Abstract | BACKGROUND: METHODS: RESULTS: Sixty-two patients with hyperaldosteronism underwent laparoscopic adrenalectomy in the period from December 1995 to August 2005. The median follow up was 59 months. There was a significant decrease in both systolic blood pressure and diastolic blood pressure at final follow up compared with that before operation. Systolic blood pressure decreased from 149 mmHg to 129 mmHg at final follow up (P < 0.0001). Diastolic blood pressure decreased from 89 mmHg to 80 mmHg (P < 0.0001). Antihypertensive requirement was decreased from an average of 2.6 separate medications preoperatively to 1.4 medications at final follow up (P < 0.0001). Serum aldosterone levels were significantly lower (698 (confidence interval 534-862) pg/mL vs 181 (confidence interval 139-225) pg/mL, P < 0.0001). Overall, 34% of patients had cure of hypertension and did not require any antihypertensive agent. A further 51% had improvement in BP control, whereas 5% had no change or had worsening hypertension. Multivariate regression analysis showed that age and gland size were independent factors predicting sustained hypertension after surgery. CONCLUSION:
