[Extirpation of bronchi: experimental study].
Sixteen dogs were divided to two groups: experimental group (11) and control group (5). In the experimenta group, the arterial blood PO2SaO2, CaO2 and bronchography which were compared between before and after operation were normal and the bronchi position shown by bronchography was not changed and the residual lung afte bronchi extirpation was still in an expansive status. In the control group, segmental resections were performed. Compared with the experimental group, the residual lung tissues after bronchi extirpation only had little wound refection and no ateledasis and expanded well. No destruction was observed in the neighbouring lung tissues. But in the control group, the heavy destruction, consolidation and emphysema were observed in the adjacent normal lung tissues. It is concluced that the extirpation of bronchi can eliminate the residual cavity early after operation and has less destruction and do not destruct the adjacent normal lung tissues.
