摘要Background and objective Because ndical resection for lung cancer invading the initial borderline of different lobes and carina is difficult,we tried to analyse the variables of successful tracheal carinoplasty and bronchovasculoplasty to discover a proper approach for appropriate early and long term results.Methods of 1399 lung resections for primary lung cancer performed in our hospital from April 1985 to December 2006,133 underwent bronchoplastic surgeries, including 15 carinoplasty,cases and 118 sleeve lobectomy(SL)cases,and 118pneumoectomy(PN) cases were compared at the same time.Results Complications occurredin 18 cases, with no operative related mortaliW.For all patients,the l year,3 year,and 5 year survival rateswere 79.8%,56.7%and31.2%,respectively.The 5 year survival rate by cancer stage was 69.2%for Ib,40.6%for IIb,19.6%for IIIa,and 16.6%for IIIa(N2).Conclusion Selection of cases~clearance of lymph nodesJ disposal of the bronchus and pulmonary vessel and replacement or restoration of the superior vena cava are the main factors influencing prognosis.
