Endoscopic Detection of Dysplasia in Crohn 's Disease Patient (DYDJI)

Endoscopic Detection of Small Bowel Dysplasia and Cancer in Patients With Jejuna or Ileal Crohn Disease : Prospective Study in a Cohort of High Risk Patients

Patients with Crohn's disease (CD) have an increased risk of small bowel adenocarcinoma (SBA). Long duration of CD is the main risk factor. SB dysplasia has been associated with SBA in 20% of cases, always described in diseased sites. The progression to neoplasia and natural history remains unknown but progression of inflammation to dysplasia and then to adenocarcinoma is suspected. As for surveillance recommendations for colorectal carcinoma in long standing inflammatory colonic disease, endoscopic screening of SB could be proposed in CD patients with risk factors of SBA. No study can be found in literature. The investigators propose a multicenter exploratory open study on prospective cohort of CD patients with high risk of dysplasia or cancer. The goal is evaluate the rate of dysplasia and adenocarcinoma detected by enteroscopy with biopsies in a high risk CD population

dysplasia will be described as high or low level Samples will be analysed by 2 different team of anapathologists

the success will be measured by reaching at least one pathologic area during the endoscopic procedure

Inclusion Criteria: More than 18-years-old Crohn disease on jejunum and/or ileum since at least 10 years Radiography done during last year Exclusion Criteria: Dysplasia previously detected Pregnancy
