胰腺肿瘤的早期诊断和鉴别诊断非常困难，术前定性仍缺乏理想的手段，由于胰腺癌９５％以上由胰腺导管上皮而来，故在行诊断性ＥＲＣＰ的同时结合胰管刷检（ｐａｎｃｒｅａ－ｔｉｃ ｄｕｃｔ ｂｒｕｓｈｉｎｇ. ＰＤＢ）细胞学诊断技术有助于提高胰腺癌的诊断正确率，本文探讨?
The early diagnosis and differential diagnosis of pancreatic tumors is very difficult, and the ideal method is still lacking in preoperative characterization. Since more than 95% of pancreatic cancers come from the pancreatic ductal epithelium, diagnostic ERCP is combined with pancrea-tic examination. Duct brushing.
