Postoperative nutrition in the setting of enhanced recovery programmes

Patients undergoing major surgery for gastrointestinal cancer are at high risk of developing or worsening malnutrition and sarcopenia. In malnourished patients, preoperative nutritional support may not be sufficient and so postoperative support is advised. This narrative review addresses several aspects of postoperative nutritional care in the setting of enhanced recovery programmes. Early oral feeding, therapeutic diet, oral nutritional supplements, immunonutrition, and probiotics are discussed. When postoperative intake is insufficient, nutritional support favouring the enteral route is recommended. Whether this approach should use a nasojejunal tube or jejunostomy is still a matter of debate. In the setting of enhanced recovery programmes with early discharge, nutritional follow-up and care should be continued beyond the short time in hospital. In enhanced recovery programmes, the main specific aspects of nutrition are patient education, early oral intake, and post-discharge care. The other aspects do not differ from conventional care.
