Management strategy for multifocal branch duct intraductal papillary mucinous neoplasms of the pancreas.

摘要: OBJECTIVES: Branch duct intraductal papillary mucinous neoplasms of the pancreas (BD-IPMNs) often are composed multifocal lesions. We aimed to clarify clinicopathologic features BD-IPMNs. METHODS: Medical records 211 patients with BD-IPMNs (169 solitary and 42 multifocal) were retrospectively analyzed. compared pathological grade resected IPMNs resulting clinical course between RESULTS: Sixty-nine (54 15 BD-IPMNs) underwent pancreatectomy, these patients, 62 exhibited at least 1 malignant predictor. There was no significant difference in prevalence malignancy 2 groups. In remaining 142 who predictors, both groups demonstrated differences morphologic changes Seventeen distinct ductal carcinomas identified groups, there carcinoma Moreover, disease-specific survival rate CONCLUSIONS: BD-IPMNs, resection is only warranted for lesions that exhibit predictors; moreover, closer attention potential presence or development warranted.
