原发性腹膜后肿瘤

Primary retroperitoneal tumor

目的探讨原发性腹膜后肿瘤的诊断和治疗，总结其手术治疗的经验。方法回顾性分析手术治疗的６７例原发性腹膜后肿瘤病人的临床资料。结果良、恶性肿瘤的发病率大致相等，儿童以畸胎瘤和神经母细胞瘤多见，成人以神经原性良性肿瘤、平滑肌肉瘤和脂肪肉瘤多见。男性恶性肿瘤发病率高于女性（Ｐ＜０．０５），年龄越大恶性肿瘤发病率越高（Ｐ＜０．０２）。Ｂ超和ＣＴ的诊断符合率分别为７０％和７６９％。肿瘤总切除率为６２９％，其中良、恶性肿瘤分别为８７９％和３８２％；术中和术后并发症分别为２６９％和１３４％。结论原发性腹膜后肿瘤的诊断包括定性和定位两方面。诊断一旦明确。

CObjective To explore the diagnosis and treatment of retroperitoneal tumor and to summarize the experience in surgical treatment. Methods The clinical data of 67 cases of retroperitoneal tumor was analysed respectively. Resuslts The incidence of benign tumours was as equal as malignant tumors. Teratomas and neuroblas tumor were often seen in children, while the benign neurogenous tumor, leimyosarcomas and liposarcomas were often seen in adults. A higher incidence of malignant tumor was found in male than in female ( P <0.05). The older patients the higher incidence of malignant tumor was found ( P <0.02). The accuracy diagnosis rate of B US and CT examination was 70% and 76.9% respectively. The resection rate of tumors was 62.7%, including 87.9% in benign tumors and 38.2% in malignant tumors. The complication during or after operation was 26.9% and 13.4% respectively. Conclusions The diagnosis of retroperitoneal tumors includes both pathological character and location. Once the diagnosis is made, surgical treatment should be taken as soon as possible.
