Can image-enhanced endoscopy improve adenoma detection rate?

Area of Science:

• Gastroenterology
• Endoscopy
• Cancer Prevention

Background:

• Colonoscopy with adenoma detection and resection significantly reduces colorectal cancer (CRC) incidence and mortality.
• Adenoma Detection Rate (ADR) is a critical colonoscopy quality indicator strongly linked to subsequent CRC risk.
• Image-Enhanced Endoscopy (IEE) aids in differentiating neoplastic lesions and enhancing adenoma visualization.

Purpose of the Study:

• To review and compare current Image-Enhanced Endoscopy (IEE) modalities for adenoma detection during colonoscopy.
• To evaluate the efficacy of IEE in improving adenoma detection rates (ADR) based on existing evidence.

Main Methods:

• Systematic review of randomized controlled trials (RCTs) and meta-analyses on IEE for adenoma detection.
• Comparison of digital and dye-based IEE techniques.
• Analysis of studies assessing the impact of IEE on adenoma detection rates (ADR).

Main Results:

• Image-Enhanced Endoscopy (IEE) demonstrates potential to improve adenoma detection compared to standard colonoscopy.
• Various IEE modalities show varying degrees of efficacy in enhancing visualization of colonic adenomas.
• Despite proven benefits in studies, IEE is not yet standard practice for colonoscopy.

Conclusions:

• Image-Enhanced Endoscopy (IEE) is a valuable tool for improving adenoma detection during colonoscopy.
• Further integration of IEE into routine practice could enhance CRC prevention by increasing ADR.
• Understanding and comparing IEE modalities is crucial for optimizing colonoscopy quality and patient outcomes.
