| [ Summary ] |
We described the current methods and the usefulness of intraductal ultrasonography (IDUS) and peroral pancreatoscopy (POPS) for differentiating between benign intraductal papillary-mucinous tumors (IPMT) and malignant ones.
IDUS images of IPMT revealed cystic lesions with mural nodules, a distinct cystic wall, mucous echoes, and solid tumors with mixed echo patterns. The classification of IDUS images of IPMT was considered to be useful for differential diagnosis of benign and malignant IPMT. Protruding lesions were identified in IPMT with POPS. The type which was fish-egg-like, as seen with vascular images. The villous type, and the vegetatine type were considered to be malignant. |
