Abstract
OBJECTIVE Glucocorticoids have been used in patients undergoing perioperative hepatectomy, however their safety and efficacy remain controversial. This meta-analysis was conducted to investigate this issue and further provide reference for clinical practice. METHODS PubMed/MEDLINE, Embase, and Cochrane Library were searched for randomized controlled trials (RCTs) from database inception to December 2022. Literature screening and data extraction were performed independently by two reviewers. The methodological quality of the RCTs was assessed using the Jadad scale. RevMan 5.4 was used for the meta-analysis. RESULTS A total of 11 RCTs involving 905 patients were included. Compared with the control group, we found perioperative glucocorticoid administration significantly lowered overall complication rate [RR = 0.67; 95% CI (0.55, 0.83); P = 0.0003], infectious complication rate [RR = 0.41; 95% CI (0.21, 0.82); P = 0.01] and postoperative liver failure [RR = 0.63; 95% CI (0.41, 0.97); P = 0.03]. In addition, glucocorticoids appear to improve liver function (TBil) [MD = -0.36, 95% CI (-0.59, -0.14), P = 0.001] and reduce the release of certain inflammatory cytokines (IL-6) [MD = -48.52, 95% CI (-56.88, -40.16), P < 0.00001]. CONCLUSION Based on the available evidence, glucocorticoids appear to be safe and effective in patients undergoing hepatectomy, but further research is needed.

Post-hepatectomy venous thromboembolism: a systematic review with meta-analysis exploring the role of pharmacological thromboprophylaxis. Langenbecks Arch Surg 2022; 407:3221-3233. [PMID: 35881311 DOI: 10.1007/s00423-022-02610-9] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2022] [Accepted: 07/12/2022] [Indexed: 10/16/2022]
Abstract
PURPOSE Patients undergoing hepatectomy are at moderate-to-high risk of venous thromboembolism (VTE). This study critically examines the efficacy of combining pharmacological (PTP) and mechanical thromboprophylaxis (MTP) versus only MTP in reducing VTE events against the risk of hemorrhagic complications. METHODS A systematic review of major reference databases was undertaken, and a meta-analysis was performed using common-effects model. Risk of bias assessment was performed using Newcastle-Ottawa scale. Trial sequential analysis (TSA) was used to assess the precision and conclusiveness of the results. RESULTS 8 studies (n = 4238 patients) meeting inclusion criteria were included in the analysis. Use of PTP + MTP was found to be associated with significantly lower VTE rates compared to only MTP (2.5% vs 5.3%; pooled RR 0.50, p = 0.03, I2 = 46%) with minimal type I error. PTP + MTP was not associated with an increased risk of hemorrhagic complications (3.04% vs 1.9%; pooled RR 1.54, p = 0.11, I2 = 0%) and had no significant impact on post-operative length of stay (12.1 vs 10.8 days; pooled MD - 0.66, p = 0.98, I2 = 0%) and mortality (2.9% vs 3.7%; pooled RR 0.73, p = 0.33, I2 = 0%). CONCLUSION Despite differences in the baseline patient characteristics, extent of hepatectomy, PTP regimens, and heterogeneity in the pooled analysis, the current study supports the use of PTP in post-hepatectomy patients (grade of recommendation: strong) as the combination of PTP + MTP is associated with a significantly lower incidence of VTE (level of evidence, moderate), without an increased risk of post-hepatectomy hemorrhage (level of evidence, low).

Abstract
Backgrounds/Aims The aim of this study was to describe clinical and biological changes in a group of patients who underwent pancreaticoduodenectomy (PD) without any complication during the postoperative period. These changes reflect the "natural history" of PD, and a deviation should be considered as a warning sign. Methods Between January 2000 and December 2009, 131 patients underwent PD. We prospectively collected and retrospectively analyzed demographic data, pathological variables, associated pathological conditions, and preoperative, intraoperative, and postoperative variables. Postoperative variables were validated using an external prospective database of 158 patients. Results The mean postoperative length of hospital stay was 20.3±4 days. The mean number of days until removal of nasogastric tube was 6.3±1.6 days. The maximal fall in hemoglobin level occurred on day 3 and began to increase after postoperative day (POD) 5, in patients with or without transfusions. The white blood cell count increased on POD 1 and persisted until POD 7. There was a marked rise in aminotransferase levels at POD 3. The peak was significantly higher in patients with hepatic pedicle occlusion (866±236 IU/L versus 146±48 IU/L; p<0.001). For both γ-glutamyl transpeptidase and alkaline phosphatase, there was a fall on POD1, which persisted until POD 5, followed with a stabilization. Bilirubin decreased progressively from POD 1 onwards. Conclusions This study facilitates a standardized biological and clinical pathway of follow-up. Patients who do not follow this recovery indicator could be at risk of complications and additional exams should be made to prevent consequences of such complications.

Abstract
Background: Coagulopathy after living donor hepatectomy (LDH) may endanger donor safety during removal of thoracic epidural catheter (TEC). The present study was conducted to evaluate the extent and duration of immediate postoperative coagulopathy after LDH. Materials and Methods: A retrospective analysis of perioperative record of LDH over three years was conducted after IRB approval. Variables such as age, gender, BMI, ASA classification, liver volume on CT scan, preoperative and postoperative INR, platelet count (PC) and ALT of each donor for five days was noted. In addition, duration of surgery, remnant as percentage total liver volume (Remnant%), blood loss, day of peak in PC and INR were also noted. Coagulopathy was defined as being present if INR exceeded 1.5 or platelet count fell below 1 × 105/mm3 on any day. Data was analyzed using SPSS 20 for Windows. Between group comparison was made using the Student ‘t’ test for continuous variables and chi square test for categorical variables. Univariate analysis was done. Multiple logistic regression analysis was used to find independent factor associated with coagulopathy. Results: Eighty four (84) donors had coagulopathy on second day (mean INR 1.9 ± 0.42). Low BMI, % of remnant liver and duration of surgery were independent predictors of coagulopathy. Right lobe hepatectomy had more coagulopathy than left lobe and low BMI was the only independent predictor. There was no correlation of coagulopathy with age, gender, blood loss, presence of epidural catheter, postoperative ALT or duration of hospital stay. High INR was the main contributor for coagulopathy. Conclusions: Coagulopathy is seen after donor hepatectomy. We recommend removal of the epidural catheter after the fifth postoperative day when INR falls below 1.5.

Abstract
TRIAL DESIGN A prospective randomised controlled trial was designed to evaluate the advantages of routine application of the anterior approach during right hepatectomy. METHODS The study was conducted between March 2005 and April 2009 in a tertiary hepatobiliary-pancreatic centre. Patients scheduled for right hepatectomy for primary or metastatic tumours, without infiltration of segment 1, inferior vena cava or main bile duct, were randomly assigned to right hepatectomy using either an anterior or a classic approach. The primary study endpoint was overall blood loss. RESULTS Sixty-six patients were randomly allocated to undergo right hepatectomy with an anterior (AA group n=33) or a classic approach (CA group n=33). Sixty-five patients were included in the analysis (33 in AA group and 32 in CA group). There was no significant difference in patient age, diagnosis, preoperative hepatic biochemistry and tumour size between the two groups. Overall blood loss (437 ml ± 664 in AA group vs.500 ml ± 532.3 in CA group; p=0.960) and bleeding during transection (p=0.973) were similar between two groups. Perioperative blood transfusion rates were 18% in the AA group and 9.3 % in the CA group (p=0.253). Time of parenchymal transsection was significantly longer in AA group (75.1 ± 26.6 min vs. 56.7 ± 17.5 min, p=0.01). There was no difference between both groups for postoperative prothrombin time, serum transaminase and total bilirubin levels. One patient died in each group (p=0.746). The two groups had similar morbidity rates. CONCLUSION Routine application of the anterior approach during right hepatectomy does not decrease intraoperative blood loss and morbidity rate.

Abstract
BACKGROUND Variations in the definition of bile leakage after hepatic resection have prevented the identification of risk factors for early diagnosis and efficient management. The International Study Group of Liver Surgery (ISGLS) definition standardizes reporting of this complication. It was our aim in the present study to prospectively validate the ISGLS definition of bile leakage after hepatic resection. Furthermore, we sought to identify early predictors of clinically relevant bile leakage. METHODS A total of 265 patients who underwent elective hepatic resection were enrolled prospectively. Bilirubin concentrations were determined in the serum and drainage fluid until postoperative day 5. Risk factors of Grade B/C bile leakage were assessed by the use of univariate and multivariate analyses. RESULTS Grade A, B, and C bile leakage was diagnosed in 23 (8.7%), 38 (14.3%), and 11 (4.1%) patients, respectively. The definition as well as severity grading of bile leakage correlated with the duration of drainage and intensive care unit and hospital stay. Perioperative mortality was 0% for Grade A, 5.2% for Grade B, and 45.4% for Grade C bile leakage (P < .0001). Multivariate analysis confirmed bilirubin concentration in the drainage fluid ≥2.4 mg/dL on postoperative day 2 (odds ratio 11.88; 95% confidence interval 5.33-26.49; P < .0001) and anatomic resection (odds ratio 3.59; 95% CI 1.08-11.97; P = .04) as independent predictors of clinically relevant bile leakage. CONCLUSION The ISGLS definition and severity grading of bile leakage after hepatic resection is clinically meaningful. Bilirubin concentration in the drainage fluid on postoperative day 2 is a strong predictor of clinically relevant bile leakage.

Abstract
STUDY OBJECTIVE To evaluate the effect of chronic hepatic disease on postoperative coagulation. DESIGN Retrospective cohort study. SETTING Operating room with postoperative inpatient followup. MEASUREMENTS The records of 153 patients who underwent elective open hepatic resection were reviewed. The perioperative coagulation profile of each patient was assessed. The postoperative period was subdivided into the early [postoperative day (POD) 0-3] and late (POD 4 - POD 7) periods. MAIN RESULTS 68 (44.4%) patients had chronic hepatic disease and 50 (32.7%) had cirrhosis. Eighty-four (54.9%) patients had an abnormal early postoperative coagulation profile and 46 (30.1%) had an abnormal late postoperative coagulation profile. The proportion of patients having an abnormal coagulation profile peaked on POD 2, at 39.2%. Only 5.3% of patients had an abnormal coagulation profile on POD 7. The independent predictors of abnormal early and late postoperative coagulation profiles were preexisting hepatic cirrhosis [early: odds ratio (OR) 3.73(1.49 - 9.29), late: OR 6.84(2.11 - 22.21)], abnormal preoperative coagulation profile [early: OR 9.68 (1.97 - 47.5), late: OR 11.71 (3.61- 38.02)], major hepatic resection [early: OR 4.15 (1.66 - 10.4), late: OR 5.43 (1.68 - 17.47)], and intraoperative blood loss. CONCLUSIONS An abnormal postoperative coagulation profile after hepatic surgery is common in a patient population with chronic hepatic disease.

Abstract
OBJECTIVE The aim of this study was to identify "inherent limitations" in healthy donors who are responsible for donor morbidity after right hepatectomy (RH) for adult-to-adult living donor liver transplantation (ALDLT). BACKGROUND Right hepatectomy for ALDLT remains a challenging procedure without significant improvement in morbidity over time. This suggests some "inherent limitations" in healthy individuals, which are beyond the recent improvements in the donor evaluation and selection process and refinements in surgical technique during the learning curve. METHODS To identify response of RH in ALDLT, we prospectively studied 32 patients requiring an RH for benign liver lesions (BL), matched with 32 living donors (LD) operated by same team. All patients underwent liver volume evaluation by computed tomographic (CT) volumetry preoperatively and 1 week after RH, postoperative complications graded with Clavien's system. RESULTS The comparison (LD vs BL) showed that remnant liver volume (RLV) on preoperative CT volumetry was higher in the BL group (450 ± 150 vs 646 ± 200 mL, P < 0.001) representing 31% ± 7% in LD group versus 36% ± 7% of the total liver volume in BL group (P = 0.03). On postoperative day 7, the RLV was similar in the 2 groups (866 ± 162 vs 941 ± 153 mL) resulting from a significantly higher regeneration rate in the LD group (89% vs 55%, P = 0.009). Overall complications rate was lower in the BL group (46% vs 21%, P = 0.035). CONCLUSIONS Right hepatectomy in LDLT induces a more severe deprivation of liver volume than in BL, which induce an accelerated regeneration. Accelerated regeneration could represent "inherent limitation" in healthy donors that makes them more vulnerable for postoperative complications.

Abstract
The aim of this study was to evaluate the role for additional testing of coagulation in perioperative management of patients undergoing major hepatic resection. Major outcome measures were perioperative measurements of hemostatic factors (activated partial prothrombin time [aPTT], prothrombin time/international normalized ratio, fibrinogen, antithrombin-III). We conducted a prospective, single-blind study comparing hemostatic factors in patients undergoing major hepatectomy, Whipple procedures, and other gastrointestinal operations. Ninety-five consecutive patients were enrolled. No values differed significantly at baseline. Immediately postoperative, only international normalized ratio was significantly lower comparing major hepatectomy with Whipple ( P < 0.005) and other procedures ( P < 0.0032). Twenty-four hours postoperative, antithrombin-III was lower for major hepatectomy than Whipple ( P < 0.028) and others ( P < 0.0001); fibrinogen was lower compared with Whipple ( P < 0.014) and others ( P < 0.0009); international normalized ratio was lower to compared with Whipple ( P < 0.0001) and others ( P < 0.0001). aPTT measurements never differed significantly between groups at any time. Antithrombin-III and fibrinogen only correlated with international normalized ratio and aPTT for the other procedures. Additional hemostatic values beyond the standard evaluations of aPTT and international normalized ratio are needed to better assess patients undergoing major hepatic surgery.

Abstract
BACKGROUND A standardized definition of post-hepatectomy haemorrhage (PHH) has not yet been established. METHODS An international study group of hepatobiliary surgeons from high-volume centres was convened and a definition of PHH was developed together with a grading of severity considering the impact on patients' clinical management. RESULTS The definition of PHH varies strongly within the hepatic surgery literature. PHH is defined as a drop in haemoglobin level > 3 g/dl post-operatively compared with the post-operative baseline level and/or any post-operative transfusion of packed red blood cells (PRBC) for a falling haemoglobin and/or the need for radiological intervention (such as embolization) and/or re-laparotomy to stop bleeding. Evidence of intra-abdominal bleeding should be obtained by imaging or blood loss via the abdominal drains if present. Transfusion of up to two units of PRBC is considered as being Grade A PHH. Grade B PHH requires transfusion of more than two units of PRBC, whereas the need for invasive re-intervention such as embolization and/ or re-laparotomy defines Grade C PHH. CONCLUSION The proposed definition and grading of severity of PHH enables valid comparisons of results from different studies. It is easily applicable in clinical routine and should be applied in future trials to standardize reporting of complications.

Abstract
The importance of partial liver resection as a therapeutic option to cure hepatic tumors has increased over the last decades. This has been influenced on the one hand by advances in surgical and anesthetic management resulting in a reduced mortality after surgery and on the other hand by an increased incidence of hepatocellular carcinoma. Nowadays, partial resection of the liver is performed safely and as a routine operation in specialized centers. This article describes the pathophysiological changes secondary to liver failure and assesses the perioperative management of patients undergoing partial or extended liver resection. It looks in detail at the preoperative assessment, the intraoperative anesthetic management including fluid management and techniques to reduce blood loss as well as postoperative analgesia and intensive care therapy.

Abstract
BACKGROUND Hepatic resection continues to be associated with substantial morbidity. Although biochemical tests are important for the early diagnosis of complications, there is limited information on their postoperative changes in relation to outcome in patients with surgery-related morbidity. METHODS A total of 835 consecutive patients underwent hepatic resection between January 2002 and January 2008. Biochemical blood tests were assessed before, and 1, 3, 5 and 7 days after surgery. Analyses were stratified according to the extent of resection (3 or fewer versus more than 3 segments). RESULTS A total of 451 patients (54·0 per cent) underwent resection of three or fewer anatomical segments; resection of more than three segments was performed in 384 (46·0 per cent). Surgery-related morbidity was documented in 258 patients (30·9 per cent) and occurred more frequently in patients who had a major resection (P = 0·001). Serum bilirubin and international normalized ratio as measures of serial hepatic function differed significantly depending on the extent of resection. Furthermore, they were significantly affected in patients with complications, irrespective of the extent of resection. The extent of resection had, however, little impact on renal function and haemoglobin levels. Surgery-related morbidity caused an increase in C-reactive protein levels only after a minor resection. CONCLUSION Biochemical data may help to recognize surgery-related complications early during the postoperative course, and serve as the basis for the definition of complications after hepatic resection.

Abstract
BACKGROUND Hepatic resection may be associated with postoperative coagulopathy. However, there is limited information about the predictors affecting coagulopathy after donor hepatectomy. We evaluated the contributors of maximal changes in prothrombin time (PT), activated thromboplastin time (aPTT), and platelet count in the development of postoperative coagulopathy. METHODS We retrospectively analyzed 864 living donors, all of whom received general anesthesia using desflurane, isoflurane, or sevoflurane. A coagulation derangement was defined as one or more of the following events postoperatively: peak PT >1.5 international normalized ratio (INR; highest quartile of PT), peak aPTT >46 seconds (highest quartile of aPTT), or nadir platelet count <100 × 10(9)/L. Factors were evaluated by univariate and multivariate logistic regression analysis to identify predictors of coagulopathy. RESULTS Mean postoperative peak PT, peak aPTT, and nadir platelet count were 1.4 ± 0.2 INR, 43.8 ± 23.7 seconds, and 155.9 ± 37.3 × 10(9)/L, respectively, with 39.4% of donors being at the risk for coagulation derangement. Multivariate logistic regression analysis revealed that predictors of such derangement included anesthesia duration, remnant liver volume, and body mass index (BMI). However, coagulation derangement was not independently associated with age, gender, volatile anesthetics, central venous pressure, fatty change in the liver, estimated blood loss, or intraoperative hypotensive episodes. CONCLUSION We found that long anesthesia duration, low BMI, and small remnant liver volume were predictors of coagulation derangement. These results provide a better understanding of risk factors affecting changes in coagulation profiles after living donor hepatectomy.

Abstract
SUMMARY We performed a prospective randomised trial to evaluate the analgesic efficacy of interpleural analgesia in patients undergoing hepatic resection. The control group (n = 25) received multimodal analgesia with intravenous morphine patient-controlled analgesia; in addition, the interventional group (n = 25) received interpleural analgesia with a 20-ml loading dose of levo bupivacaine 0.5% followed by a continuous infusion of levobupivacaine 0.125%. Outcome measures included pain intensity on movement using a visual analogue scale over 24 h, cumulative morphine and rescue analgesia requirements, patient satisfaction, hospital stay and all adverse events. Patients in the interpleural group were less sedated and none required treatment for respiratory depression compared to 6 (24%) in the control group (p< 0.01). Patients in the interpleural group also had lower pain scores during movement in the first 24 h. Patients' satisfaction, opioid requirements and duration of hospital stay were similar. We conclude that continuous interpleural analgesia augments intravenous morphine analgesia, decreases postoperative sedation and reduces respiratory depression after hepatic resection.

Abstract
AIMS To analyse the effects of the preoperative targeted molecular therapy (cetuximab (cetu) or bevacizumab (beva)) on non-tumorous liver parenchyma, and the clinical and biological outcome after liver resection for colorectal liver metastases (CLM). METHODS Between January 2005 and December 2007, 36 patients receiving preoperatively cetu (n = 15) or beva (n = 21) were, respectively, matched to a control group of patients who did not receive targeted molecular therapy. They were matched on the basis of age, gender, body mass index, extent of hepatectomy, and type and number of neoadjuvant chemotherapy. Liver function tests, postoperative outcome and histopathology of the resected liver were compared. RESULTS There was no mortality. Postoperative morbidity and perioperative bleeding rates were similar in both groups. In the beva group, liver function tests showed higher serum bilirubin level on postoperative day (POD) 1 (p = 0.001) and POD 3 (p = 0.01), higher serum aspartate aminotransferase on POD 1 (p = 0.004), and lower prothrombin time on POD 5 (p = 0.02). In both groups, cetu and beva, the postoperative peaks of gamma-glutamyl transpeptidase and alkaline phosphatase were statistically higher than in the control groups. Interestingly, the prevalence of sinusoidal injury and fibrosis was lower in patients receiving cetu (p = 0.04), while the prevalence of steatohepatitis was lower in patients receiving beva (p = 0.04). CONCLUSION The addition of beva or cetu to the neoadjuvant chemotherapy regimens does not appear to increase the morbidity rates after hepatectomy for CLM. The pathological examination did not show additional injury to the non-tumorous liver parenchyma.

Abstract
AIM: To characterize the impact of the Pringle maneuver (PM) and ischemic preconditioning (IP) on total blood supply to the liver following hepatectomies.
METHODS: Sixty one consecutive patients who underwent hepatic resection under inflow occlusion were randomized either to receive PM alone (n = 31) or IP (10 min of ischemia followed by 10 min of reperfusion) prior to PM (n = 30). Quantification of liver perfusion was measured by Doppler probes at the hepatic artery and portal vein at various time points after reperfusion of remnant livers.
RESULTS: Occlusion times of 33 ± 12 min (mean ± SD) and 34 ± 14 min and the extent of resected liver tissue (2.7 segments) were similar in both groups. In controls (PM), on reperfusion of liver remnants for 15 min, portal perfusion markedly decreased by 29% while there was a slight increase of 8% in the arterial blood flow. In contrast, following IP + PM the portal vein flow remained unchanged during reperfusion and a significantly increased arterial blood flow (+56% vs baseline) was observed. In accordance with a better postischemic blood supply of the liver, hepatocellular injury, as measured by alanine aminotransferase (ALT) levels on day 1 was considerably lower in group B compared to group A (247 ± 210 U/I vs 550 ± 650 U/I, P < 0.05). Additionally, ALT levels were significantly correlated to the hepatic artery inflow.
CONCLUSION: IP prevents postischemic flow reduction of the portal vein and simultaneously increases arterial perfusion, suggesting that improved hepatic macrocirculation is a protective mechanism following hepatectomy.

Abstract
BACKGROUND The aim of this study was to provide an improved outline of the patterns and correlates of changes in plasma bilirubin after partial hepatectomy. METHODS A large series of blood measurements and complementary variables were prospectively collected from 85 patients undergoing liver resection, and bilirubin correlations were assessed by regression analysis. RESULTS Early postoperatively, the best simultaneous correlates of increasing bilirubin were the preoperative value, the duration of surgery, and the number of blood transfusions (r2 = 0.74, p < 0.001). Subsequently, increasing bilirubin became related to the number of resected liver segments, the duration of intraoperative liver ischemia, the use of continuous vs. intermittent ischemia, and the presence of sepsis (r2 = 0.82, p < 0.001); these were also the best simultaneous correlates of peak bilirubin. This pattern was characterized by prominently conjugated hyperbilirubinemia, hypocholesterolemia, and moderately increased alkaline phosphatase, and occurred in the absence of obstructive cholestasis. CONCLUSIONS Major hepatectomy, parenchymal ischemia, and sepsis have similar and synergistic impacts as determinants of prominently conjugated hyperbilirubinemia after liver resection. This is likely related to impaired hepatocellular bilirubin transport and occurs in the absence of obstructive components.

Abstract
BACKGROUND Postoperative hepatic insufficiency is a critical complication after extended hepatic resection in patients with biliary tract malignancies, the majority of whom suffer from obstructive jaundice. The aim of this study was to assess clinical parameters linked to this type of liver dysfunction. METHODS A total of 111 patients were retrospectively reviewed. Patient background, pre- and intraoperative parameters, and a ratio of remnant liver volume/entire liver volume (RLV/ELV) as a volumetric parameter were compared between patients with and without postoperative hyperbilirubinemia and subsequent fatal outcome. RESULTS Logistic regression indicated that only RLV/ELV ratio was an independent factor influencing postoperative hyperbilirubinemia, and RLV/ELV ratio and indocyanine green retention rate at 15 minutes (ICG-R15) were factors affecting survival. Patients with RLV/ELV less than 40% had 7.6 times the risk of postoperative hyperbilirubinemia, while no patients with RLV/ELV greater than 40% and ICG-R15 less than 25% died of liver failure. CONCLUSIONS The RLV/ELV ratio was the factor with the greatest impact on liver dysfunction after extended hepatectomy in patients with biliary tract malignancies.

Abstract
Liver failure is a dreaded and often fatal complication that sometimes follows a partial hepatic resection. This article reviews the definition, incidence, pathogenesis, risk factors, risk assessment, prevention, clinical features and treatment of post-resectional liver failure (PLF). A systematic, computerized search was performed using key words related to 'partial hepatic resection' and 'liver failure' to review most relevant literature about PLF published in the last 20 years. The reported incidence of PLF ranges between 0.7 and 9.1%. An inadequate quantity or quality of residual liver mass are key events in its pathogenesis. Major risk factors are the presence of comorbid conditions, pre-existent liver disease and small remnant liver volume (RLV). It is essential to identify these risk factors during the pre-operative assessment that includes evaluation of liver volume, anatomy and function. Preventive measures should be applied whenever possible as curative treatment options for PLF are limited. These preventive measures intend to increase RLV and protect remnant liver function. Management principles focus on support of end-organ and liver function. Further research is needed to elucidate the exact pathogenesis of PLF and to develop and validate adequate treatment options.

Abstract
BACKGROUND The future remnant liver (FRL) limit for safe major hepatectomy with low risk of postoperative liver failure has not yet been well defined. METHODS Between April 2000 and September 2004, every patient scheduled for major hepatectomy in our institution underwent CT-volumetry of FRL. Patients with FRL <25% underwent portal vein embolization (PVE). Exclusion criteria were PVE, associated vascular resection and liver cirrhosis. The FRL was correlated with short-term results in patients with normal liver (group A) and those with impaired liver function secondary to neoadjuvant chemotherapy or cholestasis (bilirubin >2 mg/100 ml) (group B). Liver dysfunction was defined as both PT <50% and serum bilirubin level >5 mg/100 ml for three or more consecutive days. RESULTS A total of 119 patients were analyzed, 72 in group A and 47 in group B. The FRL value was the only significant risk factor for postoperative liver dysfunction in the univariate and multivariate analysis (p = 0.009). The FRL did not correlate with postoperative mortality and morbidity. Bilirubin and prothrombin time (PT) on days 3 and 7 were significantly correlated to FRL in both groups. In group A, patients with postoperative liver dysfunction had a FRL<30% (3 versus 0; p = 0.005). According to receiving operator characteristic (ROC) curve analysis, a FRL value of 26.5% predicted postoperative liver dysfunction with 66.7% sensitivity, 97.1% specificity, 50% positive predictive value (PPV), and 98.5% negative predictive value (NPV). In group B, patients with postoperative liver dysfunction had a FRL <35% (4 versus 0; p = 0.027). According to ROC curve analysis, a FRL value of 31.05% predicted postoperative liver dysfunction with 75% sensitivity, 79.1% specificity, 25% PPV, and 97.1% NPV. CONCLUSIONS Hepatectomy can be considered safe when FRL is >26.5% in patients with healthy liver and >31% in patients with impaired liver function.

Abstract
BACKGROUND Prolonged systemic preoperative chemotherapy induces pathologic changes in liver parenchyma. The consequences of vascular occlusion on liver submitted to prolonged preoperative systemic chemotherapy are not known. The aim of this case-matched study was to assess which method of vascular occlusion is most appropriate for major liver resection in patients who have undergone prolonged preoperative systemic chemotherapy. METHODS Among 305 patients who had liver resection for colorectal metastases from 1998 to 2003, 28 underwent major liver resections under portal triad clamping after more than 6 cycles of preoperative chemotherapy (TC group). These 28 patients were compared with 32 patients matched for age, sex, ASA status, number of liver metastases, type of liver resection, and type of preoperative chemotherapy, but who had major liver resection under hepatic vascular exclusion after more than 6 cycles of preoperative chemotherapy (VE group). RESULTS There was no postoperative mortality. The morbidity rate was 18% after TC and 43% after VE (P = 0.044). Pulmonary complication rate was greater after VE (31% vs 3%, P = 0.017). The transfusion rate was 50% in the TC group and 40% in the VE group (P = 0.482). Postoperative changes of liver function tests were comparable in the two groups except for the prothrombin time, which was more prolonged from day 1 (P = 0.003) to day 5 (P = 0.04) after VE. CONCLUSION Vascular occlusion can be used with no mortality and acceptable morbidity for major liver resection after prolonged preoperative chemotherapy. TC should be preferred to VE, permitted by the location of the neoplasm.

Abstract
INTRODUCTION Paracetamol is often used as an analgesic following hepatic resection. During liver resection, vascular clamping is carried out to reduce blood loss. Previous studies have described transient postoperative rises in serum aminotransferase levels and decreases in prothrombin time and factor V levels. We have examined paracetamol metabolism after liver resection. METHODS A prospective observational study was performed. All patients undergoing liver resection were included. Propacetamol was given every 6 h. Blood samples for plasma paracetamol concentrations were collected before, 1 h after the end of the first injection (T1), just before the second injection (6 h: T6), and just before the fifth injection (24 h: T24). RESULTS 37 patients were recruited. 13 had hepatic vascular exclusion (HVE group), 13 had portal triad clamping (PTC group) and 11 had abdominal surgery with no liver resection (NLR group: control group). At T6, the plasma paracetamol concentration in the HVE group was significantly higher than in the NLR groups; at T24, this concentration was significantly higher in the HVE group than in the NLR and PTC groups, and was higher in the PTC group than in the NLR group. Prothrombin time and factor V was significantly lower in the HVE group than in the PTC group on the first postoperative day. DISCUSSION This study showed a reduction of paracetamol metabolism in the liver resection group with significantly increased paracetamol levels. However, the maximum mean plasma concentration reached was not clinically or toxicologically significant. For these reasons, we cannot suggest that paracetamol should or should not be avoided in patients undergoing liver resection.

BACKGROUND We investigated perioperative complications of hepatic arterial infusion chemotherapy preceding major hepatectomy for multiple bilobar colorectal cancer metastases. No consensus exists concerning operative feasibility or perioperative course in patients undergoing major liver resection with neoadjuvant chemotherapy--partly because such chemotherapy is considered hepatotoxic, increasing the risk of postoperative liver failure. METHODS Clinicopathologic data were available for 41 consecutive patients with 5 or more bilobar liver metastases from colorectal cancer who underwent major liver resection with or without prior hepatic arterial chemotherapy. Data concerning operative feasibility, postoperative liver function, complication rates, and histologic findings in the non-neoplastic liver were analyzed retrospectively. RESULTS Prehepatectomy and postoperative day 1 platelet counts were lower (P < .01 and P < .05), alkaline phosphatase on postoperative day 3 was higher (P < .01), and prothrombin time on day 1 was more prolonged (P < .01) in the chemotherapy group. No significant difference was seen between groups in intraoperative data, morbidity, or duration of hospitalization. Histologic examination of adjacent non-neoplastic liver confirmed mild to severe fatty degeneration in 91% of the patients undergoing neoadjuvant chemotherapy, compared with 53% in those without neoadjuvant chemotherapy (P = .023). Although the number of neoplasms in chemotherapy patients was greater than that of the other group, overall and disease-free survival rates were comparable between groups. CONCLUSIONS Despite mild postoperative liver dysfunction, pre-resection hepatic arterial chemotherapy did not increase morbidity.

Abstract
The extent of donor hepatectomy may affect splenic hypertrophy and platelet count. The subjects were 50 live liver donors. The ratio of the graft weight to total liver volume (GW/TLV) and the splenic hypertrophy ratio, expressed as the splenic volume one month after surgery divided by that before surgery, were calculated. The platelet count one month after surgery was divided by that before surgery to determine the rate of the platelet count decrease. The correlation of GW/TLV to the splenic hypertrophy ratio and the rate of the platelet count decrease were examined. The median (range) GW/TLV was 54 (28-71)%. The splenic hypertrophy ratio and the rate of the platelet count decrease was 133 (99-191)% and 92 (71-129)%, respectively. GW/TLV positively correlated with the splenic hypertrophy ratio (Spearman's correlation coefficient (r(s)) = 0.448, p = 0.001), and negatively correlated with the rate of the platelet count decrease (r(s) = -0.471, p < 0.001). Multivariate analysis revealed that GW/TLV influenced the splenic hypertrophy ratio [adjusted odds ratio (OR), 12.0; 95% confidence interval (CI), 1.32-9.04; p = 0.01] and the ratio of the platelet count decrease (adjusted OR, 11.6; 95% CI, 1.40-8.33; p = 0.01). Larger graft procurement might place living liver donors at higher risk for post-operative thrombocytopenia.

Abstract
OBJECTIVE : To assess the effects of preoperative systemic chemotherapy on remnant liver parenchyma, liver function, and morbidity after major liver resection for colorectal liver metastases. BACKGROUND : Many patients operated upon for colorectal cancer liver metastases receive previous chemotherapy. Whether systemic chemotherapy alters liver parenchyma in such way that it increases the risks of liver resection remains unclear. PATIENTS AND METHODS : Among 214 patients who received a liver resection for colorectal liver metastases between 1998 and 2002 in a single institution, 67 who underwent a major liver resection under total hepatic vascular exclusion form the basis of this report. Forty-five patients operated upon after systemic chemotherapy were compared with 22 who did not receive any chemotherapy in the 6 months prior to resection. Postoperative mortality, morbidity, liver function tests, and pathology of the resected liver in the two groups were compared. RESULTS : There was no postoperative mortality. Values of liver function tests on days 1, 3, 5, and 10 were similar in both groups. Morbidity rate was higher in the chemotherapy group (38% versus 13.5%, P = 0.03). Postoperative morbidity was correlated with the number of cycles of chemotherapy administered before surgery but not to the type of chemotherapy. Preoperative chemotherapy was significantly associated with sinusoidal dilatation, atrophy of hepatocytes, and/or hepatocytic necrosis (49% versus 25%, P = 0.005). CONCLUSION : Prolonged neoadjuvant systemic chemotherapy alters liver parenchyma and increases morbidity after major resection under total hepatic vascular exclusion, but it does not increase operative mortality. This should be taken into consideration before deciding a major liver resection in patients who have received preoperative chemotherapy.

Abstract
OBJECTIVE To standardize the definition of postoperative liver failure (PLF) for prediction of early mortality after hepatectomy. SUMMARY BACKGROUND DATA The definition of PLF is not standardized, making the comparison of innovations in surgical techniques and the timely use of specific therapeutic interventions complex. METHODS Between 1998 and 2002, 775 elective liver resections, including 69% for malignancies and 60% major resections, were included in a prospective database. The nontumorous liver was abnormal in 43% with steatosis >30% in 14%, noncirrhotic fibrosis in 43%, and cirrhosis in 12%. The impact of prothrombin time (PT) <50% and serum bilirubin (SB) >50 micromol/L on postoperative days (POD) 1, 3, 5, and 7 was analyzed. RESULTS The lowest PT level was observed on postoperative day (POD) 1, while the peak of SB was observed on POD 3. These 2 variables tended to return to preoperative values by POD 5. The median interval between hepatectomy and postoperative death was 15 days (range, 5-39 days). Postoperative mortality significantly increased in patients with PT <50% and SB >50 microml/L. The conjunction of PT <50% and SB >50 micromol/L on POD 5 was a strong predictive factor of mortality. In patients with significant morbidity, this "50-50 criteria" was met 3 to 8 days before clinical evidence of complications. CONCLUSIONS The association of PT <50% and SB >50 microml/L on POD 5 (the 50-50 criteria) was a simple, early, and accurate predictor of more than 50% mortality rate after hepatectomy. This criteria could be identified early enough, before clinical evidence of complications, for specific interventions to be applied in due time.

Abstract
The aim of this study is to identify the minimum safe amount of effective remnant liver volume (ERLV) in patients undergoing a major hepatectomy. Thirty-eight consecutive major hepatectomies (resection of ≥3 Couinaud segments) performed between July 1999 and March 2004 in which a frozen section liver biopsy was obtained were included. No patient had chronic viral hepatitis, cirrhosis, or cholestasis. The total liver volume (TLV) was calculated using the Vauthey formula, and the postsurgical liver volume (PSLV) was derived by subtracting the estimated volume of liver resected from the TLV. The PSLV minus the percentage of macrovesicular steatosis as nonfunctional liver was defined as the effective remnant liver volume (ERLV). Three groups of ERLV/TLV ratios (<30%, between 30% and 60%, and >60%) were correlated with liver resection type, mortality, complications, intraoperative blood transfusions, operative time, length of hospitalization, and mean value of liver function tests in the first 5 postoperative days. Comparisons between clinical parameters were performed by Pearson χ2 test. There was significant correlation between ERLV/TLV ratios and surgical resection type ( P < 0.001), early postoperative mortality ( P < 0.01), and complications ( P < 0.003). The ERLV/TLV ratio may be a useful predictor of surgical outcome after major hepatectomy.

Abstract
The risks and benefits of adult-to-adult living donor liver transplantation need to be carefully evaluated. Anesthetic management includes postoperative epidural pain relief; however, even patients with a normal preoperative coagulation profile may suffer transient postoperative coagulation derangement. This study explores the possible causes of postoperative coagulation derangement after donor hepatectomy and the possible implications on epidural analgesia. Thirty donors, American Society of Anesthesiology I, with no history of liver disease were considered suitable for the study. A thoracic epidural catheter was inserted before induction and removed when laboratory values were as follows: prothrombin time (PT) > 60%, activated partial thromboplastin time < 1.24 (sec), and platelet count > 100,000 mmf pound sterling (mm3). Standard blood tests were evaluated before surgery, on admission to the recovery room, and daily until postoperative day (POD) 5. The volumes of blood loss and of intraoperative fluids administered were recorded. Coagulation abnormalities observed immediately after surgery may be related mostly to blood loss and to the diluting effect of the intraoperative infused fluids, although the extent of the resection appears to be the most important factor in the extension of the PT observed from POD 1. In conclusion, significant alterations in PT and platelet values were observed in our patients who underwent uncomplicated major liver resection for living donor liver transplantation. Because the potential benefits of epidural analgesia for liver resection are undefined according to available data, additional prospective randomized studies comparing the effectiveness and safety of intravenous versus epidural analgesia in this patient population should be performed.

Abstract
Haemostatic deficiencies, common among cirrhotic patients, may deteriorate further after hepatectomy, increasing the bleeding risk associated with the use of thoracic epidural analgesia. We describe two patients who enjoyed immediate post-operative tracheal extubation and satisfactory analgesia using mainly right thoracic paravertebral analgesia after right lobe hepatectomy.

Abstract
Living liver donors for adult liver transplant recipients undergo extensive liver resection. Partial donor hepatectomies may alter postoperative drug metabolism and hemostasis; thus, the risks and the benefits of pain management for this unique patient population may need to be reassessed. The safety and efficacy of combined epidural analgesia and field infiltration in our initial living liver donor group are presented. A thoracic epidural catheter was placed before general anesthesia in 2 female and 6 male donors (44.2 +/- 11.3 years old, mean +/- standard deviation [SD], range 26-56). At the end of surgery, incisions were infiltrated (bupivacaine 0.25%), and an epidural infusion was used (bupivacaine 0.1% + hydromorphone hydrochloride 0.02%). Clinical outcomes were followed for 5 days. The time sequence of pain intensity on a 0-10 visual analog scale clustered into 3 phases, the intensity of which differed significantly from each other (2.2 +/- 0.6, 0.69 +/- 0.2, and 2.37 +/- 0.3 respectively, P = 0.028). Right shoulder pain was observed in 75% of the donors. Sedation, pruritus, and nausea were minimal. Consistently maximal international normalized ratio elevation occurred at 17.6 +/- 7 hours postoperatively, then slowly declined. Platelet counts were lowest on day 3. No neurologic injury or local anesthetic toxicity was observed. This 2-site approach provided effective, safe, postoperative analgesia for our donors. Universally, coagulopathy ensued, indicating a potentially increased risk for epidural hemorrhage at epidural catheter removal and mandating close postoperative neurologic and laboratory monitoring. Research is needed to advance the understanding of postoperative coagulopathy and hepatic dysfunction in these donors to further optimize their perioperative management, including that of analgesia.

Abstract
OBJECTIVE To evaluate the potential of postischemic intravenous infusion of the endogenous antioxidant glutathione (GSH) to protect the liver from reperfusion injury following prolonged warm ischemia. BACKGROUND DATA The release of reactive oxygen species (ROS) by activated Kupffer cells (KC) and leukocytes causes reperfusion injury of the liver after warm ischemia. Therefore, safe and cost-effective antioxidant strategies would appear a promising approach to prevent hepatic reperfusion injury during liver resection, but need to be developed. METHODS Livers of male Lewis rats were subjected to 60, 90, or 120 minutes of normothermic ischemia. During a 120 minutes reperfusion period either GSH (50, 100 or 200 micromol/h/kg; n= 6-8) or saline (n= 8) was continuously administered via the jugular vein. RESULTS Postischemic GSH treatment significantly prevented necrotic injury to hepatocytes as indicated by a 50-60% reduction of serum ALT and AST. After 1 hour of ischemia and 2 hours of reperfusion apoptotic hepatocytes were rare (0.50 +/- 0.10%; mean +/- SD) and not different in GSH-treated animals (0.65 +/- 0.20%). GSH (200 micromol GSH/h/kg) improved survival following 2 hours of ischemia (6 of 9 versus 3 of 9 rats; P < 0.05). Intravital fluorescence microscopy revealed a nearly complete restoration of sinusoidal blood flow. This was paralleled by a reduction of leukocyte adherence to sinusoids and postsinusoidal venules. Intravenous GSH administration resulted in a 10- to 40-fold increase of plasma GSH levels, whereas intracellular GSH contents were unaffected. Plasma concentrations of oxidized glutathione (GSSG) increased up to 5-fold in GSH-treated animals suggesting counteraction of the vascular oxidant stress produced by activated KC. CONCLUSIONS Intravenous GSH administration during reperfusion of ischemic livers prevents reperfusion injury in rats. Because GSH is well tolerable also in man, this novel approach could be introduced to human liver surgery.

Abstract
The maximum extent of hepatic resection compatible with a safe postoperative outcome is unknown. The study goal was to determine the incidence and impact of a small remnant liver volume after major liver resection in patients with normal liver parenchyma. Among 265 major hepatectomies performed at our institution (1998 to 2000), 138 patients with normal liver and a remnant liver volume (RLV) systematically calculated from the ratio of RLV to functional liver volume (FLV) were studied. Patients were divided into five groups based on RLV-FLV ratio from </=30% to >/=60%. Kinetics of postoperative liver function tests were correlated with RLV. Postoperative complications were stratified by RLV-FLV ratios. Ninety patients (65%) underwent resection of up to four Couinaud segments. The RLV-FLV ratio was </=60% in 94 patients (68%) including only 13 (9%) with RLV-FLV </=30%. There was no linear correlation between the number of resected segments and the RLV-FLV. Postoperative serum bilirubin but not prothrombin time correlated with extent of resection. The incidence of complications including liver failure was not different among groups. Analysis of the four groups with a RLV-FLV ratio <60% showed a trend toward more complications and a longer intensive care unit stay in patients with the smallest RLVs. After major hepatectomy in patients with normal livers, the proportion of patients with a small remnant liver is low and not directly related to the number of segments resected. Although the rate of postoperative complications, including liver failure, did not directly correlate with the volume of remaining liver, the postoperative course was more difficult for patients with smaller remnants. Therefore preoperative portal vein embolization should be considered in patients who will undergo extended liver resection who have (1) injured liver or (2) normal liver when the planned procedure will be complex or when the anticipated RLV-FLV will be <30%.

Abstract
OBJETIVO: As metástases hepáticas do carcinoma colorretal, constituem-se, atualmente, em doença potencialmente curável, através dos diversos tipos de ressecções hepáticas, entre as quais se sobressai a hepatectomia direita. Os objetivos deste trabalho são analisar a evolução pré, per e pós-operatória de pacientes submetidos a hepatectomia direita por metástases hepáticas do adenocarcinoma colorretal, seu prognóstico e a exeqüibilidade de re-ressecção nos casos de recidiva tumoral hepática. MÉTODO: Cinquenta e sete pacientes submetidos à hepatectomia direita por metástases hepáticas do carcinoma colorretal com intenção curativa, entre 1990 e 2000, no Hospital Beaujon, Clichy-França, foram analisados retrospectivamente. O período de seguimento pós-operatório foi de 33±25 meses. RESULTADOS: Não houve mortalidade operatória. Em 29,8% dos casos houve necessidade de transfusão e o índice de complicações pós-operatórias foi de 57,9%. Metástases maiores que 5cm foram observadas em 59% dos pacientes e 78,5% apresentavam mais de uma lesão. A sobrevida de cinco anos foi de 43% e a sobrevida livre de doença no mesmo período foi de 23%.Recidiva hepática do tumor foi observada em 19,3% dos pacientes e destes, 45,5% foram submetidos à re-ressecção hepática também sem mortalidade. CONCLUSÕES: A hepatectomia direita é um procedimento seguro para o tratamento das metástases hepáticas do carcinoma colorretal confinadas no lobo direito do fígado, com baixa mortalidade e morbidez aceitável nos pacientes estudados. A sobrevida de cinco anos encontra-se dentro da média observada na literatura. As re-ressecções hepáticas mostraram-se exequíveis em cerca de metade dos casos de recidiva.

Abstract
BACKGROUND There is no agreement regarding the preoperative measurement of liver volumes and the minimal safe size of the liver remnant after extended hepatectomy. METHODS In 20 patients with hepatobiliary malignancy and no underlying chronic liver disease, volumetric measurements of the liver remnant (segments 2 and 3 +/- 1) were obtained before extended right lobectomy (right trisegmentectomy). The ratios of future liver remnant to total liver volume were calculated by using a formula based on body surface area. In 12 patients, response to preoperative right trisectoral portal vein embolization was evaluated. In 15 patients who underwent the planned resection, preoperative volumes were correlated with biochemical and clinical outcome parameters. RESULTS The future liver remnants increased after portal vein embolization (26% versus 36%, P < .01). Smaller size liver remnants were associated with an increase in postoperative liver function tests (P < .05) and longer lengths of hospital stay (P < .02). Preliminary data indicates an increase in major complications for liver volumes < or = 25% (P = .02). CONCLUSIONS A simple method of measurement provides an assessment of the liver remnant before resection. It is useful in evaluating response to portal vein embolization and in predicating the outcome before extended liver resections.

Abstract
OBJECTIVE To report the results of a selective use of vascular occlusions in major hepatectomies according to the size and location of the hepatic lesion. BACKGROUND Total vascular exclusion (TVE) and portal triad clamping (PTC) ensure efficient hemostatic effect but lead to warm ischemia of the liver. Lobar vascular occlusion (LVO) avoids warm ischemia of the remnant liver but could result in increased blood loss. PATIENTS AND METHODS Sixty consecutive major hepatectomies were studied. TVE was applied in 22 patients with large lesions (= 10 cm) or lesions with connections to the major hepatic veins or inferior vena cava. PTC (n = 15) and LVO (n = 23) were applied in remaining cases. RESULTS Clamping method was efficient in 87%, 93% and 100% for LVO, PTC and TVE, respectively. Median blood transfusions were 0.3 and 2 units for LVO, PTC and TVE, respectively. Postoperative aminotransferase peak value was significantly lower after LVO than after PTC or TVE, while those peaks were not statistically different with these latter two methods. Postoperative prothrombin time fall value was identical in the three groups. Mortality was 3.3% (2/60) and was not influenced by the type of clamping, but both deaths and most complications occurred in patients with abnormal underlying liver parenchyma. CONCLUSION Provided that adequate techniques are used, the need for blood transfusions is more dependent on the characteristics of the resected tumor than on the type of clamping used. Total vascular exclusion does not create more ischemic injury to the liver than portal triad clamping and it should be recommended for the resection of large or strategically located tumors. Other tumors can be resected in more than 80% of the cases with LVO, thus avoiding ischemia to the remnant liver. With the control of hemorrhage, pathology of underlying liver parenchyma has emerged as the main prognostic factor in major liver resections.

Abstract
A isquemia transitória hepática tem sido cada vez mais amplamente utilizada. Contudo, essa atitude, embora muitas vezes benéfica, é contrabalançada pelos efeitos adversos advindos da isquemia hepática e da congestão esplênica, assim como, das conseqüências da reperfusão. O objetivo dos autores é determinar os efeitos da isquemia seletiva em animais pré-tratados ou não com alopurinol, inibidor da xantina oxidase sobre a mortalidade dos animais. Foram utilizados 30 ratos assim divididos: Grupo I (n=10): pré-tratados com alopurinol e submetidos à laparotomia e exposição do pedículo hepático por 45 minutos. Grupo II (n=10): tratados com alopurinol e submetidos à isquemia hepática seletiva por 45 minutos. Grupo III (n=10): submetidos apenas à isquemia por 45 minutos. A mortalidade pós-operatória foi avaliada a cada 24 horas, por um período de 10 dias. Entre os animais do grupo I, não foram observados óbitos, entretanto, naqueles dos grupos II e III, as mortalidades globais foram respectivamente 20 e 46,7%. Diferença estatisticamente significativa, apenas, entre a mortalidade observada no grupo III em relação ao controle (p<0,05). A mortalidade pós-operatória no grupo de animais submetidos à isquemia sem pré-tratamento com alopurinol ascende as cifras de 46,67% dos animais, enquanto naqueles pré-tratados com alopurinol houve um importante decréscimo para 20%. Embora sem uma distinção estatisticamente significativa, reflete uma tendência de um efeito protetor do alopurinol na isquemia e reperfusão hepática.

Abstract
Dramatic improvements in morbidity and mortality rates following liver resections have been reported in the past decade. Consequently, the indications for hepatectomy are becoming more liberal. Many techniques of liver resection with or without vascular clamping have been reported with excellent clinical results. Total vascular exclusion (TVE) of the liver during parenchymal transection has been advocated susceptible to increase the resectability of tumors that might not be safely approached by other techniques. Cirrhotic livers are probably more vulnerable to ischemic injury related to TVE than normal livers. The indications and technical and metabolic aspects of the technique are reviewed.

Abstract
BACKGROUND Although hepatic vascular clampings are widely used during major hepatic resections, they may not always be necessary. Selective vascular clamping, which only controls the afferent blood flow of the resected liver, could be a valuable alternative, provided that blood loss is not increased because the opposite liver remains perfused. STUDY DESIGN The aim of the study was to assess the safety of selective vascular clamping in 43 patients who underwent 36 right hepatectomies and 7 left hepatectomies for lesions located peripherally within the liver. Blood transfusions, hepatic tests, morbidity, mortality, and hospital stay were evaluated. RESULTS Selective vascular clamping was efficient in 34 of the 43 attempts (79%), but bleeding from the contralateral liver required conversion to portal triad damping in 9 patients (21%). Median blood transfusions were 0 units (range 0 to 4 U), and 28 patients (65%) did not require transfusions. Postoperative laboratory tests showed that larger changes occurred at day 1 and tended to return to preoperative values at the end of the first postoperative week. Median time of hospitalization was 10 days (range 7 to 28 days). Postoperative course was uneventful in 35 patients (81%). Nonlethal complications occurred in 7 patients (16.3%). One patient (2%) with massive hepatic steatosis died of liver failure after right hepatectomy. CONCLUSIONS Selective vascular clamping is a safe alternative to total inflow occlusion for major hepatectomies applicable in 80% of selected patients with peripheral liver tumors.
