title: [Thoracoscopic lobectomy (non rib-spreading method): versus a video assisted lobectomy and a conventional thoracotomy].
abstract: We analyzed 33 thoracoscopic lobectomy (non rib-spreading method: NR) cases and 33 video assisted lobectomy (VA) cases and 49 posterolateral thoracotomy (PL) cases, regarding post-operative changes in the serum enzyme levels, operative bleeding, required analgesic treatments, changes in the respiratory function and other factors. Regarding the post/pre-operative ratio of creatinin phosphokinase, bleeding and analgesic treatment NR was showed significantly lower levels than the other two methods. Regarding the post/pre-operative ratio of vital capacity of the lung NR was significantly less than PL for every six months after the operation. With NR the mean number of dissected mediastinal nodes was 14.2 +/- 7.4 which was not significantly different from VA and PL. We thus concluded that NR caused less thoracotomic damage and especially far less restrictive damage to the respiratory function than both PL and VA. NR may also result in a better quality of life than VA and PL. The node dissection required for NR is also not considered to be inferior to that for PL because the number of dissected nodes for NR was not significantly different from that for PL. Therefore, in cases presenting with clinical stage I primary lung cancer NR is thus considered to be indicated in order to obtain an improved post-operative quality of life.
