    Abstract:
    BACKGROUND: Frequent sessions of endoscopic dilatation are usually required in the management of benign esophageal strictures, especially caustic induced ones. Topical mitomycin C (MMC) has been recently used in the management of resistant strictures. This study evaluated the efficacy of MMC application in prevention of stricture recurrence after endoscopic dilatation. PATIENTS AND METHODS: This double-blind, randomized, placebo-controlled trial included forty patients with caustic esophageal strictures dating from January 2008 to October 2010. Patients were randomized into 2 groups to undergo endoscopic dilatation with application of either MMC versus placebo on stricture site. Regular follow up and re-evaluation were done after 6 months of management. The number of dilatation sessions needed for resolution of dysphagia in each group was our primary outcome. RESULTS: During the specified follow up period, 80 % of strictures in the MMC group got completely resolved compared to only 35% in the placebo group. The mean number of dilatation sessions needed in the MMC group was n = 3.85 ± 2.08 compared to n = 6.9 ± 2.12 in the placebo group which was statistically significant (p < 0.001). CONCLUSION: Mitomycin C application significantly reduced the number of dilatation sessions needed to alleviate dysphagia in patients with caustic esophageal strictures.
