胰腺导管粘液性增生(mucinous hyperplasia)是指导管上皮的粘液性增生,可有两种,即胰腺大导管粘膜上皮乳头状增生和小导管腺瘸样增生(以下称为小导管化生).有实验提示导管粘液性增生,特别是乳头状改变的发生多与胰腺癌有关.有人认为导管粘液性增生可能为胰腺癌的癌前期病变.但是,如果在非癌胰腺中也有导管粘液性增生,那么这种推测就不能成立.另一种观点认为导管粘液性增生为一种对某些增生性刺激的化生反应.本文的目的为:1.用组织学方法观察非癌性胰脏中从预定部位取样的组织,搞清非癌性胰腺导
Mucinous hyperplasia of the pancreas guides mucinous hyperplasia of the duct epithelium. There are two types of pancreatic ductal papillary hyperplasia and small ductal glandular hyperplasia (hereinafter referred to as small duct metaplasia). Experiments suggest that mucinous hyperplasia of the catheter, especially papillary changes, is associated with pancreatic cancer. Some people think that mucinous hyperplasia of the catheter may be a precancerous lesion of pancreatic cancer. However, if there is mucinous hyperplasia of the catheter in non-cancerous pancreas, then This hypothesis cannot be established. Another view is that catheter mucinous hyperplasia is a metaplastic response to certain proliferative stimuli. The purpose of this article is: 1. To observe histologically from non-cancerous pancreas Sampling tissue at site to identify non-cancerous pancreatic cancer
