Cystic adenoma of the pancreas is a relatively common pancreatic neoplastic lesion in clinical practice. The sequelae after surgery are mainly as follows: First, elevated blood sugar. Due to the large size of pancreatic cystic adenoma, more pancreatic parenchymal tissues may be removed during surgery, and the insulin content secreted by the pancreas decreases significantly after surgery, causing patients to have significantly elevated blood sugar levels and even diabetes. Some patients need to take glucose-lowering medication for life to maintain stable blood sugar. Second, pancreatic fistula, if the pancreatic-intestinal anastomosis suture is not secure, extravasation of pancreatic fluid into the abdominal cavity due to abdominal infection can cause pancreatic fistula, which can lead to serious abdominal infection and serious complications. Third, adhesive intestinal obstruction, due to the change of the normal physiological structure of the intestine during surgery, the intestinal canal can be adhered after surgery, making it difficult for the intestinal contents to pass, resulting in abdominal pain, abdominal distension and other manifestations of intestinal obstruction in patients.
