Coagulation activation after laparoscopic cholecystectomy in spite of thromboembolism prophylaxis

Author(s): Lindberg F, Rasmussen I, Siegbahn A, Bergqvist D

Abstract

Laparoscopic cholecystectomy causes coagulation activation. There are differences in the response between patients receiving dextran and LMWH as thromboembolism prophylaxis. Since most patients are discharged the day after the operation, there could be practical as well as theoretical advantages to using dextran. Methods: Sixty-four patients undergoing LC were included prospectively. All received either dextran or low-molecular-weight heparin (LMWH). Blood samples taken the morning of the operation and the following morning were analyzed for TAT, FM, fragment 1+2, tPA, PAI-1, vWf, D-dimer, Hb, hematocrit, and APC resistance.
