摘　　要：目的探讨胰腺癌ERCP所见与肿瘤大小和分期的关系。方法选择手术和病理证实为胰腺癌、ERCP影像清晰的患者35例,根据ERCP片子测量主胰管和胆总管狭窄长度,并测量胰胆管梗阻远端直径。将胰腺癌肿瘤大小(TS)和JPS T分类与ERCP所见的关系进行相关性分析。结果35例中25例ERCP主胰管狭窄,10例中断(7例导丝通过梗阻部位显示病变长度),31例胆总管狭窄。35例肿瘤大小与胰管和胆总管狭窄长度的相关系数分别为0．709(P=0．0001)和0．540(P= 0．0053),JPS T分类与胰管狭窄长度的相关系数为0．514(P=0．0052)。结论胰腺癌ERCP胰管狭窄长度与肿瘤大小和分期呈正相关,但狭窄段短者与肿瘤大小及分期并非完全一致,胆管狭窄长度对预测胰头肿瘤大小亦有作用。Objective To study on ERCP findings correlating with tumor size and staging of pancreatic cancer（PC）. Methods We selected 35 patients with PC who were identified by surgery and/or pathology and had undergone ERCP with clear imaging findings. The lengths of pancreatic duct and common bile duct stricture as well as the diameter of upstream dilated pancreatic or bile duct were measured on ERCP films. The ralationship among ERCP findings and tumor size and JPS T-stage of PC were analysed by correlation analysis. Results Of the 35 patients with PC, ERCP showed the pancreatic duct stricture in 25 and cutoff of pancreatic duct in 10 （7 of them, the lesion lengths were revealed after a guide wire advanced beyond the obstructive site） and common bile duct stricture in 31. The correlation coefficients between tumor size and lengths of pancreatic duct or common bile duct stricture were 0. 709（P =0. 0001 ） and 0. 540 （P =0. 0053） respectively. The correlation coefficient between JPS T-stage and lengths of pancreatic duct stricture was 0. 514 （ P = 0. 0052）. Conclusion The length of pancreatic duct stricture in ERCP was positively correlated with the tumor size and staging of PC. But it is not consistent when the length of stricture is rather short. The lengths of bile duct stricture also have some effects on predicting the tumor size of pancreatic head cancer.
