[Research progress in endoscopic incision in treating gastrointestinal benign stricture].

Gastrointestinal benign stricture is a common disease with symptoms of dysphagia, abdominal pain and difficult defecation, which severely impair the quality of life for patients. Endoscopic intervention is the first-line treatment, and the available methods include balloon dilation, local drug injection and stent insertion, etc. Endoscopic incision was first used for the treatment of Schatzki's rings, and later it was used for the treatment of other gastrointestinal benign strictures, and the promising results were achieved.
