Amber-red color imaging makes the dissection line more evident during gastric endoscopic submucosal dissection.

ABSTRACT:

Background and study aims

Local injection of a small amount of blue dye into the submucosa can facilitate recognizing the dissection line in endoscopic submucosal dissection (ESD). Amber-red color imaging (ACI), which hardly affects the submucosal blue color, is suitable for the entire ESD. This study aimed to clarify characteristics of ACI during ESD.

Patients and methods

Nine endoscopic images were selected during submucosal dissection in four cases of gastric ESD to evaluate endoscopic ACI and white light imaging (WLI). Visibility of the dissection line and the submucosal vessel were evaluated by eight endoscopists using a 5-point Likert scale. The blue submucosal area of each endoscopic image and color signal surrounding the submucosa were compared between ACI and WLI. I
