摘　　要：目的对比放大染色内镜(MCE)、内镜超声检查术(EUS)术前评估结直肠侧向发育型肿瘤(LST)浸润深度的准确率。方法纳入104例结直肠LST,以病理诊断为金标准,回顾性比较MCE和EUS术前评估结直肠LST浸润深度的准确率。结果MCE和EUS的总体准确率分别为89.4%(93/104)和73.1%(76/104)(P<0.05)。病变大小、检查医生因素会影响EUS评估的准确率(P=0.017,0心3.561;P=0.035,OR二1.399)。在直径较大的结直肠LST病变中,EUS评估的准确率有下降趋势。结论MCE和EUS均为评估结直肠LST病变浸润深度的有效方法。MCE评估结直肠LST病变浸润深度的准确率可能高于EUS。病变直径大、检查医生经验不足可能是影响EUS检查准确率的危险因素。Objective To compare the diagnostic accuracy of magnifying chromoendoscopy ( MCE) and endoscopic ultrasonography ( EUS) for preoperative endoscopic assessment of the invasion depth of colorectal laterally spreading tumour( LST). Methods Data of 104 cases of colorectal LST were included. With the final pathological diagnosis as the golden standard, the accuracies of MCE and EUS for preoperative assessment of the invasion depth of colorectal LST were compared. Results The diagnostic accuracies of MCE and EUS for evaluating the invasion depth of LST were 89. 4%( 93/104) and 73. 1%( 76/104 ), respectively ( P<0. 05). The lesion size and the endoscopist could affect the accuracy of the EUS evaluation (P=0. 017,0R = 3. 561;P= 0. 035, OR = 1. 399). The accuracy of EUS seemed to show a downward trend for colorectal LST of larger diameters. Conclusion Both MCE and EUS are effective for evaluating the invasion depth of colorectal LST, but the accuracy of MCE may be higher than that of EUS. Large diameter of the lesion and the doctor's experience inadequacy may be the risk factors for the accuracy of EUS.
