【摘要】：目的评价微探头超声内镜与腹部超声联合应用对提高大肠癌患者的临床分期准确性及特异性的价值。方法应用微探头超声内镜及其与B超联合的检查方法分别对88例大肠癌患者进行术前TNM分期,并与术后病理结果进行比较。结果微探头超声内镜术前大肠癌浸润深度的分期和是否有淋巴结转移与术后病理结果分期的总符合率分别为78.4%和72.7%,T1、T2、T3和T4的符合率分别为88.9%、73.9%、80.6%和76.0%;无淋巴结转移(N-)和有淋巴结转移(N+)的符合率分别为75.0%和71.9%。微探头超声内镜与B超联合对淋巴转移的准确度、敏感度及特异性均高于单独应用微探头超声内镜检查,但差异无统计学意义。结论微探头超声内镜是大肠癌浸润深度分期的有效手段之一,结合其他影像学检查有助于提高TNM分期准确性。
[Abstract]:Objective to evaluate the clinical accuracy and specificity of endoscopic microprobe combined with abdominal ultrasound in patients with colorectal cancer. Methods the preoperative TNM staging was performed in 88 patients with colorectal cancer by microprobe endoscopy and combined with B-ultrasound, and the pathological results were compared with those after operation. Results the coincident rates of depth of invasion and lymph node metastasis before endoscopic ultrasound were 78.4% and 72.7%, respectively. The coincidence rates of T _ 3 and T _ 4 were 88.9% and 76.0%, respectively. The coincidence rates of lymph node metastasis N) were 75.0% and 71.9%, respectively. The accuracy, sensitivity and specificity of microprobe endoscopic ultrasonography combined with B-ultrasound for lymphatic metastasis were higher than that of microprobe ultrasound endoscopy alone, but the difference was not statistically significant. Conclusion microprobe endoscopy is one of the effective methods for the invasive depth staging of colorectal cancer. Combined with other imaging examinations, the accuracy of TNM staging can be improved.
