Tracheobronchial resection in humans is a still problem in lung cancer invading the carina, because there is not a standard surgical procedure. This study aimed to compare postoperative complications and histopathological results of simple continuous and simple interrupted suturing techniques in tracheobronchial anastomosis following the wedge carinal resection in dogs. Twelve mongrel dogs were divided into A and B groups. Right pneumonectomy with wedge carinal resection technique was performed under general anesthesia, and then tracheobronchial resection line was sutured simple continuously in group A and simple interruptedly in group B. The dogs were checked during two months in terms of postoperative complications, and euthanized at the end of two months to evaluate tracheobronchial anastomosis lines histopathologically. No postoperative complication was encountered in group A; but, 2 dogs in group B died due to respiratory failure on postoperative 4(th) and 12(th) days. Autopsy of the dogs revealed tracheobronchial dehiscence and opening of the simple interrupted suturing line, which was considered operative technique failure of suturing. Histopathologically, the sections taken from tracheobronchial anastomosis line had similar microscopic results in both group. Statistically, Fisher's exact test was applied between groups to determine the differences with regard to postoperative complications and histopathological results. There was no statistically significant differences between the groups in postoperative complications and histopathological results. In conclusion, operative technique failure of suturing is still common in tracheobronchial anastomosis; however, taking the histopathological results of the study into consideration, it has been implied that both suturing technique can be performed in tracheobronchial anastomosis following the wedge carinal resection.
