Abstract
Pre- and postoperative plasma levels of Prothrombin Fragment 1 + 2 (F1+2), Thrombin-antithrombin III complex (TAT), Fibrinopeptide A (FpA), Fibrin and Fibrinogen Degradation Products (FbDP, FgDP) and Soluble Fibrin (SF) were measured in 40 patients undergoing gastric surgery in order to compare patients operated for benign (n = 21) and malignant (n = 19) disease. Plasma levels of F1+2, TAT, FbDP and SF on the first postoperative day were significantly higher than before operation. F1+2 and FbDP levels were further increased one week after surgery, at which time FgDP levels were also higher than preoperatively. A significant postoperative increase in FpA levels was found only in patients with malignant disease. When age was taken into consideration, significant differences between patients with and without malignancy were found only in the late postoperative period, as cancer patients had higher FpA and FbDP levels one week after surgery and higher FbDP levels one month after discharge from hospital.
