肾周脂肪肉瘤的诊断和外科治疗

目的 探讨肾周脂肪肉瘤的外科治疗方法。方法 总结分析2000—2006年间收治的28例肾周脂肪肉瘤病人经手术治疗的临床资料。结果 肾周脂肪肉瘤临床主要表现为进行性增大的腹部包块与消化道症状；起源于右肾周17例，左肾周11例。28例全部行手术切除。联合患侧肾脏切除19例，结肠部分切除10例，小肠部分切除8例，胃部分切除2例，脾切除2例，部分膈肌切除、胸腔闭式引流5例。平均输血1870mL。结论 手术切除是目前治疗肾周脂肪肉瘤惟一有效的方法，根治性手术必须包括肿瘤、肾脏和肾周脂肪囊在内的整块切除。

Perirenal liposarcoma: diagnosis and treatment

Objective To explore the appropriate surgical strategy for the treatment of perirenal liposarcoma. Methods The clinical data of 28 cases of perirenal liposarcoma performed operation between 2000 and 2006 were analyzed retrospectively. Results The main clinical features were abdominal mass and compression symptoms. Seventeen tumors originated from the right side and eleven from the left. Tumors were resected in all cases. Among them, 19 cases were performed affected kidney resection. Ten cases were performed partial colon resection. Eight cases were performed partial small intestine resection. Two cases were performed partial stomach resection. Two cases were performed lienectomy. Five cases were performed partial diaphragma resection and thoracic close drainage. The average blood transfusion volume was 1 870 mL. Conclusion Surgical resection is the only effective method for the treatment of perirenal liposarcoma. Preserved kidney is found to be highly related to local recurrence. Therefore, enbloc resection of the tumor with the kidney and adeps renis should be performed in the radical operation.
