Evaluation of the risk factors for postoperative pectus excavatum and scoliosis in cystic lung disease

Purpose To analyze the frequency and predictive factors of the development of postoperative pectus excavatum and scoliosis in children who underwent surgery for cystic lung disease. Methods This study examined patients who underwent surgery for cystic lung disease (open and thoracoscopic) between July 2000 and December 2018 with a > 3-year follow-up period. Lesion size, surgical outcomes, and subsequent musculoskeletal complications were compared between the open surgery and thoracoscopic surgery groups. Univariate and multivariate analyses were performed to identify predictive factors. Results Overall, 90 patients (19 and 71 patients in the open and thoracoscopic groups, respectively) were included in this study. There was no significant difference in the incidence of pectus excavatum or scoliosis between open and thoracoscopic surgery; however, Haller's index and Cobb angle were significantly higher in the open surgery group. In the univariate analysis, neonatal surgery and lesion size were substantial predictors of musculoskeletal malformations. Conclusion Postoperative musculoskeletal deformities emerge after surgical treatment for cystic lung disease, with thoracoscopic surgery showing advantages in selected dimensions. Neonatal surgery and lesion size are pivotal prognostic factors for musculoskeletal complications. Further corroborative multicenter studies are imperative to substantiate these findings and foster enhanced patient outcomes.
