INTEGRATED OPTICAL TOOLS FOR MINIMALLY INVASIVE DIAGNOSIS AND TREATMENT AT GASTROINTESTINAL ENDOSCOPY.

Area of Science:

• Gastroenterology and Endoscopic Technology
• Optical Diagnostics
• Cancer Prevention

Background:

• Gastrointestinal (GI) endoscopy has shifted from treating symptomatic disease to cancer prevention in asymptomatic individuals.
• This shift is driven by decreased peptic ulcer disease and improved endoscopic detection of dysplasia, a precancerous biomarker.
• There is a growing need for minimally invasive, in situ optical diagnostic technologies to assess mucosal changes.

Purpose of the Study:

• To present the development and testing of novel, integrated tissue-sampling tools for GI endoscopy.
• To incorporate fiberoptic probes for spectroscopy or endomicroscopy into familiar endoscopic instruments.
• To demonstrate the preliminary performance and value of these integrated tools in clinical studies.

Main Methods:

• Development of standard tissue-sampling tools enhanced with fiberoptic probes.
• Integration of spectroscopy and endomicroscopy capabilities into these tools.
• Testing and performance assessment through ongoing clinical studies.

Main Results:

• The developed integrated optical tools show promise for screening and surveillance applications in GI endoscopy.
• Preliminary performance data from clinical studies support their utility.
• These tools can aid in dysplasia surveillance, potentially reducing the number of benign biopsies.

Conclusions:

• A new generation of integrated optical tools is emerging for GI endoscopy.
• These tools offer enhanced capabilities for dysplasia surveillance, including for conditions like Barrett's esophagus and inflammatory bowel disease.
• Integrated devices are expected to be invaluable for optimizing screening and surveillance strategies, improving clinical outcomes.
