title: Endoscopic resection (endoscopic mucosal resection/ endoscopic submucosal dissection) for superficial esophageal squamous cell carcinoma: current status of various techniques.
abstract: Endoscopic resection (ER) has been widely accepted as an effective and minimally invasive treatment for patients with superficial esophageal squamous cell carcinoma (SCC). Techniques of conventional endoscopic mucosal resection (EMR) were first developed for ER. There are three representative methods of conventional EMR: endoscopic esophageal mucosal resection (EEMR)-tube method, EMR using a cap-fitted endoscope (EMRC) method and two-channel EMR method. In the past decade, techniques of endoscopic submucosal dissection (ESD) have become established as standard methods of ER. ESD allows en bloc resection of a lesion, irrespective of the size and shape of the lesion. Recently, results of retrospective cohort studies confirming that ESD is superior to EMR as a curative treatment for superficial esophageal SCC have been reported. Representative knives that are now frequently used in esophageal ESD include Hook knife, Triangle tip knife, IT knife nano, Flush knife-BT, Dual knife, SB knife, and so on. Although there are various knives developed for ESD, the basic techniques for safe and effective ESD are the same.
