BACKGROUND: To assess the effectiveness of different doses of methylprednisolone on preventing intraabdominal adhesions established experimentally in rats. METHODS: Forty female Wistar rats were divided into four groups: high-dose steroid (16 mg/kg), low-dose steroid (10 mg/kg), serum physiologic, and control. Following median laparotomy and procedure for adhesion formation in all rats, 16 mg/kg methylprednisolone (high-dose steroid group), 10 mg/kg methylprednisolone (low-dose steroid group), or serum physiologic (serum physiologic group) was administered into the intraperitoneal space, topically. No additional procedure was applied to rats in Group 4 (Control). All rats were sacrificed on day 15 postoperatively, and intraperitoneal adhesions were assessed according to Linsky's scale. RESULTS: No significant differences were determined between the groups with respect to severity (p=0.867), degree (p=0.919), extent (p=0.876), and general scores (p=0.574) of adhesion formation. Wound infection rates were also similar in the four groups (p>0.05). CONCLUSION: There was no difference in the effectiveness of different methylprednisolone doses, administered topically, in preventing intraabdominal adhesion formation, and furthermore, steroids do not prevent intraabdominal adhesion development.
