ARTICLE HIGHLIGHTS
Research background

This study aimed to evaluate the safety of enhanced recovery after surgery (ERAS) in elderly patients with gastric cancer (GC).

Research motivation

Elderly patients usually have a poor physiological function, more comorbidities, and slow recovery after surgery. Although the application of ERAS protocol in elderly patients with GC has been reported. For elderly patients with GC, there is no convincing evidence that the ERAS protocol is a safe and effective measure.

Research objectives

It was necessary for us to find out whether ERAS could be safely implemented in elderly patients.

Research methods

The PubMed, EMBASE, and Cochrane Library databases were used to search for eligible studies from inception to April 1, 2023. The mean difference (MD), odds ratio (OR) and 95% confidence interval (95%CI) were pooled for analysis. The quality of the included studies was evaluated using the Newcastle-Ottawa Scale scores. We used Stata (V.16.0) software for data analysis.

Research results

This study consists of six studies involving 878 elderly patients. By analyzing the clinical outcomes, we found that the ERAS group had shorter postoperative hospital stays (MD = -0.51, I2 = 0.00%, 95%CI = -0.72 to -0.30, P = 0.00); earlier times to first flatus(defecation; MD = -0.30, I2 = 0.00%, 95%CI = -0.55 to -0.06, P = 0.02); less intestinal obstruction (OR = 3.24, I2 = 0.00%, 95%CI = 1.07 to 9.78, P = 0.04); less nausea and vomiting (OR = 4.07, I2 = 0.00%, 95%CI = 1.29 to 12.84, P = 0.02); and less gastric retention (OR = 5.69, I2 = 2.46%, 95%CI = 2.00 to 16.20, P = 0.00). Our results showed the conventional group had a greater mortality rate than the ERAS group. (OR = 0.24, I2 = 0.00%, 95%CI = 0.07 to 0.84, P = 0.03). However, there was no statistically significant difference in the major complications between the ERAS group and the conventional group (OR = 0.67, I2 = 0.00%, 95%CI = 0.38 to 1.18, P = 0.16).

Research conclusions

Compared to those with conventional recovery, elderly GC patients who received the ERAS protocol after surgery had a lower risk of mortality.

Research perspectives

Compared to those with conventional recovery, elderly GC patients who received the ERAS protocol after surgery was associated with a lower risk of mortality. ERAS protocol was safe in elderly patients with GC.
