113 11–14 APRIL, 2018, HELSINKI, FINLAND MATERIAL AND METHODS Retrospective cases from 2012 and June 2017 of patients with adrenal tumors removed by prono retroperitoneoscopy. RESULTS There were 4 patients with a mean age of 12 months (8,6), with solid lesion in adrenal gland with a mean diameter of 3,7 cm (0,49), 3 left 1 right, all of them with diagnosis of neuroblastoma. All pa- tients were positioned fully prone. The retroperitoneal space was created using the Gaur technique, 1 optical port and 2 working ports were used. With blunt dissection and diathermy the adrenal was exposed and the vessels identified, they are individual divided either with clips or a vessel sealing device. The tumor was removed complete with a specimen retrieval system. Mean surgery time was 170 min (30,5). There was one case of capsule rupture, and no reconversions. No postoperative complications. The mean postoperative LOS was 2,3 (0,96) days. All lesions were margin free and none required adjuvant chemotherapy. The mean follow up was 17 months (24,6); there have been no recurrence, and an overall survival of 100 %. CONCLUSIONS Retroperitoneoscopic adrenalectomy is a feasible procedure, in selected cases it can be used to safely treat benign and malignant adrenal masses in children with minimal morbidity and a shorter hospital stay. 08:40–08:52 Discussion
