Purpose: Congenital lung malformations (CLM) predispose patients to recurrent respiratory tract infections and pose a rare risk of malignant transformation. Although pulmonary lobectomy is the most common treatment of a CLM, some advocate segmental resection as a lung preservation strategy. Our study evaluated lung-preserving thoracoscopic segmentectomy as an alternative to lobectomy for CLM resection.
Methods: We conducted a retrospective review of patients who underwent thoracoscopic segmentectomy for CLM from 2007 to 2010.
Results: Fifteen patients underwent thoracoscopic segmentectomy for CLM. There were five postoperative complications: three asymptomatic pneumothoraces and a small air leak that resolved without intervention. One patient developed a bronchopulmonary fistula requiring thoracoscopic repair. At follow-up, all patients are asymptomatic. One patient has a small amount of residual disease on postoperative computed tomography (CT), and re-resection has been recommended.
Conclusions: Thoracoscopic segmentectomy for CLM is a safe and effective means of lung parenchymal preservation. The approach spares larger airway anatomy and has a complication rate that is comparable with that of thoracoscopic lobectomy. Residual disease can often only be appreciated on postoperative CT scan and may require long-term follow-up or reoperation in rare cases. This lung preservation technique is best suited to smaller lesions.
