Endoscopic submucosal dissection as the fastest growing endoscopic treatment technology in the past decade has been widely used in the treatment of early esophageal cancer and gastric cancer without local lymph node metastasis. The main complications of ESD treatment of early esophageal cancer are hemorrhage, perforation, postoperative esophageal stenosis, infection, etc. Postoperative esophageal stenosis is the most common and major complication after ESD treating patients with lesion involving more than 2/3 esophagus cycle. It is very important to prevent esophageal stricture after ESD. Glucocorticoid is gradually concerned by clinical research because it can inhibit local inflammatory response and reduce the formation of connective tissue in order to prevent postoperative stenosis. The specific usages include endoscopic injection of corticosteroids, oral corticosteroids and combination of them. The study shows that the incidence of esophageal stricture after using glucocorticoid can be reduced effectively. Currently, there is no uniform consensus on the use of glucocorticoids, such as specific drugs, dosage, course of treatment, route of administration. In particular, efficacy comparison of different routes of administration is laking. Studies have shown that endoscopic injection triamcinolone acetonide in some patients with intractable esophageal stricture is not very effective, but it can be treated with oral corticosteroids. Aluminium Phosphate Gel is a kind of neutral buffer. The main component aluminum phosphate can form a strong ion buffer system in acidic environment. The structure of its auxiliary components agar and pectin is similar to that of natural mucus. It forms a mucous layer in the esophagus to restore and protect the esophageal mucosa. Therefore, investigators assume the hydrocortisone sodium succinate aluminum phosphate mixed gel can be used for preventing postoperative ESD stenosis of patients with a large area of early esophageal cancer. This study will design a randomized controlled trial to compare the effect of oral hydrocortisone sodium succinate mixed Aluminium Phosphate Gel and local injection of triamcinolone acetonide plus oral prednisone for the prevention of ESD postoperative esophageal stricture in patients with a large area of early esophageal cancer.
