Esophageal stricture is one of the complications after esophageal varices sclerotherapy injection (ESI), and the incidence rate is between 2%-10%.
To explore the efficacy of self-expanding metal stent (SEMS) for the stricture after endoscopic injection with cyanoacrylate (CYA) and sclerotherapy for esophageal varices.
We retrospectively analyzed the efficacy of SEMS to improve the stricture after endoscopic injection with CYA and sclerotherapy for esophageal varices in 4 patients from February 2023 to June 2023.
The strictures were improved in four patients after stenting. The stent was removed after two weeks because of chest pain with embedding into esophageal mucosa in one patient. The stent was removed after one month, however, the stent was reinserted because of the strictures happening again in two patients. The stent was removed after three months, however, the stent was reinserted because of the strictures happening again in one patient. The stent embedded into esophageal mucosa in three patients. There were 3 patients suffered reflux esophagitis, and the acid reflux was relieved by taking hydrotalcite. There was no other complication of esophageal perforation, bleeding from varices or infection.
SEMS may relieve the stricture which happened after endoscopic injection with CYA and sclerotherapy for esophageal varices. However, when we should remove the stent still needs to be explored.
食管狭窄是食管静脉曲张硬化剂注射（ESI）后的并发症之一，发病率在2%-10%之间。
探讨自膨式金属支架（SEMS）对内镜下注射氰基丙烯酸酯（CYA）及硬化剂治疗食管静脉曲张后所致狭窄的疗效。
回顾性分析2023年2月至2023年6月期间4例接受SEMS治疗内镜下注射CYA及硬化剂治疗食管静脉曲张后狭窄的疗效。
4例患者置入支架后狭窄均有改善。1例患者因胸痛且支架嵌入食管黏膜于2周后取出支架。2例患者于1个月后取出支架，但因再次发生狭窄而重新置入支架。1例患者于3个月后取出支架，但因再次发生狭窄而重新置入支架。3例患者出现支架嵌入食管黏膜。3例患者发生反流性食管炎，服用铝碳酸镁后酸反流得到缓解。未出现食管穿孔、曲张静脉出血或感染等其他并发症。
SEMS可能缓解内镜下注射CYA及硬化剂治疗食管静脉曲张后发生的狭窄。然而，何时取出支架仍有待探索。
