Effect of vitamin D on postoperative adhesion formation in a rat uterine horn adhesion model.

ABSTRACT

OBJECTIVE: To determine the role of vitamin D for preventing or reducing postoperative adhesions. STUDY DESIGN: The uterine horn adhesion model was carried out in 24 female Wistar rats. The animals were randomized into 4 groups (1) control, (2) Ringer's lactate, (3) olive oil, and (4) vitamin D. Adhesion grade and histologic findings of adhesion-carrying tissues were evaluated, and groups were compared according to these parameters. RESULTS: Rats treated with vitamin D had less adhesion and lower inflammation grade when compared to the control and Ringer's lactate groups, and the results were statistically significant (p < 0.05). On the other hand, no difference was detected between the groups according to the fibrosis score. CONCLUSION: Vitamin D decreased postsurgical adhesion scores by both visual scores and histologic analyses in a rat model. Further experimental and clinical trials are required to confirm these results.
