Abstract

Background: Enhanced recovery after surgery (ERAS) protocols are now commonplace in many fields of surgery, but only limited data exists for their use in hepatobiliary surgery. We implemented standardized ERAS protocols for all open hepatectomies and replaced thoracic epidurals with a transversus abdominis plane (TAP) block.

Methods: We performed a retrospective cohort study of all patients undergoing open hepatectomy during the 14 months before and 19 months after implementation of an ERAS protocol at our institution (January 2014-September 2016). Trained abstractors reviewed charts for patient demographics, perioperative details, and healthcare utilization. All nursing-reported visual analog scale pain scores were sampled to identify patients with uncontrolled pain (daily mean score > 5). Outcomes included length of stay (LOS), costs, and 30-day readmission.

Results: A total of 127 patients (mean age 54.6 ± 13.0 years, 44% female) underwent open liver resection (69 [54%] after ERAS implementation). ERAS protocols were associated with significantly lower rates of ICU admission (47 vs. 13%, p < 0.001), shorter LOS (median 5.3 vs. 4.3 days, p = 0.007), and lower median costs ($3566 less, p = 0.03). Readmission remained low throughout the study period (5% pre-ERAS, 4% during ERAS, p = 0.83). Rates of uncontrolled pain were either the same or better after ERAS implementation through post-operative day #3 (41% pre-ERAS, 23% during ERAS, p = 0.03).

Discussion: The use of TAP block for hepatectomy as part of an ERAS protocol is associated with improved quality and cost of care. Surgeons performing liver resections should consider standardization of evidence-based best practices in all patients.
