Sténose du pylore chez le nourrisson sous laparoscopie

In 1990, the first laparoscopic pyloromyotomy in a newborn was performed in Limoges (France). Then it spread worldwide. The learning curve is simple because that is a frequent procedure. Prevalence of pyloric stenosis is around 2/1000. The treatment is an extramucosal incision of the tumor according to Ramstedt’s technique. Open access can be a median incision, or a peri-umbilical way; also it can be a laparoscopic approach.From 2004 to 2008, 24 HPS were treated under laparoscopy (4/76 patients in Bicêtre universitary hospital and 20/20 in Boulogne private hospital). Complications were 1 mucosal tear repaired during laparoscopic procedure and 1 navel’s infection (2/24), versus 3 parietal infections and 1 evisceration after open approach in Bicêtre (4/72).Video-surgical method has modified numerous procedures in pediatric surgery. Necessity to prove advantages induces time to validate indications such as hypertrophic pyloric stenosis. Meanwhile these promissing techniques were widely accepted, and many papers recorded laparoscopic pyloromyotomy.Our experience confirms it is a safe surgery, easy to teach and to learn, and complications rate is no higher than by open way.
