Obstructive endobronchial tumours often cause decreased quality of life. Bronchial ethanol injection (BEI) therapy is considered an effective modality for airway dilatation or haemoptysis without specialist equipment. Here, we report experiences of two cases in which BEI therapy was effective for obstructive endobronchial tumours. In Case 1 with adenoid cystic carcinoma of the lung, BEI therapy and balloon dilatation were performed as treatment for the left main bronchus restenosis after metallic stent insertion. In Case 2 with squamous cell carcinoma of the lung, BEI therapy was performed after radiation therapy to the lesion that recurred in the entrance of the superior segment of the right lower lobe. Tumour progression was controlled with multiple BEI therapy. We consider BEI therapy useful because this procedure is easy to conduct, has low cost and can be done under particular conditions including post-tracheobronchial stent placement and post-radiation.
阻塞性支气管肿瘤常导致生活质量下降。支气管乙醇注射（BEI）疗法被认为是一种无需专业设备即可实现气道扩张或治疗咯血的有效方式。在此，我们报告两例BEI疗法对阻塞性支气管肿瘤有效的病例。病例1为肺腺样囊性癌，BEI疗法和球囊扩张术用于治疗金属支架置入后左主支气管再狭窄。病例2为肺鳞状细胞癌，对右下叶上段入口处复发的病灶进行放射治疗后实施BEI疗法。通过多次BEI疗法控制了肿瘤进展。我们认为BEI疗法有用，因为该操作简便、成本低，且可在包括气管支气管支架置入术后和放疗后等特定情况下进行。
