Brief Summary:


To determine the metabolic effects of the adrenalectomy in subclinical Cushing's syndrome of adrenal incidentaloma.


234 subclinical cushing syndrome and adrenal incidentaloma will be randomly assigned into two groups(e.g adrenalectomy group and conservative treatment group).

Condition or disease Intervention/treatment Phase
Cushing Syndrome Procedure: surgery Not Applicable

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 234 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Long-term Effects of Adrenalectomy on Metabolic Syndrome, Glucose Metabolism, Lipid Metabolism, and Bone Metabolism in Subclinical Cushing's Syndrome of Adrenal Incidentaloma
Study Start Date : May 2011
Estimated Primary Completion Date : May 2018
Estimated Study Completion Date : May 2018

Arm Intervention/treatment
Active Comparator: Adrenalectomy group
patients who undergo adrenalectomy
