Hong SY, Kim T, Kim BW. Selection of Safe Donors for Living Donor Liver Transplant Using Extended Right Lobe Graft. Transplant Proc 2023; 55:30-37.

Abstract
Extended right lobectomy (ERL) for living donor liver transplant (LDLT) is selectively performed in many transplant centers and has shown excellent recipient outcomes as reported in previous studies. Yet, there is no universally accepted indication for ERL in respect to donor safety. Current study was designed to stratify risk factors of adverse donor outcome after ERL. A total of 79 living donors who underwent ERL for LDLT were included in analysis. Donors were classified as safety and hazard donor groups according to postoperative findings relevant to posthepatectomy liver failure classification by the International Study Group for Liver Surgery. On multivariable analysis, left lateral section volume <20% of total liver volume and nonpreservation of segment 4a venous drainage were the independent risk factors impairing postoperative outcomes. Despite the short-term impairment of liver function in hazard donor groups, all donors recovered and showed satisfactory remnant liver regeneration. However, these findings have implications in establishing selection criteria of donors eligible for ERL donation. In conclusion, LDLT using ERL graft can be safely performed provided so that left lateral section volume/total donor liver is ≥20% besides conventional donor selection criteria. Also, efforts to preserve segment 4a vein must be made in performing ERL graft procurement in LDLT donors.

Abstract
BACKGROUND In adult right lobe living donor liver transplantation, the decision to include the middle hepatic vein (MHV) remains controversial. METHODS A retrospective analysis of 50 R-LDLTs between January 2008 and June 2016 was performed. RESULTS Twenty-one procedures were performed using a MHV+ graft (42.0%) and 29 procedures using a MHV- graft (58%). MHV- donors were taller (173 vs 166 cm, p = 0.004) with a larger standard liver volume (1351 vs 1245 mls, p = 0.014) compared to MHV+ donors. The duration of operation for donors was significantly longer in the MHV+ group (530 (313-975) mins) compared to the MHV- group (489 (336-708) mins) (p = 0.029). Similarly, the operative time for recipients was longer in the MHV+ group (660 (428-831) mins) compared to MHV- (579 (359-1214) mins) (p = 0.023). MHV- grafts were heavier compared to MHV+ grafts (918 vs 711 g, p = 0.017). Recipient mortality rates and Kaplan-Meier survival analysis were comparable (p = 0.411). All donors were well at last review. CONCLUSION Both MHV+ and MHV- grafts are safe for the donor and recipient. The decision to take the MHV should be based on specific donor-recipient characteristics.

Abstract
OBJECTIVES Hepatic venous congestion is associated with impaired graft regeneration in living-donor liver transplant, and the management of middle hepatic vein tributaries in the right lobe graft represents an unresolved issue. In this study, we aimed to investigate the precise outflow pattern of segments 5 and 8 between the right hepatic vein and middle hepatic vein and the respective regeneration rates after living-donor liver transplant with right lobe graft, as available data on these relevant topics are scarce. MATERIALS AND METHODS We conducted a retrospective analysis of computed tomography scans with 3-dimensional simulation, vessel reconstruction, and volume measurement of 38 right lobe grafts without middle hepatic vein. Follow-up time was 3 months after living-donor liver transplant. RESULTS In donors, segments 5 and 8 measured 141.9 ± 48.8 mL (21.0% of graft volume) and 230.4 ± 52.5 mL (34.3% of graft volume), respectively, with significant difference between volumes (P < .01). Percentage of segmental venous drainage in segment 5 was 55.5 ± 17.2% for the middle hepatic vein and 41.0 ± 20.9% for the right hepatic vein; drainage in segment 8 was 46.4 ± 13.2% for the middle hepatic vein and 52.9 ± 13.2% for the right hepatic vein. The outflow pattern was significantly different between segments for both veins (P = .01 for middle hepatic vein and P < .01 for right hepatic vein), showing that segment 5 was statistically more dependent on the middle hepatic vein and segment 8 was more dependent on the right hepatic vein. For living-donor liver transplant recipients, the prevalence of middle hepatic vein tributary reconstruction was 39.5%. At 3-month follow-up, the regeneration rate for the posterior sector was 85.8 ± 39.9%, whereas rates for segments 5 and 8 were 33.4 ± 39.7% and 68.4 ± 41.0%, respectively (P < .01). CONCLUSIONS In living-donor liver transplant with right lobe graft and without middle hepatic vein, segment 5 is the most vulnerable graft area for impaired regeneration. Segments 5 and 8 should be evaluated independently on the basis of their respective outflow patterns to more precisely plan the outflow management and patient outcomes.

Abstract
AIM To investigate the efficacy of surgery combined with post-operative trancatheter arterial chemoembolization (TACE) for intermediate hepatocellular carcinoma (HCC). METHODS A total of 102 patients were divided into two groups: Radical liver resection only (LR group, 52 patients) and radical liver resection combined with post-operative TACE (combined group, 50 patients). Survival analysis was performed using the Kaplan-Meier method. Univariate and multivariate analysis were performed using Cox proportional analysis to detect prognostic factors of survival outcomes. RESULTS The 1-, 3- and 5-year survival rate in the LR group were significantly lower compared with those in combined group (p = .019). The 1-, 3- and 5-year progression-free survival rate in the LR group were also lower than those in the combined group (p = .048). Multivariate analysis detected that tumor number (multiple vs single), tumor distribution (both lobes vs semi-liver), treatment strategy (surgery + TACE vs surgery) were independent factors for OS (HR values were 2.307, 3.155 and 0.526, respectively) and PFS (HR values were 1.938, 3.425 and 0.633, respectively; p < .05). CONCLUSION In conclusion, surgery combined with post-operative TACE may improve survival outcomes for patients with intermediate HCC. Tumor number, tumor distribution and treatment strategy (surgery + TACE) were significantly associated with the prognosis of patients with intermediate HCC.

Abstract
Brain death is a rare situation after living-donor liver transplantation. However, the recipient who suffers from brain death and has functional liver graft is a potential liver donor. We report the 1st case of successful reuse of extended right living-donor liver graft after brain death of the first recipient. The first recipient, who had acute liver failure caused by hepatitis A virus, experienced brain death on the 2nd day after the transplantation. The allograft had a favorable regeneration and functional recovery. On the 7th day, the allograft was procured with a patent hepatic artery, bile duct, portal vein, and reconstructed outflow (right hepatic vein and middle hepatic vein) and successfully implanted into the second recipient. The second recipient has experienced a long-term survival without any complications.

Abstract
The objective of the present study was to investigate the association between zinc finger protein (ZNF) 689 expression and the clinicopathological features and prognosis of hepatocellular carcinoma (HCC). A total of 102 paired HCC and paired non-cancerous tissues, and 16 normal liver tissues were collected. ZNF689 expression was examined in HCC tissues, paired-noncancerous tissues, and normal liver tissues using RT-qPCR and immunohistochemistry analysis, and the association between ZNF689 expression and HCC prognosis was analyzed using the Kaplan-Meier method. ZNF689 expression was not significantly different between HCC tissues and paired-noncancerous tissues (P=0.61). ZNF689 expression in HCC and paired-noncancerous tissues was significantly increased compared with that in normal liver tissues (P<0.01). Positive expression of ZNF689 protein in HCC was significantly associated with a tumor size of ≥10 cm, tumor capsule infiltration, and microvascular invasion (P<0.05). Positive expression of ZNF689 was a prognostic factor for overall survival time [hazard ratio (HR):1.961; P=0.048] and progression-free survival time (HR:1.902; P=0.041). ZNF689 maybe a novel predictor for prognosis of patients with HCC.

Abstract
MicroRNA (miR)-21 has been identified as a novel biomarker of hepatocellular carcinoma (HCC). However, the prognostic value of miR-21 expression in HCC remains controversial. The aim of the present study was to investigate the value of high expression of miR-21 in predicting the prognosis of HCC. Following a search through the PubMed, Science Citation Index, EMBASE and CNKI databases, a total of 9 studies investigating the expression of miR-21 in HCC and the association between high expression of miR-21 and prognosis of HCC were identified. It was observed that high expression of miR-21 was not associated with poor overall survival of all patients with HCC (P=0.52). However, high expression of miR-21 was found to be correlated with poor prognosis of HCC patients undergoing curative resection (hazard ratio = 2.36; P<0.01). It was also demonstrated that high expression of miR-21 was correlated with tumor size >5 cm [odds ratio (OR)=1.53; P=0.04], venous invasion (OR=4.86; P=0.01), TNM stage (OR=3.44; P<0.01) and liver cirrhosis (OR=2.12; P=0.03). It was concluded that miR-21 cannot be considered as a factor complementary to α-fetoprotein, microvascular invasion and advanced tumor stage in predicting the prognosis of all HCC patients. Higher expression of miR-21 may be a promising biomarker associated with certain clinicopathological characteristics of HCC, such as tumor size, venous invasion, TNM stage and liver cirrhosis.

Abstract
This meta-analysis aimed to comprehensively assess the efficacy and safety of hepatic resection combined with radiofrequency ablation versus hepatic resection (HR) alone for the treatment of multifocal hepatocellular carcinomas (HCC). A literature search was conducted from the database including MEDLINE, Embase, Cochrane Central Register of Controlled Trials (CENTRAL) and China Biology Medicine (CBM) disc. The primary outcomes included the 1-, 3-, 5-year overall survival (OS) and disease-free survival (DFS) rate. The secondary outcomes contained the intraoperative parameters and postoperative adverse events (AEs). These parameters were all analyzed by RevMan 5.3 software. After carefully screening relevant studies, four retrospective studies of high quality involving 466 patients (197 in the combined group and 269 in the HR group) were included in this study. The pooled results showed that the 1-, 3-, 5-year OS rate in the combined group were comparable with those in the HR group (OR=0.77, 0.96, 0.88; P=0.33, 0.88, 0.70, respectively). Similarly, there was no significant difference in 1-, 3-, 5-year DFS rate between the combined group and the HR alone group (OR=0.57, 0.83, 0.72; P=0.17, 0.37, 0.32, respectively). And the intraoperative parameters and postoperative AEs were also comparable between the above two cohorts. However, two included studies reported that tumor often recurred in the ablation site in the combined group. The present meta-analysis indicated that the HR combined with RFA could reach a long-term survival outcome similar to curative HR for multifocal HCC patients. And this therapy may be a promising alternative for these patients with marginal liver function or complicated tumor distribution. Furthermore, high quality randomized controlled trials (RCTs) are imperative to verify this conclusion.

Abstract
Pleural effusion after hepatectomy is associated with significant morbidity and prolonged hospital stays. Several studies have addressed the risk factors for postoperative pleural effusion. However, there are no researches concerning the role of the initial 12-h operative fluid volume. The aim of this study was to evaluate whether the initial 12-h operative fluid volume during liver resection is an independent risk factor for pleural effusion after hepatectomy. In this study, we retrospectively analyzed clinical data of 470 patients consecutively undergoing elective hepatectomy between January 2011 and December 2012. We prospectively collected and retrospectively analyzed baseline and clinical data, including preoperative, intraoperative, and postoperative variables. Univariate and multivariate analyses were carried out to identify whether the initial 12-h operative fluid volume was an independent risk factor for pleural effusion after hepatectomy. The multivariate analysis identified 2 independent risk factors for pleural effusion: operative time [odds ratio (OR)=10.2] and initial 12-h operative fluid volume (OR=1.0003). Threshold effect analyses revealed that the initial 12 h operative fluid volume was positively correlated with the incidence of pleural effusion when the initial 12-h operative fluid volume exceeded 4636 mL. We conclude that the initial 12-h operative fluid volume during liver resection and operative time are independent risk factors for pleural effusion after hepatectomy. Perioperative intravenous fluids should be restricted properly.
