Background:
The incidence of deep vein thrombosis and pulmonary embolism following laparoscopic surgery is unknown and studies on alterations of hemostasis after laparoscopy are inconclusive.
Methods:
In this study we prospectively evaluated changes in prothrombin time (PT), activated partial thromboplastin time (aPTT), fibrinogen (Fg), antithrombin III (ATIII), prothrombin fragment F 1 + 2, beta-thromboglobulin (betaTG) and D-dimer (D-D), preoperatively and 24 h after laparoscopic surgery in 16 patients.
Results:
Comparing pre- and postoperative values, no statistical differences were observed in aPTT, F1 + 2, and ATIII measurements. Postoperative PT values increased slightly (p approximately 0.05) after surgery. Conversely, Fg, betaTG, and D-D values were statistically higher in the 24-h evaluation (p = 0.008, 0.01, and 0.045, respectively).
Conclusions:
These data suggest that laparoscopic surgery induces activation of coagulation and fibrinolytic pathways and, additionaly, betaTG elevation, which has never been reported and might account for postoperative platelet activation and a greater risk of thrombogenicity. Therefore, routine thromboembolic prophylaxis in patients undergoing laparoscopic surgery is recommended.
