Early canceration of esophageal cancer, how to treat it better?

If endoscopic biopsy shows that cancer cells have not invaded submucosa and there is no local lymph node metastasis, endoscopic surgical resection, namely ESD, can be considered. Indications of ESD in esophageal lesions: (1)Barrett's esophagus (2) Early esophageal cancer: Early esophageal cancer is confined to submucosa and submucosa without lymph node metastasis; (3) Precancerous lesions of esophagus: EMR is used for lesions with a diameter less than 2 cm, and ESD is recommended for lesions with a diameter less than 2 cm. (4) Benign tumors of esophagus: including polyps, leiomyomas and esophageal papillomas. If the above conditions are not met, only esophageal cancer surgery can be done, which is very traumatic. It still needs to be analyzed according to the specific situation.
