Bronchial sleeve resections: lung function resurrecting procedure

Abstract

Objective: Mainstem bronchus obstruction results in lung function exclusion. The aim of this study was to revisit lung function restoration obtained by different types of bronchial sleeve resections in selected patients with endobronchial tumors.

Methods: Eleven patients (9 women and 2 men, mean age 47 years) presented with endobronchial tumors and ipsilateral lung function exclusion. Mainstem bronchial sleeve resection was performed in 7 patients, right bilobar and mainstem bronchial sleeve resection in 2, and left upper sleeve lobectomy in 2. Tumors consisted in 8 bronchial carcinoids, 2 adenoid cystic carcinomas, and one inflammatory myofibroblastic tumor. Fiberoptic bronchoscopy and quantitative ventilation-perfusion lung scan were performed in all patients at work-up to assess lung function exclusion and during the first year following bronchoplastic procedure to study recovery. Long-term follow-up consisted of physical examination, thoracic computed tomographic scan and bronchoscopy every year.

Results: There was no postoperative death. The long-term follow-up was complete and ranged from 12 to 192 months (median: 102.7 months). The lung function was completely restored in all patients. The ventilation function was immediate, but the perfusion was restored in a mean interval of 8.2 months (ranging from 3 to 12 months). All patients are currently alive, and no local tumor recurrence was observed.

Conclusions: Some obstructing tumors may be removed by various types of bronchial sleeve resections that permit lung function restoration and long-term local control of the disease. However, at least one year is required for lung perfusion to completely recover, despite immediate ventilation restoration.
