RESUMO
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.

Introduction: Thoracoscopic repair of congenital diaphragmatic hernia (CDH) has become a popular approach and several benefits have been published. Patch closure requires demanding thoracoscopic skills and therefore primary closure with tight sutures is often pursued, which increases the risk of recurrence. The purpose of this study was to create and assess the performance of a new technique for thoracoscopic repair of CDH, which facilitates the surgical procedure. Materials and Methods: An innovative system for thoracoscopic repair of CDH with a novel patch was developed. The patch is self-expandable and offers a traction suture for stabilization, isolating and protecting the viscera. Its performance was assessed and compared with a conventional patch in an inanimate model of the disease through a quantitative and qualitative multivariate analysis. Results: Nine cases of CDH were repaired with each patch. The duration of the procedure was shorter (P < .05) and the level of difficulty was reported to be lower (P < .001) when using the self-expandable patch (SeP). The number of good quality knots was higher and adverse events were less common with this new technique. Conclusions: The stabilizing SeP offers safe and ergonomic performance for thoracoscopic CDH repair, facilitating the surgical technique. The main advantage is that it keeps the viscera isolated into the abdomen while offering a flap on the thoracic side for suturing in a practical manner, minimizing the risk of visceral injury and saving surgical time.
