Introduction: Thoracoscopic repair of congenital diaphragmatic hernia (CDH) has been described, but its efficacy and safety have not been validated. The aim was to compare our experience of thoracoscopy with laparotomy repair. Methods: After ethics approval, we reviewed the notes of neonates with CDH operated in our institution between 2003 and 2008. Two historical groups were compared: infants who underwent laparotomy (2003-2008) or thoracoscopy (2007-2008). Data were compared by t test or Mann-Whitney tests. Results: Thirty-five children had open repair of CDH, and 13 had thoracoscopic repair. Groups were homogeneous for age and weight. Five (38%) neonates who had thoracoscopy were converted to open for surgical difficulties (n = 4) and O2desaturation (n = 1). Patch repair was used in 12 (34%) open and 6 (46%) thoracoscopic repairs. End-tidal CO2was significantly elevated during thoracoscopy, but this was not reflected in arterial CO2or pH. There were 3 (8%) recurrences after open repair and 2 (25%) after thoracoscopy (P = .19). Conclusion: Thoracoscopic repair of CDH is feasible. Arterial blood gases should be closely monitored. Despite higher EtCO2, conversion to open was mainly because of difficult repair. A randomized trial is necessary to assess the effect of thoracoscopy on ventilation and recurrences. © 2010 Elsevier Inc. All rights reserved.
