Bronchoplasties at the Segmental Level.

Although there is insufficient information in the literature on atypical bronchoplasties, these procedures can be performed on centrally located benign or low-grade malignant tumors or advanced lung cancer at the hilum. In particular, sleeve segmentectomy is performed for low-grade malignant tumors and early lung cancer at the hilum; extended sleeve lobectomy is performed for advanced lung cancer at the hilum; and segmental bronchial sleeve resection is performed for benign or low-grade malignancies. These procedures should be performed after strict evaluation of the lymph node status and bronchial margins using intraoperative frozen section analysis.
