Abstract

Purpose: To analyze the role of laparoscopic surgery for the management of pediatric adrenal tumors (AT).

Methods: Retrospective analysis of children diagnosed with AT, operated laparoscopically during 2003-2020. The strategy differed according to tumor extension. AT < 6 cm were resected. Locally advanced tumors (L2) or > 6 cm were biopsied.

Results: N = 28. Complete tumor resection (R0) in 20 (71%), tumor biopsy in 8 (R2). Age (median): 28.8 months (2 months-18 years). 14/28 left-sided, 2 bilateral. Median operating time: 78 min (45-180). Mean tumor size (for resections): 4 cm (2.5-6). Tumor pathology: neuroblastoma (n = 17), Ganglioneuroma (n = 7), Adrenocortical carcinoma (n = 1), Osteosarcoma metastasis (n = 1), Pheochromocytoma (n = 1), Venous malformation (n = 1). Mean hospital stay: 2.5 days (1-3). Mean follow up: 65.5 months (24-192). Overall survival and event-free survival were 86 and 75%, respectively (5 years event-free survival for neuroblastoma: 33% [intermediate risk], 16.6% [high risk]. No surgery-related mortality.

Conclusion: Laparoscopic surgery for adrenal tumors is safe. Laparoscopic biopsy is useful for unresectable tumors when a percutaneous approach is not possible. With the proposed selection criteria, the laparoscopic approach should be the first option for resection of small and localized AT in pediatrics.
