Purpose
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 endoscopic and endomicroscopic features of mucosal healing in patients with IBD.

Primary Outcome Measures:
- Mucosal healing [ Time Frame: 3 years ]We will determine endoscopic (e.g. ulcera, erythema) and endomicroscopic features of mucosal inflammation (e.g. goblet cell depletion, leackage, microvessel density) in IBD in order to define new criteria of mucosal healing and to define factors of disease remission and relapse.
Secondary Outcome Measures:
- Histologic correlation [ Time Frame: 3 years ]Comparison of clinical and histopathological data with endoscopic and endomicroscopic findings to evaluate mucosal healing as a parameter of remission and relapse in patients with IBD.
- Therapeutic effect [ Time Frame: 3 years ]We will evaluate the effect of different therapeutic strategies (eg. anti-TNF treatment, corticosteroids) on characteristics of mucosal healing (e.g. goblet cell depletion, microvessels, leakage) and remission and relapse rate.
Biospecimen Retention: Samples With DNA
Biopsies were taken from every patient for subsequent histological analysis.
