There were 74 cases (29.5%) with adhesive and fissureless complications in comparison with all 251 cases who had undergone video-assisted thoracic surgery (VATS) lung operations in author's hospital. On lobectomy and segmentectomy adhesive and fissureless effective factors were old age( p=0.012), the difference between %DLco to %DLco/VA( p<0.05), Brinkman index( p=0.043) compared with non-ad- hesive cases, therefore operation times of fissureless group prolonged (p=0.009). The point at issue was in what manner we should perform appropriate division of the bronchus, the pulmonary arteries and the veins on the fissureless lobectomy. Especially it is very important which the apicoposterior artery( rA2b:Asc) on right upper lobectomy and the lingular segmental artery( lA4+5) on left upper lobectomy branch from the major fissure or not. For that purpose the management procedure had been done pulmonary artery (primary upper division: A1+2+A3)→ pulmonary vein → bronchus → residual pulmonary artery (rA2b or lA4+5). On the very severe fissureless cases the management procedure had been done pulmonary vein → bronchus → pulmonary artery. Mobilization of "fissure first, hilum last" and/or "hilum first, fissure last" techniques should be performed for VATS fissureless lobectomy.
在作者所在医院接受电视辅助胸腔镜手术(VATS)肺手术的251例患者中,有74例(29.5%)出现粘连且无裂隙并发症。在肺叶切除术和肺段切除术中,与无粘连病例相比,粘连且无裂隙的相关影响因素包括老年(p = 0.012)、%DLco与%DLco/VA之间的差异(p < 0.05)、布林克曼指数(p = 0.043),因此无裂隙组的手术时间延长(p = 0.009)。关键问题在于在无裂隙肺叶切除术中应以何种方式对支气管、肺动脉和肺静脉进行恰当的分离。特别是右上肺叶切除术时的尖后段动脉(rA2b:Asc)以及左上肺叶切除术时的舌段动脉(lA4 + 5)是否从主裂隙分支非常重要。为此,处理步骤为肺动脉(上叶前段:A1 + 2 + A3)→肺静脉→支气管→剩余肺动脉(rA2b或lA4 + 5)。对于非常严重的无裂隙病例,处理步骤为肺静脉→支气管→肺动脉。对于VATS无裂隙肺叶切除术,应采用“先裂隙,后肺门”和/或“先肺门,后裂隙”技术进行游离。
