Thoracoscopic Management of Pediatric Patients with Congenital Lung Malformations: Results of a European Multicenter Survey

Background: This study aimed to report a European multi-institutional experience about thoracoscopic management of children with congenital lung malformations. Methods: The records of 102 patients (49 girls and 53 boys) with median age at surgery of 1 year (range 6 months-1.5 years), who underwent thoracoscopic lobectomy in five European Pediatric Surgery units, were retrospectively collected. Indications for surgery included congenital pulmonary airway malformation (CPAM) (n = 47), intra- and extralobar pulmonary sequestration (n = 34), hybrid lesion (CPAM/intralobar sequestration) (n = 2), severe bronchiectasis (n = 9), congenital lobar emphysema (n = 8), and others (n = 2). The condition was asymptomatic in 77/102 (75.5%), whereas symptoms such as recurrent pneumonia and/or respiratory distress were present in 25/102 (24.5%). Results: Surgical procedures included 18 upper, 20 middle, and 64 lower lobe resections. No conversions to open were reported. A 3 mm sealing device and 5 mm stapler were adopted in the last 48/102 patients (47%). The median operative time was 92.2 minutes (range 74-141). The median operative time significantly decreased in patients in whom the vessel division and bronchial sealing were performed using sealing devices (75.5 minutes) compared with suture ligations (118.9 minutes) (P = .001). The median hospital stay was 3.7 days (range 2-6.2). Three/102 patients (2.9%) developed postoperative complications, including air leakage requiring pleural drainage (n = 1) (Clavien IIIb) and respiratory infection (n = 2) (Clavien II). A reoperation was required in one patient with residual pleuropulmonary blastoma (0.9%). All symptomatic patients reported resolution of symptoms postoperatively. Conclusions: Thoracoscopic lobectomy is a safe and effective procedure with excellent cosmetic outcome, in expert hands. Based upon our experience, we strongly recommend surgery in patients with congenital lung malformations by the first year of life, to reduce the risk of infection and make the procedure technically easier, despite the small patients' size. Surgeon's experience and use of miniaturized instruments and sealing devices remain key factors for successful outcome.

Automated summary

This study reports a European multi-institutional experience on the thoracoscopic management of children with congenital lung malformations. Surgical procedures included lobectomies for various indications, with the use of sealing devices and miniaturized instruments playing a key role in successful outcomes.
