Nutritional support in patients undergoing hepatobiliary surgery: trends, recent advances and controversies / 中华肝胆外科杂志

ABSTRACT

Patients undergoing hepatobiliary surgery are very vulnerable to malnutrition while surgeons' knowledge on evidence-based guidelines in surgical nutrition remains poor. Efforts are therefore necessary to implement routine nutritional screening and nutritional support. Rea sonable measures in perioperative nutritional intervention ameliorate pre- and postoperative status of the patient and reduce surgical complications through regulation of immunity,adjustment of glucose concentration and maintenance of tissue and organ functions. Modern surgical achievements using fast- track surgery and minimally invasive surgery provide the opportunity to focus on early intestinal feeding to hepatobiliary surgery patients in the postoperative period.Perioperative nutrition support not only provides nutritional substrates but also modifies the composition of nutritional regimen by adding supernormal doses of specific substrates to improve surgical outcomes. As a consequence,the term “nutrition therapy” instead of “nutrition support” is more acceptable in this era of immunonutrition.
