Abstract
BACKGROUND The consensus that portal venous pressure modulation, including splenectomy (Spx), prevents portal hypertension-related complications after living-donor liver transplantation (LDLT) has been established. However, little evidence about the risk factors for graft loss after simultaneous Spx during LDLT is available. This study aimed to identify the independent predictors of graft loss after simultaneous Spx during LDLT. METHODS Data of 655 recipients who underwent LDLT between 1997 and 2021 were collected and separated into the simultaneous Spx group (n = 461) and no-Spx group (n = 194). RESULTS The simultaneous Spx group had significantly lower serum total bilirubin levels, drained ascites volumes, and prothrombin time-international normalized ratios on postoperative day 14 than the no-Spx group ( P < 0.001 for each). Incidences of small-for-size graft syndrome ( P < 0.001), acute cellular rejection ( P = 0.002), and sepsis ( P = 0.007) were significantly lower in the Spx group. Graft survival of the Spx group was significantly better than that of the no-Spx group ( P < 0.001; hazard ratio [HR], 1.788; 95% confidence interval, 1.214-2.431). A multivariate analysis revealed that 3 variables, platelet count ≤4.0 × 10 4 /mm 3 ( P = 0.029; HR, 2.873), donor age ≥60 y old ( P = 0.013; HR, 6.693), and portal venous pressure at closure ≥20 mm Hg ( P = 0.010; HR, 3.891), were independent predictors of graft loss within 6 mo after simultaneous Spx during LDLT. CONCLUSIONS Spx is a safe inflow modulation procedure with a positive impact on both postoperative complications and prognosis for most patients. However, patients with the 3 aforementioned independent factors could experience graft loss after LDLT.

What is the crux of successful living-donor liver transplantation for recipients aged 70 and beyond? Ann Gastroenterol Surg 2024; 8:668-680. [PMID: 38957553 PMCID: PMC11216780 DOI: 10.1002/ags3.12769] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/28/2023] [Revised: 11/27/2023] [Accepted: 12/24/2023] [Indexed: 07/04/2024] Open
Abstract
Aim There is limited evidence regarding the feasibility of living-donor liver transplantation (LDLT) for patients aged over 70. The aims of this study were to assess postoperative outcomes in elderly recipients and to ascertain the potential feasibility and acceptability of LDLT. Methods Data were collected from 762 recipients, including 26 in the elderly group (aged ≥70) and 736 in the younger group (aged <70), and reviewed even by propensity score matching (PSM). Results No significant differences were observed in the frequency of postoperative complications between the two groups. Additionally, both groups exhibited a comparable 30-day mortality rate after LDLT (3.9% in both) and similar hospital stays (36 days vs. 40 days). The 1-, 3-, and 5-year graft survival rates in the elderly group were 92.0%, which was comparable to those in the younger group (p = 0.517), as confirmed by PSM. Notably, all donors for elderly patients were the children of the recipients, with an average age of 41.6 years, and grafts from donors aged ≥50 years were not utilized, signifying the use of high-quality grafts. Our inclusion criterion for elderly recipients was strictly defined as an ECOG-PS score of 0-2, which played a pivotal role in achieving favorable postoperative outcomes. Conclusion LDLT can be performed safely for elderly patients aged 70 years or older, provided they have a preserved PS and receive high-quality grafts from younger donors, inevitably all children of elderly recipients. This approach yields acceptable long-term outcomes. Consequently, age alone should not serve as an absolute contraindication for LDLT.

A successful case of deceased-donor liver transplantation from a donor with Marfan syndrome: a case report. Surg Case Rep 2024; 10:14.

Abstract
BACKGROUND Liver transplantation is the definitive therapy for patients with decompensated cirrhosis. Marfan syndrome is a systemic inheritable connective tissue disease associated with fibrillin-1 gene mutations, which cause abnormalities in connective tissue. Vascular changes due to Marfan syndrome occur mostly in the main vessels due to the high amount of connective tissue within the vessel wall and the high pressure and blood flow to which they are exposed. The incidence of changes in visceral arteries is about 0.42% and usually presents with cystic medial necrosis. This report is the first deceased-donor liver transplantation with a donor with Marfan syndrome with a history of abdominal surgery. CASE PRESENTATION A patient in his 50s underwent liver transplantation for decompensated alcoholic cirrhosis. The donor, a 50s male with Marfan syndrome, was diagnosed with brain-death due to a cerebral hemorrhage caused by a cerebral aneurysm. The donor's clinical presentation as Marfan syndrome was aortic dissection, with multiple surgical procedures performed from the aortic root to the abdominal aorta. An intraoperative biopsy of the hepatic artery showed no abnormality, so this organ was considered appropriate. The surgery was completed without any problems of the arterial anastomosis. The patient's postoperative course was uneventful, and he was transferred to a hospital for recuperation on the 18th postoperative day. One year after the surgery, the patient is still alive without any complications from the transplantation or arterial problems. CONCLUSIONS Even if the patient had a history of surgery for vascular anomalies extending to the abdominal aorta due to Marfan syndrome, the patient can be a donor for liver transplantation under appropriate judgment, including intraoperative biopsy.

Abstract
The right posterior section (RPS) graft for living donor liver transplantation is an alternative graft in a live liver donor with insufficient remnant left lobe volume and portal vein anomaly. Although there have been some reports regarding pure laparoscopic donor right posterior sectionectomy (PLDRPS), no study has compared PLDRPS versus pure laparoscopic donor right hemihepatectomy (PLDRH). The aim of our study was to compare the surgical outcomes of PLDRPS versus PLDRH at centers achieving a complete transition from open to laparoscopic approach in liver donor surgery. From March 2019 to March 2022, a total of 351 living donor liver transplantations, including 16 and 335 donors who underwent PLDRPS and PLDRH, respectively, were included in the study. In the donor cohort, there were no significant differences in major complication (≥grade III) rate and comprehensive complication index between the PLDRPS versus PLDRH group (6.3% vs. 4.8%; p = 0.556 and 2.7 ± 8.6 vs.1.7 ± 6.4; p = 0.553). In the recipient cohort, there was a significant difference in major complication (≥grade III) rate (62.5% vs. 35.2%; p = 0.034) but no significant difference in comprehensive complication index (18.3 ± 14.9 vs. 15.2 ± 24.9; p = 0.623) between the PLDRPS and PLDRH groups. PLDRPS in live liver donors with portal vein anomaly and insufficient left lobe was technically feasible and safe with experienced surgeons. The PLDRPS group might be comparable with the PLDRH group based on the surgical outcomes of donors and recipients. However, in terms of recipient outcomes, more careful selection of donors of the RPS graft and further research in a large number of cases are necessary to evaluate the usefulness of PLDRPS.

Abstract
PURPOSE Unusual grafts, including extended left liver plus caudate lobe, right anterior section, and right posterior section grafts, are alternatives to left and right lobe grafts for living-donor liver transplantation. This study aimed to investigate unusual grafts from the perspectives of recipients and donors. METHODS From 2016 to 2021, 497 patients received living-donor liver transplantation at Severance Hospital. Among them, 10 patients received unusual grafts. Three patients received extended left liver plus caudate lobe grafts, two patients received right anterior section grafts, and five patients received right posterior section grafts. Liver volumetrics and anatomy were analyzed for all recipients and donors. We collected data on laboratory examinations (alanine aminotransferase, total bilirubin, international normalized ratio), imaging studies, graft survival, and complications. A 1:2 ratio propensity-score matching method was used to reduce selection bias and balance variables between the unusual and conventional graft groups. RESULTS The median of Model for End-stage Liver Disease score of unusual graft recipients was 13.5 (interquartile range 11.5-19.3) and that of graft-recipient weight ratio was 0.767 (0.7-0.9). ABO incompatibility was observed in four cases. The alanine aminotransferase level, total bilirubin level, and international normalized ratio decreased in both recipients and donors. Unusual and conventional grafts had similar survival rates (p = 0.492). The right and left subgroups did not differ from each counter-conventional subgroup (p = 0.339 and p = 0.695, respectively). The incidence of major complications was not significantly different between unusual and conventional graft recipients (p = 0.513). Wound seromas were reported by unusual graft donors; the complication ratio was similar to that in conventional graft donors (p = 0.169). CONCLUSION Although unusual grafts require a complex indication, they may show feasible surgical outcomes for recipients with an acceptable donor complication.

Abstract
The recipient muscle status is closely associated with postoperative poor survival in recipients of living donor liver transplantation (LDLT). However, it is uncertain whether LDLT donor muscle quality and quantity affect graft quality. Hence, we analyzed the correlation between donor muscle status and graft function. We measured the skeletal muscle mass index (SMI) and intramuscular adipose tissue content (IMAC) of 380 LDLT donors. We examined the correlation between donor SMI or IMAC and graft mortality, the occurrence rates of small-for-size graft (SFSG) syndrome, and 6-month graft survival rates. The donor SMI had no effect on the occurrence of SFSG syndrome and graft survival, while a high IMAC in both male and female donors was significantly correlated with the rate of SFSG syndrome [high vs low: (male donors) 15.8% vs. 2.5%, p = 0.0003; (female donors) 12.8% vs. 3.1%, p = 0.0234] and 6-month graft survival rates [(male donors) 87.7% vs 95.9%, p = 0.02; (female donors) 83.0% vs. 99.0%, p < 0.0001]. Multivariate analysis revealed that a high donor IMAC (HR; 5.42, CI; 2.13-13.8, p = 0.0004) was an independent risk factor for 6-month graft survival, and the donor IMAC is useful for donor selection for high-risk recipients.

Abstract
The quality and size of liver grafts are critical factors that influence living‐donor liver transplantation (LDLT) function and safety. However, the biomarkers used for predicting graft quality are lacking. In this study, we sought to identify unique graft quality markers, aside from donor age, by using the livers of non‐human primates. Hepatic gene microarray expression data from young and elderly cynomolgus macaques revealed a total of 271 genes with significantly increased expression in the elderly. These candidate genes were then narrowed down to six through bioinformatics analyses. The expression patterns of these candidate genes in human donor liver tissues were subsequently examined. Importantly, we found that grafts exhibiting up‐regulated expression of these six candidate genes were associated with an increased incidence of liver graft failure. Multivariable analysis further revealed that up‐regulated expression of LRRN2 (encoding leucine‐rich repeat protein, neuronal 2) in donor liver tissue served as an independent risk factor for graft failure (odds ratio 4.50, confidence interval 2.08–9.72). Stratification based on graft expression of LRRN2 and donor age was also significantly associated with 6‐month graft survival rates. Conclusion: Up‐regulated LRRN2 expression of liver graft is significantly correlated with graft failure in LDLT. In addition, combination of graft LRRN2 expression and donor age may represent a promising marker for predicting LDLT graft quality.

[PMID: 34092213 PMCID: PMC8183075 DOI: 10.1186/s12876-021-01835-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/06/2021] [Accepted: 05/28/2021] [Indexed: 11/19/2022] Open
Abstract
Background The right posterior segment (RPS) graft was introduced to overcome graft size discrepancy in living donor liver transplantation (LDLT). However, it was very rarely used in pediatric patients. Here we presented 4 pediatric LDLT cases receiving RPS graft between January 2015 and April 2020 in our center. A total of 1868 LDLT procedures were performed in this period. Methods Recipients included 1 boy and 3 girls with a median age of 45 months (range from 40 to 93 months). They were diagnosed with progressive familial intrahepatic cholestasis, propionic academia, ornithine transcarbamylase and biliary atresia, respectively. Four donors were all mothers with a median age of 32.5 years (31–38 years). Computer tomography angiography indicated posterior right branches branched off separately from main portal veins (type III variation). Three of these donor livers had 1 orifice of right hepatic veins (RHV). In the remaining 1 donor liver, the RHV showed 3 orifices and an outflow patch plastic was performed. Inferior right hepatic veins weren’t found in four donor grafts. The median graft weight was 397.5 g (352–461 g) and the median graft-to-recipient weight ratio was 2.38% (1.44–2.80%). Results Postoperative complications occurred in neither donors nor recipients. Within the median follow-up duration of 29 months (14–64 months), four children are all alive with normal liver function. Conclusion In summary, for older children weighed more than 15 kg with donors’ variation of type III portal veins, the use of RPS grafts could be a feasible and favorable option.

Immunosuppression Free Protocol for Liver Transplant from an Identical Twin Mimicking Positive Donor-Specific Antibodies: A Case Report. Transplant Proc 2021; 53:2576-2579. [PMID: 34001347 DOI: 10.1016/j.transproceed.2021.04.008] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2021] [Revised: 03/11/2021] [Accepted: 04/05/2021] [Indexed: 12/14/2022]
Abstract
There are some reported cases of liver transplant between identical twins with no immunosuppressants because of their matched HLA. However, there is no mention of donor-specific antibodies (DSA). Here, we report a rare case of living donor liver transplant (LDLT) between identical twins, mimicking DSA positivity, on a low-dose immunosuppression protocol. A 57-year-old man with acute liver failure underwent LDLT using the right lobe from his identical twin. Their blood types were identical on HLA matching. However, the preoperative DSA test results were positive for class II antibodies. This was supposed to be due to the relatively large amount of blood transfusion before testing: a total of 580 units of fresh frozen plasma for plasma exchange. The presence of class II antibodies for DSA positivity was the result of the passive immunity from transfusion, and this result could not be ignored, given the risk of rejection. Therefore, we arranged low-dose postoperative immunosuppressants using tacrolimus at a quarter dose and no mycophenolate mofetil. The postoperative course was uneventful. A few months after LDLT, the patient's DSA level was negative for class II antibodies, thus confirming our preoperative hypothesis of DSA as the result of transfusion. Currently, 6 months after LDLT, he is free from immunosuppressive medication with good liver function. When administering relatively large doses of fresh frozen plasma by repeated plasma exchange before LDLT, even between identical twins, it is important to consider that the DSA test could be positive and that immunosuppressive treatment should be performed carefully.

Which is better to use "body weight" or "standard liver weight", for predicting small-for-size graft syndrome after living donor liver transplantation? Ann Gastroenterol Surg 2021; 5:363-372. [PMID: 34095727 PMCID: PMC8164458 DOI: 10.1002/ags3.12412] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/17/2020] [Revised: 11/08/2020] [Accepted: 11/10/2020] [Indexed: 12/13/2022] Open
Abstract
AIM Little evidence about whether to apply graft-to-recipient body weight ratio (GRWR) or graft weight to standard liver weight (GW/SLW) for graft selection has been published. The aim of the present study was to clarify the importance of the correct use of GRWR and GW/SLW for selecting graft according to the recipients' physique in living donor liver transplantation (LDLT). METHODS Data were collected for 694 recipients who underwent LDLT between 1997 and 2020. RESULTS One of the marginal grafts meeting GW/SLW ≥ 35% but GRWR < 0.7% has been used in more recipients with men and higher body mass index (BMI), and the other meeting GRWR ≥ 0.7% but GW/SLW < 35% has been used in more recipients with women with lower BMI. In the cohort of BMI > 30 kg/m2, the recipients with GRWR < 0.7% had a significantly higher incidence of small-for-size graft syndrome (SFSS) compared to those with GRWR ≥ 0.7% (P = 0.008, 46.2% vs 5.9%), and using the cutoff of GW/SLW < 35% could not differentiate. In contrast, in the cohort of BMI ≤ 30 kg/m2, the recipients with GW/SLW < 35% also had a significantly higher incidence of SFSS (P = 0.013, 16.9% vs 9.4%). Multivariate analysis showed that GRWR < 0.7% [odds ratio (OR) 14.145, P = 0.048] was the independent risk factor for SFSS in obese recipients, and GW/SLW < 35% [OR 2.685, P = 0.002] was the independent risk factor in non-obese recipients. CONCLUSION Proper use of the formulas for calculating GRWR and GW/SLW in choosing graft according to recipient BMI is important, not only to meet metabolic demand for avoiding SFSS but also to ameliorate donor shortages.

Simultaneous splenectomy improves outcomes after adult living donor liver transplantation. J Hepatol 2021; 74:372-379. [PMID: 32827564 DOI: 10.1016/j.jhep.2020.08.017] [Citation(s) in RCA: 26] [Impact Index Per Article: 8.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/11/2018] [Revised: 07/28/2020] [Accepted: 08/12/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS Small-for-size graft (SFSG) syndrome is a major cause of graft loss after living donor liver transplantation (LDLT). Splenectomy (Spx) is an option to prevent this catastrophic complication, but its effect remains controversial. Herein, we aimed to elucidate the effect of simultaneous Spx on graft function and long-term outcomes after LDLT. METHODS Three hundred and twenty patients were divided into 2 groups: those undergoing (n = 258) and those not undergoing (n = 62) simultaneous Spx. To overcome selection bias, propensity score matching (PSM) was performed (n = 50 in each group). RESULTS Before PSM, recipients undergoing simultaneous Spx showed better graft function on post-operative day (POD) 7 and 14, as well as lower sepsis frequency within 6 months after LDLT and better graft survival rates compared to those not undergoing Spx. After PSM, compared to patients not undergoing Spx, those undergoing Spx had a lower frequency of early graft dysfunction on POD 7 (p = 0.04); a lower frequency of SFSG syndrome (p = 0.01), lower serum total bilirubin levels (p = 0.001), and lower international normalized ratio (p = 0.004) on POD 14; lower sepsis frequency within 6 months after LDLT (p = 0.02), and better graft survival rates (p = 0.04). Univariate analysis revealed that not undergoing Spx (hazard ratio 3.06; 95% CI 1.07-11.0; p = 0.037) was the only risk factor for graft loss after LDLT. CONCLUSIONS Simultaneous Spx may prevent SFSG syndrome and is a predictive factor for graft survival after LDLT. Simultaneous Spx is recommended when a small graft (≤35% of standard liver weight) is predicted preoperatively, or for patients with portal hypertension or high portal pressure (above 20 mmHg) after reperfusion in LDLT. LAY SUMMARY Living donor liver transplantation (LDLT) for patients with acute or chronic liver failure is an alternative to overcome the deceased donor shortage. The potential mismatch between graft and body size is a problem that needs to be solved for LDLT recipients. Herein, we evaluated the impact of simultaneous splenectomy and showed that it was associated with favorable outcomes in patients undergoing LDLT.

Predictor of outcome after living donor liver transplantation for patients with hepatocellular carcinoma beyond the Japan criteria. Ann Gastroenterol Surg 2020; 4:413-421. [PMID: 32724885 PMCID: PMC7382431 DOI: 10.1002/ags3.12335] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/12/2020] [Revised: 03/11/2020] [Accepted: 03/20/2020] [Indexed: 12/21/2022] Open
Abstract
BACKGROUND The Japan criteria (JC, maximum tumor size within 5 cm, within five tumor nodules, AFP within 500 ng/mL or within Milan criteria) have been applied to cadaveric liver transplantation (LT) for hepatocellular carcinoma (HCC) and will be used for living donor LT (LDLT) in Japan. The aim of this study was to verify the JC in LDLT and to clarify the risk factor of HCC recurrence and mortality after LDLT beyond the JC. PATIENTS AND METHODS Adult patients who underwent LDLT for end-stage liver disease with HCC until October 2019 were reviewed retrospectively (n = 246). Patients were divided into two groups according to whether they were within JC (n = 203) or beyond JC (n = 43). Recurrence-free or overall survival rates after LDLT were compared. Univariate and multivariate analyses were performed to identify risk factors of HCC recurrence and HCC-related mortality after LDLT for patients beyond the JC. RESULTS Patients beyond the JC had significantly poorer 5-year recurrence-free (50.3% vs 95.9%, P < .001) or overall (61.7% vs 98.1%, P < .001) survival rates compared with patients within the JC. A multivariate analysis revealed that des-gamma-carboxy prothrombin (DCP) ≥ 300 mAU/mL (hazard ratio 9.36, 95% CI; 2.41-36.4, P = .001) was an independent risk factor for HCC recurrence and HCC-related mortality (hazard ratio 13.8, 95% CI; 1.92-98.6, P = .01) after LDLT in patients beyond the JC. CONCLUSION The outcome of LDLT for patients within the JC was favorable. Patients beyond the JC with DCP ≥ 300 mAU/mL might be contraindicated for LDLT.

Biliary Complications After Single- and Dual-Graft Living-Donor Liver Transplantation Using a Right Posterior Section Graft of Donor with a Type III Portal Vein Variation. Transplant Proc 2020; 52:1838-1843. [PMID: 32444130 DOI: 10.1016/j.transproceed.2020.01.142] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2019] [Accepted: 01/10/2020] [Indexed: 01/10/2023]
Abstract
BACKGROUND When the donor's left lobe volume is <30%, donor selection for the right posterior section graft (RPSG) is based on the type III portal vein (PV) anatomic variation. Herein, we validated the selection of a donor with a type III PV variation for RPSG to prevent biliary complications (BCs) after single-graft (SG) and dual-graft (DG) living-donor liver transplantation (LDLT). METHODS The clinical data of recipients and donors with a type III PV variation for LDLT using an RPSG performed between January 2004 and June 2018 were retrospectively collected and analyzed to determine the occurrence of BCs. RESULTS The 26 LDLTs performed using an RPSG, including 20 DG LDLT cases, accounted for 0.6% of all LDLT cases (n=4292). BCs developed in 6 recipients (23.0%), including biliary stricture in 4 (15.3%) and bile leakage in 2 (7.6%). No vascular complications occurred. The RPSG volume was significantly smaller in recipients with BCs than in those without BCs (400.8±79.9 vs 504.1±96.5 mL, P = .015). The bile duct types were A, B, C1, C2, and D in 6 (18.8%), 5 (15.6%), 3 (9.4%), 13 (40.6%), and 5 (15.6%) patients, respectively. All the RPSGs had a single-orifice bile duct. The bile duct size of the RPSG was relatively smaller in recipients with BCs than in those without BCs (2.8±1.0 vs 3.6±1.4 mm, P = .237). CONCLUSIONS When the left liver volume is disproportionately small, selection of a donor with a type III PV variation can prevent BCs after SG and DG LDLTs using an RPSG.

Abstract
BACKGROUND Metabolic syndrome (MS) is the most common long-term complication after liver transplantation, and it has been increasing in incidence. The aim of this study was to clarify the risk factors for each MS component -hypertension, diabetes mellitus, and dyslipidemia-after living-donor liver transplantation (LDLT), including characteristics of living-donors. METHODS Data related to clinicopathological parameters including MS components in 461 consecutive patients who underwent LDLT were analyzed retrospectively. RESULTS Prevalence of all MS components (hypertension, diabetes mellitus, and dyslipidemia) increased from 9.3%, 16.5%, and 7.2% before LDLT to 44.9%, 45.3%, and 50.8% after LDLT, respectively. By multivariate logistic regression analysis, the three factors, cyclosporine use (OR 2.086, P = 0.001), recipient age (OR 1.036, P = 0.001), and BMI (OR 1.072, P = 0.026) were independent predictors for post-LDLT hypertension. Next, the three factors, male recipient (OR 2.471, P < 0.001), recipient age (OR 1.039, P = 0.002), and donor BMI (OR 1.124, P = 0.012) were independent for post-LDLT diabetes mellitus. The four factors, cyclosporine use (OR 2.015, P = 0.001), prolonged prednisolone use (OR 1.928, P = 0.002), recipient age (OR 1.019, P = 0.037), and GRWR (OR 0.316, P = 0.037) were independent for post-LDLT dyslipidemia as well. CONCLUSIONS Not only recipient-related factors but also donor-related factors were independently associated with each targeted post-LDLT MS component.

Abstract
Small-for-size graft (SFSG) syndrome after living donor liver transplantation (LDLT) is the dysfunction of a small graft, characterized by coagulopathy, cholestasis, ascites, and encephalopathy. It is a serious complication of LDLT and usually triggered by excessive portal flow transmitted to the allograft in the postperfusion setting, resulting in sinusoidal congestion and hemorrhage. Portal overflow injures the liver directly through nutrient excess, endothelial activation, and sinusoidal shear stress, and indirectly through arterial vasoconstriction. These conditions may be attenuated with portal flow modulation. Attempts have been made to control excessive portal flow to the SFSG, including simultaneous splenectomy, splenic artery ligation, hemi-portocaval shunt, and pharmacological manipulation, with positive outcomes. Currently, a donor liver is considered a SFSG when the graft-to-recipient weight ratio is less than 0.8 or the ratio of the graft volume to the standard liver volume is less than 40%. A strategy for transplanting SFSG safely into recipients and avoiding extensive surgery in the living donor could effectively address the donor shortage. We review the literature and assess our current knowledge of and strategies for portal flow modulation in LDLT.

Abstract
Background Hemophagocytic syndrome (HPS) is a rare and potentially fatal complication following liver transplantation. Case presentation A 63-year-old woman with decompensated liver cirrhosis secondary to hepatitis B virus infection underwent living donor liver transplantation using the right posterior section of her husband’s liver (graft volume, 581 g; 56.8% of the recipient’s standard liver volume). She developed small-for-size syndrome on postoperative day (POD) 7, and HPS was diagnosed on POD 12 by bone marrow aspiration (white blood cells, 300/μL; neutrophils, 30/μL). Given that she tested negative for viral (hepatitis B virus and cytomegalovirus) and bacterial infections, it was considered likely to be secondary HPS. Steroid pulse therapy was initiated, and her white blood cell count increased to 4290/μL on POD 15, indicating that her peripheral blood leukocytes had improved. There were no surgical complications, but the patient died of prolonged graft dysfunction with bacterial sepsis on POD 14. Conclusions We report a rare case of HPS occurring 2 weeks after living donor liver transplantation with a right posterior section graft, diagnosed early via bone marrow aspiration. This clinical course implies an association between HPS and graft dysfunction such as small-for-size syndrome. Further studies of the mechanism of hypercytokinemia-induced HPS are required to confirm the optimal treatment for HPS.

Use of a Right Lateral Sector Graft in Living Donor Liver Transplantation Is Feasible, but Special Caution Is Needed With Respect to Liver Anatomy. Am J Transplant 2016; 16:1258-65. [PMID: 26602536 DOI: 10.1111/ajt.13604] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2015] [Revised: 10/02/2015] [Accepted: 10/31/2015] [Indexed: 01/25/2023]
Abstract
Right lateral sector (RLS) grafting has been introduced to enlarge the potential donor pool for living donor liver transplantation (LDLT); however, evidence of its feasibility is limited. Data from 437 LDLTs carried out between 2000 and 2013 were analyzed retrospectively. LDLTs using a right liver graft (n = 251) were compared with those using a RLS graft (RLSG; n = 28). No donor mortality occurred, and the major complication rates were similar between the two groups. Postoperative liver function preservation was better in the RLSG donors. Concerning the recipients, the mortality and overall survival rates were similar between the two groups. The complication rate for the recipients was higher when more than two arterial or biliary anastomoses were necessary. A systematic literature search identified four reports on LDLT using RLSGs. Among 66 LDLTs, including the present series, there were no cases of donor death, and the rates of major and minor complications in the donors were 6% and 29%, respectively. The major complication and overall mortality rates in the recipients were 29% and 6%, respectively. LDLT using an RLSG is feasible, with an acceptable survival rate among the recipients.

Abstract
We conducted a retrospective investigation in order to clarify whether selecting the type of liver graft had an impact on outcomes of adult-to-adult living donor liver transplantation (AALDLT). Data from the medical records of the donors and the recipients of 321 consecutive cases of AALDLT performed between April 2004 and March 2014 were retrospectively analyzed. Our general criteria for selecting the type of liver graft was that a left graft was preferentially selected when the estimated volume of the left graft was ≥35% of the standard liver volume of the recipient, and that a right graft was selected only when the estimated remnant liver volume of the donor was ≥35% of the total liver volume. In this series, 177 left grafts, 136 right grafts, and 8 posterior grafts were used. The left grafts tended to have 2 or more arteries, whereas the right grafts tended to have 2 or more bile duct orifices. The graft survival curves and the incidences of severe complications were comparable between the AALDLT using right grafts and the AALDLT using left grafts. The preoperative estimation of graft size hardly enabled us to predict severe posttransplant complication. Moreover, small-for-size graft syndrome occurred regardless of the estimated graft volumes. Instead, donor age was a significant risk factor for small-for-size graft syndrome. In conclusion, left grafts should be more aggressively used for the sake of donors' safety. The use of hepatic grafts from older donors should be avoided if possible in order to circumvent troublesome posttransplant complications.

Correlation between portal vein anatomy and bile duct variation in 407 living liver donors. Am J Transplant 2015; 15:155-60.

Abstract
Our aim was to determine whether variant bile duct (BD) anatomy is associated with portal vein (PV) and/or hepatic artery (HA) anatomy. We examined the associations between BD anatomy and PV and/or HA anatomy in 407 living donor transplantation donors. We also examined whether the right posterior BD (RPBD) course was associated with the PV and/or HA anatomy. Variant PV, HA and BD anatomies were found in 11%, 25% and 25%, respectively, of 407 donors enrolled in this study. The presence of a variant BD was more frequently associated with a variant PV than with a normal PV (61% vs. 20%, p < 0.0001). By contrast, the presence of a variant HA was not associated with a variant BD. A supraportal RPBD was found in 357 donors (88%) and an infraportal RPBD was found in 50 donors (12%). An infraportal RPBD was significantly more common in donors with a variant PV than in donors with a normal PV (30% vs. 10%, p = 0.0004). Variant PV, but not variant HA, anatomies were frequently associated with variant BD anatomy. Additionally, an infraportal RPBD was more common in donors with a variant PV than in donors with a normal PV.
