Clinical Trial Summary

Inflammatory bowel disease (IBD) encompasses two major forms of chronic intestinal disorders, Crohn's disease and ulcerative colitis (UC). Diagnosis is based on several macroscopic and histologic features including patterns of inflammation, crypt abscesses and granulomas. Confocal laser endomicroscopy (CLE) is rapidly emerging as a valuable tool for gastrointestinal endoscopic imaging, enabling the endoscopist to obtain an "optical biopsy" of the gastrointestinal mucosa during the endoscopic procedure. The main objective of this study is to determine endomicroscopic features of mucosal healing in patients with IBD.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Mucosal healing	We will determine endomicroscopic features of mucosal inflammation (e.g. goblet cell depletion, leackage, microvessel density) in IBD in order to establish a new endoscopic classification of mucosal healing.	up to three years
Secondary	Histologic correlation	Comparison of clinical and histopathological data with endoscopic findings to evaluate mucosal healing as a parameter of remission and relapse in patients with IBD.	up to three years
Secondary	Therapeutic effect	We will evaluate the effect of different therapeutic strategies (eg. anti-TNF treatment) on characteristics of mucosal healing (e.g. goblet cell depletion, microvessels, leakage).	up to three years
