Abstract: Changes in the size of anastomosis were experimentally evaluated at oblique (O-group) and right angle (S-group) anastomoses of the bronchus to the lateral wall of the trachea. In addition, the resistance to air current was assessed by the measurement of the intraluminal pressure. 1) Difficulty in right angle anastomosis was assumed from the results of the survival time within 7 days after surgery and high incidence of respiratory failure and anastomosis insufficiency as causes of death. 2) Intratracheal pressure in S group was obviously higher than O-group although intrabronchial pressure did not indicate such a tendency. 3) The shapes and the sizes at anastomoses were also evaluated in accordance with respiratory cycle by the alternate addition of positive and negative pressures. Shortness of the minor axis in S-group was manifest at negative pressure. In addition, the reduction rates in the minor axis of S group were more significant than those of O-group although reduction rates in the major axis were almost similar between the both groups.
