Broncholithiasis: Treatment Evaluation in 63 Patients

Abstract

BackgroundBroncholithiasis is a rare disease defined as the presence of calcified material (broncholith) within the tracheobronchial tree. We described our experience in broncholithiasis to provide a more effective clinical basis for the management of this condition. MethodsWe retrospectively reviewed the clinical characteristics, treatments, and outcomes of patients with broncholithiasis at Xiangya Hospital in China from May 2009 to November 2019. ResultsSixty-three patients were enrolled in this study with a median age of 57 years. Cough (57.1%) was the most common symptom of broncholithiasis, followed by hemoptysis (23.8%). Tuberculosis was the most common comorbidity (38%), while 21 patients (30.0%) did not exhibit underlying diseases. Broncholiths within the bronchus led to airway dilation (19.0%), obstructive atelectasis (46.0%), and pneumonia (30.2%). The condition of most patients improved after undergoing endoscopic removal (76.5%) of the broncholiths. The condition of three patients (100%) improved after the surgical removal of the broncholiths. Of the 38 patients (60.3%) who failed to receive removal of broncholiths, 16 received anti-infection treatment, and the other 22 received observation. Most patients (50.0%) who were treated with anti-infectives showed an improvement, whereas the condition of 33.3% of patients who did not receive treatment worsened. ConclusionsBroncholithiasis is a benign bronchial disease that can cause complications. Endoscopic removal of broncholiths is considered as initial therapy and surgical removal is suggested as a second-line treatment. Treatment with anti-infectives is required for patients who fail to receive removal of broncholiths.
