[Scintigraphy using indium-111-oxine as an aid to transrectal echography in the diagnosis of perianal abscess]

The paper describes the authors experience relating to the use of indium-111-oxine scintigraphy as an aid to transrectal echography in the diagnosis of difficult anal fistulas. This method has proved useful in locating otherwise undetected accumulations and in controlling the outcome of operations with a "slow resolution" of the surgical wound. The marker showed a good level of resolution in that, as already shown in the case of chronic inflammatory diseases, marked leukocytes are prevalently located on the site of infection.
