Preoperative carbohydrate volume optimization in ERAS-guided minimally invasive gastrectomy: a single-blinded RCT assessing gastric residuals and metabolic safety profiles

In gastric cancer patients undergoing elective laparoscopic radical gastric cancer surgery, consumption of 200 ml and 400 ml of carbohydrate beverages 2 h before surgery did not significantly increase gastric residual volume, acidity, or perioperative complications, and no significant differences in intraoperative hemodynamics were observed. Increasing preoperative oral intake within safe limits may further reduce thirst and hunger scores. Individualized adjustment of rehydration volume is recommended for elderly or obese patients.
