摘  要:目的:探讨非糜烂性胃食管反流病( NERD )和反流性食管炎( RE )的食管动力特点。方法采用单盲、回顾性分析2008年1月至2011年12月因反流症状接受食管动力检查的患者资料,根据消化内镜结果分为NERD组和RE组。探讨两组患者病程、年龄、性别、食管动力、食管裂孔功能及24 h 食管pH监测的特点。通过单因素及多因素非条件Logistic回归分析其相关因素。结果244例符合纳入标准的患者分为NERD组159例和RE组85例。与NERD组比, RE组患者年龄偏大、病程较长[(50.7±1.2)比(46.5±0.9)岁;(4.8±0.5)比(3.4±0.3)年,均P<0.05];两组性别构成比差异无统计学意义( P>0.05)。 RE组下食管括约肌( LES)长度和压力、食管体部远端收缩波幅及有效收缩率均明显低于NERD组[(1.91±0.06)比(2.19±0.04) cm;(6.98±0.31)比(8.54±0.31)mmHg;(56.76±3.21)比(75.57±3.47) mmHg;54.1%(46/85)比76.1%(121/159),均P<0.05],两组LES松弛率及上食管括约肌(UES)功能差异均无统计学意义(均P>0.05)。 RE组合并食管裂孔疝(HH)或食管裂孔松弛(HF)的比例明显高于NERD组[23.5%(20/85)比1.9%(3/159);24.7%(21/85)比11.3%(18/159),均P<0.05]。 RE组患者24 h食管pH监测阳性率、酸反流次数及立位pH<4的百分比明显高于NERD组[59.1%(26/44)比32.5%(38/117);71.0(13.5,119.0)比25.0(8.0,56.0)次;5.0%(0.4%,10.9%)比1.1%(0.2%,5.0%),均P<0.05]。多因素非条件Logistic回归分析显示,与NERD组比较,LES长度、食管体部远端有效收缩率、HH是RE发病的危险因素( OR =2.781、0.037、21.722,95%CI:1.057~7.313、0.009~0.152、5.433~86.845)。结论胃食管交界处抗反流屏障功能及食管体部廓清能力降低是导致RE的重要因素,要重视胃食管交界处的解剖结构异常。Objective To explore the characteristics of esophageal motility in patients with non-erosive disease ( NERD) and reflux esophagitis ( RE).Methods For this single-blind retrospective study , adult patients with typical reflux symptoms underwent esophageal manometry from January 2008 to December 2011.Their course of disease, age, gender, esophageal manometry, hiatal function and 24 h pH monitoring were analyzed by univariate and binary Logistic regression analyses.Results A total of 244 adult patients (RE=85, NERD=159) were enrolled into this study.Age and course of disease were significantly higher in RE group than those in NERD group ((50.7 ±1.2) vs (46.5 ±0.9) yrs,(4.8 ±0.5) vs (3.4 ±0.3) yrs, both P<0.05) while no difference existed in gender ( P〈0.05).Lower esophageal sphincter ( LES) length, LES pressure, peristaltic contraction amplitude of distal esophageal body and rate of effective peristaltic contraction of distal esophageal body were significantly lower in RE group than those in NERD group ((1.91 ±0.06) vs (2.19 ±0.04) cm,(6.98 ±0.31) vs (8.54 ±0.31)mmHg,(56.76 ±3.21) vs (75.57 ±3.47) mmHg,54.1%(46/85) vs 76.1%(121/159), all P〉0.05).However, there was no inter-group difference in LES relaxation rate and upper esophageal sphincter ( UES ) function ( both P 〈0.05).Rate of hiatal hernia(HH)and hiatal flabby(HF) in RE group significantly increased versus NERD group (23.5% (20/85) vs 1.9% (3/159),24.7% (21/85) vs 11.3% (18/159), both P<0.05).Positive rate of 24 h esophageal pH monitoring , reflux number and percent of reflux were significantly higher in RE group than those in NERD group (59.1% (26/44) vs 32.5%(38/117),71.0(13.5, 119.0) vs 25.0 (8.0, 56.0),5.0%(0.4%, 10.9%) vs 1.1% (0.2%, 5.0%), all P〈0.05).Binary Logistic regression analysis showed that LES length , rate of effective peristaltic contraction of distal esophageal body
