原发性腹膜后肿瘤40例临床诊断和治疗

Clinical diagnosis and treatment in 40 cases of primary retroperitoneal tumor

目的 :总结探讨原发性腹膜后肿瘤的临床表现、诊断及外科治疗经验。方法 :回顾分析 1983～ 2 0 0 1年病理证实的 4 0例原发性腹膜后肿瘤 ;观察腹膜后肿瘤的临床表现、病理类型及手术切除等方面的特点。结果 :腹痛和腹块是主要症状和体征 ,B超、CT及MRI的诊断率分别为 5 2 .6 %、80 %和 10 0 %。第一次肿瘤切除率 5 9% ,其中良性肿瘤为 6 5 .2 % ,恶性肿瘤为 34.8%。第二次手术 7例 ,5例完全切除肿瘤。结论 :B超、CT及MRI对本病的确诊有重要意义 ,但必须紧密结合临床。手术全切除及整块切除是治疗的重要手段 。

Objective:To investigate the clinical manifestations, diagnosis and surgical treatment of primary retroperitoneal tumor(PRT). Methods:fourty cases of PRT diagnosed pathologically from 1983 to 2001 were retrospetively analyzed. Clinical manifestations,pathological types and operative resection were observed.Results:Abdominal pain and mass were the main symptoms and signs. The diagnostic rate by B-ultrasonography, CT and MRI was 52.6%, 80% and 100% respectively. Total surgical rescetion rate was 59%(83.3% for benign and 38.1% for malignant)in their first surgery. Among the 7 patients re-operated, 5 received total resecton.Conclusion:B-ultrasonography, CT and MRI examinations are crucial for the diagnosis of PRT. But they must be closely conneted with clinical manifestations. The total resection and enbloc resetion are the best way of treatment. Re-operation was the first choise for recurrent PRT.
