Endoscopically Applied Biodegradable Stent in a Rabbit Model of Pediatric Tracheomalacia

This is the authors' abstract. We don't add key points for this paper.

We successfully developed a PDO stent and an endoscopic guide placement system. The degradation time of the stent was around 10 weeks in normal rabbits, and its degradation was accelerated in the tracheomalacia model. The mucosal changes associated with PDO stent placement were reversible. Placement of the PDO stent prolonged survival in tracheomalacia-model rabbits.
