Is ERAS effective and safe in laparoscopic gastrectomy for gastric carcinoma? A meta-analysis.

Background: It is still unclear whether enhanced recovery after surgery is effective and safe in laparoscopic gastrectomy for gastric carcinoma.

Methods: Cochrane library databases, Medline, Embase, and Pubmed were searched from January 1, 1986, to December 31, 2016. Randomized controlled trials (RCTs) comparing fast-track recovery with conventional recovery strategies in laparoscopic radical gastrectomy for gastric carcinoma were included. The main outcomes measured were postoperative hospital stay, time to first flatus, hospital charge, and overall complication rate.

Results: Six RCTs with 400 patients were included in this study. Fast-track surgery has shorter postoperative hospital stays (weighted mean difference (WMD) - 2.65; 95% CI, - 4.01 to - 1.29, z = 3.82, P < 0.01) and less hospitalization expenditure (WMD - 523.43; 95% CI, - 799.79 to - 247.06, z = 3.71, P < 0.01) than conventional recovery strategies. There was no significant difference with respect to duration to first flatus (WMD - 17.72; 95% CI, - 39.46-4.02, z = 1.60, P = 0.11) and complication rate (OR 1.57; 95% CI, 0.82-2.98, z = 1.37, P = 0.17).

Conclusions: Enhanced recovery after surgery is effective and safe and is thus recommended in laparoscopic radical gastrectomy for gastric carcinoma.
