肺气肿胸腔镜下肺减容术的临床应用

目的探讨肺气肿的外科处理方法及疗效。方法对15例重度肺气肿的患者进行胸腔镜单、双肺减容术的外科治疗。患者男性12例,女性3例,平均年龄64.3岁。6例行部分肺切除术,1例行部分肺切除术加折叠术,8例行双肺减容术。术中计算机气道内监测CO2变化和顺应性改变,发现呼吸道阻力明显下降和肺顺应性增高,术后2例需呼吸机维持通气分别达7 d和10 d。其余患者呼吸机使用时间为4-62 h,平均26.2 h。术后肺持续漏气时间为3-56 d。平均9.2 d。结果全组患者无死亡,平均住院时间23 d,术后所有患者均获随访。经3、6和12个月分别检查肺功能,各项参数均有逐步好转。FEV1从0.39-0.55恢复至0.82-1.5,FVC从1.17-2.36恢复至2.22-3.1。胸片提示膈肌部分弧度从平面恢复弧形。活动能力从术前平卧和只行走10 m到术后可以步行至600 m以上。结论表明严重肺气肿的患者经胸腔镜下肺减容术后各方面肺功能指示均有明显改善,活动能力逐步好转,均能恢复生活自理。胸腔镜下肺减容术具有创伤小,疼痛轻,恢复快,具有美容和消除患者恐惧心理作用,为多数肺气肿患者所接受。
