数字减影技术经内镜逆行胰腺实质造影（附47例报告）

本研究在国内首次将经内镜逆行胰管造影（ＥＲＰ）与数字减影技术结合，以获取胰腺实质造影像。对４７例同时行ＥＲＰ及实质造影相比较。造影使用非离子型造影剂。结果胰腺正常３５例，慢性胰腺炎７例，胰腺癌５例。胰实质显示率６５．９％，２例并发轻度急性胰腺炎。分析了正常及异常胰实质像的造影表现，认为在ＥＲＰ时获取胰实质的数字减影像是安全可行的。减影图像能清晰显示胰实质病变，对慢性胰腺炎及早期胰腺癌的诊断优于常规ＥＲＰ。此法可选择性用于临床疑有胰腺病变者

Endoscopic Retrograte Pancreatic Parenchymography by Digital Subtraction Techniques: Report of 47 Cases

Digital subtraction techniques were used during endosoopic retrograte Pancreatography in the study toobtain the Pancreatic parenchymograph. 47 cases were expeured to Pancreatic Parenchymography and routine Pancreatography simutaneousiy. Both results were comparisoned. of the 47 cases, 35 showed a normal gland. Chronic Pancreatitiswere found in 7 cases and carcinoma of the Pancrea in 5 patients. The contrast material used was non - ionic contrast media.The Pancreatic parenchyma was well demonstated in 31 out of 47 cases (65. 9 % ). 2 cases developed clinical evidence of mildacute Pancreatitis. Both normal and abnormal abnormal parenchymograph were analysised. It is concluded that digital imagingof the Pancreas during ERP is feasible and safety. It may outline the changes in the parenchyma of the mpncreas and is betterthan routine ERP for the early diagnosis of Pancreatic carcinoma as well as chronic pancreatitis. The method may be used inpatients suspected of Pancreatic diseases.
