PurposeThe aim of the study was to determine whether laparoscopic pyloromyotomy (LP) or open pyloromyotomy (OP) is the most effective intervention in infants with hypertrophic pyloric stenosis.MethodsA systematic review of the published literature was undertaken in February 2009. Prospective studies comparing LP and OP were selected. Age, weight, complications, duration of operation, time to full feedings, postoperative vomiting, and postoperative length of stay (LOS) data were extracted.ResultsSix prospective studies (5 level I, 1 level II) with 625 (303 LP, 322 OP) participants met selection criteria. Combined estimates indicated that LP had a lower total complication rate (odds ratio [OR], 0.58 [0.35, 0.97]; P = .04), mostly due to a lower wound complication rate (OR, 0.42 for LP [0.20, 0.91]; P = .03). Patients who underwent LP also had shorter time to full feedings (mean difference [MD], −11.52 hours [−12.77, −10.27]; P < .00001) and shorter postoperative LOS (MD, −5.71 hours [−8.90, −2.52]; P = .0005). No statistically significant differences were noted in the rates of mucosal perforation, wound infection, postoperative emesis, or operating time. Incomplete pyloromyotomy occurred in 6 patients who underwent LP (OR, 7.74 [0.94, 63.38]; P = .06).ConclusionsThis meta-analysis favors the laparoscopic approach with significantly reduced rate of total complications, which is mostly due to a lower wound complication rate.
