The presence of latex allergy is becoming more common and can be
serious.  However more centers are becoming aware of this problem and can
now carry out many mediacl and surgocal roceedures without exposure to
latex.  Endoscopically directe d biopsy can be done latex free so long a
careful exclsion of latex is made.  Most endoscopes dont not have latex
components on the insertion tube.  they can have elsewhere.  medications
need to be specially prepared also.
it can also be reasonable to study the patient in a less precise way by
antibodies and absorbtion tests.
