[Thoracoscopic lobectomy in patients with congenital cystic adenomatoid malformation].
BACKGROUND
The management of asymptomatic patients with congenital cystic adenomatoid malformation (CCAM) is controversial. This report evaluates the video-assisted thoracoscopic (VAT) lobectomy in children with this malformation, and the different intraoperative complications and their resolution are discussed.


METHODS
Six patients with CCAM underwent video-assisted thoracoscopic lobectomy. All the patients were under one year and all of them were asymptomatic at the diagnosis. The procedures were performed with single lung ventilation and the chest was insufflated with a low flow and pressure to complete collapse of the lung. We used 3 or 4 thoracoscopic ports depending on the difficulty of the dissection. A bipolar sealing device was the preferred mode of vessel ligation and bronchi were closed with interrupted sutures. The following features have been taken into account: age at diagnosis, localization, surgical technique, complications, hospital stay, results, and time of follow-up.


RESULTS
Four lesions were on the right lower lobe (66.7%) and two (33.3%) in the middle lobe. All the procedures were completed thoracoscopically. Chest tubes were left in all cases. Two patients (33.3%) showed postoperative hemothorax but it didn't need blood transfusion. Mean hospital stay was 6 days. At the moment all the patients are asymptomatic with and the mean time of follow-up has been 2 years and 8 months.


CONCLUSIONS
VAT lobectomy avoids the long-term morbidity associated to an open thoracotomy and therefore it is a safe and efficacious technique in asymptomatic children with CCAM. Moreover, a greater number of cases are necessary to validate and to improve the technique.
