典型反流症状(胸骨后痛)的发生率明显高于反流性食管炎组。两组患者都存在病理性酸反流,但两组患者之间酸和(或)碱反流比较无差异。非糜烂性胃食管反流病患者的食管体部各段蠕动波峰值明显高于反流性食管炎患者。非糜烂性胃食管反流病患者卧位胃酸分泌高于反流性食管炎患者。结论非糜烂性胃食管反流病的不典型反流症状发生率更高。在两组发病机制异同上,反流的强弱并非主要因素,重要的是食管防御机制的差别。     

Relevance of ineffective esophageal motility and hyperactive acid sensitization in patients with gastroesophageal reflux

BACKGROUND AND AIM: Esophageal motor abnormalities including ineffective esophageal motility (IEM) and visceral hypersensitivity have been frequently observed in patients with gastroesophageal reflux. The aim of this study was to observe the incidences of hypersensitivity to acid infusion and motor abnormalities in non-erosive reflux disease (NERD) compared with erosive esophagitis. METHODS: We performed upper GI endoscopy, an acid perfusion test and esophageal manometry on 113 NERD patients and 37 erosive esophagitis patients. RESULTS: The frequency of acid sensitization was 69.9% in NERD and 67.6% in erosive esophagitis. The frequency of esophageal motor abnormality in patients with erosive esophagitis (48.6%) was higher than in patients with NERD (25.7%, P = 0.014). The most frequent esophageal motor abnormality was IEM. The frequency of IEM was 15.9% in NERD patients, 42.9% in Los Angeles grade A, 53.8% in Los Angeles grade B and 66.7% in Los Angeles grade C esophagitis (chi(2) = 16.67, P < 0.0001). CONCLUSION: Our results suggest that no difference exists between visceral hypersensitivity in patients with NERD and those with erosive esophagitis, and that IEM occurs in NERD as well as erosive esophagitis patients. The occurrence of IEM is associated with the endoscopic severity of gastroesophageal reflux disease.     

Healing of severe reflux esophagitis with PPI does not improve esophageal dysmotility

Esophageal dysmotility is frequently associated with gastroesophageal reflux disease (GERD). The aim of this study was to investigate the relationship between the severity of reflux esophagitis and esophageal dysmotility and evaluate the effect of prolonged treatment with proton pump inhibitor (lansoprazole 30 mg/day) on esophageal motility in patients with severe reflux esophagitis associated with esophageal motility disorder. Twelve healthy subjects (HS) and 100 patients with reflux disease were involved in the study consisting of two parts: (i) comparison of esophageal motility in HS and patients with non-eroseive reflux disease (NERD), mild esophagitis and severe esophagitis; (ii) effect of 3-6 months lansoprazole therapy on esophageal motility in 23 patients with severe esophagitis, pathologic acid reflux and esophageal peristaltic dysfunction. Results included the following. (i) Esophageal dysmotility was noted in both patients with NERD and erosive GERD. (ii) Severe esophagitis was associated with severe esophageal dysmotility. (iii) Healing of severe esophagitis did not improve esophageal dysmotility. The resting lower esophageal sphincter pressure was 3.9 mmHg (range 1.7-20) before treatment and 4.8 mmHg (range 1.2-18.3) after esophagitis healing (P = 0.23, vs. before treatment), the amplitude of distal esophageal contraction was 28.8 mmHg (range 10.9-80.6) before treatment and 33.3 mmHg (range 10.0-72.5) after esophagitis healing (P = 0.59, vs. before treatment) and the frequency of failed peristalsis was 70% (range 0-100%) before treatment and 70% (range 0-100%) after esophagitis healing (P = 0.78, vs. before treatment). Both esophageal motility disorders and acid reflux play important roles in the mechanism of GERD, especially in severe esophagitis. Esophageal dysmotility is not secondary to acid reflux and esophagitis; it should be a primary motility disorder.     

非糜烂性反流病的食管动力与胃动素相关性研究

目的从胃肠激素-胃动素与食管动力方面探讨非糜烂性反流病（NERD）的发病机制。方法健康对照14例、反流性食管炎（RE）和NERD各30例参与试验。RE、NERD经症状评估和内镜诊断、结合24h食管pH动态监测、质子泵抑制剂（PPI）试验诊断入组。采用四通道胃肠功能仪检测食管动力,以下食管括约肌压力（LESP）、食管蠕动波推进速度、食管体部蠕动压力、下食管括约肌的松弛状况来表示;用放射免疫方法检测血浆胃动素（motilin,MTL）水平。结果NERD组胃动素水平较正常对照组明显降低（P〈0.01）,与RE组比较无显著性差异（P〉0.05）;LESP在NERD组、RE组、正常对照组间无显著性差异（P〉0.05）;食管蠕动波推进速度、食管体部蠕动压力、下食管括约肌的松弛状况在各组间无显著性差异（P〉0.05）;NERD组、RE组、正常对照组分别分析胃动素与各项动力学指标相关性,P均大于0.05。结论NERD患者的食管动力学改变与RE、正常对照并无区别,食管动力学各项指标与胃动素水平也不存在相关性;NERD、RE组胃动素水平明显低于正常对照组,胃动素在NERD的发生机制中可能起一定的作用。

Analysis of Esophageal Motility and Reflux Characteristics in Patients with Gastroesophageal Reflux Disease With or Without Extraesophageal Symptoms

Background: The pathogenesis of extraesophageal symptoms of gastroesophageal reflux disease is complex, and esophageal motility and reflux may be involved in it. In this study, we aimed to compare esophageal motility and reflux characteristics in gastroesophageal reflux disease patients with and without extraesophageal symptoms by high-resolution manometry and multichannel intraluminal impedance-pH monitoring.Methods: We retrospectively studied gastroesophageal reflux disease patients between January 2014 and December 2018. All patients had undergone high-resolution manometry and multichannel intraluminal impedance-pH monitoring. The results were compared and analyzed.Results: A total of 59 patients were included in this study. Patients were divided into 3 groups according to their main complaint: only typical symptoms (group A, n = 11), both typical and extraesophageal symptoms (group B, n = 33), and only extraesophageal symptoms (group C, n = 15). Compared with group A, the lower esophageal sphincter basal pressure, integrated residual pressure, and lower esophageal sphincter length were lower, and the proximal reflux percentages of a weak acid and non-acid reflux were higher in group B and group C (P < .017). The positive rate of esophageal motility disorders was lower in group A than in other groups (P < .05). The proportion of patients with multiple rapid swallows/single swallow—distal contractile integral ratio greater than 1—was higher in group A than in other groups (P < .05).Conclusions: Decreased lower esophageal sphincter pressure and lower esophageal sphincter length, increased proximal esophageal reflux of weak acid and non-acid reflux, esophageal motility disorders, and decreased peristaltic reserve are involved in the pathogenesis of extraesophageal symptoms of gastroesophageal reflux disease.
