Effect of intraperitoneal curcumin instillation on postoperative peritoneal adhesions

Abstract

Objective: The aim of this study was to determine the effect of curcumin on adhesion formation in a rat cecum abrasion model. Materials and Methods: Thirty Wistar rats were randomized into three groups; the control group received saline, the curcumin group received 10 mg/kg of curcumin after cecal abrasion, and in the sham group the abdominal wall was closed without any abrasion to the cecum. On day 15, adhesions were assessed blindly using a standardized scale, and histopathological samples were taken and examined. Results: There were no incisional hernias or wound dehiscences in any animals of the three groups. A comparison of adhesion scores showed a significant difference between the curcumin (median = 1) and the control group (median = 2; p < 0.05). The grade of inflammation of the curcumin (median = 1) and the sham (median = 0) group was significantly lower than that of the control group (median = 3; p < 0.01 and p < 0.001, respectively). Hydroxyproline levels were significantly lower in the sham (48.3 ± 11.8 μg/mg) and the curcumin (63.8 ± 13.9 μg/mg) group compared to the control group (85.7 ± 22.1 μg/mg; p < 0.05). Conclusion: These data suggest that curcumin, administered intraperitoneally, was effective in the prevention of peritoneal adhesion formation.
