Tight near-total corrosive strictures of the proximal esophagus with concomitant involvement of the hypopharynx: Flexible endoscopic management using a novel technique

AIM: To investigate the role of a novel minimally invasive endoscopic technique in the management of tight near-total corrosive strictures of the proximal esophagus involving the hypopharynx. METHODS: Two patients with near-total corrosive strictures of the proximal esophagus involving the hypopharynx were managed with the novel endoscopic technique. The technique involved passing a 0.025-inch flexible guide-wire across the stricture, and stricture dilatation, using 10F coaxial diathermy and balloon dilators, followed by electro-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.
