Efficacy and safety of enhanced recovery after surgery protocol on minimally invasive bariatric surgery: a meta-analysis.

BACKGROUND

Enhanced recovery after surgery (ERAS), a multidisciplinary and multimodal perioperative care protocol, has been widely used in several surgical fields. However, the effect of this care protocol on patients receiving minimally invasive bariatric surgery remains unclear. This meta-analysis compared the clinical outcomes of the ERAS protocol and standard care (SC) in patients who underwent minimally invasive bariatric surgery.

MATERIAL AND

METHODS

PubMed, Web of Science, Cochrane Library, and Embase databases were systematically searched to identify literature reporting the effects of the ERAS protocol on clinical outcomes in patients undergoing minimally invasive bariatric surgery. All the articles published until 01 October 2022, were searched, followed by data extraction of the included literature and independent quality assessment. Then, pooled mean difference (MD) and odds ratio with a 95% CI were calculated by either a random-effects or fixed-effects model.

RESULTS

Overall, 21 studies involving 10 764 patients were included in the final analysis. With the ERAS protocol, the length of hospitalization (MD: -1.02, 95% CI: -1.41 to -0.64, P <0.00001), hospitalization costs (MD: -678.50, 95% CI: -1196.39 to -160.60, P =0.01), and the incidence of 30-day readmission (odds ratio =0.78, 95% CI: 0.63-0.97, P =0.02) were significantly reduced. The incidences of overall complications, major complications (Clavien-Dindo grade ≥3), postoperative nausea and vomiting, intra-abdominal bleeding, anastomotic leak, incisional infection, reoperation, and mortality did not differ significantly between the ERAS and SC groups.

CONCLUSIONS

The current meta-analysis indicated that the ERAS protocol could be safely and feasibly implemented in the perioperative management of patients receiving minimally invasive bariatric surgery. Compared with SC, this protocol leads to significantly shorter hospitalization lengths, lower 30-day readmission rate, and hospitalization costs. However, no differences were observed in postoperative complications and mortality.
