The treatment of long benign oesophageal strictures remains a clinical challenge. We present a novel endoscopic technique that involves visualising scar tissue using methylene blue-stained saline, followed by longitudinal incision down to the muscularis propria to release the stricture and subsequent triamcinolone injection. In a retrospective series of 11 patients over 106 months, this approach was the primary treatment in 8 cases. Short-term clinical success was achieved in all but one patient, who required retreatment during a minimum follow-up of 6 months (mean follow-up: 11.4 ± 7.4 months). Further studies are warranted to define optimal patient selection and assess long-term efficacy.
