ABSTRACT BACKGROUND: Hepatosplenic schistosomiasis is an endemic disease prevalent in tropical countries and is associated with a high incidence of portal vein thrombosis. Inflammatory changes caused by both parasitic infection and portal thrombosis can lead to the development of chronic liver disease with potential carcinogenesis. AIMS: To assess the incidence of portal vein thrombosis and hepatocellular carcinoma in patients with schistosomiasis during long-term follow-up. METHODS: A retrospective study was conducted involving patients with schistosomiasis followed up at our institution between 1990 and 2021. RESULTS: A total of 126 patients with schistosomiasis were evaluated in the study. The mean follow-up time was 16 years (range 5–31). Of the total, 73 (57.9%) patients presented portal vein thrombosis during follow-up. Six (8.1%) of them were diagnosed with hepatocellular carcinoma, all with portal vein thrombosis diagnosed more than ten years before. CONCLUSIONS: The incidence of hepatocellular carcinoma in patients with schistosomiasis and chronic portal vein thrombosis highlights the importance of a systematic long-term follow-up in this group of patients.

RESUMO RACIONAL: A esquistossomose hepatoesplênica é uma doença endêmica prevalente em países tropicais e está associada a uma alta incidência de trombose da veia porta. Alterações inflamatórias causadas tanto pela infecção parasitária quanto pela trombose portal podem levar ao desenvolvimento de doença hepática crônica com potencial carcinogênico. OBJETIVOS: Avaliar a incidência de trombose da veia porta e carcinoma hepatocelular em pacientes com esquistossomose durante um seguimento de longo prazo. MÉTODOS: Foi realizado estudo retrospectivo envolvendo pacientes com esquistossomose acompanhados em nossa instituição entre 1990 e 2021. RESULTADOS: Um total de 126 pacientes com esquistossomose foram avaliados no estudo. O tempo médio de acompanhamento foi de 16 anos (variando de 5 a 31). Do total, 73 (57,9%) pacientes apresentaram trombose da veia porta durante o seguimento e seis (8,1%) deles foram diagnosticados com carcinoma hepatocelular, todos com trombose da veia porta diagnosticada há mais de 10 anos. CONCLUSÕES: A incidência de carcinoma hepatocelular em pacientes com esquistossomose e trombose da veia porta crônica destaca a importância de um acompanhamento sistemático de longo prazo nesse grupo de pacientes.

Abstract Objectives: To evaluate results of patients undergoing liver resection in a single center over the past two decades with a particular look at Colorectal Liver Metastasis (CRLM) and Hepatocellular Carcinoma (HCC). Method: Patients were divided into two eras, from 2000 to 2010 (Era 1) and 2011 to 2020 (Era 2). The most frequent diagnosis was CRLM and HCC, with 738 (52.4%) and 227 (16.1%) cases respectively. An evaluation of all liver resection cases and a subgroup analysis of both CRLM and HCC were performed. Preoperative and per operative variables and long-term outcomes were evaluated. Results: 1409 liver resections were performed. In Era 2 the authors observed higher BMI, more: minimally invasive surgeries, Pringle maneuvers, and minor liver resections; and less transfusion, less ICU necessity, and shorter length of hospital stay. Severe complications were observed in 14.7% of patients, and 90-day mortality was 4.2%. Morbidity and mortality between eras were not different. From 738 CRLM resections, in Era 2 there were significantly more patients submitted to neoadjuvant chemotherapy, bilateral metastases, and smaller sizes with significantly less transfusion, the necessity of ICU, and shorter length of hospital stay. More pedicle clamping, minimally invasive surgeries, and minor resections were also observed. From 227 HCC resections, in Era 2 significantly more minimally invasive surgeries, fewer transfusions, less necessity of ICU, and shorter length of hospital stay were observed. OS was not different between eras for CRLM and HCC. Conclusions: Surgical resection in a multidisciplinary environment remains the cornerstone for the curative treatment of primary and metastatic liver tumors.

Abstract The impact of Multivisceral Liver Resection (MLR) on the outcome of patients with Colorectal Liver Metastasis (CRLM) is unclear. The present systematic review aimed to compare patients with CRLM who underwent MLR versus standard hepatectomy regarding short- and long-term outcomes. MLR is a feasible procedure but has a higher risk of major complications. MLR did not negatively affect long-term survival, suggesting that an extended resection is an option for potentially curative treatment for selected patients with CRLM.

RESUMO - RACIONAL: O câncer colorretal é a terceira neoplasia mais frequente e metade dos pacientes desenvolvem metástase hepática. O melhor fator prognóstico na metástase hepática de câncer colorretal (MHCCR) é a possibilidade de ressecção com margens livres, porém a maioria permanece irressecável. O racional em realizar transplante hepático (TH) em pacientes portadores de MHCCR está na ampliação do número de pacientes ressecáveis através de uma hepatectomia total. OBJETIVO: Apresentar protocolo brasileiro para realização de transplante hepático em pacientes com MHCCR irressecável. MÉTODO: O protocolo foi realizado por duas instituições com grande volume de ressecções e transplantes hepáticos no Brasil, baseado no trabalho realizado pela Universidade de Oslo. A elaboração foi dividida em 4 etapas. RESULTADO: É apresentada proposta de protocolo para esta doença a ser validada na aplicação clínica. CONCLUSÃO: Foi possível elaborar protocolo de transplante hepático para MHCCR irressecável a fim de uniformizar o tratamento e melhor avaliar os resultados cirúrgicos.

ABSTRACT - BACKGROUND: Colorectal cancer (CRC) is the third most common neoplasm, and half of the patients with CRC develop liver metastasis. The best prognostic factor for colorectal liver metastasis (CRLM) is the possibility of performing a resection with free margins; however, most of them remain unresectable. The justification for performing liver transplantation (LT) in patients with CRLM regards an increase in the number of resectable patients by performing total hepatectomy. AIM: The aim of this study was to provide a Brazilian protocol for LT in patients with unresectable CRLM. METHOD: The protocol was carried out by two Brazilian institutions, which perform a large volume of resections and LTs, based on the study carried out at the University of Oslo. The elaboration of the protocol was conducted in four stages. RESULT: A protocol proposal for this disease is presented, which needs to be validated for clinical use. CONCLUSION: The development of an LT protocol for unresectable CRLM aims to standardize the treatment and to enable a better evaluation of surgical results.

RESUMO - RACIONAL: As principais indicações das hepatectomias video-laparoscópicas (HVL), inicialmente, eram nas lesões hepáticas benignas. À medida que a HVL se tornou mais popular, as indicações de doenças malignas superaram as de doenças benignas. Este estudo teve como objetivo discutir as indicações e resultados da HVL para o tratamento de tumores hepáticos benignos. MÉTODOS: De 445 HVL realizadas em um único centro, 100 (22,4%) foram para tumores benignos. Os autores discutem as indicações para ressecção e apresentam seus resultados perioperatórios. RESULTADOS: No total, 100 pacientes com tumores benignos foram avaliados, a saber: 66 casos de adenomas hepatocelulares; 14 de neoplasia mucinosa biliar; 13 de hiperplasia nodular focal; 4 de angiomiolipomas; e 3 de hemangiomas. O tamanho médio das lesões foi de 7,6 cm (3,1 a 19,6 cm). A taxa de morbidade total foi de 19%, sendo 9% classificados como Clavien-Dindo 3 ou 4 e não foi observada mortalidade. CONCLUSÃO: A HVL para tumores hepáticos benignos é segura e apresenta excelentes resultados. No entanto, as indicações para cirurgia são cada vez mais restritas, não sendo recomendável indicar a ressecção somente por se tratar de procedimento minimamente invasivo.

ABSTRACT - BACKGROUND: The main indications of the use of laparoscopic liver surgery (LLS), in the early days, were benign liver lesions. As LLS became more popular, indications for malignant diseases outnumbered those for benign ones. This study aims to rule out the indications and results of LLS for the treatment of benign liver tumors. METHODS: Out of 445 LLS performed in a single center, 100 (22.4%) were for benign tumors. The authors discuss the indications for resection and present their perioperative results. RESULTS: In total, 100 patients with benign tumors were evaluated. Specifically, these were as follows: 66 cases of hepatocellular adenomas; 14 cases of biliary mucinous neoplasm; 13 cases of focal nodular hyperplasia; 4 cases of angiomyolipomas; and 3 cases of hemangiomas with a mean size of 7.6 cm (ranging from 3.1 to 19.6 cm). The total morbidity rate was 19%, with 9% classified as Clavien-Dindo grades 3 or 4. No mortality was observed. CONCLUSION: LLS for benign liver tumors is safe and presents excellent results. However, indications for resection are increasingly restricted and should not be performed just because it is a minimally invasive procedure.

RESUMO Racional: O colangiocarcinoma hilar representa mais da metade de todos os casos de colangiocarcinoma; tem prognóstico reservado e sobrevida global mediana de 12- 24 meses após o diagnóstico. A proposta de realizar transplante hepático surgiu para ampliar a possibilidade de margens livres através de hepatectomia total nos portadores de tumoresirressecáveis com melhor prognóstico. Objetivo: Apresentar protocolo brasileiro para realização de transplante hepático em pacientes com colangiocarcinoma hilar. Método: O protocolo foi realizado por duas instituições com grande volume de ressecções e transplantes hepáticos no Brasil, baseado no trabalho realizado pela MayoClinic. A elaboração foi dividida em quatro etapas. Resultado: É apresentada proposta de protocolo para esta doença a ser validada na aplicação clínica. Conclusão: Foi possível elaborar protocolo de transplante hepático para colangiocarcinoma a fim de uniformizar o tratamento e melhor avaliar os resultados cirúrgicos.

ABSTRACT Background: Hilar cholangiocarcinoma represents more than half of all cholangiocarcinoma cases, having poor prognosis and presenting a median overall survival after diagnosis of 12-24 months. In patients who have unresectable tumors with a better prognosis, the proposal to perform liver transplantation emerged for expanding the possibility of free margins by performing total hepatectomy. Aim: To provide a Brazilian protocol for liver transplantation in patients with hilar cholangiocarcinoma. Method: The protocol was carried out by two Brazilian institutions which perform a large volume of resections and liver transplantations, based on the study carried out at the Mayo Clinic. The elaboration of the protocol was conducted in four stages. Result: A protocol proposal for this disease is presented, which needs to be validated for clinical use. Conclusion: The development of a liver transplantation protocol for cholangiocarcinoma aims not only to standardize the treatment, but also enable a better assessment of the surgical results in the future.

Abstract: En | Text: En | PDF: En

A combination of immunosuppressants may improve outcomes due to the synergistic effect of their different action mechanisms. Currently, there is no consensus regarding the best immunosuppressive protocol after liver transplantation. This review aimed to evaluate the effectiveness and safety of tacrolimus associated with mycophenolate mofetil (MMF) in patients undergoing liver transplantation. We performed a systematic review and meta-analysis of randomized clinical trials. Eight randomized trials were included. The proportion of patients with at least one adverse event related to the immunosuppression scheme with tacrolimus associated with MMF was 39.9%. The tacrolimus with MMF immunosuppression regimen was superior in preventing acute cellular rejection compared with that of tacrolimus alone (risk difference [RD]=-0.11; p =0.001). The tacrolimus plus MMF regimen showed no difference in the risk of adverse events compared to that of tacrolimus alone (RD=0.7; p=0.66) and cyclosporine plus MMF (RD=-0.7; p=0.37). Patients undergoing liver transplantation who received tacrolimus plus MMF had similar adverse events when compared to patients receiving other evaluated immunosuppressive regimens and had a lower risk of acute rejection than those receiving in the monodrug tacrolimus regimen.

RESUMO Racional: O tratamento de escolha para pacientes com hipertensão portal esquistossomótica com sangramento de varizes é a desconexão ázigo-portal mais esplenectomia (DAPE) associada à terapia endoscópica. Porém, estudos mostram aumento do calibre das varizes em alguns pacientes durante o seguimento em longo prazo. Objetivo: Avaliar o impacto da DAPE e tratamento endoscópico pós-operatório no comportamento das varizes esofágicas e recidiva hemorrágica, de pacientes esquistossomóticos. Métodos: Foram estudados 36 pacientes com seguimento superior a cinco anos, distribuídos em dois grupos: queda da pressão portal abaixo de 30% e acima de 30% comparados com o calibre das varizes esofágicas no pós-operatório precoce e tardio além do índice de recidiva hemorrágica. Resultados: Após a DAPE houve diminuição significativa no calibre das varizes esofágicas que, durante o seguimento aumentaram de calibre e foram controladas com tratamento endoscópico. A queda da pressão portal não influenciou significativamente o comportamento do calibre das varizes no pós-operatório precoce nem tardio nem os índices de recidiva hemorrágica. Conclusão: A queda na pressão portal não influenciou significativamente a variação dos calibres das varizes ao comparar os diâmetros pré e pós-operatórios precoces ou tardios. A comparação entre a queda de pressão do portal e as taxas de ressangramento também não foi significativa.

ABSTRACT Background: The treatment of choice for patients with schistosomiasis with previous episode of varices is bleeding esophagogastric devascularization and splenectomy (EGDS) in association with postoperative endoscopic therapy. However, studies have shown varices recurrence especially after long-term follow-up. Aim: To assess the impact on behavior of esophageal varices and bleeding recurrence after post-operative endoscopic treatment of patients submitted to EGDS. Methods: Thirty-six patients submitted to EGDS were followed for more than five years. They were divided into two groups, according to the portal pressure drop, more or less than 30%, and compared with the behavior of esophageal varices and the rate of bleeding recurrence. Results: A significant reduction on the early and late post-operative varices caliber when compared the pre-operative data was observed despite an increase in diameter during follow-up that was controlled by endoscopic therapy. Conclusion: The drop in portal pressure did not significantly influence the variation of variceal calibers when comparing pre-operative and early or late post-operative diameters. The comparison between the portal pressure drop and the rebleeding rates was also not significant.

RESUMO O carcinoma hepatocelular (CHC) é uma das principais causas de mortalidade relacionada a câncer no Brasil e no mundo. A Sociedade Brasileira de Hepatologia (SBH) publicou em 2015 suas primeiras recomendações sobre a abordagem do CHC. Desde então, novas evidências sobre o diagnóstico e tratamento do CHC foram relatadas na literatura médica, levando a diretoria da SBH a promover uma reunião monotemática sobre câncer primário de fígado em agosto de 2018 com o intuito de atualizar as recomendações sobre o manejo da neoplasia. Um grupo de experts foi convidado para realizar uma revisão sistemática da literatura e apresentar uma atualização baseada em evidências científicas visando que pudesse nortear a prática clínica multidisciplinar do CHC. O texto resultante foi submetido a avaliação e aprovação de todos membros da SBH através de sua homepage. O documento atual é a versão final que contêm as recomendações atualizadas e revisadas da SBH.

ABSTRACT Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related mortality worldwide. The Brazilian Society of Hepatology (SBH) published in 2015 its first recommendations about the management of HCC. Since then, new data have emerged in the literature, prompting the governing board of SBH to sponsor a single-topic meeting in August 2018 in São Paulo. All the invited experts were asked to make a systematic review of the literature reviewing the management of HCC in subjects with cirrhosis. After the meeting, all panelists gathered together for the discussion of the topics and the elaboration of updated recommendations. The text was subsequently submitted for suggestions and approval of all members of the Brazilian Society of Hepatology through its homepage. The present manuscript is the final version of the reviewed manuscript containing the recommendations of SBH.

RESUMO Racional: Com a disseminação da cirurgia hepática minimamente invasiva tem-se observado nos últimos anos número crescente de trabalhos que demonstram seus potencias benefícios. No entanto, a maior parte da evidência disponível provém de estudos observacionais retrospectivos sujeitos a vieses, em especial, os de seleção. Além disso, em muitas casuísticas são incluídas no mesmo grupo diversas modalidades de operações minimamente invasivas. Objetivo: Comparar os resultados perioperatórios (até 90 dias) de pacientes submetidos a ressecções hepáticas totalmente laparoscópicas com pacientes contemporâneos por cirurgias abertas, pareados por pontuação de propensão (propensity score matching PSM), submetidos a ressecções hepáticas convencionais. Método: Foram estudados pacientes adultos consecutivos submetidos à ressecção hepática. Para homogeneização dos grupos foi utilizado pareamento por pontuação de propensão, utilizando a variável idade, gênero, tipo de doença (benigna vs. maligna), tipo de hepatectomia (maior vs. menor) e presença de cirrose. A partir disto, os grupos foram redefinidos com proporção 1:1, pelo método nearest. Resultado: Após o pareamento foram incluídos 120 pacientes em cada grupo. Os submetidos à operação totalmente laparoscópica apresentaram menor tempo cirúrgico (286,8±133,4 vs. 352,4±141,5 min, p<0,001), menor tempo de internação em unidade de terapia intensiva (1,9±1,2 vs. 2,5±2,2dias, p=0,031), menor tempo de internação hospitalar (5,8±3,9 vs. 9,9±9,3dias, p<0,001) e redução de 45% nas complicações perioperatórias (19,2 vs. 35%, p=0,008). Conclusão: As ressecções hepáticas totalmente laparoscópicas são exequíveis, seguras e associadas à menor tempo operatório, menor tempo de internação em unidade de terapia intensiva e internação hospitalar, além de diminuição nas complicações perioperatórias.

ABSTRACT Background: There have been an increasing number of articles that demonstrate the potential benefits of minimally invasive liver surgery in recent years. Most of the available evidence, however, comes from retrospective observational studies susceptible to bias, especially selection bias. In addition, in many series, several modalities of minimally invasive surgery are included in the same comparison group. Aim: To compare the perioperative results (up to 90 days) of patients submitted to total laparoscopic liver resection with those submitted to open liver resection, matched by propensity score matching (PSM). Method: Consecutive adult patients submitted to liver resection were included. PSM model was constructed using the following variables: age, gender, diagnosis (benign vs. malignant), type of hepatectomy (minor vs. major), and presence of cirrhosis. After matching, the groups were redefined on a 1:1 ratio, by the nearest method. Results: After matching, 120 patients were included in each group. Those undergoing total laparoscopic surgery had shorter operative time (286.8±133.4 vs. 352.4±141.5 minutes, p<0.001), shorter ICU stay (1.9±1.2 vs. 2.5±2.2days, p=0.031), shorter hospital stay (5.8±3.9 vs. 9.9±9.3 days, p<0.001) and a 45% reduction in perioperative complications (19.2 vs. 35%, p=0.008). Conclusion: Total laparoscopic liver resections are safe, feasible and associated with shorter operative time, shorter ICU and hospital stay, and lower rate of perioperative complications.

Abstract: En | Text: En | PDF: En

More than 18 million people in 188 countries have been diagnosed as having coronavirus disease (COVID-19), and COVID-19 has been responsible for more than 600,000 deaths worldwide. Brazil is now the second most affected country globally. Faced with this scenario, various public health measures and changes in the daily routines of hospitals were implemented to stop the pandemic. Patients with hepatocellular carcinoma (HCC) are at an increased risk for severe COVID-19 as they present with two major diseases: cancer and concomitant chronic liver disease. The COVID-19 pandemic can significantly impact the management of HCC patients from diagnosis to treatment strategies. These patients need special attention and assistance at this time, especially since treatment for tumors cannot be delayed in most cases. The aim of this guideline was to standardize the management of HCC patients during the COVID-19 pandemic. This document was developed, on the basis of the best evidence available, by a multidisciplinary team from Instituto do Câncer do Estado de São Paulo (ICESP), and Instituto Central of the Hospital das Clínicas da Universidade de São Paulo (HC-FMUSP), which are members of the São Paulo Clínicas Liver Cancer Group.

RESUMO CONTEXTO: A esquistossomose é um problema de saúde pública endêmico, afetando cerca de quatro milhões de pessoas. A forma hepato-esplênica da doença é caracterizada por fibrose peri-portal, hipertensão pré-sinusoidal e esplenomegalia. A função hepática está preservada, sendo o sangramento por varizes a principal complicação da afecção. O tratamento cirúrgico usado pela maioria dos serviços para prevenção do ressangramento é a desconexão ázigo-portal e esplenectomia. Muitos autores reportaram melhores resultados com a associação do tratamento cirúrgico e o tratamento endoscópico pós-operatório. OBJETIVO: O objetivo deste estudo foi comparar a queda da pressão portal intraoperatória com o comportamento das varizes esofagianas e as taxas de ressangramento em pacientes submetidos a tratamento cirúrgico e endoscópico pós-operatório após seguimento de longo prazo. MÉTODOS: Foi realizado um estudo retrospectivo de 36 pacientes esquistossomóticos com pelo menos um episódio de sangramento prévio por ruptura de varizes esofagianas, submetidos a desconexão ázigo-portal e esplenectomia, associada a tratamento endoscópico pós-operatório das varizes. Os pacientes foram divididos de acordo com a queda da pressão portal intraoperatória em dois grupos: redução menor e maior que 30%. Foram avaliadas a presença de tamanho das varizes a longo prazo e a recorrência do sangramento. RESULTADOS: Levando-se em conta o comportamento das varizes, não foi observada influência significativa em ambos os grupos de queda de pressão portal. Com relação ao ressangramento das varizes, embora três vezes mais frequente no grupo com menor queda de pressão portal, não foi observada diferença estatística. Todos pacientes foram submetidos a tratamento endoscópico pós-operatório. CONCLUSÃO: A ligadura elástica das varizes esofagianas, mais do que a queda da pressão portal, parece ser o principal fator responsável pelos bons resultados após a combinação das duas terapias (cirúrgica e endoscópica) para pacientes com hipertensão portal devido à esquistossomose. Estudos futuros serão necessário para confirmar esta hipótese.

ABSTRACT BACKGROUND: Schistosomiasis is an endemic health problem affecting about four million people. The hepatosplenic form of the disease is characterized by periportal hepatic fibrosis, pre-sinusoidal portal hypertension and splenomegaly. Liver function is preserved, being varices bleeding the main complication of the disease. The surgical treatment used in the majority of centers for the prevention of rebleeding is esophagogastric devascularization and splenectomy. Most authors reported better results with the association of surgical and postoperative endoscopic treatment. OBJECTIVE: The aim of this study was to compare the intra operative portal pressure decrease and esophageal varices behavior and rebleeding rates in patients submitted to surgical and postoperative endoscopic treatment after long-term follow-up. METHODS: A retrospective study of 36 patients with schistosomiasis with, at least, one previous bleeding from esophageal varices rupture submitted to esophagogastric devascularization and splenectomy, added to endoscopic varices postoperative treatment was performed. Patients were stratified according to the intra operative portal pressure decrease in two groups: reduction below and above 30%. Long-term varices presence, size and bleeding recurrence were evaluated. RESULTS: Regarding varices behavior, no significant influence was observed in both groups of portal pressure fall. Regarding bleeding recurrence, despite three times more frequent in the group with lower portal pressure fall, no significant difference was observed. All patients were submitted to postoperative endoscopic treatment. CONCLUSION: Esophageal varices banding, rather than portal pressure decrease, seems to be the main responsible factor for good results after combination of two therapies (surgery and endoscopy) for patients with portal hypertension due to schistosomiasis; further studies are necessary to confirm this hypothesis.

RESUMO Racional: A cirurgia hepática se desenvolveu significativamente nas últimas décadas. No Brasil, apesar do crescente interesse pela cirurgia do fígado, não há estudos a respeito da sua prática no país. Assim, foi realizada uma pesquisa do tipo inquérito, apropriada para estudos descritivos, permitindo entender adequadamente o cenário atual nacional. Objetivo: Obter uma visão abrangente da cirurgia hepática no Brasil, com foco no perfil dos grupos, técnicas operatórias e disponibilidade de recursos. Método: De abril a novembro de 2016, foi realizado um inquérito nacional sobre o perfil da cirurgia hepática no Brasil, composta por 28 questões relativas às características das equipes cirúrgicas, preferências técnicas, volume cirúrgico, resultados e disponibilidade de recursos nas instituições. A pesquisa foi enviada por e-mail para 84 cirurgiões hepáticos brasileiros líderes de seus respectivos grupos, abrangendo todas as regiões do país. Resultados: Quarenta e três participantes (51.2%) responderam à pesquisa (42 respostas completas e uma incompleta) de todas as regiões do Brasil. A maioria dos centros tem programa de residência (86%) e faz procedimentos por via laparoscópica (91%); a despeito da laparoscopia corresponder a uma pequena porcentagem das operações (1-9% dos procedimentos são laparoscópicos em 39,5% dos grupos). Apenas sete centros (16.3%) realizam mais do que 50 resecções hepáticas/ano. A taxa de mortalidade pós-operatória é de 1-3% em 55% dos centros. Conclusão: Esta é a primeira avaliação da cirurgia hepática no Brasil e indica que as práticas cirúrgicas estão alinhadas com centros de excelência mundiais, concentradas em hospitais dedicados à prática acadêmica.

ABSTRACT Background: Liver surgery has developed significantly in the past decades. In Brazil, the interest on it has grown significantly, but there is no study regarding its clinical practice. Despite intrinsic limitations, surveys are well suited to descriptive studies and allow understanding the current scenario. Aim: To provide an overview on the current spread of liver surgery in Brazil, focusing on groups´ profile, operative techniques and availability of resources. Method: From May to November 2016, was conducted a national survey about liver surgery profile in Brazil composed by 28 questions concerning surgical team characteristics, technical preferences, surgical volume, results and available institutional resources. The survey was sent by e-mail to 84 liver surgery team leaders from different centers including all regions of the country. Results: Forty-three study participants (51.2%), from all Brazilian regions, responded the survey. Most centers have residency/fellowship programs (86%), perform and do laparoscopic procedures (91%); however, laparoscopy is still responsible for a little amount of surgeries (1-9% of laparoscopic procedures over all liver resections in 39.5% of groups). Only seven centers (16.3%) perform more than 50 liver resections/year. Postoperative mortality rate is between 1-3% in 55% of the centers. Conclusion: This is the first depiction of liver surgery in Brazil. It showed a surgical practice aligned with worldwide excellence centers, concentrated on hospitals dedicated to academic practice.
