  Purpose

Purpose:

The main objective of this study is to determine endomicroscopic features of Crohn´s disease.

Background:

Crohn´s disease is an inflammatory disease of the intestines that may affect any part of the gastrointestinal tract from anus to mouth, causing a wide variety of symptoms. Diagnosis is based on several histologic features including transmural pattern 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.

Scope:

In patients with Crohn´s disease.

Primary Outcome Measures:
  • To determine endomicroscopic features of Crohn´s disease. [ Time Frame: October 2009 until May 2010 ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Comparison of CLE findings with conventional histology. [ Time Frame: October 2009 until May 2010 ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 40

Study Completion Date: August 2011

Detailed Description:

Methods:

Patients underwent colonoscopy for the evaluation of Crohn´s disease. During the endoscopic procedure CLE will be performed.

Procedure:

The patient underwent colonoscopy. During the procedure the patient will receive intravenous fluorescein or topical mucosal staining with acriflavin or cresyl violet, followed by in-vivo CLE of the tissue. Confocal images are digitally saved and analyzed afterwards.
