Background And Aims: Primary lung tumors (PLTs) in children are rare, and surgery remains the key to ensure remission. Here we describe the PLTs clinical characteristics, their management, and the pulmonary outcome following surgery.

Methods: We carried out a French national cohort of pediatric PLTs from 2013 to 2023 from the FRACTURE rare pediatric tumors national database.

In pediatric thoracic surgery, reported predictors for increased risk are symptoms and active/previous infections (RAP). We investigated the adverse events related to Video-Assisted Thoracic Surgery (VATS) in pediatric patients when considering RAP predictors. A retrospective analysis of pediatric VATS major lung resections in 2008-2021 was conducted at three institutions.

Article Synopsis
  • Short Bowel Syndrome (SBS) is a significant cause of intestinal failure in children, and this study evaluates the long-term outcomes of the surgical technique called serial transverse enteroplasty (STEP) used to treat it.
  • The study involved a review of 36 children who underwent STEP between 2000 and 2022, examining their medical histories, surgical details, and nutritional support.
  • Results showed an increase in bowel length and a decrease in dependency on parenteral nutrition, with many children experiencing improved digestive symptoms and growth after the procedure, indicating STEP can be a beneficial option for managing SBS in children.

Background: Anastomotic stenosis after pull-through surgery remains a challenge in the management of Hirschsprung disease. Based on the management of esophageal stenosis, we evaluated the efficacy of combined radial incision and steroid injection for the treatment of refractory colorectal anastomotic stenosis after pull-through.

Impact Of Innovation: Combined radial incision and steroid injection is an alternative conservative treatment of refractory anastomotic stenosis after pull-though for Hirschsprung disease, avoiding a potential complicated redo pull-though surgery.

While sickle cell anemia (SCA) and hereditary spherocytosis (HS) share common features of increased spleen erythrophagocytosis due to increased red blood cell (RBC) turnover, SCA is specifically characterized by susceptibility to infections. In this study, histological lesions in the spleens of pediatric patients with SCA were analyzed, in close correlation with past clinical history and comparatively to HS, healthy and transfused β-thalassemia patients (TDT). An evaluation of red pulp elementary lesions (red pulp fibrosis, iron deposition, number of Gandy-Gamna, and RBC trapping) combined into a severity score was established, as well as B-cell follicles analysis.

Article Synopsis
  • The study looked at whether children with a condition called esophageal achalasia are at a higher risk of a serious problem (esophageal perforation) if they get a procedure called endoscopic dilatation before a different surgery called Heller myotomy.
  • Researchers checked the results from 77 children who had the Heller myotomy between 2000 and 2022, and found that it didn’t matter if they had the dilatation before; the risk of esophageal perforation was the same.
  • They discovered that the only real risk factor for complications after the surgery was if the doctors caused a tear in the esophagus during the procedure.

Background: Staged laparoscopic management of intra-abdominal testes using pedicular section is recognized as gold standard technique, successful in 85 % of cases for scrotal testicular position with less than 10 % testicular atrophy. Recently, Shehata proposed a new technique without pedicular division for these testes, using spermatic vessels traction, but did not provide a comparative study of the two techniques.

Objective: To evaluate the laparoscopic spermatic pedicular traction (Shehata technique, ST) for the treatment of intra-abdominal testis, as an alternative to gold standard pedicular section (2-stage Fowler-Stephens, FS).

Objectives: Necrotizing enterocolitis (NEC) is a severe neonatal surgical condition, associated with a prolonged pro-inflammatory state, leading to high mortality and morbidity rates. Carbon dioxide (CO ) insufflation during laparoscopy may have an anti-inflammatory effect. We aimed to evaluate the effects of CO -insufflation on experimental colitis.

Article Synopsis
  • Same-day discharge after cholecystectomy is becoming common in both adults and children, yet there's a gap in teaching models for pediatric procedures; this study aimed to evaluate clinical outcomes using an Enhanced Recovery After Surgery (ERAS) protocol for pediatric patients undergoing laparoscopic cholecystectomy.
  • Implemented in 2015, the ERAS pathway focused on optimizing various aspects of surgery, such as admission, anesthesia, and postoperative care, with clear guidelines on when day-case surgery was unsuitable due to specific medical conditions.
  • Among 33 pediatric patients analyzed from 2015 to 2020, only one intraoperative complication occurred, with 9% needing an overnight stay, while no significant postoperative issues were reported, highlighting

Gastrocolic fistulas are very rare in children and their association with Helicobacter pylori is poorly described. We present the case of a 10-year-old boy with a history of chronic abdominal pain, diarrhea, halitosis, and growth delay diagnosed with H. pylori-associated gastritis and gastrocolic fistula.

Article Synopsis
  • * Associated syndromes include trisomy 21 and Mowat-Wilson syndrome, with genes like RET and EDNRB linked to the disease's occurrence.
  • * Diagnosis involves imaging and biopsy, and treatment usually requires surgical removal of the affected bowel, with various surgical techniques available and ongoing research aimed at improving diagnosis and patient outcomes.

Objectives: The objective of this study is to determine whether jejunal nutrition by gastrojejunal tube (GJT) could be a therapeutic option for refractory gastroesophageal reflux disease (GERD), avoiding further antireflux surgery.

Methods: A monocentric retrospective study was conducted for all children <18 years who underwent GJT placement to treat GERD. We collected data at the first GJT placement, 5 months after last GJT withdrawal, and at the end of the follow-up (June 2021).

The aim of this study was to compare outcomes of laparoscopic and robotic-assisted colectomy in children. All children who underwent a colectomy with a laparoscopic (LapC) or robotic-assisted (RobC) approach in our institution (January 2010-March 2023) were included. Demographics, surgical data, and post-operative outcomes within 30 days were collected.

Background: Advances in surgical and neonatal care have led to improved survival of patients with œsophageal atresia (OA) over time. Morbidity remains significant, with one-third of patients being affected by a postoperative complication. Several aspects of management are not consensual, such as the use of œsophagogram before starting oral feeding.

In children with sickle cell anemia (SCA), early splenic complications can require splenectomy, but the benefit-to-risk ratio and the age at which splenectomy may be safely performed remain unclear. To address this question, we analyzed the rate of post-splenectomy events in children with SCA splenectomized between 2000-2018 at the Robert Debré University Hospital, Paris, France. A total of 188 children underwent splenectomy, including 101 (11.

Background: Congenital pulmonary airway malformation (CPAM) is the most common pulmonary malformation. It can be managed via thoracoscopic lobectomy, which is safe and advantageous over thoracotomy. Some authors advocate the need for early resection to get an advantage over lung growth.

Introduction: In 2015, a protocol including early laparoscopy-assisted surgery in the treatment of necrotizing enterocolitis (NEC) was implemented at our institution. Carbon dioxide insufflation during laparoscopy may have an anti-inflammatory effect. We aimed to compare post-operative outcome after early laparoscopy-assisted surgery and classical laparotomy for NEC.

Consensus on the optimal management of asymptomatic congenital pulmonary airway malformation (CPAM) is lacking, and comparison between studies remains difficult due to a large variety in outcome measures. We aimed to define a core outcome set (COS) for pediatric patients with an asymptomatic CPAM. An online, three-round Delphi survey was conducted in two stakeholder groups of specialized caregivers (surgeons and non-surgeons) in various European centers.
