E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Compare the number of dilations required to maintain a dysphagia score 0-1, during a 12 months period in patients trearted with triamcinolone in comparison with placebo.
|
Comparar o número de dilatações necessárias para manter um grau de disfagia de 0 ou 1, num período de 12 meses, em doentes que recebem triamcinolona vs placebo.
|
|
E.2.2 | Secondary objectives of the trial |
To evaluate the efficacy of with triamcinolone in comparison with placebo in what regards:
- Compare the dysphagia grade at 2 weeks after the first esophageal dilation;
- Compare the mean time between first and second dilation, to maintain a dysphagia grade 0-1;
- In patients submitted to 3 dilations with injection, compare the mean time between the third and the fourth dilation and the grade of dysphagia 3 weeks after the third dilation;
- Compare the mean time between dilations, in the period of 12 months, to maintain a dysphagia grade of 0-1.
|
- Comparar o grau de disfagia às 2 semanas após 1 dilatação esofágica com injecção de triamcinolona vs placebo;
- Comparar o tempo médio entre a 1ª e a 2ª dilatação, para manter um grau de disfagia de 0 ou 1, em doentes que recebem triamcinolona vs placebo;
- Nos doentes que fizerem 3 dilatações com injecção, comparar o tempo médio entre a 3ª e a 4ª dilatações e o grau de disfagia 2 semanas após a 3ª dilatação;
- Comparar o tempo médio entre dilatações, num período de 12 meses, para manter um grau de disfagia de 0 ou 1 em doentes que recebem triamcinolona vs placebo.
