目的:总结原发性腹膜后肿瘤(PRT)的诊断方法和手术经验.方法:回顾性分析2007年5月至2009年4月38例经手术治疗的PRT患者,总结分析其影像学特点、病理学类型、手术治疗及随访结果.结果:良性肿瘤11例,恶性肿瘤27例,均经病理证实为PRT,肿秘完整切除36例,姑息性切除1例,细针穿刺活检1例;合并脏器切除及血管切除重建11例;复发9例,复发后完整切除8例,姑息性切除1例.随访时间为20～43个月,11例良性肿瘤患者的1、3年生存率分别为100%和90.9%.24例恶性肿瘤患者的1、3年生存率分别为66.7%和33.3%.结论:影像学检查对PRT术前诊断和手术方式的选择具有指导意义,完整切除肿瘤,必要时合并脏器切除及血管切除重建时治疗本病的最有效的方法.%Objective: To summarize the experience in diagnosis and surgical treatment of primary retroperitoneal tumor (PRT). Methods: Clinical data of 38 PRT patients from March 2007 to April 2009 were retrospectively analyzed including image examination, pathologic examination, surgical treatment and follow-up. Results: Tumors were benign in 11 patients and malignant in 27 patients, all of that were diagnosised by pathologic examination. Of the 38 patients, 36 underwent complete resection, 1 uncomplete resection and 1 fine needle aspiration. 11 patients underwent adjacent organ resection and vessel reestablishment. There were 9 recurrent PRT patients, 8 of them underwent complete resection, 1 underwent uncomplete resection. The time of follow-up were 20 to 43 months, the one-year and three-year survival rate of 11 benign PRT were 100％ and 90.9％respectively. The one-year and three-year survival rate of 24 malignant PRT were 66.7％ and 33.3％respectively. Conclusion: Preoperative image examination is crucial for diagnosis and operative modus. The most effective treatment of PRT is complete resection, an adjacent organ resection and vessel reestablishment if necessary.
