Video-assisted thoracoscopic lobectomy in infants.

Objective: Congenital lung malformations are often discovered on routine prenatal sonography or postnatal imaging. Lesions such as congenital cystic adenomatoid malformation or pulmonary sequestration may be asymptomatic at birth, and their management is controversial. Thoracoscopy in children has been mainly used for lung biopsy and for the treatment of empyema and recurrent pneumothorax. Very few reports of more technically demanding procedures, such as lobectomy, are currently available. This report evaluates the safety and efficacy of video-assisted thoracoscopic (VATS) lobectomy in infants and small children with asymptomatic prenatally diagnosed lung lesions.

Methods: During 2004, six patients underwent VATS lobectomy without a mini-thoracotomy. Mean age was 10 months (range, 6-19 months). Preoperative diagnosis included congenital cystic adenomatoid malformation (n = 5) and an extralobar pulmonary sequestration. All patients were asymptomatic and surgery was performed electively. Three or four 3-5mm ports were used. Single lung ventilation and controlled low pressure pneumothorax were used in every case. A bipolar sealing device was the preferred mode of vessel ligation and bronchi were closed with interrupted sutures. A chest tube was left in all cases.

Results: All the procedures were completed thoracoscopically. Operating times ranged from 70 to 215 min (mean, 130 min). There were five lower lobe and one middle lobe resections. There were no intraoperative complications and chest tubes were left in place 1-4 days. Two patients showed postoperative hemothorax that stopped spontaneously. Hospital stay ranged from 4 to 9 days (mean, 7 days).

Conclusions: VATS lobectomy in small infants is a feasible and safe technique. Decreased postoperative pain, a shorter hospital stay, and a better cosmetic result are definite advantages of this minimally invasive procedure. Long-term morbidity due to a major thoracotomy incision is avoided.
