Peritoneal adhesions are pathological fibrotic bands formed between organs and tissues of the abdominal cavity that are normally separated.They present in 93% of patients after abdominal or pelvic surgery and, they are cause of abdominal pain and intestinal obstruction. Some authors have suggested that the use of steroids may decrease the number and severity of adhesions.The goal was to experimentally evaluate the effects of methylprednisolone, in postoperative peritoneal adhesions in an animal model. So an experimentally study was done, a laboratory assay in an animal model. In 10 female Sprague-Dawley rats, peritoneal adhesions were induced, and then randomly assigned to 2 groups: a group treated with methylprednisolone, and a control group.The animal were killed and evaluated at the 15th day after surgery. A significant decrease in inflammation (p=0.027) in the group with administration of methylprednisolone was evident. However, there were no significant differences between the groups in relation to the number (p=0.482), severity (p=0.489), vascular proliferation (p = 0.207) and fibrosis score (p=0.095) of peritoneal adhesions.This study demonstrated that the administration of methylprednisolone doesn't affect the postoperative peritoneal adhesions formation, and therefore, is not have a preventive effect of them.
