Summary
Brief summary (as posted)
Endoscopic submucosal dissection (ESD) is a technically difficult and time-consuming procedure. Several water-jet knives have been developed to address this issue. The aim of this study was to develop a new ESD method using continuous low-pressure water injection at 1-2 atmosphere with a tip-injected electric knife while dissection simultaneous cutting, dissection, electrocoagulation, and hemostasis, which was so called as submucosal pressure ejection endoscopic dissection (SPEED) to treat early gastric cancer and compare the efficacy and safety with conventional methods.

- Submucosal pressure ejection endoscopic dissection (SPEED)
- description
- A new ESD method using continuous low-pressure water injection at 1-2 atmosphere with a tip-injected electric knife while dissection simultaneous cutting, dissection, electrocoagulation, and hemostasis, which was so called as submucosal pressure ejection endoscopic dissection (SPEED).
- label
- Conventional ESD (C-ESD)
- description
- A traditional ESD model. Submucosal injection is performed separately from circumferential cutting, dissection, electrocoagulation, and hemostasis. During the submucosal dissection procedures, submucosal injection is performed with the tip of the knife first, followed by the above operations, rather than simultaneously.
