Pancreatoduodenectomy removes the gallbladder, most of the distal stomach, duodenum, pancreas and other organs and tissues, and the reconstructed channels of stomach, biliary tract and intestine are not in line with physiology. Diet should follow the requirements of combined resection of stomach, gallbladder, pancreas and intestine step by step. In the early stage, the diet was mainly liquid-low slag, low fat and semi-liquid-soft and excessive, and the diet was gradually released after 1-3 months. If the patient recovers smoothly, you can try eating a little pigeon meat and drinking clear soup. If possible, he can put pigeons on the nutrition menu during the recovery period.
