目的探讨原发性腹膜后肿瘤的诊断方法和治疗对策。方法回顾性分析68例原发性腹膜后肿瘤的临床特征及手术方法。结果本组手术切除60例，完整切除29例，占48．33％。肿瘤整块切除加扩大切除13例，占21．67％。肿瘤部分切除12例，占20．0％。探查活检6例，占10．0％。其中良性肿瘤21例。占35．0％。恶性肿瘤39例，占65．0％。，结论原发性腹膜后肿瘤，主要依靠影像学诊断，超声和CT为首选诊断方法。造影和X钱可加深对肿瘤的认识。早期诊断和根治性手术仍是提高腹膜后肿瘤患者生存率的有效方法。
Objective To explore the diagnostic methods and treatment strategies of primary retroperitoneal tumors. Methods The clinical features and surgical methods of 68 primary retroperitoneal tumors were retrospectively analyzed. Results In this group, 60 patients underwent surgical resection and 29 patients underwent complete resection, accounting for 48.33%. Tumor en bloc resection and enlarged resection in 13 cases accounted for 21.67%. Partial tumor resection in 12 cases, accounting for 20.0%. Exploration biopsy in 6 cases, accounting for 10.0%. Of these, 21 cases were benign. Accounted for 35.0%. There were 39 cases of malignant tumors, accounting for 65.0%. , Conclusions Primary retroperitoneal tumors rely mainly on imaging diagnosis, ultrasound and CT as the preferred diagnostic method. Contrast and X money can deepen the understanding of cancer. Early diagnosis and radical surgery are still effective methods to improve the survival rate of retroperitoneal tumor patients.
