[Pancreatic injection of a tri-iodinated contrast medium. Optic and electron microscopic analysis. Experimental study in the rat].
Using the optical and electron microscope, the authors studied the effects in the rate of cathetersiation of the pancreatic ducts after laparotomy. 62 rats underwent operation, 42 of which received an injection of 30 p.cent urinary radioselectan, 10 an injection of simple isotonic saline and in 10 of which simple catheterisation without injection was carried out. With injection under high pressure, regardless of the substance used, lesions of acute pancreatitis occurred in almost all cases in the short term and in the long term lesions of localised chronic pancreatitis were fairly common. For these reasons, the authors feel that routine parenchymography is contraindicated and that only opacification of the main pancreatic ducts is permissible.
