Endocrine surgery differs from other procedures by influencing hormonal balances in the body, in particular thyroid, parathyroid and adrenal surgeries as these glands secrete hormones into the blood stream. Such surgeries therefore require special focus on hormones, both before and after surgery, as both too little and too much hormone is undesirable and bad for the patients. The indication for surgery is often overproduction of a hormone, while an undesirable result is hormone deficiency of the gland.

The overall project objective is to improve patients' long-term results after endocrine surgery, including in particular preservation of parathyroid gland function after neck surgery and adrenal gland function after removal of adrenal nodules.
