To evaluate the effectiveness of surgical sealant (CoSeal) in sealing the tracheal assess sites after transtracheal thoracoscopy.
Two dogs underwent transtracheal thoracic exploration and pericardial window creation. The thoracic cavity was approached with flexible bronchoscope through a 9-mm tracheal incision. The pericardial window was performed with a needle knife via the working channel of the bronchoscope, and the tracheal assess site was closed with CoSeal using a rubber catheter. The integrity of tracheal healing was evaluated under positive pressure ventilation.
Transtracheal creation of pericardial window and closure of tracheal incision with CoSeal was successfully performed in both dogs. There was no evidence of air leaks from the chest tube during positive pressure ventilation. Autopsy revealed no injury to the mediastinum and intrathoracic structure.
Endoscopic closure of tracheal access site of NOTES with CoSeal appears to be a feasible technique.
评估手术密封剂（CoSeal）在经气管胸腔镜检查后封闭气管穿刺部位的有效性。
两只犬接受经气管胸腔探查和心包开窗术。通过一个9毫米的气管切口，用可弯曲支气管镜进入胸腔。经支气管镜工作通道用针刀进行心包开窗术，并用橡胶导管将CoSeal用于封闭气管穿刺部位。在正压通气下评估气管愈合的完整性。
两只犬均成功进行了经气管心包开窗术并用CoSeal封闭气管切口。正压通气期间胸腔引流管没有漏气迹象。尸检显示纵隔和胸内结构无损伤。
用CoSeal对NOTES气管穿刺部位进行内镜封闭似乎是一种可行的技术。
