胰腺导管内乳头状黏液性肿瘤(intraductal papillary mucinous neoplasms of the pancreas,IPMN)是一种较少见的有恶变潜能的胰腺囊性肿瘤,好发于老年人,最多见于60～70岁,男女发病比例约2:1。 其起源于胰腺导管上皮,呈乳头状生长,因分泌过多的黏液,会引起主胰管和(或)分支胰管进行性扩张或囊变,扩张可出现在胰管的...
根据肿瘤发生部位不同,IPMN可分为三型:(1)分支胰管型(BD-IPMN):肿瘤主要存在于分支胰管、分支胰管扩张;(2)主胰管型(MD-IPMN):肿瘤主要存在于主胰管、主胰管扩张;(3)混合型(MT-IPMN):BD-IPMN合并MD-IPMN。其中,主胰管型和混合型恶变风险相对较高,分支胰管型风险则较低。 为更好的明确IPMN的部位和性质,医...

The optimal operative strategy for extensive multifocal BD-IPMN and diffuse main-duct IPMN is more controversial, because in these circumstances the entire gland may be at equal risk of high-grade dysplasia or microinvasive disease either concurrently or in the future. Although total pancreatectomy ...
The pancreas after resection of IPMN or concomitant PDAC is still at risk of metachronous development of PDAC. The presence of IPMN in the pancreas seems to pose the entire organ at increased risk for developing carcinoma, and then surveillance of the entire pancreas is needed to detect distinct...
Branch duct intraductal papillary mucinous neoplasms of the pancreas (BD-IPMN) without malignant features rarely developed into invasive cancer. However, invasive cancer is aggressive once an invasive change occurs. We report three cases of invasive cancers which developed i...
With increasing indence and peculiar clinico-pathological features, intraductal papillary mucinous neoplasm (IPMN) of the pancreas has been a major interest in the field of pancreatology. Although pathologic and clinical diversities make difficulty in decision of treatment of IPMN in some circumstances, ...
