There are many types of pancreatic nodules, including solid nodules, cystic nodules, cystic nodules and so on. Therefore, if a nodule is found in the pancreas, you should go to the hospital for further examination in a timely manner. You can have a thin-layer enhancement CT of the pancreas plus 3D reconstruction to further clarify the nature of the nodule; you can also have an MRI of the pancreas to understand the nature of the nodule. If the nodule is pancreatic cancer, it is usually a solid nodule, which is not enhanced under enhanced CT. If the nodule is found to be pancreatic cancer, radical pancreatic cancer surgery should be performed. If it is in the tail of the pancreas, combined resection of the body and tail of the pancreas can be performed. If it is in the head of the pancreas, pancreaticoduodenectomy should be performed. In case of insulinoma, the patient’s blood glucose is lowered and there is a typical manifestation of Whipple’s triad, and in case of insulinoma, surgery should be performed to remove the insulinoma.
