Area of Science:

Gastroenterology
Medical Devices
Endoscopic Imaging

Background:

Colonoscopy is the gold standard for colorectal cancer screening but has limitations.
Missed polyps occur in challenging locations like folds and valves.
Computed tomography colonography and barium enema confirm these blind spots.

Purpose of the Study:

To review the Third Eye Retroscope, a novel device for colonoscopy.
To assess its potential to improve mucosal visualization.
To discuss its clinical efficacy and challenges.

Main Methods:

Review of existing literature and device information.
Analysis of the rationale behind enhanced mucosal exposure.
Discussion of clinical implementation and potential benefits.
