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

Outcome Measures

Primary Outcomes (1)

  • Mucosal healing

    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.

    3 years

Secondary Outcomes (2)

  • Histologic correlation

    3 years

  • Therapeutic effect

    3 years

Study Arms (4)

Crohn's disease (CD)

Patients with CD and mucosal healing on endoscopy.

Device: Endoscopy (EPK-i, Pentax, Tokyo, Japan)

Crohn's disease

Patients with CD and mucosal healing on endomicroscopy.

Device: Endomicroscopy (iCLE, Pentax, Tokyo, Japan)

Ulcerative colitis (UC)

Patients with UC and mucosal healing on endoscopy.

Device: Endoscopy (EPK-i, Pentax, Tokyo, Japan)

Ulcerative colitis

Patients with UC and mucosal healing on endomicroscopy.

Device: Endomicroscopy (iCLE, Pentax, Tokyo, Japan)

Interventions

Patients will undergo white-light endoscopy. Any mucosal lesions will be recorded and findings will be compared to histopathological and clinical results.

Crohn's disease (CD)

Patients will undergo endomicroscopy. Data will be recorded and findings will be compared to histopathological and clinical results.
