Intralesional steroid injection to prevent stricture after endoscopic submucosal dissection for esophageal cancer: a controlled prospective study

Background and study aims: The frequency of stricture after endoscopic submucosal dissection (ESD) for esophageal squamous cell carcinoma with a mucosal defect involving more than three-quarters of the circumference is 70 % – 90 %. Stricture decreases quality of life and requires multiple endoscopic balloon dilation (EBD) sessions.
