Clinical Efficacy Analysis on Early Oral Feeding Versus Nasojejunal Early Enteral Nutrition for Patients After Pancreaticoduodenectomy

Pancreaticoduodenectomy is the standard treatment for periampullary and pancreatic head carcinomas, with the high incidence of perioperative complications ranging from 40% to 60%. Malnutrition is a relevant predictor of post-operative morbidity and mortality after pancreatic surgery. Adequate nutrition is the key to reduce perioperative complications, including abdominal infection, poor healing of wounds, and even gastrointestinal anastomotic leak. The optimal nutritional support method after Pancreaticoduodenectomy is still uncertain, and the current nutritional support methods are diverse. The results of an international survey showed that there was very poor or no agreement on postoperative strategies for the management of nutrition after Pancreaticoduodenectomy. Therefore, the investigators designed this retrospective study to evaluate which was safer and more feasible between early oral feeding and nasojejunal early enteral nutrition after Pancreaticoduodenectomy, using the method of propensity score weighting.
