Abstract:
Objective To study on ERCP findings correlating with tumor size and staging of pancre- atic cancer(PC).Methods We selected 35 patients with PC who were identified by surgery and/or pathol- ogy 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 correla- tion analysis.Results Of the 35 patients with PC,ERCP showed the pancreatic duct stricture in 25 and cut- off 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.
