原发性腹膜后肿瘤的诊治

目的：探讨原发性腹膜后肿瘤的诊断及治疗。方法：回顾分析原发性腹膜后肿瘤101例，就其病情、临床表现和治疗特点进行比较。结果：主要症状及体征以腹痛、腹胀（48．5％），腹部包块（43．6％）为主。肿瘤部位以上、下腹为主（64．3％）。中位病程为3月。恶性占60％，以平滑肌肉瘤和脂肪瘤为主，良性占40％，以神经鞘膜瘤和成熟畸胎瘤为主。初治病人的术前确诊率为74．2％，恶性肿瘤切除率为45．8％，良性为71．9％，联合脏器切除有9例。结论：PRT早期诊断困难，B超和CT是检查PRT的重要手段。PRT应尽可能手术完整切除，如有邻近脏器受累， 亦可一并行联合脏器切除，对提高治愈率及延长患者生存期有利。

DIAGNOSIS AND TREATMENT OF PRIMARY RETROPERITONEAL TUMOR

Objective:To explore the diagnosis and treatment of primary retroperitoneal tumor(PRT). Method:The clinic characteristics and treatment of. 101 cases of PRT from July 1995 to July 2000 were analyzed Result:Abdominal pain and malaise were the main symptoms(48.5%),and palpable mass was the main signs(43.6%).The major locations were up the iliac arteries(64.3%).Median duration of symptoms was 3 months. Leiomyosarcoma and liposarcoma were the most common malignant tumor,schwannoma and benign embryoma were the main benignant tumor. Correct diagnosis ratio in primary disease were 74.2% before operation.Removal rate in malignant tumor was 45.8%,and 71.9% in benignant tumor . 9 cases required resection of adjacent organs. Conclusion:Earlier diagnosis of PRT is difficult. B-ultrasonography and CT-scans are the main means to diagnose PRT.Complete tumor resection and total excision will contributa to long-term survival of many patients.
