摘要 目的探讨微探头环扫超声内镜检查(EUS)对直肠肿瘤的诊断及其手术治疗方案的选择。方法对2010年8月至2012年8月30例术前直肠肿瘤疾病患者行微探头环扫超声内镜联合探查。参数TNM分期标准进行分期诊断,并与CT、手术后组织病理学结果对比,总结EUS检查诊断分期对治疗方案选择的参考价值。结果在30例直肠肿瘤患者中,直肠癌20例,黏膜下肿瘤10例。直肠癌EUS分期:T1期3例,T2期6例,T3期8例,T4期3例;术后病理证实2例分期过度,2例分期不足;CT分期T1期1例,T2期6例,1r3期10例,T4期3例,手术病理证实4例分期过度,6例分期不足。微探头超声内镜结合环扫型超声内镜对直肠癌T分期诊断综合准确率为80%(16/20),N分期的准确率为78.33%,敏感性和特异性分别为71.43%和91.03%;CT对直肠癌T分期准确率为71.67%(14/20),周围淋巴结转移诊断的准确率为70%,敏感性和特异性分别为85.71%和86.96%黏膜下肿瘤10例,平滑肌瘤4例,类癌3例,脂肪瘤2例,淋巴管瘤1例,全部手术病理证实。结论微探头环扫内镜超声检查是一种有效估计直肠肿瘤诊断方法,对直肠癌肠壁浸润深度并对其进行TN分期的方法,且操作简便、痛苦小、诊断准确率较高。
