EC‑3490TLi Video Colonoscope – RetroView™

The PENTAX EC-3490TLi Video Colonoscope (“RetroView™”) is designed for the endoscopist who is passionate about reducing colonoscopy miss rates and complete removal of polyps. RetroView is designed for diagnostic and therapeutic lower gastrointestinal applications and may provide a more thorough colon study and treatment of polyps. Unlike standard colonoscopes, RetroView features a 210° short turn radius bending section for retroflex scope positioning that provides visualization and accessibility of the proximal side of colon folds and flexures.

Find more polyps
Physician experience using RetroView has indicated a potential to detect more polyps when incorporating retroflex visualization into their colonoscopy withdrawal.1

Remove more polyps
With a 25% smaller retroflex radius and 210 degree retroflex angulation, RetroView™ may provide better scope positioning for access and resection of challenging polyps.

Increase efficiency
RetroView is a slim colonoscope with a short turn radius bending section that may lead to fewer incomplete colonoscopies by easily navigating around the sharp turns and tight areas of a difficult colon.
