Congenital lung malformations: a nationwide survey on management aspects by the Italian Society of Pediatric Surgery

Introduction Over the years, congenital lung malformations (CLM) management remains a controversial topic in pediatric thoracic surgery. The Italian Society of Pediatric Surgery performed a national survey to study the current management variability among centers, trying to defne national guidelines and a standardized approach of children with congenital lung malformations. Methods Following a National Society approval, an electronic survey including 35 items on post-natal management was designed, focusing on surgical, anesthesiology, radiology and pneumology aspects. The survey was conducted contacting all pediatric surgical units performing thoracic surgery. Results 39 pediatric surgery units (97.5%) participated in the study. 13 centers (33.3%) were classifed as high-volume (Group A), while 26 centers (66.7%) were low volume (Group B). Variances in diagnostic imaging protocols were observed, with Group A performing fewer CT scans compared to Group B (p=0.012). Surgical indications favored operative approaches for asymptomatic CLM and pulmonary sequestrations in both groups, while a wait-and-see approach was common for congenital lobar emphysema. Surgical timing for asymptomatic CLM difered signifcantly, with most high-volume centers operating on patients younger than 12 months (p=0.02). Thoracoscopy was the preferred approach for asymptomatic CLM in most of centers, while postoperative long-term follow-up was not performed in most of the centers. Conclusion Thoracoscopic approach seems uniform in asymptomatic CLM patients and variable in symptomatic children. Lack of uniformity in surgical timing and preoperative imaging assessment has been identifed as key areas to establish acommon national pattern of care for CLM.
