This study tried to highlight the predictive value of the morning postoperative cortisol levels, which can act as the prognosis value of the postoperative pituitary function, providing future medication advices for improving patients' safety of drugs.

Transsphenoidal adenomectomy usually accompanied by the failure or recovery of the pituitary gland, which usually causing further hypopituitarism and hormone recovery. In order to prevent the potential applications of adrenal cortical malfunction after the surgery, many medical centers will use glucocorticoid supplements during the perioperative period care. However, this treatment might expose the normal hypothalamic-pituitary-adrenal (HPA) axis function patients into potential threats after the treatment of glucocorticoid supplements, such as bone loss, hypertension, emotional distress, and weight gain. To avoid unnecessary supply of glucocorticoids, the key question is to monitor the pituitary function. Thus, in this study we try to predict the morning postoperative cortisol levels, for further prediction of the postoperative pituitary function. To do so, we will review the retrospective charts of transsphenoidal adenomectomied patients from January, 2013 to April, 2018 in the NTUH Taipei. Use statistical methods analyzing all sorts of medical reports, including perioperative hormone thresholds.This study tried to highlight the predictive value of the morning postoperative cortisol levels, which can act as the prognosis value of the postoperative pituitary function, providing future medication advices for improving patients' safety of drugs.
