RESUMEN
OBJECTIVE: The authors present a multicenter retrospective series of different benign rib lesions in children operated on using thoracoscopy. MATERIALS AND METHODS: Between 2005 and 2015, 17 rib resections were performed thoracoscopically, in four French departments of pediatric surgery. Of these 17 cases, 13 exostoses, 2 endochondromas, 1 synostosis, and 1 Cyriax's syndrome were noted. Inclusion criteria were benign tumors or rib anomalies such as synostosis, in children younger than the age of 18 years, and thoracoscopy. Open surgery and malignant tumors were excluded. Thoracoscopy was put forward using one optical port as well as one or two operative ports. RESULTS: Ten patients presented with chest pain, dyspnea, or unexplained cough. Six tumors were incidentally diagnosed. One patient presented with a chest wall deformation. Single-lung ventilation was required in 2 cases. In 1 case of endochondroma, a segmental rib resection was performed, leaving a part of the periosteum and the intercostal vessels and nerve. In this case, rib resection was performed using an endoscopic shaver drill system. As for the other cases, a simple resection of the tumor or of the bridge between two ribs (synostosis) was performed. In these cases, a Codman Kerrison laminectomy rongeur was used. There was no complication during or after surgery. Nevertheless, 2 years after surgery, pain did not disappear in 1 case, probably due to a definitive intercostal nerve damage. CONCLUSION: Benign rib lesions in children are rare. Thoracoscopy may be offered to reduce the functional deleterious consequences of an open surgery. It may be put forward especially in case of hereditary multiple exostoses where redo procedures may be required.
