Abstract
BACKGROUND Liver resections (LRs) are performed with increasing frequency for metastatic disease. To minimize the risk of postoperative complications, a period of 6 weeks between the last dose of chemotherapy and LR is typically recommended. The current study examines postoperative morbidity and mortality following LR in patients who received chemotherapy within 30 days prior to LR. METHODS The merged 2005-2007 National Surgical Quality Improvement Program (NSQIP) Participant Use File was queried for perioperative risk factors, laboratory values and postoperative occurrences or complications in patients who underwent LR. Patients were grouped according to their receipt or non-receipt of chemotherapy within 30 days prior to LR and major postoperative complications. RESULTS A total of 2331 patients underwent LR; 2147 did not receive chemotherapy within 30 days of resection (No Chemo group) and 184 received chemotherapy within 30 days prior to resection (Chemo group). The groups were similar with regard to preoperative co-morbidities and operative factors. The median NSQIP statistically computed morbidity probability was similar between the groups (No Chemo 0.32, Chemo 0.34; P= 0.07), whereas the median mortality probability was higher in the Chemo group (0.02) than the No Chemo group (0.014; P= 0.001). Thirty-day survival was similar between the two groups (No Chemo 97%, Chemo 98%; P= 0.44). Major complication rates did not differ between the groups (No Chemo 20%, Chemo 18%; P= 0.51). Factors associated with major complications in the Chemo group included: extent of resection; intraoperative transfusion; preoperative ascites, and preoperative haematocrit. DISCUSSION Major morbidity was not increased in Chemo patients. The strongest predictors of major postoperative complications in the Chemo group were extent of resection and intraoperative red cell transfusion. Although the NSQIP dataset does not include data about tumour type or chemotherapy regimen, these data suggest that LR may be safely performed within 30 days of chemotherapy, thereby minimizing the length of time during which patients do not receive systemic treatment.

Abstract
INTRODUCTION Multimodal therapies (especially surgery of metastases and "aggressive" chemotherapy) in patients with metastases of colorectal cancers (CRC) are increasingly performed and may provide long-term survival in selected patients with more than one location of metastases. In the current literature, there are only few studies with relatively low patient numbers reporting on the outcome after resection of both hepatic and pulmonary metastases of CRC. We therefore evaluated survival of patients who underwent sequential resection of hepatic and pulmonary metastases under potentially curative intention. MATERIAL AND METHODS From 1987 until 2006, 44 patients (32% female; median age, 58 years) with hepatic and pulmonary CRC metastases underwent resections at both metastatic sites. The primary CRCs were in 50% rectal and in 50% colonic carcinomas (61% node positive, all with free resection margins). Metastases occurred synchronously (regarding primary CRC) in 32% of the patients. In 86%, liver resection was performed prior to pulmonary resection. The first resection of metastases was performed a median of 16 months after resection of the primary CRC; the median interval between the first and the second resection of metastases was 7 months. Forty-seven percent of the patients also underwent at least a third metastasectomy. During resection of the first and second site of metastases, free margins were achieved in 98% and 95%, respectively. Survival analysis was performed using Kaplan-Meier and Cox regression methods. RESULTS The 5-year survival rates (SV) were 64% after initial surgery of CRC, 42% after the first resection of metastases, and 27% after the last metastasectomy. Patients with synchronous metastases had a 5-year SV after first metastasectomy of 43% and in patients with metachronous metastases of 41% (n.s.). The location of the primary tumor (20% 5-year SV in rectal vs. 57% in colonic cancer; p < 0.02) and the lung as primary site of metastatic disease (5-year SV 0% vs. 60% in patients with primarily hepatic metastases only; p < 0.001) significantly influenced survival in univariate analysis. Patients with rectal cancer had a significantly higher frequency of the lung as first metastatic site (46%) compared to patients with colonic cancer (14%; p < 0.03). Multivariate survival analysis revealed the lung as first metastatic site and as the sole significant independent factor for the outcome (p < 0.001; relative risk vs. liver first metastases 4.7). CONCLUSION In selected patients with metastasized CRC resection of both hepatic and pulmonary metastases may improve survival rates or even provide long-term survival. Patients with lung as the first site of metastatic disease (either lung only or in combination with hepatic metastases) have a significantly worse outcome than patients with metastases primarily confined to the liver.

Abstract
BACKGROUND The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) was started in 2004. Presently, 58% of the 198 hospitals participating in ACS-NSQIP are academic or teaching hospitals. In 2008, ACS-NSQIP initiated a number of changes and made risk-adjusted data available for use by participating hospitals. This analysis explores the ACS-NSQIP database for utility in developing hepato-pancreato-biliary (HPB) surgery-specific outcomes (HPB-NSQIP). METHODS The ACS-NSQIP Participant Use File was queried for patient demographics and outcomes for 49 HPB operations from 1 January 2005 through 31 December 2007. The procedures included six hepatic, 16 pancreatic and 23 complex biliary operations. Four laparoscopic or open cholecystectomy operations were also studied. Risk-adjusted probabilities for morbidity and mortality were compared with observed rates for each operation. RESULTS During this 36-month period, data were accumulated on 9723 patients who underwent major HPB surgery, as well as on 44,189 who received cholecystectomies. The major HPB operations included 2847 hepatic (29%), 5074 pancreatic (52%) and 1802 complex biliary (19%) procedures. Patients undergoing hepatic resections were more likely to have metastatic disease (42%) and recent chemotherapy (7%), whereas those undergoing complex biliary procedures were more likely to have significant weight loss (20%), diabetes (13%) and ascites (5%). Morbidity was high for hepatic, pancreatic and complex biliary operations (20.1%, 32.4% and 21.2%, respectively), whereas mortality was low (2.3%, 2.7% and 2.7%, respectively). Compared with laparoscopic cholecystectomy, the open operation was associated with higher rates of morbidity (19.2% vs. 6.0%) and mortality (2.5% vs. 0.3%). The ratios between observed and expected morbidity and mortality rates were <1.0 for hepatic, pancreatic and biliary operations. CONCLUSIONS These data suggest that HPB operations performed at ACS-NSQIP hospitals have acceptable outcomes. However, the creation of an HPB-NSQIP has the potential to improve quality, provide risk-adjusted registries with HPB-specific data and facilitate multi-institutional clinical trials.

Abstract
OBJECTIVE To investigate independent contributions of obesity, diabetes, and smoking to resource utilization in patients following liver resection. SUMMARY BACKGROUND DATA Despite being highly resource-intensive, liver resections are performed with increasing frequency. This study evaluates how potentially modifiable factors affect measures of resource utilization after hepatectomy. METHODS The American College of Surgeons' National Surgical Quality Improvement Program (ACS NSQIP) public-use database was queried for patients undergoing liver resection. Resource variables were operative time (OT), intraoperative transfusion, length of stay (LOS), ventilator support at 48 hours, and reoperation. Bivariable and multivariable linear and logistic regressions were performed. RESULTS There were 1029 patients identified. Most resections involved less than a hemiliver (599 patients, 58.2%). Mean BMI was 28.0 +/- 6.0. Mean OT was 253 +/- 122 minutes (range, 27 to 794) but varied by procedure (P < 0.001). Mean LOS was 8.7 +/- 10.7 days (range, 0 to 202). Morbid obesity added 48 minutes to OT (P = 0.018), 1.1 units to transfusions (P = 0.049), 2.2 days to LOS (P < 0.001), and accounted for delayed ventilator weaning (odds ratio, 4.5; P = 0.022). Underweight patients had shorter OT, but stayed 3.3 days longer than normal weight patients (P < 0.001). Insulin-treated patients with diabetes had longer OT (P < 0.001), increased transfusions (P < 0.001), and delayed ventilator weaning (odds ratio, 6.7; P < 0.001), while orally-treated patients with diabetes showed opposite trends. Smokers stayed 1.9 days longer (P < 0.001), with increased risk of prolonged ventilation (odds ratio, 3.3; P = 0.002) and reoperation (odds ratio, 2.3; P = 0.015). CONCLUSION Obesity, diabetes, and smoking are each associated with important components of healthcare expenditure. Education and prevention programs are needed to limit their impact on overall resource utilization.

Abstract
OBJECTIVE To compare the clinical outcome of patients undergoing liver resection under portal triad clamping (PTC) versus hepatic vascular exclusion (HVE). METHODS A systematic literature search was performed following the guidelines of the Cochrane collaboration. Randomized controlled trials (RCT) comparing PTC to any technique of HVE were eligible for inclusion. Two authors independently assessed methodological quality of included trials and extracted data on overall morbidity, mortality, cardiopulmonary and hepatic morbidity, intraoperative blood loss, transfusion rates, postoperative transaminase and bilirubin levels, prothrombin time, and hospital stay. Meta-analyses were performed using a random-effects model. RESULTS Of the 1,383 identified references, four RCTs were finally included. These trials compared PTC to selective hepatic vascular exclusion (SHVE), total hepatic vascular exclusion (THVE), and a modified technique of HVE (MTHVE), respectively. Meta-analyses revealed no significant difference in morbidity and mortality between PTC and techniques of HVE. Further analyses showed significantly reduced overall morbidity for the PTC compared to the THVE group. There was a significantly lower transfusion rate for HVE compared to PTC. CONCLUSION Hepatic vascular exclusion does not offer any benefit regarding outcome of patients undergoing hepatic resection compared to PTC alone. Further, well-designed RCTs evaluating adequate vascular control in major hepatectomy and in patients with underlying liver disease appear justified.

Abstract
PURPOSE Resection is the most effective treatment for metastatic colorectal cancer (MCRC) to the liver. However, postoperative morbidity is common and its impact on long-term oncological outcome is unclear. The objective of this study was to evaluate the impact of postoperative morbidity on the long-term outcome after liver resection for MCRC. METHODS Medical records of patients who underwent liver resection for MCRC with curative intent between 1991 and 2002 were reviewed. Patients who died of postoperative complications were excluded; operative and perioperative data, including morbidity and clinicopathological variables, were analyzed. Patients were stratified by disease extent and risk of recurrence using a clinical risk scoring system. RESULTS A total of 1067 patients were included in the study and the median follow-up period was 41 months. The overall morbidity rate was 42%; the 5-year disease-specific survival (DSS) and overall disease-free survival (DFS) rates of patients who had complications were 41% and 25%, respectively, compared with 48% and 33%, respectively, for patients who did not have complications (P = 0.0059 for DSS, P = 0.0053 for DFS). On multivariate analysis, morbidity was not an independent predictor of either DSS or DFS; however, in a subgroup of patients with low clinical risk scores, morbidity was associated with a significant reduction in both DSS and DFS. CONCLUSIONS Postoperative morbidity adversely affects long-term outcome after hepatic resection for MCRC in patients at lower risk for recurrence. Efforts aimed at reducing perioperative morbidity will not only reduce usage of resources but will likely further enhance the therapeutic benefit of resection for such patients.

Abstract
INTRODUCTION Literature-based data on mortality after hepatectomy may be misleading, as poor outcomes are less likely to be published. The objective of the current study was to compare published vs public, nationally available mortality rates after hepatic resection. MATERIALS AND METHODS A systematic MEDLINE review was conducted to identify reports of hepatectomy outcome between January 1998-December 2004. Data were analyzed to calculate literature-based mortality rate and then compared with population-based mortality rate for hepatectomy using the Nationwide Inpatient Sample (NIS) dataset. RESULTS Twenty-three publications fulfilled screening criteria. The studies included 7,073 patients who had undergone hepatic resection (46.1% within USA vs 53.9% outside USA). Most patients were male (58.6%) with median age of 56 years. Indications for hepatic resection included hepatocellular carcinoma (47.7%), metastatic disease (34.3%), or other (18.1%). Cirrhosis was present in 23.2% of patients; 46.9% patients underwent either a hemi-hepatectomy or extended resection. The literature-based mortality rate was 3.6% (US centers only, 2.8%). Analysis of NIS revealed 11,429 hepatectomy cases. After controlling for gender, age, extent of hepatectomy, hepatocellular cancer diagnosis, and presence of cirrhosis, the adjusted NIS-based perioperative mortality rate for hepatectomy was 5.6% (95% CI, 5.0-6.2%). The relative mortality after hepatectomy was 1.6-fold higher based on population-based data compared with reports from the literature (P<0.05). CONCLUSION Actual population-based mortality rates for major liver resections may be higher than those reported in the literature. Informed consent should reflect actual local and national mortality rates rather than selective reports from the literature.

Abstract
BACKGROUND A congressional mandate, which led to the formation of the National Surgical Quality Improvement Program, is now being fulfilled with the publication of general and vascular surgical outcomes comparisons between Veterans Affairs (VA) and university medical centers. A series of National Surgical Quality Improvement Program articles evaluate the effect of hospital type (VA versus university hospitals) on procedure-specific outcomes. This article focuses on liver resections. STUDY DESIGN This is a prospective cohort study of a sample of patients undergoing liver resections at 128 VA medical centers compared with 14 university medical centers from October 1, 2001, to September 30, 2004. Preoperative and intraoperative characteristics were evaluated to identify possible variables related to morbidity and mortality and possible confounders of the hospital effect. These variables were then used to identify the effect that the hospital setting might have on surgical outcomes after liver resections. RESULTS Data from 237 liver resections at VA hospitals were compared with 783 procedures performed at university hospitals. The unadjusted 30-day morbidity rate tended to be higher in the VA (university 22.6% versus VA 27.9%; p = 0.10). After risk adjustment, results were equivalent (odds ratio = 0.94; p = 0.77). Unadjusted 30-day mortality rate was significantly higher in VA hospitals (6.8% versus 2.6%; p = 0.002). After risk adjustment, there was no longer a significant difference in mortality between the two hospital systems (odds ratio = 1.62; p = 0.33). CONCLUSIONS For liver resections, the National Surgical Quality Improvement Program and Patient Safety in Surgery Study data suggest that there is no significant difference in risk-adjusted morbidity or mortality rates between VA and the university medical centers.
