Current endoscopic management for CES includes esophageal dilatation, stent placement, endoscopic incision, injection of steroids into the strictures segment, and so on[4]. The foremost goal of therapy for CES is to preserve the esophagus and restore its function. Dilatation has been considered as the therapy of choice for CES and can be performed endoscopically, using a balloon dilator or rigid dilator. Esophageal stent placement or endoscopic incision is indicated when dilatation is not successful. Several case series reports have shown that endoscopic therapy is a safe and effective therapy with CES[5-7]. However, there is still a lack of a well-established consensus on when and how to optimize endoscopic therapy with CES. Here, we report the case of a male Chinese patient with CES with scar constitution due to the ingestion of caustic soda achieved a favorable outcome after repeated different endoscopic therapy to compare the safe and effectiveness of different endoscopic therapy.
