Combination of immersion in saline solution, pocket-creation method, water-jet hydrodissection, and hybrid knife “probe mode” simplifies endoscopic submucosal dissection in giant rectal polyp

GI endoscopic submucosal dissection using a calibrated, small-caliber-tip, transparent hood for lesions with fibrosis

“…[3][4][5][6] In recent years, the performance of ESD in saline environments has been reported. 7,8 A calibrated, small-caliber-tip, transparent hood (CAST hood; TOP, Tokyo, Japan) has been designed for small intestinal strictures by using a tapered hood that can measure the diameter and perform balloon dilation of the stricture. 9 The CAST hood is a transparent hood with a 4-mm tip diameter that can be used in ESD (Video 1, available online at www.giejournal.…”

Hemostatic forceps used as a scissor-type knife in combination with the transanal-traction method for assisted endoscopic submucosal dissection in the area of the dentate line

“…We used the saline solution immersion technique to facilitate a clear endoscopic view and improve vessel identification. We dissected the submucosa by using a hybrid knife in probe mode 7 while using the forced coagulation mode. This was followed by dissection of the submucosa under the lesion to the area of the dentate line.…”

Novel approach to endoscopic submucosal dissection of a cecal lesion with nonlifting sign by submucosal fatty tissue with use of selective-regulation high-pressure water-jet method and immersion in saline solution

“…5 The water-jet hydrodissection technique has been shown to be effective in underwater ESD in saline solution. 6 Video 1 (available online at www.VideoGIE.org) shows the case of an ESD of a cecal lesion with nonlifting sign.…”

“…6), and it reduced the risk of water intoxication. We cut the submucosa using the T-type hybrid knife probe mode, 6 including vertically (Fig. 7).…”
