Abstract    Endoscopic submucosal dissection is the newly developed technique for treating superficial cancer in esophagogastric junction (EGJ) as well as early gastric cancer. For the treatment of adenocarcinoma of the esophagogastric junction（AEG）and precancerosis in EGJ, endoscopic submucosal dissection (ESD) has obvious advantages compared with laparotomy and endoscopic mucosal resection (EMR). But for the lesions in EGJ, ESD is difficult with long operation time and high complication incidence, which should be performed only by the skilled surgeons.
