腔内超声对直肠癌术前分期的诊断价值

目的探讨腔内超声(Endoluminal ultrasound,ELUS)对术前直肠癌分期评价的临床应用价值。方法对69例直肠癌患者术前进行ELUS检查进行术前分期诊断,并且与术后病理诊断进行对照。结果术前ELUS检查T1期诊断正确率为93.33%(14/15),T2期为83.33%(15/18),T3期为74.07%(20/27),T4期为66.67%(6/9)。ELUS诊断正确率为79.71%(55/69)。ELUS对转移淋巴结诊断总正确率为65.22%(45/69),灵敏度为76.19%,特异度为61.71%。结论 ELUS对于直肠癌癌组织的浸润程度以及周围转移淋巴结诊断与术后病理诊断的正确率较高,有希望成为直肠癌术前分期的有效方法。

Clinical Diagnostic Value of Endoluminal Ultrasound on the Preoperative Staging of Rectal Cancer

Objective To study the clinical value of endoluminal ultrasound(ELUS) in the preoperative staging of rectal cancer.Methods 69 cases of rectal cancer were examined with ELUS before surgery for preoperative staging and compared with the postoperative pathological diagnosis.Results The accuracy of T1,T2,T3,T4 stage of ELUS were 93.33%(14/15),83.33%(15/18),74.07%(20/27),66.67%(6/9),the overall accuracy of T stage of ELUS was 79.71%(55/69).The accuracy,sensitivity and specificity of ELUS in lymph node metastasis were 79.71%,76.19% and 61.71%.Conclusion ELUS should become effective method in the preoperative assessment of depth of tumor invasion and lymph node metastasis compared with pathological diagnosis.
