LOCAL INJECTION OF TRIAMCINOLONE ACETONIDE WITH SELECTED ADDED ORAL STEROID THERAPY AFTER EXTENSIVE ESOPHAGEAL ESD TO PREVENT STRICTURE: A PROSPECTIVE VALIDATION PROTOCOL IN WESTERN COUNTRIES

Aims Oral steroid is usually administered in Western countries to prevent post-ESD esophageal stricture after extensive resection. A single local injection of triamcinolone acetonide (TA) at the end of ESD has been demonstrated to be effective for resections comprising 50 to 90% of circumference in Japan.
