Infrared endoscopic system for bleeding-point detection after flushing with indocyanine green solution (with videos).

Background: Infrared endoscopy is used to visualize vessels in the GI tract. By applying this system, we developed a new method to visualize a bleeding point during endoscopic resection.

Objective: This study aimed to evaluate the ability of infrared endoscopy to detect a bleeding point during endoscopic resection and to elucidate the mechanism required for clear visualization of a bleeding point by in vitro color analysis.
