ABSTRACT Introduction: Blood transfusion is one of the most common medical practices worldwide. However, current scientific literature has shown that the immunomodulatory effects of blood transfusion are associated with an increased likelihood of infection, prolonged hospitalization, and morbimortality. Also, it means high costs for healthcare systems. Methods: In this context, acknowledging that blood transfusions are essentially heterologous cell transplantations, the use of therapeutic options has gained strength and is collectively known as the patient blood management (PBM) program. PBM is an approach based on three main pillars: (1) treating anemias and coagulopathies in an optimized manner, especially in the preoperative period; (2) optimizing perioperative hemostasis and the use of blood recovery systems to avoid the loss of the patient's blood; (3) anemia tolerance, with improved oxygen delivery and reduced oxygen demand, particularly in the postoperative period. Results: Current scientific evidence supports the effectiveness of PBM by reducing the need for blood transfusions, decreasing associated complications, and promoting more efficient and safer blood management. Thus, PBM not only improves clinical outcomes for patients but also contributes to the economic sustainability of healthcare systems. Conclusion: The aim of this review was to summarize PBM strategies in a comprehensive, evidence-based approach through a systematic and structured model for PBM implementation in tertiary hospitals. The recommendations proposed herein are from researchers and experts of a high-complexity university hospital in the network of the Sistema Único de Saúde, presenting itself as a strategy that can be followed as a guideline for PBM implementation in other settings.

Resumen Objetivo Evaluar los conocimientos de pacientes y profesionales de la salud sobre protocolos de vacunación tras un trasplante hepático, antes y después de aplicar una estrategia educativa de sensibilización en esta población. Métodos Los pacientes (n=124) fueron sometidos a la intervención educativa mediante el acceso a un sitio web con videos educativos, y los profesionales de la salud (n=11), mediante un simposio y el acceso a información en la página web del proyecto. Para analizar el efecto de la intervención, se realizaron análisis cualitativos de conocimiento con cuestionaros antes y después de la intervención. Resultados Entre los pacientes, el sexo masculino fue predominante (66,9 %) y la edad promedio fue 52,2 años (SD + 15,9). El 82,2 % de los pacientes fue a una Unidad Básica de Salud (UBS) para recibir la vacuna y el 13,7 % de ellos acudió a un Centro de Referencia para Inmunobiológicos Especiales (CRIE). Solo el 46,7 % recibió instrucciones sobre vacunación tras el trasplante hepático. De los 111 cuestionarios respondidos por profesionales de la salud, el 46,5 % no consultó el catálogo de vacunas, el 61,3 % derivó a los pacientes a una UBS y el 38,7 % a un CRIE. En el análisis posintervención, el 66,1 % de los pacientes miró los videos educativos sobre vacunación. De ellos, el 62,2 % mencionó haber mejorado su comprensión sobre vacunas y el 91,4 % se sintió más seguro para vacunarse. Después de la intervención educativa, 45 profesionales de la salud respondieron el cuestionario. El 30,4 % afirmó saber qué vacunas prescribir y el 67,4 % recomendó vacunas a familiares de los pacientes. Conclusión La estrategia educativa propuesta aplicada en este estudio demostró un aumento de conocimiento sobre los protocolos de inmunización tras un trasplante hepático. Esto pude ayudar a evitar el riesgo potencial de la falta de información y el no abordar el tema de la vacunación por parte de los profesionales de la salud. hepático población n=124 n124 n 124 (n=124 n=11, n11 n=11 , 11 (n=11) proyecto 66,9 669 66 9 (66, 522 52 2 52, SD 15,9. 159 15,9 . 15 15,9) 822 82 82, (UBS 137 13 7 13, CRIE (CRIE) 467 46 46, 465 5 613 61 3 61, 387 38 38, posintervención 661 1 66, 622 62 62, 914 91 4 91, vacunarse cuestionario 304 30 30, 674 67 67, n=12 n12 12 (n=12 n1 n=1 (n=11 6 (66 15, 8 (CRIE (n=1 n= (6 (n= ( (n

Resumo Objetivo Avaliar o conhecimento de pacientes e profissionais de saúde sobre os protocolos de vacinação no pós-transplante hepático antes e após a aplicação de uma estratégia educativa de conscientização nessa população. Métodos Os pacientes (n=124) foram submetidos à intervenção educativa através do acesso a uma página web com vídeos educativos e, para os profissionais de saúde (n=111), através de um simpósio e acesso à informação na página virtual do projeto. Para analisar o efeito da intervenção, análises qualitativas de conhecimento foram realizadas por meio de questionários antes e depois das intervenções. Resultados Entre os pacientes, predominou o sexo masculino (66,9%) e a média de idade foi de 55,2 anos (DP + 15,9). 82,2% dos pacientes procuraram uma UBS para serem vacinados e 13,7% deles, os CRIEs (Centro de Referência para Imunobiológicos Especiais). Apenas 46,7% receberam orientações sobre vacinas após o transplante hepático. Dos 111 questionários respondidos pelos profissionais de saúde, 46,5% não consultaram a carteira de vacinas, 61,3% encaminharam os pacientes para UBS e 38,7%, para um CRIE. Na análise pós-intervenção, 66,1% dos pacientes assistiram a vídeos educativos sobre vacinação. Destes, 62,2% disseram ter melhorado seu entendimento sobre as vacinas e 91,4% se sentem mais seguros para vacinar. Após a intervenção educativa, 45 profissionais de saúde responderam ao questionário. 30,4% afirmaram saber quais vacinas prescrever e 67,4% indicaram vacinas para familiares de pacientes. Conclusão A estratégia educacional proposta aplicada neste estudo mostrou aumentar a conscientização sobre os protocolos de imunização pós-transplante hepático. Isso pode contribuir para evitar o risco potencial de falta de informação e não abordagem da vacinação pelos profissionais de saúde. póstransplante pós população n=124 n124 n 124 (n=124 n=111, n111 n=111 , (n=111) projeto intervenções 66,9% 669 66 9 (66,9% 552 55 2 55, DP 15,9. 159 15,9 . 15 15,9) 822 82 82,2 137 13 7 13,7 deles Centro Especiais.

Abstract Objective To evaluate patients’ and healthcare professionals’ knowledge about vaccination protocols in post-liver transplantation before and after applying an educational awareness strategy in this population. Methods Patients (n=124) underwent the educational intervention through access to a webpage containing educational videos and, for health professionals (n=111), through a symposium and access to information on the project’s virtual page. To analyze the effect of the intervention, qualitative analyses of knowledge were carried out using questionnaires before and after the interventions. Results Among patients, males were predominant (66.9%) and the mean age was 55.2 years old (SD + 15.9). 82.2% of patients visited a UBS to be vaccinated and 13.7% of them the CRIEs (Reference Center for Special Immunobiologicals). Only 46.7% received orientation about vaccines after liver transplantation. From the 111 questionnaires answered by health professionals, 46.5% did not check the vaccine portfolio, 61.3% referred patients to UBS and 38.7% to a CRIE. In the post-intervention analysis, 66.1% of patients watched educational videos about vaccination. Of these, 62.2% said they had improved their understanding about vaccines and 91.4% feel safer to vaccinate. After the educational intervention, 45 health professionals answered the questionnaire. 30.4% said they knew which vaccines to prescribe, and 67.4% recommended vaccines to patients’ relatives. Conclusion The proposed educational strategy applied in this study shown to increase awareness regarding the post-liver transplant immunization protocols. This may contribute to avoiding the potential risk of lack of information and failure to address vaccination by healthcare professionals. postliver post population n=124 n124 n 124 (n=124 n=111, n111 n=111 , (n=111) projects project s page interventions 66.9% 669 66 9 (66.9% 552 55 2 55.

ABSTRACT BACKGROUND: Although autonomic dysfunction has been shown to be associated with liver cirrhosis, the prevalence and prognostic implications are unclear. Abnormal heart rate variability (HRV), a measure of autonomic function, has not been well investigated in cirrhosis. OBJECTIVE: To evaluate the prevalence of high-risk HRV parameters in a cohort of cirrhotic patients and their association with cardiac dysfunction and mortality. DESIGN AND SETTING: Prospective observational study conducted in the Federal University of São Paulo. METHOD: A cohort of 120 patients, comprising 17 healthy controls and 103 cirrhotic outpatients, was evaluated and followed for 10 months. HRV analysis was based on 24-hour Holter monitoring and defined using time-domain and frequency-domain parameters. RESULTS: The HRV parameters were statistically lower in cirrhotic patients than in healthy subjects. High-risk HRV parameters were prevalent, such that 64% had at least one high-risk parameter. Time-domain parameters correlated with Child scores (P < 0.0001). In regression models, HRV parameters were independent predictors of diastolic dysfunction and mortality. During 10 months of follow-up, there were 11 deaths, all of patients with at least one high-risk HRV parameter. Kaplan-Meier analysis estimated low survival rates among patients with standard deviation of normal-to-normal RR intervals (SDNN) < 100. CONCLUSION: Reduced HRV is prevalent in liver cirrhosis and is related to cardiac dysfunction, severity of liver disease and mortality. Abnormal high-risk HRV parameters are prevalent among cirrhotic patients and are also predictors of mortality. Our findings highlight the need for a more careful cardiac evaluation of cirrhotic patients.

ABSTRACT Purpose: Simultaneous pancreas-kidney transplantation (SPKT) brings several benefits for insulin-dependent type-1 diabetic patients associated with end-stage renal disease (ESRD). However, data on psychological outcomes for the waiting list and the transplanted patients are still lacking. Methods: Using the psychological Beck inventories of anxiety (BAI) and depression (BDI), 39 patients on the waiting list were compared to 88 post-transplanted patients who had undergone SPKT. Results: Significant differences were found regarding depression (p = 0.003) but not anxiety (p = 0.161), being the pretransplant patients more vulnerable to psychological disorders. Remarkable differences were observed relative to the feeling of punishment (p < 0.001) and suicidal thoughts (p = 0.008) between the groups. It was observed that patients who waited a longer period for the transplant showed more post-transplant anxiety symptoms due to the long treatment burden (p = 0.002). Conclusions: These results demonstrated the positive impact of SPKT on psychological aspects related to depression when comparing the groups. The high number of stressors in the pretransplant stage impacts more severely the psychosocial condition of the patient.

RESUMO Objetivo: avaliar o impacto financeiro das complicações pós-operatórias no transplante simultâneo pâncreas-rim durante a internação hospitalar. Métodos: estudo retrospectivo dos dados da internação hospitalar dos pacientes submetidos consecutivamente ao transplante simultâneo pâncreas-rim no período de janeiro de 2008 a dezembro de 2014 no Hospital do Rim/Fundação Oswaldo Ramos. As principais variáveis estudadas foram a reoperação, pancreatectomia do enxerto, óbito, complicações pós-operatórias (cirúrgicas, infecciosas, clínicas e imunológicas) e os dados financeiros da internação para o transplante. Resultados: a amostra foi composta de 179 pacientes transplantados. As características dos doadores e receptores foram semelhantes nos pacientes com e sem complicações. Na análise dos dados, 58,7% dos pacientes apresentaram alguma complicação pós-operatória, 21,8% necessitaram de reoperação, 12,3%, de pancreatectomia do enxerto e 8,4% evoluíram para o óbito. A necessidade de reoperação ou pancreatectomia do enxerto aumentou o custo da internação em 53,3% e 78,57%, respectivamente. A presença de complicação pós-operatória aumentou significativamente o custo. Entretanto, a presença de óbito, hérnia interna, infarto agudo do miocárdio, acidente vascular cerebral e disfunção do enxerto pancreático não apresentaram significância estatística no custo, cuja média foi de US$ 18,516.02. Conclusão: complicações pós-operatórias, reoperação e pancreatectomia do enxerto aumentaram significativamente o custo médio da internação hospitalar do SPK, assim como as complicações cirúrgicas, infecciosas, clínicas e imunológicas. No entanto, o óbito durante a internação, a hérnia interna, o infarto agudo do miocárdio, o acidente vascular cerebral e a disfunção do enxerto pancreático não interferiram estatisticamente neste custo.

ABSTRACT Objective: considering simultaneous pancreas-kidney transplantation cases, to evaluate the financial impact of postoperative complications on hospitalization cost. Methods: a retrospective study of hospitalization data from patients consecutively submitted to simultaneous pancreas-kidney transplantation (SPKT), from January 2008 to December 2014, at Kidney Hospital/Oswaldo Ramos Foundation (Sao Paulo, Brazil). The main studied variables were reoperation, graft pancreatectomy, death, postoperative complications (surgical, infectious, clinical, and immunological ones), and hospitalization financial data for transplantation. Results: the sample was composed of 179 transplanted patients. The characteristics of donors and recipients were similar in patients with and without complications. In data analysis, 58.7% of the patients presented some postoperative complication, 21.8% required reoperation, 12.3% demanded graft pancreatectomy, and 8.4% died. The need for reoperation or graft pancreatectomy increased hospitalization cost by 53.3% and 78.57%, respectively. The presence of postoperative complications significantly increased hospitalization cost. However, the presence of death, internal hernia, acute myocardial infarction, stroke, and pancreatic graft dysfunction did not present statistical significance in hospitalization cost (in average US$ 18,516.02). Conclusion: considering patients who underwent SPKT, postoperative complications, reoperation, and graft pancreatectomy, as well as surgical, infectious, clinical, and immunological complications, significantly increased the mean cost of hospitalization. However, death, internal hernia, acute myocardial infarction, stroke, and pancreatic graft dysfunction did not statistically interfere in hospitalization cost.

RESUMO Objetivo: avaliar as condições bucais e os principais fatores predisponentes para tratamento odontológico de pacientes em lista de espera para transplante simultâneo de pâncreas-rim e para transplante hepático, em um centro único. Métodos: foram avaliados 100 pacientes na fila de espera, 50 candidatos a transplante hepático e 50 a transplante simultâneo de pâncreas-rim, no período de agosto de 2015 a fevereiro de 2018. Exames extra e intrabucais foram correlacionados com variáveis demográficas pré-transplante. Resultados: a principal alteração bucal nos candidatos a transplante de pâncreas-rim e de transplante hepático foram dentes cariados, perdidos e obturados, presentes em 83% e 100% dos candidatos, respectivamente (P=0,03). A necessidade de tratamento odontológico foi igual nos dois grupos: 71% e 70%. Nos candidatos a transplante hepático, os fatores predisponentes para tratamento odontológico foram idade, cor e diagnóstico etiológico da cirrose hepática. Não identificamos fatores predisponentes para tratamento odontológico nos candidatos a transplante simultâneo pâncreas-rim. Conclusão: pacientes candidatos a transplante simultâneo de pâncreas-rim e transplante hepático apresentaram higiene bucal precária com presença de cárie, raízes residuais, gengivite e periodontite, revelando que a avaliação odontológica deve fazer parte do protocolo de atendimento dos pacientes em fila de espera para transplantes.

ABSTRACT Objective: to evaluate the oral conditions and the main predisposing factors for dental treatment of patients on the waiting list for liver and simultaneous pancreas-kidney transplantation, in a single center. Methods: we evaluated 100 patients in the waiting list, 50 candidates for liver transplantation and 50 for simultaneous kidney-pancreas transplantation, from August 2015 to February 2018. We correlated extra and intraoral examinations with pre-transplant demographic variables. Results: the main oral alteration in the pancreas-kidney and liver transplant candidates were decayed, lost and filled teeth, present in 83% and 100% of the candidates, respectively (p=0.03). The need for dental treatment was equal in both groups: 71% and 70%. In liver transplant candidates, the predisposing factors for dental treatment were age, color and etiological diagnosis of liver cirrhosis. We did not identify predisposing factors for dental treatment in candidates for simultaneous pancreas-kidney transplant. Conclusion: candidates for liver and for simultaneous pancreas-kidney transplantation had poor oral hygiene, with cavities, residual roots, gingivitis and periodontitis, revealing that dental evaluation should be part of the transplantation waiting list.

Resumo Objetivo: Demonstrar o valor da abordagem transparieto-hepática no tratamento de estenoses biliares em pacientes pediátricos submetidos a transplante de fígado. Materiais e Métodos: Estudo retrospectivo com revisão de prontuários, exames laboratoriais e de imagem dos pacientes pediátricos submetidos a transplante hepático. Foram incluídos pacientes com suspeita de estenose de vias biliares que realizaram colangiografia transparieto-hepática para diagnóstico, entre 1º de setembro de 2012 e 31 maio de 2015. Os dados de 12 pacientes foram coletados, dos quais 7 apresentaram estenose de vias biliares. Resultados: No total foram realizados 21 procedimentos: 2 pacientes realizaram dois procedimentos (28,6%), 3 pacientes realizaram três procedimentos (42,8%) e 2 pacientes realizaram quatro procedimentos (28,6%). A média de procedimentos por paciente foi 3 (variação: 2–4) e o intervalo médio entre os procedimentos foi 2,9 meses (variação: 0,8–9,1 meses). A permanência média do dreno foi 5,8 meses (variação: 3,1–12,6 meses). Uma paciente apresentou hemobilia com instabilidade hemodinâmica, tratada com sucesso por via endovascular. O sucesso clínico foi alcançado nos 7 pacientes e o seguimento médio após retirada do dreno foi 15,4 meses (variação: 5,3–26,7 meses). Conclusão: A abordagem transparieto-hepática das estenoses biliares em crianças submetidas a transplante de fígado demonstrou ser tratamento eficaz, com baixo índice de complicações.

Abstract Objective: To evaluate the percutaneous transhepatic approach to the treatment of biliary strictures in pediatric patients undergoing liver transplantation. Materials and Methods: This was a retrospective study of data obtained from the medical records, laboratory reports, and imaging examination reports of pediatric liver transplant recipients who underwent percutaneous transhepatic cholangiography, because of clinical suspicion of biliary strictures, between 1st September 2012 and 31 May 2015. Data were collected for 12 patients, 7 of whom were found to have biliary strictures. Results: In the 7 patients with biliary strictures, a total of 21 procedures were carried out: 2 patients (28.6%) underwent the procedure twice; 3 (42.8%) underwent the procedure three times; and 2 (28.6%) underwent the procedure four times. Therefore, the mean number of procedures per patient was 3 (range, 2–4), and the average interval between them was 2.9 months (range, 0.8–9.1 months). The drainage tube remained in place for a mean of 5.8 months (range, 3.1–12.6 months). One patient presented with a major complication, hemobilia, which was treated with endovascular embolization. Clinical success was achieved in all 7 patients, and the mean follow-up after drain removal was 15.4 months (range, 5.3–26.7 months). Conclusion: The percutaneous transhepatic approach to treating biliary strictures in pediatric liver transplant recipients proved safe, with high rates of technical and clinical success, as well as a low rate of complications.

RESUMO Objetivo: comparar o resultado do transplante de fígado por hepatocarcinoma em pacientes submetidos ou não ao tratamento loco-regional e downstaging, em relação à sobrevida e risco de recidiva na fila de transplante. Métodos: estudo retrospectivo dos pacientes portadores de hepatocarcinoma submetidos a transplante hepático na região metropolitana de São Paulo, entre janeiro de 2007 e dezembro de 2011, a partir de doador falecido. A amostra foi constituída de 414 pacientes. Destes, 29 foram incluídos na lista por downstaging. Os demais 385 foram submetidos ou não ao tratamento loco-regional. Resultados: as análises dos 414 prontuários demonstraram um predomínio de pacientes do sexo masculino (79,5%) e com média de idade de 56 anos. O tratamento dos nódulos foi realizado em 56,4% dos pacientes em fila de espera para o transplante. O método mais utilizado foi a quimio-embolização (79%). Os pacientes submetidos ao tratamento loco-regional tiveram redução significativa no tamanho do maior nódulo (p<0,001). Não houve diferença estatística entre grupos com e sem tratamento loco-regional (p=0,744) e em relação à mortalidade entre pacientes incluídos no Critério de Milão ou ao downstaging (p=0,494). Conclusões: não houve diferença na sobrevida e ocorrência de recidiva associadas ao tratamento loco-regional. Os pacientes incluídos através do processo de downstaging apresentaram resultados de sobrevida comparáveis àqueles previamente classificados como Critério de Milão/Brasil.

ABSTRACT Objective: to compare the outcome of liver transplantation for hepatocarcinoma in submitted or not to locoregional treatment and downstaging regarding survival and risk of recurrence in transplant waiting list patients. Methods: retrospective study of patients with hepatocarcinoma undergoing liver transplantation in the metropolitan region of São Paulo, between January 2007 and December 2011, from a deceased donor. The sample consisted of 414 patients. Of these, 29 patients were included in the list by downstaging. The other 385 were submitted or not to locoregional treatment. Results: the analysis of 414 medical records showed a predominance of male patients (79.5%) with average age of 56 years. Treatment of the lesions was performed in 56.4% of patients on the waiting list for transplant. The most commonly used method was chemoembolization (79%). The locoregional patients undergoing treatment had a significant reduction in nodule size greater (p<0.001). There was no statistical difference between groups with and without locoregional treatment (p=0.744) and on mortality among patients enrolled in the Milan criteria or downstaging (p=0.494). Conclusion: there was no difference in survival and recurrence rate associated with locoregional treatment. Patients included by downstaging process had comparable survival results to those previously classified as Milan/Brazil criteria.

Abstract Purpose: To analyze the use of this sponge in pediatric patients undergoing split-liver transplantation. Methods: Retrospective study, including 35 pediatric patients undergoing split-liver transplantation, divided into two groups according to the use of the sponge: 18 patients in Group A (no sponge) and 17 in Group B (with sponge). Results: The characteristics of recipients and donors were similar. We observed greater number of reoperation due to bleeding in the wound area in Group A (10 patients - 55.5%) than in Group B (3 patients - 17.6%); p = 0.035. The median volume of red blood cells transfused in Group A was significantly higher (73.4 ± 102.38 mL/kg) than that in Group B (35.1 ± 41.67 mL/kg); p = 0.048. Regarding bile leak there was no statistical difference. Conclusion: The use of the human fibrinogen and thrombin sponge, required lower volume of red blood cell transfusion and presented lower reoperation rates due to bleeding in the wound area.

ABSTRACT Background. Hepatocellular carcinoma (HCC) is the most common malignancy that develops in cirrhotic livers. Its clinical and epidemiological characteristics and mortality rates vary according to geographical region. The objective of this study was to evaluate the clinical profile, epidemiological characteristics, laboratory parameters, treatment and survival of patients with HCC. Material and methods. Patients with HCC seen between 2000 and 2012 were studied. The Kaplan-Meier method was used for survival analysis according to variables in question. Results. The study included 247 patients with a mean age of 60 ± 10 years. There was a predominance of males (74%). The main etiologies of HCC were HCV infection (55%), excessive alcohol consumption (12%), and HBV infection (8%). Liver cirrhosis was present in 92% of cases. The mean tumor number and diameter were 2 and 5 cm, respectively. Patients meeting the Milan criteria corresponded to 43% of the sample. Liver transplantation was performed in 22.4% of patients of the Milan subset and in 10% of the whole sample. The overall mean survival was 60 months, with a 1-, 3- and 5-year survival probability of 74%, 40% and 29%, respectively. Lower survival was observed among patients with alcoholic etiology. Survival was higher among patients submitted to liver transplantation (P < 0.001), TACE (P < 0.001), or any kind of treatment (P < 0.001). However, no difference was found for surgical resection (P = 0.1) or sorafenib (P = 0.1). Conclusion. Patients with HCC were mainly older men diagnosed at an advanced stage. Treatment was associated with better overall survival, but few patients survived to be treated.

RESUMO Racional: Estratégia cirúrgica para aumentar o número de transplantes hepáticos na população pediátrica é a transecção hepática ex-situ (redução ou split). No entanto, ela está associada com complicações, tais como hemorragia e fístulas. A esponja de fibrinogênio e trombina humana é útil para melhorar a hemostasia nas operações hepáticas. Objetivo: Comparar transplantes hepáticos pediátricos com transecção hepática ex-situ (redução ou split) com ou sem a esponja de fibrinogênio e trombina humana. Métodos: Foi realizada análise prospectiva de 21 pacientes submetidos ao transplante de fígado com transecção hepática ex-situ com a aplicação da esponja de fibrinogênio e trombina humana na área cruenta (grupo A) e análise retrospectiva de 59 pacientes sem a esponja (grupo B). Resultados: As características dos receptores e doadores eram semelhantes. Observou-se menor número de reoperações devido à hemorragia na área da cruenta no grupo A (14,2%) em comparação com o grupo B (41,7%, p=0,029). Não houve diferença em relação à fístula biliar (grupo A: 17,6%, grupo B: 5,1%, p=0,14). Conclusão: Houve menor número de reoperações por sangramento da área cruenta do enxerto hepático quando a esponja de fibrinogênio e trombina humana foi utilizada.

ABSTRACT Background: Surgical strategy to increase the number of liver transplants in the pediatric population is the ex-situ liver transection (reduction or split). However, it is associated with complications such as hemorrhage and leaks. The human fibrinogen and thrombin sponge is useful for improving hemostasis in liver surgery. Aim: Compare pediatric liver transplants with ex-situ liver transection (reduction or split) with or without the human fibrinogen and thrombin sponge. Methods: Was performed a prospective analysis of 21 patients submitted to liver transplantation with ex-situ liver transection with the application of the human fibrinogen and thrombin sponge in the wound area (group A) and retrospective analysis of 59 patients without the sponge (group B). Results: The characteristics of recipients and donors were similar. There were fewer reoperations due to bleeding in the wound area in group A (14.2%) compared to group B (41.7%, p=0.029). There was no difference in relation to the biliary leak (group A: 17.6%, group B: 5.1%, p=0.14). Conclusion: There was a lower number of reoperations due to bleeding of the wound area of the hepatic graft when the human fibrinogen and thrombin sponge were used.

ABSTRACT PURPOSE: To describe an animal model for acute liver failure by intraperitoneal d-galactosamine injections in rats and to define when is the best time to intervene through King's College and Clichy´s criteria evaluation. METHODS: Sixty-one Wistar female rats were distributed into three groups: group 1 (11 rats received 1.4 g/kg of d-galactosamine intraperitoneally and were observed until they died); group 2 (44 rats received a dose of 1.4 g/kg of d-galactosamine and blood and histological samples were collected for analysis at 12 , 24, 48 , 72 and 120 hours after the injection); and the control group as well (6 rats) . RESULTS: Twelve hours after applying d-galactosamine, AST/ALT, bilirubin, factor V, PT and INR were already altered. The peak was reached at 48 hours. INR > 6.5 was found 12 hours after the injection and factor V < 30% after 24 hours. All the laboratory variables presented statistical differences, except urea (p = 0.758). There were statistical differences among all the histological variables analyzed. CONCLUSION: King's College and Clichy´s criteria were fulfilled 12 hours after the d-galactosamine injection and this time may represent the best time to intervene in this acute liver failure animal model.

RESUMO Racional: A neoplasia sólida pseudopapilar é tumor raro de pâncreas de tratamento cirúrgico. No entanto, sua causa ainda gera discussões. Objetivo: Analisar os dados clínicos, do diagnóstico e do tratamento da dessa neoplasia. Métodos: Estudo retrospectivo com dados médicos de pacientes tratados entre janeiro de 1997 a julho de 2015. Resultados: Foram identificados 17 casos. A maioria era de mulheres (94,11%) e a média de idade foi de 32,88 anos. A principal queixa era massa abdominal (47,05%). A localização mais frequente era no corpo/cauda do pâncreas (72,22%) e a operação mais realizada foi a pancreatectomia corpocaudal com esplenectomia (64,70%). Nenhum caso apresentou metástase no momento do diagnóstico. Operação conservadora de parênquima pancreático foi realizada em apenas três casos. A taxa de complicações no pós-operatório foi de 35,29% e a principal complicação foi fístula pancreática (29,41%). Nenhum paciente realizou adjuvância no seguimento. Conclusões: A mais comum apresentação clínica da neoplasia sólida pseudopapilar é de massa abdominal. Ela é de tratamento cirúrgico e pancreatectomia corpocaudal com esplenectomia é o procedimento mais realizado para seu tratamento.

ABSTRACT Background: The solid pseudopapillary neoplasm is a rare tumor of the pancreas. However, it´s etiology still maintain discussions. Aim: To analyze it´s clinical data, diagnosis and treatment. Methods: A retrospective study of medical records of all patients treated from January 1997 until July 2015. Results: Were identified 17 cases. Most patients were women (94.11%) and the average age was 32.88 years. The main complaint was abdominal mass (47.05%). The most frequent location was in the body/tail of the pancreas (72.22%) and the most frequently performed surgery was distal pancreatectomy with splenectomy (64.70%). No patient had metastases at diagnosis. Conservative surgery for pancreatic parenchyma was performed in only three cases. The rate of complications in the postoperative period was 35.29% and the main complication was pancreatic fistula (29.41%). No patient underwent adjuvant treatment. Conclusions: The treatment is surgical and the most common clinical presentation is abdominal mass. Distal pancreatectomy with splenectomy was the most frequently performed surgery for its treatment.

ResumoObjetivo:Este estudo teve como objetivo relatar a experiência dos autores de embolização arterial transcateter com o uso de uma mistura de lipiodol e etanol em três casos de hemangiomas hepáticos gigantes sintomáticos e não ressecáveis.Materiais e Métodos:Três hemangiomas hepáticos gigantes sintomáticos e não ressecáveis em três pacientes foram embolizados com o uso de uma mistura transarterial de etanol e lipiodol.Resultados:A regressão dos sintomas e a melhora na qualidade de vida foram observadas em todos os casos. Nenhuma complicação foi encontrada e todos os pacientes receberam alta em até 12 horas após o procedimento.Conclusão:O etanol misturado com o lipiodol foi um tratamento eficaz e seguro para hemangiomas hepáticos gigantes sintomáticos nesta pequena série de pacientes.

AbstractObjective:The present article is aimed at reporting the author’s experience with transcatheter arterial embolization using a lipiodol-ethanol mixture in three cases of unresectable symptomatic giant hepatic hemangiomas.Materials and Methods:The cases of three patients with giant unresectable symptomatic hepatic hemangiomas embolized in the period 2009–2010 were retrospectively reviewed. In all the cases, transarterial embolization was performed with an ethanol-lipiodol mixture.Results:Symptoms regression and quality of life improvement were observed in all the cases. No complications were observed and all the patients were discharged within 12 hours after the procedure.Conclusion:Transcatheter arterial embolization using ethanol mixed with lipiodol was a safe and effective treatment for symptomatic giant hepatic hemangiomas in this small series of patients.

PURPOSE:To perform a cost analysis of simultaneous pancreas-kidney transplantation (SPKT) in a Brazilian hospital.METHODS: Between January 2008 and December 2011, 105 consecutive SPKTs at the Hospital of Kidney and Hypertension in Sao Paulo were evaluated. We evaluated the patient demographics, payment source (public health system or supplementary system), and the impact of each hospital cost component. The evaluated costs were corrected to December 2011 values and converted to US dollars.RESULTS: Of the 105 SPKT patients, 61.9% were men, and 38.1% were women. Eight patients died, and 97 were discharged (92.4%). Eighty-nine procedures were funded by the public health system. The cost for the patients who were discharged was $18.352.27; the cost for the deceased patients was $18.449.96 (p = 0.79). The FOR for SPKT during this period was positive at $5,620.65. The costs were distributed as follows: supplies, 36%; administrative costs, 20%; physician fees, 15%; intensive care unit, 10%; surgical center, 10%; ward, 9%.CONCLUSION: Mortality did not affect costs, and supplies were the largest cost component.
