The association of sex with pain scores and perioperative opioid administration following laparoscopic sleeve gastrectomy

Aim: We investigated whether sex is associated with pain scores and opioid administration after laparoscopic sleeve gastrectomy. Materials & methods: We performed a single-center, retrospective analysis of laparoscopic sleeve gastrectomy patients from December 2016-July 2018. Multivariable linear regressions were performed to investigate the association of sex with pain scores and opioid administration. Results: Baseline pain scores were similar between women and men (n = 266; 78% women). Men reported lower pain scores in all phases of care and received more opioids during their hospitalization (B = 25.48; 95% CI: 5.77-45.20; p = 0.01), compared with women. Conclusion: Our data suggest that women self-report greater postoperative pain scores, while men received more opioids during their hospitalization. Further studies are needed to understand the reasons for such differences in postoperative pain management. Lay abstract: Men are at higher risk for long-term opioid use compared with women, but it remains unclear whether perioperative management is a sentinel event for such outcomes. Since patients who receive higher amounts of postoperative opioids are more likely to remain on long term narcotics, we investigated whether sex is associated with pain scores and opioid administration after bariatric surgery. We demonstrate that men self-report lower pain scores in the postanesthesia care unit, surgical floor and at discharge, compared with women. We also show that while men and women received comparable doses of opioids in the operating room and postanesthesia care unit, men received more opioids on the surgical floor. Our findings suggest that strategies to reduce opioid administration after bariatric surgery should largely focus on care after the immediate postoperative period.
