Backgroundand
Aims:vWF-antigenhasbeenshowntobeincreased in patients with portal hypertension and to predict mortality in patients with chronic liver disease. This study aimed to assess the clinical utility of preoperative vWF-antigen levels to predict poor postoperative outcome in patients undergoing liver resection in a routine clinical setting.
Methods:
95patientsundergoingliverresectionservedasprospective exploration cohort and results were validated in an independent cohort of 133 patients for 4 different institutions. VWF-Ag was evaluated perioperativelyand postoperative outcomewas recorded.
Results:
Preoperative vWF-antigen levels significantly predicted postoperative liver dysfunction (LD, area under the curve [AUC]: 0.725, P=0.009). Furthermore, a cut-off of vWF-antigen ≥182% was defined to identify patients with a higher incidence of postoperative LDormorbidity(LD:≥182%:33.3%,<182%:5.9%,P<0.001;morbidity: ≥182%: 74.1%, <182%: 44.1%, P=0.008). We confirmed our results within a prospective validation cohort (LD: ≥182%: 20.0%, <182%: 5.2%, P=0.008; morbidity: ≥182%: 56.4%, <182%: 35.1%, P=0.015). Analyzing the entire cohort, we found that patients exceeding the cut-off suffered from a significantly increased incidence of postoperative LD, morbidity, prolonged hospitalization, intensive care unit stayand mortality.
Conclusions:
Within this study we were able to reveal and subsequently validate the potential of preoperative vWF-antigen levels to predict poor postoperative outcome in patients undergoing liver resection. As vWF-antigen is easily determined and available in most standard laboratories, it seems to be avaluable clinical marker to allow for preoperative risk-stratification of patients undergoing liver resection.
