摘要： 目的 探讨i-scan内镜在上消化道癌筛查的应用。 方法 将进行上消化道癌筛查的人群随机分为白光模式组和i-scan模式组,各3 000例,比较两组镜下检出病例检出率、随访病例检出率、早诊率及敏感度、特异度。 结果 i-scan模式组检出病例检出率、随访病例检出率与白光模式组相比有统计学差异(χ2=4.41,P<0.05; χ2=4.81,P<0.05)。i-scan模式组检出病例、随访病例的敏感度(82.35%、79.14%)均高于白光模式组(78.13%、65.54%);i-scan模式组早诊率(12.00%)高于白光模式组(6.67%),两组早诊率相比有统计学差异(P<0.05, χ2=4.61)。 结论 i-scan技术提高了上消化道癌及癌前病变的检出率,在上消化道早癌筛查中有很大的应用价值。
