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
This study, for the first time in China, combines endoscopic retrograde pancreatic ductography (ERP) with digital subtraction to obtain images of the parenchyma of the pancreas. 47 cases of simultaneous ERP and the actual comparison of imaging. Contrast using non-ionic contrast agent. Results 35 cases of normal pancreas, chronic pancreatitis in 7 cases, 5 cases of pancreatic cancer. Pancreatic parenchyma showed 65.9%, 2 cases complicated by mild acute pancreatitis. Analysis of normal and abnormal pancreatic parenchyma imaging performance, that the acquisition of pancreatic parenchyma digital subtraction image is safe and feasible. Subtraction images can clearly show the pancreatic parenchymal disease, the diagnosis of chronic pancreatitis and early pancreatic cancer is superior to conventional ERP. This method can be used for clinical suspicion of pancreatic lesions
