摘要 目的探讨内镜下窄带成像技术(NBI)对结直肠息肉样病变的诊断价值。方法经高清晰NBI内镜观察724例患者的结直肠息肉样病变,以病理结果为金标准,评价NBI判断结直肠肿瘤性及非肿瘤性息肉的价值。结果 NBI内镜发现息肉样病变776处,病理提示非肿瘤性336处、肿瘤性440处。NBI诊断结直肠肿瘤性息肉的敏感度、特异度、阳性预测值、阴性预测值及准确率分别为90.9%、85.7%、89.3%、87.8%、88.7%;对结直肠微小息肉、小息肉和大息肉诊断肿瘤性息肉的准确率分别为85.4%、88.0%和95.8%,差异有统计学意义(χ2=13.93,P=0.001)。结论 NBI能较好地识别结直肠肿瘤性和非肿瘤性息肉样病变。
