[Subtotal bilateral adrenalectomy preserving adrenocortical function].
This study analyzed the frequency of recurrence and postoperative adrenocortical function in 16 patients who had been operated on by bilateral subtotal adrenalectomy since 1995. Bilateral pheochromocytoma was found in 13 patients, bilateral adrenal metastases in 2 patients, and bilateral micronodular adrenocortical hyperplasia with primary aldosteronism in 1 patient. An endoscopic approach was performed in four patients. The remaining 12 patients were operated on by an open approach. In ten patients, unilateral subtotal adrenalectomy with contralateral total adrenalectomy (synchronous or metachronous) was performed. Six patients underwent bilateral subtotal adrenalectomy. In all patients, a total of residual adrenal tissue of at least 1/3 of a normal adrenal gland was left in situ. 15 patients were successfully weaned from exogenous steroid substitution. During a mean follow-up period of 24 months, no recurrences were observed. Three patients died without local recurrence. The present study provided evidence for the safety and benefit of subtotal bilateral adrenalectomy, which could guarantee sufficient adrenocortical function in adrenal remnant volume of more than one-third of one adrenal gland even after dividing the main adrenal vein. At our institution, particularly in patients with inherited pheochromocytoma, subtotal adrenalectomy has become a common surgical strategy.
