ABSTRACT The use of intra-operative blood transfusion has been associated with worse surgical outcome in patients undergoing liver resection for malignancy.
In a series of 127 consecutive patients who underwent partial liver resection for colorectal metastases, between July 1999 and March 2010, we studied, post-operative 90 days surgical outcome using Clavien multi-tier grading system, and the effect of a variety of related factors, including type of resection, surgical technique used, concomitant colo-rectal resection, non-tumoral hepatic histological findings, site of primary tumor, and comorbidities, on the incidence of intra-operative blood transfusion.
Patients who received blood transfusions during their liver resection were more likely to have a longer post-operative length of stay, to experience Clavien Grade IIIa or worse complication. Undergoing a major resection and the presence of portal fibrosis in the non-tumoral liver tissue were both correlated with an increase in intra-operative blood transfusions.
These clinical findings suggest that although several significant factors do not seem to influence the short-term outcome of surgery, it is important to be aware of the deleterious effects of the type of resection performed and the presence of portal fibrosis on blood loss during partial liver resection.

    ABSTRACT: As the general population is aging, surgery in elderly patients has become a major public health issue. This basic question is especially true for liver resection (LR). The aim of this study was to evaluate the operative risks of LR in the elderly. Retrospective analysis of a large recent and monocentric database of LR was performed between January 1, 2005 and May 31, 2011. Patients were categorized into three groups (<60, 60-74, and ≥75 years old) to analyze postoperative outcomes and 1-year mortality. Clinicopathologic factors likely to influence outcomes were assessed by univariate and multivariate analysis. Altogether, 1,001 consecutive LRs were performed in 912 patients (mean age 62 ± 13 years). The distribution of the LR by age was 372 (37.2 %), 477 (47.6 %), and 152 (15.2 %) in patients <60, 60-74, and ≥75 years, respectively. The overall morbidity and mortality rates were 33.3 and 2.5 %, respectively. Age ≥75 years was independently associated with postoperative mortality [odds ratio (OR) 4.75, 95 % confidence interval (CI) 1.5-15.1; p = 0.008] and 1-year mortality (OR 2.8, 95 % CI 1.2-6.6; p = 0.015). The postoperative complication rate (p = 0.216) was not increased, even for major complications (p = 0.09). The other independent risk factors for mortality were a cirrhotic liver (p = 0.017), preoperative arterial chemoembolization (p = 0.001), caval vein clamping (p = 0.001), and intraoperative blood transfusion (p = 0.044). Age beyond 75 years represent a risk factor of death after LR and should be avoided after chemoembolization or in cirrhotic patients. A specific assessment using geriatric indexes might be the key to success in this population.

    ABSTRACT: PURPOSE: Postoperative bile leakage is one of the most common complications after hepatic surgery. The relationship between the inflammatory response and postoperative bile leakage has not been fully investigated. Therefore, we retrospectively investigated the relation between postoperative peripheral blood monocyte count and bile leakage in patients with colorectal liver metastases (CRLM) after elective hepatic resection. METHODS: The study comprised 105 patients who had undergone hepatic resection for CRLM between January 2000 and March 2012. Perioperative risk factors pertinent to development of bile leakage were investigated using univariate and multivariate analyses. RESULTS: Bile leakage developed in 9 (8.6 %) of 105 patients. In multivariate analysis, intraoperative fresh frozen plasma (FFP) transfusion (p = 0.009) and lower monocyte count of the peripheral blood on postoperative day 1 (p = 0.038) were found as independent risk factors of bile leakage. CONCLUSIONS: Postoperative lower monocyte count and intraoperative FFP transfusion were associated with the development of postoperative bile leakage after elective hepatic resection in patients with CRLM.

    ABSTRACT: The aim of this study was to identify the incidence of surgical site infections (SSIs) and postoperative complications, as defined by the Clavien-Dindo classification, after hepatic resection for metastatic colorectal cancer in patients with and without associated neoadjuvant chemotherapy. A total of 181 patients were studied retrospectively. Patients were divided into two groups: the first group comprised patients with associated neoadjuvant chemotherapeutic treatment for liver metastases with a latency time <8 wk and the second group comprised patients without associated neoadjuvant chemotherapy. Variables of duration of liver surgery, length of total hospital stay, and length of postoperative hospital stay seem to be correlated with SSIs and postoperative complications, P < 0.005 and P < 0.0001, respectively. Duration of surgery is a risk factor for SSIs, with an odds ratio of 1.15, and for complications according to the Clavien-Dindo classification, with an odds ratio of 1.35. Neoadjuvant chemotherapy was not a significant risk factor for SSIs, whereas the total length of hospital stay, length of postoperative hospital stay, and duration of surgery were independent predictors of SSIs and complications according to the Clavien-Dindo classification.
