Impacts of laparoscopic hysterectomy on functions of coagulation and fibrinolysis system.

The main objective of the study is to compare the impacts of laparoscopic hysterectomy and total abdominal hysterectomy on the functions of coagulation and fibrinolysis system. Seventy-five patients who had undergone hysterectomy were randomly divided into laparoscopic hysterectomy group (n = 38) and total abdominal hysterectomy group (n = 37). The prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), fibrinogen, D-dimer, von Willebrand factor, α-granule membrane protein-140, thrombin-activated fibrinolysis inhibitor (TAFI) and platelet count were detected at preoperative 24 h (N0), postoperative 24 h (N1) and postoperative 48 h (N2). Compared with N0, values of PT, APTT and TT were significantly decreased at N1 in both groups, whereas von Willebrand factor, platelet count and α-granule membrane protein-140 levels at N1 were significantly increased (P < 0.05). There was no significant difference between N0 and N2 (P > 0.05). Compared with N0, fibrinogen, D-dimer and TAFI levels in both groups were significantly higher at N1 (P < 0.05), and there was no significant difference between N0 and N2 (P > 0.05). The intergroup comparison showed no significant difference of above indexes between two groups (P > 0.05). The univariate analysis showed that TAFI was negatively correlated with TT (r = -0.365, P < 0.01), APTT (r = -0.183, P < 0.05) and PT (r = -0.121, P < 0.05), whereas not correlated with other indicators. Laparoscopic hysterectomy may increase the risk of postoperative venous thrombosis.
