Application of enhanced recovery after surgery (ERAS) protocol in radical gastrectomy: a systemic review and meta-analysis

PurposeThis study aimed to assess the safety and efficiency of the enhanced recovery after surgery (ERAS) protocol in radical gastrectomy.MethodsStudies published before February 2019 were searched from EMBASE, PubMed, Cochrane Library and Quanfang databases without language and region restrictions. A total of 15 randomised controlled trials (RCTs) with 1216 participants were included in the analysis, of whom 605 underwent ERAS protocol and 611 received traditional perioperative treatment for radical gastrectomy.ResultsThere was a significant reduction in pulmonary infection (p=0.02) after radical gastrectomy. Further, there was a significant decrease in the length of postoperative hospital days (p<0.00001), first passage time of defection and flatus (p<0.00001), and medical cost (p<0.0001) in the group that received the ERAS protocol. However, the ERAS protocol group had a higher risk for readmission (p=0.007), vomiting (p=0.002) and gastric retention (p=0.0003) compared with the traditional treatment group.ConclusionsERAS protocol application for radical gastrectomy accelerated postoperative recovery, shortened postoperative hospital days and first passage time of defection and flatus, and saved on medical costs, and did not increase the occurrence rate of severe complications.
