Evaluation of enhanced recovery after surgery for gastric cancer patients undergoing gastrectomy: a systematic review and meta-analysis

Introduction
For complicated surgical patients, enhanced recovery after surgery (ERAS) decreases stress and hospital stays. It accelerates recovery and lowers readmissions, morbidity, and death. ERAS’s effectiveness in stomach cancer laparoscopic-assisted gastrectomy (LAG) or robotic gastrectomy is still debated.

Aim
This study assesses the efficacy and safety of the ERAS program for patients undergoing gastrectomy for gastric cancer.

Material and methods
PRISMA-compliant searches were performed in Medline, Embase, PubMed, the Web of Sciences, and the Cochrane Library databases until March 2023. The search included articles that compared ERAS protocol results for gastric cancer surgery patients to conventional care. RevMan performed meta-analysis, and the Cochrane Risk of Bias Assessment Tool assessed study quality.

Results
This meta-analysis contained 11 carefully chosen randomized controlled trials (RCTs) involving 1790 people. The ERAS group had 902 participants, while the traditional care group had 888. The ERAS group had a shorter post-operative hospital stay, with a weighted mean difference (WMD) of –1.12 days (95% CI: –1.89 to –0.35, p = 0.00001), I² = 89%, and a lower number of patients with post-operative problems, with an odds ratio (OR) of 0.73 (95% CI: 0.55 to 0.97; p = 0.03), I² = 60%.

Conclusions
The ERAS procedure has been shown to be effective as well as beneficial for patients undergoing either laparoscopic-assisted or robotic gastrectomy for gastric cancer, since it lowers post-operative complications and accelerates recovery with improved results.
