Chest Wall Reconstruction in Pediatric Patients with Chest Wall Tumors: A Systematic Review

Background: Resection of pediatric chest wall tumors can result in large defects requiring reconstruction for function and cosmesis. Multiple reconstructive methods have been described. We performed a systematic review of the literature to describe commonly used approaches and outcomes.Methods: A systematic literature search was performed for English-language publications describing chest wall tumor resection and reconstruction using implantable materials in patients & LE;21 years, excluding soft tissue resection only, sternal resection, and reconstruction by primary repair or muscle flaps alone. Data were collected on diagnoses, reconstructive method, and outcomes. Rigid chest wall reconstruction was compared to mesh reconstruction. Results: There were 55 articles with 188 patients included. The median age was 12 years. Most tumors were malignant (n = 172, 91.5%), most commonly Ewing's sarcoma (n = 65, 34.6%), followed by unspecified sarcomas (n = 34, 18.1%), Askin's tumor (n = 16, 8.5%; a subset of Ewing's sarcoma) and osteosarcoma (n = 16, 8.5%). A median of 3 ribs were resected (range 1-12). Non-rigid meshes were most common (n = 138, 73.4%), followed by rigid prostheses (n = 50, 26.6%). There were 19 post-operative complications (16.8%) and 22.2% of patients developed scoliosis. There were no significant differences in complications (20.5% rigid vs. 10.6% non-rigid, p = 0.18) or scoliosis (22.7% vs. 14.0%, p = 0.23) by reconstruction method, but complications after rigid reconstruction were more likely to require surgery (90.0% vs. 53.9%, p = 0.09). The median follow-up duration was 24 months.Conclusions: In this review of the literature, there were no significant differences in overall post-operative complications or scoliosis development by reconstruction method, yet complications after rigid reconstruction were more likely to require surgical intervention.
