P303 Role of parietal healing by ultrasound in the evolution of patients with Crohn’s disease

Abstract Background The objective of this study is to assess the degree of parietal involvement with ultrasound and see how they influence the prognosis according to the findings. Methods It was defined as ‘parietal healing’ the normalisation of ultrasound findings in a previously affected segment (parietal thickness less than 3 mm and absence of parietal hyperaemia). Therefore, patients with absence of ultrasound activity but without reaching parietal healing were considered to be those without significant inflammatory signs (parietal thickness
