Enhanced recovery after liver surgery in cirrhotic patients: a systematic review and meta-analysis

Abstract

Abstract Background Few studies have assessed enhanced recovery after surgery (ERAS) in liver surgery for cirrhotic patients. The present meta-analysis assessed the impact of ERAS pathways on outcomes after liver surgery in cirrhotic patients compared to standard care. Methods A literature search was performed on PubMed/MEDLINE, Embase, and the Cochrane Library. Studies comparing ERAS protocols versus standard care in cirrhotic patients undergoing liver surgery were included. The primary outcome was post-operative complications, while secondary outcomes were mortality rates, length of stay (LoS), readmissions, reoperations, and liver failure rates. Results After evaluating 41 full-text manuscripts, 5 articles totaling 646 patients were included (327 patients in the ERAS group and 319 in the non-ERAS group). Compared to non-ERAS care, ERAS patients had less risk of developing overall complications (OR 0.43, 95% CI 0.31–0.61, p < 0.001). Hospitalization was on average 2 days shorter for the ERAS group (mean difference − 2.04, 95% CI − 3.19 to − 0.89, p < 0.001). Finally, no difference was found between both groups concerning 90-day post-operative mortality and rates of reoperations, readmissions, and liver failure. Conclusion In cirrhotic patients, ERAS protocol for liver surgery is safe and decreases post-operative complications and LoS. More randomized controlled trials are needed to confirm the results of the present analysis.
