[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.
