Microscopic versus endoscopic transsphenoidal surgery in the Leiden cohort treated for Cushing’s disease: surgical outcome, mortality, and complications

We compared both techniques for the treatment of Cushing’s disease at the Leiden University Medical Center, a European reference center for pituitary diseases.
