目的 总结纵隔肿瘤的诊断和外科特殊处理方法。方法 该组225例纵隔肿瘤中以畸胎瘤、胸腺瘤及神经源性肿瘤居多。手术选择胸骨正中或胸后外侧两种切口入路,肿瘤切除197例,单纯探查活检28例。结果 术后死亡1例。随访2个月～23a,良性肿瘤术后预后良好,无肿瘤复发;恶性纵隔肿瘤术后辅以放疗和(或)化疗,疗效尚满意。结论 ①X线,CT,MRI和胸腔镜是纵隔肿瘤的主要诊治手段,本病一旦确诊应手术治疗。②强调良性肿瘤切除要彻底,防止复发。③对纵隔恶性肿瘤,主张术前或术后辅以放疗或化疗,可提高手术切除和术后生存率
Objective To summarize the diagnosis and surgical treatment of mediastinal tumors. Methods 225 cases of mediastinal tumors in this group were teratoma, thymoma, and neurogenic tumors. Two sternal approaches were selected: median sternotomy or posterior thoracic approach. 197 patients underwent tumor resection and 28 patients underwent biopsy. Results One patient died after surgery. Follow-up of 2 months to 23 years, benign tumors had a good prognosis, no tumor recurrence, and malignant mediastinal tumors supplemented with radiotherapy and/or chemotherapy were still satisfactory. Conclusion 1 X-ray, CT, MRI and thoracoscope are the main methods for diagnosis and treatment of mediastinal tumors. Once the disease is diagnosed, it should be treated surgically. 2 emphasize the thorough removal of benign tumors to prevent recurrence. 3 For mediastinal malignancies, advocating preoperative or postoperative adjuvant radiotherapy or chemotherapy can improve surgical resection and postoperative survival
