Background: Pathways of Enhanced Recovery in Liver Surgery (ERILS) decrease inpatient opioid use, however, there is little existing data regarding their effect on discharge prescriptions and post-discharge opioid intake. Methods: For consecutive patients undergoing liver resection from 2011-2018, clinicopathologic factors were compared between patients exposed to ERILS and traditional pathways. Multivariable analysis was used to determine factors predictive for traditional opioid use at the first postoperative follow-up. The ERILS protocol included opioid-sparing analgesia, goal-directed fluid therapy, early postoperative feeding, and early ambulation. Results: Of 244 cases, 147 ERILS patients were compared to 97 traditional pathway patients. ERILS patients were older (median 57 vs. 52 years, p=0.031) and more frequently had minimally invasive operations (37% vs. 16%, p<0.001), with fewer major complications (2% vs. 9%, p=0.011). ERILS patients were less likely to be discharged with a prescription for traditional opioids (26% vs. 79%, p<0.001) and less likely to require opioids at their first postoperative visit (19% vs. 61%, p<0.001) despite similarly low, patient-reported pain scores (median 2/10 both groups, p=0.500). On multivariable analysis, traditional recovery pathway were associated with traditional opioid use at first follow-up (OR 6.4, 95% CI 3.5-12.1; p<0.001). Conclusions: The implementation of an ERILS pathway with opioid-sparing techniques was associated with decreased postoperative discharge prescriptions for opioids and outpatient opioid use after oncologic liver surgery, while achieving the same level of pain control.
