Comparison of thoracoscopy vs. thoracotomy on musculoskeletal outcomes of children with congenital pulmonary airway malformation (CPAM)

Abstract

Background: It has been postulated that video-assisted thoracoscopic surgery (VATS) is superior than conventional thoracotomy for resection of congenital pulmonary airway malformation (CPAM) in terms of shorter hospital length of stay, reduced post-operative complication and better long-term pulmonary outcome. However, there is limited available data concerning the effect of VATS and conventional thoracotomy on musculoskeletal aspects in patients with CPAM. This study aims to compare the long-term effects of both surgical techniques on musculoskeletal outcomes in this group of patients.Methods: Thirty-five patients with mean age of 11.38 years old who underwent VATS or conventional thoracotomy for CPAM resection were recruited in this study. The mean follow-up time was 10.42 years (5.48 to 17.71 years). Musculoskeletal examination included screening of musculoskeletal deformities (elevation of shoulder, asymmetry of nipple level, breast/ pectoral muscle maldevelopment, winging of scapula, scoliosis), measurement of bilateral chest wall in relation to anatomical parameter, and testing of shoulder range of motion and power.Results: The prevalence of winged scapula was significantly lower in patients who underwent VATS than thoracotomy (13% vs 58%, p = 0.008). There is also a smaller reduction in operated-side chest wall vertical distance in VATS patients (0.982 vs 0.956, p = 0.058). There were no significant difference in prevalence of other musculoskeletal deformities, other chest wall measurements, shoulder range of motion and power between two groups.Conclusion: Thoracoscopy decreases the incidence of scapular winging but has no effect on effect on other musculoskeletal deformities.
