19 laparoscopic unilateral adrenalectomies were performed in 10 girls and 7 boys (mean age 3.9 years) during 1998-2011. The clinical diagnosis before surgery was virilizing tumor (n?=?8), pheochromocytoma (n?=?3), nonfunctioning solid adrenal tumor (n?=?3), mixed adrenocortical tumor (n?=?2), cystic adrenal mass (n?=?1). Unilateral adrenal lesions were 20-65?mm at the longest axis on computerized tomography (12 right side, 7 left side).
The final clinicopathological diagnosis was cortical adenoma (n?=?9), pheochromocytoma (n?=?3, bilateral in two), neuroblastoma (n?=?1), ganglioneuroblastoma (n?=?1), ganglioneuroma (n?=?1), adrenocortical carcinoma (n?=?1), benign adrenal tissue (n?=?1). Average operative time was 138.5?min (range 95-270). Blood transfusion was required in one case (5 % ). No conversion to open surgery was required and no deaths or postoperative complications occurred. Average hospital stay was 3.5 days (range 2-15). Average postoperative follow-up was 81 months (range 2-144). Two contralateral metachronic pheochromocytomas associated with von Hippel-Lindau syndrome occurred, treated with partial laparoscopic adrenalectomy (one without postoperative need of cortisone replacement therapy).
Laparoscopic adrenalectomy is a feasible procedure that produces good results. It can be used safely to treat suspected benign and malignant adrenal masses in children with minimal morbidity and short hospital stay.
