Abstract
BACKGROUND Liver parenchymal transection during robotic liver resection (RLR) remains a significant challenge due to the limited range of specialised instruments. This study introduces our 'Burn and Push' technique as a novel approach to address these challenges. METHODS A retrospective analysis was conducted on 20 patients who underwent RLR using the 'Burn and Push' technique at Virginia Commonwealth University Health System from November 2021 to August 2023. The study evaluated peri- and post-operative outcomes. RESULTS The median operation time was 241.5 min (range, 90-620 min), and the median blood loss was 100 mL (range, 10-600 mL). Major complications occurred in one case, with no instances of postoperative bleeding, bile leak, or liver failure. CONCLUSIONS The 'Burn and Push' technique is a viable and efficient alternative for liver parenchymal transection in RLR. Further research with larger sample sizes and consideration of the learning curve is necessary to validate these findings.

Abstract
BACKGROUND Post-COVID-19 cholangiopathy is an emerging cholestatic liver disease observed in patients recovering from severe COVID-19 infection. Its prognosis is poor, necessitating liver transplantation in some cases. This study aimed to investigate the outcomes of liver transplantation for post-COVID-19 cholangiopathy. METHODS Seven patients who underwent liver transplantation for post-COVID-19 cholangiopathy at three institutions between 2020 and 2022 were included in this retrospective multi-center case series. RESULTS At the time of initial COVID-19 infection, all patients developed acute respiratory distress syndrome, and six patients (86%) required ICU admission. Median time intervals from the initial COVID-19 diagnosis to the diagnosis of post-COVID-19 cholangiopathy and liver transplantation were 4 and 12 months, respectively. Four patients underwent living donor liver transplantation, and three patients underwent deceased donor liver transplantation. The median MELD score was 22 (range, 10-38). No significant intraoperative complications were observed. The median ICU and hospital stays were 2.5 and 12.5 days, respectively. One patient died due to respiratory failure 5 months after liver transplantation. Currently, the patient and graft survival rate is 86% at a median follow-up of 11 months. CONCLUSIONS Liver transplantation is a viable option for patients with post-COVID-19 cholangiopathy with acceptable outcome. Timely identification of this disease and appropriate management, including evaluation for liver transplantation, are essential.

Abstract
Liver transplantation (LT) is a potential curative treatment for unresectable colorectal cancer liver metastasis (CRLM). Familial hypercholesterolemia (FH) is an inherited condition characterized by elevated low-density lipoprotein cholesterol (LDL-C) levels. Liver transplantation is offered for selected cases, and an explanted liver can be used as a domino graft. We report the first report of domino LT for unresectable CRLM using a liver from a patient with heterozygous FH. The domino donor was a 30-year-old female with a history of heterozygous FH. She had failed medical therapies for FH, including plasmapheresis; therefore, she underwent living donor LT as a treatment for FH. The explanted liver was transplanted to the domino recipient. She has been doing well with normal LDL-C levels. The domino recipient was a 44-year-old female with a history of stage 4 sigmoid cancer with liver metastases, for which she underwent laparoscopic sigmoid colectomy and right hepatectomy. She developed unresectable lesions in the remnant left lobe, which were controlled well with chemotherapy; therefore, she underwent domino LT. She is doing well without recurrence at the 31-month follow-up. Domino LT from a donor with heterozygous FH is feasible for strictly selected patients with unresectable CRLM.

Abstract
Objective Robotic-assisted live donor nephrectomy (LDN) is being gradually adopted across transplant centers. The left donor kidney is preferred over right due to anatomical factors and ease of procurement. We aimed to study donor and recipient outcomes after robotic procurement and subsequent open implantation of right and left kidneys. Methods All fully robotic LDNs and their corresponding open kidney transplants performed at our center between February 2016 and December 2021 were retrospectively analyzed. Results Out of 196 robotic LDN (49 [right] vs. 147 [left]), 10 (5.1%) donors had intra-operative events (6.1% [right] vs. 4.8% [left], p=0.71). None of the LDN required conversion to open surgery. The operative times were comparable for the two groups. Nausea (13.3%) was the most common post-operative complication. There was no mortality in either LDN group. Herein, we report our outcomes on 156 recipients (39 right and 117 left allografts) excluding robotic implants, exports, and pediatric recipients. There were no significant differences between right and left kidney recipients with respect to 1-year post-transplant patient survival (100.0% vs. 98.1%, p=0.45) or graft survival (93.9% vs. 97.1%, p=0.11), or delayed graft function (7.7% vs. 5.1%, p=0.55). Conclusion Non-hand-assisted robotic live donor nephrectomies can be safely performed with excellent outcomes. Right LDN was not associated with higher incidence of complications compared to left LDN. Open implantation of robotically procured right renal allografts was not associated with higher risk of recipient complications.

Abstract
Building a precise alternative neurotoxicological test is of great importance to respond to societal and ethical requirements. In this study, a new developmental neurotoxicity test (DNT) was established with the human neural progenitor cell line. ReNcell CX cells were exposed to neurotoxic chemicals (aphidicolin, hydroxyurea, cytosine arabinoside, 5-fluorouracil, and ochratoxin A) or non-neurotoxic chemicals (sodium gluconate, sodium bicarbonate, penicillin G, and saccharin). Propidium iodide (PI) was used to evaluate cell viability. BrdU and Ki-76 were employed to determine cell proliferation. Based on the cell viability and proliferation, mathematical models were built by linear discriminant analysis. Furthermore, the neurotoxic-considered chemicals inhibited cell cycle progression at the protein level, supporting the biomolecular rationale for the predictive model. Overall, these results show that the new test method can be used to determine the potential developmental neurotoxicants or new drug candidates.

Abstract
Efficacy of cleaning methods against SARS-CoV-2 suspended in either 5% soil load (SARS-soil) or simulated saliva (SARS-SS) was evaluated immediately (hydrated virus, T0) or 2 hours post-contamination (dried virus, T2). Hard water dampened wiping (DW) of surfaces, resulted in 1.77-3.91 log reduction (T0) or 0.93-2.41 log reduction (T2). Incorporating surface pre-wetting by spraying with a detergent solution (D + DW) or hard water (W + DW) just prior to dampened wiping did not unilaterally increase efficacy against infectious SARS-CoV-2, however, the effect was nuanced with respect to surface, viral matrix, and time. Cleaning efficacy on porous surfaces (seat fabric, SF) was low. W + DW on stainless steel (SS) was as effective as D + DW for all conditions except SARS-soil at T2 on SS. DW was the only method that consistently resulted in > 3-log reduction of hydrated (T0) SARS-CoV-2 on SS and ABS plastic. These results suggest that wiping with a hard water dampened wipe can reduce infectious virus on hard non-porous surfaces. Pre-wetting surfaces with surfactants did not significantly increase efficacy for the conditions tested. Surface material, presence or absence of pre-wetting, and time post-contamination affect efficacy of cleaning methods.

Abstract
BACKGROUND Traditionally, simultaneous liver kidney transplantation (SLK) has been performed using a subcostal incision for the liver allograft and a lower abdominal incision for kidney transplantation (dual incision, DI). At our institution, we performed SLK using a single subcostal incision (SI). The aim of this study was to report the outcomes of single versus dual incisions for SLK. METHODS A retrospective cohort study of consecutive SLK procedures performed at our center from January 2015 to April 2021 was performed. The demographic characteristics, complications, intraoperative findings, and complications after SI and DI were statistically compared. RESULTS A total 37 SLK were performed (19 DI and 18 SI). The age and indications for transplantation were comparable between the two groups. Patient in SI group had significantly higher MELD score (27.0 ± 1.5 vs. 31.7 ± 1.5, p = .038). The cold ischemic time of kidney transplantation (599 ± 26 min vs. 447 ± 27 min, p < .001) and the total surgical time (508 ± 21 min vs. 423 ± 22 min, p = .008) were significantly shorter in the SI group. The incidence of complications and post-transplant kidney function was comparable between the groups. A slightly higher incidence of surgical site complications was noted in the DI group without any statistically significance (p = .178). CONCLUSIONS Single-subcostal incision SLK is technically feasible and has comparable outcomes to dual-incision SLK. SI was associated with shorter cold ischemic time for kidney transplant, as well as shorter overall operative time.

Abstract
AIMS This study evaluated the residual efficacy of commercially available antimicrobial coatings or films against SARS-CoV-2 on nonporous surfaces. METHOD AND RESULTS Products were applied to stainless steel or ABS plastic coupons and dried overnight. Coupons were inoculated with SARS-CoV-2 in the presence of 5% soil load. Recovered infectious SARS-CoV-2 was quantified by TCID50 assay. Tested product efficacies ranged from <1.0 to >3.0 log10 reduction at a 2-hour contact time. The log10 reduction in recovered infectious SARS-CoV-2 ranged from 0.44 to 3 log10 reduction on stainless steel and 0.25 to >1.67 log10 on ABS plastic. The most effective products tested contained varying concentrations (0.5 to 1.3%) of the same active ingredient: 3- (trihydroxysilyl) propyldimethyloctadecyl ammonium chloride. Products formulated with other quaternary ammonium compounds were less effective against SARS-CoV-2 in this test. CONCLUSIONS The residual antimicrobial products tested showed varied effectiveness against SARS-CoV-2 as a function of product tested. Several products were identified as efficacious against SARS-CoV-2 on both stainless steel and ABS plastic surfaces under the conditions evaluated. Differences in observed efficacy may be due to variation in active ingredient formulation; efficacy is, therefore, difficult to predict based upon listed active ingredient and its concentration. SIGNIFICANCE AND IMPACT This study highlights formulation-specific efficacy of several products against SARS-CoV-2 and may inform future development of residual antiviral products for use on nonporous surfaces. The identification of antimicrobial coatings or films showing promise to inactivate SARS-CoV-2 suggests that these products may be worth future testing and consideration.

Abstract
Quiescent human hepatic stellate cells (HSCs) serve as important reservoirs of fat-soluble vitamins in the body, namely vitamin A. In an activated form, HSCs are the drivers of fibrosis following chronic liver injury. In non-alcoholic steatohepatitis (NASH) specifically, activated HSCs are drivers of induction and progression of fibrogenesis. Isolation and purification of HSCs from donor liver samples provides an avenue to study HSCs and their fibrotic capabilities. Manual and chemical digestion of donor liver via dissection and Pronase, collagenase, and DNAse treatment creates a suspension of non-parenchymal liver cells. Quiescent HSCs can be further isolated from this suspension by density-gradient centrifugation in a 6%, 8%, 12%, and 15% arabinogalactan medium. After collection of HSCs from the low-density layers of the gradient, they can be grown on uncoated plastic. Rodent HSCs can also be isolated via density-gradient centrifugation. To isolate activated HSCs, liver tissue explants or established immortalized HSC lines can be utilized. Here, we described protocols for isolation of human and rodent HSCs.

Abstract
BACKGROUND Many centres deny obese patients with a body mass index (BMI) >35 access to kidney transplantation due to increased intraoperative and postoperative complications. METHODS From August 2017 to December 2019, 73 consecutive cases of kidney transplantation in morbidly obese patients were enrolled at a single university at the initiation of a robotic transplant surgery program. Outcomes of patients who underwent robotic assisted kidney transplant (RAKT) were compared to frequency-matched patients undergoing open kidney transplant (OKT). RESULTS A total of 24 morbidly obese patients successfully underwent RAKT, and 49 obese patients received an OKT. The RAKT group developed fewer surgical site infections (SSI) than the OKT group. Graft function, creatinine, and glomerular filtration rate (GFR) were similar between groups 1 year after surgery. Graft and patient survival were 100% for both groups. CONCLUSIONS RAKT offers a safe alternative for morbidly obese patients, who may otherwise be denied access to OKT.

Abstract
Background: Trauma victims with liver lacerations in the hilum are typically excluded from liver donation. We report a case of a successful liver transplant from a deceased donor with a grade 4 hilar liver laceration.
Case Presentation: We used a liver with a high-grade laceration from a 28-year-old brain-dead traffic accident victim. The liver had grade IV lacerations in the right and caudate lobes. In situ split liver technique was applied to control the lacerations after an intraoperative cholangiogram revealed favourable anatomy. The left hemi-liver graft was procured, retaining the entire vena cava and the full length of the main hepatic vasculature. The recipient was a 62-year-old female patient with end-stage liver disease, with a Model for End-Stage Liver Disease-Sodium score of 19. The left lobe graft was transplanted using the standard piggy-back technique. The patient was discharged on postoperative day 7 after an uneventful recovery. At two-month follow-up, she continues to do well, with normal hepatic function and unremarkable imaging studies.
Conclusion: This is the first reported case of a successful liver transplant of a severely lacerated liver made possible by the application of split liver techniques. In situ splitting of a severely traumatized liver could permit the utilization of a reduced graft for small recipients.

Abstract
OBJECTIVE This retrospective study investigated the nature and severity of venom-induced consumption coagulopathy (VICC) and determined the clotting factors involved in VICC in patients after envenomation by South Korea's snakes. Additionally, we studied the effectiveness of antivenom for the treatment of VICC after envenomation. METHODS Included patients were divided into three groups according to the severity of VICC (no VICC, partial VICC, and complete VICC). Data, including changes in coagulation parameters during hospitalization and clotting factors at presentation, were collected and analyzed. RESULTS One hundred nineteen patients who presented at our emergency department within 3 h after snake envenomation were included. VICC developed in 34 patients (27 patients with partial VICC and 7 patients with complete VICC). Two of 34 patients with VICC required blood transfusions. Five patients with complete VICC had an undetectable fibrinogen concentration at presentation. Three patients with complete VICC had an unmeasurable INR and aPTT within 24 h. The median times of the most extreme values were 10 h for INR, 12 h for aPTT, and 16 h for fibrinogen after presentation in the VICC group. The D-dimer concentration peaked at a median of 63.5 h after presentation. The activities of factors II and X were significantly reduced in the complete VICC group (factor II: 88 (84-99.3)% in the non-VICC group vs. 69 (49.5-83.5)% in the complete VICC group; factor X:94 (83-102) in the non-VICC group vs. 70 (66.5-79.8)% in the complete VICC group), while there was no difference in factor V activity at presentation. The time from bite to first antivenom administration did not correlate with the time course and most extreme concentrations for fibrinogen and D-dimer within the VICC groups. DISCUSSION AND CONCLUSION VICC occurs in approximately one-quarter of snakebite patients in South Korea; however, VICC itself does not appear to lead to clinical deterioration. Fibrinogen is an early diagnostic maker for complete VICC. Clotting factors II and X are involved in VICC. Future investigations should explore the mechanism of VICC from Korean snakebites and the effect of antivenom on VICC.

Abstract
OBJECTIVE To examine the concordance rate of non-chromosomal congenital malformations in twin pairs based on zygosity. DESIGN Retrospective cohort study. SETTING A tertiary hospital in Korea. POPULATION Twin pairs born at Seoul National University Hospital between 2001 and 2019. METHODS Congenital malformations were diagnosed by postnatal workups of neonates or autopsy in cases of stillborn infants. Zygosity was confirmed by sex, chorionicity and DNA analysis. MAIN OUTCOME MEASURES Concordance rate of congenital malformations in twin pairs based on zygosity. RESULTS In total, 3386 twin pairs were included. The risk of a congenital malformation in the index twin increased significantly if the co-twin had the congenital malformation, and the concordance rate was higher in monozygotic (MZ) than in dizygotic (DZ) twins (37.04 versus 16.77, P < 0.001). An increased risk of a congenital malformation in the presence of the same congenital malformation in the co-twin was observed only for malformations of the nervous system, eye/ear/face/neck, circulatory system, cleft lip/palate, genital organs, urinary system and musculoskeletal system. Significantly higher concordance rates in MZ than in DZ twin pairs were observed only for the nervous system (40.00 versus 0.00, P < 0.001), circulatory system (32.97 versus 19.74, P = 0.021), cleft lip/palate (44.44 versus 0.00, P = 0.017) and urinary system (22.22 versus 0.00, P = 0.004), whereas significant differences were not found for the genital organs or musculoskeletal system. CONCLUSIONS Monozygotic twins had higher concordance rates than DZ twins only in specific organ systems. It may be speculated that nervous system, circulatory system, cleft lip/palate and urinary system are primarily genetically affected. TWEETABLE ABSTRACT Monozygotic twins had higher concordance rates than dizygotic twins only in specific organ systems.

Abstract
CONTENT This study investigated the incidence, progression and clinical course of myocardial injury-related snake envenomation in South Korea. In addition, this study evaluated whether antivenom guidelines are appropriate to control envenomation in patients with myocardial injury. METHODS The study included 198 patients who received antivenom after a snakebite, and they were divided into two groups according to evidence of myocardial injury (defined as elevated troponin I or ischemic change on electrocardiogram) at presentation. Data including serial troponin I, echocardiogram/coronary angiogram findings, the clinical course, and treatment were collected and analyzed. RESULTS The incidence of myocardial injury at presentation was 15.2%. The troponin I level was 0.11 (0.07-0.56) ng/ml at presentation and tended to decrease over 24 h. Echocardiograms revealed neither regional wall motion abnormalities nor left ventricular dysfunction in 15 of 17 patients, while two patients showed signs of coronary artery stenosis on echocardiograms and coronary angiograms. However, compared with patients without myocardial injury, patients with myocardial injury had a higher frequency of systemic envenomation complications, including bleeding, respiratory failure, hypotension, acute kidney injury, thrombocytopenia and venom-induced consumption coagulopathy (VICC). The patients with myocardial injury at presentation needed significantly more frequent and larger doses of antivenom than indicated by the initial severity of envenomation. Multivariate analysis showed that myocardial injury was associated with the need for additional antivenom administration after initial administration. DISCUSSION AND CONCLUSION Myocardial injury is not uncommon after snake envenomation in Korea. Although myocardial injury itself seems to be benign, the clinical course of patients with myocardial injury is complicated, and myocardial injury is associated with the need for additional antivenom administration. The optimal use of antivenom to control envenomation in patents with myocardial injury after snake envenomation in South Korea should be established.

Abstract
The embryoid body test (EBT) is a developmental toxicity test method that measures the size of embryoid bodies (EBs) and the viability of mouse embryonic stem cells (mESCs) and fibroblasts (3T3 cells). The previous pre-validation study confirmed the high accuracy (above 80%) of EBT using 26 coded test chemicals. This second-phase validation study assessed the inter-laboratory reproducibility (5 chemicals in common) and predictive capacity (10 chemicals in each laboratory) test using the coded test chemicals at three laboratories. For the prediction model, the accuracy is increased when more data is accumulated. Therefore, we updated the prediction model and analyzed the results of the second year with the newly created-prediction model. Statistical analysis of the inter-laboratory reproducibility test results indicated that accuracy, sensitivity, and specificity were 87%, 78%, and 100%, respectively. The results of the statistical analysis of the predictive capacity test showed an accuracy of 80%, sensitivity of 78%, and specificity of 81%. In conclusion, the EBT can accurately classify various embryotoxicants within a short period and with relatively little effort. Therefore, EBT can be used as a good way to test developmental toxicity.

Abstract
Several previous studies have reported that physical activity (PA) levels can independently affect the prevalence of gallstone disease (GD) in Western countries. However, this association has not been reported in Eastern countries. Therefore, this study aimed to determine whether PA is an independent determinant of GD prevalence in a Korean population, according to the World Health Organizations Global Recommendations on PA for Health.A total of 8908 subjects who completed a questionnaire underwent medical examination and ultrasound scanning at the Health Promotion Center of the Jeju National University Hospital between January 2009 and December 2018. GD and fatty liver disease were diagnosed by abdominal ultrasound. Biochemical parameters and body mass index were determined, and metabolic syndrome status, age, and PA levels were extracted from medical records. Univariate and multivariate analyses were performed to identify independent factors affecting GD.The estimated rates of PA and GD among male subjects were 23.7% and 4.6%, whereas the rates among females were 18.4% and 4.2%, respectively. Multivariate analysis suggested that no PA, old age, and higher aspartate aminotransferase level in males and nonalcoholic fatty liver disease status in females were independent factors affecting GD.In our study, PA was associated with a reduction in GD among males but not females.

Abstract
BACKGROUND This study aimed to determine the prognostic significance of radiographic sarcopenia (RS) in patients with gallbladder cancer (GBC). METHODS From March 2001 to December 2013, 158 GBC patients who underwent curative intent surgery were included. The presence of RS was determined by skeletal muscle mass index using abdominal computed tomography. RESULTS The 1-, 3-, and 5-year overall survival (OS) rates were 63.6%, 41.9%, and 36.4%, respectively, for patients with RS (n = 88), and 84.3%, 62.6%, and 54.3%, respectively, for those without RS (n = 70) (P = 0.006). Multivariate analysis showed that RS (hazard rate [HR] 1.704, P = 0.024) was a significant prognostic factor for patient survival, as well as disease stage (IV: HR 7.181, P < 0.001), radicality (HR 2.830, P = 0.001), adjuvant therapy (HR 0.537, P = 0.017), and intraoperative blood loss ≥ 1 L (HR 1.851, P = 0.023). CONCLUSIONS This study showed a significant association between RS and OS in GBC patients. Because RS is the only significant prognostic factor that can be evaluated preoperatively, its assessment would be helpful to provide early preventive therapy allowing the maintenance of muscle mass and patient-tailored treatment based on their physiologic reserves (e.g., skeletal muscle mass).

Abstract
BACKGROUND We aimed to assess the nutritional status of cancer patients according to site or treatment type. METHODS We prospectively evaluated the nutritional status of 1,588 patients based on cancer site and treatment type using the Patient-Generated Subjective Global Assessment tool. We also investigated length of stay (LOS), complication rates after surgery and quality of life (QoL). RESULTS The patients with esophageal, pancreaticobiliary, and lung cancer had higher malnutrition rates than those with stomach, liver, and colon cancer (52.9%, 47.6%, and 42.8% vs. 29.1%, 24.7%, and 15.9%, respectively; P < 0.05). Patients undergoing chemoradiotherapy (CRT) or supportive care had higher malnutrition rates than those undergoing surgery (35.2% or 68.6% vs. 12.3%; P < 0.05). Among patients undergoing surgery, malnourished patients had longer LOS and tended to have more complications than well-nourished patients (P < 0.05 and P = 0.146, respectively). Malnourished patients had also poorer QoL than well-nourished patients (P < 0.05). CONCLUSION Malnutrition complicated more in patients with esophageal, pancreaticobiliary, or lung cancer than in those with stomach, liver, or colon cancer. Patients undergoing CRT or supportive care are more likely to be malnourished than those undergoing surgery. Malnutrition may increase LOS and impair QoL.

Abstract
This study investigated whether hyperthermia within the first 24 h after presentation was associated with long-term neurological outcomes after acute carbon monoxide (CO) poisoning. This retrospective study included 200 patients with acute severe CO poisoning. Hyperthermia (≥ 37.5°C) developed during the first 24 h after presentation in 55 (27.5%) patients, and poor long-term neurological sequelae assessed at 23 months after acute CO poisoning developed in 19.5% of the patients. The incidence of poor long-term neurological outcomes was significantly higher in the hyperthermia group than in the normothermia group. Patients with poor long-term neurological outcomes had higher maximum temperatures than patients with good outcomes. No significant difference was found in the time of hyperthermia onset within the first day according to the neurological outcomes. Hyperthermia (adjusted odds ratio (aOR) 5.009 (95% confidence interval (CI) 1.556-16.126)) and maximum temperature (aOR 2.581 (95% CI 1.098-6.063)) within the first 24 h after presentation to the emergency department were independently associated with poor long-term neurological outcomes. Body temperature measurements, which are easily and noninvasively recorded at the bedside in any facility, help to predict the risk for poor long-term neurological outcomes. This study carefully emphasizes fastidious control of pyrexia, particularly during the early period after acute CO poisoning.

Abstract
Backgrounds/Aims Colorectal cancer is found with liver metastases about 20-25% due to characteristics of cancer itself. Approximately 20% of liver metastases are found to be resectable. The objective of this study was to evaluate short-term outcomes of patients who received liver resection with colorectal cancer operation in our center by laparoscopic surgery or open surgery. Methods Short-term outcomes of laparoscopic surgery of liver resection (LSLR) group who underwent liver resection for colorectal liver metastases (CRLM) at a single institute from 2013 to 2016 were compared to those of open surgery of liver resection (OSLR) group. Results A total of 123 patients underwent liver resection for CRLM, including 101 (82.1%) patients in the OSLR group and 22 (17.9%) patients in the LSLR group. There were significant differences in tumor characteristics between the two groups, including synchronous and metachronous (p=0.004), tumor number (p<0.001), and tumor margin (p=0.002). For postoperative outcomes, only the length of hospital stay (LOS) was significantly different between the two groups (8.5 days in LSLR vs. 11 days in OSLR, p<0.001). There was no significant difference in overall rate of postoperative complications between the two groups (9.1% in LSLR vs. 23.8% in OSLR, p=0.158). Conclusions There are no significant differences in postoperative outcomes between LSLR and OSLR except LOS, liver metastasis number, and resection margin. LSLR may be favorable for highly selected patients with CRLM.

Abstract
BACKGROUND New biomarkers are essential for improving the prediction of the survival and prognosis of patients with hepatocellular carcinoma (HCC). Alpha-fetoprotein (AFP) is the most widely used biomarker, but the low sensitivity and specificity limit its clinical applications. The diagnostic and prognostic capabilities of osteopontin (OPN), dickkopf-related protein 1 (DKK1), and a combination of these biomarkers are being studied. METHODS From January 2006 to December 2008, patients undergoing hepatectomy for HCC were screened and their serum stored in tumor banks was analyzed. The serum was used to investigate OPN and DKK1 levels by enzyme-linked immunosorbent assay(ELISA). In the paraffin block, the status of OPN and DKK1 positivity was assessed using immunohistochemistry(IHC). RESULTS A total of 60 patients were enrolled. The optimal cut-off level for survival was identified as 3.0 ng/mL and 5.2 ng/mL of OPN and DKK1, respectively. In multivariate analysis, a high OPN level was the only significant prognostic factor for overall survival [hazard ratio3.79, p = .017]. Considering a combination of AFP (cut-off level, 200 ng/mL) and OPN/DKK1, the patients with high AFP and OPN/DKK1 levels showed significantly lower overall survivals than those with low AFP, high AFP, and low OPN/DKK1 levels (p = .0091 for the AFP and OPN group, p = .0344 for the AFP and DKK1 group). Comparison between IHC and ELISA results for OPN and DKK1 levels did not reveal any significant correlation. CONCLUSIONS Serum OPN and DKK1 levels of HCC patients could be considered as novel biomarkers showing prognostic significance after hepatectomy based on long-term survival data.

Abstract
Diabetes mellitus (DM) is prevalent in patients with pancreatic cancer and tends to improve after tumor resection. However, the glycemic response of non-pancreatic cancer patients after surgery has not been examined in detail. We aimed to investigate the changes in glucose metabolism in patients with pancreatic cancer or non-pancreatic cancer after pancreatoduodenectomy (PD).We prospectively enrolled 48 patients with pancreatic cancer and 56 patients with non-pancreatic cancer, who underwent PD. Glucose metabolism was assessed with fasting glucose, glycated hemoglobin (HbA1c), plasma C-peptide and insulin, quantitative insulin check index (QUICKI), and a homeostatic model assessment of insulin resistance (HOMA-IR) and β cell (HOMA-β) before surgery and 6 months after surgery. Patients were divided into 2 groups: "improved" and "worsened" postoperative glycemic response, according to the changes in HbA1c and anti-diabetic medication. New-onset DM was defined as diagnosis of DM ≤ 2 years before PD, and cases with DM diagnosis >2 years preceding PD were described as long-standing DM.After PD, insulin resistance (IR), as measured by insulin, HOMA-IR and QUICKI, improved significantly, although C-peptide and HOMA-β decreased. At 6 months after PD, new-onset DM patients showed improved glycemic control in both pancreatic cancer patients (75%) and non-pancreatic cancer patients (63%). Multivariate analysis showed that long-standing DM was a significant predictor for worsening glucose control (odds ratio = 4.01, P = .017).Favorable glycemic control was frequently observed in both pancreatic cancer and non-pancreatic cancer after PD. PD seems to contribute improved glucose control through the decreased IR. New-onset DM showed better glycemic control than long-standing DM.

Abstract
Hepatopancreatoduodenectomy (HPD) is usually indicated for the resection of locally advanced bile duct (BD) cancer or gallbladder (GB) cancer. Previous studies have demonstrated a favorable survival rate in BD cancer patients after HPD if R0 resection is achieved. By contrast, the benefit of HPD for GB cancer remains controversial. This study aimed to analyze the outcomes of GB and BD cancer after HPD. Between January 2004 and December 2013, a total of 22 patients underwent HPD for BD (n = 14) or GB cancer (n = 8). We analyzed the survival, mortality, morbidity, and prognostic factors. After HPD, the mortality rate was 4.5 per cent and the morbidity rate was 68.2 per cent. Pancreatic fistula occurred in 50.0 per cent of the patients (grade A, 40.9%; grade B, 9.1%). Liver failure did not occur. The 1-, 3-, and 5-year survival rates for BD cancer patients were 57.1, 17.9, and 17.9 per cent and those for GB cancer patients were 62.5, 25.0, and 25.0 per cent, respectively ( P = 0.768). In BD cancer, significant prognostic factors were tumor size, portal vein invasion, multiple lymph node metastases, and operation time. Furthermore, BD cancer patients with three or more of risk factors showed poorer survival than those with fewer than three risk factors. HPD for GB and BD cancer can be performed with acceptable mortality and morbidity rates. GB cancer patients who underwent HPD showed comparable survival rates compared with BD cancer patients. Long-term survival can be achieved in selected patients with BD cancer.

Abstract
BACKGROUND AND AIM In most patients with perihilar cholangiocarcinoma (PHCC), major hepatectomy and extrahepatic bile duct resection are needed for surgical radicality, and a high risk of hepatic insufficiency exists. This study aims to develop a prediction model for post-hepatectomy liver failure (PHLF) in patients with PHCC. METHODS A total of 143 patients who underwent major liver resection and extrahepatic bile duct resection for PHCC between October 2001 and December 2013 were included. Clinically relevant PHLF was defined as liver failure corresponding to grade B or C of the International Study Group of Liver Surgery criteria. Multivariate logistic regression was used to develop the PHLF risk model. Model performance was evaluated internally using the area under the curve analysis (discrimination) after 1000 bootstrap resampling and the Hosmer-Lemeshow goodness-of-fit test (calibration). RESULTS Post-hepatectomy liver failure occurred in 43.4% of patients (n = 62). In multivariate analysis, PHLF was significantly associated with future liver remnant ratio (odds ratio [OR] per 10% = 0.68, 95% confidence interval [CI] 0.51-0.88), intraoperative blood loss (OR per 1 L = 1.82, 95% CI 1.11-3.17), and preoperative prothrombin time > 1.20 (OR = 3.22, 95% CI 1.15-9.97). The PHLF risk score model showed good discrimination (area under the curve = 0.708, 95% CI 0.623-0.793) and calibration (P = 0.227). CONCLUSIONS The risk model proposed in this study accurately predicted PHLF in patients with PHCC. This offers surgeons a practical guide to quantitative risk assessment of hepatic insufficiency and aids decision-making in surgical treatment and perioperative management.

Abstract
OBJECTIVE This study aimed to investigate whether clinical parameters and serum neuron-specific enolase (NSE) levels measured at emergency department (ED) presentation help stratify the risk of acute or delayed persistent severe neurological sequelae after acute carbon monoxide (CO) poisoning induced by charcoal burning. METHODS This retrospective study included 236 patients who suffered from CO poisoning. Demographic information, serum NSE levels measured in the ED, treatment, clinical course, and long-term neurological outcomes were recorded. RESULTS The median serum NSE level at presentation was 15.5 (10.9-22.7) ng/mL. No differences were observed in the duration of CO exposure; the initial Glasgow Coma Scale (GCS) score; the levels of arterial HCO3-, white blood cells (WBCs), C-reactive protein (CRP) or troponin I; or the frequency of abnormal diffusion-weighted imaging finding at presentation among the groups with different serum NSE levels at presentation. The incidences of acute and delayed persistent neurologic sequelae assessed at 22.3 months after acute charcoal CO poisoning were 5.1% and 8.5%, respectively. No difference in the NSE level was observed between patients stratified according to long-term neurological status. According to the multinomial logistic regression analysis, age, serum CRP levels and the initial GCS score were risk factors for the two types of persistent severe neurological sequelae, whereas troponin I levels were associated only with the acute persistent severe neurological sequelae. However, the adjusted NSE level was not a risk factor for any persistent neurological sequelae. CONCLUSIONS Serum NSE levels at presentation were not correlated with the risk of acute or delayed persistent neurological sequelae. Further studies with blood sampling at optimal time points and serial measurements should be conducted. Age, initial GCS score, and CRP levels may be risk factors for persistent severe neurological sequelae.

Abstract
We designed the study to clarify the prognostic significance of perioperative (preoperative, intraoperative, and postoperative) red blood cell (RBC) transfusion following pancreaticoduodenectomy (PD) for periampullary cancers.This study retrospectively analyzed 244 periampullary cancer patients (pancreatic cancer, 124 patients; bile duct cancer, 63 patients; and ampullary cancer, 57 patients) treated by PD from June 2001 to June 2010 at the National Cancer Center, Korea (NCC2017-0106).A total of 112 (46%) of 244 patients had received transfusion (preoperative, 5%; intraoperative, 17%; and postoperative, 37%). The 5-year survival rate of patients without perioperative transfusion was 36%, whereas that of patients with a transfusion was 25% (P = .04). Perioperative transfusion and intraoperative transfusion were found to be independent poor prognostic factors [relative risk (RR): 1.52 and 1.95, respectively]. The independent factors associated with perioperative transfusion were being female, operation time >420 minutes, portal vein (PV) resection, and preoperative serum hemoglobin (Hb) < 12 mg/dL. As the amount of perioperative transfusion increased, overall survival (OS) decreased.Perioperative transfusion, especially intraoperative transfusion was an independent prognostic factor for survival after PD. Therefore, for patients with periampullary cancer, intraoperative bleeding and operation time should be minimized and preoperative anemia corrected.

Abstract
Purpose Even though the therapeutic gold standard of hilar cholangiocarcinoma (HCCA) resection is cancer-free resection margin (RM), surgical treatment still remains challenging. This study evaluated the prognostic significance of RM status in resected HCCA patients and identified survival prognostic factors. Materials and Methods We reviewed records of 96 HCCA patients who underwent surgery from 2001 to 2012 and analyzed the RM status and prognostic factors that affecting survival. Results Negative RM (n=31, 33%) was significantly associated with better survival vs. positive RM (n=65, 67%) (mean survival time [MST], 33 months vs. 21 months; p=0.011). Margins with histological findings of non-dysplastic epithelium, low-grade dysplasia, and carcinoma in situ were not associated with survival differences (MST, 33 months vs. 33 months vs. 30 months; p=0.452), whereas positive margins were associated with poorer survival relative to carcinoma in situ (MST, 30 months vs. 21 months; p=0.050). Among patients with R0 resection, narrow (≤ 5 mm) and wide (> 5 mm) margins were not associated with survival differences (MST, 33 months vs. 30 months; p=0.234). Although positive proximal RM was associated with poorer survival compared to negative RM (MST, 19 vs. 33; p=0.002), no survival difference was observed between positive and negative distal RMs (MST, 30 vs. 33; p=0.628). Proximal RM positivity (hazard ratio [HR], 2.688; p=0.007) and nodal involvement (HR, 3.293; p < 0.001) were independent survival prognostic factors. Conclusion A clear RM, especially proximal RM status, was significant prognosticator, and proximal bile duct resection to the greatest technically feasible extent may be necessary, with careful consideration of the potential morbidity and oncologic outcomes after resection. However, an aggressive approach to obtain a negative distal RM might be controversial and should be considered carefully, depending on the patient's status.

Abstract
PURPOSE This study investigated the predictive factors for progression from seizure-related endosulfan poisoning to status epilepticus (SE) and refractory SE (RSE). This study also investigated delayed neurologic sequelae in seizure-related endosulfan poisoning. METHODS This retrospective, observational case series consisted of 73 patients who developed at least one seizure after endosulfan ingestion. RESULTS The progression rates from seizure-related endosulfan poisoning to SE and from SE-related endosulfan poisoning to RSE were 78.1% and 54.4%, respectively. The SE and RSE fatality rates were 19.2% and 41.9%, respectively. No patients reported the development of delayed neurological sequelae at least six months after discharge. Glasgow coma scale (GCS) score were identified as an independent factor for progression from seizure-related endosulfan poisoning to SE and from SE-related endosulfan poisoning to RSE. Lorazepam administration was independently associated with preventing progression from SE-related endosulfan poisoning to RSE. CONCLUSION Seizure-related endosulfan poisoning had higher progression rates to SE and RSE and higher fatality rates than other drug-induced seizures. However, delayed neurologic sequelae after discharge were not demonstrated. Due to the high progression rates from seizure-related endosulfan poisoning to SE and RSE and the absence of an established treatment for SE-related endosulfan poisoning, physicians should aggressively treat patients who experience a seizure after endosulfan poisoning and who present with decreased GCS score. Lorazepam should be considered a first-line anti-epileptic drug for controlling seizures in patients with endosulfan poisoning.

Abstract
Abstract
The new biomarkers are essential for improving the survival and prognosis of hepatocellular carcinoma(HCC) patients. Alpha-fetoprotein(AFP) is the most widely used biomarker. But the low sensitivity and specificity limits its clinical application. Recent study validated the diagnostic capability of osteopontin(OPN) and dickkopf-1(DKK1) and assessed the combination of AFP, DKK1, and OPN as a panel for the diagnosis of HCC. Based on these previous studies, we hypothesized that combination of OPN and DKK1 can be used to as a marker for prognosis to patient of HCC after hepatectomy. From January 2006 to December 2008, patients undergoing hepatectomy for hepatocellular carcinoma were screened serum that has been stored in the Bank of tumor. To target the selected patient, it was confirmed that the remaining tissue specimen is stored after diagnosis. Serum of the patients was used to investigate the OPN and DKK1 by ELISA. In the paraffin block were prepared unstained slide and OPN and DKK1 level checked by IHC. It examined the correlation between prognosis and biomarkers through statistical analysis. AFP, OPN(serum level) and DKK1(serum level) are an independent prognostic factor for overall survival(OS) in HCC after hepatectomy(n=60, P=0.0204, 0.0167 and 0.0455 respectively). New biomarkers combinations based on the AFP existing biomarker are showed a falling curve of the overall survival(OS) and disease-free survival(DFS) in Kaplan Meier curve. In conclusion, combination of OPN, DKK1 and AFP as a biomarker could support the correct diagnosis for HCC after hepatectomy.

Abstract
BACKGROUND AND AIM The improvements in surgical technique and perioperative management in the recent decades may warrant revisit for survival outcomes and prognostic factors after liver resection for hepatocellular carcinoma (HCC). This study aimed to analyze the survival outcomes after liver resection for HCC for a consecutive cohort of 1002 patients. METHODS This study was performed by analyzing the clinicopathological and follow-up data of 1002 consecutive patients who underwent liver resection for HCC from April 2001 to December 2013. Prognostic factors were investigated by univariate and multivariate analysis, using the Cox's proportional hazards model. RESULTS The overall incidence of postoperative complications was 16.1% (n = 161), with an in-hospital mortality rate of 0.3% (n = 3). The rates of 1-, 3-, and 5-year overall survival were 91.9%, 78.9%, and 69.5%, while the rates of 1-, 3-, and 5-year recurrence-free survival were 71.7%, 51.7%, and 43.7%, respectively. Multivariate analysis showed that patient age, platelet count, intraoperative estimated blood loss (EBL), tumor number, Edmond-Steiner grade, microvascular invasion, major vessel invasion, and intrahepatic metastasis were independent significant prognostic factors affecting the overall survival. Platelet count, intraoperative EBL, maximal tumor size, major vessel invasion, capsule formation, intrahepatic metastasis, cirrhosis, and the pathological stage were independent prognostic factors for recurrence-free survival. CONCLUSIONS Survival of patients with HCC after resection should be stratified by various perioperative clinicopathological factors. Platelet count and intraoperative EBL could be considered as one of the powerful predictors of the prognosis and recurrence of HCC in such patients.

Abstract
The importance of bile duct division cannot be overemphasized in living donor surgery. Ligation and cut (LC) as a method for bile duct division in living donor right hepatectomy (LDRH) has never been reported. The purpose of this study was to introduce the LC method of bile duct division in LDRH. All LDRH donors were identified through a prospectively maintained database at the authors' institution between September 2009 and March 2013, and the 2 methods, LC and cut and oversewing (CO), were compared both in terms of donor and recipient outcomes of right lobe living donor liver transplantation. In the LC method, after complete parenchymal transection, the right hepatic duct was dissected in the Glisson's sheath and ligated just at the right side of the confluence, and then the right side of the ligature was cut. The LC and CO methods were performed in 109 and 134 donors, respectively. Bile duct division time (P < 0.001) and operative time (P < 0.001) were significantly shorter in the LC group than in the CO group. With a median follow-up of 60.2 months, biliary complication rate was lower in the LC group than in the CO group (0% versus 5.2%; P = 0.01), but with no significant difference between the recipient groups. All donors made a complete recovery. In conclusion, the bile ducts of living donors can be dissected safely from the Glisson's sheath, and the LC method facilitates bile duct division and has a lower incidence of biliary complication in LDRH without compromising the recipient outcomes.

Abstract
Portal vein embolization (PVE) is increasingly performed worldwide to reduce the possibility of liver failure after extended hepatectomy, by inducing future liver remnant (FLR) hypertrophy and atrophy of the liver planned for resection. The procedure is known to be very safe and to have few procedure-related complications.In this study, we described 2 elderly patients with Bismuth-Corlette type IV Klatskin tumor who underwent right trisectional PVE involving the embolization of the right portal vein, the left medial sectional portal branch, and caudate portal vein. Within 1 week after PVE, patients went into sepsis combined with bile leak and died within 1 month.Sepsis can cause acute liver failure in patients with chronic liver disease. In this study, the common patient characteristics other than sepsis, that is, trisectional PVE; chronic alcoholism; aged >65 years; heart-related comorbidity; and elevated serum total bilirubin (TB) level (7.0 mg/dL) at the time of the PVE procedure in 1 patient, and concurrent biliary procedure, that is, percutaneous transhepatic biliary drainage in the other patient might have affected the outcomes of PVE.These cases highlight that PVE is not a safe procedure. Care should be taken to minimize the occurrence of infectious events because sepsis following PVE can cause acute liver failure. Additionally, prior to performing PVE, the extent of PVE, chronic alcohol consumption, age, comorbidity, long-lasting jaundice, concurrent biliary procedure, etc. should be considered for patient safety.

Abstract
BACKGROUND Few studies have evaluated the impact of previous abdominal surgery (PAS) on living donor right hepatectomy (LDRH). The aim of this study was to investigate the outcomes of liver transplantation using right lobe grafts of living donors with PAS. METHODS Data were reviewed from LDRH patients at the authors' institution between March 2008 and November 2014. LDRH patients with PAS were divided into two groups according to upper PAS (group 1) or lower PAS (group 2), and they were compared to those without PAS (group 3) who were matched 1:1 based on age, gender, and body mass index. Perioperative data, complications by the Clavien classification, and the outcomes with more than 14 months follow-up were compared. RESULTS Twenty-three (4.9%) of a total of 471 LDRH donors had PAS. Eleven donors were assigned to group 1, 12 to group 2, and 23 to group 3. Intraperitoneal adhesions were found in 20 (87.0%) of 23 donors with PAS, of whom 5 (21.7%) had adhesiolysis-related injuries that happened more commonly in group 1 than in group 2 (P=0.025). LDRH was successfully completed under upper midline laparotomy in all donors. No donors received perioperative blood transfusion. The peak postoperative AST, ALT, INR, and total bilirubin levels made no difference between the three groups. Compared with group 3, groups 1 and 2 had a longer operative time (P=0.012) and a higher grade I complication rate (P=0.047). All donors recovered fully to their routine activities. The 23 recipients of grafts from donors with PAS showed good liver function with 1-year graft and patient survivals of 100%. CONCLUSION A history of PAS is not a contraindication to LDRH in the current era of advanced surgical techniques.

Abstract
Abstract
Background
Skin antiseptic agents are used to prevent surgical-site infection (SSI); few trials have reported the superiority of any specific agent in clean-contaminated abdominal surgery. This RCT was designed to compare the effectiveness of chlorhexidine gluconate and povidone–iodine.
Methods
Consecutive patients who underwent clean-contaminated upper gastrointestinal or hepatobiliary–pancreatic open surgery between 2011 and 2014 were assigned randomly to either chlorhexidine gluconate or povidone–iodine. The primary endpoint was the occurrence of SSI within 30 days of surgery. Secondary endpoints included causative organisms and risk factors for SSI.
Results
A total of 534 patients were randomized; 31 (5·8 per cent) developed an SSI. There was no difference in the overall SSI rate in the chlorhexidine gluconate and povidone–iodine groups: 15 of 267 (5·6 per cent) and 16 of 267 (6·0 per cent) respectively (P = 0·853). The most common causative organism was Enterococcus faecalis. In subgroup analysis, biliary–pancreatic surgery had a higher SSI rate (26 of 127, 20·5 per cent) than upper gastrointestinal (2 of 204, 1·0 per cent) and hepatic (3 of 203, 1·5 per cent) resection. Both age (60 years and over) and type of incision were associated with the risk of SSI.
Conclusion
No difference was detected between chlorhexidine gluconate and povidone–iodine antiseptics for prevention of SSI. Registration number: NCT01495117 (http://www.clinicaltrials.gov).

Abstract
Living donor liver transplantation (LDLT) becomes an important option for treatment for patients with hepatocellular carcinoma (HCC). With the advance of imaging modalities such as computed tomography (CT) and magnetic resonance image (MRI), preoperative staging and diagnosis for HCC was improved in LDLT. However, morphological characteristics based on the tumor number and size do not represent the tumor pathology and prognosis clearly. Therefore, many criteria using various markers have been reported, but still have limitation to predict the pathology and prognosis. Recently, 18F-fluorodeoxyglucose-positron emission tomography/CT (18F-FDG PET/CT) was introduced to have the usefulness for detection of extrahepatic metastases and prediction of post-transplant prognosis in liver transplantation (LT). Furthermore, the hybrid concept with both biologic activity using PET/CT and morphologic tumor characteristics using CT and MRI was reported to be selection criteria for the patient with HCC waiting LDLT. We will discuss the role of 18F-FDG PET/CT in LDLT as various aspects including tumor detection, pathology prediction, prognosis prediction, and possibility of selecting criteria.

Abstract
We describe 2 cases of patients with loss of hepatic arterial flow during surgery for pancreatic head cancer due to celiac stenosis caused by median arcuate ligament compression. The first case underwent pylorus-resecting pancreatoduodenectomy for pancreatic head cancer. After resection of the gastroduodenal artery, flow in the common hepatic artery disappeared, and celiac axis stenosis was identified. Interventional stent insertion was attempted, however, it failed due to the acute angle of the celiac orifice (os). This problem was resolved by arterial reconstruction. The second case underwent pylorus-preserving pancreatoduodenectomy for pancreatic head cancer and the same phenomenon occurred during the procedure. Interventional stent insertion was also tried; in this patient, however, it failed due to the acute angle of the celiac os. The problem was resolved by changing a femoral approach to a brachial approach, and the stent was inserted into the celiac os successfully.

Abstract
Chronic obstructive lung disease (COPD) primarily affects men; however, its epidemiology has been changing because more women have become smokers. Recently, investigators found that although women and men were exposed to the same amount of smoke fume, women tended to have more severe disease and higher mortality rate. They also complain of more dyspnoea and may experience more severe exacerbations than men. This led to the question of whether sex has an impact on COPD course and whether women have a higher susceptibility to smoke fumes than men. That may be explained by multiple complex factors highlighting the relationship between sex, epidemiology, method of diagnostics and the clinical course of the disease. In this review, sex differences in epidemiology, clinical presentation, exacerbation, co-morbidities and treatment are covered.

Abstract
AIM: To expand the living donor liver transplantation (LT) pool of eligible patients with hepatocellular carcinoma (HCC) using new morphological and biological criteria.
METHODS: Patients with HCC who underwent living donor LT (LDLT) from March 2005 to May 2013 at the National Cancer Center Korea (NCCK) were enrolled. We performed the 18F-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) before LDLT. Overall and disease-free survival analysis was done in patients to evaluate the usefulness of new NCCK criteria using PET/CT and total tumor size (10 cm).
RESULTS: We enrolled a total of 280 patients who pathologically confirmed to have HCC and performed the PET/CT before transplantation. Among them, 164 (58.6%) patients fulfilled the NCCK criteria and 132 patients (47.1%) met the Milan criteria. Five-year overall and disease-free survival rates for patients who fulfilled the NCCK criteria showed 85.2% and 84.0%, respectively, and were significantly higher than those beyond the NCCK criteria (60.2% and 44.4%, respectively; P < 0.001). The correlation analysis between preoperative imaging tests and pathologic reports using Cohen’s Kappa demonstrated the better results in the NCCK criteria than those in the Milan criteria (0.850 vs 0.583). The comparison of disease-free analysis among the NCCK, Milan, and University of California, San Francisco (UCSF) criteria using the receiver operating characteristics curves revealed the similar area under the curve value criteria (NCCK vs Milan, P = 0.484; NCCK vs UCSF, P = 0.189 at 5-years).
CONCLUSION: The NCCK criteria using hybrid concept of both morphological and biological parameters showed an excellent agreement between preoperative imaging and pathological results, and favorable survival outcomes. These new criteria might select the optimal patients with HCC waiting LDLT and expand the selection pool.

Abstract
The impact of intra-abdominal adhesion (IAA) on living donor right hepatectomy (LDRH) remains to be clarified. The purpose of this study was to compare both the donor and recipient outcomes of right lobe living donor liver transplantation according to IAA detected intraoperatively. LDRH donors were identified through a prospectively maintained database at the authors' institution between March 2008 and February 2014. IAA was graded according to Beck et al (Dis Colon Rectum 2000; 43: 1749-1753). LDRH donors with IAA (group A) were matched 1:3 to those without IAA (group B) based on age, gender, and BMI. Perioperative data, complications by the Clavien classification, and the outcomes with at least 12 months follow-up were compared. Thirty-two (7.6%) of a total of 420 LDRH donors had IAA around the liver. Nineteen donors had previous abdominal surgery. LDRH was successfully completed under upper midline laparotomy in all donors. Compared with group B, group A had a longer operative time (270 vs. 172 min; p < 0.001), a higher wound complication rate (28.1% vs. 4.2%; p = 0.009), and a longer postoperative stay (10 vs. 7 days; p = 0.009). All donors recovered completely to their previous activities. The 1-year graft and recipient survivals of recipients were comparable between two groups. These findings support the feasibility and safety of LDRH in patients with IAA.

Abstract
AIM: To investigate the impact of high-dose hepatitis B immunoglobulin (HBIG) on hepatocellular carcinoma (HCC) and hepatitis B virus (HBV) recurrence and overall survival after living donor liver transplantation (LDLT).
METHODS: We investigated 168 patients who underwent LDLT due to HCC, and who were HBV-DNA/hepatitis B e antigen (HBeAg) -positive, from January 2008 to December 2013. After assessing whether the patients met the Milan criteria, they were assigned to the low-dose HBIG group and high-dose HBIG group. Using the propensity score 1:1 matching method, 38 and 18 pairs were defined as adhering to and not adhering to the Milan criteria. For each pair, HCC recurrence, HBV recurrence and overall survival were analyzed by the Kaplan-Meier method and the log rank test according to the HBIG dose.
RESULTS: Among those who met the Milan criteria, the 6-mo, 1-year, and 3-year HCC recurrence-free survival rates were 88.9%, 83.2%, and 83.2% in the low-dose HBIG group and 97.2%, 97.2%, and 97.2% in the high-dose HBIG group, respectively (P = 0.042). In contrast, among those who did not meet the Milan criteria, HCC recurrence did not differ according to the HBIG dose (P = 0.937). Moreover, HBV recurrence and overall survival did not differ according to the HBIG dose among those who met (P = 0.317 and 0.190, respectively) and did not meet (P = 0.350 and 0.987, respectively) the Milan criteria.
CONCLUSION: High-dose HBIG therapy can reduce HCC recurrence in HBV-DNA/HBeAg-positive patients after LDLT.

Abstract
The concept of surgery for enhanced recovery (SFER) program has never been an issue in the context of living donor right hepatectomy (LDRH), much less its effects. The purpose of this study was to evaluate outcomes after the establishment of an SFER protocol for LDRH in a single center.A single-center cohort study was performed in 500 consecutive living donors who underwent right hepatectomy from January 2005 to June 2014 by analyzing the outcomes before and after an established SFER protocol that evolved with continuous refinements in surgical technique and management over 300 LDRHs, being in place on September 2011. Donor characteristics, operative outcomes, and postoperative complications divided into 2 groups (group 1, stepwise adjustment; group 2, complete adherence to the protocol) were compared.Donor characteristics were comparable in the 2 groups. Overall complication rate was 10.0% with no mortality. In group 2, operative time, hospital stay, and overall complication rate decreased significantly, and the morbidity was 1% and confined in grade I complication without reoperation, perioperative blood transfusion, or readmission. All donors in this series recovered fully and returned to the previous functional lifestyle.An SFER protocol on LDRH can be established by the gradual implementation of various refinements of surgical technique, and the recent outcomes achieved after the establishment of an SFER protocol could provide a current guidance on LDRH toward the ultimate goal of zero morbidity.

Abstract
BACKGROUND Many patients with active Crohn's disease do not adequately respond to therapies, highlighting the need for new treatments. AIMS To conduct a randomised, double-blind, placebo-controlled phase 3 study to assess the efficacy and safety of vercirnon, an oral inhibitor of CC chemokine receptor-9, for the treatment of patients with moderately-to-severely active Crohn's disease. METHODS Patients with a Crohn's Disease Activity Index (CDAI) of 220-450, plus evidence of active disease (endoscopically confirmed or elevation of both C-reactive protein and faecal calprotectin), who had failed corticosteroid or immunosuppressant therapy were enrolled. Patients were equally randomised to receive placebo, vercirnon 500 mg once daily or vercirnon 500 mg twice daily. The primary endpoint was clinical response, defined as a 100-point decrease in CDAI from baseline to week 12. RESULTS Six hundred and eight patients were randomised. Patient characteristics and baseline demographics were similar among the groups. The proportions of patients achieving a clinical response were 25.1%, 27.6% and 27.2% for placebo, once daily and twice daily respectively; treatment differences were not significant (2.5%; 95% confidence interval, CI -6.1% to 11.0%, P = 0.546 for once daily vs. placebo, and 2.1%; 95% CI -6.5% to 10.7%, P = 0.648 for twice daily vs. placebo). Adverse events were reported in 69.8%, 73.3% and 78.1% with serious adverse events in 8.9%, 5.9%, and 6.0% of patients in the placebo, once-daily and twice-daily groups, respectively. CONCLUSIONS We did not demonstrate efficacy of vercirnon as an induction therapy in patients with moderately-to-severely active Crohn's disease; its effect in maintenance therapy was not addressed.

Abstract
BACKGROUND Clinical factors were previously identified as predictors of short-term treatment efficacy in Crohn's disease (CD). The PRECiSE 3 (P3) 7-year trial provides an opportunity to study predictors of short- and long-term clinical remission among CD patients treated with certolizumab pegol (CZP). AIM To identify factors that influence long-term remission of CD with CZP treatment. METHODS Patients who had completed placebo-controlled studies (PRECiSE 1/PRECiSE 2, P1/P2) enrolled in P3 and received open-label CZP 400 mg every 4 weeks up to 7 years. Baseline predictors included, but were not limited to, smoking status, disease duration, prior inflammatory bowel disease (IBD) surgery, Harvey-Bradshaw Index (HBI), albumin, haematocrit and CZP exposure; association with time to initial remission (HBI ≤4) was tested for patients who received CZP in P1/P2; time to loss of remission/frequency of maintenance of remission was also tested. Univariate analyses and multivariate Cox or logistic regression models were used. RESULTS Predictors for initial remission (N = 377) included age, haematocrit, prior IBD surgery and entry HBI (P < 0.05 for all). Predictors for loss of remission (N = 437) included HBI, serum albumin concentration, haematocrit, smoking status and exposure. Predictors of maintenance of remission (N = 437) included haematocrit, IBD surgery, HBI, disease duration, serum albumin concentration and exposure. Significant predictors were confirmed with stepwise multivariate regression models. CONCLUSIONS These analyses identified several influential parameters for short-and long-term remission of Crohn's disease with certolizumab pegol treatment. The data yield valuable hypotheses regarding factors that influence certolizumab pegol treatment. More investigation is needed. (ClinicalTrials.gov identifier NCT00552058).

Abstract
BACKGROUND Leukocyte subsets in peripheral blood, which include neutrophils, lymphocytes, and monocytes, have not been well established as prognostic factors in patients with hepatocellular carcinoma (HCC). METHODS Consecutive patients who underwent curative hepatic resection for HCC at the National Cancer Center, Republic of Korea, from 2001 to 2008 were enrolled in this retrospective study. Clinicopathologic factors, cancer-specific survival (CSS), and disease-free survival (DFS) were analyzed with respect to preoperative lymphocyte subsets, especially monocyte ratio. RESULTS The 603 patients had a median follow-up of 40.0 months and a 5-year overall survival rate of 67.7 %. In univariate analysis of survivals, preoperative lymphocyte ratio ≤35 % and monocyte ratio >7 % were significantly poor prognostic factors. In multivariate analysis, preoperative monocyte ratio >7 %, satellite nodule, and microvascular invasion were independent risk factors for CSS and DFS (hazard ratio of monocyte ratio >7 % = 1.77, p = 0.02 and 1.57, p = 0.006, respectively). Considering monocyte ratio with preoperative α-fetoprotein level, patients with both abnormal α-fetoprotein levels (>12 ng/mL) and monocyte ratio >7 % showed significantly worse CSS and DFS than other groups (p < 0.001). Cirrhotic patients with monocyte ratio >7 % showed significantly poor CSS and DFS compared with non-cirrhotic patients (p = 0.033 and <0.001, respectively). CONCLUSIONS A preoperative monocyte ratio >7 % of peripheral blood is an independent risk factor for CSS and DFS after hepatic resection for HCC. Preoperative monocyte ratio might be considered as a novel biomarker for HCC.
