Comparison of Tracheal Anastomosis by Interrupted and Continuous Technique of Absorbable polydioxanone (PDS) Suture Material in Rabbit
초록
Background: Tracheal resection and end-to-end anastomosis are the preferred treatment for tracheal tumor or tracheal stenosis. Absorbable suture material has been commonly used in case of tracheal anastomosis. But anastomosis technique is controversial. This experimental study compared between interrupted suture and continuous suture using Polydioxanone (PDS) absorbable suture material after tracheal resection and end-to-end anastomosis in rabbits. Methods : Twenty-four rabbits were used, divided into two groups of 12 animals each. The trachea was resected and then anastomosed with continuous 6-0 polydioxanone (PDS) (group 1), and intermittent 6-0 polydioxanone (PDS) (group 2). The animals were followed up for 6 months. Stenosis of the trachea was assessed at the time of death. Results : In two groups, anteroposterior diameter, transverse diameter, cross sectional area, and perimeter were greater in group 2 than in group 1 but, not significantly different. In addition, histologic findings were not different in two groups. Conclusions : This study suggest that stenosis after tracheal resection and end-to-end anastomosis using absorbable polydioxanone (PDS) suture material be not significantly different in both groups.
