[Pharmacological test with cerulein during manometric cholangiography via external biliary drainage].
The manometric post-operative cholangiography through external drainage is now a method of everyday use. However in some cases the substenotic appearance of the terminal bile tract and of the Oddi's sphincter gives rise to doubts as to the real cause of this alteration. Caerulein solves the functional hypertone. It also starts a good peristalsis of the terminal bile tract, reducing the intrabiliary pressure and causing an evident transpapillary passage. Thus, the use of this substance allows a differential diagnosis between organic or functional stenosis.
