Abstract

Central airway obstruction can result from various benign and malignant conditions, and often requires prompt palliation. The efficacies of a variety of bronchoscopic techniques for the treatment of central airway obstruction such as electrocautery, laser, brachytherapy, argon plasma coagulation and cryotherapy have been established. An insulation-tipped diathermic knife-2 (IT knife-2) was initially introduced for gastrointestinal endoscopic submucosal dissection and has been used globally as a safe and effective instrument. However, its use has not been reported for the treatment of endotracheal or endobronchial lesions. Here, we report the case of central airway obstruction in a 65-year-old male due to malignancy and a 52-year-old-female with post-radiation bronchial stenosis that were treated successfully with the IT-knife-2 via flexible bronchoscopy.

중심성 기도 폐쇄는 양성 혹은 악성 질환과 동반되어 나타날 수 있으며 현재 다양한 기관지경적 치료법이 사용되고 있다. IT knife-2는 소화기 내시경적 시술을 위해 고안된 장비로서 그 안정성과 효용성이 입증되어 국내 의료기관에서 내시경적 점막하 박리술에 널리 사용되고 있다. 저자들은 굴곡성 기관지경과 IT knife-2를 이용하여 진행성 폐암과 방사선 치료 후 발생한 중심성 기도 폐쇄를 가진 두 환자를 성공적으로 치료하였다. 합병증과 예후에 대한 추가적인 연구가 필수적이지만 IT knife-2는 향후 기도 폐쇄의 내시경적 중재적 시술법 중 하나로 고려될 수 있을 것이다.
