Abstract
Abstract Background Defined criteria for the resectability of liver disease continue to be refined. In the era of enhanced recovery after surgery (ERAS), data regarding its safety and efficacy in specific patient populations is required. Patients with liver cirrhosis are particularly vulnerable, owing to both operative and peri-operative risk. However, the application of ERAS in cirrhotic patients undergoing hepatectomy is absent from the most recent ERAS Society Group recommendations from 2022. We present a meta-analysis assessing outcomes after liver resection in patients with cirrhosis following an ERAS protocol compared to standard post-operative care. Method A systematic literature search was performed using PubMed, Embase and Web of Science. Studies were included if comparing ERAS protocols versus standard post-operative care in patients undergoing liver resection in which more than 50% of the patient population had cirrhosis at time of surgery. The primary outcome analysed was overall complication rates with secondary outcomes of post-operative mortality, estimated blood loss, operation time, post-operative incidence of liver failure, readmission and reoperation rates. Statistical analysis was performed using Review Manager by the Cochrane Collaboration. Results 930 records were screened for eligibility. Five articles were eligible for inclusion(ERAS n = 425 vs control group n = 423 patients). Cirrhotic patients enrolled in an ERAS program post-hepatectomy had a significantly reduced risk of overall complications (OR 0.45, 95% CI 0.33, 0.61, p<0.00001) and a shorter hospital stay when compared to standard post-operative care by 1.8 days (mean difference -1.83, 95% CI -2.22, -1.45, p<0.00001). No significant differences were noted in post-operative mortality, estimated blood loss, operation time, post-operative incidence of liver failure, readmission or reoperation rates between the ERAS group and control. Conclusion Application of an ERAS protocol for patients undergoing liver resection is safe and feasible in cirrhotic patients. ERAS protocols were successful in significantly reducing overall complication rates and length of inpatient hospital stay, and did not negatively impact secondary post-operative outcomes or mortality. ERAS protocols should be reflected in future guidelines, specifically for cirrhotic patients undergoing hepatectomy, and additional research on the utility of ERAS in higher risk patients is encouraged.
