Pancreatography with contrast medium containing polyethylene hydrogenated castor oil

A new contrast medium has been used for endoscopic pancreatography. Good visualization of the pancreas was obtained by this method. No side-effects of this method were observed by clinical and histologic examination, either in clinical or experimental studies. Clinically, the new method provided more detailed information regarding pancreatic changes in chronic pancreatitis. It is suggested that this method may make detection of a small tumor of the pancreas in the parenchyma and permit earlier diagnosis of carcinoma of the pancreas.
