Synchronous bilateral adrenalectomy for Cushing's syndrome: laparoscopic versus posterior retroperitoneoscopic versus robotic approach.

Background: Synchronous endoscopic bilateral adrenalectomy (BilA) can effectively provide definitive cure of hypercortisolism in ACTH-dependent Cushing's syndrome and in primary adrenal bilateral disease. We compared three different approaches for BilA: transabdominal laparoscopic BilA (TL-BilA), simultaneous posterior retroperitoneoscopic BilA (PR-BilA), and robot-assisted BilA (RA-BilA).

Methods: All patients who underwent BilA between January 1999 and December 2012 at two referral centers (one performing TL-BilA and PR-BilA and one performing RA-BilA) were included.
