Clinical and imageological features of different pancreatic intraductal papillary Mucinous tumors / 医学研究生学报

ABSTRACT

Objective: To analyze the experience in the treatment of intraductal papillary Mucinous tumors(IPMT) of the pancreas.Methods: We retrospectively analyzed the clinical and imageological features of 30 IPMT patients,17 males and 13 females,who underwent operations in our department from May 2003 to December 2005.The patients with intraductal papillary mucinous adenoma(IPMA) were included in the benign group,and those with intraductal papillary mucinous borderline tumor(IPMB) and intraductal papillary mucinous carcinoma(IPMC) in the malignant group.Results: There were more males than females in the malignant group(76.5% vs 30.8%,P40 mm,which were considered to be the predictors of malignancy.Conclusion: Clinical and imageological features differ signifcantly between different pathological types of IPMT.The presence or absence of mural nodules,the diameter of the main pancreatic duct and the size of the tumor may help differentiate the malignancy from benignancy of IPMT.
