Abstract: Background: Abdominoplasties carried out in patients previously underwent gastroplasty present high rates of complications, including increased bleeding in the intra- and postoperative periods. Methods: This study evaluated bleeding, coagulation parameters (coagulogram, dosage of fibrinogen, FII, FV, FVII, FVIII, FIX, FX, and FXII), and thromboelastography in two groups of women who underwent abdominoplasties: a group with a history of gastroplasty by the Fobi-Capella technique (group I) and the other group without a history of obesity (group II). Analyses were performed before, during, and after each surgical procedure. Vitamins K and C were also dosed. Bleeding was measured by counting and weighing compresses at the end of each surgery, and the withdrawn surgical specimens were weighed. Results: Statistically, group I patients had more bleeding than group II in all evaluated operative periods (p = 0.007). There was no significant change in the coagulogram or decrease in coagulation factors that could be associated with increased bleeding in any of the analyzed groups. Thromboelastography, which provides a comprehensive analysis of thrombin generation and of hemostasis in real time, did not differ between groups. Vitamin K was significantly increased in group I patients (p = 0.019). The weight of the surgical specimens removed was significantly higher in group I (p = 0.007) and there was correlation of the weight with the degree of bleeding. Conclusions: The results of this study demonstrate an increase of bleeding during the intraoperative period of abdominoplasty in patients with a history of gastroplasty that it is not due to changes in hemostasis.
