title: Modifications of coagulation and fibrinolysis mechanism in laparoscopic vs. open cholecystectomy.
abstract: OBJECTIVE
  The incidence of thromboembolic complications following laparoscopic cholecystectomy as well as the indication for prophylactic thrombophylaxis is still controversially discussed. The aim of this study is to evaluate the alterations of the coagulation and fibrinolytic mechanism after laparoscopic vs. open cholecystectomy.
  
  
  METHODS
  Forty-five patients, who were submitted to laparoscopic (LC-group, n=30) or open cholecystectomy (OC-group, n=15) were included in the study. The following parameters were measured preoperatively and 24h and 48h postoperatively: platelet count (PLT), prothrombin time (PT), partial thromboplastin time (PTT), fibrinogen (FG), d-dimers (DD) and antithrombin III (AT-III).
  
  
  RESULTS
  The preoperative values were within the normal range and did not differ between the two groups. No significant alterations were noted concerning PT and PTT. FG and PLT were significantly increased in both groups at 24h and 48h compared to the baseline values, with no statistical significant difference between them at all time points. D-dimers were significantly elevated at 24h and 48h postoperatively in both groups. The LC-group showed significantly higher AT-III levels at 24h, and significantly lower DD levels at 24h and 48h compared to the OC-group (p < 0.05).
  
  
  CONCLUSIONS
  Laparoscopic cholecystectomy seems to induce a lower activation of the hemostatic mechanism compared to open cholecystectomy.
