RESUMO
BACKGROUND: Adhesion formation is a common complication of abdominal surgeries. Mesna is a drug with fibrinolytic properties which has been used in surgical field to facilitate tissue dissection. The aim of this experimental animal study was to investigate the effect of mesna on prevention of intra-abdominal adhesion in rats. MATERIALS AND METHODS: Twenty-eight Wistar albino rats were used in the study. To create abdominal adhesion, cecum was abraded in all rats. No additional surgical procedure was performed other than adhesion in group 1 (only adhesion). In the other groups, rats were treated topically by administering 0.9% saline (group 2), 40 mg/kg mesna (group 3), and 400 mg/kg mesna (group 4). All rats were sacrificed on postoperative 21st day. Histopathological and macroscopic evaluations of adhesion formation were performed. RESULTS: Quantity of adhesion scores (P = 0.022), severity of adhesion scores (P = 0.041), total adhesion scores (P = 0.023), and histopathological adhesion grading scores (P < 0.001) were reduced by 400 mg/kg mesna. CONCLUSIONS: This is the first study for mesna on prevention of abdominal adhesion formation in rats. We concluded that dose-dependent reduction of adhesion was achieved by mesna. With future studies, topical administration of mesna during open abdominal surgeries may be used to prevent adhesion formation.
