ABSTRACT Objective: Exploration for chronic obstructive pulmonary disease with branched air lumen hamartoma by bronchoscoptic treatment. Material and Method: An old man was referred to our hospital with shortness of breath for many years. Clinical evidence emphysema on respiratory examination, lung function and chest X-ray gave rise to concern. He was diagnosed as COPD and treated with ICS + LABA. But the shortness of breath is still existed. Initial assessment by CT suggested a left lower lobe collapse. Then bronchoscope identified a solid abnormality in main left bronchus. The pathology showed a benign neoplasm. Because of intolerance of operation, the patient was treated by brochoscopic intervention. The endoscopic intervention included resection by electrosurgical snare, electrocautery, argon plasma coagulation (APC). Result: After intervention, the neoplasm was partly removed and the pathological result was endobrochial hematoma. After treatment, the patient’s panting had taken a turn for the better. After one month later, the patient’s lung function improved a lot. Conclusion: In conclusion, endobronchial hamartomas are one of benign neoplasms. It can cause persistent bronchial obstruction and recurrent pneumonias. In this case, invasive endoscopic treatment provides an excellent outcome.
