贲门失弛缓症气囊扩张前后食管测压指标的变化 总被引:3,自引:0,他引:3
贲门失弛缓症病因未明 ,多数人认为是迷走神经及其背核和食管壁肌间神经丛神经节细胞变性乃至消失 ,使得食管体部缺少蠕动和下食管括约肌 (LES)松弛不全。我院自1996年起对 35例贲门失弛缓症患者进行了气囊扩张 ,术前常规进行食管测压 ,其中 17例进行Rigiflex气囊扩张后测压复查及随访。现将其食管动力改变情况分析如下。一、资料和方法1 分组 :(1)病例组 :共 35例贲门失弛缓症患者 ,男 2 0例 ,女 15例 ,平均年龄 (38± 2 7)岁 ,所有患者经内镜和食管钡餐确诊为贲门失弛缓症。 (2 )对照组 :共 30例 ,男 13例 ,女 17例 ,平均年龄 (39± 14 … 相似文献

肉毒碱注射治疗食管贲门失弛缓症 总被引:10,自引:0,他引:10
食管贲门失弛缓症 (achalasia)是一种原因不明的食管运动功能障碍性疾病,其主要特征是 :下食管括约肌 (LES)高压、食管缺乏蠕动和对吞咽动作的松弛反应障碍。临床表现为吞咽困难、食物反流以及下端胸骨后不适或疼痛,可伴有体重减轻等表现。本病的治疗主要是通过各种手段降低 LES压力。目前,括约肌切开术和气囊扩张被认为是标准的治疗方法,其不足是有可能并发胃食管反流、出血或食管穿孔;长效硝酸酯类、钙通道阻滞剂等药物尚难达到令人满意的临床效果。最近几年,一种新型的、有希望的治疗手段——食管下括约肌内注射肉毒碱应用于临… 相似文献

经X线、食管测压和内镜确诊贲门失弛缓症57例,突出症状为下咽困难、反流和胸痛。内镜主要表现为食管存有食物和液性滞留物、食管扩张、食管壁轮状收缩环、食管抻长和扭曲,还可见食管胃交接区紧闭,用内镜加压可以推开,反转观察贲门紧抱内镜轴。内镜检查不仅能对本病作出诊断,而且可以排除癌等其它器质性疾病和发现合并症。 相似文献

贲门失弛缓症气囊扩张对食管动力近期和中期的影响 总被引:10,自引:2,他引:10
目的 探讨气囊扩张对贲门失弛缓症患者食管动力的影响及与扩张疗效的关系。方法 4 8例经临床、钡餐造影、内镜检查及食管测压确诊的贲门失弛缓症 ,采用上消化道动力监测系统。观察扩张前和扩张后 4周以及 12~ 2 4周时的症状计分、钡餐造影显示的食管最大宽度、下食管括约肌压力(LESP)、下食管括约肌松弛率 (LESRR)及食管体部收缩振幅。结果 ①扩张后吞咽困难、胸痛和反食症状的计分以及食管的最大宽度均明显低于扩张前 (P <0 .0 5 )。②扩张后 4周、12~ 2 4周 4个方位的LESP明显降低 (P <0 .0 5 ) ,4个方位相应的LESRR扩张后较扩张前明显增加 (P <0 .0 5 )。③扩张前后LESP <2 .6 7kPa次数百分比分别为 4 5 .4 1% ,82 .4 8%和 85 .87% (与扩张前比P <0 .0 5 ) ,LESRR≥80 %的次数百分比分别占 6 .74 % ,5 5 .97%和 4 3.78% (与扩张前比P <0 .0 5 )。④ 4 8例患者中未发现食管体部恢复推进性蠕动波。食管体部收缩振幅扩张前 ,后均表现为无效收缩。结论 ①气囊扩张治疗贲门失弛缓症近期、中期疗效较好 ,并有维持治疗作用。②气囊扩张不仅降低LESP且改善LESRR ,是气囊扩张缓解症状、减少食管扩张程度的重要病理生理改变的基础。提示是否再行扩张的食管动力指标除LESP外 ,还要考虑LESRR。 相似文献

AIM: To assess and compare the esophageal function after peroral endoscopic myotomy(POEM) vs other conventional treatments in achalasia.METHODS: Chart review of all achalasia patients who underwent POEM, laparoscopic Heller myotomy(LHM) or pneumatic dilation(PD) at our institution between January 2012 and March 2015 was performed. Patient demographics, type of achalasia, prior treatments, pre- and post-treatment timed barium swallow(TBE) and high-resolution esophageal manometry(HREM) findings were compared between the three treatment groups. Patients who had both pre- and 2 mo posttreatment TBE or HREM were included in the final analysis. TBE parameters compared were barium column height, width and volume of barium remaining at 1 and 5 min. HREM parameters compared were basal lower esophageal sphincter(LES) pressures and LES-integrated relaxation pressures(IRP). Data are presented as mean ± SD, median [25th, 75 th percentiles] or frequency(percent). Analysis of variance, KruskalWallis test, Pearsons χ~2 test and Fishers Exact tests were used for analysis.RESULTS: A total of 200 achalasia patients were included of which 36 underwent POEM, 22 underwent PD and 142 underwent LHM. POEM patients were older(55.4 ± 16.8 years vs 46.5 ± 15.7 years, P = 0.013) and had higher BMI than LHM(29.1 ± 5.9 kg/m~2 vs 26 ± 5.1 kg/m~2, P = 0.012). More number of patients in POEM and PD groups had undergone prior treatments compared to LHM group(72.2% vs 68.2% vs 44.3% respectively, P = 0.003). At 2 mo post-treatment, all TBE parameters including barium column height, width and volume remaining at 1 and 5 min improved significantly in all three treatment groups(P = 0.01 to P 0.001) except the column height at 1 min in PD group(P = 0.11). At 2 mo post-treatment, there was significant improvement in basal LES pressure and LES-IRP in both LHM(40.5 mm Hg vs 14.5 mm Hg and 24 mm Hg vs 7.1 mm Hg respectively, P 0.001) and POEM groups(38.7 mm Hg vs 11.4 mm Hg and 23.6 mm Hg vs 6.6 mm Hg respectively, P 0.001). However, when the efficacy of three treatments were compared to each other in terms of improvement in TBE or HREM parameters at 2 mo, there was no significant difference(P 0.05).CONCLUSION: POEM, PD and LHM were all effective in improving esophageal function in achalasia at shortterm. There was no difference in efficacy between the three treatments. 相似文献

Perendoscopic pneumatic dilatation in achalasia: Assessment of outcome using esophageal scintigraphy
Brain T. Johnston M.R.C.P. Brendan J. Collins M.D. John S. A. Collins M.D. W. Rodney Ferguson Ph.D. 《Dysphagia》1992,7(4):201-204
Sixteen patients (nine male) underwent perendoscopic pneumatic dilatation for achalasia. The Witzel dilator was chosen as
it allows placement of the balloon under endoscopic vision. Its efficacy was assessed using esophageal scintigraphy. Symptom
score and esophageal transit values at 100 s and after a drink of water all improved significantly (P≤0.014) after dilatation and there was a significant correlation between the improved symptom score and the change in transit
values after 100 s (r=0.586,P=0.017). At follow-up at 8 (3–16) months [mean (range)], 15 of 16 patients (94%) are symptom free. The Witzel dilator is effective
in the treatment of achalasia. Esophageal scintigraphy offers a quantitative assessment of esophageal function, helping the
clinical investigator evaluate new forms of therapy. 相似文献

食管测压在不典型贲门失弛缓症诊断中的应用 总被引:1,自引:0,他引:1
早期或不典型贲门失弛缓症临床诊断较难,X线钡餐检查敏感性较低.该病可能与食管动力障碍有关,食管测压对其诊断可能有较高的价值.目的:通过分析不典型贲门失弛缓症患者的食管测压参数,探讨其特征性表现,为早期诊断提供依据.方法:对21例不典型贲门失弛缓症、15例典型贲门失弛缓症和10名健康对照者进行食管压力测定.结果:不典型贲门失弛缓症组与典型贲门失弛缓症组的LES静息压类似,但均显著高于健康对照组(P<0.01).健康对照组、不典型贲门失弛缓症组和典型贲门失弛缓症组的LES残余压呈递增趋势,且两两比较有显著差异(P<0.01);不典型贲门失弛缓症组仅6例(28.6%)患者LES静息压增加,但有14例(67.7%)LES残余压增加.不典型贲门失弛缓症组50.2%的患者吞咽后LES可完全松弛,松弛率与典型贲门失弛缓症组比较无显著差异,但显著低于健康对照组(P<0.01).食管体部收缩振幅在三组间无显著差异,多数失弛缓症患者湿咽后表现为无传导性同步收缩,与健康对照组比较有显著差异(P<0.01).结论:不典型和典型贲门失弛缓症患者的LES静息压和LES松弛率均显著高于健康对照组,但用于诊断贲门失弛缓症敏感性较低.LES残余压对不典型贲门失弛缓症的诊断有较高的敏感性.吞咽后食管体部无传导性同步收缩是所有贲门失弛缓症患者的特征. 相似文献

Achalasia is a rare esophagus motility disorder. Medical, endoscopic and surgical treatments are available, but all endorse high relapse rates. No data has been published to date reporting a therapeutic effect of cannabis use neither in achalasia nor on its influence on manometric measurements. We report the case of a patient diagnosed with achalasia. He could benefit from a large panel of therapeutic interventions, but none of them was effective over the time. He first used cannabis at age 20 and identified benefits regarding achalasia symptoms. He maintained regular moderate cannabis use for 9 years, with minimal digestive inconvenience. A manometry performed without cannabis premedication was realized at age 26 and still found a cardiospasm. Cannabis use could explain the gap between functional symptoms assessment and manometry measurement. Further investigations are warranted to explore a therapeutic effect of cannabis in achalasia and possible influence on outcome measurements. 相似文献
