The patients were randomly divided into three groups (random sorting through a computerized list of patients), each of them employing a different means of hemostasis: in Group-I, classic surgical procedures were used to achieve hemostasis (ligatures and bipolar electrocauterization alone); in Group-II, oxidized regenerated cellulose patch (SurgicelA(r) cellulose-based hemostat 2.5x5 cm) was applied, whereas in Group-III, the fibrin-based hemostat (BeriplastA(r) P Combi-Set 1ml) was used.
