RESUMO
Antibiotic prophylaxis in patients with cirrhosis and acute variceal bleeding is part of the standard of care according to most clinical guidelines. However, with recent evidence arguing against antibiotic prophylaxis, the role of this intervention has become less clear.

We describe the case of a 61-year-old male patient with a history of hemophilia A and previous hepatitis C virus infection with sustained virological response and no previous documentation of cirrhosis, who was admitted for variceal bleeding. He was taken for endoscopic evaluation with evidence of active variceal hemorrhage requiring rubber band ligation. Patients with congenital coagulation disorders, such as hemophilia A, are excluded from international guidelines for gastrointestinal bleeding, making their management and counseling challenging. In this article, we describe the specific interventions to be performed in patients with hemophilia A and upper gastrointestinal tract bleeding, specifically variceal bleeding, focusing on pre-endoscopic and endoscopic management.
RESUMO
ABSTRACT Background: Most data on the natural history of portal hypertension come from studies in adults. The morbidity rate of upper gastrointestinal bleeding (UGIB) in children with portal hypertension has not been systematically characterized. Objective: To describe the morbidity and mortality of UGIB in pediatric patients with portal hypertension and identify predictive factors for the occurrence of its main complications. Methods: This retrospective study included pediatric patients with cirrhotic portal hypertension or with extrahepatic portal vein obstruction (EHPVO). Mortality and UGIB complications within a period of up to 6 weeks of the bleeding were investigated. To determine the predictive factors of morbidity, a multivariate analysis was performed using logistic regression; all results were considered significant at P<0.05. Results: A total of 86 patients (51.2% with EHPVO and 48.8% with cirrhosis) had 174 bleeding events. Ascites was the most common complication (43.1% of all cases), being more prevalent in patients with cirrhosis (P<0.001). Cirrhosis was a predictor of the occurrence of any morbidity (OR 20.3). The need for blood transfusion was predictor of at least one complication (OR 5.8), ascites (OR 7.2) and infections (OR 3.8) in the general group and at least one complication (OR 11.3) and ascites (OR 5.8) in cirrhotic patients. The need for expansion was a predictor of any morbidity (OR 4.6) and infections (OR 3.9) in the general group, in addition to being predictor of infection in cirrhotic patients (OR 5.4). There were no deaths from UGIB in the six weeks post-bleeding. Conclusion: The study showed the relevance of morbidity after UGIB in pediatric patients with portal hypertension, especially in those with cirrhosis. The patients with hemodynamic instability requiring blood transfusion or expansion on admission are at increased risk of complications related to upper gastrointestinal bleeding and should be closely monitored.
RESUMO Contexto: A maioria dos dados sobre a história natural da hipertensão porta provém de estudos em adultos. A morbidade associada à hemorragia digestiva alta (HDA) em crianças com hipertensão porta ainda não foi sistematicamente estudada. Objetivo: Descrever a morbimortalidade da HDA em pacientes pediátricos com hipertensão porta e identificar fatores preditivos para a ocorrência de suas principais complicações. Métodos: Este estudo retrospectivo incluiu pacientes pediátricos com hipertensão porta cirrótica ou com obstrução extra-hepática da veia porta (OEHVP). A mortalidade e as complicações da HDA foram estudadas até seis semanas após o sangramento. Para determinar os fatores preditivos de morbidade, foi realizada análise multivariada por meio de regressão logística; todos os resultados foram considerados significativos com P<0,05. Resultados: Oitenta e seis pacientes (51,2% com OEHVP e 48,8% com cirrose) tiveram 174 eventos hemorrágicos. A ascite foi a complicação mais comum (43,1% de todos os casos), sendo mais prevalente em pacientes com cirrose (P<0,001). A cirrose foi preditor da ocorrência de pelo menos uma complicação (OR 20,3). A necessidade de transfusão sanguínea foi preditora de pelo menos uma complicação (OR 5,8), ascite (OR 7,2) e infecções (OR 3,8) no grupo geral e pelo menos uma complicação (OR 11,3) e ascite (OR 5,8) nos cirróticos. A necessidade de expansão foi preditor de qualquer morbidade (OR 4,6) e infecções (OR 3,9) no grupo geral, além de ser preditor de infecção em cirróticos (OR 5,4). Não houve óbitos por HDA nas 6 semanas pós-sangramento. Conclusão: O estudo mostrou a relevância da morbidade após HDA em pacientes pediátricos com hipertensão porta, principalmente naqueles com cirrose. Os pacientes com instabilidade hemodinâmica que necessitam de transfusão de sangue ou expansão na admissão têm risco aumentado de complicações relacionadas à hemorragia digestiva alta e devem ser monitorados de perto.
RESUMO
Cirrhosis is the end-stage of chronic liver disease and constitutes a leading cause of potential years of working life lost, especially in the Americas and Europe. Its natural history is characterized by an asymptomatic phase called compensated cirrhosis, followed by a rapidly progressive phase characterized by liver-related complications termed decompensated cirrhosis. Complications could be related to portal hypertension and/or liver dysfunction, including ascites, portal hypertensive gastrointestinal bleeding, encephalopathy, and jaundice. This review will discuss some of the most important precipitants of hepatic decompensation, including acute variceal bleeding, spontaneous bacterial peritonitis, and hepatic encephalopathy.

INTRODUCTION: Portal hypertension (PHT) and its complications in children are thought to be distinct from adult PHT in several areas, including the underlying bio-physiology of a child in which PHT develops, but also because of the pediatric-specific etiologies that drive disease progression. And yet pharmacologic approaches to PHT in children are mainly based on adult data, modified for pediatric practice. This reality has been driven by a lack of data specific to children. AREAS COVERED: The authors discuss current therapeutic approaches to PHT in children, including management of acute gastrointestinal variceal bleed, pharmacotherapy in prophylaxis, and established and emerging therapies to combat systemic co-morbidities that result from PHT. The few areas where pediatric-specific data exist are highlighted and the many gaps in knowledge that remain unresolved are underscored. EXPERT OPINION: Despite decades of experience, optimal management of pediatric PHT remains undefined. In large part, this can be directly linked to a lack of basic understanding related to the unique pathophysiology and natural history that defines PHT in children. As a result, meaningful research into the utility and effectiveness of pharmacotherapy in children with PHT remains in its infancy. Large, multi-center, prospective studies will be needed to begin to establish an infrastructure on which a pediatric-specific research agenda can be built.

OBJECTIVES: Acute variceal bleeding (AVB) results from rupture of esophageal or gastric varices. It is a life-threatening complication of portal hypertension. Nevertheless, it remains unclear how to predict adverse outcomes and identify high-risk patients. In variceal hemorrhage, high Child-Turcotte-Pugh (Child) and Model for End-stage Liver Disease (MELD) scores are associated with a worse prognosis. The Rockall system (Rockall), Glasgow-Blatchford (Blatchford), and AIMS65 scores have been validated for risk stratification for nonvariceal upper gastrointestinal bleeding; however, their use is controversial in AVB. The aim of this study was to compare the performance of Child, MELD, Rockall, Blatchford, and AIMS65 scores in risk stratification for rebleeding and/or mortality associated with AVB. METHODS: This retrospective study was conducted at a tertiary care hospital over 42 months. The outcomes were 6-week rebleeding and mortality. The AUROC was calculated for each score (1-0.9, 0.9-0.8, and 0.8-0.7, indicating excellent, good, and acceptable predictive power, respectively). RESULTS: In total, 222 patients were included. Six-week rebleeding and mortality rates were 14% and 18.5%, respectively. No score was useful for discriminating patients at a higher risk of rebleeding. The AUROCs were 0.59, 0.57, 0.61, 0.63, and 0.56 for Rockall, Blatchford, AIMS65, Child, and MELD scores, respectively. Prediction of 6-week mortality based on Rockall (AUROC 0.65), Blatchford (AUROC=0.60), and AIMS65 (AUROC=0.67) scores were also not considered acceptable. The AUROCs for predicting mortality were acceptable for Child and MELD scores (0.72 and 0.74, respectively). CONCLUSION: Rockall, Blatchford, and AIMS65 scores are not useful for predicting 6-week rebleeding or mortality in patients with AVB. Child and MELD scores can identify patients at higher risk for 6-week mortality but not for 6-week rebleeding.

Gastroesophageal variceal bleeding is a life-threatening complication in patients with liver cirrhosis and portal hypertension. The endoscopic injection of cyanoacrylate is considered as the first-line alternative for gastric varices treatment; however, the incidence of adverse events supports the endoscopic ultrasound-guided approach. Endoscopic ultrasound-guided interventions are a safe and feasible technique for the injection of sclerosants, cyanoacrylate, thrombin, and the deployment of coils into targeted vessels. This review article aims to offer an overview of the role of endoscopic ultrasound-guided vascular therapy and present the available data regarding endoscopic ultrasound-guided management of gastrointestinal bleeding and other vascular therapies. The available data have shown the superiority of endoscopic ultrasound-guided endovascular therapy over the endoscopic technique, which supports the implementation of endoscopic ultrasound-guided therapy in therapeutical algorithms and guidelines. Regarding whether injecting cyanoacrylate, the deployment of coils, or combined therapy, we recommend the endoscopic ultrasound-guided combined therapy in patients with gastric varices due to the high eradication rate with lower rebleeding and reintervention rates. Multicenter worldwide studies are required to confirm the actual clinical applicability of endoscopic ultrasound-guided endovascular therapy and establish treatment algorithms. Endoscopic ultrasound offered a safe and effective alternative in the management of variceal and nonvariceal gastrointestinal bleeding, with the implementation of new diagnostic and treatment options for various gastrointestinal conditions, representing a new territory for research and development.
RESUMO
Variceal bleeding is a dramatic complication of cirrhosis. Primary prophylaxis against variceal bleeding is indicated for patients with high-risk varices. In order for these patients to be identified, endoscopic screening for esophageal varices has been traditionally recommended at the time of the diagnosis of cirrhosis. Considering that many patients do not have esophageal varices in the early stages of cirrhosis and, therefore, are submitted to endoscopy unnecessarily, non-invasive methods for variceal screening have been studied. Among these non-invasive methods, the most extensively studied probably are platelet count/spleen diameter ratio, liver stiffness, spleen stiffness and an association between liver stiffness and platelet count, referred to as the Baveno VI criteria. The Baveno VI criteria has recently been recommended by different medical associations for variceal screening. This is a critical review on the non-invasive methods for variceal screening, in which the performances of the different methods are presented and the limitations of the existing evidence is discussed. Despite reasonable performances of some of these methods, especially platelet count/spleen diameter ratio and the association between liver stiffness and platelet count, we understand that the available evidence still has relevant limitations and that physicians should decide on screening cirrhotic patients for esophageal varices with endoscopy or non-invasive methods on a case-by-case basis.

OBJECTIVE: To report the results of endoscopic ultrasound-guided injection of coils with cyanoacrylate (CYA) using a less-expensive coil with an emphasis on the roles of Doppler and endosonographic varicealography (EV) in identifying the feeder vessel in gastric varix treatment. METHODS: An observational, descriptive study with prospectively collected data. Patients with gastric varices (GV) were included and were treated by endoscopic ultrasound-guided injection of CYA and a less-expensive coil. Technical success, complete and immediate variceal obliteration, rebleeding, complication and survival rates were evaluated. RESULTS: Thirty patients with GV with a mean age of 62 years (range: 44-76 years) were treated. Median number of coils used was 2 (range: 1-3), and median volume of CYA was 1.8 mL (1.2-2.4 mL). Technical success rate was 100%. EV technical success was observed in 26/30 patients. Complete variceal obliteration was observed in 96.6% of patients, and immediate disappearance of the varix was observed in 24 (80%) patients. The complication rate was 6.7%. CONCLUSIONS: Endoscopic-ultrasound guidance for gastric varix treatment with the addition of EV and the use of a less-expensive coil is a safe and effective technique that results in the immediate disappearance of GV after targeting the feeding vessel.

Resumen El sangrado varicoso es una urgencia médica con altas tasas de morbimortalidad. De los pacientes que llegan para recibir manejo hospitalario, hasta un 10% no responden a medidas hemostáticas convencionales, por lo que se ha planteado el uso de prótesis metálicas autoexpandibles para el manejo con resultados prometedores de dichos pacientes. En el presente documento se discute la literatura mundial disponible acerca de la experiencia en el uso de dichos dispositivos; la eficacia en el control agudo; el pronóstico a largo plazo; el tipo de prótesis utilizadas y las alternativas, complicaciones y retos del manejo de pacientes con esta técnica, que puede considerarse emergente en nuestro medio.
Abstract Variceal bleeding is a medical emergency which has high rates of morbidity and mortality. Up to 10% of these patients treated in hospitals do not respond to conventional hemostatic measures. For this reason, the use of self-expanding metal stents (SEMS) has been proposed for management of these patients. It has had promising results. This paper discusses the literature available internationally about experience with the use of SEMS, their efficacy for acute control, long-term patient prognoses, types of stents, alternatives, complications, and challenges for the use of SEMS for patient management that should be considered in our environment.

PURPOSE OF REVIEW: The purpose of this study is to analyze the current evidence regarding the use of statins in patients with chronic liver disease and cirrhosis. RECENT FINDINGS: Chronic liver disease (CLD), cirrhosis, and its complications, including hepatocellular carcinoma (HCC), are significant public health problems. The use of statins in patients with CLD has been a matter of concern, and physicians are often reluctant to its prescription in these patients. This mainly relates to the potential occurrence of drug-induced liver injury. However, newer evidence from pre-clinical and clinical research has shown that statins are drugs with a potentially beneficial impact on the natural history of cirrhosis, on portal hypertension, and in HCC prevention. In this review, we summarize current evidence regarding the influence of statins in endothelial dysfunction in CLD, their ability to modulate hepatic fibrogenesis, and their vasoprotective effects in portal hypertension; we also focus on existing data about the impact of statins in cirrhosis development, progression, and complications and critically assess the current concerns about its use in patients with CLD.

Resumen: Introducción: Hemospray® es un nuevo dispositivo para hemostasia endoscópica utilizado para el sangrado gastrointestinal no variceal. Permite la hemostasia mediante la activación plaquetaria y el aumento de la concentración de factores de coagulación, así como la formación de una barrera mecánica sobre la pared de un vaso sangrante creando un tapón mecánico en el sitio de sangrado. Dentro de las principales indicaciones para su uso se encuentran lesiones de difícil acceso endoscópico, hemorragia gastrointestinal masiva, múltiples sitios de sangrado, modificación de la anatomía por terapia endoscópica previa, presencia de coagulopatía, dificultad para tener visualización directa o cuando es imposible tener contacto con la lesión sangrante. Sin embargo, su uso en niños aún no ha sido aprobado por la FDA. Existe un caso publicado de un paciente de 11 meses tratado exitosamente con Hemospray® por hemorragia gastrointestinal no variceal. Caso clínico: Se reporta el caso de una paciente de 2 años con falla hepática aguda y cirrosis biliar primaria con hipertensión portal y sangrado post-escleroterapia. Se analizó el caso para sustentar las nuevas terapias para el control del sangrado masivo en úlceras post-escleroterapia. Conclusiones: La aplicación demostró ser segura y sin efectos adversos. El uso de Hemospray® es una alternativa efectiva en el control del sangrado gastrointestinal.
Abstract: Background: Hemospray® is a new device for endoscopic hemostasis used for non-variceal gastrointestinal bleeding. It enables hemostasis and platelet activation by increasing the concentration of clotting factors and forming a mechanical barrier on the wall of a bleeding vessel creating a mechanical plug at the site of bleeding. Within the main indications for use are: injuries with difficult endoscopic access, massive gastrointestinal bleeding, multiple bleeding sites, modification of the anatomy by previous endoscopic therapy, presence of coagulopathy, difficulty in having direct visualization or when it is impossible to have contact with the bleeding lesion. However, its use in children has not been approved yet by the FDA. There is a case report of an 11-month-old patient successfully treated with Hemospray® for non-variceal gastrointestinal bleeding. Clinical case: We report the case of a 2-year-old female with acute liver failure and primary biliary cirrhosis with portal hypertension and bleeding after sclerotherapy. We analyzed the case to support new therapies for massive bleeding control in post-sclerotherapy esophageal ulcers. Conclusions: The application showed to be safe without side effects. Using Hemospray® is an effective alternative in controlling gastrointestinal bleeding.
RESUMO
Transjugular intrahepatic portosystemic shunt creation is a well-established therapy for refractory variceal bleeding and refractory ascites in patients who do not tolerate repeated large volume paracentesis. Experience and technical improvements including covered stents have led to improved TIPS outcomes that have encouraged an expanded application. Evidence for other less frequent indications continues to accumulate, including the indications of primary prophylaxis in patients with high-risk acute variceal bleeding, gastric and ectopic variceal bleeding, primary treatment of medically refractory ascites, recurrent refractory ascites following liver transplantation, hepatic hydrothorax, hepatorenal syndrome, Budd-Chiari syndrome, and portal vein thrombosis. Treatment of patients with high-risk acute variceal bleeding with early TIPS and using transjugular intrahepatic portosystemic shunts as a primary therapy rather than large volume paracentesis for refractory ascites would likely be the 2 circumstances that permit expansion in the frequency of TIPS procedures. The remaining populations discussed above are relatively rare.

RESUMO
AIM: To propose a less invasive surgical treatment for schistosomal portal hypertension. METHODS: Ten consecutive patients with hepatosplenic schistosomiasis and portal hypertension with a history of upper gastrointestinal hemorrhage from esophageal varices rupture were evaluated in this study. Patients were subjected to a small supraumbilical laparotomy with the ligature of the splenic artery and left gastric vein. During the procedure, direct portal vein pressure before and after the ligatures was measured. Upper gastrointestinal endoscopy was performed at the 30(th) postoperative day, when esophageal varices diameter were measured and band ligature performed. During follow-up, other endoscopic procedures were performed according to endoscopy findings. RESULTS: There was no intra-operative mortality and all patients had confirmed histologic diagnoses of schistosomal portal hypertension. During the immediate postoperative period, two of the ten patients had complications, one characterized by a splenic infarction, and the other by an incision hematoma. Mean hospitalization time was 4.1 d (range: 2-7 d). Pre- and post-operative liver function tests did not show any significant changes. During endoscopy thirty days after surgery, a decrease in variceal diameters was observed in seven patients. During the follow-up period (57-72 mo), endoscopic therapy was performed and seven patients had their varices eradicated. Considering the late postoperative evaluation, nine patients had a decrease in variceal diameters. A mean of 3.9 endoscopic banding sessions were performed per patient. Two patients presented bleeding recurrence at the late postoperative period, which was controlled with endoscopic banding in one patient due to variceal rupture and presented as secondary to congestive gastropathy in the other patient. Both bleeding episodes were of minor degree with no hemodynamic consequences or need for blood transfusion. CONCLUSION: Ligature of the splenic artery and left gastric vein with supraumbilical laparotomy is a promising and less invasive method for treating presinusoidal schistosomiasis portal hypertension.

One of the most relevant complications of portal hypertension in cirrhosis is the development of gastroesophageal varices. They are present in 50 percent of patients with cirrhosis at the diagnosis. The risk of bleeding depends on the degree of portal hypertension and the severity of liver disease. Variceal hemorrhage is the most common lethal complication of cirrhosis. In the last decades there had been numerous clinical trials involving different treatment options for variceal bleeding (pharmacological, endoscopic and surgery) trying to establish the best treatment strategy. Since the rise in portal pressure is the cause of variceal rupture, therapies that can decrease portal pressure have a theoretical rationale for their use. Endoscopic treatment, although effective, has no effect on portal pressure. Vasoactive agents (vasopressin and its analogue terlipressin, somatostatin and its analogue octreotide) cause splanchnic vasoconstriction and decrease portal pressure. Pharmacological treatments have the advantage that they can be easily administered, and started as soon as the diagnosis of variceal bleeding is suspected. This makes pharmacological treatment especially attractive for centers that have no chance of emergency endoscopy. At this moment there is sufficient evidence to recommend combined treatment with vasoactive drugs and endoscopy for the control of variceal hemorrhage.
Una de las principales complicaciones de los pacientes cirróticos con hipertensión portal es el desarrollo de várices gastroesofágicas. Éstas están presentes al momento del diagnóstico en alrededor de 50 por ciento de los pacientes con cirrosis. La hemorragia variceal es la complicación letal más frecuente en los pacientes cirróticos. En las últimas décadas se han realizado múltiples esfuerzos para lograr definir la mejor combinación de técnicas (endoscópicas, farmacológicas y quirúrgicas) para disminuir la morbimortalidad asociada a la hemorragia variceal. Dado que la causa de la ruptura de las várices es un aumento de la presión portal, todas las medidas que logren disminuirla son medidas racionales para lograr detener la hemorragia. El tratamiento endoscópico, si bien efectivo, no afecta la fisiopatología de la hemorragia variceal. Las drogas vasoconstrictoras (vasopresina y su derivado terlipresina o somatostatina y su derivado octreotide) actúan a nivel de la circulación esplácnica, disminuyendo el flujo sanguíneo. El tratamiento farmacológico tiene la ventaja de ser fácilmente administrado, incluso antes de realizar una endoscopia, toda vez que se sospecha una hemorragia variceal, lo que hace particularmente atractivo su uso en centros en que no se cuenta con endoscopia de urgencia. Actualmente, existe suficiente evidencia para recomendar el uso de estos fármacos como terapia adicional a la endoscopia ante la sospecha de una hemorragia variceal.

Variceal bleeding is a severe complication of portal hypertension, associated to hepatic cirrhosis. It is more frequent in esophageal varices than in gastric varices. The first-line treatment is resuscitation, careful intravenous saline fluids infusions, prophylactic antibiotics and early combined use of vasoactive drugs and endoscopic therapy. Despite these measures, haemostasis failure is of 20 percent after 6 weeks. In these patients, the second-line treatment is transjugular intrahepatic portosystemic shunt (TIPS), procedure that requires an interventional radiologist. Therapeutic options are evaluated for bleeding esophageal varices, such as TIPS with covered stent as first-line treatment, portosystemic shunt surgery in Child-Pugh A patients as alternative to TIPS, the use of recombinant FVII in massive bleeding established by endoscopy and selfexpandable metallic stent in Child-Pugh B-C patients, instead of balloon. For gastric varices the use of balloon retrograde transvenous occlusion (BRTO) is described.
El sangrado variceal es una complicación grave de la hipertensión portal asociada a cirrosis hepática. Es más frecuente en várices esofágicas que gástricas. Como primera línea de tratamiento está la resucitación, volemización cuidadosa, profilaxis antibiótica y el uso combinado precoz de drogas vasoactivas junto a terapia endoscópica. A pesar de estas medidas, la hemostasia fracasa hasta en 20 por ciento a 6 semanas. En estos pacientes, la segunda línea de tratamiento es el Cortocircuito intrahepático portosistémico transyugular (Transjugular Intrahepatic Portosystemic Shunt- TIPS), procedimiento que requiere la participación de un radiólogo intervencionista. Se evalúan opciones terapéuticas para várices esofágicas sangrantes como el TIPS con stent recubierto usado de primera línea, la cirugía de shunt portosistémico en pacientes Child A como alternativa al TIPS, el uso de FVII recombinante en sangrado variceal masivo detectado mediante endoscopia, y el stent metálico autoexpandible en Child B-C en vez de balón. Para várices gástricas se describe el uso del balón oclusivo retrógrado transvenoso (B-RTO).

Nas últimas duas décadas, foi observada redução importante na mortalidade associada ao primeiro sangramento varicoso, que vem sendo atribuída à melhoria na assistência ao paciente cirrótico e à abordagem multidisciplinar do paciente com hemorragia digestiva alta varicosa (HDAV), particularmente por emergencistas, hepatologistas, gastroenterologistas, endoscopistas e intensivistas. Visando estabelecer recomendações para o manejo da HDAV, a Sociedade Brasileira de Hepatologia (SBH) realizou reunião de consenso para elaboração de documento a ser utilizado como orientação de conduta médica. Dentro da sistemática utilizada, foi criada pela SBH uma comissão organizadora composta por quatro membros que escolheram 27 pesquisadores, representando as diversas regiões do país, para serem moderadores ou expositores dos tópicos relacionados à prevenção, diagnóstico e tratamento da HDAV. Todos os tópicos foram abordados de acordo com o grau de evidência científica disponível. As recomendações foram elaboradas em reunião após ampla discussão com os membros da comissão organizadora, expositores, moderadores e participantes da reunião do consenso, ficando a cargo da comissão organizadora a redação do documento final. A reunião do consenso ocorreu em Salvador em 06 de maio de 2009 e esta publicação exibe as principais conclusões do consenso organizadas sob a forma de resumo da literatura médica seguido pelas recomendações da SBH.
In the last decades, several improvements in the management of variceal bleeding have resulted in a significant decrease in morbidity and mortality of cirrhotis with bleeding varices. Progress in the multidisciplinary approach to the patient with variceal blleding has led to a better management of this disease by critical care physicians, hepatologists, gastroenterologists, endoscopists, radiologists and surgeons. In this respect, the Brazilian Society of Hepatology has, recently, sponsored a consensus meeting in order to draw evidence-based recommendations on the management of these difficult-totreat subjects. An organizing committee comprised of four people was elected by the Governing Board and was responsible to invite 27 researchers from distinct regions of the country to make a systematic review of the subject and to present topics related to variceal bleeding, including prevention, diagnosis, management and treatment, accoding to evidence-based medicine. After the meeting, all participants were held together for discussion of the topics and the elaboration of the aforementioned recommendations. The organizing committee was responsible for writing the final document. The meeting was held at Salvador, May 6th, 2009 and the present manucrispt is the summary of the systematic review that was presented during the meeting organized in topics followed by the reccomendations of the Brazilian Society of Hepatology.

In patients with cirrhosis and portal hypertension, variceal bleeding is a severe complication, and still a major cause of death. From 1986 to 2010 (Baveno V), several consensuses related to this topic have been carried out. The main purposes of these meetings were to develop clear definitions and therapeutic recommendations aimed at the standardization and increased ease of interpretation among different studies, to be homogeneous, which is essential for meta-analysis. This applies both to the definition of events related to variceal hemorrhage and therapeutic behaviour. In Baveno V some definitions were modified such as criteria for failure to control bleeding, and failure of secondary prophylaxis, while other definitions were validated. As in Baveno IV, the level of evidence (1 being the highest, 5 being the lowest) and the grades of recommendation (A the strongest, D the weakest) were assessed according to the Oxford System. Particular emphasis was placed on management of non-cirrhotic portal hypertension, especially on the Budd-Chiari syndrome and extra-hepatic portal vein obstruction. Areas requiring further study include mechanism in the development and progression of portal hypertension; the development of non-invasive techniques to identify patients with clinically significant portal hypertension; the assessment of the impact of the management of chronic liver disease in the development of this condition; the role of regular control of portal hypertension in the prevention of the development and progression of gastroesophageal varices. Finally more information about non-cirrhotic portal hypertension is needed, especially on the frequency, primary prophylaxis of variceal bleeding, factors associated with treatment failure, progression and thrombosis recurrence.
La hipertensión portal (HP) constituye un alteración hemodinámica severa, responsable de las principales complicaciones de la cirrosis, entre las cuales está la hemorragia por várices gastroesofágicas. Desde el año 1986 y hasta el 2010 (Baveno V), se han efectuado diferentes reuniones de consensos, cuyos objetivos han sido estandarizar criterios, haciéndolos simples y reproducibles, de tal forma de homogeneizar los resultados de estudios clínicos y meta-análisis. Esto es válido tanto para la definición de eventos relacionados con hemorragia variceal, como de conductas terapéuticas. En Baveno V se han modificado algunas definiciones como los criterios de falla en el control de la hemorragia, y de falla en la profilaxis secundaria, mientra que otras se validaron. Al igual que en Baveno IV, se utilizó el Sistema Oxford, para representar el nivel de evidencia (1 el mayor; 5 el menor) y de recomendación (A la más fuerte y D la de menor peso). Especial hincapié se ha hecho en el manejo de la HP de origen no cirrótica (Síndrome de Budd-Chiari y obstrucción de la vena porta extra-hepática). Finalmente, las áreas con desafíos en investigación clínica incluyen mecanismos en el desarrollo y progresión de la HP; empleo de medidas no invasivas para identificar pacientes con HP de significación; evaluación del impacto que tiene el manejo de la enfermedad hepática de base, en el desarrollo de esta complicación; el papel de la medición de la presión portal en la prevención del desarrollo y progresión de las várices gastroesofágicas. Finalmente, se recomienda realizar estudios prospectivos sobre prevalencia y evolución clínica de la HP no cirrótica y profilaxis primaria de la hemorragia variceal; identificación de la población de riesgo y de factores asociados con falla al tratamiento, progresión de la enfermedad y recurrencia.

Cirrosis hepática es una enfermedad prevalente en el mundo. Su diagnóstico y tratamiento debe ser dominio de todo médico general e internista. En los últimos años han ocurrido notables avances en el diagnóstico, fisiopatología, tratamiento y en la identificación de factores pronósticos de cirrosis y de sus complicaciones mayores. Particular atención ha existido en desarrollar medidas preventivas de sus complicaciones como por ejemplo: hemorragia por várices esofágicas, peritonitis bacteriana espontánea, síndrome hepatorrenal. Estas medidas preventivas han influido de forma muy favorable en el pronóstico de los pacientes cirróticos. En este artículo se discuten las diversas estrategias preventivas que han demostrado su efectividad en cirrosis hepática
Liver cirrhosis is a prevalent disease around the world. Its diagnosis and treatment must be in the knowledge of every general physicians and internist.Over the last years, there have been notorious advances in the diagnosis, pathophysiology, treatment and the identification of prognosis factors for cirrhosis major complications.There has been particular attention to the development of preventive measures for its complications, such as variceal bleeding, spontaneous bacterial peritonitis, hepatorenal syndrome. These preventive measures have had a favorable influence on the prognosis of cirrhotic patients. This article discusses several preventive strategies that have proven its effectiveness in hepatic cirrhosis
