Endoscopic Cholecystoduodenostomy With Lumen-Apposing Metal Stent for Bile Duct Stricture in a Child with Neuroblastoma: A Case Report.

We report the use of endoscopic cholecystoduodenostomy in a 6-year-old child to manage postanastomotic stricture of the common bile duct (CBD) secondary to an intraoperative injury sustained during the resection of an abdominal neuroblastoma (NB). The patient was diagnosed with stage M NB, characterized by dissemination to the bone marrow and vertebrae, and MYCN amplification. Following multiple cycles of chemotherapy and subsequent hematopoietic stem cell transplantation, the patient was scheduled for surgical resection.

Development of a New Score Based on Image Defined Risk Factors to Standardize Surgical Risk in Neuroblastoma Resection - A SIOPEN Collaborative Study.

Background And Aims: Image Defined Risk Factors (IDRFs) assess surgical risk in neuroblastoma (NB) and guide neoadjuvant therapy. Despite chemotherapy IDRFs may persist in 70 % of cases. Several studies have suggested that not all IDRFs hold equal significance and that the presence of an IDRF does not inherently signify unresectability.

Exploring the frontier in robotic pediatric cancer surgery: when to move forward and when to stop.

Purpose: In recent years, the use of robotic-assisted minimally invasive surgery in pediatric oncology has increased. Despite its benefits, its adoption remains limited. This single-center retrospective analysis examines technical nuances, indications, and surgical limitations to prevent complications.

Pediatric nutritional surgery and its implications: results from a unicentric retrospective analysis.

Purpose: Existing guidelines provide weak recommendations on the surgical management of nutritional problems in children. The objective was to design a management pathway to address the best nutritional surgery (NS) procedure in a given patient.

Methods: Retrospective analysis of children treated at our department from January 2015 to December 2019.

Laparoscopic ovarian tissue collection for fertility preservation in children with malignancies: a multicentric experience.

Introduction: Long survivors after childhood cancer are increasing thanks to oncological improvements. Their quality of life and fertility-sparing should be considered in the early phases of each oncological pathway. Cryopreservation of ovarian tissue removed before starting gonadotoxic therapies is the only fertility sparing procedure available for prepubertal children affected by cancer and it does not affect the timing of the start of the treatment.

Posterior Tracheopexy for Tracheomalacia: A Study of Clinical and Radiological Consequences on Esophagus.

Introduction:  Posterior tracheopexy (PT) directly addresses the posterior trachealis membrane intrusion in severe tracheomalacia. During PT, the esophagus is mobilized and membranous trachea is sutured to the prevertebral fascia. Although dysphagia has been reported as a possible complication of PT, in the literature there are no data investigating postoperative esophageal anatomy and digestive symptoms.

Surgical validation of functional magnetic resonance urography in the study of ureteral anomalies distal to the uretero-pelvic junction in a pediatric cohort.

Background: Ureteral anomalies distal to the uretero-pelvic junction (UPJ) belong to the wide spectrum of congenital anomalies of the kidney and urinary tract (CAKUT). They can cause severe obstruction requiring a detailed anatomical depiction to define the surgical approach. Up to date, ultrasonography, voiding cystourethrography and scintigraphy are considered the gold-standard diagnostic tools to study obstructive anomalies of the urinary tract; however, they do not provide accurate ureteral anatomical details.

Complications and trends in minimally invasive repair of pectus excavatum: A large volume, single institution experience.

Background/purpose: Complication risk in minimally invasive repair of pectus excavatum (MIRPE) is not negligible, particularly during learning curve. We reviewed the complications of a large series, evaluated the correlation with technical details and learning curve, and presented the strategies implemented to reduce them.

Methods: Data on MIRPE patients from 2005 to 2020 (divided in two groups: before and after 2013) were collected prospectively and reviewed.

Safety of Veress needle for laparoscopic entry in children: Myth or reality?

Introduction: Recent reports suggested that blind laparoscopic entry techniques, including Veress needle (VN), might increase the risks of potentially fatal complications.

Materials And Methods: All consecutive patients who underwent laparoscopy in two Pediatric Hospitals with the use of a Veress needle during a 14-year period have been included. In all cases the first trocar was a radially expanding one (STEP).

Non-standard approach to infants and children with megacolon: laparotomy and endorectal pull-through for diagnosis and treatment in difficult countries with low resources in a non-profit setting: return to the past Soave's ERPT.

Background: Hirschsprung's disease is an important cause of pediatric constipation with high risk of bacterial enterocolitis. Its diagnosis is histological and the suction biopsy is the gold standard. In resource-limited countries, the main diagnostic exam is the contrast enema and mini-invasive surgery lacks.
