经胸骨正中切口双肺肿瘤同期切除术５例，配以经典的单侧后外侧切口肺切除术５例，采用ＰＥＭＳ２．０统计软件包，配对比较了两种术式在下述几方面的差异；（１）两种术式对术后连续７天的ＰＯ２与ＰＣＯ２的影响基本一致，主要表现在术后第二天ＰＯ２的稍微下降，但两组之间的差异在统计学上没有显著性意义：（２）两种术式在手术时间，术后住院天数和生活质量等方面也不存在显著性差异。这些结果提示，病人能很好耐受双侧肺同期部分切除术。接受这一术式之后还可再次安全地接受第二次肺手术。本研究组的中位生存期已超过１２个月，生存期最长的已超过３年。因此，无论从治疗效果还是从经济角度来看，在治疗双肺多发转移癌上，经胸骨正中切口双肺肿瘤同期切除术值得倡导与推广。
Two patients underwent simultaneous thoracic bone-assisted double lung tumor resection in 5 cases, combined with classic unilateral posterolateral incision pneumonectomy in 5 cases. The PEMS2.0 statistical software package was used to compare the differences between the two methods in the following aspects; (1) The effects of the two methods on PO2 and PCO2 after 7 consecutive days were basically the same. The PO2 showed a slight decrease on the second postoperative day, but the difference between the two groups was not statistically significant. : (2) There were no significant differences between the two operations in terms of operation time, postoperative days of hospitalization and quality of life. These results suggest that the patient is well tolerated by bilateral partial simultaneous lung resection. After receiving this procedure, you can safely receive the second lung surgery again. The median survival of this study group has exceeded 12 months, and the longest survival period has exceeded 3 years. Therefore, both from the therapeutic effect and from the economic point of view, in the treatment of multiple lung metastasis of multiple metastases, trans-sternotomy double lung tumor simultaneous resection is worthy of promotion and promotion.
