Utility of red dichromatic imaging for identifying the bleeding point in endoscopic hemostasis of colonic diverticular bleeding
An 82-year-old woman was admitted to our hospital because of hematochezia without pain. She had been admitted to our hospital several times in the previous year for colonic diverticular bleeding (CDB) and had already undergone multiple hemostatic treatments for the CDB. A previous plain computed tomography scan had showed multiple colonic diverticula in the ascending colon and sigmoid colon (Fig. 1), so recurrent colonic diverticular hemorrhage was the primary differential diagnosis.Red dichromatic imaging in peroral endoscopic myotomy: a novel image-enhancing technique
A 40-year-old man presented with a 1-year history of difficulty in swallowing liquids and solids. His Eckhart’s score was 6 of 12. EGD showed dilated esophagus with liquid stasis and mild resistance noted across the gastroesophageal junction. Esophageal manometry showed elevated integrated relaxation pressure with panesophageal pressurization (achalasia cardia type II). Peroral endoscopic myotomy (POEM) was planned and was performed using the novel Evis X1 endoscopy (Olympus Corporation, Tokyo, Japan) system.Endoscopic submucosal dissection of early-stage rectal cancer using full-time red dichromatic imaging to minimize and avoid significant bleeding
Management of bleeding during endoscopic resections (and even more so in endoscopic submucosal dissection [ESD]) is a critical aspect of the procedure. The low rectum has a higher risk of bleeding because of a rich venous plexus; this can increase procedure time compared with the proximal rectum.1 Red dichromatic imaging (RDI), a novel image-enhanced endoscopy technology, has been reported to improve the visibility of deep vessels and bleeding points compared with white-light imaging (WLI).2-4 WLI can be switched to RDI instantly with the press of a single button on the endoscope.
