这项研究表明,多通道阻抗/pH传感器可以测量食道过渡 (EZT),以解释食障碍并预测吞结果. 经过验证的传感器可以准确地识别患有吞困难的患者的食道清除不良.
科学领域:
- 胃肠病学 胃肠病学
- 诊断技术 诊断技术的使用
- 吞障碍 吞障碍 吞障碍
背景情况:
- 多通道阻抗/pH (MII/pH) 监测是评估食道功能的标准工具.
- 使用MII/pH传感器测量食道阻抗过渡 (EZT) 为评估食道运动提供了一种新的方法.
- 消化不良或吞困难通常与食道清除受损有关.
研究的目的:
- 验证使用MII/pH传感器测量食道阻抗传输 (EZT) 的使用.
- 为了比较患有失消症症状和没有失消症症状的患者的EZT.
- 为了将EZT与吞 (BS) 研究结果对食道过渡和保留进行相关联.
主要方法:
- 接受MII/pH测试的患者迅速消耗200毫升盐水来测量EZT.
- 消化管 pH 监测用于排除在 EZT 测量期间的胃酸反流.
- 统计分析包括t测试,奇二测试,ROC曲线和回归分析,以比较EZT与临床结果和BS结果.
主要成果:
- 延长的EZT与症状性消化不良 (p < 0.001) 和保留BS测试 (p < 0.001) 有显著的关联.
- 一分钟的远端食道EZT切断预测了81%的敏感性和75%的特异性.
- 距离食道EZT切断期为3.7分钟,预测了BS识别的保留时间,灵敏度为79%,特异性为93%.
- 增加的远端食道EZT与失消症严重程度正相关 (r = 0.67,p < 0.001).
结论:
- MII/pH传感器有效测量食道过境,为EZT评估提供一个平台.
- 通过EZT测量,可以通过识别食道清除不良的情况来阐明消化不良.
- 这种方法显示了预测与食道过渡和保留有关的吞研究结果的潜力.
