Background: Open transumbilical pyloromyotomy (UMBP) and laparoscopic pyloromyotomy (LAP) have been compared on different outcomes, but postoperative pain as a primary end point had never been assessed. The aim of this study was to compare the use of analgesia in UMBP and LAP patients. Methods: Infants with hypertrophic pyloric stenosis treated by UMBP in 2008-2009 were matched with LAP-treated infants. Demographics, type and use of analgesia, and length of stay were recorded. Statistical analysis was performed using the Fisher exact test. Results: Each group contained 19 patients (N = 38) with comparable demographics and no comorbid condition. Bupivacaine was injected intraoperatively in all UMBP and 89% of LAP infants. There was a trend toward increased acetaminophen use in LAP infants (79% vs 58%, P = .61) in the recovery room. There was no difference in opiates use (3 UMBP vs 1 LAP, P = .60). In the ward, more UMBP patients received acetaminophen (78% vs 53%, P = .03). This difference was significant. Mean postoperative length of stay was similar in both groups. Conclusion: Our study suggests that UMBP infants might experience more postoperative pain in the ward, without any impact on various outcomes. A prospective study with a larger sample size should be undertaken to verify these findings.
