AB191. Laparoscopic subcutaneous transposition of a pedicled adrenal for ACTH-independent bilateral macronodular adrenal hyperplasia

Objective: Bilateral adrenalectomy or unilateral adrenalectomy and contralateral partial adrenalectomy are indicated for the treatment of ACTH-independent macronodular adrenal hyperplasia. Independent of the surgical procedure, the prognosis is poor. This paper discusses a new treatment method and its efficacy for treating nodular adrenal hyperplasia.

Methods: We performed a retrospective review of the medical records of 12 patients operated on between January 2008 and October 2014 at the First Affiliated Hospital of Zhengzhou University. All patients were treated by laparoscopic subcutaneous transposition of a pedicled adrenal. We performed postoperative monitoring of patients including clinical symptoms and 24-hour levels of serum free and urinary free cortisol.

Results: All twelve patients were pathologically confirmed to have nodular adrenal hyperplasia, and were followed for an average of 45.5 months (range, 24–60 months). The clinical symptoms of all patients disappeared, and the 24-hour plasma free cortisol and urinary free cortisol levels were within the normal range.

Conclusions: Laparoscopic subcutaneous transposition of a pedicled adrenal is a new and effective method for treating bilateral macronodular adrenal hyperplasia, and can achieve long-term remission of Cushing’s syndrome.
