According to the Annual report of the Japanese Association for Thoracic Surgery, 649 tracheal or bronchial resections with or without lung resection were performed in Japan in 2014. Of those, only 13 patients (2%) underwent bronchial resection and reconstruction without lung parenchymal resection. In the present study, we reviewed five cases of endobronchial tumor treated by bronchial resection and reconstruction without lung parenchymal resection from 1994 to 2015 in our institution. The histologic types of endobronchial tumor were as follows: 3 typical carcinoids, 1 lipoma, and 1 squamous cell carcinoma. Regarding locations of the tumors, 2 tumors were in the right intermediate bronchus, 2 in the left main bronchus, and 1 in the left lower bronchus. Three tumors were resected with posterolateral thoracotomies and 2 tumors were resected with clamshell incision. The mean operative time was 335±104 minutes. The mean total blood loss was 301±372 mL. The mean duration of chest drainage was 7.0±3.7 days. The period of hospital stay after surgery was 23.8±10.5 days. Postoperative complications were observed in 2 patients: one had respiratory failure that required temporary mechanical ventilation, and the other had anastomotic stenosis that was treated by single balloon dilation. All patients are currently alive without recurrence. The findings suggest that bronchial resection and reconstruction without parenchymal resection is a useful option for endobronchial benign or low-grade malignant tumors to preserve the lung function.
