目的 探讨原发性腹膜后肿瘤 (PRT)的外科治疗经验。方法 分析 1970 2 0 0 0年经手术治疗的 99例PRT ,观察其手术切除及复发等特点。结果 良性 46例 ,恶性 5 3例 ,均经组织病理学证实。良性腹膜后肿瘤 :完整切除率高 (89 13% ) ,很少合并脏器切除 (19 5 6 % ) ,术中失血少 (术中平均输血 10 30mL) ;而恶性肿瘤的完整切除率低 (5 6 6 0 % ) ,合并脏器切除率高 (32 0 7% ) ,术中失血多 (术中平均输血 15 2 0mL)。腹膜后肿瘤复发率14 0 4,复发完整切除率达 6 4 2 8%。结论 手术完整切除肿瘤是治疗的主要手段 ,对复发肿瘤亦应争取再次手术。
Objective To explore the surgical treatment experience of primary retroperitoneal tumor (PRT). METHODS: A total of 99 PRTs that were surgically treated in 1970 were analyzed for their features of surgical resection and recurrence. The results were benign in 46 cases and malignant in 53 cases. All were confirmed by histopathology. Benign retroperitoneal tumors: high rate of complete resection (89 13%), rare organ resection (19.56 %), low blood loss during surgery (average intraoperative blood transfusion of 10 30 mL), and complete resection rate of malignancy (low 5 6 6 0 % ), high organ resection rate (32 0 7%), more intraoperative blood loss (average intraoperative blood transfusion of 152 mL). The recurrence rate of retroperitoneal tumors was 140,4 and the recurrence rate was 64.28%. Conclusion Complete resection of the tumor is the main method of treatment, and reoperation should be performed for recurrent tumors.
