A Comparative Study of Inhibition of Postsurgical Adhesion Formation in the Rat Model by Nonsteroid Antiinflammatory Drugs , Heparin , Hyskon , and TC-7 / 대한산부인과학회잡지

ABSTRACT

The purpose of this study was to evaluate and compare the effect of inhibition of postsurgical adhesion formation in the rat model by meclofenamate, tolmetin, TC-7, Hyskon, and heparin. Laparotomies were performed on grossly healthy, mature nonpregnant female rats, and proximal 1 cm of each uterine horn was traumatized with unipolar electrocautery. Each rat was randomly assigned to one of six different groups(control, meclofenamate, tolmetin, heparin, TC-7, and Hyskon group), and different solutions or an adhesion barrier were placed into traumatized uterine horn before closure. One week later adhesion formation was scored according to percent involvement of each traumatized uterine horn(0 to 4), and adhesion density(0 to 2), and compared using one-way analysis of variance and Fishers exact test. Compared with the control group, postsurgical adhesion formation was significantly decreased in the TC-7 group(average adhesion score, 1.72), the meclofenamate group(2.19), the Hyskon group(2.53), and the tolmetin group(2.93). The TC-7 group was also significantly decreased in adhesion formation compared with the Hyskon, tolmetin, heparin groups, and meclofenamate group was significantly decreased in adhesion formation compared with tolmetin and heparin groups. There were no significant differences between groups in adhesion density. So we suggest that meclofenamate is a cost-effective agent in inhibition of postsurgical adhesion formation.
