Background: Hepatectomies are mostly performed for the treatment of hepatic
benign or malignant neoplasms, intrahepatic gallstones, or parasitic cysts of
the liver. The most common malignant neoplasms of the liver are metastases
from colorectal cancer. Anatomic liver resection involves two or more hepatic
segments, while non-anatomic liver resection involves resection of the
metastases with a margin of uninvolved tissue. The aim of this manuscript was
to show results of hepatectomies performed at the Oncology Institute of
Vojvodina. Methods: We performed 133 liver resections from January 1997 to
December 2013. Clinical and histopathological data were obtained from
operative protocols, histopathological reports, and patients? medical
histories. Results: We did 80 metastasectomies, 51 segmentectomies, and 18
radiofrequent ablations (RFA). Average number of colorectal cancer metastases
was 1.67 per patient. We also made 10 left hepatectomies. In all cases, we
made non-anatomic resections. Conclusion: Decision about anatomic versus
non-anatomic resections for colorectal metastasis and primary liver tumors
should be made before surgical exploration. Preservation of liver parenchyma
is important with respect to liver failure and postoperative chemotherapy
treatment.
