Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose is to search for enterocyte-specific or non-specific molecular signature of post-operating recurrence of Crohn's disease in transcriptome (measurement of gene expression through number of mRNA copies transcribed for each gene) and in methylome.

Secondary objectives are to compare expression and methylation profiles according to:

* treatment response
* morphological (endoscopic and/or radiological) and clinical post-operating recurrence.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This aim of this study is to search for new biomarkers predictive of post-operating recurrence.

At present, there are no biomarkers predictive for post-operating recurrence and administration of a post-operating medical treatment to prevent recurrence is based on biological, endoscopic and imagery data.

Predictive biomarkers could allow the identification of patients with high risk of post-operating recurrence and administration of a systematic prophylactic post-operating treatment and at the same time avoiding the prescription of this treatment to patients with low risk of post-operating recurrence.
