在解剖上,胰腺位于门静脉系统的前方,仅其钩突处于肠系膜上动、静脉的后方,且与胆总符和主胰管的行程之间有一定的距离,故发生于钩突的恶性肿瘤有如下特点:缺乏黄疸和严重的疼痛等明显的症象;实验室检查正常;早期胰胆功能无损害;手术切除率低;术后生存期短。因此,早期发现和处理钩突癌是相当困难的。 In the anatomy, the pancreas is located in front of the portal venous system. Its uncinate process is only behind the mesenteric artery and vein, and there is a certain distance between the gallbladder and the main pancreatic duct, so it occurs in the uncinate malignancy. The following features: lack of obvious symptoms such as jaundice and severe pain; normal laboratory tests; early pancreatic and gallbladder function without damage; low surgical resection rate; Therefore, early detection and treatment of uncinched cancer is quite difficult.
