Risk factors associated with intra-operative blood loss in hepatectomized patients with giant cavernous hemangioma of the liver.
OBJECTIVE
The aim of this study was to clarify risk factors associated with intra-operative blood loss in hepatectomized patients with giant cavernous hemangioma (GCH) of the liver.


METHODS
Twenty patients with GCH of the liver were treated by hepatectomy. Eleven patients with intra-operative blood loss > 2000 ml (mean: 7145 +/- 7080 m; Group 1) were reviewed retrospectively and compared to 9 patients with intra-operative hemorrhage < 2000 ml (mean: 918 +/- 429 ml; Group 2).


RESULTS
Although there were no significant differences in pre-operative AST, ALT, and ICG-15 or fibrinogen and platelets between the two groups, pre-operative total bilirubin and fibrin degradation product (FDP) in Group 1 was significantly higher than in Group 2. Mean operation time and intra-operative blood transfusion in Group 1 versus Group 2 were 433 min vs. 213 min (p < 0.0001) and 3036 ml vs. 422 ml (p = 0.0072), respectively. The weight of resected liver (r = 0.821, p < 0.0001), maximum diameter of tumor (r = 0.782, p < 0.0001) and operation time (r = 0.748, p < 0.0001) were the most highly correlated with intra-operative blood loss, followed by pre-operative total bilirubin (r = 0.605, p = 0.0038), FDP level (r = 0.576, p = 0.0068) and intra-operative blood transfusion (r = 0.561, p = 0.0089).


CONCLUSIONS
These findings suggest that pre-operative management to reduce the tumor size, total bilirubin and FDP levels may be essential to minimize intra-operative hemorrhage and blood transfusion.
