Background: The extent to which patients with acute variceal bleeding (AVB) receive recommended care is largely unknown., Aim: to evaluate the adherence of the 4 major Baveno VI recommendations [vasoactive agents, prophylactic antibiotic, esophagogastroduodenoscopy (EGD) within 12 hours, endoscopic variceal ligation (EVL)] as a marker of quality of an emergency model., Methods: Retrospective evaluation of AVB admissions to a tertiary centre in which endoscopy was available 24hours-a-day, with a regional out-of-hours service at night (the furthest hospital is 200Km away). Patients were divided in directly admitted or transferred from other centres., Results: 210 AVB patients were included; 101 (48.1%) were directly admitted. The majority of patients were submitted to vasoactive agents (85.7%) and prophylactic antibiotics (79%) before EGD. In 178 patients (84.8%) endoscopy was performed within 12h and EVL was the procedure of choice in 116 (74.8%) (only oesophageal varices). No significant differences were observed between directly admitted and transferred patients in adherence rates. Overall rebleeding rate was 8.6%, in-hospital mortality 11.4% and 6-week mortality 20%., Conclusion: Adherence to quality metrics was high which might have played a vital role for reported outcomes. These results suggest that this model of care, provides accessibility and equity in access to urgent endoscopy., Competing Interests: Declaration of Competing Interest The authors have no conflict of interests to declare., (Copyright © 2021 Editrice Gastroenterologica Italiana S.r.l.

Background: Complications of patients with liver disease generally occurs as the consequence of advanced fibrosis and portal hypertension. Non-invasive tools to predict the complications may allow for better risk-stratification and medical management in patients with cirrhosis. The goals of this study were to determine the utility of CT-scan based liver and spleen volume measurement in association with complications and outcomes in patients with cirrhosis., Methods: Baseline demographic and clinical characteristics of 556 patients with cirrhosis who underwent CT scan of the abdomen between January 1-June 30,2009 were reviewed. Liver and spleen volume were measured using semi-automated interactive software and compared to 47 healthy controls. The association between liver and spleen volume and complications of cirrhosis was determined. Independent predictors of survival were analyzed with Cox regression model., Results: Patients with cirrhosis had significantly lower total and functional liver volume, larger total and functional spleen volume, and significantly lower total liver to spleen volume ratio when compared to controls. Liver volume, spleen volume, and liver to spleen volume ratio were significantly altered in patients with decompensated stage. Patients with hepatic encephalopathy had significantly lower total liver volume and spleen size was associated with the presence of esophageal varices. Patients with cirrhosis who underwent liver transplantation had significantly lower total liver volume and larger total spleen volume. However, spleen volume was not an independent predictor for mortality., Conclusions: Baseline liver and spleen volume and its ratio are significantly altered in patients with cirrhosis. Spleen volume is also associated with the presence of esophageal varices., Competing Interests: Declaration of Competing Interest The authors declare that they have no competing interests., (Copyright © 2020 Southern Society for Clinical Investigation.

Background & Aims: Antibiotic prophylaxis reduces the risk of infection and mortality in patients with cirrhosis and acute variceal bleeding (AVB). This study examines the incidence of, and risk factors for, bacterial infections during hospitalization in patients with AVB on antibiotic prophylaxis., Methods: A post hoc analysis was performed using the database of an international, multicenter, observational study designed to examine the role of pre-emptive transjugular intrahepatic portosystemic shunts in patients with cirrhosis and AVB. Data were collected on patients with cirrhosis hospitalized for AVB (n = 2,138) from a prospective cohort (October 2013-May 2015) at 34 referral centers, and a retrospective cohort (October 2011-September 2013) at 19 of these centers. The primary outcome was incidence of bacterial infection during hospitalization., Results: A total of 1,656 patients out of 1,770 (93.6%) received antibiotic prophylaxis; third-generation cephalosporins (76.2%) and quinolones (19.0%) were used most frequently. Of the patients on antibiotic prophylaxis, 320 patients developed bacterial infection during hospitalization. Respiratory infection accounted for 43.6% of infections and for 49.7% of infected patients, and occurred early after admission (median 3 days, IQR 1-6). On multivariate analysis, respiratory infection was independently associated with Child-Pugh C (odds ratio [OR] 3.1; 95% CI 1.4-6.7), grade III-IV encephalopathy (OR 2.8; 95% CI 1.8-4.4), orotracheal intubation for endoscopy (OR 2.6; 95% CI 1.8-3.8), nasogastric tube placement (OR 1.7; 95% CI 1.2-2.4) or esophageal balloon tamponade (OR 2.4; 95% CI 1.2-4.9)., Conclusion: Bacterial infections develop in almost one-fifth of patients with AVB despite antibiotic prophylaxis. Respiratory infection is the most frequent, is an early event after admission, and is associated with advanced liver failure, severe hepatic encephalopathy and use of nasogastric tube, orotracheal intubation for endoscopy or esophageal balloon tamponade., Lay Summary: Bacterial infections develop during hospitalization in close to 20% of patients with acute variceal bleeding despite antibiotic prophylaxis. Respiratory bacterial infections are the most frequent and occur early after admission. Respiratory infection is associated with advanced liver disease, severe hepatic encephalopathy and a need for a nasogastric tube, orotracheal intubation for endoscopy or esophageal balloon tamponade., Competing Interests: Conflicts of interest Juan Carlos Garcia-Pagan has consultant fees for GORE, Shionogi and Cook grants from GORE and Novartis.

Background & Aims: There are no data validating the performance of spleen stiffness measurement in ruling out high-risk varices in patients with HBV-related cirrhosis under maintained viral suppression. Thus, we aimed to prospectively validate the performance of spleen stiffness measurement (cut-off 46 kPa) combined with Baveno VI criteria in ruling out high-risk varices in these patients., Methods: Patients with cirrhosis were enrolled from April to December 2019 at the hepatology unit of the Nanfang Hospital, China. Liver and spleen transient elastography and esophagogastroduodenoscopy were performed at enrollment. Antiviral regimen(s) and virological responses, evaluated every 3-6 months, were recorded., Results: Overall 341 patients with HBV-related cirrhosis under maintained viral suppression were enrolled, and the prevalence of high-risk varices was 20.5% (70/341). Baveno VI criteria spared 37.0% (126/341) esophagogastroduodenoscopies and no high-risk varices were missed (0/70). Eight cases of high-risk varices (8/70, 11.4%) were misclassified in patients (208/341, 61.0%) within the expanded Baveno VI criteria. The spleen stiffness measurement cut-off (≤46.0 kPa) was shown to safely rule out high-risk varices in these patients (the percentage of missed high-risk varices was 4.3%). Over half (61.6%, 210/341) of patients met the combined model (Baveno VI criteria and spleen stiffness measurement cut-off ≤46 kPa) and 4.3% (3/70) of high-risk varices cases were misclassified. This combined model exhibited a sensitivity of 95.71%, specificity of 76.38%, negative predictive value of 98.57%, and negative likelihood ratio of 0.06 for ruling out high-risk varices., Conclusions: We validated the excellent performance of Baveno VI criteria combined with spleen stiffness measurement (cut-off 46 kPa) for safely ruling out high-risk varices in patients with HBV-related cirrhosis under viral suppression; more than half of esophagogastroduodenoscopy procedures were spared using this combination., Clinical Trial Number: NCT04123509 LAY SUMMARY: Esophageal varices have important prognostic implications in patients with cirrhosis. Thus, their timely identification is important so that treatment can be initiated early. Herein, we validated the excellent performance of the combination of Baveno VI criteria with spleen stiffness measurement (cut-off 46 kPa) for ruling out high-risk esophageal varices in patients with HBV-related cirrhosis under maintained viral suppression (with antiviral treatment). This combined model was able to safely rule out high-risk varices (missed/total <5%) and over half (61.6%) of esophagogastroduodenoscopy procedures were spared., Competing Interests: Conflict of interest The authors declare no conflicts of interest that pertain to this work.

Introduction: Management of portal vein thrombosis (PVT) in cancer patients remains discussed., Aims: The objective of this multicenter retrospective study was to investigate the management and outcome of PVT in patients with digestive cancers other than hepatocellular carcinoma (HCC)., Method: Main inclusion criteria were trunk or branch PVT in patients with locally advanced or metastatic digestive cancers. Predictive factors of bleeding and overall survival (OS) were evaluated in univariate and multivariate analysis., Results: Between 2012 and 2016, 118 patients with PVT and digestive cancers were identified. The majority had a pancreatic cancer (50%). Sixty-six percent of patients had trunk PVT location. Endoscopic screening of portal hypertension was performed in only 7 patients (1%) and 5 had esophageal varices. Gastrointestinal bleeding occurred in 22 patients (19%) and 12 patient deaths (17%) were related to a gastrointestinal hemorrhage. Metastatic disease (HR=2.83 [95%CI 1.47-5.43], p<0.01) and gastrointestinal hemorrhage (HR=1.68 [95%CI 1.01-2.78], p=0.04) were associated with OS in multivariate analysis. Only trunk PVT location was significantly associated with gastrointestinal hemorrhage in multivariate analysis (HR=5.56 [95%CI 1.18-26.32], p=0.03)., Conclusion: A high rate of variceal bleeding leading to death was found in this cohort. Endoscopic screening and the efficacy of prophylactic treatment of variceal bleeding remain to be evaluated in a prospective study., (Copyright © 2017 Editrice Gastroenterologica Italiana S.r.l.

Background & Aims: Esophageal varices (EV) are a marker of disease severity in compensated cirrhosis due to hepatitis B virus (HBV) which predicts also the risk of hepatocellular carcinoma (HCC), clinical decompensation and anticipated liver related death. The dynamics and prognostic significance of EV in patients under long-term HBV suppression by nucleos(t)ide analogs (NUC), are poorly known., Methods: A standardized protocol (Baveno) including 414 upper gastrointestinal (GI) endoscopies was applied to 107 HBeAg-negative compensated cirrhotic patients (93% Child-Pugh A) during a median of 12 (range 2 to 17) years of NUC therapy. Patients who initially started on lamivudine (LMV) and then developed resistance (LMV-R), were rescued by early administration of adefovir, or were switched to tenofovir. Surveillance included serum HBV DNA every three months and abdominal ultrasound every six months., Results: Twenty-seven patients had baseline F1 EV which regressed in 18, remained unchanged in eight and progressed in one patient; the 12-year cumulative incidence of EV regression was 83% (95% CI: 52-92%). De novo F1/F2 EV developed in 6/80 patients with a 12-year cumulative incidence of 10% (95% CI: 5-20%). Six of seven patients with de novo varices or progression of pre-existing varices had either a clinical breakthrough due to LMV-R and/or developed a HCC. No bleedings from ruptured EV occurred, 12 patients died (9 HCC) and 15 were transplanted (13 HCC): the 12-year cumulative incidence of HCC and overall survival was 33% (95% CI: 24-42%) and 76% (95% CI: 67-83%), respectively., Conclusions: Long-term pharmacological suppression of HBV in HBeAg-seronegative patients with compensated cirrhosis leads to a significant regression of pre-existing EV accompanied by a negligible risk of developing de novo EV., (Copyright © 2015 European Association for the Study of the Liver.

Objective: Esophageal varices are a consequence of portal hypertension in cirrhotic patients. Current guidelines recommend that all cirrhotic patients undergo screening endoscopy at diagnosis to identify patients with varices at high risk of bleeding who will benefit from primary prophylaxis. This practice increases costs, involves a degree of invasiveness and discomfort and places a heavy burden on endoscopy units. Several studies have evaluated possible noninvasive predictors of esophageal varices, but most of these studies remain controversial., Methods: The intra-abdominal portion of the esophagus in 673 patients who presented with liver cirrhosis and portal hypertension was examined using standard 2-dimensional (2D) ultrasound. A direct relationship between the degree of varices observed on upper endoscopy and the intra-abdominal esophageal wall thickness was detected using 2D ultrasound., Results: The mean thicknesses of the esophageal wall were 3.7 ± 0.5 mm (mean ± standard deviation) in normal individuals, 7.3 ± 3.3 mm in those with esophageal varices and 8.65 ± 1.98 mm in those with risky esophageal varices. The overall accuracy of 2D ultrasound was 95%., Conclusions: The intra-abdominal esophagus should be observed during abdominal ultrasound examination in patients with liver cirrhosis. Two-dimensional ultrasound can play an important role in screening for esophageal varices.

Upper digestive bleeding is one of the most serious complications of mansoni schistosomiasis, and portal congestive gastropathy (PCG) is responsible for 25-30% of the cases of bleeding instead of bleeding due to esophageal varices. This study aimed to investigate the association between PCG with parameters of portal hypertension and the intensity of periportal fibrosis assessed by ultrasonography, in patients with mansoni schistosomiasis. A prospective study was made of 71 patients whether or not they had a history of upper digestive bleeding, and who had not been previously treated for portal hypertension (splenectomy, use of beta blockers or endoscopic treatment). Patients with other liver diseases were excluded. After signing a form of consent, the patients underwent endoscopy, as well as ultrasonography of the abdomen, and hematological, biochemical and viral markers tests. Chi-square and Fischer's exact tests were used in the statistical analysis. The mean age of the 71 patients was 50 ± 14.5 years of whom 59.2% were women. 45.1% had antecedents of upper digestive bleeding. PCG was observed in 39 patients (54.9%): severe in 8.5%, and mild in 46.5%. A positive association was observed between PCG and the grade of esophageal varices (p=0.017); and the pattern of periportal fibrosis (p=0.041). A negative association was observed between PCG and red spots on the varices (p=0.024). PCG in patients with mansoni schistosomiasis not submitted to treatment for portal hypertension is associated with the sonographic pattern of hepatic fibrosis, as well as with the grade of esophageal varices., (Copyright © 2013 Elsevier B.V.

Background & Aims: Soluble CD163 (sCD163) is shed in the blood circulation by activated macrophages, correlates strongly with the hepatic venous pressure gradient (HVPG) and is thereby a good indicator of portal hypertension. It is unknown whether sCD163 correlates with the risk of variceal bleeding and overall survival (OS) in patients with liver cirrhosis. We performed a prospective study to investigate if sCD163 serum levels correlate with the risk of variceal bleeding and OS in cirrhotic patients., Methods: Patients with liver cirrhosis were prospectively enrolled and followed until death or last contact. At the day of inclusion in the study, blood samples were taken and sCD163 serum levels were assessed by ELISA (enzyme-linked immunosorbent assay). The time until the end points death and variceal bleeding was assessed and the risks of death or variceal bleeding were calculated with uni- and multivariate Cox regression analyses., Results: High sCD163 levels (>4100 ng/L) were associated with death independently of the MELD (model of end stage liver disease) score, CRP (C-reactive protein), age and gender. Furthermore, high sCD163 levels were associated with gastrointestinal bleeding independently of the variceal stage and red spots., Conclusions: The sCD163 serum level is a new independent non-invasive risk factor for death and variceal bleeding in cirrhotic patients., (Copyright © 2013 European Association for the Study of the Liver.

Background: Pancreatitis-induced splenic vein thrombosis (PISVT) is an acquired anatomic abnormality that impacts decision making in pancreatic surgery. Despite this influence, its incidence and the rate of associated gastrointestinal (GI) bleeding are imprecisely known., Methods: The MEDLINE, EMBASE, Cochrane Central Register of Clinical Trials and Cochrane Database of Systematic Reviews databases were searched from their inception to June 2010 for abstracts documenting PISVT in acute (AP) or chronic pancreatitis (CP). Two reviewers independently graded abstracts for inclusion in this review. Heterogeneity in combining data was assumed prior to pooling. Random-effects meta-analyses were performed to estimate percentages and 95% confidence intervals., Results: After review of 241 abstracts, 47 studies and 52 case reports were graded as relevant. These represent a cohort of 805 patients with PISVT reported in the literature. A meta-analysis of studies meeting inclusion criteria shows mean incidences of PISVT of 14.1% in all patients, 22.6% in patients with AP and 12.4% in patients with CP. The incidence of associated splenomegaly was only 51.9% in these patients. Varices were identified in 53.0% of patients and were gastric in 77.3% of cases. The overall rate of GI bleeding was 12.3%., Conclusions: Although reported incidences of PISVT vary widely across studies, an overall incidence of 14.1% is reported. Splenomegaly is an unreliable sign of PISVT. Although the true natural history of PISVT remains unknown, the collective reported rate of associated GI bleeding is 12.3%., (© 2011 International Hepato-Pancreato-Biliary Association.)

Background: Oesophagogastroduodenoscopy is currently recommended for the screening of varices in cirrhosis. In addition to the assessment of varices, oesophagogastroduodenoscopy can detect conditions that, while unrelated to portal hypertension, may require treatment., Aims: We evaluated in a large cohort of cirrhotic patients the prevalence of upper digestive findings other than oesophagogastric varices, the associations between upper gastrointestinal findings, portal hypertension and features of cirrhosis, and the incidence of new lesions in the course of a surveillance program., Methods: Analysis of the records of 611 consecutive cirrhotic patients undergoing oesophagogastroduodenoscopy for screening and surveillance., Results: 232 patients (38%) presented endoscopic lesions not related to portal hypertension: peptic diseases (n=193), proliferative diseases (n=27) and vascular diseases (n=12). In the screening group, 127 patients (39.4%) had pathologic lesions. At multivariate analysis, an association was found between peptic diseases and the absence of portal hypertensive gastropathy (RR 3.3; 95% CI 2.2-4.8); vascular diseases were associated with endoscopic signs of portal hypertension (p=0.01). During surveillance, 9/55 patients (16.3%) in the group without previous pathologic findings developed new lesions., Conclusions: Oesophagogastroduodenoscopy in patients with cirrhosis undergoing endoscopy for screening diagnosed pathologic lesions unrelated to portal hypertension requiring a change in management in 39.4% of asymptomatic subjects., (Copyright © 2010 Editrice Gastroenterologica Italiana S.r.l.

Background/aims: To determine the incidence and prevalence of cirrhosis in the United Kingdom., Methods: We identified patients aged 25 or over with cirrhosis, oesophageal varices or portal hypertension from the UK General Practice Research Database between 1992 and 2001. We measured incidence rates by sex, year and aetiology, incidence rate ratios and estimated prevalence figures., Results: Three thousand three hundred and sixty cases of cirrhosis were identified. Crude incidence was 14.55 per 100,000 person years increasing from 12.05 to 16.99 per 100,000 person years from 1992 to 2001. Incidence was over 50% higher in men compared with women (adjusted incidence rate ratio 1.52 (95%CI [1.42-1.63])). A statistically significant increase in incidence of both alcoholic cirrhosis and non-alcohol-related cirrhosis was seen in men and women. Prevalence of cirrhosis was an estimated 76.3 per 100,000 population aged over 25 in mid-2001., Conclusions: There was a 45% increase in the incidence of cirrhosis during the decade 1992-2001 in the UK and a 68% increase in prevalence. Cirrhosis occurred more commonly and at younger ages in men than women. Cirrhosis represents a growing burden of morbidity and mortality in the UK, with an estimated 30,000 people living with cirrhosis and at least 7000 new cases being diagnosed each year.

In liver cirrhosis, variceal bleeding is the last in a chain of events initiated by the increase in portal pressure (estimated in clinical practice by the hepatic venous pressure gradient). When hepatic venous pressure gradient goes above 10 mmHg the patient is at risk of developing varices, and when hepatic venous pressure gradient reaches 12 mmHg variceal bleeding might develop. Currently, there is not any effective therapy for the prevention of the development of varices. When varices are small, beta-adrenergic blockers might prevent the enlargement of the varices, and may reduce the risk of variceal bleeding. In patients with medium to large varices, beta-blockers are clearly effective in reducing the risk of variceal bleeding. Endoscopic band ligation might be more effective than beta-blockers, but available evidence is still very weak.

Objective: To investigate the influences of helicobacter pylori (Hp) infection, liver function, gastroesophageal varicosity, esophageal varicosity ligation (EVL), and esophageal varicosity sclerotherapy (EVS) on patients with portal hypertensive gastropathy (PHG)., Methods: Fourty-seven patients with liver cirrhosis included 34 patients with PHG and 13 patients without PHG. Liver function, Hp infection, and gastroesophageal varicosity were investigated clinically in all patients, and gastroscopy was made again in patients with EVL 1-2 months after operation to observe the changes of PHG., Results: The rate of Hp infection was lower in patients with liver cirrhosis than in controls. There was no relationship between Hp infection and PHG. The patients with gastroesophageal varicosity had a high incidence of PHG., Conclusions: Despite no relationship between Hp infection and PHG, liver dysfunction can affect and promote PHG. Gastroesophageal varicosity may be closely related to PHG, but their degrees are not related. PHG can be caused or promoted by EVL.

Background/aims: The incidence and natural history of small esophageal varices (EV) in cirrhotics may influence the frequency of endoscopies and the decision to start a pharmacological treatment in these patients., Methods: We prospectively evaluated 206 cirrhotics, 113 without varices and 93 with small EV, during a mean follow-up of 37+/-22 months. Patients with previous gastrointestinal bleeding or receiving any treatment for portal hypertension were excluded. Endoscopy was performed every 12 months., Results: The rate of incidence of EV was 5% (95%CI: 0.8-8.2%) at 1 year and 28% (21.0-35.0%) at 3 years. The rate of EV progression was 12% (5.6-18.4%) at 1 year and 31% (21.2-40.8%) at 3 years. Post-alcoholic origin of cirrhosis, Child-Pugh's class (B or C) and the finding of red wale marks at first examination were predictors for the variceal progression. The two-years risk of bleeding from EV was higher in patients with small varices upon enrollment than in those without varices: 12% (95% CI: 5.2-18.8%) vs. 2% (0.1-4.1%); (P<0.01). Predictor for bleeding was the presence of red wale marks at first endoscopy., Conclusions: In patients with no or small EV, endoscopy surveillance should be planned taking into account cause and degree of liver dysfunction.

The course of cirrhosis after the first episode of variceal bleeding is characterized by recurrent episodes of bleeding and bleeding-free periods, with each new stage being associated with an initially high mortality rate. Analysis of the course of this disease is usually based on traditional survival models measuring observation time from admission to hospital. This approach cannot provide valid answers to the following clinically relevant questions: 1) what is the risk of death while bleeding? 2) what is the risk of continuing bleeding? 3) what is the risk of death after bleeding has stopped? 4) what is the risk of a new bleeding episode among those who remain alive and do not bleed? and 5) do the answers to the former four questions depend on the number of previous bleeding episodes or on the time since the first episode? These questions may be addressed using the multistage, competing risks model presented here. By measuring time from the start of each new bleeding or bleeding-free period, this model synchronizes the patients with respect to disease development and, hence, to level of the rate of new clinical events. This reduces the heterogeneity of risk levels in the patient group at any given time. In an analysis of 94 patients with cirrhosis admitted for their first episode of variceal bleeding, we estimated the mortality rates during bleeding and without current bleeding, the rate of cessation of bleeding and the rate of rebleeding. The influence of number of previous rebleedings and of the time since the first bleeding was examined using a Cox regression model for competing risks.(ABSTRACT TRUNCATED AT 250 WORDS)

In order to determine the incidence of infection following sclerotherapy and the role of antimicrobial prophylaxis, a prospective randomized control study was performed comparing i.v. imipenem/cilastatin, with an infusion of dextrose-saline as a control group. One hundred patients with bleeding esophageal varices were included. All episodes of infection were documented during admission to the unit. Ninety-seven patients were evaluable. Post-sclerotherapy bacteremia developed in six (5.6%) of 107 sclerotherapy sessions in the control group and one (1.1%) of the 88 sclerotherapy sessions in the imipenem/cilastatin group (P < or = 0.1, NS): six of these seven post-sclerotherapy bacteremias occurred after emergency sclerotherapy. Infection within 7 days of the procedure was documented after 43 (22.1%) of the 195 sclerotherapy sessions, 18 (20.5%) in the imipenem/cilastatin group and 25 (23.4%) in the control group (P = NS). These infections were significantly more common after emergency sclerotherapy, 40 (34.8%) of 115 sessions, than after elective sclerotherapy, three (3.8%) of 80 sessions (P < or = 0.0001). A short prophylactic antibiotic regime does not reduce the risk of early bacteremia or the frequency of infection after sclerotherapy. The higher risk of infection after emergency sclerotherapy may be therefore related more to the gastrointestinal hemorrhage and its associated effects than to sclerotherapy.

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)
