Topical mitomycin C versus intralesional triamcinolone in the management of esophageal stricture due to caustic ingestion

Esophageal stricture due to caustic ingestion is one of the most difficult problems to manage. Esophageal dilations are the usual treatment and they require a great number of sessions in the majority of cases. This implies time, risks for the patient, anguish for the relatives, and very often, frustration for the physician. To evaluate the efficacy of the application of topical mitomycin C and intralesional triamcinolone in the prevention of post-dilation esophageal stricture recurrence. A prospective, comparative, nonrandomized, and longitudinal study was conducted that compared a cohort of 16 patients treated with mitomycin C (2009-2012) with a retrospective cohort of 34 patients treated with triamcinolone (2002-2009). The patients treated with intralesional triamcinolone had a median of 11 dilations (minimum 4 and maximum 24), whereas the median in the patients treated with topical mitomycin C was 4.5 (minimum 3 and maximum 8). The groups were compared using the Mann-Whitney U test, finding a statistically significant difference of a two-tailed P
