Laparoscopy or retroperitoneoscopy for pediatric patients with adrenal masses?

Minimally invasive approach to the adrenal gland was first reported in 1992. Since then, the experience with the laparoscopic technique for adrenal disease in children has been limited. We report our experience with minimally invasive adrenal surgery in children. Two young girls (2 and 4 years old) with a left adrenal mass were operated using minimally invasive surgery (MIS) in our Unit. Ultrasonography and MRI showed in the oldest a 2x3 cm adrenal mass, while in the youngest a 5.5x5 cm adrenal tumor was found. According to the pre-existing literature, we approached the smallest lesion via retroperitoneoscopy, and the largest one laparoscopically. The operating time was 110 minutes for retroperitoneoscopy and 75 minutes for laparoscopy. No major intra or postoperative complications occurred. There were no conversions to open surgery. Postoperative hospital stay was 5 days for both patients. In both cases, the anatomopathological result was an adenoma. Minimally invasive adrenalectomy is a safe and feasible procedure in children with good results. For lesions smaller than 3-4 cm retroperitonescopy is feasible, while for tumors larger than 5 cm, due to malignancy risk, the laparoscopic approach is indicated. To keep oncologic criteria it is important to avoid tumor rupture and to extract the specimen in an endobag.
