Abstract
Early allograft dysfunction (EAD) after liver transplantation is a significant clinical problem that negatively impacts graft and patient outcomes. The rising incidence of EAD and what it means concerning living donor liver transplantation (LDLT) is an area of great interest. However, EAD after LDLT is a complex research topic yet to be reviewed comprehensively. Most of the literature on EAD is based on experience in deceased donor liver transplantation, and limited information is available in the context of LDLT. Thus, in this review, we present an overview of EAD after LDLT and have attempted to present balanced points of view on all its aspects, such as definitions, pathogenesis, risk factors, predictive markers, and management. The review aims to broadly overview the nature and extent of ongoing research evidence on this complex topic and inform practice in the field by identifying key concepts and knowledge gaps and highlighting areas that require further inquiry.

Intraoperative High Fraction of Inspiratory Oxygen is Independently Associated with Worse Outcome After Living-Donor Liver Transplantation: A Retrospective Study. World J Surg 2022; 46:1776-1787. [PMID: 35419624 PMCID: PMC9007621 DOI: 10.1007/s00268-022-06544-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 03/19/2022] [Indexed: 11/26/2022]
Abstract
Background Ischemia and reperfusion injury is an important factor that determines graft function after liver transplantation, and oxygen plays a crucial role in this process. However, the relationship between the intraoperative high fraction of inspiratory oxygen (FiO2) and living-donor-liver-transplantation (LDLT) outcome remains unclear. Patients and Methods A total of 199 primary adult-to-adult LDLT cases in Kyoto University Hospital between January 2010 and December 2017 were enrolled in this study. The intraoperative FiO2 was averaged using the total amount of intraoperative oxygen and air and defined as the calculated FiO2 (cFiO2). The cutoff value of cFiO2 was set at 0.5. Results Between the cFiO2 <0.5 (n = 156) and ≥0.5 group (n = 43), preoperative recipients’ background, donor factors, and intraoperative parameters were almost comparable. Postoperatively, the cFiO2 ≥0.5 group showed a higher early allograft dysfunction (EAD) rate (P = 0.049) and worse overall graft survival (P = 0.036) than the cFiO2 <0.5 group. Although the cFiO2 ≥0.5 was not an independent risk factor for EAD in multivariable analysis (OR 2.038, 95%CI 0.992–4.186, P = 0.053), it was an independent risk factor for overall graft survival after LDLT (HR 1.897, 95%CI 1.007–3.432, P = 0.048). Conclusion The results of this study suggest that intraoperative high FiO2 may be associated with worse graft survival after LDLT. Avoiding higher intraoperative FiO2 may be beneficial for LDLT recipients. Supplementary Information The online version contains supplementary material available at 10.1007/s00268-022-06544-7.

Elevated levels of circulating mitochondrial DNA predict early allograft dysfunction in patients following liver transplantation. J Gastroenterol Hepatol 2021; 36:3500-3507. [PMID: 34425021 DOI: 10.1111/jgh.15670] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/03/2021] [Revised: 08/02/2021] [Accepted: 08/10/2021] [Indexed: 01/08/2023]
Abstract
BACKGROUND AND AIM The role of circulating mitochondrial DNA (cmtDNA) in transplantation remains to be elucidated. cmtDNA may be released into the circulation as a consequence of liver injury; yet recent work also suggests a causative role for cmtDNA leading to hepatocellular injury. We hypothesized that elevated cmtDNA would be associated with adverse events after liver transplantation (LT) and conducted an observational cohort study. METHODS Twenty-one patients were enrolled prospectively prior to LT. RESULTS Postoperative complications were observed in 47.6% (n = 10). Seven patients (33.3%) had early allograft dysfunction (EAD), and six patients (28.5%) experienced acute cellular rejection within 6 months of LT. cmtDNA levels were significantly elevated in all recipients after LT compared with healthy controls and preoperative samples (1 361 937 copies/mL [IQR 586 781-3 399 687] after LT; 545 531 copies/mL [IQR 238 562-1 381 015] before LT; and 194 562 copies/mL [IQR 182 359-231 515] in healthy controls) and returned to normal levels by 5 days after transplantation. cmtDNA levels were particularly elevated in those who developed EAD in the early postoperative period (P < 0.001). In all patients, there was initially a strong overall positive correlation between cmtDNA and plasma hepatocellular enzyme levels (P < 0.05). However, the patients with EAD demonstrated a second peak in cmtDNA at postoperative day 7, which did not correlate with liver function tests. CONCLUSIONS The early release of plasma cmtDNA is strongly associated with hepatocellular damage; however, the late surge in cmtDNA in patients with EAD appeared to be independent of hepatocellular injury as measured by conventional tests.

Medicine (Baltimore) 2021; 100:e27075. [PMID: 34449508 PMCID: PMC8389916 DOI: 10.1097/md.0000000000027075] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/23/2021] [Accepted: 08/12/2021] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Secondary Budd-Chiari syndrome (BCS) occurs due to a blockage in the liver caused by invasion or compression by a large lesion. Conventional treatments for BCS do not solve practical problems, wherease liver transplantation has been only applied as a last-resort therapy and as the only opportunity for a radical cure. We explored the feasibility of applying ex vivo liver resection and autotransplantation (ELRA) for the new indications of treating patients with end-stage hepatic alveolar echinococcosis (HAE). Our center has firstly proposed the idea and successfully treated the 49 patients with HAE. This article for the first time reports the application of ELRA in treating patients with BCS secondary to HAE. METHODS According to the degree of lesion invasion and surgical options, 11 patients were divided into 4 types. These 11 patients had large lesions that invaded the second and third hilum of the caudate lobe and involved the confluence of the hepatic vein and the inferior vena cava, suprahepatic vena cava, or at least 2 hepatic veins and led to secondary BCS. The aim of the present work was to report 11 patients with life-threatening diseases who underwent ELRA (ex vivo liver resection and autotransplantation) for secondary BCS, to propose a classification system for secondary BCS, and to suggest that secondary BCS is an indication for ELRA. RESULTS Eleven patients successfully underwent ELRA without intraoperative mortality. The median autograft weight was 690 g (440-950 g); operative time was 12.5 hours (9.4-16.5 hours); Postoperative hospital stay was 15 days (7-21 days). Clavien-Dindo grade IIIa or higher postoperative complications occurred in only 5 patients. CONCLUSIONS This article for the first time reports the application of ELRA in treating patients with BCS secondary to HAE, not only provides new ideas for alternative treatments of secondary BCS, but also provides a classification system for secondary BCS. This article describes the technical process of outflow tract reconstruction and the experience for expanding the indications for ELRA. Our study demonstrated that ELRA is well feasible for treatment of BCS secondary to advanced HAE.

Abstract
Liver transplantation is the treatment of choice for end-stage liver diseases. However, early allograft dysfunction (EAD) is frequently encountered and associated with graft loss or mortality after transplantation. This study aimed to establish a predictive model of EAD after living donor liver transplantation. A total of 77 liver transplants were recruited to the study. Multivariate analysis was utilized to identify significant risk factors for EAD. A nomogram was constructed according to the contributions of the risk factors. The predictive values were determined by discrimination and calibration methods. A cohort of 30 patients was recruited to validate this predictive model. Four independent risk factors, including donor age, intraoperative blood loss, preoperative alanine aminotransferase (ALT), and reperfusion total bilirubin, were identified and used to build the nomogram. The c-statistics of the primary cohort and the validation group were 0.846 and 0.767, respectively. The calibration curves for the probability of EAD presented an acceptable agreement between the prediction by the nomogram and the actual incidence. In conclusion, the study developed a new nomogram for predicting the risk of EAD following living donor liver transplantation. This model may help clinicians to determine individual risk of EAD following living donor liver transplantation.

Vascular infiltration-based surgical planning in treating end-stage hepatic alveolar echinococcosis with ex vivo liver resection and autotransplantation. Surgery 2018; 165:889-896. [PMID: 30591376 DOI: 10.1016/j.surg.2018.11.007] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2018] [Revised: 10/30/2018] [Accepted: 11/16/2018] [Indexed: 02/08/2023]
Abstract
BACKGROUND For end-stage hepatic alveolar echinococcosis, insufficient guidance is available regarding surgical treatment, especially for ex vivo liver resection combined with autotransplantation. The indications for this complex surgery require further discussion. METHOD We reviewed 50 cases of patients who underwent ex vivo liver resection combined with autotransplantation from January 2014 to February 2018. A newly developed classification was used to describe vascular infiltration in all patients, who were divided into four groups based on anatomic lesion features and surgical patterns. The surgical planning for ex vivo liver resection combined with autotransplantation is then thoroughly discussed according to the gathered information. RESULTS In all patients, the length of the operation and the anhepatic phase were 735 minutes (range, 540-1,170 minutes) and 309 minutes (range, 122-480 minutes), respectively. The median remnant liver volume-to-standard liver volume ratio was 0.58 (range, 0.32-1.11). The rate of complications classified as Clavien-Dindo grade III or higher was 22% (11/50). A total of 3 postoperative deaths occurred. We identified 4 types with distinguished lesion anatomic features. Type I patients required more frequent unconventional reconstruction of the portal vein and bile duct than the other patients. Of the 6 type IV patients, 4 required modification of the surgical protocol according to intraoperative findings. CONCLUSION Vascular infiltration-based classification could improve the anatomic comprehension and, thus, facilitate surgical planning for ex vivo liver resection combined with autotransplantation. Through cautious evaluation of operability, liver function, and residual liver volume, together with delicate operative techniques and careful postoperative management, ex vivo liver resection combined with autotransplantation can achieve good results in the treatment of end-stage hepatic alveolar echinococcosis.

Abstract
Ex vivo liver resection combined with autotransplantation is a recently introduced approach to cure end-stage hepatic alveolar echinococcosis (HAE), which is considered unresectable by conventional radical resection due to echinococcal dissemination into the crucial intrahepatic conduits and adjacent structures. This article aims discuss the manipulation details and propose reasonable indications for this promising technique. All patients successfully underwent liver autotransplantation with no intraoperative mortality. The median weight of the autografts was 636 g (360-1300 g), the median operation time was 12.5 hours (9.4-19.5 hours), and the median anhepatic phase was 309 minutes (180- 460 minutes). Intraoperative blood loss averaged 1800 mL (1200-6000 mL). Postoperative complications occurred in 13 patients during hospitalization; 5 patients experienced postoperative complications classified as Clavien-Dindo grade III or higher, and 2 patients died of intraabdominal bleeding and acute cerebral hemorrhage, respectively. Twenty-nine patients were followed for a median of 14.0 months (3-42 months), and no HAE recurrence was detected. The technique requires neither an organ donor nor any postoperative immunosuppressant, and the success of the treatment relies on meticulous preoperative assessments and precise surgical manipulation.
