A case treated with silicone stent for bronchial granulomatous stenosis caused by anastomosis after right upper sleeve lobectomy was reported. A 68-year-old man complained of atelectasis of right upper lobe due to squamous cell carcinoma was admitted to our department. We performed right upper sleeve lobectomy. Four weeks after the operation, hemoptysis and dyspnea appeared with developing local empyema. We performed closure of pleural fistula and thoracoplasty, however, did not improve the symptoms. We performed tracheotomy for deteriorating dyspnea. In addition, granulomatous stenosis of bronchial anastomotic site was observed endoscopically. We tried to insert silicone stent into stenotic site. Although, first trial was in failure, we modified the design of the stent and succeeded in fixation of the stent. The airway was completely re-opened and good patency had been maintained for 7 months until his death due to pneumonia.
