Medical Histories

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.

e15009 Background: The treatment of hepatic colorectal cancer metastases is increasingly multi-modal. Preoperative chemotherapy may be associated with steatohepatitis, which may increase morbidity in patients undergoing resection. Our objective was to determine if preoperative chemotherapy is associated with steatohepatitis and to determine which agents confer the greatest risk. Materials and Methods: 149 patients who had undergone liver resection or biopsy for hepatic colorectal cancer metastases were identified from an institutional database. Surgical specimens were assessed for percent steatosis and the presence of steatohepatitis as defined by the Kleiner score. The medical record was reviewed for details of preoperative chemotherapy and post-operative course. The association of preoperative chemotherapy with steatosis and steatohepatitis was assessed. Preoperative non-contrast CT scans were reviewed for evidence of steatosis as determined by the radiographic liver/spleen (L/S) ratio. The association of the L/S ratio with the presence of steatohepatitis was determined. Post-operative outcome was compared in patients with and without steatohepatitis. Results: The mean age of the population was 60.8 ±11.6 years, 56% of patients were male, and 37% of patients received preoperative chemotherapy. Steatohepatitis was identified in 45.7% of specimens. There was no statistically significant difference in the rate of steatohepatitis (59% vs. 50%, p=0.49) or percent steatosis (37% vs. 32%, p=0.29) with or without preoperative chemotherapy. No individual agent predicted a greater risk of steatohepatitis or a greater degree of steatosis. There was no significant difference in the L/S ratio in patients with or without steatohepatitis (p=NS). In patients undergoing liver resection, there was no difference in total ICU stay, blood loss, total surgery time or total length of stay between the steatohepatitis and non-steatohepatitis groups. Conclusions: Although steatohepatitis remains a potential complication of systemic chemotherapy in surgical patients with hepatic colorectal metastases, the risk and impact of chemotherapy associated steatohepatitis have not been significant in our patient population. No significant financial relationships to disclose.
