E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
evaluate whether intralesional injection with steroids in children with EA can prevent the development of a refractory stricture, and thus can minimize the total number of dilatations within 28 days interval. |
évaluer si l’injection intralésionnelle de stéroïdes chez les enfants atteints d’EA peut prévenir le développement d’une sténose éfractaire et ainsi réduire le nombre total de dilatations dans un intervalle de 28 jours. |
|
E.2.2 | Secondary objectives of the trial |
- compare between the two groups the level of dysphagia and the child’s eating behavior at the end of the follow up period. - compare between the two groups the efficacy of dilatation with or without intralesional steroid injections on the luminal diameter and the stricture length. - evaluate a possible influence of co-medication (e.g. antacids) on stricture formation. - analyze the possible systemic effects of a one-time intralesional steroid injection. - analyze the cost-effectiveness of the use of intralesional steroid injections to prevent refractory strictures. |
- comparer entre les deux groupes le niveau de dysphagie et le comportement alimentaire de l’enfant à la fin de la période de suivi. - comparer entre les deux groupes l’efficacité de la dilatation avec ou sans injections intralésionnelles de stéroïdes sur le diamètre luminal et la longueur de la striction. - évaluer l’influence possible de la co-médication (p. ex., antiacides) sur la formation de strictures. - analyser les effets systémiques possibles d’une injection unique de stéroïdes intralésionnels. - analyser la rentabilité de l’utilisation d’injections intralésionnelles de stéroïdes pour prévenir les sténoses réfractaires. |

E.5.2 | Secondary end point(s) |
1) Total number of dilatations within the study period, regardless of the interval. 2) Interval (in weeks) between the start of the study and the last dilatation procedure within the study period. 3) Montreal Feeding Scale (in Dutch Screeningslijst Eetgedrag Peuters (SEP)), measured at the end of the follow up period. 4) The relative change in maximal luminal diameter after the 3rd dilatation compared to the diameter before the 3rd dilatation. 5) The use of co-medication (e.g. antacids) during the study period. 6) The mean cortisol level over the first three months after the 3rd dilatation, measured in a hair sample taken at the end of the follow up period. 7) Total costs of the treatment, including medical and non-medical costs.
