RESUMO
BACKGROUND AND OBJECTIVES: Enhanced recovery after surgery (ERAS) pathways are associated with better postoperative recovery; however, evidence is lacking in liver cancer surgery. This study aimed to evaluate the impact of an ERAS pathway in US veterans undergoing liver cancer surgery. METHODS: We initiated an ERAS pathway for liver cancer surgery with preoperative, intraoperative, and postoperative interventions, which included a novel regional anesthesia technique, erector spinae plane block, for multimodal analgesia management. A retrospective quality improvement study was conducted with patients undergoing elective open hepatectomy or microwave ablation of liver tumors before and after ERAS pathway implementation. RESULTS: With 24 patients in the post-ERAS group and 23 patients in the pre-ERAS group, we found a significant decreased length of stay in the ERAS group (4.1 days ± 3.9) compared with traditional care (8.6 days ± 7.1, P = .01) and decreased perioperative opioid consumption including intraoperative opioids (post-ERAS 49.8 mg ± 28.5 vs pre-ERAS 98 mg ± 42.3, P = 4.1E-5), postoperative opioids (post-ERAS 65.3 mg ± 59.9 vs pre-ERAS 175.7 mg ± 210.6, P = .018), and patient-controlled analgesia requirements (post-ERAS 0% vs pre-ERAS 50%, P < .001). CONCLUSION: The implementation of ERAS for liver cancer surgery in our veteran population translates into decreased length of stay and perioperative opioid consumption. Although this study is limited as a quality improvement project implemented at one institution with a small sample size, our results are clinically and statistically significant and sufficient to warrant further investigation into the efficacy of ERAS as the surgical needs of the US veteran population increase.
