Abstract

In patients undergoing surgery for primary lung cancer in Japan, the proportion of those receiving bronchoplasty is reportedly 1.7%. In this article, we report a relatively rare technique, flap bronchoplasty. The patient was an 11-year-old girl. A tumorous lesion was detected on investigating repeated pneumonia, occupying the bronchus intermedius. Initially, a diagnosis of benign papilloma was made based on bronchoscopy-guided biopsy findings. Rigid bronchoscope-guided core-out tumorectomy was performed. Finally, pathological findings suggested a low-grade mucoepidermoid carcinoma. Bronchoscopy revealed residual tumor cells at the tumor base on the B6 side of the bifurcation between the B6 area and bronchus basalis. Based on these findings, additional resection was considered necessary. S6 segmentectomy with wedge resection of the bifurcation between the B6 area and bronchus basalis was performed. Reconstruction with a B6 bronchial flap for an inferior-lobe bronchial defect was conducted. Due to ①the tumor base being located on the bifurcation between the B6 area and bronchus basalis, and ②preopearative pathological findings suggesting a low-grade mucoepidermoid carcinoma, reconstruction with a B6 bronchial flap (S6 segmentectomy) was performed as limited surgery.
