Popis: Background. This study was aimed to determine the resistance to pressure of manual and stapled bronchial closures under ideal conditions (90° to the bronchial tree) and parallel to the trachea (45°). Material and methods. An experimental study was done on 60 explanted pig tracheae which were alternatively closed with either double-layer, running sutures angled 90o to the cartilaginous rings or an automatic stapling device. The closure line was placed exactly 90° to the bronchial tree in 30 cases and parallel to the trachea (45°) in 30. The sutures were placed under pressure until air leakage was observed. The leakage pressure was digitally recorded. Results. A statistically significant difference existed between the two groups. Mechanical sutures proved more resistant to pressure (P=0.011). Conclusions. Under ideal conditions, the resistance to pressure of mechanical sutures is equal to if not better than that of manual sutures.
