Abstract: | BACKGROUND: To assess the effects of halofuginone, a specific inhibitor of synthesis of collagen type 1, which is the major constituent of fibrosis, on esophageal stricture formation due to caustic ingestion. METHODS: Sixty rats were divided into four equal groups: control group; sham laparotomy group; caustic injury without treatment group; caustic injury with halofuginone treatment group. Caustic injuries were done by 50% sodium hydroxide. Halofuginone was administered by the first postoperative day. All animals were sacrificed on day 21; and the results were evaluated by hydroxyproline levels, stenosis index, lumen diameter, histopathological evaluation, wall thickness, and animal weights. RESULTS: Mortality differences were significant comparing group 3 with group 1 and 2 (P = 0.006) and group 4 (P = 0.03). According to hydroxyproline levels, the differences are significantly higher (P <0.001) comparing group 3 with group 1, 2, and 4. The P value was considered significant in all other parameters (P <0.001) for all the groups but group 1 versus group 2 (P >0.05). CONCLUSIONS: Halofuginone, a specific inhibitor of collagen type 1 synthesis, significantly reduced esophageal stricture occurrence. |
