title: [Primary lung cancer protruding into right main bronchus, successfully treated with endoscopic neodymium yttrium aluminum garnet (Nd-YAG) laser].
abstract: Endoscopic neodymium yttrium aluminum garnet (Nd-YAG) laser treatment for endobronchial obstruction originating from the tumor provides a favorable outcome. A 67-year-old male patient with a chief complaint of cough and sputum had a primary lung cancer (squamous cell carcinoma) in the upper lobe of the right lung. The tumor projected into the right main bronchus through the upper lobe bronchus, which completely occluded the lumen of right main bronchus. Middle and lower lobes showed an obstructive pneumonia caused by its obstruction. Firstly, endoscopic Nd-YAG laser treatment for patency of right main bronchus was preoperatively performed with an aim to early improvement of obstructive pneumonia Since the inflammatory findings showed markedly improvement, a right upper sleeve lobectomy could safely be performed. The resected specimen of the tumor in the right upper lobe proved to be a case of complete resection with pathological stage IIIA (T3N1M0). When preoperative lung cancer patient has an obstructive pneumonia causing by the protruding tumor into the central airway, a patency treatment of bronchial airway using endoscopic Nd-YAG laser may lead to decrease a perioperative risk.
