摘要
目的:探讨直肠腔内超声(TRUS)对直肠癌术前分期的诊断价值及其与术后病理分期的关系。方法:对46例结肠镜活检经病理证实的直肠癌的患者术前进行TRUS检查,记录癌肿浸润深度和区域淋巴结检出率,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:46例直肠癌术前TRUS检查对直肠癌T分期诊断准确率为89.1%(41/46),N分期准确率为86.2%(25/29),敏感性为92.6%(25/27),特异性为78.9%(15/19)。术前TRUS分期与术后分期对Ⅰ期和Ⅱ期或以上直肠癌判断的准确性间无显著性差异(p>0.05)。结论:TRUS检查对于直肠癌术前T分期和淋巴结转移有较高的准确性,有助于制定合理的治疗方案,并估计预后。
AIM： To explor the diagnostic value of transrectal ultrasonography（TRUS） inpreoperative staging of rectal carcinoma and the relationship between TRUS and postoperative TNM staging.METHODS： Forty-six patients with pathologically confirmed rectal carcinoma were detected by TRUS before surgery.The status of the bowel wall invasion and lymph-node metastasis of tumor was recorded.The preoperative transrectal ultrasonographic staging of rectal carcinoma was performed using the TNM staging system.The preoperative staging results were then compared with those of postoperative pathologic staging with standard AJCC staging system.RESULTS： The overall accuracy rate of preoperative T staging of rectal carcinoma was 89.1%（41/46） and the total N stage accuracy was 86.2%（25/29）,the sensitivity and specificity was 92.6%（25/27） and 78.9%（15/19） respectively by TRUS.The preoperative TRUS staging and the postoperative staging have not significant difference it in evaluation against stagingⅠ and staging Ⅱ or highest（p0.05）.CONCLUSION： TRUS has a high diagnostic accuracy in preoperative staging of rectal carcinoma.TRUS in combination of T staging with the status of lymph-node metastasis by tumor can improve the diagnostic accuracy of preoperative staging of rectal carcinoma.
