Perioperative Immunonutrition for Patients Undergoing CRS and HIPEC

Patients with peritoneal disease commonly present with symptoms of abdominal distension and subacute intestinal obstruction. This results in poor oral intake leading to these patients often presenting in a malnourished state. CRS and HIPEC can potential provide improve survival for these patients, however can be a hazardous procedure, involving multi-organ resections. The risk is especially high in poorly nourished patients. The study investigators hypothesize that perioperative immunonutrition can reduce wound infections and length of hospital stay, and improve perioperative outcomes. To the investigators' knowledge, it has not been evaluated in patients undergoing CRS and HIPEC.
