[A comparative analysis of bronchus stump closure methods after pneumonectomy]

Original method of bronchus stump closure after pneumonectomy is presented. Developed compression bronchial suture was compared with manual Sweet suture and mechanical sutures in the experiment with 36 non-pedigreed dogs. Efficacy of different methods was evaluated basing on the clinical findings, radial, endoscopic and morphological observations. Macro- and microscopic investigations signify about the healing of main bronchus stump by primary intention with bronchial epithelium repair in the stump fundus under conditions of compression suture in 30 days after operation. It is ascertained that compression suture creates optimal conditions for stump repair compared with traditional manual and mechanical sutures healing by secondary intention.
