Objective: To investigate the therapeutic effect of microwave, balloon dilatation and high-frequency electric cutting on esophageal stenosis. Methods: Gastroscopy confirmed esophageal stenosis by the nature, location and extent. According to the nature of the narrow, different parts and levels, the use of endoscopic balloon dilatation and microwave and high frequency electrotomy. Results: Of the 95 cases of esophageal stenosis, 35 cases had anastomotic stenosis, 21 cases of stenosis after radiotherapy, 24 cases of cancerous stenosis, 13 cases of stenosis after chemical burns and 2 cases of unexplained stenosis. Among them, 5 cases were treated by microwave, 3 cases were treated by electrotome and microwave, 57 cases were treated by balloon dilatation and 30 cases were treated by microwave and balloon dilatation. Treatment of 1 to 43 times. The effective rate was 72 (75 79%), effective 21 (21 21%), 1 ineffective (105%), and 1 esophageal perforation (105%). Conclusion: According to the nature, location and degree of esophageal stenosis, endoscopic balloon dilatation, microwave and high frequency electrotomy are used separately or in combination. The method is simple, inexpensive, safe and effective and can be applied to various causes of esophageal stenosis
