Bringing Innovation to Gastric Cancer Screening—Unchanged for 50 Years
Creating New Value Through Clinical Experience and Medical Device Innovation
The World’s First Screening-Specific Solution

Endoluminal Solutions Inc. is creating new value in Japan’s healthcare system through the development of an innovative endoscopic system dedicated to gastric cancer screening.
Our screening-specific disposable endoscope (gastroscope) features three key innovations: the world’s thinnest diameter, a fully single-use design, and ultra-low cost. While conventional endoscopes have evolved into highly sophisticated devices for diagnosis and treatment, we take a fundamentally different approach. Through “zero-based development,” we build from the ground up—focusing only on the functions truly required for screening—to create a device optimized for this purpose.
Barium-based screening, which has been the standard since the 1970s, has reached a turning point. With limitations in detection accuracy and concerns over radiation exposure, its historical role is coming to an end. Participation in barium screening continues to decline, while the transition toward endoscopic screening as a new standard is now being seriously discussed.
We do not simply point out these challenges. By providing a practical and easily adoptable new screening solution, we are committed to addressing this critical societal issue.
