Endoscopic cicatrectomy for corrosive esophageal strictures just below the piriform fossa

• We performed endoscopic cicatrectomy for corrosive esophageal strictures.
• In this case reported, repeated balloon dilatation therapy failed.
• Endoscopic cicatrectomy and triamcinolone acetonide injection proved most effective.
• However, multiple cicatrectomies were required.
• Endoscopic cicatrectomy could be one useful surgical option.

Corrosive esophageal strictures have been primarily treated using balloon dilatation or endoscopic bougienage. However, many patients experience recurrence after dilatation, and surgical interventions such as esophageal replacement have been attempted. We have performed endoscopic cicatrectomy using a laryngoscope for corrosive esophageal stricture just below the piriform fossa to minimize surgical invasiveness. In this case reported, repeated balloon dilatation therapy failed, and the combination of endoscopic cicatrectomy and intralesional triamcinolone acetonide injections proved most effective even though multiple cicatrectomies were required. If esophageal strictures are close to the piriform fossa, endoscopic cicatrectomy could be one useful surgical option.
