Objective: To determine whether colchicine, an antiinflammatory drug, is effective in reducing adhesion formation in a rabbit model in which pelvic inflammation was produced by injection of a suspension of Neisseria gonorrhoeae into the uterine horn.
Methods: Following inoculation, the rabbits were divided into four groups of 11 animals each. The control group received 1 mL saline intramuscularly (IM) for 14 days. Another group received one 100-mg dose of ceftriaxone IM 2-4 hours after inoculation. The third group received one 100-mg dose of ceftriaxone IM 2-4 hours after inoculation and 1 mg colchicine IM daily for 14 days. The fourth group received 1 mg colchicine IM daily for 14 days. The day after the last injection of colchicine, the rabbits were sacrificed and the abdominal cavities were explored to determine the number and grade of adhesions.
Results: The incidence of adhesions in the control group was similar to that in the antibiotic-treated group, suggesting that antibiotics do not prevent adhesions in this model. Similarly, the incidence of adhesions in the colchicine and antibiotic group was not different from that in the group receiving colchicine alone. However, the colchicine-treated groups had significantly fewer adhesions than the groups not treated with colchicine (P<.0005).
Conclusions: In this model, antibiotics alone did not prevent the formation of adhesions. Colchicine, alone or in combination with antibiotics, was effective in preventing bacteria-induced pelvic adhesions. Therefore, colchicine may offer a novel approach to the prevention of adhesions associated with pelvic inflammatory disease in women.(Obstet Gynecol 1993;81:118-21)
