HOW I DO IT: Cushing's disease-selective adenomectomy via an endoscopic transsphenoidal approach

1Leeds General Infirmary, Leeds, UK.
Background:
An ACTH-secreting pituitary adenoma is the most common cause of excessive endogenous glucocorticoid production resulting in Cushing's Syndrome. A multidisciplinary approach is paramount. Selective adenomectomy is the treatment of choice.
Method:
Endoscopic transnasal transsphenoidal approach to the tumour, along with techniques for resection, are demonstrated.
Conclusion:
Endoscopic transsphenoidal approaches with its magnified view of the pituitary gland allows precise microsurgical dissection during selective adenomectomy. This technique increases the possibility of proving a gross total resection, leading to clinical and biochemical cure in these patients.
