OBJECTIVE: To determine the relative ability of meclofenamate sodium, a water-soluble inhibitor of both prostaglandin and leukotriene synthesis, to inhibit adhesion reformation. DESIGN: Prospective, randomized study in a rabbit model. INTERVENTIONS: Laparotomies were performed on mature New Zealand White rabbits, and each uterine horn was devascularized and traumatized with unipolar electrocautery. One week later, adhesions were microsurgically lysed. Each rabbit was randomly assigned to one of five different groups, and different solutions or an adhesion barrier were placed into the peritoneal cavities before closure: [1] control, 40 mL of normal saline (n = 8); [2] meclofenamate, 1.75 mg/mL in 40 mL of normal saline (n = 7); [3] Hyskon, 40 mL of 32% dextran-70 (n = 6); [4] meclofenamate 1.75 mg/mL in 40 mL of 32% dextran-70 (n = 6); and [5] TC-7, 40 mL of normal saline plus oxidized regenerated cellulose fabric, Interceed, placed over the site of adhesion lysis (n = 6). Two weeks later, adhesion reformation was scored according to percent involvement of each uterine horn (0 to 4), and adhesion density (0 to 1) and compared using a one-factor analysis of variance. RESULTS: Adhesion reformation was greatest in the control group (mean score +/- SEM, 3.7 +/- 0.4) and was decreased, but not significantly, in the Hyskon group (2.7 +/- 0.4). Compared with the control group, reformation was significantly decreased in the meclofenamate group (2.3 +/- 0.2), the TC-7 group (2.0 +/- 0.5), and the meclofenamate/Hyskon group (1.1 +/- 0.3). This last group was also decreased compared with the meclofenamate and Hyskon groups. CONCLUSION: Meclofenamate significantly inhibits adhesion reformation in the rabbit model, especially when used in combination with a 32% dextran-70 solution.
