摘　　要：目的探讨超声弹性成像在直肠肿瘤术前T分期诊断中的应用价值。方法128例直肠肿瘤患者，分别行直肠腔内超声（ERus）与弹性成像检查，记录肿瘤局部肠壁浸润深度及周边器官组织侵犯情况（T分期），与手术病理结果作对照分析。结果ERUS与弹性成像检查在T分期总的准确性（69．53％对78．90％）比较差异无统计学意义（P〉0．05），但弹性成像诊断T2期肿瘤的准确性高于ERUS（86．72％对75．00％），弹性成像诊断T3期的准确性亦高于ERUS（89．06％对77．34％），差异均有统计学意义（P〈0．05）。ERUS与弹性成像对T分期诊断过高（13．28％对9．38％）、T分期诊断过低（17．18％对11．72%）的差异无统计学意义（均P〉0．05）。结论超声弹性成像在直肠肿瘤T2、T3期中具有较高的诊断准确性，可弥补直肠腔内灰阶超声的不足，为临床治疗决策提供了依据。Objective To investigate the clinical application value of ultrasound elastography（UE） in preoperative T staging of rectal neoplasm. Methods One hundred and twenty-eight cases of rectal neoplasm patients were selected, and underwent endorectal ultrasonography（EURS） and UE. The T staging was recorded and compared with pathology. Results There were no significant differences in T staging total accuracy between ERUS and UE （69.53% vs 78.90%, P 〉0.05）. But the diagnosis accuracy of T2 staging of UE was higher than that of ERUS （86.72 % vs 75.00%, P = 0. 017）, and the diagnosis accuracy of T3 staging was also higher than that of ERUS （89.06% vs 77.34%, P = 0.012）. There were no significant differences in overestimated （13.28% vs 9.38%） and underestimated （17.18% vs 11.72%） of T staging between ERUS and UE （ P 〉0.05）. Conclusions ERUS has a high diagnosis accuracy in T2 and T3 staging of rectal neoplasm, which may make up for the deficiency of endorectal ultrasonography, and provide a new treatment for clinical strategy.
