Comparison of avitene, topical thrombin, and gelfoam as sole hemostatic agent in tuboplasties.
Forty-eight virgin guinea pigs were subjected to bilateral sectioning of the uterine horn and cuff type salpingostomy. Avitene, Topical Thrombin, or Gelfoam was used as the sole hemostatic agent in each of three study groups. Bipolar cauterization was used in a control series. These agents were compared with regard to ease of application, degree of adhesion formation, net surface area, and microscopic evaluation of degree of fibrosis and inflammatory reaction. The results revealed no statistically significant differences among the various methods of hemostasis. Data were evaluated by uni- and multivariate analyses. Several trends in the data were noted: the greatest amount of fibrosis was associated with Topical Thrombin and Avitene, and the greatest inflammatory response was associated with Avitene. These agents show no superiority to currently used cautery methods of obtaining hemostasis.
