Introduction: Our aim is to compare thoracoscopy to thoracotomy in the treatment of congenital lung malformations (CLM) in children.
Materials and methods: We report a retrospective monocentric cohort study. Patients treated at our Center for CLM (1991-2020) were divided in two groups: patients treated with video-assisted thoracoscopic surgery (VATS) and open thoracotomy (OT). Characteristics of the two groups were compared through statistical analysis (GraphPad Prism7). A p value less than .05 was considered statistically significant.
Results: One hundred six patients were included: 58 in VATS group, 48 in OT group. Prenatal diagnosis was possible in 73.6%. The most frequent surgical procedures were lobectomy (43.4%) and sequestrectomy (22.6%). All VATS patients underwent lung exclusion, mostly by endobronchial blocker (69%). Mean operative time was 146.1 min (±52.04 SD) in VATS and 159.2 (±46.53 SD) in OT (p = .1973). Conversion to OT was necessary in 20.6% of VATS patients, but decreased in the last 5 years (6.2%). There were not any intraoperative complication. Respectively in VATS and OT group, length of stay (LOS) was 4.5 days ± 3.6 SD versus 7.7 ± 3.4 SD (p < .0001), chest tube duration 2.8 days ± 3.4 SD versus 3.7 ± 2.4 SD (p < .0001), antibiotic treatment duration 3.7 days ± 4.7 SD versus 5 ± 2.6 SD (p = .1196). Postoperative complications were described in 22.6%. The commonest histological diagnosis (40.6%) was congenital pulmonary airway malformation.
Conclusion: VATS resulted a feasible, effective and safe technique. Operative time and postoperative complications were similar in VATS and OT groups. VATS conversion rate decreased in time. VATS had a statistically significant shorter LOS and chest tube duration.
