Basic interrupted versus continuous suturing techniques in bronchial anastomosis following sleeve lobectomy in dogs.
OBJECTIVE
Sleeve resection with or without lung resection is a valid conservative operation for patients with benign or malignant tumors; it enables the preservation of lung parenchyma. The aim of this prospective randomized study was to compare complications, operating time, and bronchial healing between the techniques of interrupted and continuous suturing for bronchial anastomosis in dogs.


METHODS
Twenty adult mongrel dogs each weighing 18-22 kg (average: 20 kg) were divided into two groups according to the anastomosis technique performed: group A, interrupted suturing and group B, continuous suturing. Each group comprised of 10 dogs. Following right thoracotomy, sleeve resection of the right cranial lobe was performed in all dogs. Basic interrupted sutures using 4/0 Vicryl (Ethicon, USA) were used in group A, and continuous sutures were used in group B.


RESULTS
The median anastomosis time was 15.2 min (range: 13-21 min) in group A and 9.6 min (range: 8-13 min) in group B. In all dogs, the anastomosis line was resected via right pneumonectomy for histopathological investigation 1 month after sleeve resection. Histopathological examination revealed that the healing of the anastomosis was not affected by the suturing technique applied. One dog from each group died on the fourth postoperative day; Fisher's exact test, p=0.763.


CONCLUSIONS
Our research revealed that the healing of the anastomosis was not affected by the suturing technique performed.
