Background: The enhanced recovery after surgery (ERAS) protocol integrates a number of perioperative interventions and techniques, aiming at decreasing the morbidity rate and the length of postoperative hospital stay after surgery. Although it has become a standard perioperative management for colorectal surgery, the feasibility of the ERAS protocol for gastric surgery remains unclear.
Methods: This single-center, prospective phase II study included patients with gastric cancer undergoing curative gastrectomy. The primary end point was the incidence of Clavien-Dindo grade II or higher postoperative complications. The secondary end points were the incidence of anastomotic leakage, the incidence of pneumonia, the proportion of patients starting oral feeding at postoperative day 2, the completion rate of the ERAS protocol, the length of postoperative hospital stay, the readmission rate within 30 days after discharge, and the mortality rate.
Results: From September 2013 to September 2014, 121 eligible patients were enrolled in this study. The incidence of postoperative complications was 10.7 % (90 % confidence interval, 6.47-16.54 %). Anastomotic leakage and pneumonia was observed in one and zero patients, respectively. The median length of postoperative hospital stay was 8 days, and the completion rate of the ERAS protocol was 85.1 %. The readmission rate and the mortality rate were 0 %.
Conclusions: The ERAS protocol can be safely used in patients undergoing gastric cancer surgery. The superiority of the ERAS protocol over non-ERAS perioperative management should be clarified.
