ABSTRACT BACKGROUND: Hepatic retransplantation is associated with higher morbidity and mortality when compared to primary transplantation. Given the scarcity of organs and the need for efficient ...allocation, evaluating parameters that can predict post-retransplant survival is crucial. AIMS: This study aimed to analyze prognostic scores and outcomes of hepatic retransplantation. METHODS: Data on primary transplants and retransplants carried out in the state of Paraná in 2019 and 2020 were analyzed. The two groups were compared based on 30-day survival and the main prognostic scores of the donor and recipient, namely Model for End-Stage Liver Disease (MELD), MELD-albumin (MELD-a), Donor MELD (D-MELD), Survival Outcomes Following Liver Transplantation (SOFT), Preallocation Score to Predict Survival Outcomes Following Liver Transplantation (P-SOFT), and Balance of Risk (BAR). RESULTS: A total of 425 primary transplants and 30 retransplants were included in the study. The main etiology of hepatopathy in primary transplantation was ethylism (n=140; 31.0%), and the main reasons for retransplantation were primary graft dysfunction (n=10; 33.3%) and hepatic artery thrombosis (n=8; 26.2%). The 30-day survival rate was higher in primary transplants than in retransplants (80.5% vs. 36.7%, p=0.001). Prognostic scores were higher in retransplants than in primary transplants: MELD 30.6 vs. 20.7 (p=0.001); MELD-a 31.5 vs. 23.5 (p=0.001); D-MELD 1234.4 vs. 834.0 (p=0.034); SOFT 22.3 vs. 8.2 (p=0.001); P-SOFT 22.2 vs. 7.8 (p=0.001); and BAR 15.6 vs. 8.3 (p=0.001). No difference was found in terms of Donor Risk Index (DRI). CONCLUSIONS: Retransplants exhibited lower survival rates at 30 days, as predicted by prognostic scores, but unrelated to the donor’s condition.
RESUMO RACIONAL: O retransplante hepático está associado a maior morbimortalidade do que o transplante primário. Dada a escassez de órgãos e a necessidade de alocação eficiente, avaliar parâmetros que possam prever a sobrevida pós-retransmissão é crucial. OBJETIVOS: Analisar os resultados dos retransplantes hepáticos em relação aos principais escores prognósticos. MÉTODOS: Foram analisados os transplantes primários e os retransplantes realizados no Estado do Paraná nos anos de 2019 e 2020. Os dois grupos foram comparados em relação à sobrevida em 30 dias e aos principais escores prognósticos do doador e do receptor: Model for End-Stage Liver Disease (MELD), MELD-albumin (MELD-a), Donor MELD (D-MELD), Survival Outcomes Following Liver Transplantation (SOFT), Preallocation Score to Predict Survival Outcomes Following Liver Transplantation (P-SOFT) e Balance of Risk (BAR). RESULTADOS: Foram incluídos 425 transplantes primários e 30 retransplantes. A principal etiologia da hepatopatia no transplante primário dos pacientes retransplantados foi o etilismo (n=140; 31,0%), e os principais motivos para os retransplantes foram o não funcionamento primário do enxerto (n=10; 33,3%) e a trombose da artéria hepática (n=8; 26,2%). A sobrevida em 30 dias foi maior nos transplantes primários em relação aos retransplantes (80,5% vs 36,7%; p=0,001). Os escores prognósticos foram mais elevados nos retransplantes em relação aos transplantes primários: MELD 30,6 vs 20,7 (p=0,001); MELD-a 31,5 vs 23,5 (p=0,001); D-MELD 1234,4 vs 834,0 (p=0,034); SOFT 22,3 vs 8,2 (p=0,001); P-SOFT 22,2 vs 7,8 (p=0,001); e BAR 15,6 vs 8,3 (p=0,001). Não foi observada diferença em relação ao Índice de Risco do Doador. CONCLUSÕES: Os retransplantes apresentam menor sobrevida em 30 dias, prevista nos escores prognósticos, porém sem relação com a qualidade dos doadores.
ABSTRACT BACKGROUND: The prevalence of primary sclerosing cholangitis (PSC) in the general population has not yet been clearly established. The management of PSC should focus on delaying the ...progression of the disease and restraining its complications. The only curative therapy for the disease remains liver transplantation (LT). PSC is currently the fifth most common indication for LT and corresponds to 5% of all LT indications in adults. AIMS: Our objective is to evaluate the indications and outcomes of PSC patients undergoing LT in three liver transplantation centers in southern Brazil – Hospital Santa Isabel in Blumenau, Santa Catarina state, and Hospital das Clínicas and Hospital Nossa Senhora das Graças, in Curitiba, Parana state). METHODS: This is a longitudinal observational study of patients with PSC who underwent LT in three major Brazilian medical centers. Electronic medical records and study protocols of all patients subjected to LT from January 2011 to December 2021 were retrospectively reviewed. RESULTS: Of the 1,362 transplants performed in the three medical centers, 37 were due to PSC. Recurrence of PSC occurred in three patients (8.1%) in 3.0±2.4 years (range, 1–4 years). The 1-year and 5-year survival rates after the first LT were 83.8 and 80.6%, respectively. The 1-year and 5-year graft survival rates were, respectively, 83.8 and 74.8%. CONCLUSIONS: Our experience with LT in patients with PSC demonstrated good patient and graft survival results. Most deaths were due to common factors in patients undergoing LT.
RESUMO RACIONAL: A prevalência de colangite esclerosante primária (CEP) na população em geral ainda não foi claramente estabelecida. O manejo da CEP deve se concentrar em retardar a progressão da doença e gerenciar suas complicações. A única terapia curativa para a doença continua sendo o transplante hepático (TH). A CEP é atualmente a 5ª indicação mais comum de TH e corresponde a 5% de todas as indicações de TH em adultos OBJETIVOS: O nosso objetivo é avaliar as indicações e os resultados do transplante de fígado em pacientes com CEP submetidos a TH em três centros de transplante de fígado no sul do Brasil (Hospital Santa Isabel, Blumenau, Santa Catarina; Hospital das Clínicas, Curitiba, Paraná; e Hospital Nossa Senhora das Graças, Curitiba, Paraná). MÉTODOS: Este é um estudo observacional longitudinal de pacientes com colangite esclerosante primária que foram submetidos a transplante hepático em três grandes centros médicos brasileiros. Os prontuários eletrônicos de todos os pacientes submetidos a TH de Janeiro de 2011 a Dezembro de 2021, foram avaliados retrospectivamente. RESULTADOS: De um total de 1.362 transplantes realizados nos três centros médicos, 37 eram devidos à CEP. A recorrência de CEP ocorreu em 3 pacientes (8,1%) em 3±2,4 anos (intervalo, 1–4 anos). A taxa de sobrevida de 1 ano e 5 anos após o 1° TH foi respectivamente de 83,8 e 80,6%. As taxas de sobrevida dos enxertos em 1 ano e 5 anos foram, respectivamente, 83,8 e 74,8%. CONCLUSÕES: A nossa experiência com TH em pacientes com CEP demonstrou bons resultados de sobrevida dos pacientes e dos enxertos. A maioria dos óbitos ocorreu devido a fatores comuns em pacientes submetidos a TH.
ABSTRACT Acute cholecystitis (AC) is an acute inflammatory process of the gallbladder that may be associated with potentially severe complications, such as empyema, gangrene, perforation of the ...gallbladder, and sepsis. The gold standard treatment for AC is laparoscopic cholecystectomy. However, for a small group of AC patients, the risk of laparoscopic cholecystectomy can be very high, mainly in the elderly with associated severe diseases. In these critically ill patients, percutaneous cholecystostomy or endoscopic ultrasound gallbladder drainage may be a temporary therapeutic option, a bridge to cholecystectomy. The objective of this Brazilian College of Digestive Surgery Position Paper is to present new advances in AC treatment in high-risk surgical patients to help surgeons, endoscopists, and physicians select the best treatment for their patients. The effectiveness, safety, advantages, disadvantages, and outcomes of each procedure are discussed. The main conclusions are: a) AC patients with elevated surgical risk must be preferably treated in tertiary hospitals where surgical, radiological, and endoscopic expertise and resources are available; b) The optimal treatment modality for high-surgical-risk patients should be individualized based on clinical conditions and available expertise; c) Laparoscopic cholecystectomy remains an excellent option of treatment, mainly in hospitals in which percutaneous or endoscopic gallbladder drainage is not available; d) Percutaneous cholecystostomy and endoscopic gallbladder drainage should be performed only in well-equipped hospitals with experienced interventional radiologist and/or endoscopist; e) Cholecystostomy catheter should be removed after resolution of AC. However, in patients who have no clinical condition to undergo cholecystectomy, the catheter may be maintained for a prolonged period or even definitively; f) If the cholecystostomy catheter is maintained for a long period of time several complications may occur, such as bleeding, bile leakage, obstruction, pain at the insertion site, accidental removal of the catheter, and recurrent AC; g) The ideal waiting time between cholecystostomy and cholecystectomy has not yet been established and ranges from immediately after clinical improvement to months. h) Long waiting periods between cholecystostomy and cholecystectomy may be associated with new episodes of acute cholecystitis, multiple hospital readmissions, and increased costs. Finally, when selecting the best treatment option other aspects should also be considered, such as costs, procedures available at the medical center, and the patient’s desire. The patient and his family should be fully informed about all treatment options, so they can help making the final decision.
RESUMO A colecistite aguda (CA) é um processo inflamatório agudo da vesícula biliar que pode estar associado a complicações potencialmente graves, como empiema, gangrena, perfuração da vesícula biliar e sepse. O tratamento padrão para a CA é a colecistectomia laparoscópica. No entanto, para um pequeno grupo de pacientes com CA, o risco de colecistectomia laparoscópica pode ser muito alto, principalmente em idosos com doenças graves associadas. Nestes pacientes críticos, a colecistectomia percutânea ou a drenagem endoscópica da vesícula biliar guiada por ultrassom podem ser uma opção terapêutica temporária, como ponte para a colecistectomia. O objetivo deste artigo de posicionamento do Colégio Brasileiro de Cirurgia Digestiva é apresentar novos avanços no tratamento da CA em pacientes cirúrgicos de alto risco, para auxiliar cirurgiões, endoscopistas e clínicos a selecionar o melhor tratamento para os seus pacientes. A eficácia, segurança, vantagens, desvantagens e resultados de cada procedimento são discutidos. As principais conclusões são: a) Pacientes com CA e risco cirúrgico elevado devem ser tratados preferencialmente em hospitais terciários onde a experiência e os recursos cirúrgicos, radiológicos e endoscópicos estão disponíveis. b) A modalidade de tratamento ideal para pacientes com elevado risco cirúrgico, deve ser individualizada, com base nas condições clínicas e na experiência disponível. c) A colecistectomia laparoscópica continua sendo uma excelente opção de tratamento, principalmente em hospitais em que a drenagem da vesícula biliar percutânea ou endoscópica não está disponível. d) A colecistostomia percutânea e a drenagem endoscópica da vesícula biliar devem ser realizadas apenas em hospitais bem equipados e com radiologista intervencionista e/ou endoscopista experientes. e) O cateter de colecistostomia deve ser removido após a resolução da CA. No entanto, em pacientes que não têm condição clínica para realizar colecistectomia, o cateter pode ser mantido por um período prolongado ou mesmo definitivamente. f) Se o cateter de colecistostomia for mantido por longo período de tempo podem ocorrer várias complicações, como sangramento, fístula biliar, obstrução, dor no local de inserção, remoção acidental do cateter e CA recorrente. g) O tempo de espera ideal entre a colecistostomia e a colecistectomia ainda não foi estabelecido, e vai desde imediatamente após a melhoria clínica, até meses após. h) Longos períodos de espera entre colecistostomia e colecistectomia podem estar associados a novos episódios de CA, múltiplas readmissões hospitalares e aumento dos custos. Finalmente, ao selecionar a melhor opção de tratamento, outros aspectos também devem ser considerados, como custos, disponibilidade dos procedimentos no centro médico e o desejo do paciente. O paciente e sua família devem ser completamente informados sobre todas as opções de tratamento, para que possam ajudar a tomar a decisão final.
•Lemierre syndrome is a rare complication of oropharyngeal infection.•The present report is the first report of Lemierre syndrome in a post–liver transplant patient.•Few studies reporting the ...occurrence of Lemierre syndrome in immunosuppressed patients as a result of visceral transplantation were identified.
Lemierre syndrome is a rare complication of oropharyngeal infection, especially acute pharyngotonsillitis, associated with septicemia and thrombophlebitis of the internal jugular vein (IJV). We present the case of a 52-year-old patient who underwent liver transplantation and returned with symptoms of pain, redness and left cervical bulging 1 month after surgery. After investigation, the diagnosis of septic thrombophlebitis of the IJV was made. The patient responded well to treatment with antibiotic therapy and full anticoagulation. To the best of our knowledge, the present report is the first report of Lemierre syndrome in a post–liver transplant patient.
ABSTRACT BACKGROUND: Patients listed for liver transplantation and hepatocellular carcinoma are considered priority on the waiting list, and this could overly favor them. AIM: This study aimed to ...evaluate the impact of this prioritization. METHODS: We analyzed the liver transplants performed in adults from 2011 to 2020 and divided into three groups: adjusted Model of End-Stage Liver Disease (MELD) score for hepatocellular carcinoma, other adjusted Model of End-Stage Liver Disease situations, and no adjusted Model of End-Stage Liver Disease. RESULTS: A total of 1,706 patients were included in the study, of which 70.2% were male. Alcoholism was the main etiology of cirrhosis (29.6%). Of the total, 305 patients were with hepatocellular carcinoma, 86 with other adjusted Model of End-Stage Liver Disease situations, and 1,315 with no adjusted Model of End-Stage Liver Disease. Patients with hepatocellular carcinoma were older (58.9 vs. 53.5 years). The predominant etiology of cirrhosis was viral hepatitis (60%). The findings showed that group with adjusted Model of End-Stage Liver Disease had lower physiological Model of End-Stage Liver Disease (10.9), higher adjusted Model of End-Stage Liver Disease (22.6), and longer waiting list time (131 vs. 110 days), as compared to the group with no adjusted Model of End-Stage Liver Disease. The total number of transplants and the proportion of patients transplanted for hepatocellular carcinoma increased from 2011 to 2020. There was a reduction in the proportion of patients with hepatocellular carcinoma and adjusted Model of End-Stage Liver Disease of 20 and there was an increase on waiting list time in this group. There was an increase in the proportion of those with adjusted Model of End-Stage Liver Disease of 24 and 29, but the waiting list time remained stable. CONCLUSION: Over the past decade, prioritization of hepatocellular carcinoma resulted in an increased proportion of transplanted patients in relation to those with no priority. It also increased waiting list time, requiring higher adjusted Model of End-Stage Liver Disease to transplant an organ.
RESUMO RACIONAL: Pacientes portadores de carcinoma hepatocelular com indicação de transplante hepático recebem prioridade na lista de espera e isso poderia favorecê-los demasiadamente. OBJETIVO: Avaliar o impacto dessa priorização. MÉTODOS: Foram analisados os transplantes hepáticos realizados de 2011 até 2020 no estado do Paraná, divididos em três grupos: portadores de carcinoma hepatocelular no modelo para doença hepática terminal (MELD) ajustado, outras situações no modelo para doença hepática terminal ajustado e sem o modelo para doença hepática terminal ajustado. RESULTADOS: Foram incluídos 1.706 pacientes, 70,2% do gênero masculino, a maioria portadores de cirrose alcoólica (29,6%): 305 com hepatocarcinoma, 86 com outras situações no modelo para doença hepática terminal ajustado e 1.315 sem o modelo para doença hepática terminal ajustado. Nos portadores de hepatocarcinoma, a idade média foi maior (58,9 vs 53,5 anos), a etiologia predominante da cirrose foram as hepatites virais (60%), apresentaram menor no modelo para doença hepática terminal fisiológico (10,9), maior no modelo para doença hepática terminal corrigido (22,6 vs 21,8) e maior tempo em lista de espera (131 vs 110 dias) quando comparados ao grupo sem o modelo para doença hepática terminal ajustado. O número de transplantes e a proporção de pacientes transplantados por hepatocarcinoma aumentou de 2011 até 2020. Houve redução da proporção dos portadores de hepatocarcinoma com o modelo para doença hepática terminal de 20 no decorrer da década e aumento do tempo em lista nesse grupo. Para os com modelo para doença hepática terminalde 24 e de 29, houve aumento na proporção e o tempo em lista permaneceu estável. CONCLUSÃO: A priorização do hepatocarcinoma conferiu maior modelo para doença hepática terminal e incremento na proporção de transplantes em relação aos sem prioridade. Também aumentou o tempo em lista de espera, necessitando maior modelo para doença hepática terminal corrigido para obtenção de um órgão.
Repair of inguinal hernia concomitant with cholecystectomy was rarely performed until more recently when laparoscopic herniorrhaphy gained more adepts. Although it is generally an attractive option ...for patients, simultaneous performance of both procedures has been questioned by the potential risk of complications related to mesh, mainly infection.
To evaluate a series of patients who underwent simultaneous laparoscopic inguinal hernia repair and cholecystectomy, with emphasis on the risk of complications related to the mesh, especially infection.
Fifty patients underwent simultaneous inguinal repair and cholecystectomy, both by laparoscopy, of which 46 met the inclusion criteria of this study.
In all, hernia repair was the first procedure performed. Forty-five (97,9%) were discharged within 24 h after surgery. Total mean cost of the two procedures performed separately ($2,562.45) was 43% higher than the mean cost of both operations done simultaneously ($1,785.11). Up to 30-day postoperative follow-up, seven (15.2%) presented minor complications. No patient required hospital re-admission, percutaneous drainage, antibiotic therapy or presented any other signs of mesh infection after three months. In long-term follow-up, mean of 47,1 months, 38 patients (82,6%) were revaluated. Three (7,8%) reported complications: hernia recurrence; chronic discomfort; reoperation due a non-reabsorbed seroma, one in each. However, none showed any mesh-related complication. Satisfaction questionnaire revealed that 36 (94,7%) were satisfied with the results of surgery. All of them stated that they would opt for simultaneous surgery again if necessary.
Combined laparoscopic inguinal hernia repair and cholecystectomy is a safe procedure, with no increase in mesh infection. In addition, it has important advantage of reducing hospital costs and increase patient' satisfaction.
Abstract
Gallbladder agenesis (GA) is a rare congenital anomaly with conflicting epidemiology described in the literature. When present, it is misinterpreted as cholelitiasis, a highly prevalent ...condition. Nevertheless, surgeons and radiologists must be aware of it since it can lead to unnecessary invasive procedures. Diagnosis of GA is challenging due to the anatomical structures that sometimes resemble a shrunken gallbladder. We report the case of a 55-year-old man with preoperative diagnosis of cholelitiasis and further intraoperative find of GA. Since cholecystectomy is one of the most common surgeries worldwide, it demonstrates how relevant this case is to emphasize the need to recognize this diagnosis and be aware of its management to avoid unnecessary surgery.
ABSTRACT Background: Median arcuate ligament syndrome(MALS) is a rare condition thatmay cause significant clinical manifestations, including abdominal pain and weight loss. Its diagnosis may be ...difficult and very often delayed. The laparoscopic approach became the standard treatment of MALS. Aim: To assess the outcome of laparoscopic treatment in patients with MALS. Method: The data of sixpatients with MALS who were subjected to laparoscopic sectioning of the median arcuate ligament were retrospectively reviewed.The following data were evaluated: age, gender, clinical and diagnostic tests findings, ASA score, operative findings and complications, postoperative complications and mortality, hospital stay duration, and hospital readmission.The diagnosis of MALS was established by CT angiography and/or MR angiography. Results: There were four (66.7%) women and two (33.3%) men aged from 32 to 60 years. The main symptoms were epigastric pain (100%) and weight loss (66.7%). The findings of high-grade stenosis of the proximal celiac axis and poststenotic dilation confirmed on angiography confirmed the diagnosis in all patients. Surgical procedure was uneventful in all patients. The only postoperative complication was urinary retention that occurred in a male. At three-month follow-up, all patients were asymptomatic. Conclusion: Laparoscopic treatment of MALS is safe and effective in relieving the clinical manifestations of patients.
RESUMO Racional: A síndrome do ligamento arqueado mediano (SLAM) é condição rara que pode causar manifestações clínicas significativas, incluindo dor abdominal e perda de peso. Seu diagnóstico pode ser difícil e muitas vezes estabelecido tardiamente. A abordagem laparoscópica tornou-se o tratamento padrão para ela. Objetivo: Avaliar o resultado do tratamento laparoscópico em pacientes com SLAM. Método: Os dados de seis pacientes com SLAM submetidos a ressecção laparoscópica do ligamento arqueado mediano foram revisados retrospectivamente. Os seguintes dados avaliados foram: idade, gênero, resultados dosexames clínicos e complementares, escore ASA, achados e complicações operatórias, complicações e mortalidade pós-operatórias, tempo de internação e readmissão hospitalar. O diagnóstico de SLAM foi estabelecido por angiotomografia e/ou angiorressonância. Resultados: Havia quatro (66,7%) mulheres e dois (33,3%) homens com idades entre 32 e 60 anos. Os principais sintomas foram dor epigástrica (100%) e perda de peso (66,7%). Os achados de estenose de alto grau do tronco celíaco proximal e dilatação pós-estenótica observados na angiografia confirmaram o diagnóstico em todos os pacientes. O procedimento cirúrgico transcorreu sem intercorrências em todos os pacientes. A única complicação pós-operatória foi retenção urinária, que ocorreu em um homem. No seguimento de três meses, todos os pacientes estavam assintomáticos. Conclusão: O tratamento laparoscópico da SLAM é seguro e eficaz no alívio das manifestações clínicas dos pacientes.
ABSTRACT Background: Tools such as MELD score and DRI are currently used to predict risks and benefits on liver allocation for transplantation. Aim: To evaluate the relation between donor quality and ...recipient severity on liver allocation. Methods: Liver transplants performed in 2017 and 2018 were evaluated. Data were collected from Paraná’s State Government Registry. DRI was evaluated in relation to recipient MELD score and position on waiting list. Results: It was observed relation between DRI and position on waiting list: higher risk organs were allocated to recipients with worse waiting list position. There was no relation between DRI and MELD score. Afrodescendents and elderly donor organs were allocated to lower MELD score and worse waiting list position recipients. Conclusion: There is no relation between DRI and MELD on liver allocation. However, DRI interferes with allocation decision based on recipients waiting list position. Donor race and age interfere on both recipient MELD score and waiting list position
RESUMO Racional: Visando prever riscos e benefícios na alocação de órgãos no transplante hepático, são utilizados sistemas como o MELD, atual critério classificatório da lista de espera de transplantes, e o DRI, ferramenta que avalia fatores de risco do doador. Objetivo: Relacionar a qualidade do doador de fígado com a gravidade do seu receptor. Métodos: Foram avaliados os transplantes hepáticos realizados entre 2017 e 2018 no Estado do Paraná. Os dados foram coletados no sistema eletrônico da Central Estadual de Transplantes. Informações dos doadores foram relacionadas às dos receptores através da relação entre o DRI e o MELD e a posição do receptor na lista de espera. Resultados: Foram avaliados 520 doadores e 520 receptores. Observou-se relação entre DRI e posição na lista de espera: órgãos de doadores com maior risco pelo DRI foram alocados para receptores com pior posição na lista de espera. Não houve correlação entre o DRI e o MELD. No entanto, órgãos de doadores da raça negra ou com idade maior ou igual a 60 anos foram alocados para receptores com MELD mais baixo e com pior posição na lista de espera. Conclusão: Não existe relação entre o DRI e o MELD na distribuição de enxertos hepáticos no Estado do Paraná. O DRI interfere na alocação de acordo com a posição do receptor na lista de espera. A idade e a raça dos doadores interferem na alocação de acordo com o MELD e a posição em lista dos receptores.

Serum sodium was incorporated to MELD score for the allocation of liver transplantation In the USA in 2016. Hyponatremia significantly increased the efficacy of the score to predict mortality on the ...waiting list. Such modification was not adopted in Brazil.
To carry out a simulation using MELD-Na as waiting list ordering criteria in the state of Paraná and to compare to the list ordered according to MELD score.
The study used data of 122 patients waiting for hepatic transplantation and listed at Parana´s Transplantation Central. Two classificatory lists were set up, one with MELD, the current qualifying criteria, and another with MELD-Na. We analyzed the changes on classification comparing these two lists.
Among all patients, 95.1% of the participants changed position, 30.3% showed improvement, 64.8% presented worsening and 4.9% maintained their position. There were 19 patients with hyponatremia, of whom 94.7% presented a change of position, and in all of them there was an improvement of position. One hundred and one patients presented sodium within the normal range and 95% of them presented a change of position: Improved placement was observed in 18.8%, and worsened placement in 76.2%. Two patients presented hypernatremia and changed their position, both worsening the placement. There was a significant different behavior on waiting list according to sodium serum level when MELD-Na was applied.
The inclusion of serum sodium caused a great impact in the classification, bringing benefit to patients with hyponatremia.
