Evaluation of Stricturing Crohn's Disease Using Digital Holographic

Status Recruiting

Clinical Trial Summary

Crohn's Disease (CD) patients, belonging to Inflammatory Bowel Disease (IBD), frequently suffer from uncontrolled intestinal inflammation. This can lead to severe disease complications requiring hospitalization. Up to 50% of all CD patients develope intestinal strictures. Intestinal strictures can be subdivided into predominantly inflammatory and predominantly fibrotic types. This subclassification in different types of strictures is important for clinical decision making: patients with predominantly fibrotic strictures would undergo surgery or interventional endoscopic treatment and patients with predominantly inflammatory strictures would be treated anti-inflammatory. To determining the degree of fibrosis and inflammation in CD strictures remains difficult.

Digital holographic microscopy (DHM) is a new imaging approach belonging to the group of quantitative phase imaging. DHM enables stain-free quantitative phase contrast imaging and provides the determination of an refractive index which directly correlated to tissue density.

This study aims to evaluate DHM for assessing the degree of fibrosis and inflammation in surgical specimen from patients with stricturing CD. The investigators collect full thickness surgical resection specimen from 29 patients with symptomatic CD strictures. More detailed, the investigators collect full thickness surgical resection specimen out of stenotic and non-stenotic bowel segments from each patient. For primary purposes, the investigators analyze the obtained tissue using DHM and compare differences of the refractive index, determined by DHM, between stenotic and non-stenotic parts of the intestinal wall. For secondary purposes, the investigators will correlate the findings made by DHM with a detailed analysis by a histopathologist using a scoring system (Goldstandard) to determine the degree of fibrosis and inflammation in the samples.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
