Laparoscopic versus open pyloromyotomy in infants: a systematic review and meta-analysis.

Purpose: To determine whether open or laparoscopic pyloromyotomy is superior for the treatment of hypertrophic pyloric stenosis in infants.

Methods: We searched MEDLINE, EMBASE, and CENTRAL for articles comparing laparoscopic and open procedures. We conducted meta-analyses when possible and described other results narratively.
