Abstract
BACKGROUND This study aimed to investigate the usefulness of a weight-loss program (WLP) in patients with a high body mass index (BMI) prior to liver resection (Hx) for hepatocellular carcinoma (HCC). METHODS Among 445 patients with HCC who underwent initial Hx between 2000 and 2020, 19 with a high BMI (≥25.0) were enrolled in our WLP since 2014. For calorie restriction, the amount of energy consumed was calculated as the standard body weight (SBW) kg × 20-25 kcal/day. Protein mass was calculated as SBW kg × 1.0-1.2 g/day to maintain skeletal muscle mass. Patients also performed both aerobic and resistance exercises. The before-and-after changes were compared, and the effect of WLP on the short- and long-term results was investigated. RESULTS The average length of WLP was 21 days, and weight loss was successfully achieved in all patients. Body fat mass was reduced during the program, while skeletal muscle mass was maintained. WLP led to improvements in liver function and fibrotic markers, without tumor progression. There were no postoperative complications (≥Clavien-Dindo [CD] III). A retrospective comparison between with and without WLP using propensity score-matching analysis revealed that WLP group showed better NLR value, however, there were no significant differences in both short and long-term outcomes after Hx based on participation in the WLP. CONCLUSIONS WLP with multidisciplinary intervention improved immune-nutrition status and liver function of obese patients. WLP had not affected both short and long-term outcomes after Hx.

Abstract
BACKGROUND Data on the effect of body mass index on laparoscopic liver resections are conflicting. We performed this study to investigate the association between body mass index and postoperative outcomes after laparoscopic major hepatectomies. METHODS This is a retrospective review of 4,348 laparoscopic major hepatectomies at 58 centers between 2005 and 2021, of which 3,383 met the study inclusion criteria. Concomitant major operations, vascular resections, and previous liver resections were excluded. Associations between body mass index and perioperative outcomes were analyzed using restricted cubic splines. Modeled effect sizes were visually rendered and summarized. RESULTS A total of 1,810 patients (53.5%) had normal weight, whereas 1,057 (31.2%) were overweight and 392 (11.6%) were obese. One hundred and twenty-four patients (3.6%) were underweight. Most perioperative outcomes showed a linear worsening trend with increasing body mass index. There was a statistically significant increase in open conversion rate (16.3%, 10.8%, 9.2%, and 5.6%, P < .001), longer operation time (320 vs 305 vs 300 and 266 minutes, P < .001), increasing blood loss (300 vs 300 vs 295 vs 250 mL, P = .022), and higher postoperative morbidity (33.4% vs 26.3% vs 25.0% vs 25.0%, P = .009) in obese, overweight, normal weight, and underweight patients, respectively (P < .001). However, postoperative major morbidity demonstrated a "U"-shaped association with body mass index, whereby the highest major morbidity rates were observed in underweight and obese patients. CONCLUSION Laparoscopic major hepatectomy was associated with poorer outcomes with increasing body mass index for most perioperative outcome measures.

Abstract
Laparoscopic liver resection (LLR) is widely accepted in the surgical treatment of hepatocellular carcinoma (HCC) through international consensus conferences and the development of difficulty classifications. LLR has been reported to result in earlier postoperative recovery and fewer postoperative complications than open liver resection (OLR) for HCC. However, the prevalence of liver cirrhosis, obesity, the elderly, HCC recurrence (repeat liver resection), and major resection must be considered for LLR for HCC. Some systematic reviews, meta-analysis studies, and large cohort studies indicated that LLR is technically feasible for selected patients with HCC with these factors that led to less intraoperative blood loss, fewer transfusions and postoperative complication incidences, and shorter hospital stays than OLR. Furthermore, some reported LLR prevents postoperative loss of independence. No difference was reported in long-term outcomes among patients with HCC who underwent LLR and OLR; however, some recent reports indicated better long-term outcomes with LLR. In recent years, robot-assisted liver resection (RALR) has gradually become popular, and its short- and long-term results for HCC are not different from those of LLR. Additionally, RALR is expected to become the mainstay of minimally invasive surgery in the future.

Abstract
BACKGROUND The Textbook Outcome (TO) is a quality indicator accounting for both efficacy and safety. Herein, we aimed to assess TO in patients with hepatocellular carcinoma (HCC) undergoing percutaneous radiofrequency ablation (RFA). METHODS All consecutive patients undergoing RFA for HCC between 2014 and 2020, were included. TO was defined as 1) no post-RFA complications or mortality within 30 days after RFA, 2) no prolonged hospital stay 3) no 30-day readmission and 4) the achievement of a complete response (CR) of the target lesion/s at 1-month. RESULTS Overall, 50.3% of 376 patients fulfilled all the quality indicators to achieve TO. Probabilities of TO achievement decreased in presence of moderate comorbidities (odds ratio[OR]:0.43; 95%C.I.:0.22-0.80;p=0.008), a performance status of 1 (OR: 0.58;95%C.I.:0.37-0.89; p=0.013), the treatment of 2 nodules (OR: 0.71; 95%C.I.:0.41-0.98; p=0.048) or ≥3 nodules (OR: 0.41; 95%C.I.: 0.22 - 0.78; p = 0.007); the treatment of 2-3cm nodules (OR:0.49;95%C.I.:0.31-0.79;p=0.003) or >3cm nodules (OR: 0.36;95%C.I.:0.18-0.73;p=0.004). Risk-stratification provided TO achievement ranging between 77.9% and 14.3%. Patients with TO also had improved survival (p = 0.028). CONCLUSION About half of patients get TO from RFA. Stratification by clinical and tumoral characteristic should aid provision of RFA in clinical practice, facilitating patient information and providing reference values for future comparative studies.

Abstract
BACKGROUND Assessment of quality in the perioperative period is critical to ensure good patient care. Textbook outcomes (TO) have been proposed to combine several parameters into a single defined quality metric. The association of preoperative body mass index (BMI) with incidences of achieving or not achieving TO (non-TO) among patients undergoing hepatectomy for hepatocellular carcinoma (HCC) was characterized. METHODS Patients who underwent curative-intent hepatectomy for HCC between 2015 and 2018 were identified from a multicenter database. These patients were divided into three groups based on preoperative BMI: low-BMI (≤ 18.4 kg/m2), normal-BMI (18.5-24.9 kg/m2), and high-BMI (≥ 25.0 kg/m2). The incidences of non-TO among these three groups were compared. Multivariate analyses were performed to identify whether there was any independent association between preoperative BMI and non-TO. RESULTS Among 1206 patients, 100 (8.3%), 660 (54.7%), and 446 (37.0%) were in the low-BMI, normal-BMI, and high-BMI groups, respectively. The incidence of non-TO was 65.6% in the whole cohort. The incidence of non-TO was significantly higher among patients in the low- and high-BMI cohorts versus the normal-BMI cohort (75.0% and 74.7% versus 58.0%, both P < 0.01). After adjustment of other confounding factors on multivariate analysis, low-BMI and high-BMI were independently associated with higher incidences of non-TO compared with normal-BMI (OR: 1.98 and 2.27, both P < 0.05). CONCLUSIONS Two out of three patients did not achieve TO after hepatectomy for HCC. Both preoperative low-BMI and high-BMI were independently associated with lower odds to achieve optimal TO following HCC resection.

Abstract
AIM This study aimed to elucidate the effects of laparoscopic liver resection (LLR) vs open liver resection (OLR) for major complications (Clavien-Dindo classification grade ≥ IIIa) in obese individuals with hepatocellular carcinoma (HCC). METHODS The clinical records of 339 and 733 patients who underwent LLR and OLR, respectively, for HCC between 2000 and 2019 were retrospectively reviewed. Body mass index (BMI) groups were classified according to the definitions of the World Health Organization: underweight group, BMI ≤ 18.4 kg/m2 (LLR vs OLR: 27 vs 47); normal weight, BMI 18.5-24.9 kg/m2 (211 vs 483); overweight, BMI 25.0-29.9 kg/m2 (85 vs 181); and obese, BMI ≥ 30.0 kg/m2 (16 vs 22). The effects of obesity on major complications after LLR and OLR were investigated. RESULTS In total, 18 (5.3%) and 127 (17.3%) patients presented with major complications after LLR and OLR, respectively. There was no significant difference in the incidence of major complications after OLR in the four BMI groups. However, a stepwise decrease in the incidence of major complications after LLR was observed from the underweight to the obese group. In addition, a multivariate analysis revealed that increased BMI was an independent preventive factor for major complications after LLR (P = .026, odds ratio: 0.84). The estimated adjusted risk of major postoperative complications decreased with increased BMI in the LLR group, while the risk did not decrease in the OLR group (P for interaction = .048). CONCLUSION Laparoscopic liver resection is beneficial for obese patients and is superior to OLR.

Abstract
BACKGROUND This systematic review and meta-analysis aimed to compare the outcomes of curative therapy (resection, transplantation, ablation) for hepatocellular carcinoma (HCC) arising from non-alcoholic fatty liver disease (NAFLD) and non-NAFLD etiologies. METHODS A systematic search of PubMed, EMBASE and Cochrane Library was conducted for studies comparing survival, peri- and post-operative outcomes. Quality assessment was performed using the Newcastle-Ottawa scale. RESULTS Findings for 5579 patients were pooled across 9 studies and examined. Analysis demonstrated improved disease-free survival (DFS; HR 0.85, 95% CI 0.74-0.98, p = 0.03) and overall survival (OS; HR 0.87; 95% CI 0.81-0.93; p < 0.0001) in NAFLD-HCC patients undergoing liver resection as compared to non-NAFLD HCC patients. NAFLD-HCC patients undergoing all forms of curative therapy were similarly associated with improved OS (HR 0.96; 95% CI 0.86-1.06; p = 0.40) and DFS (HR 0.85; 95% CI 0.74-0.98; p = 0.03), albeit results being significant only for DFS. Only 2 studies reported higher rates of peri- and post-operative complications in patients with NAFLD-HCC. Significant inter-study heterogeneity precluded further analysis. CONCLUSION NAFLD-HCC patients can enjoy long-term survival benefit with aggressive curative therapy. Peri- and post-operative morbidity should be mitigated with pre-operative optimization of comorbidities, and deliberately close post-operative monitoring.

Abstract
BACKGROUND Laparoscopic liver resection is gaining momentum; however, there is limited evidence on its efficacy and safety in obese patients. The aim of this study was to examine the relationship between BMI and outcomes after laparoscopic liver resection (LLR) using a systematic review of the existing literature. METHODS A systematic search of Medline (Ovid 1946-present), PubMed (NCBI), Embase (Ovid 1966-present) and Cochrane Library was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement for parameters of LLR and BMI. Operative, post-operative and oncological outcomes were recorded. RESULTS Of 1460 abstracts, seven retrospective studies were analysed, published between 2015 and 2017 (study periods 1998-2017). Total patient cohort were classified as 481 obese and 1180 non-obese with a median age range of 42.5-69.4 years. Variations existed in definitions of obesity (Asia BMI >25 kg/m2 , Western BMI >30 kg/m2 ). Rates of conversion were examined in four studies (0-31%) with one reporting BMI >28 kg/m2 as an independent risk factor. Estimated blood loss and transfusion rates were similar. Operative time was increased in obese patients in one study (P = 0.02). Mortality rates ranged from 0% to 4.3% with no difference between BMI classes. No difference in major morbidity was demonstrated. Bile leak rates were increased in obese groups in one study (0-3.44%, P < 0.05). Wound infections were reported in five studies, with higher rates in obese patients (0-5.8% versus 0-1.9%). Tumour size was comparable in both groups. Completeness of resection was analysed in four studies with one study reporting increased R0 rates in obese patients (P = 0.012). CONCLUSION This systematic review highlights that current evidence shows LLR in obese patients is safe, however, further studies are required.

Abstract
Colorectal liver metastases (CRLM) affect over 50 % of all patients with colorectal cancer, which is the second leading cause of cancer in the western world. Resection of CRLM may provide cure and improves survival over chemotherapy alone. However, resectability of CLRM has to be decided in multidisciplinary tumor boards and is based on oncological factors, technical factors and patient factors. The advances of chemotherapy lead to the abolition of contraindications to resection in favor of technical resectability, but somatic mutations and molecular subtyping may improve selection of patients for resection in the future. Technical factors center around anatomy of the lesions, volume of the remnant liver and quality of the liver parenchymal. Multiple strategies have been developed to overcome volume limitations and they are reviewed here. The least investigated topic is how to select the right patients among an elderly and frail patient population for the large variety of technical options specifically for bi-lobar CRLM to keep 90-day mortality as low as possible. The review is an overview over the current state-of-the art and a systematic guide to the topic of resectability of CRLM for both clinicians and patients.

Abstract
BACKGROUND Body mass index (BMI) has been widely used as a prognostic indicator. The association between preoperative BMI and postoperative morbidity in patients with hilar cholangiocarcinoma (HCCA) has not been proved. This study aimed to identify the association between preoperative BMI and postoperative morbidity following radical resection of HCCA. METHODS Patients were divided into three groups according to preoperative BMI: low BMI (≤18.4 kg/m2 ), normal BMI (18.4-24.9 kg/m2 ), and high BMI (≥24.9 kg/m2 ). Baseline characteristics, operative variables, postoperative 30-day mortality, and morbidity were compared. Risk factors associated with postoperative morbidity were assessed using univariable and multivariable logistic analyses. RESULTS Among 260 patients, 183 (70.4%) had normal BMI, 32 (12.3%) had low BMI, and 45 (17.3%) had high BMI. Compared to the patients with normal-BMI, both low and high BMI patients exhibited a significantly higher postoperative morbidity (87.5% and 82.2% vs 63.9%, P = .019 and P = .025, respectively). Additionally, the multivariable analysis revealed that both low and high BMI patients remained independently associated with an increased risk of postoperative morbidity. (OR: 3.707, 95% CI: 1.080-12.725, P = .037; and OR: 2.858, 95% CI: 1.167-7.002, P = .022, respectively). CONCLUSION BMI is an independent risk factor for higher postoperative morbidity in patients who undergo surgical treatment of hilar cholangiocarcinoma.

Abstract
There seemed to be characteristic risk factors in cirrhotic patients for posthepatectomy complications because these patients have less hepatic reserve as compared with noncirrhotic patients. The aim of the current study was to identify these characteristic risk factors in cirrhotic patients. We performed 419 primary hepatectomies for hepatocellular carcinoma. The patients were divided into the cirrhotic group (n = 198) and the noncirrhotic group (n = 221), and the risk factors for posthepatectomy complications were compared between the groups. Thirty-six cirrhotic patients (18.2%) experienced Clavien's Grade III or more complications. Tumor size, intraoperative blood loss, duration of operation, major hepatectomy (two or more segments), and necessity of blood transfusion were found to be significant risk factors in univariate analyses. Multivariate analysis revealed that major hepatectomy and intraoperative blood loss were independent risk factors for posthepatectomy complications in patients with cirrhosis. On the other hand, the duration of operation was only an independent risk factor for posthepatectomy complication in noncirrhotic patients. Cirrhotic patients should avoid a major hepatectomy and undergo a limited resection preserving as much liver tissue as possible and meticulous surgical procedures to lessen intraoperative blood loss are mandatory to prevent major posthepatectomy complications.

Abstract
BACKGROUND Obesity is often associated with comorbidities that limit remnant liver recovery after hepatectomy. The extent to which obesity, in the absence of comorbidities, impacts surgical risk after hepatectomy is unknown. We hypothesized that an obese population without major comorbidities would not be at increased risk of adverse outcomes after hepatectomies. METHODS We performed a retrospective analysis identifying patients who underwent hepatectomies from the American College of Surgeons National Surgical Quality Improvement Program data set 2005-2017. Outcomes of interest included the following: mortality, any morbidity, critical care complications, and failure to discharge home. Body mass index (BMI) was the primary variable of interest, grouped as ≥35 and <35 based on bivariate tests of associations with candidate cut-off points. In attempt to isolate the effect of obesity on outcomes among patients "without major comorbidities" (WOC), we included patients without diabetes, chronic obstructive pulmonary disease, renal insufficiency, and nonsmokers; remaining patients were grouped as "with major comorbidities" (WC). Multivariable logistic regression was used to test whether obesity is independently associated with the outcomes of interest after adjustment for other covariates. RESULTS A total of 36,396 patients were included. There were 13,754 patients in the WOC group and 22,642 in the WC group. Among patients in the WOC group, the adjusted odds of mortality were 2.2 times higher for patients with a BMI ≥35 versus a BMI <35. Among the patients in the WC group, a BMI ≥35 was not a statistically significant predictor of mortality after adjustment for other covariates. Obese patients had increased odds of each outcome among the WOC group. CONCLUSIONS Our hypothesis was refuted by these data. In fact, the adverse effect of obesity was more evident among healthy patients.

Abstract
BACKGROUND Morbidity remains a common problem following hepatic resection. The aim of this study was to investigate the association between preoperative body mass index (BMI) and morbidity in patients undergoing liver resection for hepatocellular carcinoma (HCC). METHODS Patients were divided into three groups according to preoperative BMI: low-BMI (≤18.4 kg/m2), normal-BMI (18.5-24.9 kg/m2) and high-BMI (≥25.0 kg/m2). Baseline characteristics, operative variables, postoperative 30-day mortality and morbidity were compared. Univariable and multivariable analyses were performed to identify independent risk factors associated with postoperative morbidity. RESULTS Among 1324 patients, 108 (8.2%), 733 (55.4%), and 483 (36.5%) were low-BMI, normal-BMI, and high-BMI, respectively. There were no differences in postoperative 30-day mortality among patients based on BMI (P = 0.199). Postoperative 30-day morbidity was, however, higher in low-BMI and high-BMI patients versus patients with a normal-BMI (33.3% and 32.1% vs. 22.9%, P = 0.018 and P < 0.001, respectively). Following multivariable analysis low-BMI and high-BMI remained independently associated with an increased risk of postoperative morbidity (OR: 1.701, 95%CI: 1.060-2.729, P = 0.028, and OR: 1.491, 95%CI: 1.131-1.966, P = 0.005, respectively). Similar results were noted in the incidence of postoperative 30-day surgical site infection (SSI). CONCLUSION Compared with normal-BMI patients, low-BMI and high-BMI patients had higher postoperative morbidity, including a higher incidence of SSI after liver resection for HCC.

Abstract
In Europe, the prevalence of metabolic syndrome (MS) has reached the endemic rate of 25%. Non-alcoholic fatty liver disease (NAFLD) is the hepatic manifestation of MS. Its definition is histological, bringing together the different lesions associated with hepatic steatosis (fat deposits on more than 5% of hepatocytes) without alcohol consumption and following exclusion of other causes. MS and NAFLD are implicated in the carcinogenesis of hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC). At present, HCC and ICC involving MS represent 15-20% and 20-30% respectively of indications for hepatic resection in HCC and ICC. Moreover, in the industrialized nations NAFLD is tending to become the most frequent indication for liver transplantation. MS patients combine the operative risk associated with their general condition and comorbidities and the risk associated with the presence and/or severity of NAFLD. Following hepatic resection in cases of HCC and ICC complicating MS, the morbidity rate ranges from 20 to 30%, and due to cardiovascular and infectious complications, post-transplantation mortality is heightened. The operative risk incurred by MS patients necessitates appropriate management including: (i) precise characterization of the subjacent liver; (ii) an accurately targeted approach privileging detection and optimization of treatment taking into account the relevant cardiovascular risk factors; (iii) a surgical strategy adapted to the histology of the underlying liver, with optimization of the volume of the remaining (postoperative) liver.

Abstract
OBJECTIVES The influence of obesity on the outcomes of curative liver resection for malignancies remains controversial. We aimed to compare the in-hospital outcomes of liver resection for malignancy between obese and non-obese patients. DESIGN This was a population-based, retrospective, observational study using data from the Nationwide Inpatient Sample (NIS), the largest all-payer US inpatient care database. SETTING Hospitalisations of adults ≥18 years old with diagnoses of primary hepatobiliary malignancy or secondary malignant neoplasms of liver in the USA were identified from the NIS database between 2005 and 2014. PARTICIPANTS Data of 18 398 patients ≥18 years old and underwent liver resection without pancreatic resection in the NIS were extracted. All included subjects had primary hepatobiliary malignancy or secondary malignant neoplasms of the liver. Patients were divided into obese and non-obese groups. These groups were compared with respect to postoperative complications, length of hospital stay and hospital cost according to surgical extent and approach. INTERVENTIONS Patients were undergoing lobectomy of liver or partial hepatectomy. PRIMARY AND SECONDARY OUTCOME MEASURES The primary endpoints of this study were postoperative complications, length of hospital stay and hospital cost. RESULTS After adjustment, obese patients were significantly more likely to experience postoperative complications than were non-obese patients (adjusted OR 1.25, 95% CI 1.10 to 1.42), regardless of whether lobectomy or partial hepatectomy was performed. Furthermore, obesity was significantly associated with increased risk of postoperative complications in patients who underwent open liver resection, but not laparoscopic resection. No significant difference was observed in length of hospital stay or total hospital costs between obese and non-obese patients. CONCLUSIONS After adjustment for preoperative comorbidities and other potential confounders, obesity is significantly associated with greater risk of complications in patients undergoing open liver resection for malignancy, but not laparoscopic resection.

Abstract
BACKGROUND Whether preoperative bodyweight is associated with long-term prognosis in patients after liver resection for hepatocellular carcinoma (HCC) is controversial. This study aimed to investigate the relationship of patient weight with long-term recurrence and overall survival (OS) after curative liver resection for HCC. METHODS Data for patients with HCC who underwent curative liver resection between 2000 and 2015 in five centres in China were analysed retrospectively in three groups according to their preoperative BMI: underweight (BMI 18·4 kg/m2 or less), normal weight (BMI 18·5-24·9 kg/m2 ) and overweight (BMI 25·0 kg/m2 or above). Patients' baseline characteristics, operative variables and long-term survival outcomes were compared. Univariable and multivariable Cox regression analyses were performed to identify risk factors for OS and recurrence-free survival (RFS) after resection. RESULTS Of 1524 patients, 107 (7·0 per cent) were underweight, 891 (58·5 per cent) were of normal weight and 526 (34·5 per cent) were overweight. Univariable analyses showed that underweight and overweight patients had poorer OS (both P < 0·001) and RFS (both P < 0·001) than patients of normal weight. Multivariable Cox regression analysis also identified both underweight and overweight to be independent risk factors for OS (hazard ratio (HR) 1·22, 95 per cent c.i. 1·19 to 1·56, P = 0·019; and HR 1·57, 1·36 to 1·81, P < 0·001, respectively) and RFS (HR 1·28, 1·16 to 1·53, P = 0·028; and HR 1·34, 1·17 to 1·54, P < 0·001). CONCLUSION Underweight and overweight patients appear to have a worse prognosis than those of normal weight following liver resection for HCC.

Abstract
BACKGROUND Metabolic syndrome (MetS) is a group of clinicopathological manifestations. The outcome of liver surgery in metabolic syndrome-related hepatocellular carcinoma (MetS-HCC) still needs to be evaluated. We aim to clarify the outcomes following liver resection in patients with MetS-HCC compared those with hepatitis B virus-related HCC (HBV-HCC). METHODS All the consecutive patients undergoing hepatectomy for HCC between January 2009 and December 2012 were retrospectively considered. Patients were divided into three groups: MetS-HCC, MetS-HBV-HCC, and HBV-HCC. Data on clinical characteristics, postoperative complications, and long-term outcome were collected and analyzed. RESULTS A total of 1352 patients were included in this study. In MetS-HCC group, the severe morbidity rate was 33.33%, which was higher than that of HBV-HCC group (15.68%). In subgroup analysis, patients with MetS-HCC in American Joint Committee on Cancer (AJCC) stage I had superior DFS and OS when compared with those of the other two groups. CONCLUSIONS We should pay more attention to patients with MetS-HCC perioperatively due to the high rate of surgical complications. Nevertheless, curative treatment should be provided to patients with MetS.

Abstract
Klatskin's tumors, actually-redefined as perihilar cholangiocarcinoma (phCCA) do represent 50-70% of all CCAs and develop in a context of chronic inflammation and cholestasis of bile ducts. Surgical resection provides the only chance of cure for this disease but is technically challenging because of the complex, intimate and variable relationship between biliary and vascular structures at this location. Five years survival rates range between 25-45% (median 27-58 months) in case of R0 resection and 0-23% (median 12-21 months) in case of R1 resection respectively. It should be noted that the major costs of high radicality are represented by relative high morbidity and mortality rates (i.e., 20-66% and 0-9% respectively). Considering the fact that radical resection may represent the only curative treatment of phCCA, we focused our review on surgical planning and techniques that may improve resectability rates and outcomes for locally advanced phCCA. The surgical treatment of phCCA can be successful when following aspects have been fulfilled: (I) accurate preoperative diagnostic aimed to identify the tumor in all its details (localization and extension) and to study all the risk factors influencing a posthepatectomy liver failure (PHLF): i.e., liver volume, liver function, liver quality, haemodynamics and patient characteristics; (II) High end surgical skills taking in consideration the local extension of the tumor and the vascular invasion which usually require an extended hepatic resection and often a vascular resection; (III) adequate postoperative management aimed to avoid major complications (i.e., PHLF and biliary complications). These are technically challenging operations and must be performed in a high volume centres by hepato-biliary-pancreas (HBP)-surgeons with experience in microsurgical vascular techniques.

Abstract
Curative surgical resection (CSR) remains the most effective therapeutic intervention for patients with hepatocellular carcinoma (HCC); however, frequent post-surgical recurrence leads to high cancer related mortality. This study aimed to clarify the role of body mass index (BMI) and serum cholesterol level in predicting post-surgical outcomes in HCC patients after CSR. A total of 484 HCC patients including 213 BMIhigh and 271 BMIlow patients were included. Overall survival (OS) and recurrence-free survival (RFS) rates were examined in patients with differential BMI and serum cholesterol level. The analysis showed that significant different 1-, 3- and 5-year cumulative OS rates (P-value=0.015) and RFS rate (P-value=0.010) between BMIlow and BMIhigh patients. Further analysis in groups with differential serum cholesterol levels among BMIlow and BMIhigh patients indicated that the BMIlow/Chollow patients exhibited the significant lower cumulative OS and RFS rates in comparison with the remaining subjects (P-value=0.007 and 0.039 for OS and RFS rates, respectively). In conclusion, the coexistence of low BMI and low serum cholesterol level could serve as prognostic factors to predict post-operative outcomes in HCC patients undergoing surgical hepatectomy.

Abstract
Background Postoperative operative pulmonary complications (PPCs) after hepatic surgery are associated with increased length of hospital stays. Intraoperative blood transfusion, extensive resection and different comorbidities have been identified. Other parameters, like time of hepatic ischemia, have neither been clinically studied, though experimental studies show that hepatic ischemia can provide lung injury. The objective of this study was to determinate the risk factors of postoperative pulmonary complications (PPCs) after hepatic resection within 7 postoperative days. Method Ninety-four patients consecutively who underwent elective hepatectomy between January and December 2013. Demographic data, pathological variables, and preoperative, intraoperative, and postoperative variables had been prospectively collected in a data base. The dependant variables studied were the occurrence of PPCs, defined before analysis of the data. Results PPCs occurred in 32 (34%) patients. A multivariate analysis allowed identifying the risk factors for PPCs. On multivariate analysis, preoperative gamma-glutamyltransferase (GGT) elevation OR =5,12 [1,85-15,69] p = 0,002, liver ischemia duration OR = 1,03 [1,01-1,06] p = 0,01 and the intraoperative use of vasopressor OR = 4,40 [1,58-13,36] p = 0,006 were independently associated with PPCs. For every 10 min added in ischemia duration, the OR of the risk of PPCs was estimated to be 1.37 (CI95% = [1.08-1.81], p = 0.01). Conclusion Three risk factors for PPCs have been identified in a population undergoing liver resection: preoperative GGT elevation, ischemia duration and the intraoperative use of vasopressor. PPCs after liver surgery could be related to lung injury induced by liver ischemia reperfusion and not solely by direct infectious process. That could explain why factors influencing directly or indirectly liver ischemia were independently associated with PPCs.

Abstract
BACKGROUND Obese patients may present with metabolic abnormalities that impact liver regeneration. We sought to assess the impact of body mass index (BMI) on liver volume regeneration index (RI) and kinetic growth rate (KGR) among patients undergoing liver resection. METHODS The study included 102 patients undergoing major hepatectomy (≥3 segments) between July 2004 and April 2015 and stratified the patients by preoperative BMI, number of segments resected, and postoperative remnant liver volume (RLVp) to total liver volume ratio. Resected volume at operation was subtracted from total liver volume to calculate postoperative RLVp. RI was defined as the relative increase in RLV within 2 months [(RLV2m-RLVp)/RLVp] and 7 months [(RLV7m-RLVp)/RLVp] postoperatively; KGR was calculated as RI divided by time postoperatively (weeks). RESULTS Median patient age was 59.6 years (interquartile range 48.1-68.7 years), and most patients were men (52.0%). Liver failure was associated with the KGR at 2 months (KGR2m) and was greater among patients with KGR2m <2.5% per week (KGR <2.5%, 18.5% vs KGR ≥ 2.5%, 4.6%; P = .04). Although RI and KGR within 2 and 7 months postoperatively were similar among all patients, after excluding patients with fibrosis, obese (0.42% per week) and overweight patients (0.29% per week) had lesser KGR2-7m compared with patients of normal BMI (0.82% per week; P < .05). Additionally, risk of a major complication was greatest among obese patients (normal weight, 8.1% vs overweight, 12.9% vs obese, 29.4%; P = .04). CONCLUSION BMI did not impact liver regeneration during the first 2 months. In contrast, KGR per week between 2 and 7 months postoperatively was less among overweight and obese patients.

Abstract
New surgical procedures taking advantage of the regenerative abilities of the liver are being introduced as potential curative therapies to these patients either to provide auxiliary support while the native liver recovers or undergoes hypertrophy. For patients with hepatocellular carcinoma outside of the Milan criteria or bilobar colorectal metastases liver transplantation is not an option. Fulminant hepatic failure can be treated but requires life-long immunosuppression. These complex surgical procedures require high quality and directed imaging.

Abstract
Previous studies have reported the association between excess body mass index (BMI) and increased risk of hepatocellular carcinoma (HCC). However, whether BMI is associated with the prognosis and postoperative complications of HCC is still not clear.We searched PubMed and Embase for relevant studies published until the date of August 30, 2014. Additional studies were manually identified by searching reference lists of retrieved articles. Pooled hazard ratios (HRs) with 95% confidence intervals (95% CIs) for overall survival (OS), disease-free survival (DFS), and risk ratios (RRs) with 95% CIs for postoperative complications were calculated using random effects or fixed effects models according to heterogeneities between studies.A total of 14 studies were included in the present meta-analysis. The pooled results showed that excess BMI was not significantly associated with improved OS (HR = 0.94; 95% CI: 0.74-1.19, P = 0.588) or DFS (HR = 0.93; 95% CI: 0.79-1.10, P = 0.382). In addition, higher BMI was not associated with increased rate of a number of complications including ascites (RR = 1.25, 95% CI: 0.94-1.65, P = 0.119), bile leaks (RR = 1.22, 95% CI: 0.81-1.83, P = 0.345), and 30-day mortality (RR = 1.05, 95% CI: 0.57-1.96, P = 0.871). However, HCC patients with higher BMI had increased incidence of wound infections (RR = 2.17, 95% CI: 1.28-3.68, P = 0.004).BMI was not an independent prognostic factor for the evaluation of the prognosis in HCC patients, and it was not associated with postoperative complications except for wound infections that as significantly associated with higher BMI scores.

Abstract
BACKGROUND & AIMS The incidence of metabolic syndrome-related hepatocellular carcinoma (MS-HCC) is increasing worldwide. High resection risks are anticipated because of underlying steatohepatitis, but long-term results are unknown. To clarify the outcomes following liver resection in patients with MS-HCC and to compare the outcomes of MS-HCC to HCV-related HCC (HCV-HCC). METHODS All the consecutive patients undergoing liver resection for HCC in six high-volume HPB units between 2000 and 2012 were retrospectively considered. The patients with MS-HCC were identified and matched one-to-one with HCV-HCC patients without metabolic syndrome. Matching was based on age, cirrhosis, Child-Pugh class, portal hypertension, HCC number and diameter and liver resection extension. RESULTS Among 1563 patients undergoing liver resection for HCC in the study period, 96 (6.1%) had MS-HCC. They were matched with 96 HCV-HCC patients. All patients were Child-Pugh class A, 22.9% had cirrhosis. Forty-one patients per group (42.7%) required major hepatectomy. The MS-HCC group had a higher prevalence of steatohepatitis (25.0% vs. 9.4%, p=0.004). Operative mortality was 2.1% (1 MS-HCC, 3 HCV-HCC, p=0.621). Morbidity and liver failure rates were similar between the two groups. In the multivariate analysis, cirrhosis, major hepatectomy, and MELD >8, but not steatohepatitis, impacted severe morbidity and liver failure rates. The MS-HCC group had better 5-year overall survival (65.6% vs. 61.4%, p=0.031) and recurrence-free survival (37.0% vs. 27.5%, p=0.077). Independent negative prognostic factors were HCV-HCC, multiple HCC, microvascular invasion, and satellite nodules. CONCLUSIONS Liver resection is safe for MS-HCC, as for HCV-HCC. Cirrhosis, but not steatohepatitis, affects short-term outcomes. MS-HCC is associated with excellent long-term outcomes, better than HCV-HCC.

Abstract
Background Whether obesity affects surgical outcomes in patients with hepatocellular carcinoma (HCC) is controversial. Here we retrospectively evaluated the impact of obesity on outcomes in HCC patients after curative hepatectomy. Methods Patients with Child-Pugh A liver function who underwent curative hepatectomy between 2006 and 2010 were categorized as obese (BMI ≥25 kg/m2, n = 68) and non-obese (<25 kg/m2, n = 242). To reduce interference from baseline differences between the two groups, propensity score-matched analysis was performed in the ratio 1:2 using a caliper width of 0.1. Surgical outcomes were compared for 61 obese and 115 non-obese patients. Results Obese patients had higher levels of albumin and aspartate aminotransferase, and more solitary tumors compared to the non-obese patients (all P<0.05). In the propensity-matched cohort, baseline characteristics did not differ between the two groups (all P>0.05). Obese and non-obese patients had comparable 30-day mortality (1.6% vs. 2.6%, P = 1.000), 90-day mortality (3.3% vs. 4.3%, P = 1.000), and incidence of postoperative complications (19.7% vs. 18.3%, P = 0.819). Overall survival at 1, 3, and 5 years was similar for obese patients (83.6%, 63.6%, 41.6%) as for non-obese patients (80.9%, 65.9%, 49.1%; P = 0.358). Disease-free survival at 1, 3, and 5 years was also similar for obese patients (71.5%, 36.3%, 24.3%) as for non-obese ones (60.2%, 43.7%, 27.7%; P = 0.969). Conclusion Our propensity score-matched analysis strengthens the case that obesity does not adversely affect surgical outcomes of HCC patients undergoing curative hepatectomy.

Abstract
There are many methods to assess liver function, but none of them has been verified as fully effective. The purpose of this study is to establish a comprehensive method evaluating perioperative liver reserve function (LRF) in patients with primary liver cancer (PLC).In this study, 310 PLC patients who underwent liver resection were included. The cohort was divided into a training set (n = 235) and a validation set (n = 75). The factors affecting postoperative liver dysfunction (POLD) during preoperative, intraoperative, and postoperative periods were confirmed by logistic regression analysis. The equation for calculating the preoperative liver functional evaluation index (PLFEI) was established; the cutoff value of PLFEI determined through analysis by receiver-operating characteristic curve was used to predict postoperative liver function.The data showed that body mass index, international normalized ratio, indocyanine green (ICG) retention rate at 15 minutes (ICGR15), ICG elimination rate, standard remnant liver volume (SRLV), operative bleeding volume (OBV), blood transfusion volume, and operative time were statistically different (all P < 0.05) between 2 groups of patients with and without POLD. The relationship among PLFEI, ICGR15, OBV, and SRLV is expressed as an equation of "PLFEI = 0.181 × ICGR15 + 0.001 × OBV - 0.008 × SRLV." The cutoff value of PLFEI to predict POLD was -2.16 whose sensitivity and specificity were 90.3% and 73.5%, respectively. However, when predicting fatal liver failure (FLF), the cutoff value of PLFEI was switched to -1.97 whose sensitivity and specificity were 100% and 68.8%, respectively.PLFEI will be a more comprehensive, sensitive, and accurate index assessing perioperative LRF in liver cancer patients who receive liver resection. And keeping PLFEI <-1.97 is a safety margin for preventing FLF in PLC patients who underwent liver resection.

Abstract
BACKGROUND Despite the increasing prevalence of obesity, the impact of body weight on postoperative outcomes of laparoscopic liver resection (LLR) still remains poorly evaluated. The present study aimed to explore the impact of body mass index (BMI) on perioperative outcomes in patients undergoing LLR. STUDY DESIGN All patients undergoing LLR from January 2008 to December 2013 were retrospectively reviewed. BMI was subdivided into normal weight (<24.9 kg/m(2)), overweight (25.0-29.9 kg/m(2)), and obese (≥30.0 kg/m(2)). These three groups were compared in terms of demographic data, intraoperative factors, and postoperative outcomes. Logistic regression was used to determine odds ratios with 95% confidence intervals and evaluate BMI as an independent risk factor for morbidity. RESULTS Among 228 selected patients, 83 (36.4%) patients were overweight and 32 (14.0%) were obese. Despite higher rates of diabetes mellitus, hypertension, and ischemic heart disease with an increase in BMI, no significant difference in operative time, blood loss, and conversion rate was observed in the three groups. There were no significant differences in postoperative mortality rate between the groups (0.9 vs. 1.2 vs. 0%). The rate of overall complications (31.0 vs. 31.3 vs. 40.6%) and major complications (14.2 vs. 9.6 vs. 18.8%) did not differ in the three groups. Major hepatectomy (HR 6.810, CI 1.437-32.267, p = 0.016) and operative time >180 min (HR 2.639, CI 1.179-5.908, p = 0.018) were independently associated with postoperative complications. CONCLUSIONS The present study demonstrated that BMI does not negatively affect the postoperative short-term outcomes. Therefore, obesity and overweight should not be a contraindication for LLR.

Abstract
Metabolic syndrome (MS), which is defined as a constellation of clinico-biological features closely related to insulin-resistance has reached epidemic levels in Western Europe and Northern America. Non-alcoholic fatty liver disease (NAFLD) represents the hepatic manifestation of MS. As its incidence parallels that of MS, NAFLD is currently becoming one of the most frequent chronic liver diseases in Western countries. On one hand, MS favors the development of hepatocellular carcinoma (HCC) either through NAFLD liver parenchymal alterations (steatosis; steatohepatitis; fibrosis), or in the absence of significant underlying liver parenchyma changes. In this setting, HCC are often diagnosed incidentally, tend to be larger than in patients developing HCC on cirrhosis and therefore frequently require major liver resections. On the other hand, MS patients are at increased risk of both liver-related postoperative complications and increased cardiorespiratory events leading to non-negligible mortality rates following liver surgery. These deleterious effects seem to be related to the existence of impaired liver function even in the absence of severe fibrosis but also higher cardiorespiratory sensitivity in a setting of MS/NAFLD. Hence, specific medical and surgical improvements in the perioperative management of these patients are required. These include complete preoperative cardiorespiratory work-up and the wide use of preoperative liver volume modulation. Finally, the long-term prognosis after curative surgery for MS-related HCC does not seem to be worse than for other HCC occurring on classical chronic liver diseases. This is probably related to less aggressive tumor behavior with lower micro vascular invasion and decreased rates of poorly differentiated lesions. In this setting, several medical therapies including metformin could be of value in the prevention of both occurrence and recurrence of HCC.

Abstract
OBJECTIVE To evaluate the potential usefulness of perfusion computed tomography (CT) for the estimation of hepatic functional reserve in patients scheduled for surgical resection and to compare the results with those of the indocyanine green retention test results. METHODS Thirty-one patients with hepatobiliary malignancies were included. Perfusion CT and indocyanine green retention test were performed on the same day, and their results were compared using Pearson correlation test. RESULTS A strong correlation was found between perfusion CT time-to-peak values and indocyanine green retention rate at 15 minutes and indocyanine green plasma disappearance rate values (R, 0.789 and -0.790; R, 0.832 and -0.823, respectively; P < 0.0001). CONCLUSIONS Perfusion CT may be useful for the preoperative noninvasive estimation of hepatic functional reserve for patients undergoing liver resection.

Abstract
In order to achieve microscopic radical resection margins and thus better survival, surgical treatment of hepatic tumors has become more aggressive in the last decades, resulting in an increased rate of complex and extended liver resections. Postoperative outcomes mainly depend on the size and quality of the future remnant liver (FRL). Liver resection, when performed in the absence of sufficient FRL, inevitably leads to postresection liver failure. The current gold standard in the preoperative assessment of the FRL is computed tomography volumetry. In addition to the volume of the liver remnant after resection, postoperative function of the liver remnant is directly related to the quality of liver parenchyma. The latter is mainly influenced by underlying diseases such as cirrhosis and steatosis, which are often inaccurately defined until microscopic examination after the resection. Postresection liver failure remains a point of major concern that calls for accurate methods of preoperative FRL assessment. A wide spectrum of tests has become available in the past years, attesting to the fact that the ideal methodology has yet to be defined. The aim of this review is to discuss the current modalities available and new perspectives in the assessment of FRL in patients scheduled for major liver resection.

Abstract
Objective and Background Although many studies on evaluating the safety of liver resection in obese patients have been conducted, the results remain contradictory. The aim of our study was to investigate the safety of overweight and obese patients undergoing liver resection for hepatitis B-related hepatocellular carcinoma in a large sample. Methods In a retrospective cohort with 1543 hepatitis B-related hepatocellular carcinoma patients, the subjects were stratified into four groups according to their body mass index(BMI): obesity(BMI≥28), overweight(BMI:24.0–27.9), normal weight(BMI:18.5–23.9) and underweight(BMI<18.5). The Dindo–Clavien classification system was used for grading complications. Clinical characteristics and operative outcomes were compared among the four groups. Risk factors for postoperative complications were evaluated by multivariate analysis. Results According to the category criteria of the Working Group on Obesity in China (WGOC) criteria, 73(4.7%) obese, 412(26.7%) overweight, 982(63.6%) normal weight and 76(4.9%) underweight patients were included in our cohort. Overweight and obese patients had more preoperative comorbidities such as hypertension(P<0.001). Mortality, total complications and complications classified by Clavien system were similar among the four groups except that the underweight patients had fewer total complications. However, postoperative wound complication was more common in overweight and obese patients(6.3% vs 2.5%,P<0.001,11.0% vs 2.5%,P = 0.001). Multivariate analysis revealed that BMI was not an independently significant factor for postoperative complications. Conclusions Liver resection for obese and overweight patients is safe and BMI itself is not a risk factor for mortality and morbidity.

Abstract
The aim of this topic highlight is to review relevant evidence regarding the influence of the metabolic syndrome (MS) and its associated liver manifestation, non-alcoholic fatty liver disease (NAFLD), on the development of liver cancer as well as their impact on the results of major liver surgery. MS and NAFLD, whose incidences are significantly increasing in Western countries, are leading to a changing profile of the patients undergoing liver surgery. A MEDLINE search was performed for relevant articles using the key words "metabolic syndrome", "liver resection", "liver transplantation", "non alcoholic fatty liver disease", "non-alcoholic steatohepatitis" and "liver cancer". On one hand, the MS favors the development of primary liver malignancies (hepatocellular carcinoma and cholangiocarcinoma) either through NAFLD liver parenchymal alterations (steatosis, steatohepatitis, fibrosis) or in the absence of significant underlying liver parenchyma changes. Also, the existence of NAFLD may have a specific impact on colorectal liver metastases recurrence. On the other hand, the postoperative period following partial liver resection and liver transplantation is at increased risk of both postoperative complications and mortality. These deleterious effects seem to be related to the existence of liver specific complications but also higher cardio-vascular sensitivity in a setting of MS/NAFLD. Finally, the long-term prognosis after curative surgery joins that of patients operated on with other types of underlying liver diseases. An increased rate of patients with MS/NAFLD referred to hepatobiliary units has to be expected. The higher operative risk observed in this subset of patients will require specific improvements in their perioperative management.

Abstract
Extended hepatectomy, or liver transplantation of reduced-size graft, can lead to a pattern of clinical manifestations, namely “post-hepatectomy liver failure” and “small-for-size syndrome” respectively, that can range from mild cholestasis to irreversible organ non-function and death of the patient. Many mechanisms are involved in their occurrence but in the recent past, high portal blood flow through a relatively small liver vascular bed has taken a central role. Therefore, several techniques of inflow modulation have been attempted in cases of portal hyperperfusion first in liver transplantation, such as portocaval shunt, mesocaval shunt, splenorenal shunt, splenectomy or ligation of the splenic artery. However, high portal flow is not the only factor responsible, and before major liver resections, preoperative assessment of the residual liver function is necessary. Techniques such as portal vein embolization or portal vein ligation can be adopted to increase the future liver volume, preventing post-hepatectomy liver failure. More recently, a new surgical procedure, that combines in situ splitting of the liver and portal vein ligation, has gradually come to light, inducing remarkable hypertrophy of the healthy liver in just a few days. Further studies are needed to confirm this hypothesis and overcome one of the biggest issues in the field of liver surgery.

Abstract
INTRODUCTION Liver failure after hepatectomy remains the most feared postoperative complication. Many risk factors are already known, related to patient's comorbidities, underlying liver disease, received treatments and type of resection. Preoperative assessment of functional liver reserve must be a priority for the surgeon. METHODS Physiopathology of post-hepatectomy liver failure is not comparable to fulminant liver failure. Liver regeneration is an early phenomenon whose cellular mechanisms are beginning to be elucidated and allowing most of the time to quickly recover a functional organ. In some cases, microscopic and macroscopic disorganization appears. The hepatocyte hyperproliferation and the asynchronism between hepatocytes and non-hepatocyte cells mitosis probably play a major role in this pathogenesis. RESULTS Many peri- or intra-operative techniques try to prevent the occurrence of this potentially lethal complication, but a better understanding of involved mechanisms might help to completely avoid it, or even to extend the possibilities of resection. CONCLUSION Future prevention and management may include pharmacological slowing of proliferation, drug or physical modulation of portal flow to reduce shear-stress, stem cells or immortalized hepatocytes injection, and liver bioreactors. Everything must be done to avoid the need for transplantation, which remains today the most efficient treatment of liver failure.

Abstract
AIM The aim of this study was to determine the incidence and prognostic factors of postoperative liver failure in patients submitted to liver resection for colorectal metastases. METHOD Patients with CLM who underwent hepatectomy from 1998 to 2009 were included in retrospective analysis. Postoperative liver failure was defined using either the 50-50 criteria or the peak of serum bilirubin level above 7 mg/dL independently. RESULTS Two hundred and nine (209) procedures were performed in 170 patients. 120 surgeries were preceded by chemotherapy within six months. The overall morbidity rate was 53.1% and 90-day mortality was 2.3%. Postoperative liver failure occurred in 10% of all procedures, accounting for a mortality rate of 9.5% among this group of patients. In multivariate analysis, extent of liver resection, need of blood transfusion and more than eight preoperative chemotherapy cycles were independent prognostic factors of postoperative liver insufficiency. This complication was not related with the chemotherapy regimen used. CONCLUSION We conclude that postoperative liver failure has a relatively low incidence (10%) after CLM resection, but a remarkable impact on postoperative mortality rate. The amount of liver resected, the need of blood transfusion and extended preoperative chemotherapy are independent predictors of its occurrence and this knowledge can be used to prevent postoperative liver failure in a multidisciplinary approach.

Abstract
Liver function is a broad term, as the organ participates in a multitude of different physiological and biochemical processes, including metabolic, synthetic, and detoxifying functions. However, it is the function of the hepatocyte that is central to sustaining normal life and dealing with disease states. When the liver begins to fail in severely ill patients, it forecasts a terminal outcome. However, unlike the glomerular filtration rate which clearly quantifies the key renal function, at most practice sites, there is no clinically available quantitative test for liver function. Although it is commonplace to assess indirect evidence of that function (by measuring blood levels of its end products and by-products) and to detect an acute injury (by following rising transaminases), a widely available test that would directly measure hepatocellular function is lacking. This article reviews current knowledge on liver function studies and focuses on those nuclear medicine tests available to study the whole liver and regional liver function. The clinical application driving these tests, prediction of remnant liver function after partial hepatectomy for primary liver malignancy or metastatic disease, is addressed here in detail. The test was recently validated for this specific application and was shown to be better than the current standard of practice (computed tomography volumetry), particularly in patients with hepatic comorbidities like cirrhosis, steatosis, or cholestasis. Furthermore, early assessment of regional liver function increase after preoperative portal vein embolization becomes possible with this technology. The limiting factor to a wider acceptance of this test is based on the lack of clinical software that would allow calculation of liver function parameters. This article provides information that enables a clinical nuclear medicine facility to provide this test using readily available equipment. Furthermore, it addresses emerging clinical applications that are under investigation.

Abstract
BACKGROUND The regenerative capacity of the liver is an essential pre-condition for the successful application of partial hepatectomy. However, the actual kinetics of functional recovery remains unspecified and no adequate tool for its clinical monitoring has yet been available. METHODS Eighty-five patients receiving major hepatectomy were investigated from the preoperative evaluation until 12 weeks after surgery. Liver function was determined by the LiMAx test for the enzymatic capacity of cytochrome P450 1A2. Liver volume was determined by volumetric analysis of repeated computer tomography scans. Functional and volume recovery were compared during follow-up. RESULTS Major hepatectomy decreased liver function capacity to 35.7 ± 13.8% of preoperative function. It was shown that functional recovery already reaches 77.2 ± 33.5% of preoperative values within 10 days. The actual kinetics were dependent from the type and extent of hepatectomy. Complete functional restoration was achieved within 12 weeks, while liver volume still remained at 73.2 ± 14.8% of preoperative. A constant but interindividually variable correlation between function and volume was observed at all points in time. CONCLUSION Partial hepatectomy leads to fast and complete functional recovery, while volume recovery is delayed and remains often incomplete. The functional recovery is mainly influenced by the preoperative liver function, the residual liver volume, and by obesity.
