The role of caerulein in differentiating functional narrowing of the distal common bile duct from organic stenosis was studied in 146 patients. Caerulein caused a generalized contraction of the extrahepatic biliary tract and a contraction of the sphincter of Oddi. It therefore improved opacification of the tract, particularly of the terminal portion, which is often not demonstrated by traditional techniques. The appearance of the duodenographic effect allowed for the evaluation of functional factors, which often play a role in stenosis of the sphincter of Oddi. Also, the reduction of bile-duct caliber revealed previously undetected filling defects.
在146例患者中研究了蛙皮素在鉴别胆总管远端功能性狭窄与器质性狭窄中的作用。蛙皮素可引起肝外胆道的普遍性收缩及奥迪括约肌的收缩。因此，它改善了胆道的显影，尤其是末端部分，而这部分通常无法通过传统技术显示出来。十二指肠造影效应的出现有助于评估功能性因素，这些因素在奥迪括约肌狭窄中常起作用。此外，胆管管径的缩小还揭示了先前未被发现的充盈缺损。
