Abstract:Objective To investigate the long-term outcome of adrenalectomy for patients with primary hyperaldosteronism (PHA). Methods All patients with PHA and adrenalectomy from 2001 to 2011 were identified. Charts and follow-up data were reviewed for clinical parameters and hormone levels. Univariate and multivariate analyses were performed with SPSS 19.0. Results A cohort of 30 female and 24 male patients underwent laparoscopic adrenalectomy. Twenty patients (37%) were cured without any further need of antihypertensive medication, 20 (37%) patients experienced an improvement in hypertension, and 14 (26%) patients remained unaffected. Consequently, hypertension was resolved or improved in 40/54 (74%) patients. At final follow-up after a mean of (49 ± 12) months, resolution of hypertension was observed in 27/46 (58%) patients. Interestingly, in 7 patients a period longer than 12 months was required before a resolution of hypertension was observed. Coexistent adrenal hyperplasia, which was observed in 30% of the patients, did not correlate with the outcome. Conclusions In 58% of patients with PHA, hypertension is resolved after laparoscopic adrenalectomy, but the process may require more than 12 months. Coexistent hyperplasia in the resected adrenal gland is not associated with persistent hypertension.
