The Effect of PERT on Patients Undergoing Pancreaticoduodenectomy

A comprehensive perioperative nutrition management plan for pancreaticoduodenectomy, primarily based on pancreatic enzyme replacement therapy (PERT). A prospective randomized controlled study was conducted to comprehensively analyze the perioperative nutritional status of patients undergoing pancreaticoduodenectomy, with the aim of exploring: 1. The effect of PERT on postoperative complications and physiological status after pancreaticoduodenectomy; 2. The efficacy of PERT treatment on clinical symptoms, nutritional indicators, and quality of life (QOL) related to pancreatic exocrine dysfunction (PEI) after pancreaticoduodenectomy; 3. The personalized full process nutrition management strategies based on risk factor stratification.
