Dose–response relationships between early postoperative nutrition and subsequent complications in gastrointestinal cancer: optimal intake ranges for energy and protein (opens in new tab)

Background and aimPostoperative complications remain common after major gastrointestinal (GI) cancer surgery. Although early nutritional support is a core component of enhanced recovery protocols, optimal postoperative targets for energy and protein intake remain uncertain. This study aimed to characterize dose–response relationships between early postoperative nutritional intake and postoperative complications.MethodsThis prospective observational cohort included adults undergoing elective g...
