Reoperative adrenal surgery: lessons learnt

With the widespread use of abdominal imaging, the detection and therefore incidence of adrenal tumours is increasing. The laparoscopic approach to primary surgical resection of adrenal tumours has now become the standard of care. There is scarce published literature regarding the management and outcomes of recurrent adrenal tumours. The aim of the present study was therefore to review the authors' experience with reoperative adrenal surgery. A retrospective review of reoperative adrenalectomy cases identified from the prospectively maintained University of Sydney Endocrine Surgical Unit Database from January 1988 to July 2007 was carried out. There were nine (3.5%) reoperative adrenalectomies in six patients. Two were cases of adrenocortical carcinoma, two involved cases of familial phaeochromocytomas and two cases were due to sporadic phaeochromocytomas. Reoperative adrenal surgery is an uncommon event. During the index surgery for adrenal tumours, all adrenal tissue should be removed and knowledge of the vagaries of adrenal anatomy is essential. Reoperative adrenal surgery is a safe procedure and may confer survival benefit or symptom relief. Lifelong follow up is essential for all patients who have had surgery for functional and malignant adrenal tumours.
