Pancreatic ipmn i.e. pancreatic intraductal papillary mucinous adenoma, pancreatic intraductal papillary mucinous adenoma 2cm requires surgery. Early surgical resection of pancreatic intraductal papillary mucinous adenoma is the only curable means therefore, otherwise there is a risk of cancer. Therefore, pancreatic intraductal papillary mucinous adenoma 2cm requires surgery. Intraductal papillary mucinous adenomas of the pancreas can be divided into main pancreatic duct type, branch pancreatic duct type, and mixed type. The main pancreatic duct type has a higher malignant proportion and should be treated aggressively with surgery; the branch pancreatic duct type needs to be considered for surgery if the diameter of the tumor is greater than 2.5 cm, the diameter of the cystic wall nodule is greater than 0.6 cm, and the dilatation of the main pancreatic duct is greater than 0.7 cm; and the mixed type of tumors exists in both the main pancreatic duct and the branch pancreatic ducts, and therefore, also needs to be treated with surgery. Common surgical treatments for intraductal papillary mucinous adenomas of the pancreas include pancreatic body-tail resection, pancreaticoduodenectomy, and local excision. Intraductal papillary mucinous adenoma of the pancreas 2cm should be selected under the guidance of a doctor to avoid adverse effects.
