BackgroundEnhanced recovery after surgery (ERAS) programmes aim to improve postoperative outcomes. They are being utilized increasingly in hepatic surgery. This review aims to evaluate the impact of ERAS programmes on outcomes following liver surgery.MethodsEMBASE, MEDLINE, PubMed and the Cochrane Database were searched for trials comparing outcomes in patients undergoing liver surgery utilizing ERAS principles with those in patients receiving conventional care. The primary outcome was occurrence of postoperative complications within 30 days. Secondary outcomes included length of stay (LoS), functional recovery and adherence to ERAS protocols.ResultsNine articles were included in the review, of which two were randomized controlled trials (RCTs). Overall complication rates were 25.0% (range: 11.5-46.4%) in ERAS patients, and 31.0% (range: 11.8-46.2%) in conventional care patients. Significantly reduced overall complication rates following ERAS care were demonstrated by a meta-analysis of the data reported in the two RCTs (odds ratio: 0.49, 95% confidence interval 0.28-0.84; P = 0.01) The median LoS reported by the studies was 5.0 days (range: 2.5-7.0 days) in ERAS patients, and 7.5 days (range: 3.0-11.0 days) in non-ERAS patients. Recovery milestones, when reported, were improved following ERAS care.ConclusionsThe adoption of ERAS protocols improves morbidity and LoS following liver surgery. Future ERAS programmes should accommodate the unique requirements of liver surgery in order to optimize postoperative outcomes.© 2014 International Hepato-Pancreato-Biliary Association.
