Long Term Outcome of Easophageal Atresia : Transmics Profiles in Adolescence

Oesophageal atresia (OAEA), a malformation of the oesophagus present from birth, is characterized by the interruption of the continuity of the oesophagus, which then ends in a cul-de-sac. (Source: Fimatho) An operation is then required to restore continuity to the esophagus. Although this operation enables the vast majority of children to survive the neonatal period, health problems such as gastro-oesophageal reflux, eating difficulties, respiratory problems and growth problems persist throughout life. The aim of the project is to create a prospective cohort of adolescents aged 13/14, nested in the national AO registry. of adolescents born with esophageal atresia, including a biobank of esophageal mucosa and plasma blood samples. Once the clinical and omic data have been collected, the data will be transferred to the France Cohortes information system for analysis, in order to assess the long-term outcome of this rare disease and establish multi-omic profiles. Once the clinical data have been collected and the omics data (derived from analysis of the biobank's biological samples) have been generated, they will be analyzed by the project partners to assess the long-term outcome of OA and establish multiomic profiles. The raw data will be available on the France Cohorte platform.

Brazilian Multicenter Study on Esophageal Atresia

Esophageal atresia is a congenital malformation where the esophagus does not form properly, often associated with a tracheoesophageal fistula. This condition requires complex surgical treatment and intensive neonatal care. Survival has improved worldwide, but results from other countries cannot be directly applied to Brazil due to differences in health resources. This study will gather data from 72 neonatal centers across Brazil to better understand the characteristics, treatments, complications, and outcomes of newborns with esophageal atresia. The goal is to identify factors associated with complications and mortality, and to generate national evidence that can guide better care and improve survival and quality of life.

Balloon Inflation Time for Esophageal Strictures (BITES): A Randomized Multi-Center Study

Esophageal atresia (EA) is one of the most common gastrointestinal congenital anomalies that affects 1 in 2500 to 1 in 4000 live births. It is characterized by abnormal development of the esophagus, which requires surgical intervention to be compatible with life. Surgical repair of EA is associated with risk of developing esophageal strictures or narrowing, which nearly affects 40% of cases. Strictures can be treated using endoscopic balloon dilation, which consists of introducing a catheter with a balloon into the esophagus via endoscopy and positioning it across stricture followed by balloon inflation. The inflated balloon is held in position for a set amount of time with the goal to dilate the narrowed area. At this time there are no pediatric studies comparing difference balloon dilation times and outcomes. Our study's goal is to evaluate balloon dilation inflation time in treating esophageal anastomotic strictures to understand if inflation time is associated with outcome.

Symptoms, Pulmonary Function, Muscle Strength, Exercise Capacity, and Frailty in Esophageal Atresia vs. Healthy Peers

Esophageal atresia is the most common congenital anomaly of the esophagus and is caused by abnormal development of the esophagus during intrauterine life. In children with esophageal atresia, structural abnormalities due to congenital anomalies and tracheoesophageal fistula, tracheomalacia, respiratory problems, recurrent respiratory tract infections, structural abnormalities, surgical interventions for repair and treatment, and decreased physical activity levels may negatively affect pulmonary function, effective coughing, muscle strength, exercise capacity, posture, motor function, and quality of life. This study aims to compare physical characteristics, body composition, pulmonary function and muscle strength, peak cough flow, posture assessment, peripheral muscle strength test, motor function, exercise capacity, physical activity level, fatigue, frailty and quality of life between children with esophageal atresia and their healthy peers.

Transanastomotic Tube for Proximal Esophageal Atresia With Distal Tracheoesophageal Fistula Repair

This trial will compare the effectiveness of two common surgical practices for Type C esophageal atresia repair: esophageal atresia (EA) with distal tracheoesophageal fistula (TEF). Infants with EA/TEF requiring surgical intervention will be recruited. Subjects will be randomized to either repair with or without transanstomotic tube (TT) during esophageal anastomosis creation. Primary outcome is symptomatic anastomotic stricture development requiring dilation within 12 months.

Prospective Evaluation of the Results of Multidisciplinary Follow-up After a Transitional Consultation for Esophageal Atresia

A transition consultation for adult patients with esophageal atresia, involving medical and paramedical stakeholders, was set up at Hôpital Saint-Louis in 2020. The aim of this initiative is to: 1. initiate adult medical, psychological and social follow-up; 2. empower these adults in their future care; 3. establish a personalized follow-up schedule. This project is the first to focus on post-traumatic stress disorder (PTSD) in young adults with esophageal atresia. A 3-year analysis of the somatic and psychosocial variables analyzed will confirm the validity of this initiative, and define its optimal contours for improving these patients' quality of life as adults.
