胸腔镜胸腺切除术剑突下入路与侧胸入路的病例对照研究

Subxiphoid video-assisted thoracoscopic thymectomy versus traditional video-assisted thoracic surgery thymectomy for myasthenia gravis: A case control study

目的探讨经胸腔镜胸腺切除剑突下入路治疗重症肌无力的安全性和疗效。方法回顾性分析2014年1月至2016年7月在复旦大学附属华山医院胸外科行胸腔镜下扩大胸腺切除85例患者的临床资料,对比经剑突下入路胸腺切除(subxiphoid approach video-assisted thymectomy,SXVT)与侧胸入路胸腺切除(traditional unilateral approach video-assisted thymectomy,TVAT)的手术时间、术中失血量、术后引流时间、疼痛指数及生活质量等数据。结果全组无围手术期死亡,无中转开胸,术后无患者出现肌无力危象。两组患者在切除标本大小、术中失血量、引流时间、术后引流量、术后住院时间及重症肌无力改善率等方面差异无统计学意义(P>0.05)。SXVT组患手术时间明显短于TVAT组、术后胸痛情况优于TVAT组(P<0.05)。结论胸腔镜经剑突下胸腺切除安全可行,具有手术时间短、术后胸痛症状轻、术后疗效确切等优点,值得推广。

Objective To investigate the clinical outcomes of subxiphoid video-assisted thoracoscopic thymectomy for myasthenia gravis. Methods The clinical data of the 85 patients undergoing video-assisted thoracoscopic thymectomy for myasthenia gravis in Department of Cardiothoracic Surgery, Huashan Hospital affiliated to Fudan University between January 2014 and July 2016 were studied. Subxiphoid approach video-assisted thoracoscopic thymectomy（SXVT） and through traditional unilateral approach video-assisted thymectomy（TVAT） were compared.The clinical outcomes of SXVT and TVAT were compared. Results There was no surgical death and no statistical difference between the two groups in drainage time, postoperative volume of drainage, postoperative hospital stay and bleeding volume during operation（P〉0.05）. However, the acute chest pain after surgery, as well as the postoperative chest pain, and operative time were less in the the SXVT group than that in the TVAT group（P〈0.05）. Conclusion SXVT for myasthenia gravis is safe and executable. It can alleviate intercostal neuralgia and abnormal chest wall feeling. And it should be considered in the treatment of myasthenia gravis.
