[Drug follow-up therapy after resection of hyperthyroid struma].

By means of a hormone prophylaxis the number of recidivations after the operation of a hyperthyreotic struma could be decreased from 40% to 11%. Recidivations appeared exclusively in doses of equivalency below 50 microgram triiodine thyronine/die. Their number was four times larger, when the hormone prophylaxis was begun only weeks to months after operation. The tendency to neglect the prophylaxis which becomes clearer with the time renders a strong leading by the physician necessary.
