Nutrition practices with a focus on parenteral nutrition in the context of enhanced recovery programs: An exploratory survey of gastrointestinal surgeons.

Background & Aims: Ensuring patients have adequate physiological reserves to meet the demands of major surgery may necessitate nutritional prehabilitation and perioperative medical nutrition therapy (MNT). Parenteral nutrition (PN) via central or peripheral routes is indicated when requirements cannot be met orally or enterally. While patients undergoing major gastrointestinal (GI) surgery are at high nutritional and catabolic risk, guidance on PN is limited in Enhanced Recovery After Surgery (ERAS) protocols.

Perioperative peripheral parenteral nutrition to support major gastrointestinal surgery: Expert opinion on treating the right patients at the right time.

Background & Aims: Patients undergoing major gastrointestinal surgery may be in particular need of nutritional therapy due to potential pre-existing disease-related malnutrition and the impact of surgical procedures. Peripheral parenteral nutrition (PPN), delivered via a peripheral catheter, is aligned with the Enhanced Recovery After Surgery (ERAS) concept of minimally invasive interventions where possible. However, uncertainties regarding perioperative PPN for patients undergoing major gastrointestinal surgery arise, in part, due to lack of clinical guidelines.
