Abstract:Objective To explore the effect, safety and feasibility of rigid bronchoscope combined with flexible bronchoscope in the treatment of benign airway tumors.Methods From December 2018 to October 2019, 12 cases of benign tumor of the airway were analyzed retrospectively. The changes of clinical manifestations, airway diameter, shortness of breath index and FEV1 were observed before and after treatment. The imaging, microscopic manifestations and pathology of different types of benign tumor of the airway were analyzed.Results After treatment with rigid bronchoscope combined with flexible bronchoscope, the clinical manifestations of 12 patients were significantly improved. There were significant differences in airway diameter and FEV1 before and after treatment, and the shortness of breath index was significantly improved. During the treatment, one patient had more bleeding, about 30 mL, improved after balloon compression, and no patient died.Conclusion Rigid bronchoscopy combined with flexible bronchoscopy is an effective and safe method in the treatment of benign airway tumors, which can quickly remove tumor tissues, relieve airway stenosis and improve the clinical symptoms of patients.
