    Abstract:
    INTRODUCTION: The cornerstone treatment for benign esophageal strictures is endoscopic dilation. There are reports suggesting that intralesional corticosteroid injection decreases the frequency of endoscopic dilation. METHODS: Seventy-one patients (mean age 42.39 [17.52] years; range, 13-78 years) with benign esophageal strictures (corrosive 29, peptic 14, anastomotic 19, radiation-induced 9) were recruited for this study. All were being managed with a program of intermittent endoscopic dilation by using over-the-wire polyvinyl dilators. All patients were treated by intralesional injections of triamcinolone acetonide (40 mg/mL diluted 1:1 with saline solution) by using a 23-gauge, 5-mm long sclerotherapy needle in aliquots of 0.5 mL. At each session, 4 injections (4 quadrants) were made at the proximal margin of the stricture with another 4 injections into the strictured segment itself whenever possible. The intervals between dilations and frequency of dilations were calculated before and after triamcinolone injections. A periodic dilation index (defined as number of dilations required per month) before and after the triamcinolone injections was calculated. RESULTS: The overall mean (SD) duration of treatment before intralesional injection was 10.9 (19.8) months (range, 1-120 months) and the mean number (SD) of esophageal dilations required was 9.67 (13.06) (range, 1-70). The mean number of sessions of intralesional injection was 1.4 (0.62). After initiation of intralesional injections mean follow-up was 8.1 (5.6) months (range 3-30 months) and the mean number of esophageal dilations was 3.8 (3.0) (range 0-16). The periodic dilation index decreased significantly from 1.24 (0.05) (range 0.13-3.16) before injection to 0.5 (0.33) (range, 0-2) after injection (p < 0.001). For each category of stricture, the periodic dilation index decreased significantly: corrosive, 1.24 (0.5) to 0.53 (0.34) (p < 0.001); peptic, 0.92 (0.44) to 0.42 (0.2) (p < 0.001); anastomotic, 1.24 (0.49) to 0.51 (0.4) (p < 0.001); and radiation-induced, 1.32 (0.6) to 0.6 (0.3) (p < 0.02). CONCLUSION: Intralesional injections of triamcinolone augment the effects of dilation in patients with benign esophageal strictures.
