目的总结原发性腹膜后肿瘤的临床特点,诊断和治疗原则。方法回顾1995-2009年41例手术切除病理证实为原发性腹膜后肿瘤的病例的临床资料,结合文献对原发性腹膜后肿瘤患者的临床表现、影像学特点以及治疗结果进行总结分析。结果 2例为单位体检时发现,其余首发症状及体征为腹部肿块、腹痛、腹胀。全部病例均经B超检查,诊断符合率为90.2%(37/41)。CT检查32例,MRI检查5例,阳性率100%。完全切除36例(87.8%),部分切除5例(12.2%),5例患者行联合脏器切除(12.2%)。良恶性肿瘤完整切除率的差异无统计学意义(χ2=0.11,P>0.05)。结论原发性腹膜后肿瘤早期诊断困难。B超和CT、MRI对原发性腹膜后肿瘤的诊断有重要的价值。手术切除是治疗原发性腹膜后肿瘤主要手段,完整切除是治疗成功的关键。
Objective To summarize the clinical features, diagnosis and treatment of primary retroperitoneal tumor. Methods The clinical data of 41 patients with primary retroperitoneal tumor confirmed by pathology from 1995 to 2009 were retrospectively reviewed. The clinical manifestations, imaging features and treatment outcome of patients with primary retroperitoneal tumor were reviewed. Results 2 cases for the unit physical examination found that the remaining first signs and symptoms of abdominal mass, abdominal pain, abdominal distension. All cases were B ultrasound examination, the diagnostic coincidence rate was 90.2% (37/41). CT examination in 32 cases, MRI examination in 5 cases, the positive rate of 100%. Complete resection in 36 cases (87.8%), partial resection in 5 cases (12.2%), 5 patients underwent combined organ resection (12.2%). There was no significant difference in the complete resection rate between benign and malignant tumors (χ2 = 0.11, P> 0.05). Conclusion Primary retroperitoneal tumor is difficult to diagnose early. B ultrasound and CT, MRI diagnosis of primary retroperitoneal tumor has important value. Surgical resection is the primary treatment for primary retroperitoneal tumor. Complete resection is the key to successful treatment.
