Protein intakes are associated with reduced length of stay: a comparison between Enhanced Recovery After Surgery (ERAS) and conventional care after elective colorectal surgery.

Protein can modulate the surgical stress response and postoperative catabolism. Enhanced Recovery After Surgery (ERAS) protocols are evidence-based care bundles that reduce morbidity. In this study, we compared protein adequacy as well as energy intakes, gut function, clinical outcomes, and how well nutritional variables predict length of hospital stay (LOS) in patients receiving ERAS protocols and conventional care.
