[Use of corticosteroids after esophageal dilations on patients with corrosive stenosis: prospective, randomized and double-blind study].

OBJECTIVE: To determine triancinolone intralesional injections effects in association with esophageal dilations in corrosive stenosis cases, by means of a double-blind and randomized study.

METHOD: Fourteen adults patients (6 men and 8 women) with severe esophageal corrosive stenosis were randomized in two groups: Group A: treated by esophageal dilations and posterior triancinolone 10 mg/ml intralesional injection; Group B: treated by esophageal injections and posterior saline solution 0,9% injection (placebo). New applications were made based on the patient symptomatology. It had been analysed dilation frequency, obtained diameters and dysphagia before and after the research, for 12 months.

RESULTS: Eleven patients had ingested sodium hydroxide, two had ingested ammoniac and one had taken muriatic acid. There was no statistic difference (p > 0.05) in dilation frequency and dysphagia between the groups. However, an improvement in obtained diameter was observed in the corticosteroids group in comparison with control group (p < 0.05). By comparing groups before and after steroids, the final results were very favorable in group A CONCLUSION: Multiple intralesional injections of triancinolone hexacetonide 10 mg/ml in association with esophageal dilations increase obtained diameters in succeeding sessions.
