Abstract
BACKGROUND: Liver resection constitutes the main treatment of most liver primary neoplasms and selected cases of metastatic tumors. However, this procedure is associated with significant morbidity and mortality rates. AIM: To analyze our experience with liver resections over a period of 10 years to determine the morbidity, mortality and risk factors of hepatectomy. PATIENTS AND METHODS: Retrospective review of medical records of patients who underwent liver resection from January 1994 to March 2003. RESULTS: Eighty-three (41 women and 42 men) patients underwent liver resection during the study period, with a mean age of 52.7 years (range 13-82 years). Metastatic colorectal carcinoma and hepatocellular carcinoma were the main indications for hepatic resection, with 36 and 19 patients, respectively. Extended and major resections were performed in 20.4% and 40.9% of the patients, respectively. Blood transfusion was needed in 38.5% of the operations. Overall morbidity was 44.5%. Life-threatening complications occurred in 22.8% of cases and the most common were pneumonia, hepatic failure, intraabdominal collection and intraabdominal bleeding. Among minor complications (30%), the most common were biliary leakage and pleural effusion. Size of the tumor and blood transfusion were associated with major complications (P = 0.0185 and P = 0.0141, respectively). Operative mortality was 8.4% and risk factors related to mortality were increased age and use of vascular exclusion (P = 0.0395 and P = 0.0404, respectively). Median hospital stay was 6.7 days. CONCLUSION: Liver resections can be performed with low mortality and acceptable morbidity rates. Blood transfusion may be reduced by employing meticulous technique and, whenever indicated, vascular exclusion.

Abstract
The purpose of this study was to assess the characteristics of surgical infections after hepatic resection (HR) to identify factors accounting for increased postoperative mortality. Advances in operative technique and care have decreased morbidity and mortality after HR. However, infections after HR continue to be a major contributor to postoperative morbidity and mortality. All HR done during a 7-year period were analyzed and compared to our prospective surgical infection database. Factors contributing to infectious complications and mortality were identified. HR (n = 207) were performed with an overall mortality of 5.8 per cent. Nine patients (3.3%) had 18 infections; 6 (60%) had multiple infection sites, most commonly the peritoneum, blood, or wound. Three infected patients died. Lung and line infections occurred in 2 (67%) infection-related deaths. No single comorbidity increased postoperative infection risk, but an average of 6.7 co-morbid conditions were present. All infection-related deaths were associated with ventilator-dependence. All infection-related deaths occurred after resection of a mean of four segments. Additional procedures at the time of HR, operative drains, or transfusion requirements did not impact infectious complications or mortality. Methicillin-resistant Staphylococcus sp. was isolated in all infection-related deaths. The mean time from HR to initiation of treatment was 8 days for infection survivors and 13.3 days for infection-related deaths. Infectious mortality after HR remains significant. Contributing risk factors are advanced age, multiple comorbid conditions, and extent of HR. Ventilator-dependence and delays in antibiotic therapy were associated with infectious mortality. Although gram-negative enteric infections were more common, abdominal, lung, and line infections with gram-positive cocci had higher associated mortality; especially when antibiotic resistant strains were present.

Abstract
BACKGROUND The acceptable indications for liver resection in patients with colorectal metastases have increased significantly in the last decade. It is thus becoming more difficult to ascertain the limitations for selection as the boundaries have been greatly extended. This has resulted in not only more extensive resections, but more atypical and bilobar resections. The aim of this study was to compare the outcome of patients undergoing different extent of liver resection in a specialist unit. METHODS All patients undergoing liver resection for colorectal metastases at the Royal Infirmary of Edinburgh between October 1988 and April 2001 were reviewed. Patients were allocated into one of three groups: standard group, extended group, and segmental group. Patient information was collected from a prospectively completed database. RESULTS One hundred and thirty-seven patients had liver resections for colorectal metastases during the study period. There were 69 standard hepatectomies, 41 extended resections and 27 segmental resections. CEA level was significantly lower in the segmental group(p = 0.012). There was a significant difference between the groups in terms of median operating time (p < 0.0001, Kruskal-Wallis test), operative blood loss (p = 0.006, Kruskal-Wallis test) and post-operative stay ( p = 0.036, Kruskal-Wallis test). Major post-operative complications were similar between standard and extended resections but less following segmental resection (p = 0.050. Predicted median survival was 51 months following standard resection, 23 months following extended resection and 59 months after segmental resection ( p = 0.037, log rank test), however, there was no difference between the three groups for actual 5-year survival (p = 0.662, Pearson chi-square test). CONCLUSION Morbidity and mortality rates were comparable with other previous studies as was overall survival, although survival in patients undergoing extended resections was reduced. There was an acceptable level of morbidity and mortality for all three groups. Patients undergoing segmental resection had fewer complications, shorter length of stay, and the longest median survival suggesting adequate oncological clearance. Segmental resection has a role for favourably placed tumour deposits if oncological clearance can be ensured. Extended liver resections have a role for selected patients with bilobar colorectal metastases or large solitary deposits close to the hepatic vein confluence.

Abstract
BACKGROUND Attempts at identifying prognostic factors after hepatectomy in patients with colorectal liver metastases have not achieved consensus. We investigated prognostic factors ascertainable before hepatectomy for colorectal metastasis. METHOD Clinicopathological data for 149 consecutive patients with colorectal cancer who underwent curative resection of primary lesions and metastatic liver disease at one institution were subjected to multivariate analysis concerning metastatic status and the primary lesion. RESULTS Poorly differentiated adenocarcinoma or mucinous carcinoma as the primary tumor (Poor/muc; P=0.026), marked vascular invasion by the primary tumor (V; P=0.002), bi-lobar liver metastases ( P=0.048), and short doubling time (DT) of the liver tumor ( P=0.028) were characteristics assessable before hepatectomy that independently indicated poorer survival. A four-stage classification based on these factors was related to overall ( P<0.01) and disease-free ( P<0.01) survival rates. No pattern of recurrence site was evident in stage I (patients with no risk factor). Recurrence was usually extrahepatic in stage IV (patients with Poor/muc) but favored the remnant liver in stage II (patients with bi-lobar metastases or short DT) or III (patients with V; P=0.037). Stage III showed more multiple and early hepatic recurrences than stage II, and repeat hepatectomy was less frequent ( P<0.05). CONCLUSION Pre-hepatectomy prognostic staging should help to guide treatment of liver metastases.

Abstract
At the present time, the decision to resect and the choice of the extent ofa hepatic resection are largely based on surgical judgment. The CP score is the best assessment tool we can now employ. There is uniform agreement that even segmental resections are not possible in the vast majority of Child Class B patients, CP score 7 to 9. The CP score can be augmented by radiographic testing, ICG retention testing, and by assessing tumor extent and the severity of the patient's cirrhosis at surgery. Surgeons need a simple means to assist with liver function evaluation--a test to augment the CP score. Although determining ICG retention is simple, it is questionable whether it adds to one's ability to define the poor-risk patient with better accuracy than the CP score. Abundant data exist to dispute the accuracy and reproducibility of ICG retention. That surgeons use it says more about the fervent desire to find a test that supports clinical judgment in these difficult patients than the scientific validity of the test. Whether a series of tests would better define the Child-Pugh Class A patient who is also a relatively poor risk is not clear at present. Many investigations demonstrate the correlation of various assessment tools with each other, yet nothing distinguishes them in predicting risk beyond what is learned from the CP score. In a group of CP Class A patients, the extent of the disease, the nature of underlying cirrhosis, and the extent of resection provide the clinical backdrop against which a decision for resection must be made. It may well be that one test may not do it, or that one single assessment of the ICG or the 15-minute receptor volume of GSA may be inadequate to project the nuances of liver function. Thus, 99m-Tc GSA scintigraphy will provide volumetric receptor data, as well as kinetic distribution curves, and may prove a useful test in the future. Whether GSA is ultimately to be proven useful requires a correlation of the test with actual clinical outcomes, rather than correlation with other tests or with the CP score. Discovering which patients are the poor risk Child Class A patients is the desired goal. To have value, the GSA scan must augment, not mimic, the CP score. In view of the fact that experienced surgeons appear to be astute in their ability to select patients for hepatic resection, finding a more refined test will require large numbers of patients at several centers to correlate the test results and the outcomes against the spectrum of postoperative liver failure, including death. It appears that one lesson learned from portal vein embolization is that functional liver volume can be preserved. The compensatory hyperplasia that occurs in the contralateral hepatic lobe demonstrates two important features: (1) function of the opposite lobe has been transferred when evaluated by 99m-Tc-GSA, and (2) one considerable metabolic drain on the postoperative recovery from hepatic resection (ie, liver regeneration) can be attended to before the surgery. Cirrhotic livers do regenerate, but more slowly. Thus, pregrowing the remnant section of liver eliminates one stress on liver reserves following liver resection. For hepatocellular carcinoma or metastasis in cirrhotic patients, portal vein occlusion may be the best way to improve hepatic functional reserve. ICG retention may not corroborate return-to-baseline hepatic function within 2 weeks of portal vein occlusion,but may demonstrate a return to baseline when studied 6 to 8 weeks following the procedure. 99m-Tc-GSA is presently the best means to document compensatory hyperplasia and, possibly, a shift of functional reserve to the planned remnant of a more than four-segment hepatic resection. Whether this will predict the safe outcome of resection remains to be seen.

Abstract
OBJECTIVE To examine recurrence and survival rates for patients treated with hepatic resection only, radiofrequency ablation (RFA) plus resection or RFA only for colorectal liver metastases. SUMMARY BACKGROUND DATA Thermal destruction techniques, particularly RFA, have been rapidly accepted into surgical practice in the last 5 years. Long-term survival data following treatment of colorectal liver metastasis using RFA with or without hepatic resection are lacking. METHODS Data from 358 consecutive patients with colorectal liver metastases treated for cure with hepatic resection +/- RFA and 70 patients found at laparotomy to have liver-only disease but not to be candidates for potentially curative treatment were compared (1992-2002). RESULTS Of 418 patients treated, 190 (45%) underwent resection only, 101 RFA + resection (24%), 57 RFA only (14%), and 70 laparotomy with biopsy only or arterial infusion pump placement ("chemotherapy only," 17%). RFA was used in operative candidates who could not undergo complete resection of disease. Overall recurrence was most common after RFA (84% vs. 64% RFA + resection vs. 52% resection only, P < 0.001). Liver-only recurrence after RFA was fourfold the rate after resection (44% vs. 11% of patients, P < 0.001), and true local recurrence was most common after RFA (9% of patients vs. 5% RFA + resection vs. 2% resection only, P = 0.02). Overall survival rate was highest after resection (58% at 5 years); 4-year survival after resection, RFA + resection and RFA only were 65%, 36%, and 22%, respectively (P < 0.0001). Survival for "unresectable" patients treated with RFA + resection or RFA only was greater than chemotherapy only (P = 0.0017). CONCLUSIONS Hepatic resection is the treatment of choice for colorectal liver metastases. RFA alone or in combination with resection for unresectable patients does not provide survival comparable to resection, and provides survival only slightly superior to nonsurgical treatment.

Abstract
BACKGROUND Indications for hepatectomy in patients with 4 or more hepatic colorectal metastases remain controversial. METHODS A retrospective cohort study was performed with data from 131 patients who underwent a total of 198 hepatectomies. Patients were grouped according to the number of metastases at the initial hepatectomy (analysis 1) or by the total number of metastases removed by multiple hepatectomies (analysis 2). RESULTS In analysis 1, the risk ratios for death of patients with 4 to 9 and 10 nodules to those with 1 to 3 nodules were 2.12 (95% CI, 0.99-4.23) and 7.32 (95% CI, 2.82-16.9), respectively. In analysis 2, the risk ratios for death were 1.32 (95% CI, 0.66-2.59) and 3.07 (95% CI, 1.41-6.36), respectively. These values in 106 patients with negative surgical margins were 1.52 (95% CI, 0.51-3.73) and 5.40 (95% CI, 1.25-16.5), and 1.06 (95% CI, 0.45-2.32) and 1.70 (95% CI, 0.49-4.61), respectively. In analysis 2, the 5-year survival rates of patients with 1 to 3, 4 to 9, and 10 or more nodules were 51%, 46%, and 25%, respectively. CONCLUSION Hepatic resection for patients with 4 to 9 nodules clearly is warranted. On the other hand, for patients with 10 or more tumor nodules, surgery cannot be ensured absolutely to be contraindicated in high volume centers at which the surgical mortality rate is nearly zero.

Abstract
BACKGROUND Extended hepatectomy may be required to provide the best chance for cure of hepatobiliary malignancies. However, the procedure may be associated with significant morbidity and mortality. METHODS We analyzed the outcome of 127 consecutive patients who underwent extended hepatectomy (resection of > or = 5 liver segments) for hepatobiliary malignancies. RESULTS The patients underwent extended hepatectomy for colorectal metastases (n = 86; 67.7%), hepatocellular carcinoma (n =12; 9.4%), cholangiocarcinoma (n =14; 11.0%), and other malignant diseases (n =15; 11.5%). Thirty-two left and ninety-five right extended hepatectomies were performed. Eight patients also underwent caudate lobe resection, and 40 patients underwent a synchronous intraabdominal procedure. Twenty patients underwent radiofrequency ablation, and 31 underwent preoperative portal vein embolization. The median blood loss was 300 mL for right hepatectomy and 600 mL for left hepatectomy (P = 0.02). Thirty-six patients (28.3%) received a blood transfusion. The overall complication rate was 30.7% (n = 39), and the operative mortality rate was 0.8% (n = 1). Significant liver insufficiency (total bilirubin level > 10 mg/dL or international normalized ratio > 2) occurred in 6 patients (4.7%). Multivariate analysis showed that a synchronous intraabdominal procedure was the only factor associated with an increased risk of morbidity (hazard ratio [HR], 4.9; P = 0.02). The median survival was 41.9 months. The overall 5-year survival rate was 25.5%. CONCLUSIONS Extended hepatectomy can be performed with a near-zero operative mortality rate and is associated with long-term survival in a subset of patients with malignant hepatobiliary disease. Combining extended hepatectomy with another intraabdominal procedure increases the risk of postoperative morbidity.

Abstract
BACKGROUND In patients with liver metastases from colorectal cancer, survival can be increased by hepatic resection. Treatment with hepatic arterial infusion (HAI) and systemic chemotherapy following resection may further increase survival and decrease recurrence, but may also result in hepatic and systemic toxicity. This article will address the question of whether large hepatic resections resulting in a greater loss of healthy liver predisposes patients to developing toxicity from the subsequent chemotherapeutic regimens. DESIGN Retrospective analysis of 88 patients who underwent liver resection of colorectal metastases followed by adjuvant HAI and systemic chemotherapy and whose computerized tomography (CT) scans were done at Memorial Sloan-Kettering Cancer Center (MSKCC). Liver volumes were calculated from CT scans and used to determine the percentage change in healthy liver volume between the pre- and post-operative CT scans. Hepatic and systemic toxicities were defined according to the Common Toxicity Criteria of the National Cancer Institute. RESULTS Patients experienced a mean percentage decrease in healthy liver tissue of 17% (range: 57% decrease to 32% increase) at an estimated 1 month after resection and at the initiation of chemotherapy. In a logistic regression model using percentage change in the healthy liver volume as a continuous variable, no significant association was revealed between percentage of healthy liver resected and diarrhea (P = 0.47), leukopenia (P = 0.37), neutropenia (P = 0.31), high bilirubin (P = 0.27), or alkaline phosphatase (P = 0.79). CONCLUSIONS A greater loss of healthy liver following resection of hepatic metastases from colorectal cancer does not seem to predispose to the development of toxicity from adjuvant HAI and systemic chemotherapy.

Abstract
Partial hepatectomy is a major upper abdominal operation associated with certain stress to the patient. Successful adaptation to such stress is a prerequisite for survival. Donor hepatectomy with maximal safety is a principal concern during living donor liver transplantation. The purpose of the study was to compare the stress response by assessing cytokines and the acute-phase response induced by hepatectomy in patients with a healthy liver and those with a diseased liver. Fourteen patients undergoing partial right hepatectomy were enrolled in this study. Seven of them were donors for living related liver transplantation (group 1, or GI); the other seven were patients with hepatocellular carcinoma due to chronic hepatitis B (Child's class A) (GII). Blood samples for interleukin-6 (IL-6), tumor necrosis factor-alpha (TNFalpha), and C-reactive protein (CRP) assays were collected before the operation, at the beginning and end of the operation, and 24 and 48 hours after the operation. The data were analyzed and compared in the same group using the Friedman test and between groups using the Mann-Whitney U-test. A value of p < 0.05 was regarded as significant. Results showed that resection of the liver in patients with both healthy and disease livers leads to significant increases in IL-6 and CPR but not TNFalpha. Significantly lower levels of IL-6 before and after operation in GI patients compared to those in GII patients suggests that GI patients adapted to surgical stress more easily than did the GII patients.

Abstract
BACKGROUND Survival after resection of colorectal liver metastases may be influenced by the patient, the primary tumour and the liver metastases. Postoperative morbidity is associated with poor survival in several cancers. The aim of this retrospective study was to evaluate prognostic factors of survival after resection of colorectal liver metastases, including postoperative morbidity. METHODS From 1985 to 2000, 311 consecutive patients with liver metastases from colorectal cancer underwent resection with curative intent. Univariate and multivariate analyses were performed to assess the influence of age, sex, site and stage of the colorectal tumour, disease-free interval, number, size and distribution of metastases, type of hepatectomy, pedicular clamping, resection margin, blood transfusion, postoperative morbidity and adjuvant chemotherapy on overall and disease-free survival. RESULTS The postoperative mortality and morbidity rates were 3 and 30 per cent respectively. The 3- and 5-year overall survival rates were 53 and 36 per cent respectively. Both overall and disease-free survival rates were independently associated with nodal status of the colorectal tumour, number of metastases and postoperative morbidity. Patients with postoperative morbidity had an overall and disease-free 5-year survival rate half that of patients with no morbidity: 21 versus 42 per cent for overall survival (P < 0.001) and 12 versus 28 per cent for disease-free survival (P = 0.001) respectively. CONCLUSION Long-term survival can be altered by postoperative morbidity after resection of colorectal liver metastases by increasing the risk of tumour recurrence. This justifies optimizing the surgical treatment of colorectal liver metastases to decrease postoperative morbidity and the use of efficient adjuvant treatments in patients with postoperative morbidity.

Abstract
OBJECTIVE To determine if transfusion affected perioperative and long-term outcome in patients undergoing liver resection for metastatic colorectal cancer. SUMMARY BACKGROUND DATA Blood transfusion produces host immunosuppression and has been postulated to result in adverse outcome for patients undergoing surgical resection of malignancies. METHODS Blood transfusion records and clinical outcomes for 1,351 patients undergoing liver resection at a tertiary cancer referral center were analyzed. RESULTS Blood transfusion was associated with adverse outcome after liver resection. The greatest effect was in the perioperative course, where transfusion was an independent predictor of operative mortality, complications, major complications, and length of hospital stay. This effect was dose-related. Patients receiving one or two units or more than two units had an operative mortality of 2.5% and 11.1%, respectively, compared to 1.2% for patients not requiring transfusions. Transfusion was also associated with adverse long-term survival by univariate analysis, but this factor was not significant on multivariate analysis. Even patients receiving only one or two units had a more adverse outcome. CONCLUSIONS Perioperative blood transfusion is a risk factor for poor outcome after liver resection. Blood conservation methods should be used to avoid transfusion, especially in patents currently requiring limited amounts of transfused blood products.

Abstract
OBJECTIVE To determine if transfusion affected perioperative and long-term outcome in patients undergoing liver resection for metastatic colorectal cancer. SUMMARY BACKGROUND DATA Blood transfusion produces host immunosuppression and has been postulated to result in adverse outcome for patients undergoing surgical resection of malignancies. METHODS Blood transfusion records and clinical outcomes for 1,351 patients undergoing liver resection at a tertiary cancer referral center were analyzed. RESULTS Blood transfusion was associated with adverse outcome after liver resection. The greatest effect was in the perioperative course, where transfusion was an independent predictor of operative mortality, complications, major complications, and length of hospital stay. This effect was dose-related. Patients receiving one or two units or more than two units had an operative mortality of 2.5% and 11.1%, respectively, compared to 1.2% for patients not requiring transfusions. Transfusion was also associated with adverse long-term survival by univariate analysis, but this factor was not significant on multivariate analysis. Even patients receiving only one or two units had a more adverse outcome. CONCLUSIONS Perioperative blood transfusion is a risk factor for poor outcome after liver resection. Blood conservation methods should be used to avoid transfusion, especially in patents currently requiring limited amounts of transfused blood products.

Abstract
Hepatic colorectal metastases present a challenging problem in patients with recurrent colorectal cancer. Twenty percent of patients with recurrence will have liver metastases as a component of their disease, and only 10% of these patients will have isolated liver metastases that are resectable. Although systemic chemotherapy alone has not proven efficacious in the treatment of liver metastases, a number of options exist in managing these lesions. For those that are resectable, surgery remains the optimal treatment, with an expected 5-year survival rate of 33%-39% based on several large series. Hepatic artery chemotherapy is another adjunct treatment in patients undergoing resection and may further improve survival. This benefit may be even more pronounced when combined with systemic chemotherapy. Newer-generation agents are likely to further improve results. More recently, new therapeutic modalities have been used to treat unresectable lesions. These include hepatic artery chemotherapy and ablative techniques such as radiofrequency ablation and cryoablation. This article will highlight the data regarding hepatic resection for colorectal metastases, describe the rationale for and efficacy of hepatic arterial chemotherapy in the postoperative adjuvant setting and in unresectable liver disease, and review the current literature describing ablative techniques in the treatment of liver metastases.

Abstract
BACKGROUND Bile leaks are a major cause of morbidity and mortality after liver resection. Endoscopic stent insertion is the treatment of choice, although the optimal timing of stent placement has not been established. This study reviewed the outcome of early endoscopic biliary stent insertion for treatment of bile leaks after hepatic resection. METHODS One hundred fifteen patients underwent hepatic resection in a single unit from July 1995 to December 2000. The type of liver resection, clinical presentation of bile leaks, findings on ERCP, and outcomes after stent placement were recorded. RESULTS Twenty patients (17%) had bile leaks; 15 had bile in surgical drains but were asymptomatic, and 5 had clinical evidence of a subphrenic collection. In one patient the leak closed spontaneously. The remaining 19 patients underwent ERCP. Fifteen had a leak from a peripheral biliary radical and an endoscopic stent was inserted. Two had a hepatic duct stump leak and were treated by nasobiliary drainage followed by stent insertion. In the remaining 2 patients cholangiography did not demonstrate a leak but a plastic stent was inserted. ERCP was performed a median of 6 days (range 5 to 10 days) after surgery. There was no ERCP-related complication. Median hospital stay in the 95 patients without a bile leak was 10 days (range 4-30 days) compared with 15 days (range 10-41 days) for those with bile leaks (NS). Stents were removed endoscopically at 6 weeks with no persistent leaks detected. There were no late biliary complications (median follow-up 26 months, range 12-72 months). CONCLUSIONS Early endoscopic biliary stent insertion is effective in the management of bile leakage after hepatic resection.

Abstract
BACKGROUND Bile leak is a serious complication following major hepatic surgery. It is associated with significant mortality rates if reoperative management is attempted. We evaluated our experience with aggressive, nonoperative management of postoperative biliary complications. METHODS All medical records of patients undergoing major liver resection, cryosurgery or radiofrequency ablation from September 1996 through March 1999 were reviewed. RESULTS Seventy-four patients were identified, and 9 (12%) developed bile leaks. Biliary leaks were investigated with endoscopic retrograde cholangiopancreatography (ERCP) and treated with endoscopic stenting when possible. The bile leak was found to originate from the resected duct stump or ablated surface of the liver in all cases. Patients were treated with ERCP stent placement (5), computed tomography-guided percutaneous drainage (3), and hepaticojejunostomy "chimney" (1). Six of 9 patients had resolution of their bile leak with the mean time of removal of the drain of 4.7 months. There was only 1 death, and that patient died nearly 3 months after surgery from complications not directly related to the bile leak. CONCLUSIONS Bile leak after liver resection can be managed nonoperatively in most cases with a combination of percutaneous drain placement and biliary stenting. Most bile leaks will close with time, although a drain may be required for many months.

Abstract
Hepatic metastases occur in 60% of patients following resection for colorectal cancer. Liver resection is the only curative option, with one third of resected patients alive at five years. In those developing recurrence in the liver following resection, further liver surgery may be curative, with similar 5 years survival rates of about 30%. Until recently surgery was feasible in only 15-25% of patients with colorectal liver metastases. New strategies, such as downstaging chemotherapy, portal vein embolization and two-stage hepatectomy, may increase the resectability rate by 15%. Earlier detection of liver metastases would increase resectability, although good follow-up trials are lacking. Once suspected, colorectal liver metastases are staged by spiral CT, CT portography and MRI, which have similar overall accuracies. Mortality following liver resection is less than 5% in major centres, with a morbidity rate of 20% to 50%. Prognostic scoring systems can be used to predict the likely cure rate with resection. Pulmonary metastases occur in 10-25% of patients with resected colorectal cancer, but are limited to the lung in only 2% of cases. In these selected cases surgery provides long-term survival in 20-40%, and repeat lung resection has shown similar rates. For patients with unresectable disease, chemotherapy and ablation techniques have been demonstrated to prolong survival, although chemotherapy alone has been shown to improve quality of life.

Abstract
A retrospective study was performed to define patient selection, safety, and efficacy of hepatic resection for colorectal metastases. The recently proposed preoperative clinical risk score (CRS) for selection of patients for surgery was also assessed. In all, 146 consecutive hepatic resections in 137 patients operated in the period between 1977 and 1999 were studied. Of these patients, 113 were classified into five CRS groups. Perioperative mortality was 1.4% (2 patients; no death in 120 patients operated after 1985) and morbidity was 38%. Five-year actuarial survival (perioperative mortality included) was 29% (median 37 months), and actual 5-year survival was 25% (17/69 patients). Patients operated after 1995 lived longer than those operated before 1995. Multiple regression analyses identified preoperative carcinoembryonic antigen CEA <100 mg/L, nodal status at resection of primary tumor, and R0 vs. R1/R2 resection as prognostic parameters. CRS grouping had prognostic importance. The relative risk (hazard rate) of tumor recurrence in patients with CRS 3-4 was 2.1, compared to that of patients with CRS 0-2. Five-year actuarial survival in the two groups was 12% and 40%, respectively. Fourteen of 15 long-term survivors (>5 years) classified by the CRS system had CRS of 2 or less. Resection for colorectal liver metastases is safe, and long-term survival rates are acceptable. CRS predicts patient outcome, but the clinical role in patient selection will have to be defined in prospective studies.

Abstract
AIM: To study local therapeutic efficacy, side effects, and complications of radiofrequency ablation (RFA), which is emerging as a new method for the treatment of patients with hepatocellular carcinoma (HCC) with cirrhosis or chronic hepatitis and metastatic liver cancer.
METHODS: Thirty-six patients with primary and secondary liver cancers (21 with primary hepatocellular carcinoma, 12 with colorectal cancer liver metastases and 3 with other malignant liver metastases), which were considered not suitable for curative resection, were include in this study. They were treated either with RFA (RITA2000, Mountain View, California, USA) percutaneously (n = 20) or intraoperatively (n = 16). The procedures were performed using the ultrasound guidance. The quality of RFA were based on monitoring of equipments and subject feeling of the practitioners. Patients treated with RFA was followed according to clinical findings, radiographic images, and tumor markers.
RESULTS: Thirty-six patients underwent RFA for 48 nodules. RFA was used to treat an average 1.3 lesions per patient, and the median size of treated lesions was 2.5 cm (range, 0.5-9 cm). The average hospital stay was 5.6 d overall (2.8 d for percutaneous cases and 7.9 d for open operations). Seven patients underwent a second RFA procedure (sequential ablations). Sixteen HCC patients with a high level of alpha fetoprotein (AFP) and 9 colorectal cancer liver metastases patients with a high level of serum carcinoembryonic antigen (CEA) have a great reduction benefited from RFA. Four (11.1%) patients had complications: one skin burn; one postoperative hemorrhage; one cholecystitis and one hepatic abscess associated with percutaneous ablations of a large lesion. There were 4 deaths: 3 patients died from local and system diseases (1 at 7 month, 1 at 9 month, and 1 at 12 month), 1 patients died from cardiovascular shock, but no RFA-related death. At a median follow-up of 10 mo (range, 1-24 mo), 6 patients (16.7%) had recurrences at an RFA site, and 20 patients (56.7%) remained clinically free of disease.
CONCLUSION: RF ablation appears to be an effective, safe, and relatively simple procedure for the treatment of unresectable liver cancers. The rate and severity of complications appear acceptable. However, further study is necessary to assess combination with other therapies, long-term recurrence rates and effect on overall survival.

Abstract
Bile leakage after hepatic resection often results in the formation of a biliary-cutaneous fistula. Such a fistula, when caused by an isolated bile duct in the remnant liver, can be intractable. We report a successful case of ethanol injection therapy of an isolated bile duct. A 73-year-old man underwent right hepatic resection for hepatocellular carcinoma. Bile leakage occurred after surgery, and the patient developed a biliary-cutaneous fistula. Fistulography revealed an isolated bile duct in the remnant portion of the caudate lobe without communication to the main biliary system. As conservative management with simple drainage was ineffective, injection therapy with ethanol was performed with a balloon occlusion catheter. After 11 therapy sessions, the bile duct was eradicated, and the biliary- cutaneous fistula was completely healed. The post-treatment course was uneventful. Ethanol injection therapy can be a choice for management of patients with a biliary fistula caused by an isolated bile duct.

Abstract
Follow-up after curative treatment of patients with colorectal cancer has as its main aims the quality assessment of the treatment given, patient support, and improved outcome by the early detection and treatment of cancer recurrence. How often, and to what extent, the final aim, improved survival, is indeed realised is so far unclear. A literature search was performed to provide quantitative estimates for the main determinants of the effectiveness of the follow-up. Data were extracted from a total of 267 articles and databases, and were aggregated using modern meta-analytic methods. In order to provide one more colorectal cancer patient with long-term survival through follow-up, 360 positive follow-up tests and 11 operations for colorectal cancer recurrence are needed. In the remaining 359 tests and 10 operations, either no gains are achieved or harm is done. As the third aim of colorectal cancer follow-up, improved survival, is realised in only few patients, follow-up should focus less on diagnosis and treatment of recurrences. It should be of limited intensity and duration (3 years), and the search for preclinical cancer recurrence should primarily be performed by carcino-embryonic antigen (CEA) testing and ultrasound (US). The focus of colorectal cancer follow-up should shift from the early detection of recurrence towards quality assessment and patient support. As support that is as good or even better can be provided by a patient's general practitioner (GP) or by specialised nursing personnel, there is no need for routine follow-up to be performed by the surgeon.

Abstract
Approximately 50% to 60% of patients with colorectal cancer will develop hepatic metastases during the course of their illness, with 20% to 30% of patients having liver metastases at time of diagnosis. In nearly a quarter of these patients the liver is the only site of disease. Surgical resection of isolated hepatic metastases has been associated with a 27% to 37% 5-year survival and confers a survival advantage compared to patients not undergoing resection. Thorough preoperative and intraoperative evaluation is necessary to select appropriate surgical candidates who may benefit from resection. This article examines criteria useful in patient selection, and also reviews the management of recurrent hepatic metastases and the role of repeat hepatic resection.

Abstract
BACKGROUND Liver metastases are a major cause of death in patients with colorectal carcinoma. The only curative option available at present is surgery. This review article discusses the current state of evidence for the effectiveness of liver resection for patients with liver metastases from colorectal cancer. METHODS Medline, Embase, Current Contents and Science Citation Index databases were used to search English language articles published on the subject of liver resection for colorectal metastases in the last 20 years. RESULTS Liver resection has a five year survival of 16-49% and 10 year survival of 17-33% with an operative mortality rate of 0-9%. Two factors appear to be clearly associated with poorer outcome - involved resection margins and the presence of extrahepatic disease (including hilar and coeliac axis lymph nodes) at the time of liver resection. None of the other factors related to the patients, their primary tumour or the metastases themselves have been conclusively shown to adversely effect long-term survival. CONCLUSIONS Liver resection is a feasible, safe and effective procedure which carries an acceptable morbidity and mortality and does have a major impact on the survival of these patients. The decision on resectability of colorectal metastases should be decided by the ability to leave at least 2-3 segments of liver free from metastases with uninvolved resection margins, together with the general fitness of the patient to undergo a major surgical procedure.

Abstract
Liver metastasis represents the major cause of death of patients who have been treated for colorectal adenocarcinoma. Spontaneous survival rarely exceeds two years. Surgery can offer long-term survival and resection should be considered when liver metastases can be totally resected with clear margins and when there is no non-resectable extra-hepatic disease. The choice between anatomical or wedge resection depends on the number and the location of the metastases but does not influence survival. Clamping methods limit blood loss. Operative mortality is generally less than 5%. The five-year survival rate after surgical resection varies from 20% to 45% according to several prognostic factors. The longer survival is observed in patients with fewer than four lesions, with lesions smaller than 4 cm, without extra-hepatic disease, with lesions that appeared more than two years after the resection of a stage I or II colorectal cancer and whose CEA level is normal. After resection, follow-up can detect hepatic recurrence that can be treated with repeat hepatectomy. The efficacy of systemic chemotherapy using new agents can increase the number of patients amenable to surgery. Regional therapies with cryotherapy or radiofrequency ablation can help to treat unresectable or non-totally resectable lesions and may improve survival. The effects on survival of adjuvant treatments, including pre- or postoperative systemic or postoperative intra-arterial chemotherapy, are currently under evaluation.

Abstract
BACKGROUND Major liver trauma has a high mortality because of immediate exsanguination and a delayed morbidity from septicemia, peritonitis, biliary fistulae, and delayed secondary hemorrhage. We evaluated laser soldering using liquid albumin for welding liver injuries. METHODS Fourteen lacerations (6 x 2 cm) and 13 nonanatomic resection injuries (raw surface, 8 x 2 cm) were repaired. An 805-nm laser was used to weld 53% liquid albumin-indocyanine green solder to the liver surface, reinforcing it by welding a free autologous omental scaffold. The animals were heparinized and hepatic inflow occlusion was used for vascular control. For both laceration and resection injuries, 16 soldering repairs were evaluated acutely at 3 hours. Eleven animals were evaluated chronically, two at 2 weeks and nine at 4 weeks. RESULTS All 27 laser mediated-liver repairs had minimal blood loss compared with the suture controls. No dehiscence, hemorrhage, or bile leakage was seen in any of the laser repairs after 3 hours. All 11 chronic repairs healed without complication. CONCLUSION This modality effectively seals the liver surface, joins lacerations with minimal thermal injury, and works independently of the patient's coagulation status.

Abstract
BACKGROUND Advances in surgery have reduced the mortality rate after major liver resection, but complications resulting from inadequate postresection hepatic size and function remain. Portal vein embolization (PVE) was proposed to induce hypertrophy of the anticipated liver remnant in order to reduce such complications. The techniques, measurement methods and indications for this treatment remain controversial. METHODS A Medline search was performed to identify papers reporting the use of PVE before hepatic resection. Techniques, complications and results are reviewed. RESULTS Complications of PVE typically occur in less than 5 per cent of patients. No specific substance (cyanoacrylate, thrombin, coils or absolute alcohol) emerged as superior. The increase in remnant liver volume averages 12 per cent of the total liver. The morbidity rate of resection after treatment is less than 15 per cent and the mortality rate is 6-7 per cent with cirrhosis and 0-6.5 per cent without cirrhosis. Embolization is currently used for patients with a normal liver when the anticipated liver remnant volume is 25 per cent or less of the total liver volume, and for patients with compromised liver function when the liver remnant volume is 40 per cent or less. CONCLUSION This treatment does not increase the risks associated with major liver resection. It may be indicated in selected patients before major resection. Future prospective studies are needed to define more clearly the indications for this evolving technique.

During the six months before surgery the patient lost 10 kg of weight (15%). Moreover, in the postoperative period the patient received exclusively 5% dextrose solution intravenously. On the 8th postoperative day, an alteration of consciousness, a vertical nystagmus and an ataxia led to consider the diagnosis of thiamine deficiency that was then established by the decrease in the transcetolase activity of the red blood cells. Vitamin B1 supply improved the clinical status rapidly and completely. This observation allows to review aetiologies and clinical forms of thiamine shortage. In addition, it stresses the detection of exposed patients and the prevention methods.

Abstract
OBJECTIVE To identify the perioperative risk factors for postoperative bile leakage after hepatic resection, to evaluate the intraoperative bile leakage test as a preventive measure, and to propose a treatment strategy for postoperative bile leakage according to the outcome of these patients. SUMMARY BACKGROUND DATA Bile leakage remains a common cause of major complications after hepatic resection. METHODS Between January 1985 and June 1999, 781 hepatic resections without bilioenteric anastomosis were performed at the authors' institution. Perioperative risk factors related to postoperative bile leakage were identified using univariate and multivariate analysis. The characteristics of patients with intractable bile leakage and the effect of intraoperative bile leakage test were also examined. Management was evaluated in relation to the outcomes and the clinical characteristics of the patients with bile leakage. RESULTS Bile leakage developed in 31 (4.0%) of 781 hepatic resections. This complication carried high risks for surgical death (two patients [6.5%] died). The stepwise logistic regression analysis identified high-risk surgical procedure, in which the cut surface exposed the major Glisson's sheath and included the hepatic hilum (i.e., anterior segmentectomy, central bisegmentectomy, or total caudate lobectomy), as the independent predictor of the development of postoperative bile leakage. None of the 102 cases in which an intraoperative bile leakage test was performed were subsequently complicated by postoperative bile leakage, and the preventive effect of the test was statistically significant. Patients with fisterographically demonstrable leakage from the hepatic hilum and with postoperative uncontrollable ascites had poor outcomes. CONCLUSION Patients with bile leakage from the hepatic hilum and postoperative uncontrollable ascites tend to have a poor prognosis. Therefore, especially when a high-risk surgical procedure is performed in patients with liver cirrhosis, more careful surgical procedures and use of an intraoperative bile leakage test are recommended.

Abstract
OBJECTIVE To analyze the cost-effectiveness of resection for liver metastases compared with standard nonsurgical cytotoxic treatment. SUMMARY BACKGROUND DATA The efficacy of hepatic resection for metastases from colorectal cancer has been debated, despite reported 5-year survival rates of 20% to 40%. Resection is confined to specialized centers and is not widely available, perhaps because of lack of appropriate expertise, resources, or awareness of its efficacy. The cost-effectiveness of resection is important from the perspective of managed care in the United States and for the commissioning of health services in the United Kingdom. METHODS A simple decision-based model was developed to evaluate the marginal costs and health benefits of hepatic resection. Estimates of resectability for liver metastases were taken from UK-reported case series data. The results of 100 hepatic resections conducted in Sheffield from 1997 to 1999 were used for the cost calculation of liver resection. Survival data from published series of resections were compiled to estimate the incremental cost per life-year gained (LYG) because of the short period of follow-up in the Sheffield series. RESULTS Hepatic resection for colorectal liver metastases provides an estimated marginal benefit of 1.6 life-years (undiscounted) at a marginal cost of 6,742 pound sterling++. If 17% of patients have only palliative resections, the overall cost per LYG is approximately 5,236 pound sterling (5,985 pound sterling with discounted benefits). If potential benefits are extended to include 20-year survival rates, these figures fall to approximately 1,821 pound sterling (2,793 pound sterling with discounted benefits). Further univariate sensitivity analysis of key model parameters showed the cost per LYG to be consistently less than 15,000 pound sterling. CONCLUSION In this model, hepatic resection appears highly cost-effective compared with nonsurgical treatments for colorectal-related liver metastases.

Abstract
Hemorrhage and liver failure are the two greatest concerns for patients undergoing major liver resection. Inflow occlusion (Pringle maneuver) is often used to minimize blood loss, but hepatic ischemia results in an increased risk of postoperative hepatic dysfunction. We report our experience with the Harmonic Scalpel ultrasonically activated shears (UAS; Ethicon Endo-Surgery, Cincinnati, OH) and a vascular stapler for hepatic resection as technological advances that aid in minimizing blood loss and thereby reduce the need for inflow occlusion. We retrospectively reviewed liver resections performed from September 1997 through July 1998, in which the UAS and articulating vascular endoscopic linear cutting stapler were used. The vascular stapler was used to divide the appropriate portal vein branch and hepatic vein(s) before parenchymal transection. Parenchymal dissection was performed with UAS to a depth of approximately 2 to 3 cm, and the remainder of the liver parenchyma was divided by a clamp crush and clip and suture ligate technique. Patients underwent segmental resection (n = 12), lobectomy (n = 13), or extended lobectomy (n = 11). Resection was performed for metastatic disease, primary liver tumors, or benign disease in 21, 8, and 7 patients, respectively. A Pringle maneuver was performed in 7 of 36 patients (mean clamp time, 8 minutes). The median required intraoperative blood transfusion was 0 units of packed red blood cells. Major and minor complications occurred in 12 and 3 patients, respectively. Two deaths were related to pneumonia and abdominal infection. The vascular stapler safely and securely divides portal vein branches and hepatic veins. The UAS initiates parenchymal transection with minimal blood loss. These two technologies facilitate the surgeon's aim of liver resection without blood transfusion or Pringle maneuver.

Abstract
The liver is a common site of metastasis from a variety of tumors. In many cases, liver resection for metastatic cancer provides the only chance for a cure and can be performed with less than 5% mortality and acceptable morbidity. The 5-year survival following liver resection for colorectal metastasis is reported in many large series to be 25% to 37%. The data regarding liver resection for other metastatic tumor types are less clear. However, resection for selected tumors, such as neuroendocrine and renal cell, can provide durable palliation and/or cure. We will review important prognostic factors used to guide the selection of patients for resection of metastatic disease and make recommendations for imaging studies and follow-up routines. The role of adjuvant regional and systemic chemotherapy for resectable metastatic disease is also discussed. Methods for ablating unresectable metastatic tumors may prove to be useful adjuncts to current therapies.

Abstract
BACKGROUND Liver resection for colorectal metastases is the only known treatment associated with long-term survival; extrahepatic disease is usually considered a contraindication to such treatment. However, some surgeons do not regard spread to the hepatic lymph nodes as a contraindication provided that these nodes can be excised adequately. A systematic review of the literature was undertaken to address this issue. METHODS An electronic search using Medline, Cancerlit and Embase databases was performed for studies reporting liver resection for colorectal metastases from 1964 to 1999. Data were extracted from papers reporting outcome for patients with positive hepatic nodes and analysed according to predetermined criteria. RESULTS Fifteen studies were identified that gave survival data on 145 node-positive patients. Five patients were reported to have survived 5 years after liver resection; one was disease free, two had recurrent disease and the disease status was not described in the remaining two. Five studies containing 83 patients specified a formal lymph node dissection as part of the surgical procedure and four of the five node-positive 5-year survivors were from these studies. CONCLUSION There are few 5-year survivors after liver resection, with or without lymph node dissection, for colorectal hepatic metastases involving the hepatic lymph nodes.

Abstract
The transformation of liver and biliary tract surgery into a full speciality began with the application of functional anatomy to segmental surgery in the 1950's, reinforced by ultrasound and new imaging techniques. The spectrum of gall-stone disease encountered by the hepatobiliary surgeon has changed with the laparoscopic approach to cholecystectomy. There is increased need for conservation techniques to repair the bile duct injuries that arise more often in the laparoscopic approach to cholecystectomy. These and other surgical interventions on the bile ducts should be selected as a function of risk versus benefit in relation to the patient's requirements and the institutional expertise. Bile duct cancers, including hilar cholangiocarcinoma, and gallbladder cancers have a dismal reputation, but evidence is accumulating for better survivals from aggressive approaches performed by specialist hepatobiliary surgeons. Hepatic surgery has increased in safety and effectiveness, largely due to the segmental approach, but also to experience with techniques for vascular control and exclusion used in liver transplantation. Techniques such as portal vein embolisation, which induces hypertrophy of the future remnant liver, percutaneous local tumour destruction using cryotherapy or radiofrequency tumour coagulation and more effective chemotherapy are beginning to increase the number of patients who can undergo curative resection. In liver transplantation, segmental surgery has been applied to graft reduction and to split liver grafts, and is opening new perspectives for living donor transplantation. Today the limitation to survival in primary and metastatic liver cancer lies not in the surgical technique but in the difficulty of dealing with microscopic and extrahepatic disease. Progress in these fields will enable the hepatobiliary surgeon to further extend the possibilities for proposing curative resections.

Abstract
The purpose of this study was to determine the morbidity and mortality in elderly patients undergoing liver resections for metastatic colon cancer and compare them with those of a control group of younger patients. The charts of all patients undergoing liver resection for colon cancer were retrospectively reviewed. Patients less than 70 years of age (Group A) were compared with patients 70 years of age or older (Group B). Between 1971 and 1995, 167 liver resections were performed for metastatic colorectal cancer. Of these, 41 patients were in Group A and 126 patients were in Group B. The mean age of Group A was 74.5 years, and that of Group B was 57 years. American Society of Anesthesiologists (ASA) classification was similar for both groups (Groups A and B were 75.6% and 81.1% ASA class II, respectively). Anatomic resections were performed in 49 per cent and wedge resections in 51 per cent of patients in Group A, and 68 and 32 per cent in Group B, respectively. Estimated blood loss was slightly less for Group A (1575 vs 1973 cm3), as was operative time (4.0 vs 4.7 hours). In-hospital mortality rate was 7.3 per cent for Group A and 2.4 per cent for Group B. The major morbidity rates were 29 and 17.5 per cent, respectively. Intensive care unit care was necessary in 73 per cent (mean length of stay 3.9 days) for Group A and 62.6 per cent (mean length of stay 2.0 days) for Group B. The average length of hospitalization was 13.1 days for Group A and 16.6 days for Group B. The recurrence rates were similar for the two groups [56% (Group A) vs 66% (Group B)], but mean survival was longer for younger patients (22.9 vs 33.5 months). We conclude that liver resection for colorectal cancer liver metastases in properly selected patients older than 70 years of age can be performed with acceptable morbidity and mortality rates. The long-term survival for older patients is less than that for younger patients, but is still a significant length of time. Therefore, we conclude that age alone is not a contraindication to liver resection for colorectal cancer metastases in patients older than 70.

Abstract
BACKGROUND Several authors have recently reported encouraging results from low-level direct current therapy in easily accessible malignant tumors. However, antitumoral effects in colorectal metastases have not been investigated experimentally. METHODS Using an animal model with induced hepatic metastases, we analyzed the effectiveness and the tumor growth dynamics after direct current application. Three weeks after induction tumor volumes were estimated with magnetic resonance imaging (MRI). Then direct current (80 C/cm3) was applied in the treatment group by means of one anode in the tumor center and four cathodes peripherally. In the control group electrodes were placed without applying current. Tumor growth dynamics was analyzed with MRI after 3 and 5 weeks. After this all animals were killed, and the livers histologically examined. RESULTS After 5 weeks MRI showed a 1.6-fold tumor enlargement in the treatment group versus a 2.9-fold enlargement in the control group (Student t test, P=0.0051). The histopathologic analysis of the treated livers yielded a 21% complete response rate and a 78% partial response rate. No necroses were found in the control group. CONCLUSIONS These results confirm the effectiveness of low-level direct current application as a potential modality for the treatment of hepatic metastases.

Abstract
Although major progress has been achieved, particularly in the field of patient selection and postoperative intensive care, morbidity and mortality rates after major liver surgery are still significant. In fact, the mortality rate in major series reaches 30% of patients undergoing complex liver procedures, mostly related to postoperative septic events. Among these, although extra-abdominal infectious localizations are also frequently reported, intra-abdominal sepsis and abscess formation are probably the most frequent infective clinical presentations. The literature reports that the magnitude of the resection and duration of surgery are associated with a significantly higher postoperative morbidity and mortality rate. Severe postoperative infectious events cause a high proportion of this morbidity and in the presence of a septic evolution of the clinical picture the mortality rises dramatically. Such a tight association between severe infections and mortality after major hepatic surgery gives account to the fundamental role played by the liver in the metabolic homeostasis of the patient and also to the central hepatic function in the immune response to microorganisms of gastroenteric origin. After major liver surgery these central hepatic functions may by significantly impaired, thus leading to higher susceptibility to infections, in particular in the elderly. On these bases the improvement in prophylaxis protocols, in the early diagnosis and in the treatment of these postoperative infectious events can help optimize clinical results after major hepatic surgery.

Abstract
The outcome of 134 patients undergoing hepatic resection for colorectal metastasis was studied. Current follow-up was available in 98 per cent of patients, for more than 5 years in 58 patients, and totaling 360 patient-years. Patients (52% male) had an average age of 62 ± 1 years (standard error of the mean). Time lapse between the primary colon surgery and hepatic resection was a median of 16 months and a mean of 19 ± 1 months. Thirty-two (24%) were operated on within 6 months for both their primary tumor and hepatic metastasis. Intensive care unit and total hospital length of stay were a median of 1 and 7 days, respectively. Pathology reports demonstrated that on average there were 2.0 ± 0.1 lesions, with the largest lesion measuring 4.4 ± 0.2 cm. In 72 per cent of patients, the lesions were found in one lobe only. CEA was elevated in 83 per cent of patients preoperatively and was 60 ± 11 ng/mL before and 4.0 ± 0.5 ng/mL after hepatic resection. Patient survival was 81 per cent at 1 year, 50 per cent at 3 years, 36 per cent at 5 years, and 23 per cent at 10 years. Actual 5- and 10-year survival was 22 of 58 (38%) patients and 4 of 21 (19%) patients respectively. Disease-free survival was 58 per cent at 1 year, 27 per cent at 3 years, 16 per cent at 5 years, and 12 per cent at 7 years. Survival was much better for one to four lesions than for five or more lesions (P < 0.01). Several other potential risk factors did not affect survival, including whether the patient received chemotherapy after hepatic resection. There were 36 (43%) patients who recurred with hepatic involvement only, 27 (32%) including hepatic involvement and 21 (25%) with nonhepatic involvement only. There were 15 patients who went on to receive repeat hepatic resections, with a 5-year survival of 74 per cent and disease-free survival of 58 per cent. Hepatic resection provides the best outcome of any form of therapy for selected patients with isolated hepatic metastasis.

Abstract
Hepatic resection is a chance for cure for primary and secondary liver tumors and a variety of benign diseases. Despite advances in surgical technique and patient care, preoperative and postoperative morbidity in patients undergoing liver resection remains high. Because a high morbidity represents a risk factor contributing to a fatal outcome of the surgical procedure, our study aimed to investigate the contribution of different risk factors to a fatal outcome and if mortality can be predicted by the presence of certain risk factors. Two hundred fifty-seven patients undergoing hepatic resection (curative and palliative) were analyzed preoperatively, immediately after surgery, and 10 days after surgery for 60 potential risk factors. Survivors (n = 238) and nonsurvivors (n = 19) were compared univariately. The analysis identified 14 variables to differentiate between groups. These variables were processed by multivariate logistic regression analysis. Three models to estimate 30-day mortality were identified, tested for statistical accuracy, and assessed for their receiver-operated characteristics (ROCs). The variables in the multivariate models were as follows: preoperatively, age, number of comorbid factors, and presence of cirrhosis; immediately after surgery, age, number of comorbid factors, and percentage of resected liver; and 10 days after surgery, age, hours of ventilation, and number of adverse events. Goodness of fit was 0. 863, 0.912, and 0.966, respectively. Areas under the ROC curves were 83.6%, 85.7%, and 98.0%. The specificity (probability to identify survivors correctly) was greater than 90% for all models, although sensitivity (probability to identify nonsurvivors correctly) was greater than 90% only for 10 days after surgery. We conclude that logistic regression is appropriate to assess the importance of risk factors in the course of hepatic resection and to identify patient groups at high risk.

Abstract
BACKGROUND Our purpose was to determine whether the combination of total liver vascular inflow occlusion (Pringle maneuver) and rapid hepatic transection with a clamp-crush technique results in significant reduction of blood loss and transfusion requirements during major hepatic resections. METHODS A series of 49 adult patients underwent major hepatic resections for metastatic disease between April 1, 1992, and March 31, 1998. Group 1 patients (n = 15) had standard hilar dissection and finger-fracture hepatic transection without total liver inflow occlusion. Group 2 patients (n = 34) had total liver inflow occlusion and clamp-crush parenchymal transection. RESULTS Median blood loss was 1600 mL for group 1 and 500 mL for group 2 (P = .001). Eleven (73%) patients in group 1 required intraoperative blood transfusion (median 2 units) compared with 7 (21%) in group 2 with a median of 0 units (P = .001 and P < .001, respectively). Of the 7 patients in group 2 who required transfusion, 3 had a preoperative hemoglobin below 10 g/dL, 1 required splenectomy for operative injury, and 1 underwent a concomitant complicated small bowel resection. CONCLUSIONS Major hepatic resections can be performed without transfusion of blood products when preoperative hemoglobin is above 10 g/dL and concomitant major surgical procedures are not required.

Abstract
GOAL The theoretical explanation of the limits of an array transducer to coagulate large tissues volumes. METHODS A theoretical model is used to illustrate the focal limitations of a spherically sectioned array designed for the treatment of deep seated tissue, e.g. liver. The design optimizes the acoustic dose as a function of the focal depth and available acoustic aperture with the goal of coagulating large volumes in a single sonication period. A quantitative measure of the possible region of focal necrosis is modeled as a function of array parameters with the limiting criteria being near field heating and patient pain. RESULTS Acoustic simulations show that the maximum distance to produce continuous necrosis between foci in a multiple focus pattern and in a temporally multiplexed pattern is approximately 50% larger than the distance needed between sequential foci. CONCLUSION Multiple focus patterns or rapidly scanned single foci are significantly advantageous to sequential sonications of a single focus transducer.

BACKGROUND: We analyzed the causes and results of utilization of critical care services in the special care unit in patients after surgical procedures performed by the hepatobiliary surgical service during a 23-month period. RESULTS: Thirty-two of 537 patients (6.0%) required postoperative admission to the special care unit. Twenty-one patients were admitted directly from operating room or from recovery room because of inability to wean from ventilator (n = 10), hypovolemic shock (n = 4), myocardial ischemia or infarction (n = 2), sepsis (n = 2), upper gastrointestinal bleeding (n = 2), and acute renal failure (n =1). Eleven postoperative patients were admitted from floor care for respiratory failure (n = 4), cardiac dysrhythmia or infarction (n = 4), sepsis (n = 2), and upper gastrointestinal bleeding (n = 1). Thirty-eight per cent of patients (n = 12) admitted to the special care unit after surgery died. By multivariate analysis, total postoperative stay in the special care unit that was greater than median total duration of stay of 4.5 days was the only independent predictor of mortality (P = 0.041). CONCLUSIONS: Respiratory failure was the predominant component of all complications after hepatobiliary surgery. No clinically useful predictors of eventual outcome could be identified.

Abstract
BACKGROUND Most reports highlighting decreasing operative morbidity and mortality rates following hepatic resection have focused on the management of metastatic disease. Information on the full range of hepatic disease is lacking. METHODS The indications for hepatic resection in a specialist hepatobiliary unit have been reviewed and the operative morbidity and mortality rates assessed. RESULTS Among 129 patients undergoing 133 hepatic resections between October 1988 and September 1996, the principal indication for resection was hepatic malignancy (102 resections), metastatic in 66 cases. Other indications included contiguous tumour (n = 20), primary tumour (n = 16) and benign disease (n = 31). Some 116 procedures were classical anatomical resections. Blood transfusion was required in 40 per cent of cases but major morbidity occurred in 20 per cent. There were six deaths following surgery, five of which were due to hepatic failure and followed resection for malignancy or trauma. The 3-year survival rate in patients resected for colorectal metastases was 65 per cent. CONCLUSION This experience has demonstrated an increasing role for hepatic resection in a wide variety of hepatobiliary pathologies. Despite the low postoperative mortality rate, the significant risk of complications in the postoperative period serves to emphasize the need for careful selection of patients for such surgery, which should be undertaken in specialist centres.
