Morphological evaluation of reconstructive operations on the bronchi using a microsurgical technic in an experiment

: Morphological study of bronchial anastomoses repair made with or without microsurgical techniques has been performed in 30 mongrel dogs. Comparative analysis of bronchoscopy, microscopy and scanning electronic microscopy data shows earlier epithelialization, more regular conjunction of bronchial tube and less marked inflammation in anastomosis made with microsurgical techniques. The fact may be explained by a less pronounced traumatization of bronchial tissues with microinstruments and also by tight suture of mucosal layer which creates favourable conditions for repair of anastomosis per primam.
