Intraductal Papillary Mucinous Neoplasms of the Pancreas: Clinicopathologic Characteristics and Long‐Term Follow‐Up After Resection

Abstract

Resection of all main duct IPMNs seems to be reasonable. Invasive IPMNs were associated with significantly worse survival than noninvasive IPMNs. Although the diameter of cystic lesions was a predictor of malignancy for branch duct and mixed-type IPMNs, precise preoperative identification of malignancy was difficult. Therefore, these lesions should be managed by aggressive resection before invasion occurs to improve survival.
