Pediatric thoracoscopic lung resections: a comprehensive analysis of congenital lesion cases

Background: Congenital lung lesions in pediatric patients may be managed conservatively or by video assisted thoracoscopic surgery (VATS). This study aimed to determine the complications after VATS for congenital lung lesions in children. Methods: All children undergoing a lung resection between January 2009 and June 2022 were retrospectively identified. Children undergoing a primary open lobectomy or a resection other than a congenital lung lesion were excluded. Both early (<30 days) and late postoperative pulmonary complications were determined. The primary endpoint was postoperative complications within 30 days. Results: In total, 56 patients were included, with a median age of 13 months (IQR 9-37). A VATS lobectomy were performed in 46 patients (82%), an extralobar sequestration in 8 patients (14%), an wedge resection in 1 patient and a segment resection in 1 patient. During the COVID pandemic, fewer resections were performed with an increase in symptomatic patients. A conversion to open occurred in 6 patients (11%), of which a preoperative lung infection was associated with an increased risk thereof(p = 0.004). The median follow-up was 22 months (IQR 7-57) and all patients were alive. A postoperative complication (Clavien Dindo ≥3) occurred in 9 patients and complications without the need of intervention in 6 patients. During follow-up a pneumonia occurred in 11 patients. Conclusion: There seems to be a shift towards delayed surgery with an increase in symptomatic congenital lung malformations, which might lead to an increase in postoperative complications.
