Transnasal jejunal tube
A naso-jejunal tube was placed in the operation, which is placed 15 cm below Traitz's ligament. A short-peptide enteral nutrient solution was heated by an enteral nutrient pump and infused into the patients within 24 hours after the operation. Before and at the end of the infusion, physiological saline was given to flush the tube, and at the end of the infusion, the catheter was closed to prevent liquid reflux and blockage of the tube. The catheter should be clamped shut at the end of the infusion. During the infusion period, the patient's gastrointestinal tolerance was dynamically evaluated. According to the results of a regular review of nutritional indicators, including hemoglobin, albumin, electrolytes, liver and kidney function, etc., increase the amount of enteral nutrients; remove the nasojejunal tube when the patient has no abdominal distension after exhaustion and feeding; and change to feeding through the mouth.
Transvenous access
A uniform drip of nutritional solution was started 24 hours postoperatively. Configuration of nutritional solution: glucose and medium/long-chain fat emulsion as the main energy substances to provide calories, calculated at 30 \~ 35 kcal/(kg-d), glucose-fat ratio is 6:4, pancreatic glucose ratio for those without a history of diabetes mellitus is 1:6 \~ 8, and for diabetic patients depending on the level of glucose, pancreatic glucose ratio is 1:3 \~ 4, and then assisted with subcutaneous injections of insulin to control glucose, if necessary. Pay attention to the total amount of rehydration fluid, electrolytes, vitamins, and trace elements supplemented. Mix the nutrient solution evenly in the laminar flow clean table and infuse it through the route at 2500\~3000 ml/d; the infusion time is 8\~12 h/d. After exhaustion, start to eat through the mouth.
