Observing Energy Needs and Nutritional Support After Pancreatic Surgery for Tumor Recovery in Adults

What this Trial Is About

This observational study focuses on adults undergoing total or partial pancreatectomy for pancreatic tumors. It aims to measure and compare the resting energy expenditure REE using indirect calorimetry with standard predictive equations and weight-based targets. The study seeks to clarify how well clinicians can estimate energy needs without calorimetry and how nutrition delivery routes and adequacy affect postoperative recovery in this high-risk surgical population. Participants receive pancreatic surgery and their energy expenditure is measured with a Cosmed Q-NRG indirect calorimeter during the early postoperative period under controlled conditions. Their postoperative nutrition routeenteral, parenteral, or combinedis recorded without study assignment, reflecting clinical decisions. Nutritional intake, diet-related symptoms, and feeding details are documented alongside clinical outcomes such as complications and mortality. Participants are assessed preoperatively, during hospitalization, at discharge, and at 3 to 6 months post-surgery. Measurements include body weight, BMI, nutritional risk screening, laboratory markers, and clinical variables. Researchers evaluate the accuracy of energy need estimations, nutritional delivery, and clinical outcomes like length of hospital stay, complications, and mortality up to 180 days after surgery.
