Laparoscopic pyloromyotomy for hypertrophic pyloric stenosis: a survey of 407 children

Introduction Pyloromyotomy is the standard care for hypertrophic pyloric stenosis. The traditional approach for this procedure is a right upper quadrant transverse incision, although other “open” approaches, such as circumumbilical or periumbilical incision have been described. The more recent approach used is laparoscopic pyloromyotomy (LP), but experience feedback is still debated and its benefits remain unproven. The aim of this study was to make a review of all our LP procedures with an objective evaluation according to the literature.
