摘　　要：目的探讨超声内镜（EUS）在直肠癌诊断和分期中的价值。方法对2005年5月至2008年9月本院收治的56例直肠癌患者进行电子结肠镜和超声内镜检查和分期，并与手术后的病理结果进行对比研究。结果EUS诊断56例患者直肠癌浸润深度（T）的准确率为82％（46／56），诊断早期直肠癌和进展期直肠癌（T2～T4）的准确率分别为71．4％（5／7）和81．6％（40／49）。诊断局部淋巴结转移（N）的准确率、灵敏度和特异度分别为80．4％、75．0％和88．9％。结论超声内镜诊断直肠癌浸润深度及对周围器官侵犯有较高准确性，对直肠癌诊断和分期有较好实用价值。Objective To investigate the value of diagnosis and staging by endoscopic ultrasonography（EUS）for rectal cancer. Methods Fifty-six patients with rectal cancer were diagnosed by and compared with postoperative staging and pathologic identification. Results The accuracy rate of T staging was 82% with EUS,T staging accuracy rate for early stage rectal cancer was 71.4% and 81.6% for advanced tumors （T2--T4 ） respectively. The accuracy, sensitivity and specificity of N staging were 80. 4%, 72.400% and 88.9% respectively. Conclusion EUS has the practical value in diagnosis and staging for rectal cancer.
