Lower tracheal and endobronchial lesions represent a difficult management problem. While there has been some success in the treatment of these lesions with the carbon dioxide laser, the limitations of its delivery system have restricted its use in infants and neonates. The potassium titanyl phosphate (KTP) laser, transmitted via a flexible quartz fiber, can be precisely manipulated even through rigid pediatric bronchoscopes as small as 3.0 mm. In addition, the Hopkins telescopic lens may be used to improve visualization and control. We report our experience using the KTP laser to treat 15 pediatric patients with tracheal and endobronchial lesions. The nature of the lesions, the details of the technique, and the results are presented.
气管下段和支气管内病变的处理颇具难度。尽管二氧化碳激光在治疗这些病变方面取得了一些成效，但其传输系统的局限性限制了它在婴儿和新生儿中的应用。磷酸钛氧钾（KTP）激光通过柔性石英纤维传输，即使通过小至3.0毫米的硬质儿科支气管镜也能精确操控。此外，可使用Hopkins望远镜式透镜来改善视野和操控性。我们报告了使用KTP激光治疗15例患有气管和支气管内病变儿科患者的经验。介绍了病变的性质、技术细节及结果。
