使用新型影像学诊断胃酸反流病:一项前瞻性研究
研究概览
详细说明
胃食管反流病 (GERD) 是退伍军人中常见的慢性疾病,每年的药物成本超过 100 亿美元。 只有30-40%的有反流症状的患者患有糜烂性食管炎。 绝大多数人都患有 NERD;标准内窥镜检查无法识别任何粘膜破裂且无法确认诊断的情况。 不幸的是,不存在诊断 NERD 的金标准。 NERD 患者的 24 小时食管 pH 监测和组织学食管粘膜变化的准确性有限,无法在临床实践中常规使用。
窄带成像 (NBI) 利用光谱窄带滤光片(并入标准内窥镜)并能够对毛细血管内毛细血管环 (IPCL) 等特征进行成像;标准内窥镜检查未发现的特征。 初步结果表明,NBI 内窥镜检查可能比标准内窥镜检查对 NERD 的诊断有显着改进。 我们的假设是 NBI 识别远端食管的变化,这些变化对诊断 NERD 患者具有特异性。 具体目标 1:比较 NERD(病例)和对照组患者远端食管的 NBI 特征。 具体目标 2:确定 NERD 患者的 NBI 特征在 PPI 治疗后是否得到解决。 具体目标 3:将 NBI 结果与食管组织学相关联。 特定目标 4:评估观察者内部和观察者间对诊断 NERD 的建议标准的认可程度。 病例将被定义为具有反流症状的患者(通过两份经过验证的问卷进行评估),没有肉眼可见的糜烂和异常的食管 pH 结果(NERD 组)。 对照受试者将包括没有反流症状、没有肉眼可见的糜烂和食管 pH 结果正常的患者。 为了将 NBI 结果确定为反应的预测因子,将使用经过验证的 GERD 问卷评估随机分配到 PPI 组的病例对治疗的反应,并将其与 IPCL 数量和微糜烂的存在相关联。 此外,NBI 在有反流症状、无肉眼可见糜烂和正常食管 pH 结果的患者中的发现也将与对照组进行比较。 将从远端食道获得两个活组织检查以及数字图像和录像。
统计分析将按如下方式进行: 目标 1 - 卡方和 t 检验;通过逻辑回归和优势比计算,目标 2- McNemar 检验和 kappa 统计,目标 3- Spearman 相关系数和目标 4- 类内相关系数。 对医疗保健的潜在影响:GERD 在患者中很常见,通过避免额外检查的需要和减少不必要的药物成本,NBI 内窥镜检查可能对 NERD 患者产生相当大的积极影响。

描述
纳入标准:
- 18岁
- 能够给予知情同意。
- NERD 病例将根据胃灼热和/或反流的存在进行招募,使用两个经过验证的 GERD 问卷,结合食管 pH 值异常结果和标准内窥镜检查没有糜烂。
- 对照受试者将包括转介进行上消化道内窥镜检查以评估非反流症状的患者,例如缺铁性贫血、血红素阳性粪便、食道静脉曲张筛查等。 阴性食管 pH 结果和没有糜烂将是这些患者的入选标准。
