Direct clipping using underwater inversion method for colonic diverticular bleeding
Colonic diverticular bleeding is the most common cause of acute lower GI bleeding, sometimes requiring hemostatic interventions, such as endoscopic hemostasis, transcatheter arterial embolization, and surgery. Recently, various methods have been developed to achieve endoscopic hemostasis for colonic diverticular bleeding.1 Endoscopic clipping is widely used because of its rare association with tissue damage and is classified as direct or indirect types. Direct clipping is performed on the exposed vessel in the diverticulum, whereas indirect clipping is performed to close the responsible diverticulum in a zipper fashion.Traction-assisted endoscopic submucosal dissection for a previously tattooed colonic laterally spreading tumor
Endoscopic tattooing is widely performed for preoperative marking; however, colorectal endoscopic submucosal dissection (ESD) after tattooing is challenging because of the dark endoscopic visual field and severe fibrosis at the submucosa.1-4 Previous studies have demonstrated the efficacy of the traction method in colorectal ESD.5,6 Moreover, recent reports have described traction-assisted ESD for technically challenging colorectal cases, such as those involving the appendiceal orifice or diverticulum.Multiloop method for traction during colorectal endoscopic submucosal dissection
Colorectal endoscopic submucosal dissection (ESD) is one of the most challenging procedures. Traction methods for colorectal ESD have been devised to simplify the procedure and reduce the risks of adverse events.1-5 However, several problems remain, especially in terms of versatility and convenience. Therefore, we have devised a multiloop (M-loop) method, which is a traction method using silk thread and clips.
