Abstract
CONTEXT
Management of congenital adrenal hyperplasia (CAH) involves suppression of the hypothalamic-pituitary-adrenal axis using supraphysiological doses of exogenous glucocorticoids. This can pose a challenge, with Cushing syndrome a frequent complication of adequate suppression. Bilateral adrenalectomy, with subsequent replacement of glucocorticoids and mineralocorticoids at physiological doses, has been proposed as an alternative therapeutic strategy.
OBJECTIVE
To review the outcomes after bilateral adrenalectomy for CAH.
DATA SOURCES
A systematic search of PubMed/MEDLINE and Web of Science, identifying relevant reports published up to 10 January 2018.
STUDY SELECTION
Case reports or case series were included if they reported individual patient data from patients with CAH who had undergone bilateral adrenalectomy.
DATA EXTRACTION
Information regarding the following was extracted: first author, country, sex, age at adrenalectomy, year of adrenalectomy, diagnosis, molecular abnormality, pre- and postoperative biochemistry, pre- and postoperative medications, pre- and postoperative body mass index, indication for adrenalectomy, surgical technique, gross and microscopic adrenal characteristics, follow-up duration, and short- and long-term postoperative outcomes.
DATA SYNTHESIS
We identified 48 cases of bilateral adrenalectomy for CAH, with patients aged from 4 months to 56 years at surgery. The most common indication for surgery was the inability to control hyperandrogenism/virilization and/or Cushing syndrome (n = 30; 62%). Most patients (n = 34; 71%) reported symptomatic improvement postoperatively, with some cases of short-term (n = 5; 10%) and long-term (n = 13; 27%) adverse outcomes.
CONCLUSIONS
Bilateral adrenalectomy for CAH appears to be a reasonable therapeutic option for carefully selected patients who have had unsatisfactory outcomes with conventional medical management.
