原发性骶前肿瘤的诊断与手术治疗（附8例临床分析）

Diagnosis and Surgical Treatment of Primary Sacroanterior Tumor：Clinical Analysis on 8 Cases

为探讨原发性骶前肿瘤的诊断和手术方法，分析2007-2010年治疗的8例原发性骶前肿瘤患者的临床资料。结果显示，5例经骶尾部切除，1例经腹切除，1例经腹骶联合切除，1例经腹会阴联合切除。术后病理类型：表皮样囊肿2例，皮样囊肿（良性畸胎瘤）1例，脂肪瘤1例，平滑肌瘤1例，淋巴管囊肿1例，恶性纤维组织细胞瘤1例，恶性畸胎瘤1例。术后无严重并发症。随访12～24个月，无死亡病例。结果表明：（1）直肠指诊、直肠腔内超声、CT检查、MRI检查对术前评估有重要意义；（2）原发性骶前肿瘤应行手术切除，根据肿瘤情况选择手术方法，完整切除肿瘤。
