傳統上，使用胸腔鏡做雙側肺腫瘤切除手術，需要切開六個傷口，並於術中換位，而我們這位病人，經由劍突下切開一個傷口而完成手術，不僅不需換位，也可縮短手術時間，術後疼痛較少，在傷口的美觀上也比較理想。然而，在手術當中，外科醫師切下右肺腫瘤後，於單肺通氣下進行左邊肺腫瘤切除時，病人發生右側張力性氣胸，血氧下降，在停止灌二氧化碳到胸腔以後情況改善。我們回顧相關文獻，並且探討未來進行類似的手術時的處置流程與注意事項。

Traditionally, up to six incisions are required for video-assisted thoracoscopic surgery (VATS) for bilateral lung tumor resection. Besides, change posture was required during operation. In this case report, a single-incision subxiphoid approach was used for VATS to shorten operation time and reduce postoperative pain; this approach may also lead to better cosmetic results. However, in the described case, after a right-side tumor was removed, an episode of desaturation due to right-side tension pneumothorax was observed during one-lung ventilation for left lung tumor resection. CO2 insufflation was ceased, and the patient’s condition improved. A literature review and suggestions for future similar surgeries are discussed.
