Methods: This retrospective study included trainees enrolled in the IAD_PLSC program in 2021 and 2022 which included two separate 12 h-sessions.

Recurrence of vesico-ureteral reflux in children: is still the endoscopic injection the best option?

Background: Endoscopic injection (EI) is a safe treatment for vesico-ureteral reflux (VUR) in children, but recurrences are not insignificant. This study aims to show if multiple EI is still the best first line management even if in case of recurrences.

Methods: All patients affected by primary VUR, treated with at least one EI and with at least 5 years follow up were included.

Laparoscopic Treatment of Wilms' Tumor: Criteria of SIOP-UMBRELLA Protocol may be Updated.

Introduction: Total nephrectomies for the treatment of Wilms' tumor (WT) are more and more performed by laparoscopy, although indications for this approach following the UMBRELLA guidelines are currently very restrictive. The purpose of this study was to assess the compliance to the criteria of the UMBRELLA protocol for minimally invasive approach of WT.

Methods: This retrospective multicenter study included children operated on by laparoscopic total nephrectomy for suspected WT before 2020.

A 16-year bicentric retrospective analysis of ovarian tissue cryopreservation in pediatric units: indications, results, and outcome.

Background: Cancer treatments of the last decades improve the survival rate of children and adolescents. However, chemo- and radiotherapy result in gonadal damage, leading to acute ovarian failure and sterility. The preservation of fertility is now an integral part of care of children requiring gonadotoxic treatments.

Pectus Arcuatum: A Pectus Unlike Any Other.

Background: Pectus arcuatum is often mistaken for a type of pectus carinatum. However, pectus arcuatum is a unique clinical form of pectus caused by premature obliteration of the sternal sutures (manubrial sternum, four sternebrae and xiphoïd process), whereas pectus carinatum is due to abnormal growth of the costal cartilage. In order to better describe pectus arcuatum, we analysed the files of patients with pectus arcuatum followed in our centers.

Anti-reflux surgery in children with congenital diaphragmatic hernia: A prospective cohort study on a controversial practice.

Introduction: Gastro-esophageal reflux disease (GERD) is the most frequent long-term morbidity of congenital diaphragmatic hernia (CDH) survivors. Performing a preventive fundoplication during CDH repair remains controversial. This study aimed to: (1) Analyze the variability in practices regarding preventive fundoplication; (2) Identify predictive factors for fundoplication.

Preoperative 3D reconstruction images for paediatric tumours: Advantages and drawbacks.

Rationale: Three-dimensional reconstruction (3DR) of preoperative images may improve the presurgical assessment of tumours prior to removal. We aimed to analyse the advantages and discrepancies of preoperative 3DR in paediatric tumours.

Methods: We conducted a prospective observational study from 2016 to 2019, including patients with thoraco-abdominal tumours having predictable surgical risks on preoperative images (encasement of vessels posing vascular risks, ie, neuroblastic and soft tissue tumours or parenchyma preservation of the invaded organ, ie, liver and kidney).

Resection of Bronchogenic Cysts in Symptomatic Versus Asymptomatic Patients: An Outcome Analysis.

Background: The natural evolution of bronchogenic cysts (BCs) is unpredictable. Although most surgeons agree that symptomatic BCs should be resected, questions remain regarding the optimal management of asymptomatic mediastinal cysts. We present a case series of BCs to compare patients who underwent preventive operation with those who underwent surgical procedure after symptom onset.

Vanishing Gastroschisis with a Favorable Outcome after a 3-Year Follow-Up: A Case Report and Literature Review.

Vanishing gastroschisis (VG) is a severe complication of gastroschisis with a high mortality rate. We report here a case of VG with a favorable outcome after a 3-year follow-up. A 26-year-old primigravida woman was referred to Strasbourg University Hospital because her fetus was diagnosed with an isolated gastroschisis at 13-week gestation.

Our Laparoscopic Surgical Technique and Experience in Treating Pediatric Inguinal Hernia Over the Past Decade.

Background: Over the past decade, laparoscopic hernia repair was the most performed operation in our department. Equally, it compromises 15% of all pediatric operations performed. We aim, in this study, to review all the cases performed and extrapolate important information like reoccurrences, the incidence of metachronous inguinal hernia, complications amongst other information.

3D imaging and urology: Why 3D reconstruction will be mandatory before performing surgery.

We relate a single-center experience in virtual surgical planning to demonstrate interests and perspectives in pediatric urology. METHOD: From 2004 to April 2017, 4 patients were analyzed before intervention at our institution. All patients had undergone a low dose CT scan.

[Medium and long-term respiratory outcome in patients operated from congenital diaphragmatic hernia: From a series of 56 patients].

Introduction: Recent advances in prenatal diagnosis, high frequency oscillatory ventilation and pulmonary arterial hypertension (PAH) therapies have progressively improved the survival of patients with congenital diaphragmatic hernia (CDH). However, CDH is associated with high morbidity that affects about half of surviving children. The main sequelae observed are respiratory (asthma, persistent PAH [PPAH], bronchopulmonary dysplasia, respiratory infections) and digestive (gastroesophageal reflux disease [GERD]).

Infectious Complications After Laparoscopic Appendectomy in Pediatric Patients with Perforated Appendicitis: Is There a Difference in the Outcome Using Irrigation and Suction Versus Suction Only? Results of a Multicentric International Retrospective Study.

Background: Analyzing the recent literature, it seems that the use of irrigation increases the incidence of intra-abdominal abscesses (IAAs) and infectious complications in perforated appendicitis. The aim of this study was to compare peritoneal irrigation and suction versus suction only during laparoscopic appendectomy (LA) for perforated appendicitis in children.

Materials And Methods: We retrospectively reviewed the records of 699 patients (460 boys and 239 girls, average age 9.

Pediatric thoracoscopic repair of congenital diaphragmatic hernias.

Congenital diaphragmatic hernia (CDH) is a rare congenital disease requiring neonatal surgical treatment. The traditional surgical management of CDH consists of diaphragmatic repair by laparotomy. Thoracoscopic repair techniques have been well described for CDH with late presentation.

Current perspectives in robot-assisted surgery.

From classical surgery to robot-assisted surgery (RAS), there has been a long way allowed by the improvements achieved in minimally invasive surgery (MIS). The last three decades have witnessed a prodigious development of MIS, and especially in the field of laparoscopic pediatric surgery but there are several limitations in the use of conventional laparoscopic surgery and RAS was developed to relieve these drawbacks. This new technology enables today the performance of a wide variety of procedures in children with a minimally invasive approach.

Endoloop versus endostapler: what is the best option for appendiceal stump closure in children with complicated appendicitis? Results of a multicentric international survey.
