【摘要】 目的 应用X线钡餐造影，测量胃癌病灶的活动度，判断胃癌能否手术切除。 方法 把患者的椎体及其以下椎体间隙的高度作为测量的标准单位，将168例胃癌分为以贲门及胃底为主的上部和以幽门及胃窦为主的下部，分别测量胃癌病灶在立位像和卧位像上的位置，求出两者之间的差别，作为胃癌病灶的活动度。 结果 下部胃癌病灶的活动度>1.00个椎体单位时，完全能够手术切除，≤0.50个椎体单位时，手术切除的可能性极小，胃癌病灶的活动度在0.6～1.0个椎体单位之间时，仍有很大的可能性将胃癌病灶切除掉;上部胃癌不宜用此方法判断能否切除。 结论 X线检查为确定胃癌病灶的活动度提出了一个简便的测量方法，得出了一个术前判断胃癌能否手术切除的客观依据。

    【Abstract】 Objective To measure the activity degree of gastric cancer by X-ray barium perspective and judge the feasibility of excision.Methods Take the height of a centrum and a clearance between two centrums as a standard metrical unit.Separate the168cases into nether gastric cancers and upper gastric cancers.Measure the posi-tions of gastric cancers in standing location image and lying location image，take the difference between the two posi-tions as the activity degree.Results The nether gastric cancer can be excised completely if the activity degree is more than1.0centrumunits ......
