Preoperative Nutrition and Postoperative Discomfort in an ERAS Setting: A Randomized Study in Gastric Bypass Surgery.

This study was undertaken to investigate the potential value of different models for preoperative hydration/nutrition, in addition to our ERAS (enhanced recovery after surgery) protocol.
