Double Endoscopic Intraluminal Operation (DEILO) for Early Gastric Cancer: Outcome of Novel Procedure for Endoscopic Submucosal Dissection.

Endoscopic submucosal dissection (ESD) has been used to treat patients with early gastric cancer (EGC). Although several endoscopic devices have been developed to ensure easy and safe ESD, this technique still requires an experienced, highly skilled endoscopist, as it is performed through a single gastroscope, thus requiring one-handed surgical techniques. To overcome these limitations, many ESD procedures with counter-traction have been developed, such as the double scope, double channel scope, clip with line, magnetic anchor, percutaneous traction and external grasping forceps methods. We devised a double endoscopic intraluminal operation (DEILO). Two endoscopes were simultaneously inserted into the stomach. One endoscope was used to lift the lesion, and the other was used to excise the lesion. The DEILO procedure was performed on 122 cases of EGC. In this article, we report the efficacy and safety of DEILO in patients with EGC. Copyright
