Safety and Feasibility of Laparoscopic Resection of Neuroblastoma Without Image-Defined Risk Factors Performed by...

Laparoscopic resection has gradually been adopted for neuroblastoma patients; however, some authors reported that, due to its technically demanding procedures, this operation should be performed only by highly experienced surgeons. The aim of this study was to evaluate the safety and feasibility of laparoscopic resection of abdominal neuroblastoma by pediatric surgical trainees. In this multicenter, retrospective study, including 18 children with abdominal neuroblastoma indicated for 19 laparoscopic resections (1 with bilateral neuroblastomas) from 1999 to 2018, the clinical data were retrospectively reviewed and compared between trainee and attending surgeons. None of the cases had image-defined risk factors (IDRFs) at surgery. All patients successfully underwent complete laparoscopic resection without blood transfusion, open conversion, or intraoperative or postoperative complications. Of the 19 cases, 6 were performed by pediatric surgical trainees under the guidance of attending surgeons, and 13 were performed by attending surgeons. With comparable tumor, largest diameter, operative time, and bleeding amount were not significantly different between the two groups. In the trainee surgeon group, one local recurrence occurred at a secondary resection site in the bilateral neuroblastoma patient with Stage L2. Laparoscopic resection of neuroblastoma could be safe and feasible when limited to absent IDRFs at surgery by pediatric surgical trainees under the guidance of experienced attending surgeons, as well as by attending surgeons.
