Abstract
Laparoscopic surgery appears to be less traumatic to the patient than open surgery, but its influence upon coagulation and fibrinolysis is incompletely elucidated. Our aim was to measure markers of coagulation and fibrinolysis before, during. and after laparoscopic cholecystectomy (LC). Blood samples drawn on admission, on four occasions during operation as well as 2 hours after operation and on the first postoperative day in 50 patients undergoing elective LC were analyzed for prothrombin fragment 1+2 (F1+2), soluble fibrin (SF), D-dimer (DD), fibrin degradation products (FbDP), tissue-type plasminogen activator (tPA) activity and antigen, and plasminogen activator inhibitor (PAI) activity and antigen. F1+2, SF, DD, and FbDP levels increased significantly after LC. Differences between pre- and postoperative PAI and tPA levels were not significant apart from a transient increase in tPA antigen levels. tPA activity was significantly increased during operation.
