Abstract

BACKGRONDS/AIMS: Patients with a branch duct type intraductal papillary mucinous tumor (IPMT) of the pancreas with hyperplasia are suggested to be followed up without resection. The aims of this study were to compare the clinical, radiologic, and pathologic findings among the subtypes of IPMT and to find the factors that could predict a hyperplastic lesion preoperatively. METHODS: Twenty two patients with IPMT of the pancreas who underwent surgical resection were investigated. The subtypes of IPMT were classified into the main duct type (7 patients), branch duct type (6 patients), and combined type (9 patients) based on the pathologic findings of the surgical specimens. The clinical, radirologic, and pathoiogic findings of each subtype were analyzed. RESULTS: Asymptomatic patients were more common in the branch duct type of IPMT (p=0.01). The diameter of the main pancreatic duct was <7 mm in most of the branch duet types of IPMT (5/6). Hyperplastic lesions were more likely to be the branch ciuct type (5/6, p=0.01). CONCLUSIONS: A hyperplastic lesion can be predicted if a lesion is the branch duct type of IPMT with the diameter of the main pancreatic duct < 7 mm and without symptoms. Therefore, IPMT of the pancreas with these findings can be followed up without an operation.
