10年间经手术和病理证实原发性腹膜后肿瘤35例.X线、B超及CT检查术前阳性率分别为76.6%、86%及100%.作者对三者在诊断原发性腹膜后肿瘤中的意义进行评价,指出B超和CT作为一种非特异性的无创伤检查方法,对于无临床症状或原因不明的腹部肿块是较理想的检查手段,有条件二者均采用;而X线检查,可排除胃肠道或泌尿系占位病变,对证实腹膜后肿瘤诊断,提高术前诊断率及术前估计手术的难易程度仅能提供一定的依据.
In the 10 years, 35 cases of primary retroperitoneal tumors were confirmed by surgery and pathology. The preoperative positive rates of X-ray, B-ultrasonography, and CT were 76.6%, 86%, and 100%, respectively. The authors diagnosed primary retroperitoneum after the three. The significance of the tumor was evaluated and it was pointed out that B-ultrasonography and CT were used as a non-specific non-invasive examination method. It is an ideal examination method for abdominal masses with no clinical symptoms or unexplained causes. Both conditions are adopted; X-ray Examination can exclude gastrointestinal tract or urinary tract lesions. It can only provide a certain basis for confirming the diagnosis of retroperitoneal tumors, improving the preoperative diagnostic rate, and estimating the ease of operation before surgery.
