The technique involved passing a 0.025-inch flexible guidewire across the stricture, and stricture dilatation, using 10 F coaxial diathermy and balloon dilators, followed byelectro-incision of the proximal aspect of the residual eccentric stricture by means of a novel approach using a wire-guided sphincterotome.RESULTS Both patients were successfully managed on an outpatient department basis with the complete relief of symptoms and resolution of strictures on endoscopy and an esophagogram. No adverse events were seen during or after the procedure. There was no recurrence of symptoms at a follow-up of over a year in both cases. There was a significant improvement in the body mass index of both patients after the procedure.CONCLUSION We report a novel flexible endoscopic technique for the management of complex hypopharyngo-esophageal strictures. In experienced hands, the procedure is relatively simple, safe and effective with a durable response.展开更多
