The effect of the surgery on the TSH and on the extra thyroid T4 metabolism was studied in thirty euthyroid patients. The TSH showed a light increase thirty minutes after the skin cut. There were no remarkable changes of T4 serum levels, while the serum triiodothyronine concentration fell during and after the operation, with a concomitant rise in reverse triiodothyronine.
