Topical Mitomycin C application for esophageal stricture: Safe, precise, and novel endoscopic technique

PurposeThe first line of management of benign esophageal stricture is endoscopic dilatation; however, multiple sessions are usually indicated especially in resistant cases. Topical Mitomycin C (MCC) application is a new adjuvant treatment in the management of esophageal stricture with promising results in different case series. Several techniques have been reported for application; nevertheless, the ideal technique has not been described yet.Material and MethodsIn this series we have devised a new technique using both the flexible and the rigid endoscope and a specially designed Nelaton catheter.ResultsThis technique was applied in 38 sessions for 16 caustic esophageal strictures with technical success in all cases. No procedure-related complications were observed in this series.ConclusionThis novel technique is feasible and effective and can be considered as standard for topical MMC application on esophageal stricture.
