The application of enhanced recovery after surgery (ERAS)/fast-track surgery in gastrectomy for gastric cancer: a systematic review and meta-analysis.

BACKGROUND

The study aimed to compare the safety and effectiveness of Enhanced recovery after surgery (ERAS) with conventional care in gastrectomy for gastric cancer.

METHODS

Search strategy from Pubmed, Embase, Web of science, Cochrane library and reference lists was performed. The collected studies were randomized controlled trials and published only in English, and undergoing ERAS in gastrectomy for gastric cancer from January 1994 to August 2016.

RESULTS

A total of eight studies including 801 patients were included. There were 399 cases in the ERAS and 402 cases in the conventional care groups. Meta-analysis showed that time to first passage of flatus (weighted mean difference (WMD) -14.57; 95% confidence interval (CI) -20.31 to -8.83, <0.00001), level of C-reaction protein (WMD -19.46; 95 % CI -21.74 to -17.18, <0.00001) and interleukin-6 (WMD-32.16; 95 % CI -33.86 to -30.46,<0.00001) on postoperative days, postoperative hospital stay (WMD -1.85; 95 % CI -2.35 to -1.35, <0.00001), hospital charge (WMD -0.94, 95 % CI, -1.40 to 0.49, <0.0001) were significantly decreased for ERAS, but increased readmission rates (odds ratio (OR), 3.42, 95 % CI, 1.43 to 8.21, P=0.006). There were no statistically significant differences in intraoperative blood loss, operation time, number of retrieved lymph nodes, duration of foley catheter and postoperative complications (>0.05).

CONCLUSIONS

ERAS is considered to be safe and effective in gastrectomy for gastric cancer. Further larger, multicenter and randomized trials were needed to beresearched.
