ELS could be summarized into three major categories, namely, ex-situ liver resection and autotransplantation(ELRA), ante-situm liver resection and autotransplantation(ALRA) and auxiliary partial liver autotransplantation(APLA). The successful development of ELS during the past 37 years is definitely inseparable from continuous effort s done by Chinese surgeons and researchers. Especially, the precision liver surgery paradigm has allowed to transform ELS into a modularized, more simplified, and standardized surgery, to upgrade surgical skills, to improve peri-operative outcome and long-term survival, to increase the capability of surgeons to select more complex diseases and to expand the level of medical service to the population. This review highlights the Chinese contributions to the field of ELS, focusing thereby on features of different surgical types, technical innovations, disease selection and surgical indication, patient prognosis and future perspectives.展开更多

There have been many publications on NCNNLM; however, its background heterogeneity makes it difficult to reach a specific conclusion. This heterogeneous disease group should be discussed in the order from its general to specific aspect. The present review paper describes the general prognosis and risk factors associated with NCNNLM while specifically focusing on the liver metastases of each primary disease. A multidisciplinary approach that takes into consideration appropriate timing for hepatectomy combined with chemotherapy may prolong survival and/or contribute to the improvement of the quality of life while giving respite from systemic chemotherapy.展开更多

A significant gap still exists between the number of available donor organs and potential recipients. The use of an otherwise-wasted resected liver lobe from patients with benign liver tumors is a new, albeit small, option to alleviate the allograft shortage.

文摘Acute liver failure(ALF)is a rare but life-threatening condition marked by rapid hepatic dysfunction,coagulopathy and encephalopathy in patients without prior liver disease.Common causes include drug-induced liver injury,viral hepatitis,and metabolic or autoimmune disorders.This review provides an updated overview of ALF’s etiology,diagnosis,and management.Timely diagnosis and risk stratification using tools like the King’s College Criteria and Model for End-Stage Liver Disease score are critical for guiding care.Early identification of etiology allows targeted treatments,such as N-acetylcysteine for acetaminophen toxicity or antivirals for hepatitis.Supportive care in specialized intensive care units,focused on hemodynamics,cerebral edema prevention,and metabolic stabilization,remains the cornerstone of management.Advances in extracorporeal liver support systems,such as molecular adsorbent recirculating systems and plasma exchange,offer promising bridges to recovery or liver transplantation-the definitive treatment for irreversible liver injury.Expanded donor criteria and improved allocation policies have enhanced transplantation access.Despite progress,ALF carries significant morbidity and mortality.Emerging therapies,including stem cell treatments and immunomodulatory agents,show potential to revolutionize care.This review emphasizes the need for a multidisciplinary approach and continued research to improve outcomes and refine therapeutic strategies.

文摘Liver transplantation represents a complex surgical procedure and serves as a curative treatment for patients presenting an acute or chronic end-stage liver disease, or carefully selected liver malignancy. A significant gap still exists between the number of available donor organs and potential recipients. The use of an otherwise-wasted resected liver lobe from patients with benign liver tumors is a new, albeit small, option to alleviate the allograft shortage. This review provides evidence that resected liver lobes may be used successfully in liver transplantation.

文摘The prognosis of drug-induced acute liver failure(ALF)is poor,with a survival rate of 27.1%without liver transplantation.Liver transplantation significantly improved survival rates to 66.2%.[1]The shortage of available grafts can be addressed by living donor liver transplantation(LDLT),an effective and safe method that expands the donor pool,enhances timely transplantation,and improves patient survival.
文摘Liver diseases are among the most insidious and life-threatening conditions due to their progressive nature and late symptom onset.Cirrhosis and hepatocellular carcinoma account for most liver-related deaths,often following the progression from fibrosis.Fibrosis creates a hostile microenvironment,characterized by portal hypertension,vascular capillarization,intrahepatic vasoconstriction,and extracellular matrix deposition,which severely limits drug efficacy.Advances in pharmaceutical science have prompted efforts to develop liver-targeted drug delivery systems to prevent or reduce the progression of fibrosis,a central feature of many liver diseases.Fibrosis often reduces the in vivo efficacy of both approved and experimental drugs,underscoring the need for improved delivery strategies focused on stability,controlled release,and precise targeting.Nanoparticle(NP)-based systems show promise,either by delivering therapeutic agents,or in some cases,by contributing directly to the therapeutic effects.This review summarizes the main types of NPs explored for liver disease treatment,especially those aiming to reverse fibrosis or prevent its progression,a critical therapeutic target in chronic liver diseases.Additionally,it examines gene delivery and ultrasoundguided microbubble strategies,which can be combined with NPs to improve cellspecific targeting and boost therapeutic effects.Together,these approaches have the potential to address current therapeutic challenges and accelerate the development of liver-targeted treatments for clinical application.
文摘Over the past six decades,liver transplantation(LT)has evolved from an experimental procedure into a standardized and life-saving intervention,reshaping the landscape of organ transplantation.Driven by pioneering breakthroughs,technological advancements,and a deepened understanding of immunology,LT has seen remarkable progress.Some of the most notable breakthroughs in the field include advances in immunosuppression,a revised model for end-stage liver disease,and artificial intelligence(AI)-integrated imaging modalities serving diagnostic and therapeutic roles in LT,paired with ever-evolving technological advances.Additionally,the refinement of transplantation procedures,resulting in the introduction of alternative transplantation methods,such as living donor LT,split LT,and the use of marginal grafts,has addressed the challenge of organ shortage.Moreover,precision medicine,guiding personalized immunosuppressive strategies,has significantly improved patient and graft survival rates while addressing emergent issues,such as short-term complications and early allograft dysfunction,leading to a more refined strategy and enhanced postoperative recovery.Looking ahead,ongoing research explores regenerative medicine,diagnostic tools,and AI to optimize organ allocation and posttransplantation car.In summary,the past six decades have marked a transformative journey in LT with a commitment to advancing science,medicine,and patient-centered care,offering hope and extending life to individuals worldwide.
文摘Liver transplantation(LT)has made significant progress in the treatment of end stage liver disease(ESLD).However,many patients still die from disease progression while awaiting transplantation.As the number of patients on LT waiting lists is increasing,and the organ shortage crisis is obvious,various efforts have been made to increase the pool of available liver grafts[1].In addition to living donor liver transplantation(LDLT),improving the utilization rate of extended criteria donor(ECD)livers is an important way.However,under traditional cold storage,ECD livers are usually associated with a higher risk of ischemic biliary disease,early allograft dysfunction(EAD)or even primary nonfunction(PNF).The frequently described definition in the literature for ECD grafts generally includes elderly,steatotic,long cold ischemia time(CIT),grafts obtained from donation after circulatory death(DCD),split liver grafts,donors with increased risk of infectious disease transmission and prolonged donor intensive care unit stay[2].
文摘Liver transplantation is a life-saving procedure for patients with end-stage liver diseases and acute liver failure.With advances in surgical techniques and immunosuppressive regimens,patient survival rates have significantly improved.While the systemic complications of post-transplantation are well recognized,ophthalmic manifestations remain underreported.Ophthalmic complications can significantly impair visual function and increase morbidity in these patients.Prolonged immunosuppression makes the patients susceptible to the opportunistic pathogens such as Cytomegalovirus,Candida,Aspergillus,etc.Other common findings include dry eye disease,cataracts and retinal vascular complications which further contribute to the long-term morbidity in these patients.Early ophthalmic evaluation and prompt management are essential to prevent irreversible vision loss and improve post-transplant outcomes.High index of suspicion and multidisciplinary approach is essential to facilitate early diagnosis and treatment.This review highlights the range of ophthalmic complications observed in liver transplant recipients and underscores the need for future research focused on understanding the underlying pathophysiological mechanisms and refining the prophylactic protocols to improve outcomes in this unique patient population.
文摘Liver transplantation(LT)remains the optimal life-saving intervention for patients with end-stage liver disease.Despite the recent advances in LT several barriers,including organ allocation,donor-recipient matching,and patient education,persist.With the growing progress of artificial intelligence,particularly large language models(LLMs)like ChatGPT,new applications have emerged in the field of LT.Current studies demonstrating usage of ChatGPT in LT include various areas of application,from clinical settings to research and education.ChatGPT usage can benefit both healthcare professionals,by decreasing the time spent on non-clinical work,but also LT recipients by providing accurate information.Future potential applications include the expanding usage of ChatGPT and other LLMs in the field of LT pathology and radiology as well as the automated creation of discharge summaries or other related paperwork.Additionally,the next models of ChatGPT might have the potential to provide more accurate patient education material with increased readability.Although ChatGPT usage presents promising applications,there are certain ethical and practical limitations.Key concerns include patient data privacy,information accuracy,misinformation possibility and lack of legal framework.Healthcare providers and policymakers should collaborate for the establishment of a controlled framework for the safe use of ChatGPT.The aim of this minireview is to summarize current literature on ChatGPT in LT,highlighting both opportunities and limitations,while also providing future possible applications.
文摘Artificial intelligence(AI)is revolutionizing medical imaging,particularly in chronic liver diseases assessment.AI technologies,including machine learning and deep learning,are increasingly integrated with multiparametric ultrasound(US)techniques to provide more accurate,objective,and non-invasive evaluations of liver fibrosis and steatosis.Analyzing large datasets from US images,AI enhances diagnostic precision,enabling better quantification of liver stiffness and fat content,which are essential for diagnosing and staging liver fibrosis and steatosis.Combining advanced US modalities,such as elastography and doppler imaging with AI,has demonstrated improved sensitivity in identifying different stages of liver disease and distinguishing various degrees of steatotic liver.These advancements also contribute to greater reproducibility and reduced operator dependency,addressing some of the limitations of traditional methods.The clinical implications of AI in liver disease are vast,ranging from early detection to predicting disease progression and evaluating treatment response.Despite these promising developments,challenges such as the need for large-scale datasets,algorithm transparency,and clinical validation remain.The aim of this review is to explore the current applications and future potential of AI in liver fibrosis and steatosis assessment using multiparametric US,highlighting the technological advances and clinical relevance of this emerging field.
文摘BACKGROUND Robotic assistance is increasingly used for donor and recipient hepatectomy in liver transplantation,yet existing evidence is fragmented and variably indirect.AIM To evaluate clinical outcomes,surgical performance,and economic effects of robotic-assisted donor and recipient hepatectomy in the transplant pathway.METHODS Following Preferred Reporting Items for Systematic reviews and Meta-Analyses 2020 and a priori registration,systematic reviews were included with or without meta-analysis.Four databases were searched through July 2025.Methodological quality was appraised with a measurement tool to assess systematic reviews(AMSTAR 2),and certainty was graded with grading of recommendations assessment,development and evaluation(GRADE).Evidence overlap was calculated via a citation-matrix-based corrected covered area(CCA).Effect sizes were prespecified as risk ratios(RR)for dichotomous outcomes and mean differences for continuous outcomes.RESULTS Five reviews met the inclusion criteria,four with meta-analyses and one consensus review used only for context.Donor(direct)findings were more favorable for robotics in terms of estimated blood loss(≈-117 mL)and length of stay(≈-0.6 days),although with longer operative time(≈+105 minutes).Absolute risks for donor complications were not estimable from ratio-only data.Recipient(indirect)meta-analysis indicated robotics to be favorable in terms of conversion(RR≈0.41)and severe morbidity(RR≈0.81),with a trend toward lower overall morbidity(RR≈0.92)and no difference in 30-day mortality.Differences in length of stay and operative time were small and heterogeneous.Economic evidence(indirect,network meta-analysis)suggested higher procedural costs for robotic vs laparoscopic intervention,but lower hospitalization costs vs open intervention,with laparoscopy the least expensive overall.AMSTAR 2 ratings were moderate-to-high across the reviews,GRADE certainty was low for key donor continuous outcomes,and low-to-moderate for recipient and economic outcomes.Overlap was slight(graded-corpus CCA=0.0%;including a contextual non-transplant review increased CCA to≈1.25%).CONCLUSION Robotic donor hepatectomy confers perioperative advantages at the cost of longer operative time.Recipient and economic findings are indirect and considered hypothesis-generating.Transplant-specific,prospective comparisons using a minimum standardized dataset and uniform outcome definitions are needed to resolve remaining uncertainties and to clarify the cost-utility correlation.
文摘BACKGROUND Perimenopausal women are prone to anxiety and depression due to fluctuating hormone levels,which significantly impair their quality of life.The current treatments have certain limitations.In traditional Chinese medicine,liver-soothing formulas are commonly prescribed for mood-related disorders,but their overall efficacy in perimenopausal anxiety and depression remains uncertain and requires verification through meta-analysis.AIM To provide evidence-based support for clinical decision-making and research,a meta-analysis was conducted to evaluate the effectiveness of liver-soothing formulas in treating perimenopausal anxiety and depression.METHODS Relevant studies published up to April 2025 were retrieved from ClinicalTrials.gov,PubMed,Web of Science,EMBASE,and the Cochrane Library.Eligible studies were screened according to predefined inclusion and exclusion criteria.Data were extracted and analyzed using the Stata 12.0 software.RESULTS After searching and screening,12 articles involving 1798 patients(922 in the treatment group and 876 in the control group)were included in the analysis.Meta-analysis showed that the standardized scores for anxiety[standardized mean difference(SMD)=-0.71,95%confidence interval(95%CI):-1.06 to-0.36]and depression(SMD=-0.67,95%CI:-1.06 to-0.27)of the treatment group were lower than those of the control group.Subgroup analysis results revealed that for anxiety,liver-soothing formulas used alone(SMD=-0.34,95%CI:-0.50 to-0.18)or in combination(SMD=-0.88,95%CI:-1.43 to-0.34)both significantly reduced scores compared with the control group.For depression,monotherapy of liversoothing formulas showed no significant statistical difference between the treatment and control groups(SMD=-0.47,95%CI:-1.11 to 0.17),whereas combination therapy produced significantly lower standardized scale scores in the treatment group than in the control group,with a statistically significant difference(SMD=-0.83,95%CI:-1.39 to-0.28).Regarding Greene scores,no statistically significant difference was observed with monotherapy(SMD=0.87,95%CI:-0.32 to 2.06),whereas combination therapy had significantly lower Greene scores(SMD=-0.24,95%CI:-0.44 to-0.04).No statistically significant difference was found between the groups in the occurrence of adverse reactions(odds ratio=0.90,95%CI:0.57-1.43).However,liver-soothing formulas did not affect estrogen levels in perimenopausal women.CONCLUSION Compared with placebo,conventional Western medicine,or other interventions,the monotherapy of liver-soothing formulas demonstrates superior efficacy in treating perimenopausal anxiety.When used as an adjuvant,they exert a synergistic effect in alleviating negative emotions and improving overall perimenopausal symptoms.
文摘Metabolic dysfunction-associated steatotic liver disease(MASLD)is an increasingly prevalent condition associated with hepatic complications and cardiovascular and renal events.Given its significant clinical impact,the development of new strategies for early diagnosis and treatment is essential to improve patient outcomes.Over the past decade,the integration of artificial intelligence(AI)into gastroenterology has led to transformative advancements in medical practice.AI represents a major step towards personalized medicine,offering the potential to enhance diagnostic accuracy,refine prognostic assessments,and optimize treatment strategies.Its applications are rapidly expanding.This article explores the emerging role of AI in the management of MASLD,emphasizing its ability to improve clinical prediction,enhance the diagnostic performance of imaging modalities,and support histopathological confirmation.Additionally,it examines the development of AI-guided personalized treatments,where lifestyle modifications and close monitoring play a pivotal role in achieving therapeutic success.
