Abstract： 目的:探讨经直肠腔内超声(TRUS)对直肠癌术前分期的诊断价值及其与TNM分期的关系.方法:对65例经病理证实为直肠癌的患者术前进行TRUS检查, 记录癌肿浸润周径, 同时采用TNM分期标准进行分期, 并与术后TNM分期进行对照.结果:65例直肠癌术前TRUS检查总的诊断准确率为86.15%, T1-T4期TRUS诊断准确性分别为 93.85%、87.69%、90.77%及100%, 直肠癌癌肿浸润周径与TNM分期间呈正相关(r =0.89, P <0.01), 结合直肠癌癌肿浸润周径程度可以使直肠癌术前分期总的诊断准确率明显提高(95.38%).结论:TRUS检查对于直肠癌术前分期有较高的诊断准确性, 有助于制定合理的治疗方案,结合直肠癌组织浸润周径可提高术前分期诊断准确性.
