A novel technique using high energy synchronous double-wave laser in endoscopic submucosal dissection of patients with superficial esophageal neoplasm

摘要

Background Endoscopic submucosal dissection (ESD) has been widely used to treat superficial esophageal neoplasms (SENs). Intraoperative bleeding is one of the main concerns that makes ESD in the esophagus more difficult and time consuming with higher complication rates. We introduced a novel laser endoknife system that enabled better intraoperative hemostasis, and preliminarily investigated its feasibility in ESD for patients with SENs.
