Abstract
BACKGROUND Approximately 40% to 95% of people with liver cirrhosis have oesophageal varices. About 15% to 20% of oesophageal varices bleed within about one to three years after diagnosis. Several different treatments are available, including, among others, endoscopic sclerotherapy, variceal band ligation, somatostatin analogues, vasopressin analogues, and balloon tamponade. However, there is uncertainty surrounding the individual and relative benefits and harms of these treatments. OBJECTIVES To compare the benefits and harms of different initial treatments for variceal bleeding from oesophageal varices in adults with decompensated liver cirrhosis, through a network meta-analysis; and to generate rankings of the different treatments for acute bleeding oesophageal varices, according to their benefits and harms. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, Science Citation Index Expanded, World Health Organization International Clinical Trials Registry Platform, and trials registers until 17 December 2019, to identify randomised clinical trials (RCTs) in people with cirrhosis and acute bleeding from oesophageal varices. SELECTION CRITERIA We included only RCTs (irrespective of language, blinding, or status) in adults with cirrhosis and acutely bleeding oesophageal varices. We excluded RCTs in which participants had bleeding only from gastric varices, those who failed previous treatment (refractory bleeding), those in whom initial haemostasis was achieved before inclusion into the trial, and those who had previously undergone liver transplantation. DATA COLLECTION AND ANALYSIS We performed a network meta-analysis with OpenBUGS software, using Bayesian methods, and calculated the differences in treatments using 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. We performed also the direct comparisons from RCTs using the same codes and the same technical details. MAIN RESULTS We included a total of 52 RCTs (4580 participants) in the review. Forty-eight trials (4042 participants) were included in one or more comparisons in the review. The trials that provided the information included people with cirrhosis due to varied aetiologies and those with and without a previous history of bleeding. We included outcomes assessed up to six weeks. All trials were at high risk of bias. A total of 19 interventions were compared in the trials (sclerotherapy, somatostatin analogues, vasopressin analogues, sclerotherapy plus somatostatin analogues, variceal band ligation, balloon tamponade, somatostatin analogues plus variceal band ligation, nitrates plus vasopressin analogues, no active intervention, sclerotherapy plus variceal band ligation, balloon tamponade plus sclerotherapy, balloon tamponade plus somatostatin analogues, balloon tamponade plus vasopressin analogues, variceal band ligation plus vasopressin analogues, balloon tamponade plus nitrates plus vasopressin analogues, balloon tamponade plus variceal band ligation, portocaval shunt, sclerotherapy plus transjugular intrahepatic portosystemic shunt (TIPS), and sclerotherapy plus vasopressin analogues). We have reported the effect estimates for the primary and secondary outcomes when there was evidence of differences between the interventions against the reference treatment of sclerotherapy, but reported the other results of the primary and secondary outcomes versus the reference treatment of sclerotherapy without the effect estimates when there was no evidence of differences in order to provide a concise summary of the results. Overall, 15.8% of the trial participants who received the reference treatment of sclerotherapy (chosen because this was the commonest treatment compared in the trials) died during the follow-up periods, which ranged from three days to six weeks. Based on moderate-certainty evidence, somatostatin analogues alone had higher mortality than sclerotherapy (OR 1.57, 95% CrI 1.04 to 2.41; network estimate; direct comparison: 4 trials; 353 participants) and vasopressin analogues alone had higher mortality than sclerotherapy (OR 1.70, 95% CrI 1.13 to 2.62; network estimate; direct comparison: 2 trials; 438 participants). None of the trials reported health-related quality of life. Based on low-certainty evidence, a higher proportion of people receiving balloon tamponade plus sclerotherapy had more serious adverse events than those receiving only sclerotherapy (OR 4.23, 95% CrI 1.22 to 17.80; direct estimate; 1 RCT; 60 participants). Based on moderate-certainty evidence, people receiving vasopressin analogues alone and those receiving variceal band ligation had fewer adverse events than those receiving only sclerotherapy (rate ratio 0.59, 95% CrI 0.35 to 0.96; network estimate; direct comparison: 1 RCT; 219 participants; and rate ratio 0.40, 95% CrI 0.21 to 0.74; network estimate; direct comparison: 1 RCT; 77 participants; respectively). Based on low-certainty evidence, the proportion of people who developed symptomatic rebleed was smaller in people who received sclerotherapy plus somatostatin analogues than those receiving only sclerotherapy (OR 0.21, 95% CrI 0.03 to 0.94; direct estimate; 1 RCT; 105 participants). The evidence suggests considerable uncertainty about the effect of the interventions in the remaining comparisons where sclerotherapy was the control intervention. AUTHORS' CONCLUSIONS Based on moderate-certainty evidence, somatostatin analogues alone and vasopressin analogues alone (with supportive therapy) probably result in increased mortality, compared to endoscopic sclerotherapy. Based on moderate-certainty evidence, vasopressin analogues alone and band ligation alone probably result in fewer adverse events compared to endoscopic sclerotherapy. Based on low-certainty evidence, balloon tamponade plus sclerotherapy may result in large increases in serious adverse events compared to sclerotherapy. Based on low-certainty evidence, sclerotherapy plus somatostatin analogues may result in large decreases in symptomatic rebleed compared to sclerotherapy. In the remaining comparisons, the evidence indicates considerable uncertainty about the effects of the interventions, compared to sclerotherapy.

Abstract
BACKGROUND/AIMS The aim of this study was to investigate the mortality, bleeding control rate, and their associated predictors in patients treated with Sengstaken-Blakemore (SB) tube for uncontrolled variceal hemorrhage associated with hemodynamic instability or failure of endoscopic treatment. METHODS The clinical data of 66 consecutive patients with uncontrolled variceal hemorrhage treated with SB tube at Gyeongsang National University Hospital from October 2010 to October 2015 were retrospectively analyzed. RESULTS The overall success rate of initial hemostasis with SB tube was 75.8%, and the independent factors associated with hemostasis were non-intubated state before SB tube (odds ratio, 8.50; p = 0.007) and Child-Pugh score < 11 (odds ratio, 15.65; p = 0.022). Rebleeding rate after successful initial hemostasis with SB tube was 22.0%, and esophageal rupture occurred in 6.1%. Mortality within 30 days was 42.4%, and the related independent factors with mortality were failure of initial hemostasis with SB tube (hazard ratio, 6.24; p < 0.001) and endotracheal intubation before SB tube (hazard ratio, 2.81; p = 0.018). CONCLUSIONS Since the era of endoscopic band ligation, SB tube might be a beneficial option as a temporary salvage treatment for uncontrolled variceal hemorrhage. However, rescue therapy had a high incidence of fatal complication and rebleeding.

Abstract
BACKGROUND The Danish contribution to evaluation and treatment of bleeding oesophageal varices. METHODS Danish papers dealing with portal hypertension and oesophageal varices have been reviewed and set in relation to international publications. RESULTS The Danish papers have mainly contributed with controlled clinical trials concerning both primary and secondary prophylaxis. Furthermore, they have dealt with pathophysiologic, clinical and experimental studies concerning portal haemodynamics and the evolution and treatment of variceal bleeding. CONCLUSION The Danish studies have been well designed and are frequently cited. Further prospective randomized studies in the new treatment modalities are encouraged.

Abstract
BACKGROUND The option of using direct compression to arrest haemorrhage from an oesophageal varix was introduced by Westphal in 1930. Since then, different types of oesophageal and or gastric balloons have become available for use. The published data concerning the efficacy and complications of the balloon tamponade in the treatment of variceal haemorrhage is evaluated. METHOD-RESULTS: Balloon tamponade as a single therapy may control initial variceal haemorrhage in more than 80% of cases. However, haemostasis is usually transient and is associated with a high rate of complications. As regards the comparison of balloon tamponade with vasoactive drugs such as vasopressin alone or vasopressin + terlipressin or terlipressin + nitroglycerin, it appears that both regimens are comparable in respect to initial control of bleeding, rebleeding, mortality, and complications. There is also evidence suggesting that balloon tamponade is as equally effective as octreotide and somatostatin in the initial control of variceal haemorrhage, but early rebleeding and complications are significantly less with the administration of both drugs. Finally, it appears that balloon tamponade is inferior to endoscopic sclerotherapy in both the acute and the long-term control of variceal haemorrhage. CONCLUSIONS Balloon tamponade should be reserved for those patients with variceal haemorrhage in whom bleeding continues despite conservative treatment, or as the first form of treatment only if sclerotherapy is not available.

Abstract
About 30% to 35% of patients with portal hypertension bleed from gastroesophageal varices and mortality remains high reflecting the challenges of effectively dealing with the bleeding event itself and the problems of underlying liver disease. Careful resuscitation and control of risk of complications is the most essential element of medical therapy (Fig. 2). Use of newer, more effective drug combinations with vasopressin or somatostatin permit control of hemorrhage in the majority of patients with fewer drug-induced complications. Endoscopic sclerotherapy and, more recently, banding therapy provide immediate control of hemorrhage and eradication of varices and rebleeding in up to 90% of patients. Persistent, recurrent bleeding in the small number of remaining patients can be effectively managed by "portacaval shunt rescue" or orthotopic liver transplantation in selected cases with acceptable surgical morbidity and mortality. The contribution and role of the TIPS procedure is unknown but very promising; at least as a bridge procedure in patients awaiting transplantation. Until appropriate prospective, comparative trials are performed, the role of TIPS as a long-term alternative to portacaval shunt surgery or other endoscopic or surgical options remains unknown.

Abstract
One hundred and fifty cirrhotic patients with or without esophageal varices and/or gastric varices were investigated by endoscopy and hepatic venous catheterization to evaluate differences in the degree of portal hypertension, main portal venous diameter and frequency of portal systemic encephalopathy. Hemodynamic values were correlated with varices size as assessed by endoscopy. Patients with large gastric varices had wedged hepatic venous pressures and hepatic venous pressure gradients which were lower than patients with esophageal varices only, but similar to patients without varices. In addition, in patients with large gastric varices, a decrease in the diameter of the main portal vein and an increase in the incidence of chronic portal systemic encephalopathy were noted. Our results implied that patients with large gastric varices presented different hemodynamic features including the degree of portal hypertension and the incidence of portal systemic encephalopathy from patients with esophageal varices only.

Abstract
Bleeding from esophageal varices exacts a high mortality and extraordinary societal costs. Prophylaxis--medication, sclerotherapy, or shunt surgery to prevent an initial bleeding episode--is ineffective. In patients who have bled from varices, endoscopic injection sclerotherapy can control acute bleeding in more than 90% of patients. Because recurrent bleeding frequently occurs and survival without definitive therapy is dismal, selection of a permanently effective treatment is mandatory once variceal bleeding has been controlled. Long-term injection sclerotherapy can be performed in compliant patients; it is relatively safe but is associated with a 30-50% rebleeding rate. Beta-blockers significantly reduce portal pressure and recurrent bleeding but have not been shown to diminish mortality from BEV. Portal decompressive surgery permanently halts bleeding in more than 90% of patients; the risk of operative mortality is high in decompensated cirrhotics, and long-term complications of encephalopathy and accelerated liver failure may limit indications for shunt surgery to good-risk cirrhotics who are not liver transplant candidates. Devascularization procedures have a low operative mortality and encephalopathy rate but unacceptably high rates of recurrent bleeding. Liver transplantation is curative therapy for bleeding esophageal varices and the associated underlying hepatic dysfunction; cost and availability of donor organs generally limit its use in this setting to variceal bleeders with end-stage liver disease not associated with active alcoholism.

Abstract
This randomized controlled trial was conducted to compare the efficacy of intravenous infusion of octreotide (a synthetic long-acting somatostatin analogue) with vasopressin in 48 cirrhotic patients with endoscopically proven bleeding esophageal varices. Twenty-four patients received a continuous infusion of octreotide 25 micrograms/h for 24 h after an initial bolus of 100 micrograms and another 24 patients received a continuous infusion of vasopressin 0.4 U/min for 24 h. Bleeding was initially controlled after 6 h of drug infusion in 88% (21/24) and 54% (13/24) of the patients treated with octreotide and vasopressin respectively (p = 0.03). Complete control of bleeding after 24 h of drug infusion was achieved in 15 (63%) patients receiving octreotide and in 11 (46%) patients receiving vasopressin (p > 0.05). Side effects during drug infusion such as headache, chest pain and abdominal pain were significantly lower in the octreotide group (3/24) than in the vasopressin group (11/24). Serum gastrin and insulin levels fell significantly following octreotide infusion, but plasma glucose levels remained unchanged. Mortality related to bleeding esophageal varices was no different between the two groups. This report showed that octreotide infusion was more effective and had fewer side effects than vasopressin in initial controlling of acute esophageal variceal bleeding until an elective endoscopic sclerotherapy could be performed.

Abstract
Since previous reports have suggested that somatostatin may be of value in the control of acute variceal haemorrhage, we compared its efficacy with that of injection sclerotherapy in a randomised controlled clinical trial. Eighty consecutive patients with endoscopically-proven severe variceal bleeding were randomised to injection sclerotherapy (n = 41) or somatostatin (n = 39) given as a continuous infusion of 250 micrograms/h for 5 days plus daily bolus administration of 250 micrograms. The efficacy of injection sclerotherapy and somatostatin infusion in controlling haemorrhage and preventing rebleeding (censored at 5 days), mortality (censored at 28 days) and complications was compared. The aetiology of the portal hypertension and transfusion requirements was similar between the two groups, but there were more patients with severe liver disease (Child's C) in the somatostatin group. There was no significant difference between the two treatments in the initial (p = 1.0) or overall control of bleeding (p = 0.58). Furthermore, somatostatin was as effective as injection sclerotherapy in controlling bleeding in patients with severe liver disease or in those actively bleeding at the time of their endoscopy. The relative risk of rebleeding whilst receiving somatostatin compared to injection sclerotherapy was 1.39 [95% Confidence Interval (CI) 3.73; 0.52], but this was reduced to 0.98 (95% CI 0.37; 2.67) when readjusted for Child's grading, the only prognostic factor shown to be of significance. Mortality was not significantly different between the two groups of patients (p = 0.31). The relative risk of dying whilst receiving somatostatin compared to injection sclerotherapy was 1.6 (95% CI 3.93; 0.66) but was reduced to 1.03 (95% CI 0.47; 2.47) when adjusted for Child's grading, the only significant prognostic factor. Complications in the somatostatin group were minor and less frequent than after injection sclerotherapy. The results of this study indicate that somatostatin is a safe treatment, which is as effective an endoscopic injection sclerotherapy for acute variceal bleeding.

Abstract
Successful pharmacological arrest of haemorrhage might avoid the risk of aspiration associated with tamponade and early studies have suggested that the vasoactive agent somatostatin may be as effective and perhaps safer than tamponade in controlling variceal haemorrhage. In our view, vasopressin has not established a role in management but we retain an open mind regarding the potential use of terlipressin in combination with nitroglycerin. It is unlikely that any of these agents can improve significantly our ability to control variceal haemorrhage when compared to balloon tamponade but they may reduce the incidence of pulmonary complications and thereby reduce subsequent mortality. Tamponade has proved successful in controlling acute haemorrhage from oesophageal varices in our hands. Late complications continue to give cause for concern but until effective safe alternatives to tamponade are developed, we continue to advocate its use for emergency control of acute variceal haemorrhage. Our own studies have shown that the high mortality seen in this patient population may reflect the severity of the underlying liver disease rather than failure of a management policy employing oesophageal tamponade for the initial control of acute variceal haemorrhage.

Abstract
Timely treatment of bleeding esophageal varices with balloon tamponade effectively achieves initial hemostatis. However, therapeutic endoscopy and sclerotherapy in patients with acute upper gastrointestinal hemorrhage is associated with better short- and long-term follow-up. We describe the technique of esophagogastric balloon insertion, as well as principles of monitoring and maintenance. The different types of balloons for tamponade are described, as well as potential complications.

Abstract
We measured the hemodynamic effects of intravenous vasopressin, ketanserin (a 5-hydroxytryptamine-2 receptor blocker), and vasopressin plus ketanserin in 33 patients with hepatitis B-related cirrhosis. Thirteen patients received vasopressin alone (0.66 units/min), ten patients ketanserin alone (10 mg), and ten patients vasopressin followed by vasopressin plus ketanserin. Vasopressin alone reduced the hepatic venous pressure gradient (from 18 +/- 5, mean +/- S.D., to 9 +/- 3 mmHg, p less than 0.0001) and cardiac output (p less than 0.0001), but increased mean arterial pressure (p less than 0.005), mean pulmonary arterial pressure (p less than 0.0001), pulmonary capillary wedge pressure (p less than 0.0001), and systemic vascular resistance (p less than 0.001). There was no significant change in heart rate. Ketanserin alone produced a significant fall in the hepatic venous pressure gradient (from 16 +/- 4 to 13 +/- 3 mmHg, p less than 0.0001), mean arterial pressure (p less than 0.005), mean pulmonary arterial pressure (p less than 0.005), and pulmonary capillary wedge pressure (p less than 0.005). Heart rate, cardiac output, and systemic vascular resistance were not significantly changed. The addition of ketanserin to vasopressin corrected most of the systemic hemodynamic disturbances produced by vasopressin. This combination did not lead to a further reduction in the hepatic venous pressure gradient. We conclude that intravenous ketanserin reduces portal pressure in patients with hepatitis B-related cirrhosis. The addition of ketanserin to vasopressin improves the detrimental systemic hemodynamic effects of vasopressin without further reducing the portal pressure.

Abstract
A randomized controlled trial was designed to investigate whether a high dose of terlipressin could control acute variceal haemorrhage more effectively than a low dose of terlipressin. Forty cirrhotic patients with bleeding oesophageal varices were included, with low-dose terlipressin in 21 patients and high-dose terlipressin in 19 patients. The two groups of patients were similarly matched for all parameters on admission. High-dose terlipressin (84%) seemed to be more effective in the initial control of bleeding than low-dose terlipressin (67%); however this difference was not significant. Complete control of bleeding during 24 h of drug infusion was achieved in 53% of patients receiving high-dose terlipressin and in 48% of those treated with low-dose terlipressin (P greater than 0.05). There were no major complications in either group. Mortality in relation to variceal bleeding and transfusion requirements were similar in the two groups. This study shows that high dose terlipressin is not superior to low dose terlipressin in acute variceal bleeding.

Abstract
The aim of this study was to compare the efficacy of: (i) somatostatin infusion, (ii) balloon tamponade with the Sengstaken-Blakemore tube and (iii) the combination of both methods, in the management of acute variceal haemorrhage. Ninety-two consecutive patients with liver cirrhosis who proved to have active variceal bleeding on emergency endoscopy were studied. Thirty-one patients were randomly assigned to an intravenous infusion of 250 micrograms/h of somatostatin (Group I), 30 to the Sengstaken-Blakemore tube (Group II) and 31 to the combination of both methods (Group III). Somatostatin was administered for 24 h, while the gastric and esophageal balloons remained inflated for 48 and 24 h, respectively, then deflated. Patients were under observation for a further 24-h period after withdrawal of treatment. If bleeding recurred, the same treatment was repeated in each group. Following treatment the bleeding was controlled initially in 22 patients (71%) in Group I, in 24 (80%) in Group II and in 25 (80.6%) in Group III. In Group II a significantly (p less than 0.05) higher proportion of patients (14/24) rebled as compared to Groups I (5/22) and III (6/25). Bleeding was controlled following retreatment in four, ten and five patients of the three respective groups. There were marked differences, in the number of complications noticed with each form of therapy. Only three patients (9.7%) in Group I developed complications (p less than 0.05) as compared to ten (33%) in Group II and ten (32%) in Group III. Hospital mortality in all three treatment groups was not significantly different.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Bleeding from esophagogastric varices carries a high mortality rate. Active variceal bleeding can usually be temporarily controlled medically with a combination of intravenous vasopressin and nitroglycerin, with balloon tamponade, or with endoscopic sclerotherapy. Because of the high likelihood of recurrence, long-term treatment, such as repeated sclerotherapy, propranolol therapy, or shunt surgery, is necessary. The proper selection of such measures requires consideration of the site of variceal bleeding, local availability of specialized techniques, and patient factors. Only liver transplantation reverses the liver damage and offers hope of improved long-term survival. As success at identifying high-risk patients by endoscopic features improves, propranolol or other pharmacologic prophylaxis may become an acceptable treatment.

Abstract
Vasopressin infusion and esophageal tamponade are still widely used to arrest variceal bleeding, but no objective evidence exists on the superiority of either of the two procedures. In this study, 108 cirrhotic patients bleeding from varices were included in a prospective, randomized trial to investigate the comparative effectiveness and safety of balloon tamponade (using the Sengstaken-Blakemore tube for esophageal varices and the Linton-Nachlas tube for gastric varices) (n = 52) and intravenous vasopressin infusion (0.4 to 0.8 mu/min) plus intravenous nitroglycerin infusion (40 to 400 micrograms/min) (n = 56). Both treatments were maintained for 24-hr. The hemostatic efficacy according to the intention to treat was 86.5% for tamponade and 66% for pharmacological therapy (p less than 0.01). No significant differences were found with respect to rebleeding during the first 72 hr after treatment, mortality rate or side effects. These results suggest that esophageal tamponade is more effective than vasopressin/nitroglycerin infusion in the treatment of variceal bleeding in cirrhotic patients.

Abstract
The nonoperative management of acute variceal hemorrhage can control acute hemorrhage and allow stabilization of the patient prior to definitive therapy to prevent further bleeding episodes. Balloon tamponade, endoscopic sclerotherapy, and pharmacotherapy can stop acute variceal bleeding. Endoscopic sclerotherapy has the highest reported success rate, decreases the incidence of early rebleeding, and is the recommended first method to control bleeding.

Abstract
A randomized trial was undertaken to determine the efficacy of nitroglycerin in addition to terlipressin infusion to improve the control of acute variceal hemorrhage compared with balloon tamponade. Forty-seven bleeding episodes in 34 cirrhotic patients were included, with terlipressin plus sublingual nitroglycerin in 23 episodes (group I) and balloon tamponade in 24 episodes (group II). At the end of the 12-hr period, hemorrhage had been equally controlled in both groups (18 of 23; 78% in group I and 19 of 24; 79% in group II). When attempted, balloon tamponade appeared more efficient in the failures of group I (4 of 4) than did terlipressin plus nitroglycerin in the failures of group II (0 of 3), although this difference was not significant. Major complications were rare (one in each group) and never required cessation of therapy. Thus terlipressin and nitroglycerin were as effective as balloon tamponade in controlling variceal hemorrhage and were associated with few minor complications.

Abstract
Vasopressin is a potent vasoconstrictor which greatly reduces mesenteric blood flow. In patients with portal hypertension this results in decreased portal venous flow and portal pressure. Because of this property, vasopressin has been used for years in the therapy of variceal haemorrhage. A few controlled trials show that vasopressin causes a decrease in bleeding but has no effect on survival. It has been shown that intravenous vasopressin is just as effective as intra-arterial, and is associated with fewer complications. The inability to influence the outcome of variceal haemorrhage significantly may be related to suboptimal dosing due to the occurrence of systemic complications at higher doses. The combination of vasopressin with either sodium nitroprusside or nitroglycerin (glyceryl trinitrate) has resulted in a further decline of portal pressure, along with amelioration of most of the adverse haemodynamic effects of vasopressin. Whether or not clinical efficacy is increased when vasopressin is combined with sodium nitroprusside or nitroglycerin remains to be proven. Analogues of vasopressin, such as terlipressin, held early promise as agents which would be as effective as vasopressin, without the cardiac adverse effects. Recent data have not supported this and at present there is little to suggest any advantage of terlipressin over vasopressin. Virtually no adequate studies have yet been performed to support the use of vasopressin in the treatment of non-variceal haemorrhages. There is reason to suspect that vasopressin can effectively control bleeding from haemorrhagic gastritis, but the subsequent results of inducing gastric ischaemia in an already damaged gastric mucosa are unknown. In summary, vasopressin appears to have little effect on the mortality of patients with variceal haemorrhage. It may, however, help control the haemorrhage in some patients by lowering the portal pressure. Cardiovascular complications limit the dose that can be used but it is hoped that by combining vasopressin with nitroglycerin, a more effective and safe therapy will be available for variceal haemorrhages.

Abstract
The treatment by Western countries of bleeding from esophageal varices was reviewed from three definite viewpoints: prevention of first bleeding or prophylactic treatment, control of acute bleeding or emergency treatment, and prevention of rebleeding or elective treatment. Even though prophylactic surgery has been abandoned on the basis of several randomized studies, some authors still perform esophageal transection and report encouraging results. In emergency situations, the role of surgery has been limited by the prohibitive hospital mortality and by the introduction of vasoactive drugs and endoscopic sclerotherapy. Nevertheless, good immediate and long term results have been obtained in specialized centers in which bleeding patients undergo surgery no later than 8 hours after their admission. As regards the prevention of rebleeding, non selective portal decompression gives adequate protection against rebleeding, however, hepatoencephalopathy follows in considerable incidence. In order to avoid this complication, direct operations on varices have been performed, largely with good results. The Warren shunt offers results showing advantage over the non-selective shunt in the first postoperative period but later on, it behaves hemodynamically as a total shunt and the advantage is then cancelled. We report herein a review of the literature and also describe our personal experience with treating bleeding esophageal varices.

Abstract
The haemodynamic effects and clinical uses of drugs used in the management of patients with oesophageal variceal bleeding are reviewed. Vasoconstrictor agents (vasopressin, teripressin) alone or in combination with nitrates continue to be used for acute bleeding episodes, while somatostatin is an alternative. Alpha- and beta-adrenergic blocking drugs and vasodilators which lead to a sustained decrease in portal pressure can be used for the prevention of bleeding episodes, but despite numerous studies the pharmacological treatment of variceal bleeding remains controversial.

Abstract
Triglycyl-lysin-vasopressin is a long-acting vasopressin derivative which is under consideration for the treatment of acute variceal bleeding in cirrhosis. However, its splanchnic hemodynamic effects have not been investigated thoroughly. In 11 patients with alcoholic cirrhosis, systemic and splanchnic hemodynamics were evaluated before and 20-40 min after intravenous administration of 2 mg triglycyl-lysin-vasopressin. Following the drug administration, heart rate decreased by 10% and cardiac index by 22% on the average, respectively; mean arterial pressure increased by 14% and systemic vascular resistence index by 48%. Hepatic venous pressure gradient showed a marked and persistent fall, averaging 31%. Hepatic and splenic blood flow decreased by 31% and 56%, respectively. A significant correlation was found between the decrease in hepatic venous pressure gradient and in splenic blood flow. By contrast, the decrease in the hepatic venous pressure gradient was not significantly correlated to the decrease in hepatic blood flow or in cardiac index. We conclude that in patients with alcoholic cirrhosis, triglycyl-lysin-vasopressin decreases portal pressure as well as hepatic and splenic blood flows. The decrease in portal pressure was due to the decrease in splanchnic blood inflow and not to the decrease in cardiac index.

Abstract
The efficacy and complications of esophageal tamponade as the first procedure in the routine management of acute variceal hemorrhage were evaluated in 151 consecutive bleeding episodes treated at a specialized unit. The Sengstaken-Blakemore tube was employed in the 118 cases in which emergency endoscopy demonstrated bleeding esophageal varices, and the Linton-Nachlas balloon in the 33 cases with bleeding from gastric varices. Hemostasis lasting at least 24 hr was obtained in 91.5% of cases treated with the Sengstaken-Blakemore balloon and in 88% of those treated with the Linton-Nachlas balloon. Permanent hemostasis was obtained in 47.7% of all cases. The only severe complication noted in these 151 episodes of bleeding treated by tamponade was pulmonary aspiration, which was detected in 10% of cases. This complication was related to the presence and degree of encephalopathy (P less than 0.001) and was prevented by orotracheal intubation prior to tamponade. These results indicate that balloon tamponade continues to be a reliable and valuable method to arrest bleeding from esophagogastric varices.

Abstract
Seventy consecutive cirrhotic patients with persistent or recurrent variceal bleeding were included in a clinical trial to compare the efficacy and safety of portacaval shunt (PCS) and stapler transection (ST) in patients with low surgical risk, and of stapler transection and endoscopic sclerotherapy (ES) in patients with high surgical risk. To classify the patients into low- and high-risk groups a new scoring system was used, based on an analysis of factors influencing operative mortality in an earlier series of emergency portacaval shunt. Thirty-eight low-risk patients were randomly allocated for treatment with portacaval shunt (19 patients) or stapler transection (19 patients), and 32 high-risk patients for stapler transection (17 patients) or ES (15 patients). The operative mortality of patients treated by PCS was close to that expected according to retrospective data, this indicating that the proposed scoring system is highly discriminant. In low-risk patients, portacaval shunt evidenced greater haemostatic efficacy and fewer complications than stapler transection. However, hepatic encephalopathy during follow-up was more frequent in the portacaval shunt group and there were no significant differences in operative mortality and long-term survival between the two groups. In high-risk patients, stapler transection and sclerotherapy had a similar haemostatic efficacy, operative mortality and long-term survival. However, sclerotherapy occasioned fewer complications than stapler transection. Our results motivate us to recommend stapler transection for low-risk patients and to consider sclerotherapy as an alternative for high-risk patients in the emergency treatment of uncontrolled variceal bleeding.

Abstract
Vasopressin has been in clinical use for more than two decades in the treatment of upper gastrointestinal haemorrhage, especially bleeding oesophageal varices. However the haemostatic effect in controlled clinical trials is far from impressive, and no double-blind placebo controlled trial has shown even a trend in favour of vasopressin. These studies, the effects, side-effects, and clinical use of vasopressin and its long-acting analogue triglycylvasopressin, glypressin, are reviewed.

Abstract
Numerous prospective randomized trials have failed to demonstrate a benefit attributable to early diagnostic esophagogastroduodenoscopy (EGD) in acute upper gastrointestinal bleeding (UGIB). The clinical implications of these studies have received extensive editorial comment and analysis. We have employed a probability model to further analyze the reasons why these studies have failed to demonstrate an impact of EGD on UGIB. The clinical course of each bleeding lesion can be predicted from the literature. For each lesion, the mortality associated with early specific intervention afforded by an early specific diagnosis can be compared with the mortality of intervention delayed by applying EGD only to those patients who have a complicated course marked by continued bleeding or rebleeding. Using optimistic assumptions that would tend to overstate the impact of EGD, this analysis estimates the maximum decrease in overall mortality in any of these trials afforded by early diagnostic EGD to be 1.2% which would require randomization of over 5000 patients to demonstrate this benefit in a prospective trial.

Abstract
Thirty-nine patients admitted during a 16-month period for acute bleeding from varices confirmed by emergency endoscopy were randomized to receive either continuous intravenous infusions of vasopressin alone (0.66 units per min) (Group I: 19 patients) or vasopressin plus sublingual nitroglycerin (0.6 mg every 30 min for 6 hr) (Group II: 20 patients). The two groups of patients were similar in the type and severity of their cirrhosis. Bleeding was controlled initially in 47% (9/19) of the patients in Group I and 55% (11/20) of the patients in Group II after 6 hr of infusion (not statistically significant). Complete control of bleeding during 24 hr of infusion was achieved in only 4 of 19 patients in Group I (21%) but in 9 of 20 in Group II (45%). This difference is not statistically significant. The total number of patients with complications during infusions were significantly different statistically in the vasopressin and vasopressin-nitroglycerin groups, respectively (17/19 vs. 7/20, p less than 0.001). Major complications requiring immediate cessation of infusions were observed in 6 of 19 of the patients in Group I (32%) and in 2 of 20 in Group II (10%) (p less than 0.05). Mortality (58% in Group I, 55% in Group II) and transfusion requirements were similar in the two groups. This study shows that the addition of sublingual nitroglycerin to intravenous vasopressin does not alter the efficacy of vasopressin alone in controlling hemorrhage from esophageal varices, but it does significantly reduce the complications.
