Case Video
An approximately 20 mm pedunculated polyp (Paris Ip, JNET 2a) at the distal sigmoid with a slightly eroded and irregular surface due to friction caused by a high peristaltic activity at this level. Underwater colonoscopy causes the polyp to lift up and can be easily captured with the snare. Polypectomy was performed in air phase (Co2). Diathermia resection went rather fast resulting in a pulsating bleeding. RDI™ technology mode 1 made the bleeding easy to detect and coagulate. RDI™ technology reduced the time to manage the bleeding avoiding major complications.
Overall Comment
RDI™ technology mode 1 seems to enhance the visibility of the bleeding source making hemostasis quick and easy.1 It also may help to reduce the stress on the endoscopist.1
