彩超诊断贲门癌及周围浸润与X线及胃镜对比分析

目的评价彩超、X线钡餐透视、胃镜综合应用对贲门癌及周围浸润的诊断价值以及相互关系。方法59例贲门癌患者同时采用彩超、X线、胃镜检查,将其结果与手术、病理结果对照。结果3种检查方法对贲门癌的诊断准确性无明显差异,符合率分别为88.0%,91.5%,98.3%。对周围浸润及淋巴结、肝、胰转移情况,彩超诊断42例、X线检查15例,胃镜19例,敏感性分别为71.1%,25.4%,32.2%,彩超明显优于后二者(P<0.01),且后两者均不能提示胃外淋巴结及周围脏器转移情况。结论彩超检查贲门癌具有较高的术前诊断准确性,特别是对周围浸润转移情况具有X线、胃镜难以代替的优越性。

Diagnosis of cardial cancer and its surrounding invasion with color Doppler ultrasonography associated with X-ray and gastroscopy

Objective To evaluate the value of color Doppler ultrasonography(US),X-ray barium meal examination(X-ray) and gastroscopy(GS)in the diagnosis of the cardial cancer.Methods Fifty nine patients with cardial cancer underwent US,X-ray and GS examinaions before the operation .The preoperative findings of US ,X-ray and GS were compared with the findings of surgery or pathology.Results The preoperative diagnostic accuracy was 88 %for US,91.5 %for X-ray and 98.3 %for GS,respectively,there was not significant difference between above three methods but in the case of invasion and metastasis of lymphonode,liver and pancreas,the detective rate was 71 %(42/59) for US,25.4 %(15/59)for X-ray and 32.2 %(19/59) for GS,respectively,the detective rate of US was significantly higher than that of X-ray and GS(P< 0.01) and latter two methods could not reveal the metastasis of extragastric lymphanodes or distant organs.Conclusion Color Doppler ultrasonography has a higher accuracy in the preoperative diagnosis of cardial cancer in particular for the detection of surrounding invasion or distant metastasis,US has an avantage irreplaceable by X-ray and GS.
