摘要 目的回顾性评价经内镜超声微探头检查诊断直肠癌T、N分期的准确率和在直肠癌术前分期方面的应用价值。方法使用12MHz超声微探头进行内镜超声检查(EUS)。选择本院手术治疗的53例直肠癌患者在治疗前接受检查。以手术探查和手术后组织病理诊断结果为标准评价内镜超声检查诊断直肠癌肿瘤浸润深度(T分期)的准确率和局部淋巴结转移(N分期)的准确率。结果经内镜超声微探头检查诊断直肠癌T分期的准确率为79.2%,诊断早期直肠癌T分期的准确率为100%,诊断进展期肿瘤(T2~T4)T分期的准确率为75.0%,诊断直肠癌T分期的准确率不受肿瘤部位、形态、浸润直肠壁范围和患者体质指数(BMI)的影响。EUS诊断直肠癌N分期的准确率、灵敏度和特异度分别为65.1%、20.0%和89.3%。结论经内镜超声微探头检查是诊断直肠癌T分期的准确方法,诊断早期直肠癌T分期的应用价值尤为突出,此方法用于直肠癌术前T分期稳定、可靠,但其诊断局部淋巴结转移的准确率较低。 Objective:To evaluate the accuracy of T and N staging for rectal cancer and the usage of preoperative staging with endoscopic ultrasound probe retrospectively.Methods:The endoscopic ultrasound probe(12 MHz) was used in this study and fifty-three patients with carcinoma of rectum underwent endoscopic ultrasonography(EUS) with this probe.The diagnosing of tumor invasion(T staging) and local lymphatic node metastasis(N staging) was compared with result of operations research and histological stage(pT and pN) o...
