Abstract
Acute upper and lower gastrointestinal (GI) bleeding may be a potentially life-threatening event that requires prompt recognition and an early effective management, being responsible for a considerable number of hospital admissions. Methods. We perform a clinical review to summarize the recent international guidelines, helping the physician in clinical practice. Older people are a vulnerable subgroup of patients more prone to developing GI bleeding because of several comorbidities and polypharmacy, especially related to an increased use of antiplatelet and anticoagulant drugs. In addition, older patients may have higher peri-procedural risk that should be evaluated. The recent introduction of reversal strategies may help the management of GI bleeding in this subgroup of patients. In this review, we aimed to (1) summarize the epidemiology and risk factors for upper and lower GI bleeding, (2) describe treatment options with a focus on pharmacodynamics and pharmacokinetics of different proton pump inhibitors, and (3) provide an overview of the clinical management with flowcharts for risk stratification and treatment. In conclusion, GI is common in older patients and an early effective management may be helpful in the reduction of several complications.

Abstract
PURPOSE OF REVIEW Enterocutaneous fistulas (ECFs) pose a significant impact in the healthcare system, both financially and in resource utilization. Delivery of optimal care is complex and involves intensive wound care, complex nutritional delivery and multidisciplinary care teams for optimization. Recently, there have been pushes to modernize the traditional approach to ECF care to a new paradigm of protocol-based individualized delivery of care. RECENT FINDINGS There is an increased trend towards pushing enteral nutrition for the management of ECF patients. Adjuncts, including improved fistuloclysis devices, supplements and absorptive aides have challenged the conventional dogma of ECF treatment. There has also been increased focus on surgical prehabilitation and the ability to improve patient outcomes. SUMMARY ECF care is complex and requires a multidisciplinary approach focused on source control, nutritional optimization with focus on enteral nutrition, wound care and prehabilitation.

Abstract
Cirrhosis is a liver disease that leads to increased intrahepatic resistance, portal hypertension (PH), and splanchnic hyperemia resulting in ascites, variceal bleeding, and hepatorenal syndrome. Terlipressin, a prodrug that converts to a short half-life vasopressin receptor 1 A (V1a) full agonist [8-Lys]-Vasopressin (LVP), is an intravenous treatment for PH complications, but hyponatremia and ischemic side effects require close monitoring. We developed PHIN-214 which converts into PHIN-156, a more biologically stable V1a partial agonist. PHIN-214 enables once-daily subcutaneous administration without causing ischemia or tissue necrosis and has a 10-fold higher therapeutic index than terlipressin in healthy rats. As V1a partial agonists, PHIN-214 and PHIN-156 exhibited maximum activities of 28 % and 42 % of Arginine vasopressin (AVP), respectively. The potency of PHIN-156 and LVP relative to AVP is comparable for V1a (5.20 and 1.65 nM, respectively) and V1b (102 and 115 nM, respectively) receptors. However, the EC50 of PHIN-156 to the V2 receptor was 26-fold higher than that of LVP, indicating reduced potential for dilutional hyponatremia via V2 agonism compared to terlipressin/LVP. No significant off-target binding to 87 toxicologically relevant receptors were observed when evaluated in vitro at 10 µM concentration. In bile duct ligated rats with PH, subcutaneous PHIN-214 reduced portal pressure by 13.4 % ± 3.4 in 4 h. These collective findings suggest that PHIN-214 could be a novel pharmacological treatment for patients with PH, potentially administered outside of hospital settings, providing a safe and convenient alternative for managing PH and its complications.

Abstract
Portal hypertension is a clinical syndrome defined by an increased portal venous pressure. The most frequent cause of portal hypertension is liver cirrhosis, and many of the complications of cirrhosis, such as ascites and gastroesophageal variceal bleeding, are related to portal hypertension. Portal hypertension is a pathological condition caused by the accumulation of blood flow in the portal system. This blood flow retention reduces the effective circulation volume. To compensate for these changes, neurotransmitter hormone changes and metabolic abnormalities occur, which cause complications in organs other than the liver. A hepatic hydrothorax is fluid accumulation in the pleural space resulting from increased portal pressure. Hepatopulmonary syndrome and portopulmonary hypertension are the pulmonary complications in cirrhosis by deforming the vascular structure. Symptoms, such as dyspnea and hypoxia, affect the survival and the quality of life of patients. These lung complications are usually underestimated in the management of cirrhosis. This review briefly introduces the type of lung complications of cirrhosis.

Abstract
Efficient and thorough care of hospitalized patients with advanced chronic liver disease is of utter importance to improve outcomes and optimize quality of life. This requires understanding current evidence and best practices. To facilitate focus on up-to-date knowledge and a practical approach, we have created the HEPA-ROUNDS mnemonic while outlining a practical review of the literature with critical appraisal for the busy clinician. The HEPA-ROUNDS mnemonic provides a structured approach that incorporates critical concepts in terms of prevention, management, and prognostication of the most common complications frequently encountered in patients with advanced chronic liver disease. In addition, implementing the HEPA-ROUNDS mnemonic can facilitate education for trainees and staff caring for patients with advanced chronic liver disease.

Abstract
Living donor liver transplantation was first developed to mitigate the limited access to deceased donor organs in Asia in the 1990s. This alternative liver transplantation option has become an established and widely practiced transplantation method for adult patients suffering from end-stage liver disease. It has successfully addressed the shortage of deceased donors. The Society for the Advancement of Transplant Anesthesia and the Korean Society of Transplant Anesthesia jointly reviewed published studies on the perioperative management of live donor liver transplant recipients. The review aims to offer transplant anesthesiologists and critical care physicians a comprehensive overview of the perioperative management of adult live liver transplantation recipients. We feature the status, outcomes, surgical procedure, portal venous decompression, anesthetic management, prevention of acute kidney injury, avoidance of blood transfusion, monitoring and therapeutic strategies of hemodynamic derangements, and Enhanced Recovery After Surgery protocols for liver transplant recipients.

Abstract
Congenital hyperinsulinism (CHI) is a rare disease characterized by an unregulated insulin release, leading to hypoglycaemia. It is the most frequent cause of persistent and severe hypoglycaemia in the neonatal period and early childhood. Mutations in 16 different key genes (ABCC8, KCNJ11, GLUD1, GCK, HADH, SLC16A1, UCP2, HNF4A, HNF1A, HK1, KCNQ1, CACNA1D, FOXA2, EIF2S3, PGM1 and PMM2) that are involved in regulating the insulin secretion from pancreatic β-cells have been described to be responsible for the underlying molecular mechanisms of CHI. CHI can also be associated with specific syndromes and can be secondary to intrauterine growth restriction (IUGR), maternal diabetes, birth asphyxia, etc. It is important to diagnose and promptly initiate appropriate management as untreated hypoglycaemia can be associated with significant neurodisability. CHI can be histopathologically classified into diffuse, focal and atypical forms. Advances in molecular genetics, imaging techniques (18F-fluoro-l-dihydroxyphenylalanine positron emission tomography/computed tomography scanning), novel medical therapies and surgical advances (laparoscopic pancreatectomy) have changed the management and improved the outcome of patients with CHI. This review article provides an overview of the background, clinical presentation, diagnosis, molecular genetics and therapy for children with different forms of CHI.

Abstract
Acromegaly is a chronic systemic disease characterized by facial and peripheral changes caused by soft tissue overgrowth and is associated with multiple comorbidities. Despite available surgical and medical therapies, suitable treatments for acromegaly are still lacking. Efficient drug development requires an understanding of the exposure-response (E-R) relationship based on nonclinical and early clinical studies. We aimed to establish a platform to facilitate the development of novel drugs to treat acromegaly. We evaluated the E-R relationship of the growth hormone (GH)-inhibitory effect of the somatostatin analog octreotide under growth hormone-releasing hormone + arginine stimulation in healthy participants and compared the results with historical data for patients with acromegaly. This randomized five-way crossover study included two placebo and three active-treatment periods with different doses of octreotide acetate. GH secretion in the two placebo periods was comparable, which confirmed the reproducibility of the response with no carryover effect. GH secretion was inhibited by low-, medium-, and high-dose octreotide acetate in a dose-dependent manner. We also examined the E-R relationship in monkeys as a preclinical drug evaluation study and in rats as a more convenient and simple system for screening candidate drugs. The E-R relationships and EC50 values were similar among animals, healthy participants, and patients with acromegaly, which suggests that GH stimulation studies in early research and development allowed simulation of the drug response in patients with acromegaly. SIGNIFICANCE STATEMENT: This study demonstrated similar exposure-response relationships in terms of the growth hormone-inhibitory effect of octreotide after growth hormone-releasing hormone stimulation among healthy participants, monkeys, and rats. The research methods and analyses utilized in this study will be useful for simulating the dosages and therapeutic effects of drugs for acromegaly and will facilitate the research and development of novel therapeutic agents with similar modes of action.

Abstract
Background Vasoactive drugs can reduce portal venous pressure and control variceal bleeding. However, few studies have explored the hemodynamic effects of terlipressin and high-dose octreotide in such patients. Our purpose was to evaluate the hemodynamic changes and safety of using terlipressin and high-dose octreotide in patients with decompensated liver cirrhosis. Methods A multi-center randomized controlled trial was conducted. Cirrhotic patients with a history of variceal bleeding were included. Terlipressin or high-dose octreotide was administered during the procedure of measuring hepatic venous pressure gradient (HVPG). Hemodynamic parameters and symptoms were recorded. Results A total of 88 patients were included. HVPG was significantly reduced at 10, 20, and 30 min after drug administration in the terlipressin group (16.3±6.4 vs. 14.7±5.9, 14.0±6.1, and 13.8±6.1, respectively, P<0.001) and the high-dose octreotide group (17.4±6.6 vs. 15.1±5.8, 15.3±6.2, and 16.1±6.0, respectively P<0.01). Decreased heart rate and increased mean arterial pressure were more often observed in the terlipressin group. The overall response rates were not significantly different between the groups (52.8% vs. 44.8%, P=0.524). The terlipressin group had significantly higher response rates at 30 min compared to the high-dose octreotide group in those with alcoholic liver cirrhosis [6/6 (100%) vs. 0/4 (0%), P=0.005]. The incidence of adverse drug events was rare and similar in the two groups. Conclusions Both terlipressin and high-dose octreotide were effective and safe for reducing HVPG. The pharmacodynamic effect of terlipressin persisted longer. The terlipressin group had higher response rates in those with alcoholic cirrhosis (trial number: NCT02119884).

Abstract
BACKGROUND Approximately 40% to 95% of people with cirrhosis have oesophageal varices. About 15% to 20% of oesophageal varices bleed in about one to three years. There are several different treatments to prevent bleeding, including: beta-blockers, endoscopic sclerotherapy, and variceal band ligation. However, there is uncertainty surrounding their individual and relative benefits and harms. OBJECTIVES To compare the benefits and harms of different treatments for prevention of first variceal bleeding from oesophageal varices in adults with liver cirrhosis through a network meta-analysis and to generate rankings of the different treatments for prevention of first variceal bleeding from oesophageal varices according to their safety and efficacy. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, Science Citation Index Expanded, World Health Organization International Clinical Trials Registry Platform, and trials registers to December 2019 to identify randomised clinical trials in people with cirrhosis and oesophageal varices with no history of bleeding. SELECTION CRITERIA We included only randomised clinical trials (irrespective of language, blinding, or status) in adults with cirrhosis and oesophageal varices with no history of bleeding. We excluded randomised clinical trials in which participants had previous bleeding from oesophageal varices and those who had previously undergone liver transplantation or previously received prophylactic treatment for oesophageal varices. DATA COLLECTION AND ANALYSIS We performed a network meta-analysis with OpenBUGS using Bayesian methods and calculated the differences in treatments using hazard ratios (HR), odds ratios (OR), and rate ratios with 95% credible intervals (CrI) based on an available-case analysis, according to National Institute for Health and Care Excellence Decision Support Unit guidance. We performed the direct comparisons from randomised clinical trials using the same codes and the same technical details. MAIN RESULTS We included 66 randomised clinical trials (6653 participants) in the review. Sixty trials (6212 participants) provided data for one or more comparisons in the review. The trials that provided the information included people with cirrhosis due to varied aetiologies and those at high risk of bleeding from oesophageal varices. The follow-up in the trials that reported outcomes ranged from 6 months to 60 months. All but one of the trials were at high risk of bias. The interventions compared included beta-blockers, no active intervention, variceal band ligation, sclerotherapy, beta-blockers plus variceal band ligation, beta-blockers plus nitrates, nitrates, beta-blockers plus sclerotherapy, and portocaval shunt. Overall, 21.2% of participants who received non-selective beta-blockers ('beta-blockers') - the reference treatment (chosen because this was the most common treatment compared in the trials) - died during 8-month to 60-month follow-up. Based on low-certainty evidence, beta-blockers, variceal band ligation, sclerotherapy, and beta-blockers plus nitrates all had lower mortality versus no active intervention (beta-blockers: HR 0.49, 95% CrI 0.36 to 0.67; direct comparison HR: 0.59, 95% CrI 0.42 to 0.83; 10 trials, 1200 participants; variceal band ligation: HR 0.51, 95% CrI 0.35 to 0.74; direct comparison HR 0.49, 95% CrI 0.12 to 2.14; 3 trials, 355 participants; sclerotherapy: HR 0.66, 95% CrI 0.51 to 0.85; direct comparison HR 0.61, 95% CrI 0.41 to 0.90; 18 trials, 1666 participants; beta-blockers plus nitrates: HR 0.41, 95% CrI 0.20 to 0.85; no direct comparison). No trials reported health-related quality of life. Based on low-certainty evidence, variceal band ligation had a higher number of serious adverse events (number of events) than beta-blockers (rate ratio 10.49, 95% CrI 2.83 to 60.64; 1 trial, 168 participants). Based on low-certainty evidence, beta-blockers plus nitrates had a higher number of 'any adverse events (number of participants)' than beta-blockers alone (OR 3.41, 95% CrI 1.11 to 11.28; 1 trial, 57 participants). Based on low-certainty evidence, adverse events (number of events) were higher in sclerotherapy than in beta-blockers (rate ratio 2.49, 95% CrI 1.53 to 4.22; direct comparison rate ratio 2.47, 95% CrI 1.27 to 5.06; 2 trials, 90 participants), and in beta-blockers plus variceal band ligation than in beta-blockers (direct comparison rate ratio 1.72, 95% CrI 1.08 to 2.76; 1 trial, 140 participants). Based on low-certainty evidence, any variceal bleed was lower in beta-blockers plus variceal band ligation than in beta-blockers (direct comparison HR 0.21, 95% CrI 0.04 to 0.71; 1 trial, 173 participants). Based on low-certainty evidence, any variceal bleed was higher in nitrates than beta-blockers (direct comparison HR 6.40, 95% CrI 1.58 to 47.42; 1 trial, 52 participants). The evidence indicates considerable uncertainty about the effect of the interventions in the remaining comparisons. AUTHORS' CONCLUSIONS Based on low-certainty evidence, beta-blockers, variceal band ligation, sclerotherapy, and beta-blockers plus nitrates may decrease mortality compared to no intervention in people with high-risk oesophageal varices in people with cirrhosis and no previous history of bleeding. Based on low-certainty evidence, variceal band ligation may result in a higher number of serious adverse events than beta-blockers. The evidence indicates considerable uncertainty about the effect of beta-blockers versus variceal band ligation on variceal bleeding. The evidence also indicates considerable uncertainty about the effect of the interventions in most of the remaining comparisons.

Abstract
BACKGROUND Approximately 40% to 95% of people with cirrhosis have oesophageal varices. About 15% to 20% of oesophageal varices bleed in about one to three years of diagnosis. Several different treatments are available, which include endoscopic sclerotherapy, variceal band ligation, beta-blockers, transjugular intrahepatic portosystemic shunt (TIPS), and surgical portocaval shunts, among others. However, there is uncertainty surrounding their individual and relative benefits and harms. OBJECTIVES To compare the benefits and harms of different initial treatments for secondary prevention of variceal bleeding in adults with previous oesophageal variceal bleeding due to decompensated liver cirrhosis through a network meta-analysis and to generate rankings of the different treatments for secondary prevention according to their safety and efficacy. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, Science Citation Index Expanded, World Health Organization International Clinical Trials Registry Platform, and trials registers until December 2019 to identify randomised clinical trials in people with cirrhosis and a previous history of bleeding from oesophageal varices. SELECTION CRITERIA We included only randomised clinical trials (irrespective of language, blinding, or status) in adults with cirrhosis and previous history of bleeding from oesophageal varices. We excluded randomised clinical trials in which participants had no previous history of bleeding from oesophageal varices, previous history of bleeding only from gastric varices, those who failed previous treatment (refractory bleeding), those who had acute bleeding at the time of treatment, and those who had previously undergone liver transplantation. DATA COLLECTION AND ANALYSIS We performed a network meta-analysis with OpenBUGS using Bayesian methods and calculated the differences in treatments using hazard ratios (HR), odds ratios (OR) and rate ratios with 95% credible intervals (CrI) based on an available-case analysis, according to National Institute of Health and Care Excellence Decision Support Unit guidance. MAIN RESULTS We included a total of 48 randomised clinical trials (3526 participants) in the review. Forty-six trials (3442 participants) were included in one or more comparisons. The trials that provided the information included people with cirrhosis due to varied aetiologies. The follow-up ranged from two months to 61 months. All the trials were at high risk of bias. A total of 12 interventions were compared in these trials (sclerotherapy, beta-blockers, variceal band ligation, beta-blockers plus sclerotherapy, no active intervention, TIPS (transjugular intrahepatic portosystemic shunt), beta-blockers plus nitrates, portocaval shunt, sclerotherapy plus variceal band ligation, beta-blockers plus nitrates plus variceal band ligation, beta-blockers plus variceal band ligation, sclerotherapy plus nitrates). Overall, 22.5% of the trial participants who received the reference treatment (chosen because this was the commonest treatment compared in the trials) of sclerotherapy died during the follow-up period ranging from two months to 61 months. There was considerable uncertainty in the effects of interventions on mortality. Accordingly, none of the interventions showed superiority over another. None of the trials reported health-related quality of life. Based on low-certainty evidence, variceal band ligation may result in fewer serious adverse events (number of people) than sclerotherapy (OR 0.19; 95% CrI 0.06 to 0.54; 1 trial; 100 participants). Based on low or very low-certainty evidence, the adverse events (number of participants) and adverse events (number of events) may be different across many comparisons; however, these differences are due to very small trials at high risk of bias showing large differences in some comparisons leading to many differences despite absence of direct evidence. Based on low-certainty evidence, TIPS may result in large decrease in symptomatic rebleed than variceal band ligation (HR 0.12; 95% CrI 0.03 to 0.41; 1 trial; 58 participants). Based on moderate-certainty evidence, any variceal rebleed was probably lower in sclerotherapy than in no active intervention (HR 0.62; 95% CrI 0.35 to 0.99, direct comparison HR 0.66; 95% CrI 0.11 to 3.13; 3 trials; 296 participants), beta-blockers plus sclerotherapy than sclerotherapy alone (HR 0.60; 95% CrI 0.37 to 0.95; direct comparison HR 0.50; 95% CrI 0.07 to 2.96; 4 trials; 231 participants); TIPS than sclerotherapy (HR 0.18; 95% CrI 0.08 to 0.38; direct comparison HR 0.22; 95% CrI 0.01 to 7.51; 2 trials; 109 participants), and in portocaval shunt than sclerotherapy (HR 0.21; 95% CrI 0.05 to 0.77; no direct comparison) groups. Based on low-certainty evidence, beta-blockers alone and TIPS might result in more, other compensation, events than sclerotherapy (rate ratio 2.37; 95% CrI 1.35 to 4.67; 1 trial; 65 participants and rate ratio 2.30; 95% CrI 1.20 to 4.65; 2 trials; 109 participants; low-certainty evidence). The evidence indicates considerable uncertainty about the effect of the interventions including those related to beta-blockers plus variceal band ligation in the remaining comparisons. AUTHORS' CONCLUSIONS The evidence indicates considerable uncertainty about the effect of the interventions on mortality. Variceal band ligation might result in fewer serious adverse events than sclerotherapy. TIPS might result in a large decrease in symptomatic rebleed than variceal band ligation. Sclerotherapy probably results in fewer 'any' variceal rebleeding than no active intervention. Beta-blockers plus sclerotherapy and TIPS probably result in fewer 'any' variceal rebleeding than sclerotherapy. Beta-blockers alone and TIPS might result in more other compensation events than sclerotherapy. The evidence indicates considerable uncertainty about the effect of the interventions in the remaining comparisons. Accordingly, high-quality randomised comparative clinical trials are needed.

Abstract
AIMS The efficacy of somatostatin in altering splanchnic hemodynamics in cirrhotic portal hypertension is still controversial. We aimed to establish the dynamic effect of somatostatin on portal pressure in cirrhotic patients and compared its effect with Partial Splenic Embolization (PSE). METHODS Eighteen patients with cirrhotic portal hypertension were prospectively recruited. The wedged hepatic venous pressure (WHVP) and free hepatic venous pressure (FHVP) were repeatedly measured at baseline, 1-, 5-, 10- and 20-min after initiating somatostatin infusion. After somatostatin infusion cessation and washout, WHVP and FHVP were measured before and after PSE. The change in all the variables between time points was analyzed. RESULTS Decreased hepatic venous pressure gradient (HVPG) 5-min after initiation of infusion was identified compared with baseline level (19.6%; p-value: .042), which was achieved through elevated FHVP (37.5%; p-value: 9.26e - 04). There was no significant decrease in WHVP at any time point during somatostatin infusion. The HVPG (17.4%; p-value: 1.27e - 04) and WHVP (10.4%; p-value: 3.00e - 03) post-PSE significantly decreased compared to the washout level. No significant distribution differences in the number of patients with HVPG decrease by a percentage relative to the baseline level were identified between the 5-min time point and post-PSE. CONCLUSION Our study indicates that somatostatin administration does not decrease WHVP within 20 min at clinically recommended doses. While somatostatin did decrease HVPG, this effect was achieved through increased FHVP, providing a possible explanation for its unclear efficacy. In contrast, PSE decreases both the WHVP and the HVPG.

Abstract
Portal hypertension and bleeding from gastroesophageal varices is the major cause of morbidity and mortality in patients with cirrhosis. Portal hypertension is initiated by increased intrahepatic vascular resistance and a hyperdynamic circulatory state. The latter is characterized by a high cardiac output, increased total blood volume and splanchnic vasodilatation, resulting in increased mesenteric blood flow. Pharmacological manipulation of cirrhotic portal hypertension targets both the splanchnic and hepatic vascular beds. Drugs such as angiotensin converting enzyme inhibitors and angiotensin II type receptor 1 blockers, which target the components of the classical renin angiotensin system (RAS), are expected to reduce intrahepatic vascular tone by reducing extracellular matrix deposition and vasoactivity of contractile cells and thereby improve portal hypertension. However, these drugs have been shown to produce significant off-target effects such as systemic hypotension and renal failure. Therefore, the current pharmacological mainstay in clinical practice to prevent variceal bleeding and improving patient survival by reducing portal pressure is non-selective -blockers (NSBBs). These NSBBs work by reducing cardiac output and splanchnic vasodilatation but most patients do not achieve an optimal therapeutic response and a significant proportion of patients are unable to tolerate these drugs. Although statins, used alone or in combination with NSBBs, have been shown to improve portal pressure and overall mortality in cirrhotic patients, further randomized clinical trials are warranted involving larger patient populations with clear clinical end points. On the other hand, recent findings from studies that have investigated the potential use of the blockers of the components of the alternate RAS provided compelling evidence that could lead to the development of drugs targeting the splanchnic vascular bed to inhibit splanchnic vasodilatation in portal hypertension. This review outlines the mechanisms related to the pathogenesis of portal hypertension and attempts to provide an update on currently available therapeutic approaches in the management of portal hypertension with special emphasis on how the alternate RAS could be manipulated in our search for development of safe, specific and effective novel therapies to treat portal hypertension in cirrhosis.

Abstract
PURPOSE OF REVIEW To summarize the use of gastrointestinal peptides in the management of portal hypertension. RECENT FINDINGS Vasoactive peptides are commonly used in the management of acute variceal hemorrhage and hepatorenal syndrome, which are portal hypertensive complications of cirrhosis. The main vasoactive peptides that are used are somatostatin and its long-acting analogue octreotide, and vasopressin and its analogue terlipressin. Early initiation of vasoactive peptides in the management of acute variceal hemorrhage and hepatorenal syndrome is associated with improved outcomes. Octreotide is the available vasoactive peptide in the Unites States. Recent developments and ongoing clinical trials may improve our understanding of hepatorenal syndrome and influence the use of vasoactive peptides, particularly terlipressin. SUMMARY Here, we review the literature on the use of vasoactive peptides in the management of acute variceal hemorrhage and hepatorenal syndrome.

Abstract
BACKGROUND Vasoactive drugs and endoscopic therapy have been widely used in the management of acute variceal bleeding of cirrhosis patients. The current standard regimen of vasoactive drugs is in combination with endoscopic therapy and continues for up to 5 days; however, the necessity of vasoactive drugs after endoscopic hemostasis was still controversial. Therefore, we conducted a systematic review and meta-analysis to evaluate the efficacy and optimal duration of adjuvant vasoactive drugs after hemorrhage control by endoscopic therapy. METHODS A search was conducted of PubMed, EMBASE, and Cochrane Library databases until June, 2018. Lan DeMets sequential monitoring boundary was constructed to assess the reliability and conclusiveness of our major results. RESULTS Seven studies (639 patients) and 4 studies (435 patients) were included in the analyses to evaluate the efficacy and optimal duration of adjuvant vasoactive drugs therapy, respectively. Our analyses showed that adjuvant vasoactive drugs facilitated endoscopic hemostasis and reduced very early re-bleeding rate both in sclerotherapy (risk ratio [RR] 0.51, 95% confidence interval [CI] 0.34-0.78, P = .23, I = 31%) and band ligation (RR 0.48, 95% CI 0.27-0.83, P = .07, I = 62%). However, the 3 to 5-day therapy duration was not superior to a shorter course in very early re-bleeding rate and mortality rate in 42 days (RR 1.77, 95% CI 0.64-4.89, P = .70, I = 0%; RR 0.95, 95% CI 0.43-2.13, P = .81, I = 0%, respectively). CONCLUSION Additional 5-day vasoactive drug after endoscopic hemostasis may significantly ameliorate very early re-bleeding rate, However, the 3 to 5 days' adjuvant regimen was not superior to a shorter course.

Abstract
Pancreatic β-cells are finely tuned to secrete insulin so that plasma glucose levels are maintained within a narrow physiological range (3.5-5.5 mmol/L). Hyperinsulinaemic hypoglycaemia (HH) is the inappropriate secretion of insulin in the presence of low plasma glucose levels and leads to severe and persistent hypoglycaemia in neonates and children. Mutations in 12 different key genes (ABCC8, KCNJ11, GLUD1, GCK, HADH, SLC16A1, UCP2, HNF4A, HNF1A, HK1, PGM1 and PMM2) that are involved in the regulation of insulin secretion from pancreatic β-cells have been described to be responsible for the underlying molecular mechanisms leading to congenital HH. In HH due to the inhibitory effect of insulin on lipolysis and ketogenesis there is suppressed ketone body formation in the presence of hypoglycaemia thus leading to increased risk of hypoglycaemic brain injury. Therefore, a prompt diagnosis and immediate management of HH is essential to avoid hypoglycaemic brain injury and long-term neurological complications in children. Advances in molecular genetics, imaging techniques (18F-DOPA positron emission tomography/computed tomography scanning), medical therapy and surgical advances (laparoscopic and open pancreatectomy) have changed the management and improved the outcome of patients with HH. This review article provides an overview to the background, clinical presentation, diagnosis, molecular genetics and therapy in children with different forms of HH.

Abstract
Glucose homeostasis requires appropriate and synchronous coordination of metabolic events and hormonal activities to keep plasma glucose concentrations in a narrow range of 3.5–5.5 mmol/L. Insulin, the only glucose lowering hormone secreted from pancreatic β-cells, plays the key role in glucose homeostasis. Insulin release from pancreatic β-cells is mainly regulated by intracellular ATP-generating metabolic pathways. Hyperinsulinaemic hypoglycaemia (HH), the most common cause of severe and persistent hypoglycaemia in neonates and children, is the inappropriate secretion of insulin which occurs despite low plasma glucose levels leading to severe and persistent hypoketotic hypoglycaemia. Mutations in 12 different key genes (ABCC8, KCNJ11, GLUD1, GCK, HADH, SLC16A1, UCP2, HNF4A, HNF1A, HK1, PGM1 and PMM2) constitute the underlying molecular mechanisms of congenital HH. Since insulin supressess ketogenesis, the alternative energy source to the brain, a prompt diagnosis and immediate management of HH is essential to avoid irreversible hypoglycaemic brain damage in children. Advances in molecular genetics, imaging methods (18F–DOPA PET-CT), medical therapy and surgical approach (laparoscopic and open pancreatectomy) have changed the management and improved the outcome of patients with HH. This up to date review article provides a background to the diagnosis, molecular genetics, recent advances and therapeutic options in the field of HH in children.

Abstract
Acute variceal bleeding should be suspected in all patients with cirrhosis presenting with upper gastrointestinal bleeding. Vasoactive drugs and prophylactic antibiotics must be started as soon as possible, even before performing the diagnostic endoscopy. Once the patient is hemodynamically stable, upper gastrointestinal endoscopy should be performed in order to confirm the diagnosis and provide endoscopic therapy (preferably banding ligation). After this initial approach, the most appropriate therapy to prevent both early and late rebleeding must be instituted following a risk stratification strategy. The present chapter will focus on the initial management of patients with acute variceal bleeding, including general management and hemostatic therapies, as well as the available treatments in case of failure to control bleeding or development of rebleeding.

Abstract
Objective: To estimate the effect of portal pressure lowering drug ‘octreotide’, by observing the Doppler waveform before and after the administration of intravenous bolus of octreotide and thus to assess indirectly its efficacy to lower the portal pressure. Methods: This quassi experimental study was carried out in Medical Department in collaboration with Radiology Department of Jinnah Postgraduate Medical Center Karachi Pakistan from September 10, 2015 to February 5, 2016. Cases were selected from patients admitted in Medical Wards and those attending Medical OPD. Diagnosis of cirrhosis was confirmed by Clinical Examination and Lab & Imaging investigation in Medical Department. Doppler waveform study was done by experienced radiologist in Radiology Department before and after administration of octreotide. Doppler signals were obtained from the right hepatic vein. Waveform tracings were recorded for five seconds and categorized as ‘monophasic’, ‘biphasic’ and ‘triphasic’. Waveform changes from one waveform to other were noted and analyzed. Results: Significant change i.e. from ‘monophasic’ to ‘biphasic’ or ‘biphasic’ to ‘triphasic’ was seen in 56% cases while ‘monophasic’ to ‘triphasic’ was seen in 20% cases. No change was seen in 24% cases. Improvement in waveform reflects lowering of portal vein pressure. Conclusion: Non invasive Hepatic vein Doppler waveform study showed improvement in Doppler waveform after administration of octreotide in 76% cases. Doppler waveform study has the potential of becoming non invasive ‘follow up tool’ of choice for assessing portal pressure in patients having variceal bleed due to portal hypertension.

Abstract
Survival rates of critically ill patients with liver disease has sharply increased in recent years due to several improvements in the management of decompensated cirrhosis and acute liver failure. This is ascribed to the incorporation of evidence-based strategies from clinical trials aiming to reduce mortality. In order to discuss the cutting-edge evidence regarding critical care of patients with liver disease, a joint single topic conference was recently sponsored by the Brazilian Society of Hepatology in cooperation with the Brazilian Society of Intensive Care Medicine and the Brazilian Association for Organ Transplantation. This paper summarizes the proceedings of the aforementioned meeting and it is intended to guide intensive care physicians, gastroenterologists and hepatologists in the care management of patients with liver disease.

Abstract
INTRODUCTION Counteracting splanchnic vasodilatation and increased portal-collateral blood flow has been the mainstay for the treatment of portal hypertension (PH) over the past three decades. However, there is still large room for improvement in the treatment of PH. AREAS COVERED The basic mechanism leading to portal hypertension is the increased hepatic vascular resistance to portal blood flow caused by liver structural abnormalities inherent to cirrhosis and increased hepatic vascular tone. Molecules modulating microvascular dysfunction which have undergone preclinical and clinical trials are summarized, potential drug development issues are addressed, and situations relevant to design of clinical trials are considered. EXPERT OPINION Experimental and clinical evidence indicates that molecules modulating liver microvascular dysfunction may allow for 30-40% reduction in portal pressure. Several agents could be utilized in the earlier stages of cirrhosis (antifibrotics, antiangiogenics, etiological therapies) may allow reduction of fibrosis and halt progression of PH. This 'nip at the bud' policy, by combining therapies with existing agents used in advanced phase of cirrhosis and novel agents which could be used in early phase of cirrhotic spectrum, which are likely to hit the market soon would be the future strategy for PH therapy.

Abstract
OBJECTIVE Esophageal variceal bleeding is the most dangerous complication in patients with liver cirrhosis, and it is accompanied by high mortality. Their treatment can be complex, and requires a multidisciplinary approach. This review examines current approaches to the management of patients with liver cirrhosis who have acute esophageal variceal bleeding. METHODS PubMed, Google Scholar, and Cochrane Systematic Reviews were searched for articles published between 1987 and 2015. Relevant articles were identified using the following terms: 'esophageal variceal bleeding', 'portal hypertension' and 'complications of liver cirrhosis'. The reference lists of articles identified were also searched for other relevant publications. Inclusion criteria were restricted to the management of patients with liver cirrhosis who have acute esophageal variceal bleeding. RESULTS It is currently recommended to combine vasoactive drugs (preferable somatostatin or terlipressin) and endoscopic therapies (endoscopic band ligation as first choice, sclerotherapy if endoscopic band ligation not feasible) for the initial treatment of acute variceal bleeding. Antibiotic prophylaxis must be regarded as an integral part of the treatment. The use of a Sengstaken-Blakemore tube is appropriate only in cases of refractory bleeding if the above methods cannot be used. An alternative to balloon tamponade may be the installation of self-expandable metal stents. The transjugular intrahepatic portosystemic shunt is an extremely useful technique for the treatment of acute bleeding from esophageal varices. Although most current clinical guidelines classify it as second-line therapy, the Baveno VI workshop recommends early transjugular intrahepatic portosystemic shunt with expanded polytetrafluoroethylene-covered stents within 72 h (ideally <24 h) in patients with esophageal variceal bleeding at high risk of treatment failure (e.g. Child-Turcotte-Pugh class C < 14 points or Child-Turcotte-Pugh class B with active bleeding) after initial pharmacological and endoscopic therapy. Urgent surgical intervention is rarely performed and can be considered only in case of failure of conservative and/or endoscopic therapy and being unable to use a transjugular intrahepatic portosystemic shunt. Among surgical operations described in the literature are a variety of portocaval anastomosis and azygoportal disconnection procedures. CONCLUSIONS To improve the results of treatment for patients with liver cirrhosis who develop acute esophageal variceal bleeding, it is important to stratify patients into risk groups, which will allow one to tailor therapeutic approaches to the expected results.

Abstract
BACKGROUND Operations and anesthesia in carcinoid patients can provoke carcinoid crises, which can have serious sequelae, including death. Prophylactic octreotide is recommended to prevent crises. Recommended prophylaxis regimens vary from octreotide long-acting repeatable to preoperative bolus to continuous octreotide infusion; however, efficacy data are lacking. We have shown previously that crises correlated with major complications and that octreotide long-acting repeatable and preoperative bolus failed to prevent crises. This study examines the impact of continuous octreotide infusion. METHODS A total of 127 patients (71% with liver metastases, 74% with carcinoid syndrome) who underwent 150 operations with continuous octreotide infusions were enrolled in this prospective case series. Our main outcome measures were the occurrence of intraoperative carcinoid crises and post-operative complications. RESULTS Crises occurred at a rate of 30% as compared with 24% in our previous series, which examined the impact of preoperative octreotide bolus. Crises were significantly associated with the presence of hepatic metastases (P = .02) or history of carcinoid syndrome (P = .006), although neither was required for crises. Prompt vasopressor treatment shortened the mean duration of hypotension to 8.7 minutes, compared with 19 minutes in our prior series. Crises no longer correlated with major complications (P = .481) unless instability persisted for greater than 10 minutes (P = .011). CONCLUSION Octreotide infusions do not prevent intraoperative crises. Patients without liver metastases or carcinoid syndrome can have intraoperative crises. Postoperative complications can be decreased by reducing the duration of crises. Further study is needed to determine how best to shorten hemodynamic instability during crises.

Abstract
BACKGROUND Efficacy of endoscopic sclerotherapy in controlling acute variceal bleeding is significantly improved when vasoactive drug is added. Endoscopic variceal ligation (EVL) is superior to sclerotherapy. Whether efficacy of EVL will also improve with addition of somatostatin is not known. We compared EVL plus somatostatin versus EVL plus placebo in control of acute variceal bleeding. METHODS Consecutive cirrhotic patients with acute esophageal variceal bleeding were enrolled. After emergency EVL, patients were randomized to receive either somatostatin (250 mcg/hr) or placebo infusion. Primary endpoint was treatment failure within 5 days. Treatment failure was defined as fresh hematemesis ≥2 h after start of therapy, or a 3 gm drop in Hb, or death. RESULTS 61 patients were enrolled (EVL plus somatostatin group, n = 31 and EVL plus placebo group, n = 30). The baseline characteristics were similar. Within the initial 5-day period, the frequency of treatment failure was similar in both the groups (EVL plus somatostatin group 8/31 [26%] versus EVL plus placebo group 7/30 [23%]; P = 1.000). The mortality was also similar in the two groups (3/31 [10%] vs. 3/30 [10%]; P = 1.000). Baseline HVPG ≥19 mm Hg and active bleeding at index endoscopy were independent predictors of treatment failure. CONCLUSIONS Addition of somatostatin infusion to EVL therapy does not offer any advantage in control of acute variceal bleeding or reducing mortality. The reason for this may be its failure to maintain sustained reduction in portal pressure for five days. Active bleeding at index endoscopy and high baseline HVPG should help choose early alternative treatment options. Trial registered with ClincalTrials.gov vide NCT01267669.

Abstract
Variceal bleeding is the most serious complication of portal hypertension. All cirrhotic patients should be screened endoscopically for varices which are present in about 30% of compensated and 60% of decompensated patients at diagnosis. In patients without varices, endoscopy surveillance should be continued every 2 years. Patients with high-risk varices (moderate or large in size, or with red color signs, or in Child-Pugh C patients) should be treated with a nonselective β-blocker to prevent bleeding (propranolol, nadolol or carvedilol). Endoscopic banding ligation is also effective for the prevention of first bleeding, and it is the first choice in patients with contraindications or intolerance to β-blockers. Acute variceal hemorrhage still has a high mortality rate (around 15%) and requires intensive care management and conservative blood transfusion policy. Treatment is based on the combined use of vasoactive drugs, endoscopic band ligation and prophylactic antibiotics. Failures are best managed by transjugular intrahepatic portosystemic shunt (TIPS). Balloon tamponade or specifically designed covered esophageal stents can be used as a bridge to definitive therapy in unstable patients. Early, preemptive TIPS might be the first choice in patients at high risk of failure (Child-Pugh B with active bleeding or Child-Pugh C up to 13 points). Patients surviving a variceal bleeding are at high risk of rebleeding. A combination of β-blockers and endoscopic band ligation is the most effective therapeutic approach. Preliminary data suggest that the addition of simvastatin increases survival in these patients.

Abstract
Acute variceal hemorrhage (AVH) is a lethal complication of portal hypertension and should be suspected in every patient with liver cirrhosis who presents with upper gastrointestinal bleed. AVH-related mortality has decreased in the last few decades from 40% to 15%-20% due to advances in the general and specific management of variceal hemorrhage. This review summarizes current management of AVH and prevention of recurrent hemorrhage with a focus on pharmacologic therapy.

Abstract
Severe complications of liver cirrhosis are mostly related to portal hypertension. At the base of the pathogenesis of portal hypertension is the increase in hepatic vascular resistance to portal blood flow with subsequent development of hyperdynamic circulation, which, despite of the formation of collateral circulation, promotes progression of portal hypertension. An important role in its pathogenesis is played by the rearrangement of vascular bed and angiogenesis. As a result, strategic directions of the therapy of portal hypertension under liver cirrhosis include selectively decreasing hepatic vascular resistance with preserving or increasing portal blood flow, and correcting hyperdynamic circulation and pathological angiogenesis, while striving to reduce the hepatic venous pressure gradient to less than 12 mmHg or 20% of the baseline. Over the last years, substantial progress in understanding the pathophysiological mechanisms of hemodynamic disorders under liver cirrhosis has resulted in the development of new drugs for their correction. Although the majority of them have so far been investigated only in animal experiments, as well as at the molecular and cellular level, it might be expected that the introduction of the new methods in clinical practice will increase the efficacy of the conservative approach to the prophylaxis and treatment of portal hypertension complications. The purpose of the review is to describe the known methods of portal hypertension pharmacotherapy and discuss the drugs that may affect the basic pathogenetic mechanisms of its development.

Comparison of 2 days versus 5 days of octreotide infusion along with endoscopic therapy in preventing early rebleed from esophageal varices: a randomized clinical study. Eur J Gastroenterol Hepatol 2015; 27:386-92.

Abstract
BACKGROUND Variceal bleeding is a medical emergency with 20% mortality at 6 weeks. The role of vasoactive agents in achieving hemostasis and preventing rebleeding has been well documented. The optimal duration of these agents has not been well established. There are no previous studies yielding the exact duration of octreotide to be administered to prevent rebleed and mortality from esophageal varices. The aim of this study is to evaluate the effect of combination therapy (octreotide and endoscopy), the exact duration of octreotide infusion, its cost-effectiveness, and the outcome in terms of rebleed and mortality. PATIENTS AND METHODS This was a randomized clinical trial including 124 patients with acute variceal bleeding who underwent endoscopic therapy; they were assigned randomly to 2 days (n=62) and 5 days (n=58) of continuous octreotide infusion (50 μg/kg). Early rebleeding (within 42 days of index bleed according to Baveno IV consensus guidelines), transfusion requirement, and mortality were assessed. RESULTS The study had predominantly male patients, average age 47 years. Among the patients in the 2-day group, 3 (4.8%) showed early rebleed versus 5 (8.6%) in the 5-day group, but the difference was not statistically significant (P>0.05). Among the patients in the 2-day group, one patient died after 3 weeks and all the patients in the 5-day group survived till 6 weeks on follow-up, and the survival rates were comparable (P>0.05). The treatment in the 5-day group was 2.5 times costlier than that for the 2-day group as shown by a cost-wise analysis. CONCLUSION Two days of octreotide infusion following endoscopic therapy is sufficient and as efficacious as 5 days of infusion in preventing early rebleed, with reasonably better cost-effectiveness.

Abstract
Acute upper gastrointestinal haemorrhage remains the most common medical emergency managed by gastroenterologists. Causes of upper gastrointestinal bleeding (UGIB) in patients with liver cirrhosis can be grouped into two categories: the first includes lesions that arise by virtue of portal hypertension, namely gastroesophageal varices and portal hypertensive gastropathy; and the second includes lesions seen in the general population (peptic ulcer, erosive gastritis, reflux esophagitis, Mallory-Weiss syndrome, tumors, etc.). Emergency upper gastrointestinal endoscopy is the standard procedure recommended for both diagnosis and treatment of UGIB. The endoscopic treatment of choice for esophageal variceal bleeding is band ligation of varices. Bleeding from gastric varices is treated by injection with cyanoacrylate. Treatment with vasoactive drugs as well as antibiotic treatment is started before or at the same time as endoscopy. Bleeding from portal hypertensive gastropathy is less frequent, usually chronic and treatment options include β-blocker therapy, injection therapy and interventional radiology. The standard of care of UGIB in patients with cirrhosis includes careful resuscitation, preferably in an intensive care setting, medical and endoscopic therapy, early consideration for placement of transjugular intrahepatic portosystemic shunt and, sometimes, surgical therapy or hepatic transplant.

Abstract
UNLABELLED Vasoactive drugs are recommended to be started as soon as possible in suspected variceal bleeding, even before diagnostic endoscopy. However, it is still unclear whether the therapeutic efficacies of the various vasoactive drugs used are comparable. The aim of this prospective, multicenter, randomized, noninferiority trial was to characterize the effects of terlipressin, somatostatin, and octreotide when they are initiated before endoscopic treatment in patients with acute variceal bleeding. Patients with liver cirrhosis and significant upper gastrointestinal bleeding were randomly assigned to receive early administration of terlipressin, somatostatin, or octreotide, followed by endoscopic treatment. Patients with nonvariceal bleeding were excluded after endoscopy. The primary endpoint was 5-day treatment success, defined as control of bleeding without rescue treatment, rebleeding, or mortality, with a noninferiority margin of 0.1. In total, 780 patients with variceal bleeding were enrolled: 261 in the terlipressin group; 259 in the somatostatin group; and 260 in the octreotide group. At the time of initial endoscopy, active bleeding was noted in 43.7%, 44.4%, and 43.5% of these patients, respectively (P=0.748), and treatment success was achieved by day 5 in 86.2%, 83.4%, and 83.8% (P=0.636), with similar rates of control of bleeding without rescue treatment (89.7%, 87.6%, and 88.1%; P=0.752), rebleeding (3.4%, 4.8%, and 4.4%; P=0.739), or mortality (8.0%, 8.9%, and 8.8%; P=0.929). The absolute values of the lower bound of confidence intervals for terlipressin versus somatostatin, terlilpressin versus octreotide, and octreotide versus somatostatin were 0.095, 0.090, and 0.065, respectively. CONCLUSION Hemostatic effects and safety did not differ significantly between terlipressin, somatostatin, and octreotide as adjuvants to endoscopic treatment in patients with acute gastroesophageal variceal bleeding.

Abstract
Acute variceal bleeding (AVB) is the most common cause of upper gastrointestinal hemorrhage in patients with cirrhosis. Advances in the management of AVB have resulted in decreased mortality. To minimize mortality, a multidisciplinary approach addressing airway safety, prompt judicious volume resuscitation, vasoactive and antimicrobial pharmacotherapy, and early endoscopy to obliterate varices is necessary. Placement of a transjugular intrahepatic portosystemic shunt (TIPS) has been used as rescue therapy for patients failing initial attempts at hemostasis. Patients who have a high likelihood of failing initial attempts at hemostasis may benefit from a more aggressive approach using TIPS earlier in their management.

Abstract
OBJECTIVE Pharmacologic therapy (PT) for patients with esophageal variceal hemorrhage (EVH) may improve outcomes. The aim of this article is to assess the current and potential future use of PT in cirrhotic patients with EVH. MATERIAL AND METHODS We validated a 13-question survey about PT and physician preferences for specific therapies in cirrhotics with EVH; 2349 randomly selected Gastroenterology and Hepatology physicians worldwide were surveyed. The survey addressed institutional location, octreotide or terlipressin use and preference, PT prior to endoscopy, and future plans for terlipressin use, if not already instituted. RESULTS Of those surveyed, 337 (14%) email addresses were nonfunctioning. Of the remaining 2012 surveyed, 371 (18%) responses were collected. Nearly two-thirds of physicians preferred to use PT prior to endoscopic intervention (p < 0.001). Nearly 70% of respondents only had octreotide available, while 6% had only terlipressin. Of the 24% having both octreotide and terlipressin available, 55% preferred terlipressin compared to 38% who preferred octreotide (p < 0.001). Of those physicians currently not using terlipressin because of its unavailability, 93% would be willing to use it if it were readily available. CONCLUSIONS Of physicians with both terlipressin and octreotide available for treatment of EVH in cirrhotics, most prefer terlipressin, even if currently unavailable.

Abstract
Gastrointestinal bleeding related to portal hypertension is a serious complication in patients with liver cirrhosis. Most patients bleed from esophageal or gastric varices, but bleeding from ectopic varices or portal hypertensive gastropathy is also possible. The management of acute bleeding has changed over the last years. Patients are managed with a combination of endoscopic and pharmacologic treatment. The endoscopic treatment of choice for esophageal variceal bleeding is variceal band ligation. Bleeding from gastric varices is treated by injection with cyanoacrylate. Treatment with vasoactive drugs as well as antibiotic treatment is started before or at the time point of endoscopy. The first-line treatment for primary prophylaxis of esophageal variceal bleeding is nonselective beta blockers. Pharmacologic therapy is recommended for most patients; band ligation is an alternative in patients with contraindications for or intolerability of beta blockers. Treatment options for secondary prophylaxis include variceal band ligation, beta blockers, a combination of nitrates and beta blockers, and combination of band ligation and pharmacologic treatment. A clear superiority of one treatment over the other has not been shown. Bleeding from portal hypertensive gastropathy or ectopic varices is less common. Treatment options include beta blocker therapy, injection therapy, and interventional radiology.

Abstract
The aim of the Mexican Consensus on Portal Hypertension was to develop documented guidelines to facilitate clinical practice when dealing with key events of the patient presenting with portal hypertension and variceal bleeding. The panel of experts was made up of Mexican gastroenterologists, hepatologists, and endoscopists, all distinguished professionals. The document analyzes themes of interest in the following modules: preprimary and primary prophylaxis, acute variceal hemorrhage, and secondary prophylaxis. The management of variceal bleeding has improved considerably in recent years. Current information indicates that the general management of the cirrhotic patient presenting with variceal bleeding should be carried out by a multidisciplinary team, with such an approach playing a major role in the final outcome. The combination of drug and endoscopic therapies is recommended for initial management; vasoactive drugs should be started as soon as variceal bleeding is suspected and maintained for 5 days. After the patient is stabilized, urgent diagnostic endoscopy should be carried out by a qualified endoscopist, who then performs the corresponding endoscopic variceal treatment. Antibiotic prophylaxis should be regarded as an integral part of treatment, started upon hospital admittance and continued for 5 days. If there is treatment failure, rescue therapies should be carried out immediately, taking into account that interventional radiology therapies are very effective in controlling refractory variceal bleeding. These guidelines have been developed for the purpose of achieving greater clinical efficacy and are based on the best evidence of portal hypertension that is presently available.

Abstract
Variceal hemorrhage is a common and devastating complication of portal hypertension and is a leading cause of death in patients with cirrhosis. The management of gastroesophageal varices has evolved over the last decade resulting in improved mortality and morbidity rates. Regarding the primary prevention of variceal hemorrhaging, nonselective β -blockers should be the first-line therapy in all patients with medium to large varices and in patients with small varices associated with high-risk features such as red wale marks and/or advanced cirrhosis. EVL should be offered in cases of intolerance or side effects to β -blockers, or for patients at high-risk for variceal bleeding who have medium or large varices with red wale marks or advanced liver cirrhosis. In acute bleeding, vasoactive agents should be initiated along with antibiotics followed by EVL or endoscopic sclerotherapy (if EVL is technically difficult) within the first 12 hours of presentation. Where available, terlipressin is the preferred agent because of its safety profile and it represents the only drug with a proven efficacy in improving survival. All patients surviving an episode of bleeding should undergo further prophylaxis to prevent rebleeding with EVL and nonselective β -blockers.

Abstract
BACKGROUND It remains unclear whether a long-acting preparation of octreotide (Sandostatin LAR) can be safely used for portal hypertension in patients with compensated cirrhosis. AIM To determine the safety and efficacy of LAR among patients with Child Pugh Class A or B cirrhosis and small oesophageal varices. METHODS A randomised, double-blind, placebo-controlled study was conducted in 39 patients with cirrhosis and small oesophageal varices. Safety was based on frequency and severity of adverse events. Efficacy was determined by hepatic vein pressure gradient (HVPG) measured at baseline and day 84 following administration of LAR 10 mg (n = 15), 30 mg (n = 10) or saline (n = 14). Fasting and postprandial portal blood flow (PBF), superior mesenteric artery pulsatility index (SMA-PI), glucagon and octreotide levels were measured. An intention-to-treat analysis was performed. RESULTS Four patients in the LAR 30 group (40%) withdrew from the study due to serious adverse events. No patient in the LAR 10 or control group had serious adverse events. There was no statistically significant decrease between HVPG at day 84 and baseline with LAR 30 mg (11.8 ± 2.3 mmHg vs. 14.1 ± 3.2), LAR 10 mg (15.3 ± 4.8 mmHg vs. 15.1 ± 3.8), or saline (13.3 ± 3.8 mmHg vs. 15.1 ± 4.3) (P = 0.26). Neither PBF, SMA-PI nor plasma glucagon levels were significantly decreased from baseline (P = 0.56). CONCLUSIONS The absence of significant haemodynamic benefit, as well as the high frequency of severe adverse events associated with use of LAR, do not support the use of this agent in the treatment of portal hypertension.

Abstract
Drugs, bands, and shunts have all been used in the treatment of varices and variceal hemorrhage and have resulted in improved outcomes. However, the specific use of each of these therapies depends on the setting (primary or secondary prophylaxis, treatment of AVH) and on patient characteristics. The indications for each are summarized in Table 4.

Abstract
Octreotide is a somatostatin analog that constricts the splanchnic circulation, thereby improving orthostatic tolerance. We tested the hypotheses that octreotide improves orthostatic tolerance by 1)increasing cardiac filling (right atrial) pressure via reductions in vascular capacity; 2) by causing an upward (i.e., cranial) shift of the hydrostatic indifferent point; and 3) by increasing arterial pressure via a reduction in total vascular conductance. Studies were carried out in acepromazine-sedated, hexamethonium-treated atrioventricular-blocked conscious dogs lightly restrained in lateral recumbency. Beat-by-beat cardiac output was held constant via computer-controlled ventricular pacing at rest and during 30 s of 30° head-up tilt. Octreotide (1.5 μg/kg iv) raised right atrial pressure by 0.5 mmHg and raised mean arterial pressure by 11 mmHg by reducing total vascular conductance (all P < 0.05). Right atrial pressure fell by a similar amount in response to tilting before and after octreotide, thus there was no difference in location of the hydrostatic indifferent point. These data indicate that octreotide improves orthostatic tolerance by decreasing total vascular conductance and by increasing cardiac filling pressure via a reduction in unstressed vascular volume and not by eliciting a cranial shift of the location of the hydrostatic indifferent point.

Abstract
INTRODUCTION Acute variceal bleeding is a medical emergency and one of the main causes of mortality in patients with cirrhosis. Timely and effective treatment of the acute bleeding episode results in increased survival, and appropriate prophylactic treatment can prevent bleeding or rebleeding from varices. AREAS COVERED We discuss the prevention of development and growth of varices, the primary and secondary prophylaxis of bleeding, the treatment of acute bleeding, and the management of gastric varices. We systematically reviewed studies, without time limits, identified through Medline and searches of reference lists, and provide an overview of the evidence underlying the -treatment options in the management of varices in cirrhosis. EXPERT OPINION The management of variceal hemorrhage relies on nonspecific interventions (e.g., adequate fluid resuscitation, airway protection) and on specific interventions. These are routine prophylactic antibiotics, vasoactive drugs and endoscopic treatment. Procedures such as the placement of a Sengstaken-Blakemore tube or a transjugular intrahepatic portosystemic shunt (TIPS) can be lifesaving. The primary and secondary prophylaxis of bleeding is based on nonselective beta-blockers and endoscopy, even though TIPS or, less frequently, surgery have a role in selected cases.

Abstract
In the last decades, several improvements in the management of variceal bleeding have resulted in a significant decrease in morbidity and mortality of patients with cirrhosis and bleeding varices. Progress in the multidisciplinary approach to these patients 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-to-treat 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, according to evidence-based medicine. After the meeting, all participants met 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 manuscript is the summary of the systematic review that was presented during the meeting, organized in topics, followed by the recommendations of the Brazilian Society of Hepatology.
