超声微探头在大肠癌术前分期中的价值

Value of ultrasonic miniature probe in the preoperative staging of colorectal cancer

目的 探讨超声微探头（UMP）在大肠癌术前分期中的应用价值.方法 应用UMP（Olympus UM-2R,12MHz）术前检测61例大肠癌患者,根据UMP下胃肠壁结构层次和邻近器官浸润情况判断肿瘤侵犯的深度进行T分期.所有病例术后均行病理检查,并与UMP分期进行比较.结果 UMP对大肠癌侵犯管壁深度（T分期）诊断的总准确率为86.9%（53/61）,早期癌诊断准确率高达100.0%（3/3）.UMP分期与TNM分期进行一致性检验,Kappa=0.790,具有较高的一致性.结论 UMP能够比较准确地判断大肠癌浸润深度,对大肠癌术前T分期诊断有一定的临床应用价值,可以为大肠癌患者选择合适的治疗方法提供依据.

Objective To discuss the value of ultrasonic miniature probe （UMP） in the preoperative staging of colorectal cancer.Methods Sixty-one colorectal cancer patients were examined before operation using the UMP （Olympus UM-2R,12 MHz）.According to the intestinal wall structural layers and the close organic infiltration,the tumor encroaching depth was judged and the diagnosis of the T stage was made.All cases got the pathological verification,which was compared with the stage of UMP.Results The general diagnostic accurate rate of tubal wall encroaching depth （T stage） by the UMP was 86.9% （53/61） in the colorectal cancer and the diagnostic accurate rate was 100.0% （3/3） in the early stage cancer.UMP stage and TNM stage showed a better consistency （Kappa=0.790）.Conclusions UMP has high accurate rate in the judgment of the colorectal cancer encroaching depth.There is some value in the T stage diagnosis before operation,which could help patients with colorectal cancer select suitable therapies.
