本文报道97例胰头及壶腹癌(胰头、壶腹、胰内胆总管癌各43、48、6例)的临床病理分析。三者虽临床表现相似,但于肉眼形态、镜下所见及侵犯、转移方式上仍各有其不同特征。以整体切除标本对上述3种癌肿与胰内胆总管的关系研究发现,癌肿侵犯胆总管发病率较高。胰头癌不论大小、早晚,均以环状肌内浸润方式侵入胆总管,伴有不同程度促结缔织 This article reported 97 cases of pancreatic head and ampullary carcinoma (pancreatic head, ampulla, pancreatic ductal carcinoma, 43 cases, 48 ​​cases, 6 cases) clinical pathological analysis. Although the clinical manifestations of the three are similar, they still have different features in terms of the naked eye morphology, microscopic findings, invasion, and metastasis. The relationship between the above three types of cancers and the common pancreatic ducts was found in the whole resection specimens. The incidence of cancer invasion of common bile ducts was high. Pancreatic cancer regardless of size, sooner or later, are infiltrated into the common bile duct with a circular intramuscular infiltration, with varying degrees of promoting connective tissue.
