摘要
探讨内镜超声、微血管计数在大肠癌术前分期的应用及意义,30例大肠癌病人术前作该项检查结果表明,内镜超声诊断癌侵犯肠壁的深度的准确率为76.7%,诊断癌周淋巴结转移的准确率为73.3%,总的术前 Duke's 分期准确率为70%。微血管计数结果显示癌侵犯肠壁达外膜层的比未达外膜层癌的微血管计数高,而且有转移的大肠癌比无转移的大肠癌的微血管计数高。两者都能较正确地反映肿瘤分期,两者结合起来对术前判断肿瘤的分期、评价其预后有重要意义。
30 patients with colorectal carcinoma underwent endoscopic ultrasonography(EUS)and microvessel counting for staging before operation.The accuracy of EUS in assessing depth of tumor in- filtration was 76.7%,that in detecting lymph node involvement being 73.3%.The correctness of pre- operative Duke's staging remained 70%.Microvessel counting correlated with depth infiltration and lymph node invasion.The microvascularity in tumor with serosal involvement was obviously abundant than that without,so as in tumor with and without lymphatic invasion.The results revealed that both EUS and microvessel counting can be considered as an essential evidence for preoperative staging of col- orectal cancer and thereby for predicting prognosis.
