Use of Radioguided Surgery for Small and Difficult-to-Locate Relapsed MIBG (+) High-Risk Neuroblastoma Lesions.

Introduction: High-risk neuroblastoma, particularly in the relapse/refractory (R/R) setting, poses unique challenges to obtaining the representative-quality tissue that is mostly required for molecular analysis. This study explores the use of 123I-MIBG radioguided surgery to access complex locations of MIBG-positive neuroblastoma as a tool to overcome the difficulties associated with repeated surgeries in these patients.

Methods: This study is a retrospective review of all patients with R/R neuroblastoma and MIBG-uptaking lesions who underwent radioguided surgery between February 2020 and 2023 at SJD Barcelona Children's Hospital.

Current Status of Fertility Preservation in Pediatric Oncology Patients.

Cancer poses significant emotional challenges for children and adolescents, despite improvements in survival rates due to new therapies. However, there is growing concern about the long-term effects, including fertility issues. This review examines recent advancements and future directions in fertility preservation within a pediatric population subjected to oncological therapies.

Anastomosis near to the ileocecal valve in neonates with focal intestinal perforation, is it safe.

Background: Anastomosis near the ileocecal valve (ICV) are controversial due to the increased pressure on the suture; in this situation, the valve could be removed at a first stage or at the moment of stoma closure. However, preservation of the ICV has proved important benefits in the long term. The aim of this study is to evaluate its feasibility in neonates with focal intestinal perforation (FIP).

Results of Ovarian Sparing Surgery in Pediatric Patients: Is There a Place for Laparoscopy?

Laparoscopy is widely accepted for the surgical treatment of benign ovarian lesions in adult women, with results similar to an open approach when spillage is avoided by different means such as endobag retrieval. This approach is controversial in children. Retrospective study (2009-2018) of all pediatric ovarian tumors with histological confirmation treated in a tertiary center.

Management of neonates with right-sided aortic arch and esophageal atresia: International survey on IPEG AND ESPES members´ experience.

Aim: The optimum surgical approach of neonates with right-sided aortic arch (RAA) and esophageal atresia (EA)/tracheoesophageal fistula (TEF) is still an unsolved question. In order to propose an operative algorithm in the era of endoscopic surgery, we performed an international survey to know the current practice between pediatric endoscopic surgeons. Two of the most important societies in endoscopic pediatric surgery were queried: the International Pediatric Endosurgery Group (IPEG) and the European Society of Paediatric Endoscopic Surgeons (ESPES).
