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
BACKGROUND Observational studies suggest that hepatorenal syndrome (HRS) patients who receive pharmacological therapy before orthotopic liver transplantation display a post-transplant outcome similar to those without HRS. The aim of this study was to comprehensively compare and rank the pharmacological therapies for HRS. METHODS We reviewed PubMed, Elsevier, Medline, and the Cochrane Central Register of Controlled Trials (CENTRAL) for studies that were published between 1 January 1999 and 24 February 2018. The primary endpoint was reversal of HRS. The secondary endpoints were the changes in serum creatinine (Scr) and serum sodium. We evaluated the different therapeutic strategies using network meta-analysis on the basis of Bayesian methodology. RESULTS The study included 24 articles with 1,419 participants evaluating seven different therapeutic strategies for HRS. The most effective treatments to induce reversal of HRS were terlipressin plus albumin, noradrenaline plus albumin, and terlipressin, which had a surface under the cumulative ranking curve (SUCRA) of 0.086, 0.151, and 0.451, respectively. The top two treatments for decreasing Scr were dopamine plus furosemide plus albumin (rank probability: 0.620) and terlipressin plus albumin (rank probability: 0.570). For increasing serum sodium, the optimal treatment was octreotide plus midodrine plus albumin (rank probability: 0.800), followed by terlipressin plus albumin (rank probability: 0.544). CONCLUSIONS Terlipressin plus albumin and dopamine plus furosemide plus albumin should be prioritized for decreasing Scr in HRS, and octreotide plus midodrine plus albumin was the most effective at increasing serum sodium. Terlipressin plus albumin showed a comprehensive effect in both decreasing Scr and increasing serum sodium.

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
Chylous ascites is infequent after abdominal surgery. We describe the case of a 43-year-old man with portal cavernomatosis who underwent surgery to insert a splenorenal shunt, which was not placed due to the absence of signs of portal hypertension. On postoperative day 20, the patient developed abdominal distension and mild dyspnea and was diagnosed with chylous ascites, which was related to the surgery. The patient was initially treated with diet and diuretics, with no clinical response, and consequently octreotide therapy was started. Four days later, the ascites was almost resolved and an ultrasound scan at 4 months showed its complete disappearance. This article demonstrates the effectiveness of octreotide in the treatment of postsurgical chylous ascites.

Abstract
Terlipressin, a vasopressin agonist, is a commonly used drug with different indications, particularly in patients with end-stage liver disease. As a V(1) receptor agonist, it increases systemic vascular resistance, particularly in the splanchnic area, resulting in a decrease of portal pressure. Besides the approved use for variceal bleeding, terlipressin also has beneficial effects in the treatment of hepatorenal syndrome and norepinephrine-resistant septic shock. In patients with cirrhosis and variceal bleeding, the use of terlipressin reduces the portal vein pressure and decreases the pressure in esophageal varices. This can save lives when skilled endoscopists are not immediately available. Hepatorenal syndrome is associated with vasodilation in the mesenteric circulation with arterial underfilling and consecutive renal vasoconstriction. Restoration of an effective arterial blood volume can be achieved by the combination of terlipressin and volume expansion. In some cases, a success rate of up to 75% is reported. The early use of terlipressin in catecholamine-resistant shock can improve organ perfusion.

Abstract
Portal hypertension is one of the main consequences of cirrhosis. It results from a combination of increased intrahepatic vascular resistance and increased blood flow through the portal venous system. The condition leads to the formation of portosystemic collateral veins. Esophagogastric varices have the greatest clinical impact, with a risk of bleeding as high as 30% within 2 years of medium or large varices developing. Ascites, another important complication of advanced cirrhosis and severe portal hypertension, is sometimes refractory to treatment and is complicated by spontaneous bacterial peritonitis and hepatorenal syndrome. We describe the pathophysiology of portal hypertension and the current management of its complications, with emphasis on the prophylaxis and treatment of variceal bleeding and ascites.

Abstract
Vasoactive drugs are safe and easy to administer, and universal treatment is the first-line approach for all patients with suspected variceal bleeding. There are strong arguments that the combination of vasoactive drugs, started as soon as possible, and endotherapy later on is the best therapeutic option, particularly in cases of ongoing bleeding at the time of endoscopy. The main action of vasoactive drugs is to reduce variceal pressure. This can be achieved by diminishing the variceal blood flow and/or by increasing resistance to variceal blood flow inside the varices. Changes in variceal pressure parallel changes in portal pressure. Drugs for the treatment of variceal bleeding can therefore be assessed by measuring the changes in portal pressure, azygos blood flow and variceal pressure. Vasoactive drugs can be divided into two categories: terlipressin (Glypressin), and somatostatin and its analogues, especially octreotide. Terlipressin significantly reduces portal and variceal pressure and azygos flow, is superior to placebo in the control of variceal haemorrhage and improves mortality. It is beneficial when combined with sclerotherapy. It also has the advantage that it might preserve renal function, one of the most important factors affecting the outcome of cirrhosis. As such, terlipressin is the most potent of the various vasoactive drugs. Somatostatin significantly reduces portal and variceal pressure and azygos flow, is superior to placebo in controlling variceal haemorrhage, and improves the success of sclerotherapy. The effect of octreotide is well established for preventing the increase in portal pressure after a meal (similar to blood in the intestines) though the effect of ocreotide on variceal pressure is controversial.

Abstract
UNLABELLED Octreotide may be a life-saving treatment in the case of an acute carcinoid crisis, but when given as an i.v. bolus in larger doses, it may cause significant effects on the cardiac conduction system. We describe cardiac conduction impairment observed during octreotide administration in a patient undergoing carcinoid tumor surgery. In this patient, i.v. boluses of 100 microg of octreotide resulted in symptomatic bradycardia, Mobitz type II atrioventricular block, and complete heart block. Perioperative physicians especially need to be aware of these potential effects because they may be more likely to occur during surgery because of the larger doses and boluses that are used to treat acute symptoms secondary to tumor manipulation. IMPLICATIONS In some susceptible patients, i.v. bolus administration of octreotide may cause significant bradycardia and cardiac conduction defects. Therefore, when octreotide is administered as a bolus, it may be advisable to give it slowly while monitoring the electrocardiogram.

Abstract
BACKGROUND Long-acting somatostatin analogues have been suggested as an alternative to propranolol for the prevention of variceal rebleeding. AIM To compare the effectiveness of lanreotide SR, a new depot formulation injected once-weekly, and propranolol in reducing circadian portal blood flow (PVF) and meal-stimulated hepatic venous pressure gradient (HVPG) in patients with liver cirrhosis. METHODS Patients were randomized to receive either lanreotide SR intramuscularly (30 mg once weekly, n=12) or propranolol (n=12) orally. Hemodynamic measurements were performed on day 0 and on day 21 after a 3-week period of drug administration, while patients received three standard oral liquid test meals. On each study day 27 PVF measurements were performed over 24 h and eight measurements of HVPG during the first postprandial period. RESULTS Propranolol was more effective than lanreotide SR in reducing baseline HVPG (-21.9 vs. -13.6%, P=0.04) and meal-stimulated HVPG (-16.6 vs. -3.8%, P=0.04). Propranolol reduced circadian PVF significantly by 9.3% (P=0.03) but not lanreotide SR. CONCLUSIONS Long-term treatment with propranolol reduced baseline and postprandial HVPG and circadian PVF, while lanreotide SR did not. The results of our study do not encourage clinical testing of lanreotide SR 30 mg for the prevention of variceal haemorrhage.

Abstract
Chylous ascites is an uncommon entity with variable causes and rarely arises from portal vein thrombosis. This is a case report of chylous ascites caused by idiopathic portal vein thrombosis that was refractory to medical therapy and shunt surgery, which showed an impressive response to treatment with subcutaneous octreotide. We review the literature on chylous ascites with particular reference to the role of somatostatin analogs in the management of this rare condition.

Abstract
BACKGROUND Sclerotherapy is the most widely used method for treatment of acute variceal bleeding. Previous reports have suggested that octreotide infusion is as effective as sclerotherapy. Our aim was to investigate the efficacy and safety of octreotide in comparison with sclerotherapy in controlling variceal bleeding. METHODS Seventy-six cirrhotic patients were randomized to receive either sclerotherapy (n = 37) or octreotide (n = 39) infusion of 50 microg/h intravenously for 48 h after a bolus of 100 microg, followed by subcutaneous injection of 100 microg/8 h for an additional 72 h. RESULTS The two groups were similar in base-line data. A similar initial control of bleeding was obtained in 94.6% for sclerotherapy and 84.6% for octreotide (NS). No difference was observed between sclerotherapy and octreotide in rebleeding (23% versus 33%) and treatment failure (22% versus 36%, respectively). Furthermore, the overall success of treatment was 78% for sclerotherapy and 64% for octreotide. No significant difference in mortality was observed between treatments (eight patients for octreotide and three patients for sclerotherapy, NS). CONCLUSIONS These results show that both treatments present a very high and similar initial and final control of bleeding. However, there is a trend that could be clinically important towards better results in the patients treated with sclerotherapy.

Abstract
The splanchnic pharmacodynamic effects of the drugs used for the treatment of hemorrhagic complications of portal hypertension were poorly clarified until some years ago. The introduction of Doppler ultrasound provided a powerful tool to investigate such hemodynamic effects and brought new insights in this field. The present article reviews the pharmacodynamics of the substances used in the treatment of portal hypertension, with particular regard to the effects assessable by duplex Doppler ultrasonography.

Abstract
The aim of the study was to verify the effects of the administration of an inhibitor of the release of endogenous vasodilators together with a vasoconstrictor agent in patients with hepatorenal syndrome (HRS). This new medical perspective was compared with a traditional medical approach for HRS, such as the infusion of nonpressor doses of dopamine to produce renal vasodilation. Thirteen patients with type 1 HRS were enrolled in the study. Five of them were treated with the oral administration of midodrine and the parenteral administration of octreotide. In addition, the patients received 50 to 100 mL of 20% human albumin solution daily for 20 days. Midodrine and octreotide were dosed to obtain a stable increase of at least 15 mm Hg of mean arterial pressure. Eight patients were treated with the intravenous administration of nonpressor doses of dopamine (2-4 micrograms/kg/min) and the same daily amount of albumin. After 20 days of treatment with midodrine and octreotide, an impressive improvement in renal plasma flow (RPF), glomerular filtration rate, and urinary sodium excretion was observed in patients. This was accompanied by a significant reduction in plasma renin activity, plasma vasopressin, and plasma glucagon. No side effects were observed. Three patients were discharged from the hospital. One of them successfully underwent liver transplantation. One of the two remaining patients is still alive after 472 days with a preserved renal function, and the other died from terminal liver failure after 76 days. One of the two patients who were not discharged from the hospital successfully underwent liver transplantation, and the other died from pneumonia after 29 days. Seven out of eight patients who were treated with dopamine experienced a progressive deterioration in renal function and died during the first 12 days. Only one patient recovered renal function and underwent liver transplantation. In conclusion, the long-term administration of midodrine and octreotide seems to be an effective and safe treatment of type 1 HRS in patients with cirrhosis.

Abstract
OBJECTIVE Octreotide has potentially beneficial effects in patients with cirrhosis. However, the effects of octreotide on central hemodynamics and oxygen use have not been established. The present study was undertaken to evaluate the effect of octreotide on central hemodynamics and oxygen use in patients with viral cirrhosis. METHODS Twenty-five patients with cirrhosis were enrolled in the study. They were randomly assigned to receive either placebo (n = 10) or a continuous infusion of 100 microg/h of octreotide after an initial 100-microg bolus (n = 15). Hemodynamic measurements and oxygenation values were obtained before and 60 min after octreotide or placebo administration. RESULTS Placebo administration did not have any effect on hemodynamic and oxygenation values. In patients who received octreotide, systemic hemodynamic values including cardiac index, mean arterial pressure, and systemic vascular resistance were not affected. The mean pulmonary arterial pressure tended to increase after octreotide administration but was statistically insignificant. There was a significant increase in pulmonary arterial vascular resistance, whereas the pulmonary capillary wedge pressure and right atrial pressure were significantly decreased. Arterial oxygen tension, systemic oxygen uptake, and oxygen extraction ratio were significantly decreased after octreotide administration, whereas oxygen transport as well as arterial and mixed venous oxygen contents remained unchanged. CONCLUSIONS In patients with viral cirrhosis, octreotide administration exerted a significant effect on pulmonary circulation. It also resulted in a decrease in systemic oxygen uptake and oxygen extraction ratio. These results suggested that octreotide may impair tissue oxygenation in patients with viral cirrhosis.

Abstract
OBJECTIVE The flow pattern in hepatic veins depends on cardiac physiology and liver histology. The aim of our study was to determine the dependence of the flow pattern of hepatic and portal veins in relation to histologic features in patients with chronic hepatitis C. SUBJECTS AND METHODS In 135 patients with chronic hepatitis C, the Doppler sonography spectrum of the right hepatic vein was classified as triphasic, biphasic, or monophasic. The flow of the portal vein was characterized according to the undulation (velocity(max,min)). A liver biopsy was performed during sonography, and biopsy specimens were semiquantitatively evaluated on a histologic activity index and a score of the hepatic fat content. Multiple logistic regression analysis was used to identify the histologic features that might contribute to the type of flow pattern. RESULTS The hepatocyte fat content was the only variable associated with an independent effect on the type of flow pattern (monophasic versus triphasic; odds ratio, 16.26; 95% confidence interval, 6.38-41.45; p < .0001). A pronounced undulation in the portal vein was associated with portal inflammation but not with other parameters of the histologic activity index or the intrahepatic fat deposition. CONCLUSION On sonography, the normal flow pattern in the right hepatic vein is triphasic. The monophasic flow pattern in the right hepatic vein is mainly caused by intrahepatic fat deposition and occasionally by inflammatory or fibrotic changes. Conversely, the flow pattern of the portal vein is mainly influenced by portal inflammation.

Abstract
BACKGROUND Intravenous octreotide is an established treatment of oesophageal variceal haemorrhage in the cirrhotic patient. AIM To examine the organ extraction and splanchnic haemodynamic effects of octreotide in cirrhotic patients with portal hypertension. METHODS Thirteen patients with cirrhosis had hepatic venous catheterization performed. Hepatic venous pressure gradient (HVPG), indocyanine green (ICG) clearance and hepatic blood flow (HBF) were determined in the basal state and during 60 min of octreotide infusion by bolus injection (0.75 microg/kg) followed by continuous infusion of 0.75 microg/kg x h. Blood samples were simultaneously drawn from the femoral artery and the hepatic and renal veins. RESULTS The extraction fraction of octreotide in the liver was 0.05 (-0.01 - 0.14) (median (interquartile range)) and in the kidneys 0.16 (-0.06 - 0.35). The extraction fraction ratio (E(liver)/E(kidney)) was 0.69 (-0.20 - 1.06). Hepatic clearance was 47 mL/min (3-88) (n = 11). No correlations were found between liver biochemistry or galactose elimination capacity (GEC; a metabolic measure of liver function) and renal extraction fraction or liver clearance. Octreotide had no effect on HVPG or wedged hepatic venous pressure although free hepatic venous pressure increased during octreotide infusion: 6 mmHg (5-9) vs. 7 mmHg (6-10) (P = 0.02). No effect on HBF was observed while ICG clearance decreased significantly. CONCLUSIONS Octreotide is extracted in cirrhotic patients by both the liver and the kidney, the latter being the most important organ of elimination. Octreotide decreases liver metabolic activity determined by the ICG clearance technique, but no significant effects of octreotide on HVPG or HBF could be demonstrated.
