Core Tip

Core tip: To the best of our knowledge, this is the first meta-analysis of randomized controlled trails that have investigated the impact of enhanced recovery after surgery (ERAS) programs on surgical outcomes in liver surgery patients. The implementation of ERAS programs is safe and effective for liver surgery. However, we found some problems, which involved inconsistent outcome measures and ERAS criteria that were not specific to liver surgery. Future research in this field should develop liver surgery-specific ERAS programs.
