Objective To investigate the clinical value of subxiphoid incision thoracoscopic treatment for bilateral bullous lung disease in one-stage operation . Methods We selected 30 patients with bilateral bullous lung disease treated by single hole thoracoscopic surgery at the same period in our hospital from January 2014 to January 2016.An incision under the xiphoid was made . The thoracoscope was put into the pleural cavity through the single hole where had more serious lesions .The pulmonary bulla with basal diameter <0.5 cm was cauterized directly; the bulla with basal diameter 0.5 -2 cm was clipped and closed with Hem-o-lok or removed after ligation;the patchy bulla with basal diameter >2 cm was given Endo-GIA resection.After one side of the surgery was completed, the same method was used to complete the contralateral surgery . Results The amount of bleeding during the operation was (53.1 ±17.6) ml, the operation time was (105.6 ±20.3) min, the postoperative time of chest tube was (6.3 ±2.5) d, and the time of postoperative hospital stay was (8.9 ±2.6) d.After the operation, pulmonary air leakage occurred in 2 cases, which was cured after chest irrigation .All the patients were followed up for 3-12 months, with an average of 7.6 months.No recurrence was found. Conclusion The subxiphoid incision thoracoscopic treatment for bilateral bullous lung disease in one -stage operation is safe and reliable .%目的探讨经剑突下切口胸腔镜同期治疗双侧肺大疱的临床价值。方法2014年1月～2016年1月我院对30例双侧肺大疱采用单孔胸腔镜同期手术，剑突下4 cm切口作为单孔，将胸腔镜置入病变较重侧胸腔后，寻找到肺大疱，对基底直径＜0．5 cm 大疱直接电棒烧灼；基底直径0．5～2 cm大疱Hem-o-lok夹闭或切除后缝扎处理；基底直径＞2 cm的片状肺大疱用Endo-GIA切除。一侧手术完成后，再经单孔将胸腔镜置入对侧胸腔，同法完成对侧手术。结果术中出血量（53．1±17．6）ml，手术时间（105．6±20．3）min，术后胸管留置时间（6．3±2．5）d，术后住院时间（8．9±2．6）d。术后肺漏气2例，经胸腔冲洗后治愈。30例术后随访3～12个月，平均7．6月，均无复发。结论经剑突下切口单孔胸腔镜同期手术治疗双侧肺大疱安全、可靠。
