Dear Professor Einar Arnbjörnsson,

Thank you for having raised the issue of the appropriateness of the barium enema, what is very important for pediatric surgeons and radiologists. I think there is a mistake to simplify the indications for the use of different contrast agents. The barium enema is not abandoned. It is used not as widespread as before, but it has its testimony: inflammatory diseases of the colon [1]; for cancer diagnosis (rare) [2,3]; for diverticular hemorrhage treatment [4]; polyposis  and fistulos diagnosis [5];and diagnosis of the megacolon, including Hirschsprung disease, Chagos diseases,  and functional constipation. This is due to the fact that the barium is deposited on the mucosa and makes clearer the transition zone in Hirschsprung disease and improves the visualization of the mucosa in any forms of colon inflammation (colitis).

Water-soluble contrast enema is used: after surgery, where possible leakage of the contrast medium into the abdominal cavity; in colostography for  visualization of the urethral fistula;  in the treatment  of the sigmoid colon volvulus.

You are right, there are some differences between these contrast media. The solution used at my department are indeed isotonic, but no doubt different from the abandoned Barium enema. I intend to ask my radiologists on his point of view.

Sincerely yours

Professor Einar Arnbjörnsson

Professor Einar Arnbjörnsson, thanks for your letter!

   A barium suspension is chemically inert and completely safe in any amount. Water-soluble contrast media are hypertonic solutions. They cause an increase of the bowel tone and so frequently used for the colon cleansing.  The increasing tone leads to narrowing of the colon lumen and decrease of its volume. Thus, the principle of standardization of the method is violated and the results of such study are not reliable. Furthermore, the use of large volumes of hypertonic saline is not safe for the patient.  It seems to me that this is an example of that medicine walks on the trail of that imposed on us by the manufacturers of drugs and devices.

  

Your faithful

Levin M.

Dear colleague!

I do enjoy your writing.

My radiologist do not use barium contrast any more. Instead they favor water soluble contrast media, Omnipack or Visipack.

We usually do not ask for the size of the colon but are interested in the recto-anal inhibitory reflex and variations in lumen size only.

But your opinion is of value and should be published,

Your faithful

Professor Einar Arnbjörnsson
