Background: Chest tube drainage (CTD) is an indication for the treatment of pneumothorax, hemothroax and is used after a thoracic surgery. But, in the case of incomplete lung expansion, and/or persistent air leak from CTD, medical or surgical thoracoscopy or, if that is unavailable, limited thoracotomy, should be considered. We evaluate the efficacy of bronchoscopic injection of ethanolamine to control the persistent air leak in patients with CTD. Methods: Patients who had persistent or prolonged air leak from CTD were included, consecutively. We directly injected 1.0 mL solution of 5% ethanolamine oleate into a subsegmental or its distal bronchus, where it is a probable air leakage site, 1 to 21 times using an injection needle through a fiberoptic bronchoscope. Results: A total of 15 patients were enrolled; 14 cases of spontaneous pneumothorax [idiopathic 9, chronic obstructive pulmonary disease (COPD) 3, post-tuberculosis 2] and one case of empyema associated with broncho-pleural fistula. Of these, five were patients with persistent air leak from CTD, just after a surgical therapy, wedge resection with plication for blebs or bullae. With an ethanolamine injection therapy, 12 were successful but three (idiopathic, COPD and post-tuberculosis) failed, and were followed by a surgery (2 cases) or pleurodesis (1 case). Some adverse reactions, such as fever, chest pain and increased radiographic opacities occurred transiently, but resolved without any further events. With success, the time from the procedure to discharge was about 3 days (median). Conclusion: Bronchoscopic ethanolamine injection therapy may be partially useful in controlling air leakage, and reducing the hospital stay in patients with persistent air leak from CTD.

연구배경: 중심성 기도폐쇄를 동반하는 진행성 폐암환자에서 기도폐쇄를 호전시키기 위해 다양한 중재적 시술 Tuberculosis and Respiratory Diseases Vol. 64. No. 4, Apr. 2008277방법들이 시도되고 있으며, 이러한 시술방법 중 최근 굴절성 cryoprobe를 이용한 냉동치료가 국내에서도 시도되고 있다. 방법: 냉동치료 기계는 cryomachine과 cryoprobe로 구성되며, 냉매로는 아산화질소(N2O)를 사용하였다. 굴곡경 기관지내시경의 working chanel을 통해 굴절성 cryoprobe를 악성종양의 중심에 위치한 후 급속 냉동($-89^{\circ}C$)하여 악성 종양 조직을 냉동 시킨 후 stalk을 puling하여 제거하거나 급속 냉동과 해동 과정을 반복하였다. 결과: 중심성 기도폐쇄가 발생한 진행성 폐암 환자 4명에게 냉동치료를 시술하였다. 3명의 환자에서 성공적으로 기도폐쇄를 유발하는 종양을 제거하였으며, 그 후 호흡곤란 및 무기폐 소견이 호전되었다. 1명의 환자에서 기관지 천공으로 인한 종격동 기종이 발생하였으며 또 다른 환자에서 냉동치료 도중 대량 출혈이 발생하였으나 응급 조치 후 다시 회복되었다.
