Open Versus Laparoscopic Pyloromyotomy for Pyloric Stenosis—A Systematic Review and Meta-Analysis

•Low certainty of evidence suggests that laparoscopic pyloromyotomy may lead to higher rates of incomplete pyloromyotomy and mucosal perforation.•With regard to efficiency outcomes (operation time, time to full feeds, etc.), no conclusion can be drawn due to very low quality of evidence.•Included RCTs are outdated. More and newer RCTs are needed to answer the question if open or laparoscopic pyloromyotomy is preferable.
