右腹上部巨大占位性病变中 ,常遇到右肝、右肾上极、右肾上腺和后腹膜来源的肿瘤 ,因上述脏器相互紧邻 ,肿瘤的术前定位定性困难 [1 ,2 ] ,同时毗邻重要血管多 ,处理棘手。笔者 1998年 1月～ 1999年 4月收治 8例患者右腹上部肿瘤≥15 cm并累及重要血管 ,介绍如下。1　资料与方 In the large occupying lesions in the right upper abdomen, tumors of the right liver, right kidney upper pole, right adrenal gland and posterior peritoneum are often encountered.
