Patient-specific 3D printing for planning complex pediatric chest wall tumor resection and reconstruction in pediatric Ewing sarcoma: A case report
Abstract
Introduction Pediatric chest wall tumors are rare, and their surgical management is challenging, often requiring extensive resection and complex reconstruction. Post-processing techniques such as 3D modeling techniques and 3D printing (3DP) have become increasingly integrated into preoperative surgical planning, particularly in oncologic surgery. Case Presentation A 15-year-old girl with a locoregional Ewing sarcoma involving the left side of the chest wall underwent extensive tumor resection. The tumor evolved from the ninth rib and involved also the adjacent eighth and tenth ribs, parietal pleura and the diaphragm. The lesion was surgically approachable after nine cycles of neoadjuvant chemotherapy with a significant reduction in tumor size (67x65x90 mm vs 22 × 14 mm). Preoperative planning was supported by a life-sized, patient-specific 3D-printed model of the chest wall generated, processing the CT imaging with Bambu Studio v 2.2.2.56 slicing software and printed using a Bambu Lab X1 Carbon 3D printer. The model allowed the surgical team to simulate the planned resection, assess the anticipated chest wall defect, and test the prosthetic reconstruction before surgery. En bloc resection included the eighth, ninth, and tenth ribs, the parietal pleura, and a portion of the diaphragm. Chest wall reconstruction was performed using STRATOS™ titanium bars and a Gore-Tex® mesh. The postoperative course was uneventful. The patient subsequently completed three cycles of adjuvant chemotherapy and received regional radiotherapy based on the pathological findings. Conclusion 3D-printed models may represent a useful adjunct for planning complex pediatric chest wall tumor surgery.
