Postoperative reduction of fibrinolysis as a prognostic factor of fatal outcome.

Abstract

For the resection of an esophagus carcinoma a mortality rate of 2 to 30% was described. It is still unclear whether an abdominothoracic or transhiatal intervention is superior regarding the outcome. To investigate the prognostic value of fibrinolytic markers, plasmin-alpha2-antiplasmin (PAP) and D-dimer (DD) values were determined daily in the early postoperative period for 11 days. In addition, the course of PAP and DD concentrations was compared with the method of esophagectomy. Of the 28 patients enclosed in the study, 5 died between day 10 and day 34 owing to adult respiratory distress syndrome and septicemia. The PAP and DD concentrations increased in survivors after surgery until day 5 and day 7, respectively. The concentrations were twofold and 10-fold higher than the upper reference level. In contrast, four of five nonsurvivors showed an inadequate increase in PAP concentrations within the reference range, whereas the course of DD was inconspicuous. The sensitivity and specificity of PAP and DD in respect to a fatal outcome was calculated by receiver operating characteristic analysis based on all results: sensitivity 76% (PAP-cut off value 760 microg/L) and 49% (DD 6 mg/L), specificity 77% and 72%, respectively. The biochemical markers showed no significant differences between the abdominothoracic and transhiatal esophagectomy. In the abdominothoracic intervention, lower PAP and higher DD concentrations were observed. The results showed that the PAP concentrations could detect a fatal outcome within the first 5 days after surgery.
