Esophageal Atresia
Esophageal atresia with or without tracheaoesophageal fistula is the most frequent digestive malformation (1 in 2,500 Births). Surgery is mandatory at birth and saves the life of the children. Despite a major improvement in the survival rate of patients, the morbidity associated with these congenital anomalies remains high. Late complications and long term consequences may occur and require long term follow up until adulthood.
We have built a network involving academic centers in Quebec (I currently serve as President of the RQAO, www.rqao.ca) and all around the world (INoEA). These networks, funded by private donations have permitted to carry out projects with large cohorts. A genetic data base is also ongoing with the Réseau de Médecine Génétique Appliquée. The primary objective is to improve the knowledge on the natural history of patients with esophageal atresia, the most frequent GI tract malformation (1 in 2,500 births) from birth to adulthood by organizing the follow-up of the entire cohort operated in Quebec. A large clinical and genetic database is collected.
Subsequent to the increase in survival, short and long term morbidity associated with esophageal atresia repair have become important issues in the management of these children.
Hereafter are some examples of the studies conducted by our group in the Esophageal Atresia Clinic at Ste Justine Hospital:
- Characterization of Esophageal Motility following Esophageal Atresia Repair using High-Resolution Esophageal Manometry
- Abnormal Esophageal Motility in Patients with Isolated Tracheoesophageal Fistula
- Vascular Anomalies Associated With Esophageal Atresia and Tracheoesophageal Fistula
- Congenital Esophageal Stenosis Associated with Esophageal Atresia
- Endoscopic Assessment of Children with Esophageal Atresia: Lack of Relationship of Esophagitis and Esophageal Metaplasia to Symptomatology
- Association of Gastric Heterotopic Pancreas and Esophageal Atresia in Children
- Topical mitomycin-C application in recurrent esophageal strictures after surgical repair of esophageal atresia
- Mucosal bridge as a cause of dysphagia after surgery for esophageal atresia
- Risk factors for short and long term morbidity in children with esophageal atresia
Réseau Québécois interuniversitaire d'étude de l'Atrésie de l'Oesophage (Quebec Network on Esophageal Atresia)
Esophageal atresia is the most common congenital digestive malformation, affecting one in 3,000 newborn babies at birth (i.e. 20 to 25 babies each year in the Province of Quebec). The overall mission of the network is to coordinate treatment for patients at all stages of life in order to optimize care and prevent the morbidity associated with complications occurring during follow-up.
To achieve this, the network offers affected patients the joint multidisciplinary expertise of university tertiary pediatric centres and university adult centres involved in the treatment of esophageal atresia.
International Network Of Esophageal Atresia
Esophageal atresia is the most frequent digestive malformation occurring in ~1:3,000 births worldwide. Since the first successful primary repair in 1941, postoperative outcomes have changed. With the exception of patients suffering from severe associated malformations, improvements in operative and perioperative care issues evolved from mortality to morbidity and quality of life issues. Esophageal atresia is no more a neonatal surgical problem but a long life problem. Indeed, respiratory problems, nutritional and gastroenterological issues are the most prevalent not only in the first years of life but also in adolescence and adulthood. Two previous international meetings on esophageal atresia held in Lille, France in 2010 and in Montreal, Canada in 2012 putting together multidisciplinary teams dedicated to the care of EA patients all over the world have showed the necessity of a systematic approach of these patients. Following these events an International Network Of Esophageal Atresia (INoEA) was created in February 2013 whose ambition is to enhance international collaboration regarding esophageal atresia.
