    摘 要:目的 总结经验以提高原发性腹膜后肿瘤的术前诊断率、手术切除率和减少手术死亡率. 方法 对我院近年来收治的48例原发性腹膜后肿瘤患者的诊治情况进行回顾性研究. 结果 1992/2000年期间共收治48(男26，女22)例患者.B超检查的确诊率90%;CT扫描的确诊率为96%，但两种检查结果有互补意义.肿瘤的切除率为67%;11例行肿瘤部分切除术;5例未能切除肿瘤而行活检术.10例行联合脏器切除;5例行血管重建术.4例在术中出现难以控制的广泛渗血，经压迫均得以控制.手术死亡率2.1%. 结论 多种影像学检查并用可提高原发性腹膜后肿瘤的诊断率;细致的体检常有诊断意义;扩大手术范围切除受累的脏器和血管不增加手术死亡率，但可提高手术切除率.
