Tracheobronchial sleeve resection in children and adolescents

Abstract

Bronchoplastic techniques preserving lung parenchyma allow resection and reconstruction of the major bronchi and carina and are widely used in adults. The smaller and more delicate airways of children make such operations more demanding, but successful outcome can still be achieved with particular attention to technique. The authors treated 12 patients age 8 to 19 years (mean, 13.8 years) over a 12-year period. Ten patients had tumors of the airway: carcinoid (4), mucoepidermoid (2), malignant fibrous histiocytoma (1), adenocarcinoma (1), granular cell (1), and invasive fibrous tumor (1); and 2 had nonneoplastic strictures. Previous operative treatment included incomplete local excision in 2 and laser ablation in 1. Carinal resection and reconstruction was performed in 6 patients, main-stem bronchial resection in 3, and sleeve lobectomy in 3. There was one death after a complex airway reconstruction for extensive mediastinal fibrosis involving the airway. Postoperative morbidity consisted of prolonged atelectasis in 3 patients. Residual malacia in 1 patient with postpneumonectomy syndrome required further tracheobronchial resection. Follow-up is complete (mean, 64 months; range, 7 to 130). There has been no anastomotic stenosis or tumor recurrence. Preservation of lung function is expected in all patients. In 7 patients, bronchoscopy 4 months to 11 years postoperatively confirmed anastomotic patency and growth. The understanding of bronchoplastic techniques and precise attention to technical detail should allow these procedures to be successfully performed in pediatric patients.
