Erythropoietic protoporphyria is a rare inherited metabolic disorder involving the heme biosynthesis pathway and leads to the accumulation of protopo-rphyrin in the erythrocytes or liver. Although peripheral neuropathy is known to develop occa-sionally in other types of porphyria, it rarely occurs in patients with erythropoietic protoporphyria. A 16-year-old boy was transferred to our hospital due to end-stage liver disease secondary to erythropoietic protoporphyria. Severe systemic peripheral neuropathy, similar to that presented in Guillain-Barré syndrome, developed; it was promptly managed with mechanical ventilation. Electrophysiological assessment of the presented neuropathy showed no responsiveness, indicating severe axonopathy. Six weeks after the transfer, liver transplant was performed. Postoperatively, hepatorenal syndromes improved immediately, and his erythrocyte protoporphyrin level decreased from 6291 to 174 μg/dL red blood cells. The patient started to move his limbs gradually and was weaned from mechanical ventilation 2 months after liver transplant. Eventually, he was discharged from hospital and was able to ambulate with assistance 10 months after liver transplant. To our knowledge, this is the first report detailing the clinical course in a patient with erythropoietic protoporphyria who recovered from severe systemic peripheral neuropathy after liver transplant.

Background: Immunosuppression during liver transplantation (LT) enables the prevention and treatment of organ rejection but poses a risk for severe infectious diseases. Immune modulation and antimicrobials affect the plasma microbiome. Thus, determining the impact of immunosuppression on the microbiome may be important to understand immunocompetence, elucidate the source of infection, and predict the risk of infection in LT recipients. We characterized the plasma microbiome of LT recipients at early post-LT and assessed the association between the microbiome and clinical events. Results: In this study, 51 patients who received LT at Nagoya University Hospital from 2016 to 2018 were enrolled. Plasma samples were retrospectively collected at the following time points: 1) within a week after LT; 2) 4 ± 1 weeks after LT; 3) 8 ± 1 weeks after LT; and 4) within 2 days after a positive blood culture. A total of 111 plasma samples were analyzed using shotgun next-generation sequencing (NGS) with the PATHDET pipeline. Relative abundance of Anelloviridae, Nocardiaceae, Microbacteriaceae, and Enterobacteriaceae significantly changed during the postoperative period. Microbiome diversity was higher within a week after LT than that at 8 weeks after LT. Antimicrobials were significantly associated with the microbiome of LT recipients. In addition, the proportion of Enterobacteriaceae was significantly increased and the plasma microbiome diversity was significantly lower in patients with acute cellular rejection (ACR) than non-ACR patients. Sequencing reads of bacteria isolated from blood cultures were predominantly identified by NGS in 8 of 16 samples, and human herpesvirus 6 was detected as a causative pathogen in one recipient with severe clinical condition. Conclusions: The metagenomic NGS technique has great potential in revealing the plasma microbiome and is useful as a comprehensive diagnostic procedure in clinical settings. Temporal dynamics of specific microorganisms may be used as indirect markers for the determination of immunocompetence and ACR in LT recipients.

Background: There are long-standing controversies about the transplant indications for alcoholic liver disease (ALD), because of the recognition that ALD is fundamentally self-inflicted. However, it is unclear whether psychosocial characteristics of ALD are different from that of non-alcoholic liver disease (NALD) in the selection of liver transplantation (LT) recipients. We aimed to clarify the psychosocial characteristics of ALD recipients (ALD-R)/ALD recipient candidates (ALD-RC) and NALD recipients (NALD-R)/ NALD recipient candidates (NALD-RC). Methods: From 2011 to 2019, 75 patients were enrolled in this prospective observational study (ALD-RC, n = 19; NALD-RC, n = 56), LT were carried out as follow; ALD-R, n = 6; NALD-R, n = 52. We evaluated psychosocial characteristics in the preoperative period and 3, 12 months after LT (ALD-R, n = 3/3; NALD-R, n = 28/25). The following scales were used to evaluate psychosocial characteristics: Visual Analogue Scale, Alcohol Use Disorders Identification Test, Hospital Anxiety and Depression Scale, Beck Depression Inventory, Brief Evaluation of Medication Influences and Beliefs, Social Support Questionnaire (SSQ), Temperament and Character Inventory, Parental Bonding Instrument (PBI), the Short Form Health Survey (SF-36). Results: When evaluating on the basis of abstinence rule, a comparison of ALD-RC and NALD-RC in the preoperative period identified similar patterns of psychosocial characteristics, except that the NALD-RC scored higher on the PBI item “overprotection from mother” (P < 0.05). The only significant difference between ALD-R and NALD-R after liver transplantation was in SSQ scores at 3 months. Conclusion: The psychosocial characteristics of ALD-RC and NALD-RC may be similar when evaluated on the basis of Japan’s abstinence rule. This result also imply that the psychosocial characteristics of ALD-RC may differ from the previously reported psychosocial characteristics of alcohol dependent patients. These findings have the potential to provide helpful information for the evaluation of ALD-RC.

Background: Chronic high Epstein–Barr virus loads (CHEBV) are commonly observed in pediatric liver transplant patients. However, it is unclear how CHEBV impacts the liver graft. The aim of this study was to clarify the clinical and pathological impacts of CHEBV on the liver graft. Methods: From 2012 to 2020, we retrospectively investigated 46 pediatric liver transplant patients (under 16 years) who survived ≥6 months. The patients were divided into two groups: CHEBV group (EBV DNA >10 000 IU/ml of whole blood for ≥6 months) and nonchronic high EBV (NCHEBV) group (patients who did not meet CHEBV criteria). Tacrolimus was reduced to <3.0 ng/ml in patients with EBV DNA >5000 IU/ml. Blood biochemistry data and pathological findings, obtained at the time of protocol and episodic biopsies, were compared between the two groups. Results: Out of 46 patients, 28 CHEBV and 18 NCHEBV patients were enrolled. The blood biochemical examination did not show a significant difference between the two groups. In addition, no significant differences between the two groups were found in the pathological findings, including frequency of late acute rejection and the progression of fibrosis at the time of both protocol and episodic biopsies. Appropriate adjustment of immunosuppression for CHEBV management may have contributed to the prevention of the progression of fibrosis. Conclusion: CHEBV had little adverse effect on the liver graft. Graft fibrosis might have been avoided through optimal dose modification of tacrolimus. Further long-term monitoring is necessary because CHEBV may affect the pediatric liver graft in the long term.

Objectives: In this study, we revisited the reasons for poorer prognosis after liver transplant in patients with hepatitis C virus, whose main causes of death were generally known to be recurrent disease. Materials and Methods: Between April 2003 and March 2017, among 132 patients who underwent liver transplant because of liver cirrhosis at our institution, 40 patients (30.3%) were positive for hepatis C virus. We retrospectively compared the overall survival after liver transplant in patients with and without hepatitis C virus infection. Furthermore, we investigated the causes of death in transplant recipients with hepatitis C virus infections. Results: In patients with hepatitis C virus infection, overall survival was 82.2%, 75.2%, and 50.8% at 1, 5, and 10 years, respectively, after liver transplant; these results were lower than those in patients without infection (94.5%, 87.0%, and 87.0% at 1, 5, and 10 years, respectively; P = .001). Among 40 patients with positive infection, 14 patients died after liver transplant. A main reason for death was hepatocellular carcinoma recurrence (3 patients). Surprisingly, only 1 patient died from hepatitis C virus-related complication (fibrosing cholestatic hepatitis); the remaining 10 patients died from reasons other than hepatitis C virus disease progression. Conclusions: Our results suggest that clinicians should not only be aware of hepatitis C virus recurrence but should also be aware of other unrelated complications in transplant recipients who are positive for this virus.

Acute liver failure (ALF) is a life-threatening illness that occurs in the absence of pre-existing liver disease. When symptoms seriously progress under continuous supportive medical care, liver transplantation becomes the only therapeutic strategy. However, the available sources of organs for liver transplantation differ worldwide. In regions in which organs from cadaveric donors are more common, deceased donor liver transplantation (DDLT) is performed in this urgent situation. Conversely, in countries where cadaveric donors are scarce, living donor liver transplantation (LDLT) is the only choice. Special considerations must be made for urgent LDLT for ALF, including the expedited evaluation of living donors, technical issues, and the limitations of ABO blood type combinations between recipients and donor candidates. In this review, we highlight the role of LDLT for ALF and the considerations that distinguish it from DDLT. LDLT is well-established as a life-saving procedure for ALF patients and there is often no alternative to LDLT, especially in countries where DDLT is not feasible. However, from a global perspective, an increase in the deceased donor pool might be an urgent and important necessity.

Background: In this study, we investigated long-term survival of cirrhotic patients without hepatocellular carcinoma (HCC) and the proper timing of liver transplantation in the era with recent progress of management. Methods: We first classified 217 non-transplant cirrhotic patients without HCC according to the long-term survival based on Child-Turcotte-Pugh (CTP) scores and the MELD scores. We then compared them with the survival after liver transplantation in 114 patients with liver cirrhosis. Results: We classified into four groups (class A as CTP score of 5,6, B as 7,8, C as 9-12, D as 13-15) according to the long-term survival of the patients, the survivals of patients with class C and D were significantly worse compared with transplant patients (P < 0.001 in each group). And we also classified into four groups based on the MELD scores (class A as MELD score of −8, B as 9-12, C as 13-19, D as 19-), the survivals of patients with class C and D were significantly worse compared with those of transplant patients (P < 0.001 in each group). Conclusions: Considering the long-term survival of patients with liver cirrhosis, CTP score of 9 and/or MELD score of 13 could be a proper timing for liver transplantation.

Background: Graft inflow modulation (GIM) during adult-to-adult living donor liver transplantation (LDLT) is a common strategy to avoid small-for-size syndrome, and some transplant surgeons attempt small size graft strategy with frequent GIM procedures, which are mostly performed by splenectomy, in LDLT. However, splenectomy can cause serious complications such as portal vein thrombosis and overwhelming postsplenectomy infection. Methods: Forty-eight adult-to-adult LDLT recipients were enrolled in this study and retrospectively reviewed. We applied the graft selection criteria, which routinely fulfill graft-to-recipient weight ratio ≥ 0.8%, and consider GIM as a backup strategy for high portal venous pressure (PVP). Results: In our current strategy of LDLT, splenectomy was performed mostly due to hepatitis C and splenic arterial aneurysms, but splenectomy for GIM was intended to only one patient (2.1%). The final PVP values ≤ 20 mmHg were achieved in all recipients, and no significant difference was observed in patient survival or postoperative clinical course based on whether splenectomy was performed or not. However, 6 of 18 patients with splenectomy (33.3%) developed postsplenectomy portal vein thrombosis (PVT), while none of the 30 patients without splenectomy developed PVT after LDLT. Splenectomy was identified as a risk factor of PVT in this study (P < 0.001). Our study revealed that a lower final PVP could be risk factor of postsplenectomy PVT. Conclusions: Using sufficient size grafts was one of the direct solutions to control PVP, and allowed GIM to be reserved as a backup procedure. Splenectomy should be avoided as much as possible during LDLT because splenectomy was found to be a definite risk factor of PVT. In splenectomy cases with a lower final PVP, a close follow-up is required for early detection and treatment of PVT.

Advanced liver cirrhosis is usually accompanied by portal hypertension. Long-term portal hypertension results in various vascular alterations. The systemic hemodynamic state in patients with cirrhosis is termed a hyperdynamic state. This peculiar hemodynamic state is characterized by an expanded blood volume, high cardiac output, and low total peripheral resistance. Vascular alterations do not disappear even long after liver transplantation (LT), and recipients with cirrhosis exhibit a persistent systemic hyperdynamic state even after LT. Stability of optimal systemic hemodynamics is indispensable for adequate portal venous flow (PVF) and successful LT, and reliable parameters for optimal systemic hemodynamics and adequate PVF are required. Even a subtle disorder in systemic hemodynamics is precisely indicated by the balance between cardiac output and blood volume. The indocyanine green (ICG) kinetics reflect the patient's functional hepatocytes and effective PVF, and PVF is a major determinant of the ICG elimination constant (k ICG) in the well-preserved allograft. The k ICG value is useful to set the optimal PVF during living-donor LT and to evaluate adequate PVF after LT. Perioperative management has a large influence on the postoperative course and outcome; therefore, key points and unexpected pitfalls for intensive management are herein summarized. Transplant physicians should fully understand the peculiar systemic hemodynamic behavior in LT recipients with cirrhosis and recognize the critical importance of PVF after LT.

A 39-year-old man was diagnosed with allopurinol-induced hepatic injury. He did not show any sign of hepatic encephalopathy, but his serum total bilirubin level was >40 mg/dL when he visited the local hospital. The therapeutic effects of initial medical treatments were transient, and both renal function and coagulation ability were gradually deteriorated. Four months after the onset of hepatic injury, he was referred to our hospital for the purpose of liver transplantation (LT). Although he was wasting and severely jaundiced, his consciousness level was not disturbed at all, with normal serum ammonia blood concentration before LT. Owing to allopurinol-induced severe cholestatic liver failure, living-donor LT (LDLT) was performed with the use of a right lobe graft from his younger brother. The explanted liver was extremely enlarged, with a weight of 2,480 g, and severely cholestatic. Microscopic findings were also compatible with drug-induced cholestatic liver injury. He was discharged from hospital 55 days after LDLT, whereas his renal dysfunction remained at 6 months after LT. There are 3 types of pathophysiology of drug-induced hepatotoxicity: hepatocellular, cholestatic, and mixed liver injury. Although allopurinol hepatotoxicity is rare, it can be severe and even fatal. This is the 1st case report of successful LDLT for a patient who had developed allopurinol-induced cholestatic liver failure.

Introduction Hepatic hemangioma is one of the most common benign liver tumors. There are few published reports regarding liver transplantation using liver allografts with hemangioma. Presentation of case A 45-year-old man was evaluated as a living donor for 19-year-old son with cirrhosis due to hepatic fibrosis. Preoperative investigations revealed 20 and 7 mm hemangiomas, at segment 2 (S2) and 4 (S4) respectively. Considering the anatomical relation of S2 hemangioma and Glisson 2, liver graft was designed as left lobe excluded S2 hemangioma by partial resection. Estimated graft recipient weight ratio (GRWR) even after partial resection of hemangioma was reasonable. During the donor operation, a partial hepatic resection of S2 hemangioma was performed. Intraoperative pathologic findings revealed a cavernous hemangioma, and then, the left hepatic graft with the caudate lobe was harvested. Actual GRWR was 0.90%. Donor's postoperative course was uneventful. Recipient's post-operative course was almost uneventful. Postoperative computed tomography of the recipient showed the graft regeneration without increase or recurrence of hemangioma. Discussion Organ shortage is a major concern in the field of liver transplantation. A novel donor source with a further option is extremely crucial for a guarantee of liver transplantation. We experienced the first case of adult-to-adult living donor liver transplantation using liver allograft after the resection of hemangioma. Conclusion We advocate that the use of liver allograft with hemangiomas in adult-to-adult LDLT settings can be remarkable strategy to reduce the problem of organ shortage without any unfavorable consequences in both living donor and recipient.

Tacrolimus is widely used as an immunosuppressant in liver transplantation, and tacrolimus-induced acute kidney injury (AKI) is a serious complication of liver transplantation. For early detection of AKI, various urinary biomarkers such as monocyte chemotactic protein-1, liver-type fatty acid-binding protein, interleukin-18, osteopontin, cystatin C, clusterin and neutrophil gelatinase-associated lipocalin (NGAL) have been identified. Here, we attempt to identify urinary biomarkers for the early detection of tacrolimus-induced AKI in liver transplant patients. Urine samples were collected from 31 patients after living-donor liver transplantation (LDLT). Twenty recipients developed tacrolimus-induced AKI. After the initiation of tacrolimus therapy, urine samples were collected on postoperative days 7, 14, and 21. In patients who experienced AKI during postoperative day 21, additional spot urine samples were collected on postoperative days 28, 35, 42, 49, and 58. The 8 healthy volunteers, whose renal and liver functions were normal, were asked to collect their blood and spot urine samples. The urinary levels of NGAL, monocyte chemotactic protein-1 and liver-type fatty acid-binding protein were significantly higher in patients with AKI than in those without, while those of interleukin-18, osteopontin, cystatin C and clusterin did not differ between the 2 groups. The area under the receiver operating characteristics curve of urinary NGAL was 0.876 (95% confidence interval, 0.800-0.951; P<0.0001), which was better than those of the other six urinary biomarkers. In addition, the urinary levels of NGAL at postoperative day 1 (p= 0.0446) and day 7 (p=0.0006) can be a good predictive marker for tacrolimus-induced AKI within next 6 days, respectively. In conclusion, urinary NGAL is a sensitive biomarker for tacrolimus-induced AKI, and may help predict renal event caused by tacrolimus therapy in liver transplant patients.

The goal of this study was to examine whether the lower limit of the graft-to-recipient weight ratio (GRWR) can be safely reduced to make better use of the left lobe graft in adult-to-adult living donor liver transplantation in combination with portal pressure control. Beginning December 2007, the acceptable limit for GRWR was lowered to ≥0.7% and by April 2009, it was further lowered to ≥0.6%. A portal pressure control program targeting a final portal pressure <15 mm Hg was also introduced. The donor complication rate decreased from 13.8% to 9.3%. The overall survival of recipients with GRWR <0.8% did not differ from recipients with a GRWR ≥0.8%. In conclusion, the lower limit of the GRWR can be safely reduced to 0.6% using a left lobe graft in adult-toadult living donor liver transplantation in combination with portal pressure control.

切除不能な肝門部領域胆管癌に対する生体肝移植（先進医療として2022年9月1日に告示）の付随研究として肝移植レシピエント中の摘出肝の臨床病理学的検討、循環腫瘍細胞の解析、摘出肝の腫瘍部および非腫瘍部のmRNA発現の網羅的解析、免疫抑制剤存在下における腫瘍増殖解析およびレシピエント・ドナーの腫瘍免疫に関わる一塩基多型解析を行い、治癒に至る分子生物学的な特性を解明する。本研究は肝門部領域胆管癌のみならず難治がんの多い肝・胆道がんの治療体系を大きく変革し、予後の飛躍的な向上に寄与することが高く期待される。
切除不能な肝門部領域胆管癌（1. 肝機能が不良、もしくは残肝容積が小さい症例、2. 予定残肝の流入・流出血管へのがん浸潤で血行再建が困難・不能な症例、3. 胆管分離限界点の近傍への腫瘍浸潤症例、4. 原発性硬化性胆管炎に合併した局在不明の胆管癌）に対する肝移植手術について、欧米ではすでに長期予後の改善が報告されガイドライン上で推奨されている。肝移植手術の本邦における安全性・有効性を検証するべく、2022年9月1日に厚生労働省告示第265号「生体肝移植：切除が不能な肝門部胆管がん」として先進医療Bの枠組みで第I/II相多施設共同前向き単群介入研究が告示された。切除不能な肝門部領域胆管癌に対する生体肝移植を施行した患者を移植後3年間前向きに追跡し、術後３年全生存率が主要評価項目となる（jRCT1070220052）。
本研究では、レシピエントの治癒を達成するための分子生物学的な特性を明らかにする。具体的には、1)摘出肝の臨床病理学的検討、2)循環腫瘍細胞（circulating tumor cells: CTCs）の解析、3)摘出肝の腫瘍部および非腫瘍部のmRNA発現の網羅的解析、4)免疫抑制剤存在下における腫瘍増殖解析、5)レシピエント・ドナーの腫瘍免疫に関わる一塩基多型（single nucleotide polymorphism: SNP）解析を行い、治癒に関与する因子を特定する。
令和6年度に6症例（令和5年度に同意取得の1例を含む）に対して、適応中央判定委員会を開催し、全6例が本試験に登録された。2例は登録後の癌の進行により非切除因子が判明し移植を実施せず、非移植群となったものの、残り4例に対して生体肝移植術が実施され、本研究用のサンプルが採取された。いずれの症例も手術後退院され、経過観察中である。
初年度の患者登録は1件に留まったが、令和6年度は5件の登録に至った。本研究の周知が少しずつ進んだためと考えている。現時点で研究全体での登録症例数は6例（目標症例数20例、移植群4例、非移植群2例）となり、概ね当初の計画通りの進捗である。
肝門部領域胆管癌診療の拠点病院である全国8施設で登録候補となる症例のリクルートメントを進めると共に、元々登録候補となる症例数が極めて少数であることをふまえ、関連学会（日本移植学会、日本肝移植学会、日本肝胆膵外科学会、日本消化器外科学会、日本消化器病学会、日本肝臓学会、日本胆道学会）のホームページにおける周知および国内外の学術集会における講演、さらに患者会（デイジーの会）を通じた研究概要の周知および患者紹介依頼を行う。また、移植実施施設だけでなく、紹介機関となる研究協力機関を含めて班会議を2回開催し、症例のリクルート、移植実施症例の共有を図る。

小児肝移植症例では移植後免疫抑制療法下にEstein-Barr (EB) ウイルスの初感染となることが稀でなく、そのためその後高EBウイルス血症が長期にわたり持続する症例も多い。しかしその病態や臨床的意義、長期予後への影響は不明である。一方、小児肝移植領域では長期生存が重要とされるが、近年血液検査上肝機能に異常がなくてもグラフト肝の線維下が進行していることが問題視されているがその原因は未だ解明されていない。持続性高EBウイルス血症を認める小児生体肝移植症例についてウイルス学的・免疫学的な解析を行いその病態を解明するとともに、肝炎を引き起こすことでも知られるEBウイルスがグラフト肝に与える影響を病理組織学的にも検討し解明することを目的としている。肝移植後高EBウイルス血症を引き起こす病態が解明され、その特徴や特異性が解明されればその治療法や予防法も確立することが可能であると予想され、小児肝移植長期予後の向上に大きく貢献するものと考えられる。グラフト肝の評価としては肝線維化マーカーの測定に加えプロコトール肝生検により病理組織学的にも評価し２群間で比較検討する。特にEBウイルス高値群ではEBERsによる染色も行い評価する。当院にて生体肝移植を施行した小児症例に対して、入院中は週一度、外来通院加療中は４－６週間ごとにリアルタイムPCR法を用いた定量法でEBウイルス量を測定している。全血EBV-DNA量が10000IU/ml以上の状態が６ヶ月以上持続した症例をEBV持続高値群とした場合、約４割が持続高値群となっている。

According to the analysis of deceased donor split liver transplantation (SLT),including 36 cases undergoing the operation by the end of 2014, the outcome was satisfactory and compatible with the previously published data. However, the incidence of surgical complications was relatively high, and those complications tended to occur in the patients receiving right-sided split grafts. In terms of the donor criteria for SLT, it would be suitable to use the Western countries' criteria, including donor age (younger than 50 years), liver function tests (within 3 times of the upper normal limits), and less than mild steatosis. Critically-ill patients and retransplant patients have to be avoided as SLT recipient candidates, although it would not be possible to be applied at present owing to the shortage of deceased donor organs. The splitting procedure may be reconsidered to prevent surgical complications and in-situ splitting procedure may be favorable instead of ex-vivo splitting procedure.

Recipients' re-drinking in 20-50% after liver transplantation for alcoholic liver failure is a social problem that could negate transplanted organs provided free of donor. Psychosocial evaluation and long-term follow-up from the preoperative point of view are also important worldwide.
We created psychosocial criteria and compared retrospectively with "candidate for transplant recipients for alcoholic liver failure" and "candidate for other liver transplant recipients" to investigate the comprehensive factors. We have been conducting retrospective examination using psychosocial evaluation criteria established at our hospital, and we have clarified the effectiveness of this evaluation method so far at the conference.

We established small-for-size graft liver transplantation model in pig, which is 30% partial liver graft volume using right-lateral lobe. We investigated the effect of nitric oxide (NO) gas during liver preservation on small-for-size livers after transplantation. Gaseous oxygen with NO (40 ppm) was insufflated into the livers through the suprahepatic vena cava during cold storage (VSNOP group). Livers in Control group was preserved by simple cold storage.
One recipients in VSNOP group survived for 7 days, and the survival rates in VSNOP group tended to be better compared with control group. Pressure gradient between portal vein and inferior vena cava of livers preserved by VSNOP tended to be lower compared with the control livers just behind portal reperfusion.

Thrombotic microangiopathy (TMA) is one of the life threatening diseases, which characterized by aggregation of platelets in systemic circulation, and therefore multiple organ dysfunction. The purpose of this study is to clarify the clinical characteristics and prognostic factors of TMA after liver transplantation (LTx). A total of 290 LTx patients from April 2006 to March 2013 were evaluated. We elucidated that the ADAMTS13 activity decreased by more than half in all patients and that TMA is an inevitable process after LTx because of cold-ischemia/warm-reperfusion (CI/WR) during graft preservation. Pathological Confirmation revealed that sinusoidal injury after CI/WR activated complement system, thus regulation of complement activation could be the target to improve the early outcome after LTx.

Liver transplant outcomes using grafts donated after cardiac death (DCD) remain poor. Our goal of this study was to extend the warm ischemic time in rat liver transplantation from DCD donors. For this purpose, it is important to control the ischemic/reperfusion (I/R) injury after transplantation. There are a couple of reports to prevent I/R injury, and we applied venous systemic oxygen persufflation (VSOP) and nitric oxide (NO) gas administration.
Using rat liver transplantation models from 60 minutes DCD donors, VSOP-NO treatment could effectively decreasing the damage of I/R injury, leading to the better survival. However, we failed to extend the warm ischemic time by this methods. There may be a limitation in these graft reconditioning procedures, further investigation to understand this phenomena is required.
