Local triamcinolone injection and selective add-on oral steroids to prevent esophageal post-endoscopic submucosal dissection stricture: a retrospective analysis in a Western center

Extensive esophageal endoscopic submucosal dissections (ESDs) without preventive measures carry a high risk of stricture. Oral steroids and local injection of triamcinolone acetonide have proven to be effective in Asia for the prevention of esophageal stricture. This study aimed to assess the efficacy of a systematic steroid administration protocol for stricture prevention in a Western center.
