Laparoscopy in pediatric surgery: Implementation in Canada and supporting evidence

Background/purposeThe purpose of this study was to assess the diffusion of laparoscopy usage in Canadian pediatric centers and the relationship between uptake of laparoscopic surgery and the level of evidence supporting its use.MethodsNational data on four pediatric laparoscopic operations (appendectomy, pyloromyotomy, cholecystectomy, splenectomy) were analyzed using the Canadian Institute for Health Information Discharge Database (2002-2013). The highest level of evidence to support the use of each procedure was identified from Cochrane, Embase, and Pubmed databases. Chi-square test for trend was used to determine significance and time to plateau.ResultsThere were 28,843 operations (open: 12,048; laparoscopic: 16,795). Use of laparoscopic procedures increased over time (p < 0.0001). A plateau was reached for cholecystectomy (2006), splenectomy (2007), and appendectomy (2012), but not for pyloromyotomy. Laparoscopic pyloromyotomy in 2013 remains less diffused than the other procedures (p < 0.0001). Laparoscopic appendectomy and pyloromyotomy are supported by level-1a evidence in children, whereas cholecystectomy and splenectomy are supported by level-1a evidence in adults but level-3 in children.ConclusionsIn Canada, it has taken a long time to reach high-level implementation of laparoscopic surgery in children. Laparoscopic cholecystectomy first reached plateau, whereas laparoscopic pyloromyotomy continues to increase but remains low despite high level of evidence in support of its usage compared to open surgery.
