Rosuvastatin administered intraperitoneally reduces the formation of postoperative adhesions in rats.

OBJECTIVES

The purpose of the present experimental research was to assess the efficacy of intraperitoneal administration of rosuvastatin in preventing the formation of postoperative peritoneal adhesions.

MATERIAL AND METHOD: Peritoneal adhesions were induced in 120 male rats of the Wistar-Bratislava breed, divided into 4 groups (n=30), using a parietal and visceral abrasion model. Group I was designated as the control group; in the case of group II, a saline solution was administered intraperitoneally, while in the case of groups III and IV, rosuvastatin solution with a concentration of 10 mg/kg and 5 mg/kg, respectively, was administered in a single dose, during laparotomy. All rats were sacrificed on the 14th postoperative day and the peritoneal adhesions were assessed macroscopically and microscopically.

RESULTS

The formation of peritoneal adhesions (assessed macroscopically by appreciating their number, the area covered, and the degree of severity) was statistically significantly more reduced in the subjects that received rosuvastatin (groups III and IV) as compared to the control group (p<0.05). The degree of fibrosis assessed microscopically was also statistically significantly reduced in groups III and IV as compared to the control group (p<0.05).

CONCLUSIONS

Rosuvastatin administered intraperitoneally correlates with a reduction of peritoneal adhesions in rats.
