With an experience of 61 major videothoracoscopic pulmonary resections (MVPR) consisting of 58 lobectomies and 3 pneumonectomies, the authors discuss major technical problems, causes of conversion, indications and limits of MVPR. Technical difficulties (pleural adhesions, perihilar lymphnodes or fibrosis, absence of fissures), videoendoscopic control of vascular lesions and problems of bronchial suturing are discussed.
