Effect of donor warm ischemia time during graft extraction in right lobe robotic donor hepatectomy on recipient outcomes-A propensity score matched analysis. Am J Transplant 2024:S1600-6135(24)00425-8. [PMID: 38992497 DOI: 10.1016/j.ajt.2024.07.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2024] [Revised: 06/29/2024] [Accepted: 07/04/2024] [Indexed: 07/13/2024]
Abstract
One of the concerns specific to minimally invasive donor hepatectomy (MIDH) is the prolonged time required for graft extraction after completion of the donor hepatectomy (donor warm ischemia time [DWIT]). There has never been an objective evaluation of minimally invasive donor hepatectomy-DWIT on allograft function in living donor liver transplantation. We evaluated the effect of DWIT following robotic donor hepatectomy (RDH) on recipient outcomes and compared them with a matched cohort of open donor hepatectomy (ODH). Demographic, perioperative, and recipient's postoperative outcome data for all right lobe (RL)-RDH performed between September 2019 and July 2023 were analyzed and compared with a propensity score matched cohort (1:1) of RL-ODH from the same time period. Of a total of 103 RL-RDH and 446 RL-ODH, unmatched and propensity score matched analysis (1:1) revealed a significantly longer DWIT in the RDH group as compared to the ODH group (9.33 ± 3.95 vs 2.87 ± 2.13, P < .0001). This did not translate into any difference in the rates of early allograft dysfunction (EAD), biliary complications, major morbidity, or overall 1-and 3-month survival. The receiver operating characteristic curve analysis threshold for DWIT-early allograft dysfunction was 9 minutes (area under receiver operating characteristic: 0.67, sensitivity = 80%, specificity = 53.8%). We show that prolonged DWIT within an acceptable range in RDH does not have deleterious effects on short-term recipient outcomes. Further long-term studies are required to confirm our findings, especially with regard to nonanastomotic biliary complications.

The Effect of Pringle Maneuver Applied during Living Donor Hepatectomy on the Ischemia-Reperfusion Injury Observed in the Donors and Recipients. MEDICINA (KAUNAS, LITHUANIA) 2024; 60:649. [PMID: 38674295 PMCID: PMC11051728 DOI: 10.3390/medicina60040649] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/15/2024] [Revised: 04/06/2024] [Accepted: 04/12/2024] [Indexed: 04/28/2024]
Abstract
Background and Objectives: The aim of this study is to evaluate the clinical and laboratory changes of ischemia and reperfusion injury in the remnant livers of donors with and without Pringle maneuver. Furthermore, we evaluated the recipients who have been transplanted with liver grafts from these donors. Methods and Materials: A total of 108 patients (54 living liver donors and 54 liver recipients) who underwent donor hepatectomy and recipients who living donor liver transplantation, were included in this randomized double-blind study between February 2021 and June 2021. The donors were divided into two groups: Pringle maneuver applied (n = 27) and Pringle maneuver not applied (n = 27). Similarly, recipients with implanted liver obtained from these donors were divided into two groups as the Pringle maneuver was performed (n = 27) and not performed (n = 27). Blood samples from donors and recipients were obtained on pre-operative, post-operative 0 h day (day of surgery), post-operative 1st day, post-operative 2nd day, post-operative 3rd day, post-operative 4th day, post-operative 5th day, and liver tissue was taken from the graft during the back table procedures. Liver function tests and complete blood count, coagulation tests, IL-1, IL-2, IL-6, TNF-α, and β-galactosidase measurements, and histopathological findings were examined. Results: There was no statistically significant difference in the parameters of biochemical analyses for ischemia-reperfusion injury at all periods in the donors with and without the Pringle maneuver. Similarly, there was no statistically significant difference between in the recipients in who received liver grafts harvested with and without the Pringle maneuver. There was no statistically significant difference between the two recipient groups in terms of perioperative bleeding and early bile duct complications (p = 0.685). In the histopathological examinations, hepatocyte damage was significantly higher in the Pringle maneuver group (p = 0.001). Conclusions: Although the histological scoring of hepatocyte damage was found to be higher in the Pringle maneuver group, the Pringle maneuver did not augment ischemia-reperfusion injury in donors and recipients that was evaluated by clinical and laboratory analyses.

Abstract
Background The pringle manoeuvre is commonly used during hepatectomy, which may cause ischaemia-reperfusion injury and transient liver dysfunction. Post-operative liver transaminases are often used to assess ischaemia-reperfusion injury, although there is conflicting evidence on survival outcomes. The primary aim was to assess post-operative alanine aminotransferase (ALT) with survival outcomes. Secondary aims were to assess ALT level with the length of stay and overall complications. Methods Post-operative day 2 ALT levels of five times the upper limit of normal (i.e. 280 U/L) were considered as clinically significant transaminitis. Kaplan-Meier survival curves were studied using log-rank analysis to identify the predictors of overall survival (OS) and recurrence-free survival (RFS). Results Out of 752 patients who underwent hepatectomy, 527 (70.1%) patients had low ALT (<280 U/L) and 225 (29.9%) patients had high ALT on day 2 post-op. Post-operative ALT did not affect OS (P = 0.883) or RFS (P = 0.063). Factors associated with a worse OS and RFS on multivariate analysis were pre-operative chemotherapy, number of tumours and largest tumour size (>4 cm). A high post-operative ALT was not associated with the increased length of stay or more complications. Conclusions Post-operative ALT does not affect survival outcomes post-hepatectomy for colorectal liver metastases.

Abstract
Living donor liver transplantation was first developed to mitigate the limited access to deceased donor organs in Asia in the 1990s. This alternative liver transplantation method has become a widely practiced and established transplantation option for adult patients suffering with end-stage liver disease, and it has successfully helped address the shortage of deceased donors. The Society for the Advancement of Transplant Anesthesia and the Korean Society of Transplantation Anesthesiologists jointly reviewed published studies on the perioperative management of adult live liver donors undergoing donor hemi-hepatectomy. The goal of the review is to offer transplant anesthesiologists and critical care physicians a comprehensive overview of the perioperative management of adult live donors. We featured the current status, donor selection process, outcomes and complications, surgical procedure, anesthetic management, Enhanced Recovery After Surgery protocols, avoidance of blood transfusion, and considerations for emergency donation. Recent surgical advances, including laparoscopic donor hemi-hepatectomy and robotic laparoscopic donor surgery, are also addressed.

Abstract
BACKGROUND Hepatic estrogen signaling, which is important in liver injury/recovery, is determined by the level of systemic estrogen and hepatic estrogen receptor. We aimed to evaluate whether female's advantage in the tolerance of hepatic ischemia-reperfusion injury decreases according to the age of 40 y (systemic estrogen decrease) and macrosteatosis (hepatic estrogen receptor decrease). METHODS We included 358 living liver donors (128 females and 230 males). The tolerance of hepatic ischemia-reperfusion injury was determined by the slope of the linear regression line modeling the relationship between the duration of intraoperative hepatic ischemia and the peak postoperative transaminase level. Estrogen receptor content was measured in the biopsied liver samples using immunohistochemistry. RESULTS In the whole cohort, the regression slope for aspartate transaminase was comparable between females and males (P=0.940). Within the subgroup of ≤40 y donors, the regression slope was significantly smaller in females (P=0.031), whereas it was comparable within >40 y donors (P=0.867). Within the subgroup of ≤40 y non-macrosteatotic donors, the regression slope was significantly smaller in females in univariable (P=0.002) and multivariable analysis (P=0.006), whereas the sex difference was not found within ≤40 y macrosteatotic donors (P=0.685). Estrogen receptor content was significantly greater in females within ≤40 y non-macrosteatotic donors (P=0.021), whereas it was not different in others of >40 y or with macrosteatosis (P=0.450). CONCLUSIONS The tolerance of hepatic ischemia-reperfusion injury was greater in females than in males only when they were <40 y and without macrosteatosis. The results were in agreement with hepatic estrogen receptor immunohistochemistry study.

Abstract
OBJECTIVE The Expert Consensus Guidelines initiative on MIDH for LDLT was organized with the goal of safe implementation and development of these complex techniques with donor safety as the main priority. BACKGROUND Following the development of minimally invasive liver surgery, techniques of MIDH were developed with the aim of reducing the short- and long-term consequences of the procedure on liver donors. These techniques, although increasingly performed, lack clinical guidelines. METHODS A group of 12 international MIDH experts, 1 research coordinator, and 8 junior faculty was assembled. Comprehensive literature search was made and studies classified using the SIGN method. Based on literature review and experts opinions, tentative recommendations were made by experts subgroups and submitted to the whole experts group using on-line Delphi Rounds with the goal of obtaining >90% Consensus. Pre-conference meeting formulated final recommendations that were presented during the plenary conference held in Seoul on September 7, 2019 in front of a Validation Committee composed of LDLT experts not practicing MIDH and an international audience. RESULTS Eighteen Clinical Questions were addressed resulting in 44 recommendations. All recommendations reached at least a 90% consensus among experts and were afterward endorsed by the validation committee. CONCLUSIONS The Expert Consensus on MIDH has produced a set of clinical guidelines based on available evidence and clinical expertise. These guidelines are presented for a safe implementation and development of MIDH in LDLT Centers with the goal of optimizing donor safety, donor care, and recipient outcomes.

Abstract
Liver transplantation is a life-saving therapy for patients with end-stage liver disease. Living donation is a critical source of organs throughout the world. Reducing donor morbidity and mortality is of utmost importance while maintaining access to liver transplantation for recipients. While laparoscopy was more rapidly utilized in donor nephrectomy, laparoscopy has been slower to develop for living donor hepatectomies due to the concerns about hemostasis, safety of the donor and quality of the graft. Pure minimal invasive approach has become a standard of care for left lateral sectionectomy (LLS) for pediatric recipients. In the past few years, a number of centers with significant laparoscopic and living donor experience have reported fully minimally invasive approach to hemi-hepatectomies. In this manuscript we discuss the experiences, lessons learned and path forward for laparoscopic and minimal invasive surgery(MIS) in donor hepatectomies (DH).

Abstract
Background The Pringle maneuver (PM) interrupts the blood flow through the hepatic artery and portal vein to help control bleeding. This study analyzes the effects of the intermittent Pringle maneuver (IPM) on the surgical process and postoperative liver injury. Methods This study retrospectively evaluated 182 hepatocellular carcinoma patients who underwent hepatectomy. In the IPM group, hepatic blood flow was intermittently interrupted via clamping, with cycles of 10 minutes of inflow occlusion followed by 5 minutes of reperfusion that were repeated until the end of the surgery. In the non-IPM group, liver resection was performed without hepatic vascular blockage. Results For postoperative complications, the incidence rates of ascites and pleural effusion in the IPM group were significantly lower than those in the non-IPM group. The postoperative hospitalization time in the IPM group was significantly lower than that in the non-IPM group (p=0.0008). On the first day after the operation, the platelet count was significantly lower (p=0.0381) but the prothrombin time (PT) (p=0.0195) and activated partial thromboplastin time (APTT) (p=0.0071) were significantly higher in the non-IPM group than those in the IPM group. At discharge, only albumin was significantly higher in the non-IPM group than that in the IPM group (p=0.0303). Regression analysis showed that a prolonged interruption time was related to increased ALT and AST levels on the first day after surgery, but not on the seventh day or at discharge. Conclusion The IPM does not cause additional liver damage during hepatectomy, and use of the IPM results in shorter hospital stays compared to surgery without using the IPM. The results of this study require further confirmation because of the retrospective design.

Abstract
BACKGROUND The adoption of laparoscopic techniques for living donor major hepatectomy has been controversial issue. The aim of this study is to present the preliminary experience of laparoscopic right hepatectomy in China. METHODS All the donors receiving right hepatectomy for adult-to-adult living donor liver transplantation (LDLT) were divided into three groups: pure laparoscopic right hepatectomy (PLRH) group, hand-assisted right hepatectomy (HARH) group and open right hepatectomy (ORH) group. We compared the perioperative data and surgical outcomes of donors and recipients among three groups. RESULTS From November 2001 to May 2017, 295 donors have received right hepatectomy for LDLT in our center. Among them, 7 donors received PLRH, 26 donors received HARH and 262 donors received ORH. The operation time of PLRH group (509.3 ± 98.9 min) was longer than that of the HARH group (451.6 ± 89.7 min) and the ORH group (418.4 ± 81.1 min, p = 0.003). The blood loss was the least in the PLRH group (378.6 ± 177.1 mL), compared with that in the HARH group (617.3 ± 240.4 mL) and that in the ORH group (798.6 ± 483.7 mL, p = 0.0013). The postoperative hospital stay was shorter in the PLRH group (7, 7-10 days) than that in the HATH group (8.5, 7.5-12 days) and ORH group (11, 9-14 days; p = 0.001). Only one donor had pleural effusion (Grade I) and another one experienced pulmonary infection (Grade II). One recipient (14.3%) in the PLRH group occurred hepatic venous stenosis. CONCLUSIONS Laparoscopic approaches for right hepatectomy contribute to less blood loss, better cosmetic satisfaction, less severe complications, and faster rehabilitation. PLRH is a safe and feasible procedure, which must be performed in highly specialized centers with expertise of both LDLT and laparoscopic hepatectomy, and requires a hybrid-to-pure stepwise development.

Abstract
Minimally invasive surgery potentially reduces operative morbidities. However, pure laparoscopic approaches to donor hepatectomy have been limited by technical complexity and concerns over donor safety. Reduced-wound donor hepatectomy, either in the form of a laparoscopic-assisted technique or by utilizing a mini-laparotomy wound, i.e., hybrid approach, has been developed to bridge the transition to pure laparoscopic donor hepatectomy, offering some advantages of minimally invasive surgery. To date, pure laparoscopic donor left lateral sectionectomy has been validated for its safety and advantages and has become the standard in experienced centres. Pure laparoscopic approaches to major left and right liver donation have been reported for their technical feasibility in expert hands. Robotic-assisted donor hepatectomy also appears to be a valuable alternative to pure laparoscopic donor hepatectomy, providing additional ergonomic advantages to the surgeon. Existing reports derive from centres with tremendous experience in both laparoscopic hepatectomy and donor hepatectomy. The complexity of these procedures means an arduous transition from technical feasibility to reproducibility. Donor safety is paramount in living donor liver transplantation. Careful donor selection and adopting standardized techniques allow experienced transplant surgeons to safely accumulate experience and acquire proficiency. An international prospective registry will advance the understanding for the role and safety of pure laparoscopic donor hepatectomy.

Abstract
BACKGROUND Total laparoscopic living donor right hemihepatectomy (LDRH) has been successfully performed in several transplant centers. Here we report the first LDRH performed in mainland China and review current literature, focusing on perioperative donor evaluation and surgical procedure to secure donor safety. METHODS A 47-year-old man volunteered for living donation to his wife who suffered from sclerosing cholangitis-related liver cirrhosis and hepatocellular carcinoma. Donor height is 165 cm and weight is 65 kg, whereas the body mass index is 23.9. The CT volume evaluation showed that the graft-to-body weight ratio was 1.42%, and the remnant liver volume was 36.3% for right graft without middle hepatic vein (MHV). The anatomy of hepatic vein, artery, portal vein, and bile duct was normal. Preoperative liver function tests were normal. RESULTS Intraoperative biopsy result showed minimal steatosis. A transection was performed along the right side of the MHV. Two branches of MHV (V5 and V8) were <5 mm in diameter, and there was no need for reconstruction in the back table. Hilar dissection was meticulously performed. Right portal vein, hepatic artery, and bile duct were transected above the bifurcation. The right hepatic vein was transected by a laparoscopic linear stapler. The real graft volume was 660 mL, with a revised graft-to-body weight ratio of 1.14%. Warm ischemia time was about 4 minutes. The donor's postoperative course was uneventful. CONCLUSIONS Total LDRH has been proven to be technically feasible in selected adult donors. Following increased experience, it might be a safe and minimally invasive option for adult donors.

Postoperative peak transaminases correlate with morbidity and mortality after liver resection. HPB (Oxford) 2016; 18:915-921. [PMID: 27600437 PMCID: PMC5094483 DOI: 10.1016/j.hpb.2016.07.016] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/27/2016] [Revised: 07/25/2016] [Accepted: 07/28/2016] [Indexed: 12/12/2022]
Abstract
BACKGROUND Transaminase levels are usually measured as markers of hepatocellular injury following liver resection, but recent evidence was unclear on their clinical value. This study aimed to identify factors that determine peak postoperative transaminase levels and correlated transaminase levels to postoperative complications. STUDY DESIGN All liver resections performed at a single center between 2006 and 2015 were included in the analysis. Multivariate analysis was used to identify factors that determine peak ALT and AST levels and postoperative morbidity and mortality. An ALT and AST cutoff for the prediction of mortality was determined using receiver operating characteristic curves analysis. RESULTS A total of 539 resections were included. Clavien-Dindo grade III or higher complications, intraoperative transfusion, and operative duration were identified as determinants of peak transaminases. A peak AST cut-off value for predicting mortality was defined at 828 U/L, with an area under the curve of 0.81 (0.73-0.89). The cut-off was an independent predictor of mortality (P < 0.01) along with (intraoperative) transfusion (P < 0.01), fifty-fifty criteria (P < 0.01), and age (P < 0.01). CONCLUSION Postoperative transaminase levels are independent predictors of postoperative morbidity and mortality and therefore clinically relevant. Transaminase levels usually peak during the first 24 h after surgery and thus possess early prognostic power in terms of postoperative mortality.

Abstract
BACKGROUND Liver resection is a major surgery with significant mortality and morbidity. Specialists have tested various methods in attempts to limit blood loss, transfusion requirements, and morbidity during elective liver resection. These methods include different approaches (anterior versus conventional approach), use of autologous blood donation, cardiopulmonary interventions such as hypoventilation, low central venous pressure, different methods of parenchymal transection, different methods of management of the raw surface of the liver, different methods of vascular occlusion, and different pharmacological interventions. A surgeon typically uses only one of the methods from each of these seven categories. The optimal method to decrease blood loss and transfusion requirements in people undergoing liver resection is unknown. OBJECTIVES To assess the effects of different interventions for decreasing blood loss and blood transfusion requirements during elective liver resection. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, and Science Citation Index Expanded to September 2015 to identify randomised clinical trials. We also searched trial registers and handsearched the references lists of identified trials. SELECTION CRITERIA We included only randomised clinical trials (irrespective of language, blinding, or publication status) comparing different methods of decreasing blood loss and blood transfusion requirements in people undergoing liver resection. DATA COLLECTION AND ANALYSIS Two review authors independently identified trials and collected data. We assessed the risk of bias using Cochrane domains. We conducted a Bayesian network meta-analysis using the Markov chain Monte Carlo method in WinBUGS 1.4, following the guidelines of the National Institute for Health and Care Excellence Decision Support Unit guidance documents. We calculated the odds ratios (OR) with 95% credible intervals (CrI) for the binary outcomes, mean differences (MD) with 95% CrI for continuous outcomes, and rate ratios with 95% CrI for count outcomes, using a fixed-effect model or random-effects model according to model-fit. We assessed the evidence with GRADE. MAIN RESULTS We identified 67 randomised clinical trials involving a total of 6197 participants. All the trials were at high risk of bias. A total of 5771 participants from 64 trials provided data for one or more outcomes included in this review. There was no evidence of differences in most of the comparisons, and where there was, these differences were in single trials, mostly of small sample size. We summarise only the evidence that was available in more than one trial below. Of the primary outcomes, the only one with evidence of a difference from more than one trial under the pair-wise comparison was in the number of adverse events (complications), which was higher with radiofrequency dissecting sealer than with the clamp-crush method (rate ratio 1.85, 95% CrI 1.07 to 3.26; 250 participants; 3 studies; very low-quality evidence). Among the secondary outcomes, the only differences we found from more than one trial under the pair-wise comparison were the following: blood transfusion (proportion) was higher in the low central venous pressure group than in the acute normovolemic haemodilution plus low central venous pressure group (OR 3.19, 95% CrI 1.56 to 6.95; 208 participants; 2 studies; low-quality evidence); blood transfusion quantity (red blood cells) was lower in the fibrin sealant group than in the control (MD -0.53 units, 95% CrI -1.00 to -0.07; 122 participants; 2; very low-quality evidence); blood transfusion quantity (fresh frozen plasma) was higher in the oxidised cellulose group than in the fibrin sealant group (MD 0.53 units, 95% CrI 0.36 to 0.71; 80 participants; 2 studies; very low-quality evidence); blood loss (MD -0.34 L, 95% CrI -0.46 to -0.22; 237 participants; 4 studies; very low-quality evidence), total hospital stay (MD -2.42 days, 95% CrI -3.91 to -0.94; 197 participants; 3 studies; very low-quality evidence), and operating time (MD -15.32 minutes, 95% CrI -29.03 to -1.69; 192 participants; 4 studies; very low-quality evidence) were lower with low central venous pressure than with control. For the other comparisons, the evidence for difference was either based on single small trials or there was no evidence of differences. None of the trials reported health-related quality of life or time needed to return to work. AUTHORS' CONCLUSIONS Paucity of data meant that we could not assess transitivity assumptions and inconsistency for most analyses. When direct and indirect comparisons were available, network meta-analysis provided additional effect estimates for comparisons where there were no direct comparisons. However, the paucity of data decreases the confidence in the results of the network meta-analysis. Low-quality evidence suggests that liver resection using a radiofrequency dissecting sealer may be associated with more adverse events than with the clamp-crush method. Low-quality evidence also suggests that the proportion of people requiring a blood transfusion is higher with low central venous pressure than with acute normovolemic haemodilution plus low central venous pressure; very low-quality evidence suggests that blood transfusion quantity (red blood cells) was lower with fibrin sealant than control; blood transfusion quantity (fresh frozen plasma) was higher with oxidised cellulose than with fibrin sealant; and blood loss, total hospital stay, and operating time were lower with low central venous pressure than with control. There is no evidence to suggest that using special equipment for liver resection is of any benefit in decreasing the mortality, morbidity, or blood transfusion requirements (very low-quality evidence). Radiofrequency dissecting sealer should not be used outside the clinical trial setting since there is low-quality evidence for increased harm without any evidence of benefits. In addition, it should be noted that the sample size was small and the credible intervals were wide, and we cannot rule out considerable benefit or harm with a specific method of liver resection.

Abstract
BACKGROUND AND AIMS Intraoperative vascular occlusion techniques during liver surgeries have been performed and refined for decades. However, the impact of these techniques on postoperative peak ALT levels remains uncertain. Thus, we performed a literature review and meta-analysis to determine the impact of intraoperative vascular occlusion during liver surgery on postoperative peak ALT levels. METHODS A systematic literature search of the PubMed database was conducted to discover relevant controlled clinical trials. Studies that reported postoperative peak ALT values for both an observation group and a control group were included. The Q statistic and the I(2) index statistic were used to assess heterogeneity. Publication bias was evaluated using Egger's test and Orwin's fail-safe N test. RESULTS Of the 281 retrieved articles, 10 articles fulfilled the inclusion criteria. These 10 articles involved 12 randomized controlled trials with a total of 1443 records. The pooled estimation results indicated that intraoperative vascular occlusion significantly elevated postoperative peak ALT levels (test for SMD: Z = 4.09, P < 0.001; 95% CI: 0.59-1.68), with high heterogeneity (I(2) = 93.8%). Subgroup analysis revealed that intermittent inflow occlusion and Pringle's maneuver vascular occlusions may be the potential crucial factors. No obvious publication bias was detected by Egger's test (P = 0.541) or Orwin's fail-safe N test (Nfs0.05 = 2059.19). CONCLUSIONS Intraoperative vascular occlusion, especially intermittent inflow occlusion and Pringle's maneuver vascular occlusions, may be a potential risk factor that could lead higher postoperative peak ALT values than non-occlusion procedures for liver surgeries.

Abstract
BACKGROUND Various clamping procedures are used to decrease bleeding during liver resections but their effect on central venous pressure (CVP) remains unclear. The aim of this study was to assess the variations of the CVP during two different clamping procedures. METHODS We retrospectively reviewed 29 patients (19 males, 10 females) who had Pringle maneuver (PM) and clamping of the inferior vena cava below the liver (IVCC) during major liver resections. RESULTS Mean decrease of the CVP after PM, IVCC, and PM+IVCC was 0.84 ± 1.37, 2.17 ± 2.13 and 3.17 ± 2.56 cmH20, respectively (P=0.02, P<0.0001 and P<0.0001, respectively). IVCC was more effective in inducing a decrease of the CVP than PM alone (P<0.05). The combination of both PM and IVCC induced the greatest decrease but not to a level of significance compared to IVCC alone (P=0.25). CONCLUSION IVCC remains the more efficient procedure to lower the CVP. However, although PM is commonly used to control vascular inflow within the liver its significant influence on the CVP could participate to the reduction of bleeding during liver resections.

Abstract
INTRODUCTION Intraoperative haemorrhage remains one of the major risks during liver resection, and perioperative blood loss and blood transfusion are important factors affecting perioperative morbidity and mortality. The aim of this study is to compare treatment strategies aiming to decrease blood loss during hepatectomy. METHODS A systematic review of the literature was performed to identify randomised controlled trials reporting on the method of vascular occlusion, parenchymal transection, and management of the cut surface during liver resection. A Bayesian network meta-analysis was performed using WinBUGS. RESULTS Seven trials reporting on 496 participants randomised to seven treatment strategies were analysed. Continuous vascular occlusion resulted in lower blood loss compared to no vascular occlusion when parenchymal transection was performed with clamp-crush and no fibrin sealant was used for the cut surface. People undergoing liver resection by continuous vascular occlusion had decreased amounts of blood transfused than people with intermittent vascular occlusion when parenchymal transection was performed with clamp-crush and no fibrin sealant. There was no significant difference in proportion of people transfused, mortality, or hospital stay between the different strategies. There were significantly more serious adverse events when surgery was performed using radiofrequency dissecting sealer compared with standard clamp-crush method in the absence of vascular occlusion and fibrin sealant. CONCLUSIONS Continuous vascular occlusion during hepatectomy results in decreased blood loss and decreased blood transfusion requirements. Further studies are needed to compare treatment strategies aiming to decrease blood loss, defined by their method of vascular occlusion, parenchymal transection, and management of the cut surface.

Abstract
AIM The impact of intermittent inflow occlusion (Pringle maneuver) in living donor hepatectomy on the outcome of both the donor and the recipient is unknown. The aim of this study is to elucidate the safety and efficacy of Pringle maneuver in living donor hepatectomy. METHODS Twenty consecutive cases of living donors who underwent left hepatectomy were prospectively divided into two groups, with (Group A, n = 10) or without (Group B, n = 10) the Pringle maneuver during hepatectomy. Intraoperative blood loss, postoperative liver functions in the donors and recipient outcome were reviewed. RESULTS Median blood loss was significantly less in group A than in group B. Median alanine aminotransferase was significantly higher on postoperative day 1 in group A than in group B, but the difference was not significant at 7 days after surgery. Eight of 10 recipients in each group survived with good graft function with a median follow-up period of 20 months in group A and 19 months in group B. CONCLUSION The Pringle maneuver was safely applied in living donor hepatectomy, but the only benefit was the reduction of blood loss during the donor surgery, and no positive impact on the recipient outcome.

Abstract
Reducing blood loss is beneficial in living liver donor hepatectomy. Although it has been suggested that maintaining a low central venous pressure is important, it is known that low stroke volume variation may be associated with increased blood loss. Therefore, we compared the effect on blood loss of 40 patients randomly assigned to a high stroke volume variation group (maintaining 10-20% of stroke volume variation) vs 38 patients in a control group (maintaining < 10% stroke volume variation) during living-donor right hepatectomy. Mean (SD) blood loss during donor hepatectomy was significantly lower in the high stroke volume variation group than in the control group: 476 (131) ml vs 836 (341) ml, respectively (p < 0.001). Blood pressure and peri-operative laboratory values did not differ between the two groups. However, in the high stroke volume variation group, central venous pressure values were also significantly lower. We were unable to disentangle the effects of stroke volume variation and central venous pressure, but our results confirm that the two together appear beneficial.

Abstract
Intermittent hepatic inflow occlusion (IHIO) during liver graft procurement is known to confer protection against graft ischemia/reperfusion injury and thus may benefit the recipient's outcome. We evaluated whether the protective effect of IHIO differs with the presence of macrosteatosis (MaS) and with an increase or decrease in the cumulative occlusion time. The subgroup of 188 recipients who received grafts with MaS was divided into 3 groups according to the number of total IHIO rounds during graft procurement: no IHIO, n = 70; 1 to 2 rounds of IHIO, n = 50; and ≥3 rounds of IHIO, n = 68. Likewise, the subgroup of 200 recipients who received grafts without MaS was divided into 3 groups: no IHIO, n = 108; 1 to 2 rounds of IHIO, n = 40; and ≥3 rounds of IHIO, n = 52. The Cox model was applied to evaluate the association between the number of total IHIO rounds and recipient survival separately in the subgroup of MaS recipients and the subgroup of non-MaS recipients. Analyzed covariables included the etiology, Milan criteria, transfusion, immunosuppression, and others. In the subgroup of MaS recipients, 1 to 2 rounds of IHIO were favorably associated with recipient survival [hazard ratio (HR), 0.29; 95% confidence interval (CI), 0.10-0.80; P = 0.03 after Bonferroni correction], whereas ≥3 rounds of IHIO were not associated with recipient survival (HR, 0.56; 95% CI, 0.25-1.23). In the subgroup of non-MaS recipients, neither 1 to 2 rounds of IHIO (HR, 0.69; 95% CI, 0.30-1.61) nor ≥3 rounds of IHIO (HR, 0.91; 95% CI, 0.42-1.96) were associated with recipient survival. In conclusion, 1 to 2 rounds of IHIO may be used for the procurement of MaS grafts with potential benefit for recipient survival, whereas IHIO has a limited impact on recipient survival regardless of the cumulative occlusion time when it is used for non-MaS grafts.

Abstract
A safe use of intermittent hepatic inflow occlusion (IHIO) has been reported for living donor hepatectomy. However, it remains unclear whether the maneuver is safe in steatotic donors. In addition, the respective importance of macrosteatosis (MaS) and microsteatosis (MiS) is an important issue. Thus, we compared MiS and MaS with respect to the tolerance of hepatic ischemia/reperfusion (IR) injury induced by IHIO. One hundred forty-four donors who underwent a right hepatectomy were grouped according to the presence of MaS and MiS: a non-MaS group (n = 68) versus an MaS group (n = 76) and a non-MiS group (n = 51) versus an MiS group (n = 93). The coefficients of the regression lines between the cumulative IHIO time and the peak postoperative transaminase concentrations were used as surrogate parameters indicating the tolerance of hepatic IR injury. The coefficients were significantly greater for the MaS group versus the non-MaS group (4.12 ± 0.59 versus 2.22 ± 0.46 for alanine aminotransferase, P = 0.01). Conversely, the MiS and non-MiS groups were comparable. A subgroup analysis of donors who underwent IHIO for >30 minutes showed that MaS significantly increased the transaminase concentrations, whereas MiS had no impact. Also, IHIO for >30 minutes significantly increased the biliary complication rate for MaS donors (12.1% for ≤ 30 minutes versus 32.6% for >30 minutes, P = 0.04), whereas MiS donors were not affected. In conclusion, the tolerance of hepatic IR injury might differ between MaS livers and MiS livers. It would be rational to assign more clinical importance to MaS versus MiS. We further recommend limiting the cumulative IHIO time to 30 minutes or less for MaS donors undergoing right hepatectomy.

Abstract
BACKGROUND Liver resection is a major surgery with significant mortality and morbidity. Various methods have been attempted to decrease blood loss and morbidity during elective liver resection. These methods include different methods of vascular occlusion, parenchymal transection, and management of the cut surface of the liver. A surgeon typically uses only one of the methods from each of these three categories. Together, one can consider this combination as a treatment strategy. The optimal treatment strategy for liver resection is unknown. OBJECTIVES To assess the comparative benefits and harms of different treatment strategies that aim to decrease blood loss during elective liver resection. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, and Science Citation Index Expanded to July 2012 to identify randomised clinical trials. We also handsearched the references lists of identified trials. SELECTION CRITERIA We included only randomised clinical trials (irrespective of language, blinding, or publication status) where the method of vascular occlusion, parenchymal transection, and management of the cut surface were clearly reported, and where people were randomly assigned to different treatment strategies based on different combinations of the three categories (vascular occlusion, parenchymal transection, cut surface). DATA COLLECTION AND ANALYSIS Two review authors identified trials and collected data independently. We assessed the risk of bias using The Cochrane Collaboration's methodology. We conducted a Bayesian network meta-analysis using the Markov chain Monte Carlo method in WinBUGS 1.4 following the guidelines of the National Institute for Health and Care Excellence Decision Support Unit guidance documents. We calculated the odds ratios (OR) with 95% credible intervals (CrI) (which are similar to confidence intervals in the frequentist approach for meta-analysis) for the binary outcomes and mean differences (MD) with 95% CrI for continuous outcomes using a fixed-effect model or random-effects model according to model-fit. MAIN RESULTS We identified nine trials with 617 participants that met our inclusion criteria. Interventions in the trials included three different options for vascular occlusion, four for parenchymal transection, and two for management of the cut liver surface. These interventions were combined in different ways in the trials giving 11 different treatment strategies. However, we were only able to include 496 participants randomised to seven different treatment strategies from seven trials in our network meta-analysis, because the treatment strategies from the trials that used fibrin sealant for management of the raw liver surface could not be connected to the network for any outcomes. Thus, the trials included in the network meta-analysis varied only in their approaches to vascular exclusion and parenchymal transection and none used fibrin sealant. All the trials were of high risk of bias and the quality of evidence was very low for all the outcomes. The differences in mortality between the different strategies was imprecise (seven trials; seven treatment strategies; 496 participants). Five trials (six strategies; 406 participants) reported serious adverse events. There was an increase in the proportion of people with serious adverse events when surgery was performed using radiofrequency dissecting sealer compared with the standard clamp-crush method in the absence of vascular occlusion and fibrin sealant. The OR for the difference in proportion was 7.13 (95% CrI 1.77 to 28.65; 15/49 (adjusted proportion 24.9%) in radiofrequency dissecting sealer group compared with 6/89 (6.7%) in the clamp-crush method). The differences in serious adverse events between the other groups were imprecise. There was a high probability that 'no vascular occlusion with clamp-crush method and no fibrin' and 'intermittent vascular occlusion with Cavitron ultrasonic surgical aspirator and no fibrin' are better than other treatments with regards to serious adverse events. Quality of life was not reported in any of the trials.The differences in the proportion of people requiring blood transfusion was imprecise (six trials; seven treatments; 446 participants). Two trials (three treatments; 155 participants) provided data for quantity of blood transfused. People undergoing liver resection by intermittent vascular occlusion had higher amounts of blood transfused than people with continuous vascular occlusion when the parenchymal transection was carried out with the clamp-crush method and no fibrin sealant was used for the cut surface (MD 1.2 units; 95% CrI 0.08 to 2.32). The differences in the other comparisons were imprecise (very low quality evidence). Three trials (four treatments; 281 participants) provided data for operative blood loss. People undergoing liver resection using continuous vascular occlusion had lower blood loss than people with no vascular occlusion when the parenchymal transection was carried out with clamp-crush method and no fibrin sealant was used for the cut surface (MD -130.9 mL; 95% CrI -255.9 to -5.9). None of the trials reported the proportion of people with major blood loss.The differences in the length of hospital stay (six trials; seven treatments; 446 participants) and intensive therapy unit stay (four trials; six treatments; 261 participants) were imprecise. Four trials (four treatments; 245 participants) provided data for operating time. Liver resection by intermittent vascular occlusion took longer than liver resection performed with no vascular occlusion when the parenchymal transection was carried out with Cavitron ultrasonic surgical aspirator and no fibrin sealant was used for the cut surface (MD 49.6 minutes; 95% CrI 29.8 to 69.4). The differences in the operating time between the other comparisons were imprecise. None of the trials reported the time needed to return to work. AUTHORS' CONCLUSIONS Very low quality evidence suggested that liver resection using a radiofrequency dissecting sealer without vascular occlusion or fibrin sealant may increase serious adverse events and this should be evaluated in further randomised clinical trials. The risk of serious adverse events with liver resection using no special equipment compared with more complex methods requiring special equipment was uncertain due to the very low quality of the evidence. The credible intervals were wide and considerable benefit or harm with a specific method of liver resection cannot be ruled out.
