title: Large paraesophageal hernias in children. Early experience with laparoscopic repair.
abstract: BACKGROUND
  Large paraesophageal hernias (LPEH) in children are unusual. The aim of this study is to report the management of LPEH and our initial experience with the laparoscopic approach.
  
  
  METHODS
  Since September 2005, four children aged 4-17 years underwent laparoscopic repair of LPEH at the Children's Hospital of Eastern Ontario. Three children had previous fundoplications and two of these had a gastrostomy. Closure of the hiatal defect included crural sutures and prosthetic material, either polytetrafluoroethylene-polypropylene mesh or porcine small intestinal submucosal patch. The charts were retrospectively analyzed.
  
  
  RESULTS
  The operative time was 300-540 minutes, with one conversion and two mediastinal pleural tears. Postoperative chest X-ray showed neither mediastinal nor intrapleural air. The median hospital stay was 3 days. Contrast X-ray showed no recurrent hernia and an intact fundoplication.
  
  
  CONCLUSIONS
  LPEH in children is usually a complication of previous fundoplication. Laparoscopic repair is technically demanding but feasible. Adequate crural repair using mesh may reduce the incidence of recurrence. In view of the rarity of LPEH in children, a combined multicenter study is needed to evaluate the results of laparoscopic repair.
