[Limitation of blood transfusions during hepatectomies. Study of 150 consecutive hepatic resections on healthy and pathological livers].
OBJECTIVE
Over the last 5 years, a policy to limit blood transfusions has been adopted in patients undergoing liver resection. The aim of this retrospective study was to report the results of 150 liver resections performed during this period.


METHODS
There were 63 major (42%) and 87 minor hepatectomies (58%). Resection was performed for malignant lesions in 64% of the patients. Vascular exclusion of the liver was used in large (> or = 10 cm) tumors and those located at the cavohepatic junction. Clamping of the portal triad or selective clamping of the pedicle of the portal lobe was used in peripheral lesions < 10 cm in diameter. Anesthesia was adapted to the type of vascular clamping and blood transfusions were deliberately limited. Red blood cells were transfused to maintain the hematocrit level above 25% in healthy patients and above 30% in patients with risk of coronary artery disease.


RESULTS
Ninety three patients (62%) did not receive blood transfusions. Three patients received more than 10 units of packed red blood cells (2%). 48% of patients with major hepatectomies and 72% with minor hepatectomies were not transfused. The rate of non transfused patients was 93% for benign lesions and 44% for malignant lesions. The presence of pathologic changes in non-tumor liver parenchyma did not influence the need for transfusions. Hospital mortality was 3% (5/150). There was no mortality in patients with normal non-tumorous livers, 14% in the presence of cirrhosis, and 12% in the presence of obstructive jaundice or steatosis > 50%. The specific morbidity rate was 7% in patients with normal livers and 54% in patients with abnormal livers.


CONCLUSIONS
This series shows that more than 60% of liver resections can be performed without blood transfusions. These results require an appropriate surgical technique and collaboration between anesthesiologist and surgeon. Thus hepatectomies in normal non-tumorous livers can be performed without mortality. In contrast, the presence of abnormalities of the non-tumorous liver parenchyma remains a major risk factor.
