Dietary precautions after pancreaticoduodenectomy include: 1. During the recovery period: eat a liquid diet and a light diet, usually gradually under the guidance of a physician in the hospital; 2. After the recovery period: eat mainly easy-to-digest soft foods, and eat less larger vegetables, vegetable stems, and foods with stems. The removal of part of the pancreas may affect the digestive function to a certain extent due to impaired exocrine function, so it is necessary to supplement digestive drugs, such as pancreatic enzyme preparations, while eating. In addition, after laparotomy, intestinal adhesions lead to intestinal motility disorders, so additional drugs to promote intestinal motility, such as laxative or laxative drugs, should be given.
