Water pressure method for duodenal endoscopic submucosal dissection (with video)

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

“…Because it is especially important to create a submucosal flap first in duodenal ESD, the water pressure method, double clips, and rubber band traction have been devised to enable creation of a submucosal flap. 11,12 In this case, by using the tip of the CAST hood, it became possible to easily create a submucosal flap by making a mucosal incision only once. Normally, once the flap is created, the knife is parallel to the muscular layer because the tip of the hood is in close contact with the muscular and submucosal layers on the tumor side.…”

Successful endoscopic submucosal dissection using the water pressure method for cervical esophageal cancer

“…The water pressure method (WPM) is a kind of ESD technique in which waterjet function is utilized to open the submucosal space 1 . It was reported to reduce intraoperative complications of duodenal ESD 2 . Herein, we reported a case of cervical esophageal cancer successfully treated by WPM (Video S1).…”

Making endoscopic submucosal dissection in the duodenum safer: Is it possible?

“…So, is it possible to make duodenal ESD safer with WP as the vehicle? Kato et al 13 give us hope, but only time will tell.…”

“…In a study by Kato et al, 13 the water pressure (WP) method was used to perform ESD of duodenal lesions. Although this was well documented by Binmoeller et al 14 in 2012 for duodenal EMRs, it was hypothesized that this technique could help reduce the perforation risk for ESD as well.…”
