title: [Changes in the hemostatic system after laparoscopic cholecystectomy].
abstract: A 30 degrees reverse Trendelenburg position and the pneumoperitoneum performed in patients undergoing at Laparoscopic Cholecystectomy (LC) cause haemodynamic modifications in inferior cava vein and in femoral veins producing a venous stasis in lower limbs. So that activation of coagulation with hypercoagulability occurs. The aim of this study is to value the modification of the haemocoagulative and fibrinolytic factors during LC and OC. 18 patients with symptomatic and non complicated lithiasis were examined. They were divided in two groups, nine patients for each group. LC was performed in first group and OC in the other group. Prothrombin time (PT), plasma-activated partial thromboplastin time (PTT), Antithrombin III (AT III) fibrinogen degradation products (FDP) were valued before and at 6, 12, 24, 48 hours after operation. For the statistical analysis Student "t" for average comparison was used. There were no relevant alterations of PT, PTT and ATIII after operation in the two groups. FP was increased after surgery, especially at 24th-48th hours in the group in which OC (p < 0.05) was performed. FDP were increased in both groups but only at 24 and 48 hour after OC (p < 0.05) the result was significant. Earlier mobilization and reduced invasivity of laparoscopy could contrast thrombotic effects of the blood stasis in the lower limbs when 30 degrees-45 degrees reverse Trendelenburg and pneumoperitoneum are performed.
