本研究旨在建立并验证基于临床和影像学特征的评分系统来预测新生儿黄疸的胆管闭锁风险,并将结果发表在Radiology上。

本研究共纳入了两个中心有新生儿黄疸并行超声(US)和肝胆管闪烁扫描仪(n=480)的患者。一个中心的受试者作为训练组(n = 371),另一中心受试者作为验证组(n = 109)。评价与胆管闭锁的临床和影像学特征。以组织病理学或术中胆管造影作为胆管闭锁的参考标准。利用Logistic回归模型建立预测模型并转化为评分系统。对评分系统进行验证。

结果为,在371例训练组中,97 (26.15%)例患者有胆管闭锁。评分系统包括以下指标:足月产、US中出现三干征、US显示胆囊形态异常、肝胆管闪烁扫描检查中放射性同位素未分泌到小肠中。该评分系统最高为7分。该评分系统在训练组(C统计为0.981,95%CI: 0.970, 0.992)和验证组(C统计为0.995; 95% CI: 0.987, 1.000)能够鉴别胆道闭锁。该系统的风险评分在两组均有较好的稳定性(P = .328和P = .281)。

本研究表明,结合临床和影像学的评分系统能够有助于精确评估先天性黄疸患儿罹患胆管闭锁的风险。
