Complex esophageal strictures usually requires numerous endoscopic therapies. There is no consensus endpoint for endoscopic therapy, and which is optimal therapy[4 ]. some person suggested that endoscopic dilatation is the first choice for certain peptic strictures. But for complex strictures, dilatation can not offer durable remission, so the requirement for multiple dilatation treatment sessions. Stenting or endoscopic incision may be performed in patients with complex stenosis who achieve a unfavorable outcome with repeated dilatation21. xx reported that stents could achieved a satisfactory improvement/resolution of the refractory strictures with a success rate of 35%–45%; however, migration rates(25%–35%) and adverse events (20%–25%) are fairly common[16]. A study by Manabu Muto[17] et al. showed that radial incision and cutting is an effective and safe method for gastroesophageal anastomotic strictures that are refractory to repeated endoscopic dilation, at the same time radial incision and cutting also avoided perforation and bleeding, which is consistent with our conclusion. For CES, the use of steroids remains controversial. Using steroids is believed to inhibit the inflammatory response and consequently reduce the stricture formation. Studies have shown that the use of steroid injections, in conjunction with antisecretory therapy and dilations, reduces the number of repeat dilations and increases the dilation-free period[18-19]. But the effectiveness of using steroids was not satisfactory in the case. Therefore, we believe that the preferred choice of steroids for CES is not recommended.
