El hemangioendotelioma epiteloide hepático (HEHE) es un tumor vascular raro de menor malignidad que el hemangiosarcoma. En los poco frecuentes casos unilobulares, puede indicarse hepatectomía parcial con riesgo de recurrencia agresiva; en enfermedad hepática extensa, incluso con compromiso extrahepático, el trasplante hepático ha resultado efectivo. Las metástasis son más frecuentes en pulmón,peritoneo, ganglios linfáticos, bazo y sistema nervioso. Se presenta el caso de un adolescente asintomático con HEHE con metástasis pulmonares y compromiso ganglionar abdominal que recibió trasplante hepático con evolución favorable.

Hepatic epithelioid hemangioendothelioma (HEHE) is a rare vascular tumor of less malignancy than hemangiosarcoma. In the rare unilobar cases, partial hepatectomy may be indicated with risk of aggressive recurrence; in extensive liver disease, even with extrahepatic involvement, liver transplantation has been performed successfully. Metastases are more common in the lung, peritoneum, lymph nodes, spleen, and nervous system. We present the case of an asymptomatic adolescent with HEHE with lung metastases and abdominal lymph node involvement who received a liver transplant with a favorable outcome.

With the breakthrough in surgical technology, pediatric liver transplantation (PLT) has achieved landmark development in China in recent years. In some high-volume centers, postoperative outcomes have even been comparable to the world-leading levels. However, postoperative infection remains a major factor affecting graft and recipient survivals. Thus, the Enhanced Recovery After Surgery Committee of the Chinese Research Hospital Association organized experts from multiple disciplines and formulated the consensus to improve the diagnosis, treatment and prevention of postoperative infections in PLT recipients. This consensus is based on the progress of domestic and international researches in this field and followed the principles of evidence-based medicine. It covers general and transplantation-specific infection, and is expected to provide reference for centers conducting or planning to conduct PLT.

RESUMEN La enfermedad de Caroli es una enfermedad infrecuente que requiere un alto índice de sospecha para su diagnóstico. Puede afectar un segmento hepático, un lóbulo o todo el hígado; suele generar episodios repetidos de colangitis. Existe una amplia gama de propuestas terapéuticas que oscilan desde el tratamiento médico hasta el trasplante de hígado. En este trabajo presentamos 3 casos, realizamos una revisión de la literatura y proponemos una ampliación de la clasificación de Alonso-Lej modificada por Todani que, a nuestra manera de ver, tiene implicaciones a la hora de seleccionar un tratamiento.

ABSTRACT Caroli's disease is a rare condition, and its diagnosis requires high level of suspicion. The disease may affect one segment, one lobe or the entire liver, and may result in repeated episodes of cholangitis. The disease can be managed using different therapeutic approaches ranging from medical treatment to liver transplantation. In this paper we report 3 cases with review of the literature and propose a modification of the classification by Alonso-Lej modified by Todani which we believe may be useful to guide treatment.

. (AU)Acute hepatic porphyrias (AHPs) are inborn errors of hemebiosynthesis and its most common and severe type is the acute intermittent porphyria (AIP). AIP is an hereditary autosomal dominant disease caused by accumulated porphobilinogen deaminase (PBG) and delta aminolevulin acid (ALA) products. The main symptoms are severe abdominal pain, neuromuscular and psychiatric disturbances, nausea, vomiting, encephalopathy, tachycardia, seizures, tremors and hypertension, that usually are manifested by acute crises. The treatment is based on clinical management and in cases which the patient's quality of life is affected liver transplantation (LT) may be an alternative choice. We report the case of a patient with AHP presenting recurrent crisis leading to chronic symptoms occurrence and poor quality of life with progressive unresponsiveness to hemin treatment. Patient was submitted to LT as curative therapy proposal, but patient still presents some clinical manifestations that may indicate the possibility of a secondary cause to explain persistence of her symptoms despite of biochemical normalization of ALA and PBG. (AU)

As porfirias hepáticas agudas (PHA) compreendem um grupo de porfirias que apresentam erros inatos na biossíntese do grupo heme, sendo a mais severa e o tipo mais comum da PHA, a porfiria aguda intermitente (PAI). A PAI é uma doença autossômica dominante causada pelo acúmulo dos produtos porfobilinogênio deaminase (PBG) e ácido delta-aminolevulínico (ALA). Os principais sintomas são dor abdominal intensa, distúrbios neuromusculares e psiquiátricos, náuseas, vômitos, encefalopatia, taquicardia, febre, tremores e hipertensão, os quais normalmente são manifestados durante as crises agudas. O tratamento é baseado no manejo clínico de todos pacientes durante a crise. Para os casos em que a qualidade de vida do paciente é afetada negativamente, a terapêutica de transplante hepático poderá ser indicada. O objetivo do relato de caso é introduzir o tratamento de uma paciente com recorrentes crises agudas de porfiria e danos em sua qualidade de vida. Uma vez que a paciente não apresentou melhora após tratamento com hematina, foi submetida ao transplante hepático visando a cura da doença. Após o transplante, a paciente ainda apresentou alguns sintomas clínicos, necessitando reformular uma segunda hipótese para explicar a persistência de tais sintomas apesar da normalização dos níveis de ALA e PBG.

ABSTRACT BACKGROUND: Immunosuppressive drugs have important role in transplant of solid grafts, it aim avoid episodes of acute and chronic rejection and improving graft survival and patient survival. In Brazil, in 2016, liver transplantation was the third most frequent, with 1,880 transplants performed, of which 150 in Rio Grande do Sul. Several studies evaluated the association between variability in blood levels of immunosuppressive tacrolimus and late acute cellular graft rejection. OBJECTIVE: To investigate the association of tacrolimus blood levels with clinical outcomes late acute cellular rejection, death, patient survival and graft survival in patients undergoing liver transplantation. METHODS: This is a retrospective longitudinal study including patients submitted to adult liver transplantation by the Liver Transplantation Group in the Santa Casa de Misericórdia Hospital of Porto Alegre, from January 2006 to January 2013, and who used tacrolimus as immunosuppressive therapy. RESULTS: Of the 127 patients included in the study, the majority were male (70.1%), 52-60 years old (33.9%) at the transplant. The most frequent causes of liver transplantation in this series were hepatitis C virus and hepatocellular carcinoma (24.4%) and alcohol (15.7%). Thirteen patients had late acute cellular rejection (10.2%); of these, three had two episodes. Regarding severity classification, seven patients had mild late acute cellular rejection. The mean time of rejection after liver transplantation was 14 months (ranging from 8 to 33 months). Overall survival was 8.98 years. Regarding tacrolimus blood levels, 52 patients with a variation ≥2 standard deviations were identified. Of these patients, eight had rejection; however, the association was not significant (P=0.146). A significant association was found between variation ≥2 standard deviations in tacrolimus blood levels and death (P=0.023) and survival (P=0.019). Regarding 5-year follow-up of graft survival, being two standard deviations above increases by 2.26 times the risk of transplanted graft loss, and for each unit of increase of standard deviation of tacrolimus blood levels there is a two-fold increase in the risk of graft loss in 5 years. CONCLUSION: Increased risk of graft loss associated with increased standard deviations of tacrolimus blood levels may indicate the need for more rigorous and prospective monitoring of tacrolimus blood levels.

RESUMO CONTEXTO: Os imunossupressores desempenham importante papel no transplante de órgãos sólidos, com o objetivo de evitar a rejeição aguda e crônica, aumentando o tempo de sobrevida do órgão e do paciente. No Brasil, em 2016, o transplante de fígado foi o 3° mais frequente, com um número de 1.880 transplantes, sendo 150 realizados no Rio Grande do Sul. OBJETIVO: Investigar a associação da variação dos níveis sanguíneos de tacrolimo com os desfechos clínicos, rejeição celular aguda tardia, óbito, sobrevida de paciente e enxerto em pacientes submetidos ao transplante hepático. MÉTODOS: Trata-se de um estudo longitudinal retrospectivo, no qual foram incluídos os pacientes submetidos ao transplante hepático adulto pelo grupo de transplante hepático na Irmandade Santa Casa de Misericórdia de Porto Alegre, no período de janeiro de 2006 a janeiro de 2013, e que fizeram o uso de tacrolimo como terapia imunossupressora. RESULTADOS: Dos 127 pacientes incluídos no estudo, a maioria era do gênero masculino (70,1%), caucasiana (86,4%), com idade entre 52 e 60 anos (33,9%). As associações de causas mais frequentes para transplante hepático foram vírus da hepatite C, carcinoma hepatocelular (24,4%) e álcool (15,7%). Um total de treze pacientes apresentaram rejeição celular aguda tardia (10,2%); destes, três tiveram dois episódios. O tempo médio de rejeição após o transplante hepático foi de 14 meses, variando de 8 a 33 meses. A sobrevida global foi de 8,98 anos. Em relação aos níveis sanguíneos de tacrolimo, foram identificados 52 pacientes com uma variação maior ou igual a dois desvios-padrão. Destes pacientes, oito tiveram rejeição, contudo, a associação não foi significativa (P=0,146). Foi encontrada uma associação significativa entre a variação maior ou igual a dois desvios-padrão nos níveis sanguíneos de tacrolimo com óbito (P=0,023) e sobrevida (P=0,019). Em relação ao acompanhamento de sobrevida do enxerto em cinco anos, estar dois desvios-padrão acima aumenta em 2,26 vezes o risco de perda do enxerto transplantado, e a cada unidade de aumento de desvio-padrão dos níveis sanguíneos de tacrolimo há um aumento de duas vezes no risco de perda do enxerto transplantado em 5 anos. CONCLUSÃO: O aumento do risco da perda do enxerto associado ao aumento da variação dos níveis sanguíneos de tacrolimo pode indicar a necessidade do acompanhamento mais rigoroso e prospectivo dos níveis sanguíneos de tacrolimo.

Abstract The aim of this study was to determine the incidence of preservation fluids (PF) bacterial positive cultures, identify the germs involved, determine their correlation with infections in recipients during the postoperative period and compare outcomes in terms of morbidity, hospital stay and both patient and graft survival. We describe incidence and etiology of germs developed in PF cultures in our series and evaluate its impact on recipients. A prospective study in deceased donor liver transplants (LT) recipients was carried out from January 2014 to December 2017. Back table PF cultures were analized considering positive the development of any germs and negative to no signs of growth after 5 days. PF were classified as contamination or pathogens. Targeted antibiotic therapy was administered in the last ones. Recipients were divided in: PF (-) and PF(+). Recipients infections related to positive PF were analyzed. These were identified as "direct correlation" when the same germ grew up in PF. Hospital stay and 30 days follow up were compared. Eighty-eight patients PFs were included, 38% (33) had positive cultures, 28 (85%) of these were considered contamination and only 5 as pathogens. We found no differences in postoperative infections (p 0.840), ICU and total hospital stay (p 0.374 and 0.427) between both groups. Postoperative infections and hospital stay seem not to be influenced by PF cultures positivity. Treatment of isolated pathogens could have prevented infections, therefore, those groups that perform PF cultures should consider treatment in these cases and conclude prophylaxis when PF is negative or contaminated.

Resumen Las infecciones bacterianas son frecuentes en pacientes sometidos a trasplante hepático. Describimos la incidencia y etiología de los cultivos de líquidos de preservación (LP) positivos en nuestra serie y analizamos su importancia clínica. Se trata de un trabajo prospectivo de pacientes trasplantados hepáticos, entre enero 2014 a diciembre 2017. Se analizaron muestras de LP tomadas al finalizar la mesa de banco, considerándose positivo el desarrollo de cualquier germen y negativo la ausencia del mismo luego de 5 días. Los LP positivos se clasificaron en: con contaminantes y con patógenos. Los pacientes con LP patógenos recibieron tratamiento antibiótico de acuerdo al antibiograma. Los pacientes fueron divididos en dos grupos: con LP + y LP-. Las infecciones relacionadas a los LP fueron analizadas. Se consideró "correlación directa" cuando el mismo germen desarrolló en el LP y en el recipiente. Se comparó estadía hospitalaria en ambos grupos. Se incluyeron 88 pacientes, 38% (33) presentaron LP+, de los que el 85% (28) fueron por contaminación y 5 por pa tógenos. No se hallaron diferencias significativas en infecciones postoperatorias (p 0.840) y estadía hospitalaria (p 0.427) entre ellos. No hubo casos de "correlación directa". Las infecciones postoperatorias y la estadía hospitalaria de los pacientes no parecen estar influidas por la positividad de los cultivos de LP. El tratamiento dirigido a los gérmenes aislados como patógenos pudo prevenir infecciones, por lo tanto, los grupos que realizan cultivos de rutina deberían considerar el tratamiento en estos casos y finalizar la profilaxis cuando el LP sea negativo o contaminado.

Abstract Paracoccidioidomycosis is an endemic systemic mycosis caused by Paracoccidioides brasiliensis complex and P. lutzii. It is a rare disease in non-HIV-induced immunosuppressed individuals. In organ transplant recipients, it is more frequently associated with immunosuppression after kidney transplantation. In a liver transplant patient, only one case has been published in the literature to date. The present report comprises the case of a 47-year-old female patient with disseminated skin lesions associated with signs and symptoms of systemic involvement of paracoccidioidomycosis that manifested one year after liver transplantation and under an immunosuppression regimen with tacrolimus and mycophenolate mofetil.

ABSTRACT BACKGROUND: The nature of liver disease, the evolutionary course and duration of liver diseases, as well as the degree of severity and disability can trigger multiple outcomes with repercussions on neuromotor acquisition and development. OBJECTIVE: To systematically review and conduct a meta-analysis to evaluate the effects of liver disease on the neuropsychomotor development of children and adolescents with their native livers and those who underwent liver transplantation. METHODS: Observational studies published since the early 1980s until June 2019 were sought in the PubMed and Scopus databases. An α value of 0.05 was considered significant. The statistical heterogeneity of the treatment effect between the studies was assessed by the Cochran's Q test and the I2 inconsistency test, in which values above 25 and 50% were considered indicative of moderate and high heterogeneity, respectively. Analyses were performed with Review Manager 5.3. RESULTS: Twenty-five studies met the eligibility criteria, including 909 children and adolescents with liver disease. Meta-analyses showed deficits in total IQ -0.41 (95%CI: -0.51 to -0.32; N: 9,973), verbal IQ -0.38 (95%CI: -0.57 to -0.18; N: 10,284) and receptive language -0.85 (95%CI: -1.16 to -0.53; N: 921) in liver transplantation, and those with native livers who had symptoms early had total and verbal IQ scores (85±8.8; 86.3±10.6 respectively) lower than the scores of those with late manifestations (99.5±13.8; 96.2±9.2). Gross motor skill was reduced -46.29 (95%CI: -81.55 to -11.03; N: 3,746). CONCLUSION: Acute or chronic liver disease can cause declines in cognitive, motor and language functions. Although the scores improve after liver transplantation, children remain below average when compared to healthy children.

RESUMO CONTEXTO: A natureza da doença hepática, curso evolutivo e duração das hepatopatias, bem como grau de severidade e incapacidade podem desencadear desfechos múltiplos e com repercussões na aquisição e desenvolvimento neuromotores. OBJETIVO: Revisar sistematicamente e avaliar por meta-análise os efeitos da doença hepática sobre o desenvolvimento neuropsicomotor de crianças e adolescentes com seus fígados nativos e aquelas que realizaram transplante hepático. MÉTODOS: As buscas foram realizadas nas bases de dados PubMed e periódicos Scopus desde as primeiras publicações na década de 1980 até junho de 2019, de estudos observacionais. Um valor de 0,05 foi considerado significativo. A heterogeneidade estatística do efeito do tratamento entre os estudos foi avaliada pelo teste Q de Cochran e o teste de inconsistência I2, no qual valores acima de 25 e 50% foram considerados indicativos de heterogeneidade moderada e alta, respectivamente. As análises foram realizadas com o Review Manager 5.3. RESULTADOS Vinte e cinco estudos preencheram os critérios de elegibilidade, incluindo 909 crianças e adolescentes com doenças hepáticas. As meta-análises mostraram déficits QI total -0,41 (IC 95%: -0,51 até -0,32; N: 9.973), QI verbal -0,38 (IC 95%; -0,57 até -0,18; N: 10.284) e linguagem receptiva -0,85 IC 95%: -1,16 até -0,53; N: 921) nos transplantes hepáticos e as com fígados nativos que apresentaram sintomas precocemente tinham escores de QI total e verbal (85±8,8; 86,3±10,6 respectivamente) menores do que aquelas com manifestações tardias (99,5±13,8; 96,2±9,2). Habilidade motora grossa apresentou-se reduzida -46,29 (IC 95%: -81,55 até -11,03; N: 3.746). CONCLUSÃO: A doença hepática aguda ou crônica pode determinar declínios nas funções cognitivas, motoras e de linguagem. Muito embora, os escores melhorem após transplante hepático, as crianças continuam abaixo da média quando comparadas às crianças sadias.

O objetivo deste estudo foi evidenciar e discutir as principais alterações hidroeletrolíticas em pessoas com cirrose. Trata-se de uma revisão integrativa, de natureza qualitativa. Os artigos foram selecionados por meio da plataforma Medical Literature Analysis and Retrievel System Online. Os principais achados identificados a partir dos artigos selecionados foram a ocorrência de hiponatremia, o mau prognóstico diante da presença de distúrbios hidroeletrolíticos em relação à sobrevida em pessoas com cirrose e a importância da albumina. Indivíduos com cirrose são suscetíveis ao desenvolvimento de distúrbios hidroeletrolíticos devido às mudanças fisiopatológicas da doença e às condições clínicas apresentadas. A hiponatremia e a hipocalemia são os mais recorrentes, destacando, porém, a necessidade de atenção aos demais distúrbios. (AU)

The objective of this study was to show and discuss the main hydroelectrolytic alterations in cirrhotic patients. This is an integrative review, a qualitative study, in which articles were selected at the Medical literature Analysis and Retrieval System Online. The main findings identified in the articles selected were the occurrence of hyponatremia, the poor prognostic, due to the presence of hydroelectrolytic disorders, regarding cirrhotic individuals survival and the importance of albumin. Individuals with cirrhosis are susceptible to the development of hydroelectrolytic disorders due to the pathophysiological alterations of the disease and because of the clinical status presented. Hyponatremia and hypokalemia are the most recurrent, but attention shall be given to the other disorders too. (AU)

ABSTRACT BACKGROUND: The use of immunosuppressive drugs after liver transplantation (LT) is associated with the development of systemic arterial hypertension (SAH), in addition to other comorbidities of metabolic syndrome. OBJECTIVE: Therefore, the purpose of this study was to analyze the time after use immunosuppressive drugs the patient progresses to SAH, as well as to identify its prevalence and the factors that may be correlated to it. METHODS: A retrospective and longitudinal study was conducted, based on the analysis of medical records of 72 normotensive patients, attended in the transplant unit of a university hospital, between 2016 and 2019. RESULTS: It was observed, on average, 9±6.98 months after immunosuppressive use, the patients were diagnosed with hypertension, and the prevalence of transplanted patients who evolved to SAH in this study was 59.64% (41 patients). In addition, there was a correlation between serum dosage of tacrolimus and the development of SAH (P=0.0067), which shows that tacrolimus has a significant role in the development of SAH. Finally, it was noticed that the development of post-transplantation hypertension indicates a higher risk of the patient presenting the other parameters of metabolic syndrome, as well as a higher impairment in its renal function (P=0.0061). CONCLUSION: This study shows that the patients evolved to SAH in an average of 9±6.98 months after immunosuppressive drug use. We have also found high prevalence of systemic arterial hypertension (59.64%) in patients after liver transplantation, who used calcineurin inhibitors, especially when associated with the use of tacrolimus.

RESUMO CONTEXTO: O uso de imunossupressores pós-transplante de fígado (TF) está associado ao desenvolvimento de hipertensão arterial sistêmica (HAS), além de outras alterações da síndrome metabólica. OBJETIVO: Sendo assim, o objetivo deste estudo foi analisar a partir de quando tempo após o uso do imunossupressor o paciente evolui para HAS, assim como, identificar a sua prevalência e outros fatores que podem estar relacionados, como injuria renal. MÉTODOS: Realizou-se um estudo retrospectivo, longitudinal, baseado em análise de 72 prontuários de pacientes, atendidos na unidade de transplante de um hospital universitário, que não apresentavam hipertensão arterial prévia, entre período de 2016 a 2019. RESULTADOS: Observou-se que, em média, 9±6,98 meses após uso do imunossupressor, os pacientes foram diagnosticados com hipertensão arterial sistêmica, sendo que a prevalência de pacientes transplantados que evoluíram para HAS, neste estudo, foi de 59,64% (41 pacientes). Além disso, verificou-se uma correlação entre a dosagem sérica de tacrolimus e o desenvolvimento de HAS (P=0,0067), o que evidencia que o tacrolimus tem uma atuação significativa no desenvolvimento da hipertensão arterial sistêmica. Por fim, percebeu-se que o desenvolvimento de HAS pós-transplante indica um maior risco de paciente apresentar os outros parâmetros da síndrome metabólica, como também maior prejuízo na sua função renal (P=0,0061). CONCLUSÃO: Este estudo mostra que os pacientes evoluíram para HAS em média 9±6,98 meses após o início do uso do imunossupressor. Verificou-se também alta prevalência de hipertensão arterial sistêmica (59,64%) em pacientes pós-transplante de fígado, que usavam inibidores de calcineurina, principalmente, quando associado ao uso de tacrolimus.

ABSTRACT BACKGROUND: Receptors of living donor liver transplantation (LDLT) have higher rate of postoperative biliary and vascular complications that may reduce posttransplant quality of life (QOL) due to the need of invasive and repetitive treatments. OBJECTIVE: The purpose of our study is to assess the various aspects of QOL of receptors undergoing LDLT after 10 years of transplantation and to identify potential factors that might be associated with impaired QOL. METHODS: Data of all patients with more than 10 years of LDLT were retrospectively evaluated. Patients were interviewed through a quality of life questionnaire (SF-36). RESULTS: From a total of 440 LT performed in 17 years (from September 1991 through December 2008), 78 patients underwent LDLT, of which 27 were alive and 25 answered completely the questionnaire. There were 17 (68%) men and 8 (32%) women, with a mean age of 38.6±18.5 years at the time of transplantation and mean follow up time of 15.1±1.9 years. The average MELD was 16.4±4.9 and the main indication for LT was hepatic cirrhosis caused by hepatitis B virus (32%). When compared to the general po­pulation, LDLT patients had lower mental health score (66.4 vs 74.5, P=0.0093) and higher vitality score (87.8 vs 71.9, P<0.001), functional aspects (94.6 vs 75.5, P=0.002), social aspects (93 vs 83.9, P=0.005), physical aspects (92 vs 77.5, P=0.006), and emotional aspects (97.33 vs 81.7, P<0.001). General health status (73.28 vs 70.2, P=0.074) and pain (78.72 vs 76.7, P=0.672) scores were similar in both groups. CONCLUSION: It is concluded that the various aspects LDLT recipients' QOF are similar to those of the general population more than a decade after the transplant, except for the mental health domain which is lower.

RESUMO CONTEXTO: Receptores de transplante hepático inter-vivo (THIV) apresentam elevada taxa de complicações biliares e vasculares pós-operatórias que podem reduzir a qualidade de vida (QV) devido à necessidade de tratamentos invasivos e repetitivos. OBJETIVO: O objetivo deste estudo é avaliar os vários aspectos da qualidade de vida dos pacientes submetidos a THIV após 10 anos de transplante e identificar possíveis fatores que possam estar associados à diminuição da QV. MÉTODOS: Os dados de todos os pacientes com mais de 10 anos de THIV foram avaliados retrospectivamente. Os pacientes foram entrevistados por meio de um questionário de qualidade de vida (SF-36). RESULTADOS: Do total de 440 transplantes hepáticos realizados em 17 anos (setembro de 1991 a dezembro de 2008), 78 pacientes foram submetidos a THIV, dos quais 27 estavam vivos e 25 responderam completamente ao questionário. Destes, 17 (68%) homens e 8 (32%) mulheres, com idade média de 38,6±18,5 anos no momento do transplante e tempo médio de acompanhamento de 15,1±1,9 anos. O MELD médio foi de 16,4±4,9 e a principal indicação para o transplante hepático foi cirrose hepática causada pelo vírus da hepatite B, 32%. Quando comparado com a população geral, os pacientes submetidos a THIV apresentaram menor escore de saúde mental (66,4 vs 74,5; P=0,0093) e escores mais altos de vitalidade (87,8 vs 71,9; P<0,001), aspectos funcionais (94,6 vs 75,5; P=0,002), aspectos sociais (93 vs 83,9; P=0,005), aspectos físicos (92 vs 77,5; P=0,006), e aspectos emocionais (97,33 vs 81,7; P<0,001). Os escores do estado geral de saúde (73,28 vs 70,2; P=0,074) e de dor (78,72 vs 76,7; P=0,672) eram similares nos dois grupos. CONCLUSÃO: Conclui-se que os vários aspectos da QV dos receptores de transplante hepático inter-vivo são semelhantes aos da população geral mais de uma década após o transplante, exceto o domínio da saúde mental que é menor.

Introducción: La historia de la cirugía del hígado abarca 28 siglos, lo que ha permitido su evolución desde considerar al hígado como un órgano intocable hasta realizar hepatectomías complejas y trasplante hepático. Esta investigación representa el balance de 10 años en la actividad de un grupo de cirugía hepatobiliar. Objetivo: Caracterizar el tratamiento quirúrgico de los tumores hepáticos sólidos en el Centro de Investigaciones Médico-Quirúrgicas entre los años 2009 y 2019. Métodos: Se realizó un estudio de tipo observacional, descriptivo, longitudinal y retrospectivo en el que se analizaron 129 pacientes que fueron tributarios de tratamiento quirúrgico. Resultados: Los tumores malignos representaron el 73 por ciento del total, dentro de este grupo se destacan los metastásicos con 50 casos. La morbilidad de esta cirugía fue del 13 por ciento y la mortalidad operatoria del 2 por ciento. La causa de muerte identificada fue el shock séptico por peritonitis generalizada. Conclusiones: Los tumores malignos fueron los más frecuentes. Se presentó una baja morbilidad encontrándose el derrame pleural como la complicación más usual. Existe una mortalidad acorde a los valores reportados para este tipo de cirugía(AU)

Introduction: The history of liver surgery covers twenty-eight centuries, which has allowed its evolution from considering the liver as an untouchable organ to performing complex hepatectomies and hepatic transplantation. This research describes the ten years' balance in the activity developed by a hepatobiliary surgery team. Objective: To characterize the surgical management of solid hepatic tumors in the Center for Medical-Surgical Research between 2009 and 2019. Methods: An observational, descriptive, longitudinal and retrospective study was carried out, for which 129 patients who underwent surgical treatment were analyzed. Results: Malignant tumors accounted for 73 percent of the total; within this group, metastatic tumors stand out, accounting for fifty cases. Morbidity of this surgery type was 13 percent, while operative mortality was 2 percent. The cause of death identified was septic shock due to generalized peritonitis. Conclusions: Malignant tumors were the most frequent. There was low morbidity, with pleural effusion as the most common complication. Mortality is consistent with the values reported for this type of surgery(AU)

This paper introduced a liver normothermic machine perfusion repair and assessment system. This system consists of a liver normothermic machine perfusion device, a fluorescence imaging system and a tissue oxygen detector. The normothermic machine perfusion device can continuously perfuse the donor liver and monitor and control the perfusion parameters in real time. The fluorescence imaging system can detect the indocyanine green metabolized by the liver to evaluate the microcirculation and the metabolism function of hepatocytes. The tissue oxygen detector can monitor the change of oxygen partial pressure of liver tissue in real time to evaluate the state of cell oxygen consumption.

To investigate the postoperative serum triglyceride (TG) levels in predicting the risk of new-onset diabetes mellitus (NODM) in patients following allogeneic liver transplantation. One hundred and forty three patients undergoing allogeneic liver transplantation in Shanghai General Hospital from July 2007 to July 2014 were enrolled in this study. The NODM developed in 33 patients after liver transplantation. The curve of dynamic TG levels in the early period after liver transplantation was generated. Independent risk factors of NODM were determined by univariate and multivariant logistic regression analyses. The clinical value of TG in predicting NODM was analyzed by area under the ROC curve (AUC). Serum TG levels were gradually rising in the first week and then reached the plateau phase (stable TG, sTG) in patients after surgery. The sTG in NODM group were significantly higher than that in non-NODM group (=-2.31, <0.05). Glucocorticoid therapy (=4.054, <0.01), FK506 drug concentration in the first week after operation (=3.482, <0.05) and sTG (=3.156, <0.05) were independent risk factors of NODM. ROC curve analysis showed that the AUC of sTG in predicting NODM was 0.72. TG shows a gradual recovery process in the early period after liver transplantation, and the higher TG level in stable phase may significantly increase the risk of NODM in patients.

Pediatric liver transplantation (PLT) is an effective strategy of treating various acute or chronic end-stage liver diseases and inherited metabolic diseases in children.PLT has been applied in many transplant centers nationwide and has achieved satisfactory results.However,the development of transplant centers is uneven,and there is a lack of consensus and standards within the industry.In order to reduce post-operative complications,accelerate post-operative recovery,and improve the short-and long-term quality of life of children,the Enhanced Recovery After Surgery Committee of Chinese Research Hospital Association organized multidisciplinary experts to summarize the progress of domestic and international research,and formulated a perioperative consensus on PLT based on the principles of evidence-based medicine.The consensus provides recommendations for perioperative PLT from three aspects:preoperative assessment and preparation,intraoperative management and postoperative management,in order to provide reference guidelines for centers that are conducting or preparing to conduct PLT.

INTRODUCTION@#Hepatic artery reconstruction is a critical aspect of liver transplantation. The microsurgeon faces several challenges when reconstructing the hepatic artery-the donor hepatic artery stalk is short and often a poor match for the usually hypertrophic recipient vessels. Previous inflammation impedes vessel dissection, and recipient vessels have a tendency to delaminate with manipulation. We review 51 consecutive liver transplantations to highlight these problems and propose strategies for a successful reconstruction of the hepatic artery.@*METHODS@#A prospective study involving all adult patients undergoing liver transplantation at the Singapore General Hospital from January 2015 to December 2018 was undertaken. All hepatic artery anastomoses were performed by 2 microsurgeons at 10x magnification. Patients were started on a standard immunosuppressive regimen. Postoperative ultrasound scans on days 1, 3, 5, 7, 9 and 14 were used to confirm arterial patency.@*RESULTS@#There were 51 patients who underwent liver transplantation during the study period. Of this number, 31 patients received deceased donor grafts and 20 received living donor grafts. A total of 61 anastomoses were performed (5 dual anastomosis, 4 radial artery interposition grafts) with 1 case of hepatic artery thrombosis that was successfully salvaged. The mean (range) postoperative resistive index and hepatic artery peak systolic velocity were 0.69 (0.68-0.69) and 1.0m/s (0.88-1.10m/s), respectively.@*CONCLUSION@#Hepatic artery thrombosis after liver transplantation is poorly tolerated. The challenges of hepatic artery reconstruction in liver transplantation are related to vessel quality and length. The use of microsurgical technique, appropriate recipient vessel selection, minimisation of vessel manipulation with modified instruments, variation in anastomosis techniques, and use of radial artery interpositional grafts are useful strategies to maximise the chances of success.
