Zhang YH, Hu B. Future directions of noninvasive prediction of esophageal variceal bleeding: No worry about the present computed tomography inefficiency. World J Gastrointest Endosc 2024; 16:108-111. [PMID: 38577650 PMCID: PMC10989247 DOI: 10.4253/wjge.v16.i3.108] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/27/2023] [Revised: 01/16/2024] [Accepted: 02/06/2024] [Indexed: 03/14/2024] Open
Abstract
In this editorial, we comment on the minireview by Martino A, published in the recent issue of World Journal of Gastrointestinal Endoscopy 2023; 15 (12): 681-689. We focused mainly on the possibility of replacing the hepatic venous pressure gradient (HVPG) and endoscopy with noninvasive methods for predicting esophageal variceal bleeding. The risk factors for bleeding were the size of the varices, the red sign and the Child-Pugh score. The intrinsic core factor that drove these changes was the HVPG. Therefore, the present studies investigating noninvasive methods, including computed tomography, magnetic resonance imaging, elastography, and laboratory tests, are working on correlating imaging or serum marker data with intravenous pressure and clinical outcomes, such as bleeding. A single parameter is usually not enough to construct an efficient model. Therefore, multiple factors were used in most of the studies to construct predictive models. Encouraging results have been obtained, in which bleeding prediction was partly reached. However, these methods are not satisfactory enough to replace invasive methods, due to the many drawbacks of different studies. There is still plenty of room for future improvement. Prediction of the precise timing of bleeding using various models, and extracting the texture of variceal walls using high-definition imaging modalities to predict the red sign are interesting directions to lay investment on.

Abstract
Background Endoscopic variceal ligation (EVL) is a surgical intervention that can work well to curb variceal bleeding in people with liver cirrhosis. However, it could make ulcer bleeding worse and be fatal in some cases. The widespread use of proton pump inhibitors (PPI) in cirrhotic individuals with variceal bleeding is empirical rather than based on scientific data. According to many studies, PPIs reduce the size of post-EVL ulcers. This study aimed to see if PPI use could reduce rebleeding after endoscopy therapy in cirrhotic patients with variceal bleeding. Methodology A retrospective cross-sectional study was conducted at a tertiary care hospital from August 2019 to September 2021. Cirrhotic patients with bleeding gastroesophageal varices (GEVs) who had undergone EVL at the same hospital were enrolled in the study. Medical records were organized, and the sample was divided into two groups based on whether or not PPI was given. Both PPI and non-PPI patients had their endoscopic findings, initial hemostasis outcomes, rebleeding rates, bleeding-related mortality rates, and treatment-related comorbidities compared. Results A total of 46 patients were selected for the study and divided into two groups (PPI group n=28 and non-PPI group n=18). The majority of the patients were males. The PPI group had a mean age of 58.6 ±7.8 years, whereas the non-PPI group had a mean age of 53.6 ±4.4 years. Hepatitis B virus (HBV) infection was the most prevalent cause of cirrhosis in both groups. After endoscopic treatment, three patients (16%) in the non-PPI group suffered a variceal hemorrhage. Bleeding-related fatalities and the time it took for the bleeding to stop varied significantly between the two groups. History of variceal bleeding (relative risk (RR)=1.45; 95% confidence interval (CI), 1.60-7.67; p=0.02), presence of gastric varices (RR=2.23; 95% CI, 2.56-9.832; p=0.035), and not administering PPIs (RR =7.542; 95% CI, 3.98-29.13; p=0.008) were linked with rebleeding. The presence of red concurrent esophageal varices (RR=6.37; 95% CI, 0.562-15.342; p=0.002) and failure to provide PPIs (RR=2.3; 95% CI, 1.621-25.64; p=0.04) were linked with post-EVL bleeding in a multivariate analysis. Conclusions Proton pump inhibitors reduce the occurrence of early bleeding and adverse events after EVL in cirrhotic patients. Not prescribing PPIs and the presence of GEVs were substantially related to a higher risk of bleeding during preventative EVL. Not initiating PPI medication immediately was the sole predictor of bleeding complications in patients who had undergone EVL without gastric varix treatment. To lower the risk of post-EVL ulcer bleeding, we recommend PPI use in patients undergoing EVL.

Early Identification of High-Risk Factors for Upper Gastrointestinal Bleeding. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:5641394. [PMID: 36276848 PMCID: PMC9584689 DOI: 10.1155/2022/5641394] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/14/2022] [Revised: 09/11/2022] [Accepted: 09/19/2022] [Indexed: 11/06/2022]
Abstract
Objective To identify simple and accurate pre-endoscopy risk factors for early identification of high-risk upper gastrointestinal bleeding. Methods Patients who were admitted to Suzhou Hospital of Integrated Traditional Chinese and Western Medicine from January 1, 2016, to December 31, 2019, due to upper gastrointestinal bleeding were retrieved, and the detailed clinical data of the above patients were collected. Patients with a definite diagnosis of bleeding from esophageal/and gastric varices were assigned to the high-risk group. Patients with bleeding not caused by varices were divided into a high-risk and a low-risk group according to the Forrest grading and scoring standard (high-risk group Forrest Ia-IIb, low-risk group Forrest IIc-III). Univariate analysis, t-test, chi-square test, binary logistic regression, ROC curve (Receiver-operating characteristic curve), etc. were employed for analysis in order to identify some simple and accurate risk factors for high-risk upper digestion tract bleeding before endoscopy. Results A total of 916 patients were collected. Three risk factors among the screened risk factors (1) hemoglobin ≤ 85 g/L, (2) vomiting red blood, and (3) “red bloody stool” were analyzed by ROC curve analysis. The specificities of each factor were 78.4%, 94.5%, and 96.7%, respectively, and the sensitivities were 71.8%, 55.9%, and 23.1%, respectively. We also derived a risk prediction scoring system for the three factors that meet the high risk such as (1) hemoglobin ≤ 83 g/L, (2)vomiting red blood, and (3) “red bloody stool.” The area under the ROC curve (AUROC), sensitivity, and specificity were 0.877, 0.904, and 0.746. Conclusion Hemoglobin ≤ 85 g/L, vomiting red blood, and red bloody stool were included in a simple scoring standard for predicting high-risk UGIB patients before endoscopy. The new risk prediction scoring system requires only three indicators and has the advantages of high accuracy, short time-consuming, and easy application.

RLLB/Alb ratio: a promising noninvasive diagnostic marker in assessing esophageal varices in cirrhotic patients. J Clin Lab Anal 2022; 36:e24589. [PMID: 35808890 PMCID: PMC9396198 DOI: 10.1002/jcla.24589] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2022] [Revised: 06/16/2022] [Accepted: 06/25/2022] [Indexed: 11/09/2022] Open
Abstract
BACKGROUND Endoscopy has long been widely used to screen for esophageal varices (EV) in cirrhotic patients. Recurrent endoscopy is a significant burden for the healthcare system of the endoscopic unit as well as uncomfortable and high costs for patients. This study intended to prognosticate Right Liver Lobe Diameter/Serum Albumin Ratio (RLLD/Alb) as a non-invasive approach in the early diagnosis of EV among chronic liver disease (CLD) Bangladeshi patients enrolled in a specific hospital. PARTICIPANTS AND METHODS A total of 150 admitted patients with CLD were included in the study. Patients were subjected through a comprehensive biochemical checkup and upper digestive endoscopic or ultrasonographic inspection. The correlation was evaluated between the RLLD/Alb ratio and esophageal varices grades. RESULTS The upper digestive endoscopy demonstration among 150 patients resulted in no EV in 18%, while 24% of patients was identified as EV grade I, 20% as grade II, 20% as grade III, and 18% patients as grade IV. The mean value of the RLLD/Alb ratio was 4.89 ± 1.49 (range from 2.30 to 8.45). The RLLD/Alb ratio diagnosed the EV employing the cut-off value of 4.01 with 85.3% sensitivity and 68.8% specificity. Furthermore, it was positively correlated with the grading of EV, when this ratio increased the grading of EV increases and vice versa (r = 0.630, p < 0.001). CONCLUSION The RLLD/Alb ratio is a non-invasive parameter giving exact guidance relevant to the ascertainment of the existence of EV and their grading in chronic liver disease patients.

Abstract
Esophageal bleeding is a common complication in patients with liver cirrhosis. In thee present study, our aim was to divulge major factors predicting esophageal bleeding in Iranian children with liver cirrhosis. This was a cross-sectional study including 101 children < 18 years old referred to the Pediatric Endoscopy Unit of Nemazee Teaching Hospital of Shiraz from 2014 until 2016. Children with esophageal varices were included. The patients were divided into two groups including those with and without history of esophageal bleeding. Statistical methods were performed in SPSS 16 software. There were 49 boys and 52 girls. The mean age was 7.74±5.26 years old. A history of esophageal bleeding was observed in 53 (52.4%). In univariate analyses, significant relationships were found between esophageal bleeding and varices size (P=0.001), Child-Pugh score (P=0.01), age of bleeding initiation (P<0.001), serum creatinine (P=0.01), and serum sodium (P=0.002). There was no statistically significant difference in the mean of PELD/MELD score among children with (12.34±12) and without (14.61±17.51) history of esophageal bleeding (P=0.5). Among various etiologies of cirrhosis, a significant association was observed between autoimmune hepatitis and the history of esophageal bleeding (P=0.01). Regarding the clinical importance of esophageal bleedings in children with liver cirrhosis, it is recommended to further divulge the risk factors pre-disposing to this event.

Abstract
To expand on the work of previous meetings, a virtual Baveno VII workshop was organised for October 2021. Among patients with compensated cirrhosis or compensated advanced chronic liver disease (cACLD - defined at the Baveno VI conference), the presence or absence of clinically significant portal hypertension (CSPH) is associated with differing outcomes, including risk of death, and different diagnostic and therapeutic needs. Accordingly, the Baveno VII workshop was entitled "Personalized Care for Portal Hypertension". The main fields of discussion were the relevance and indications for measuring the hepatic venous pressure gradient as a gold standard, the use of non-invasive tools for the diagnosis of cACLD and CSPH, the impact of aetiological and non-aetiological therapies on the course of cirrhosis, the prevention of the first episode of decompensation, the management of an acute bleeding episode, the prevention of further decompensation, as well as the diagnosis and management of splanchnic vein thrombosis and other vascular disorders of the liver. For each of these 9 topics, a thorough review of the medical literature was performed, and a series of consensus statements/recommendations were discussed and agreed upon. A summary of the most important conclusions/recommendations derived from the workshop is reported here. The statements are classified as unchanged, changed, and new in relation to Baveno VI.

Abstract
Patients with cirrhosis and esophageal varices bleed at a yearly rate of 5%-15%, and, when variceal hemorrhage develops, mortality reaches 20%. Patients are deemed at high risk of bleeding when they present with medium or large-sized varices, when they have red signs on varices of any size and when they are classified as Child-Pugh C and have varices of any size. In order to avoid variceal bleeding and death, individuals with cirrhosis at high risk of bleeding must undergo primary prophylaxis, for which currently recommended strategies are the use of traditional non-selective beta-blockers (NSBBs) (i.e., propranolol or nadolol), carvedilol (a NSBB with additional alpha-adrenergic blocking effect) or endoscopic variceal ligation (EVL). The superiority of one of these alternatives over the others is controversial. While EVL might be superior to pharmacological therapy regarding the prevention of the first bleeding episode, either traditional NSBBs or carvedilol seem to play a more prominent role in mortality reduction, probably due to their capacity of preventing other complications of cirrhosis through the decrease in portal hypertension. A sequential strategy, in which patients unresponsive to pharmacological therapy would be submitted to endoscopic treatment, or the combination of pharmacological and endoscopic strategies might be beneficial and deserve further investigation.

CT hepatic arterial perfusion index does not allow stratification of the degree of esophageal varices and bleeding risk in cirrhotic patients in Child-Pugh classes A and B. Abdom Radiol (NY) 2021; 46:5586-5597. [PMID: 34453180 PMCID: PMC8590679 DOI: 10.1007/s00261-021-03259-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2021] [Revised: 08/18/2021] [Accepted: 08/19/2021] [Indexed: 11/17/2022]
Abstract
Purpose To evaluate if the hepatic arterial perfusion index (HPI) in liver parenchyma of cirrhotic patients can serve as a surrogate parameter for stratifying the degree of esophageal varices and related bleeding risks. Methods CT image data of sixty-six patients (59 men; mean age 68 years ± 10 years) with liver cirrhosis (Child–Pugh class A (35/66, 53%), B (25/66, 38%), and C (6/66, 9%) who underwent perfusion CT (PCT) for hepatocellular carcinoma (HCC) screening between April 2010 and January 2019 were retrospectively identified. HPI, a parameter calculated by a commercially available CT liver perfusion analysis software that is based on the double maximum slope model, using time attenuation curve to determine perfusion, was correlated with the degree of esophageal varices diagnosed at endoscopy and the number of bleeding events. Results Eta correlation coefficient for HPI/presence of esophageal varices was very weak (0.083). Spearman-Rho for HPI/grading of esophageal varices was very weak (0.037 (p = 0.804)). Kendall-Tau-b for HPI/grading of esophageal varices was very weak (0.027 (p = 0.807)). ANOVA and Bonferroni post-hoc-tests showed no significant difference of HPI between different grades of esophageal varices (F (3, 62) = 1.676, p = 0.186). Eta correlation coefficient for HPI/bleeding event was very weak (0.126). Conclusion The stratification of the degree of esophageal varices and the related bleeding risk by correlation with the HPI as a surrogate parameter for portal venous hypertension was not possible for patients with liver cirrhosis in Child–Pugh class A and B.

Abstract
INTRODUCTION AND OBJECTIVES We examined whether Mac-2-binding protein glycosylation isomer (M2BPGi) levels could be a predictive marker for the presence of esophagogastric varices (EGV) in cirrhotic patients after hepatitis C virus (HCV) eradication with direct-acting antivirals (DAAs). PATIENTS AND METHODS A total of 102 cirrhotic patients with HCV infection treated with DAAs were enrolled. Esophagogastroduodenoscopy was performed in 84 of the patients before treatment (Cohort A), in 66 after treatment (Cohort B), and in 48 at both time points (Cohort C). We examined factors associated with EGV before and after DAA treatment. RESULTS In Cohort A, M2BPGi levels and liver stiffness were significantly higher in the EGV-positive group than the EGV-negative group (p=0.034, and p=0.042, respectively). The proportion of EGV-positive patients with before-treatment levels of M2BPGi ≧ 7.3 C.O.I. was significantly higher than in patients with M2BPGi levels<7.3 C.O.I. (p=0.015). In Cohort B, M2BPGi levels were significantly higher in the EGV-positive group than EGV-negative group (p=0.003). The proportion of EGV-positive patients with after-treatment levels of M2BPGi ≧ 3.4 C.O.I. was significantly higher than in patients with M2BPGi levels<3.4C.O.I. (p=0.001). In Cohort C, M2BPGi levels decreased during DAA treatment regardless of EGV development, but there was no significant difference in the reduction of M2BPGi among the EGV-improvement, EGV-invariant, and EGV-exacerbation groups (p=0.659). CONCLUSIONS M2BPGi levels may be a novel serum marker for the presence of EGV before and after DAA treatment.

Abstract
BACKGROUND Recipient hepatectomy during liver transplantation can be a challenging operation and can increase cold ischaemic time. The aim of this study is to assess factors associated with prolonged recipient hepatectomy. METHODS From 2005 to 2015, 930 patients were submitted to liver transplantation in our hospital. Prolonged hepatectomy time was defined as operative time >180 min (from knife on skin to total hepatectomy). Patients undergoing early liver retransplantation and living donation were excluded. RESULTS A total of 715 patients were included in our study. Median age at transplantation was 53 (18-70) years, and median BMI was 26.2 (16-40). Median hepatectomy time was 131 min. Prolonged hepatectomy time occurred in 89 (12.4%) patients. At univariate analysis, previous decompensated cirrhosis with variceal bleeding and/or ascites, higher BMI and previous abdominal surgery were associated with prolonged operating time. Higher surgeon experience and acute liver failure were associated with shorter hepatectomy time. At multivariate analysis, previous episodes of variceal bleeding (p = 0.027, OR 1.78), BMI > 27 (p = 0.01, OR 1.75), previous abdominal surgery (p = 0.04, OR 1.68) and surgeon experience (p = 0.007, OR 2.04) were independently associated with operating time. Prolonged hepatectomy time was significantly associated with cold and total ischaemic time and intraoperative bleeding (p < 0.001, p = 0.002 and p = 0.002, respectively). CONCLUSIONS Recipient BMI, previous episodes of variceal bleeding, previous abdominal surgery and surgeon experience are independently associated with hepatectomy duration. These factors can be helpful to identify those patients with potentially prolonged hepatectomy time, and therefore, strategies can be put in place to optimize outcomes in this group of patients.

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

Caput medusae sign; a unique finding during abdominal examination in patients with portal hypertension; case report. Ann Med Surg (Lond) 2020; 54:54-56.

Abstract
Portal hypertension is an increase in the portal venous pressure resulting in the formation of dilated veins at the site of porto-systemic venous anastomosis causing shifting of the blood flow from the portal venous system to the systemic circulation. A 53-year-old male presented to the emergency department complaining from hematemesis. He was admitted to the emergency department. Abdominal examination showed hugely dilated veins in the abdominal wall with palpable spleen and liver. The hemoglobin level was low and liver enzymes were mildly elevated. The patient received two units of blood and four units of fresh frozen plasma, intravenous propranolol and intravenous vasopressin. Endoscopy showed variceal bleeding which was mild, multiple bandings were performed for the bleeding vessels. The past medical history was negative apart from idiopathic portal vein thrombosis. He was on regular anticoagulants and beta blockers. The patient was prepared to undergo surgical shunting procedure. Acute variceal bleeding is a medical emergency, and patients need aggressive form of treatment. Most drugs like beta-blockers, derivatives of vasopressin and somatostatins work by inducing splanchnic vasoconstriction and decrease the portal venous pressure. Endoscopic band ligation may be required but this has no effect on the portal venous pressure, other alternatives include trans-jugular intrahepatic portosystemic shunts or surgery. Caput medusae sign is a clinical sign indicating portal hypertension. It results from shifting of blood flow from the portal venous system to the systemic circulation. This results in the formation of dilated veins at the site of porto-systemic venous anastomosis. Portal hypertension results in splenomegaly, ascites, esophageal and gastric varices.

J Gastroenterol 2020; 55:877-887.

Abstract
BACKGROUND Although balloon-occluded retrograde transvenous obliteration (BRTO) is often selected to treat gastric varices caused by portal hypertension, data comparing BRTO and splenectomy with gastric devascularization (Sp + Dev) are limited. METHODS From January 2009 to February 2018, 100 patients with gastric varices caused by portal hypertension who underwent Sp + Dev (n = 45) or BRTO (n = 55) were included. Overall survival (OS) and the rebleeding rate were calculated using the inverse probability of a treatment weighting-adjusted log-rank test. Independent risk factors were identified by Cox regression analysis. Changes in liver function and adverse events after the procedures were analyzed. RESULTS Patients in the Sp + Dev group tended to have lower platelet counts than those in the BRTO group, but liver function did not differ between these groups. The 5-year OS rates for the Sp + Dev and BRTO groups were 73.4 and 50.0% (p = 0.005), respectively. There were no significant differences in rebleeding rates between the two groups. Multivariate analysis showed that serum albumin level ≤3.6 g/dL, prothrombin time% activity (PT%) ≤80%, and serum creatinine level ≥0.84 mg/dL were poor prognostic factors. Although the Sp + Dev group had more short-term complications after procedures, Sp + Dev tended to be more effective in improving liver function than BRTO. CONCLUSIONS Sp + Dev showed better OS and improvement of liver function compared with BRTO for the treatment of gastric varices caused by portal hypertension.

Performance of Baveno VI and Expanded Baveno VI Criteria for Excluding High-Risk Varices in Patients With Chronic Liver Diseases: A Systematic Review and Meta-analysis. Clin Gastroenterol Hepatol 2019; 17:1744-1755.e11.

Abstract
BACKGROUND & AIMS We aimed to assess the accuracy of Baveno VI criteria for identification of high-risk varices (HRVs) and varices of any size in patients with compensated advanced chronic liver disease (cACLD). METHODS We performed a systematic search of publications through December 2018 for studies that assessed the accuracy of Baveno VI criteria for screening for varices in patients with cACLD. We used hierarchical models to synthesize evidence. We also conducted a post hoc analysis to assess the accuracy of Εxpanded Baveno VI criteria. We appraised the confidence in estimates using the Grading of Recommendations Assessment, Development and Evaluation approach. RESULTS We identified 30 studies (8469 participants). Pooled values of Baveno VI criteria for HRVs (26 studies) were a sensitivity of 0.97 (95% CI, 0.95-0.98) and a specificity of 0.32 (95% CI, 0.26-0.39). Pooled sensitivity of Εxpanded Baveno VI criteria for HRVs (12 studies) was 0.90 (95% CI, 0.85-0.93) and specificity was 0.51 (95% CI, 0.45-0.57). In 1000 patients with cACLD, with a prevalence of HRVs of 20%, Baveno VI criteria would prevent endoscopy in 262 patients, but 6 patients with HRVs would be missed. Instead, use of the Εxpanded Baveno VI criteria would result in 428 patients avoiding endoscopy, but 20 patients with HRVs would be missed. The credibility of our findings is moderate or low, mainly owing to the retrospective design of most studies. CONCLUSIONS Baveno VI criteria have high diagnostic accuracy as a triage test for screening for HRVs in patients with cACLD. Expanded Baveno VI criteria could reduce the proportion of unnecessary endoscopies further, nevertheless with a higher rate of missed HRVs.

Transjugular intrahepatic portosystemic shunt for the prevention of recurrent esophageal variceal bleeding in patients with cavernous transformation of portal vein. Hepatobiliary Pancreat Dis Int 2018; 17:517-523.

Abstract
BACKGROUND Treatment options for patients with cavernous transformation of portal vein (CTPV) are limited. This study aimed to evaluate the feasibility, efficacy and safety of transjugular intrahepatic portosystemic shunt (TIPS) to prevent recurrent esophageal variceal bleeding in patients with CTPV. METHODS We retrospectively analyzed 67 consecutive patients undergone TIPS from January 2011 to December 2016. All patients were diagnosed with CTPV. The indication for TIPS was a previous episode of variceal bleeding. The data on recurrent bleeding, stent patency, hepatic encephalopathy and survival were retrieved and analyzed. RESULTS TIPS procedure was successfully performed in 56 out of 67 (83.6%) patients with CTPV. TIPS was performed via a transjugular approach alone (n = 15), a combined transjugular/transhepatic approach (n = 33) and a combined transjugular/transsplenic approach (n = 8). Mean portosystemic pressure gradient (PSG) decreased from 28.09 ± 7.28 mmHg to 17.53 ± 6.12 mmHg after TIPS (P < 0.01). The probability of the remaining free recurrent variceal bleeding was 87.0%. The probability of TIPS patency reached 81.5%. Hepatic encephalopathy occurrence was 27.8%, and survival rate was 88.9% until the end of follow-up. Four out of 11 patients who failed TIPS died, and 4 had recurrent bleeding. CONCLUSIONS TIPS should be considered a safe and feasible alternative therapy to prevent recurrent esophageal variceal bleeding in patients with CTPV, and to achieve clinical improvement.

Abstract
BACKGROUND & AIMS Pattern recognition receptors (PRRs) have a key role in the innate host defense. Functional polymorphisms of various PRRs have been established to contribute to an increased susceptibility to spontaneous bacterial peritonitis (SBP). Their role in the development of cirrhosis-associated bacterial infections (BI), beyond SBP or progressive disease course related to pathological bacterial translocation (BT) remains unknown. METHODS Three hundred and forty-nine patients with cirrhosis were genotyped for common NOD2 (R702W, G908R and L1007PfsinsC), TLR2 (-16934T>A), and TLR4 (D299G) variants. Incidence of BIs, decompensating events and liver-related death were assessed in a 5-year follow-up observational study. Pathological BT was assessed based on the presence of antimicrobial antibodies or lipopolysaccharide-binding protein (LBP) level. RESULTS In patients with ascites (n = 88) only NOD2 gene variants were associated with an increased cumulative probability of SBP (76.9% ± 19.9%) compared to wild-type (30.9% ± 6.9%, PLogRank = .047). Individual or combined PRR genetic profiles were associated with the risk of non-SBP type BI. Advanced disease stage (HR [95% CI]: 2.11 [1.38-3.25]) and prior history of a BI episode (HR: 2.42 [1.58-3.72]) were the major clinical risk factors of a subsequent BI. The risk of a non-SBP type BI in patients with advanced disease and a prior BI was even higher (HR: 4.74 [2.68-8.39]). The frequency of antimicrobial antibodies and LBP levels did not differ between various PRR genotypes. Correspondingly, PRR genetic profile was not able to predict the long-term disease course. CONCLUSIONS In cirrhosis, functional polymorphisms of PRRs did not improve the identification of patients with high risk of BI beyond SBP or progressive diseases course.

Abstract
Background The purpose of this study was to investigate splanchnic hemodynamic changes and determine an optimal cutoff value for risk factors of portal venous system thrombosis (PVST) after splenectomy with periesophagogastric devascularization (SPD) in cirrhotic patients with esophageal and gastric variceal bleeding (EGVB) and portal hypertension (PH). Material/Methods Data on patients who underwent SPD were collected retrospectively from January 2013 to December 2017. Color Doppler ultrasound was performed to detect hemodynamic changes of the hepatic artery, splenic artery, splenic vein, and portal vein in included patients (n=60) and healthy volunteers (n=30). Outcomes were compared between preoperative and postoperative biochemical indicators. The cutoff values for hemodynamics were identified using receiver operating characteristic (ROC) curve analysis, and univariate and multivariate analyses of risk factors of PVST were performed. Results In our series, hemodynamic indexes of splenic artery, spleen vein, and portal vein in the study group were significantly higher than that of the control group (P<0.05). Multivariate analysis revealed that the portal vein flow and the internal diameter of the portal vein were significantly correlated with PVST. The ROC analysis revealed that the cutoff points for portal vein flow and internal diameter of the splenic vein and portal vein were ≥1822.32 ml/min, ≥1.37 cm, and ≥1.56 cm, respectively. Conclusions SPD is an effective treatment in cirrhotic patients with concomitant EGVB and PH by increasing hepatic artery flow and decreasing portal vein flow. High portal vein flow and wider diameters of the portal vein and splenic vein are important markers of PVST.

Abstract
Non-invasive liver fibrosis assessment techniques are under development for evaluating the severity of liver disease and portal hypertension. The paper presents practical arrangements for the diagnosis and treatment of portal hypertension in patients with chronic liver disease, established in the Baveno VI Consensus Workshop for diagnosis and treatment of portal hypertension. Currently, the diagnostic standard of liver disease severity is transient elastography, which can identify patients with clinically significant portal hypertension (liver stiffness > 20 kPa). The paper presents the eligibility criteria for endoscopy and the principle of repeating the assessment of oesophageal varices. It also describes the primary and secondary prevention of gastroesophageal haemorrhage, the treatment of oesophageal bleeding and the treatment of liver vessel thrombosis.

Abstract
Esophageal varices are one of the main complications of liver cirrhosis. Upper gastrointestinal endoscopy is the gold standard for the detection of esophageal varices. Many less invasive methods for screening of varices have been investigated and the most recent Baveno VI guidelines suggest that endoscopy is not necessary in patients with liver stiffness <20 kPa and platelets >150,000/μL. A critical review of the literature was performed concerning non-invasive or minimally invasive methods of screening for esophageal varices. Liver and spleen elastography, imaging methods including computed tomography, magnetic resonance imaging and ultrasound, laboratory tests and capsule endoscopy are discussed. The accuracy of each method, and its advantages and limitations compared to endoscopy are analyzed. There are data to support the Baveno VI guidelines, but there is still a lack of large prospective studies and low specificity has been reported for the liver stiffness and platelet count combination. Spleen elastography has shown promising results, as there are data to support its superiority to liver elastography, but it needs further assessment. Computed tomography has shown high diagnostic accuracy and can be part of the diagnostic work up of cirrhotic patients in the future, including screening for varices.

Abstract
Introduction Noninvasive assessment of esophageal varices (EV) decreases the medical and financial burden related to screening and helps in the management of patients with chronic liver diseases (CLDs). In this study, our aim was to assess the utility of the platelet count/spleen diameter index for the noninvasive evaluation of EV. Materials and methods In this cross-sectional observational study, a total of 100 CLD patients underwent screening endoscopy for EV in Medicine and Gastroenterology Department, Sylhet MAG Osmani Medical College Hospital, Sylhet, Bangladesh. Platelet count/spleen diameter ratio was assessed in all patients and its diagnostic implication was calculated. Results Upper gastrointestinal endoscopy revealed that 45 (45.0%) patients had medium EV followed by 27 (27.0%) that had small EV and 19 (19.0%) patients had large EV. Receiver operator characteristic (ROC) curve was constructed using platelet count/spleen index, which gave a cut-off value of >905. The validity of platelet count/spleen index evaluation of CLD was: Sensitivity 92.3%, specificity 66.7%, accuracy 90.0%, positive predictive value (PPV) and negative predictive value (NPV) were 96.6 and 46.2% respectively. True positive was 84 cases, false positive 3 cases, false negative 7 cases, and true negative 6 cases. If we consider cut-off value as 909 in the evaluation of EV in CLD, then true positive was 85 cases, false positive 3 cases, false negative 6 cases, and true negative 6 cases. From this, by calculation, sensitivity was 93.4%, specificity 66.7%, accuracy 91%, PPV 96.6%, and NPV 50%. Conclusion The platelet count/spleen index may be proposed to be a safe and reliable mean of screening of EV in CLD patients; however, case-control study would be required to validate this.

Abstract
This document represents the first position statement produced by the British Society of Gastroenterology and Association of Upper Gastrointestinal Surgeons of Great Britain and Ireland, setting out the minimum expected standards in diagnostic upper gastrointestinal endoscopy. The need for this statement has arisen from the recognition that while technical competence can be rapidly acquired, in practice the performance of a high-quality examination is variable, with an unacceptably high rate of failure to diagnose cancer at endoscopy. The importance of detecting early neoplasia has taken on greater significance in this era of minimally invasive, organ-preserving endoscopic therapy. In this position statement we describe 38 recommendations to improve diagnostic endoscopy quality. Our goal is to emphasise practices that encourage mucosal inspection and lesion recognition, with the aim of optimising the early diagnosis of upper gastrointestinal disease and improving patient outcomes.

Abstract
BACKGROUND Esophageal variceal hemorrhage is a complication of cirrhosis that carries high mortality, and can be reduced with timely endoscopic variceal screening and treatment. AIM We aim to evaluate overall rates of and disparities in receipt of endoscopic variceal screening among an ethnically diverse urban safety-net hospital. METHODS All consecutive adults with cirrhosis (7/1/2014 to 12/31/2015) were retrospectively evaluated to determine the rates of receiving esophageal variceal screening within 6 months and within 1 year after cirrhosis diagnosis. Race-/ethnicity-specific differences in rates of variceal screening were compared using chi-square testing and multivariate regression methods. RESULTS Among 157 patients (65% male, 33.8% Hispanic, 22.3% African-American, 44.6% alcoholic liver disease, 29.9% chronic HCV), 56.8% received variceal screening within 6 months and 65.8% received screening within 1 year. Compared to non-Hispanic whites with cirrhosis, African-Americans (52.2 vs. 76.2%, p < 0.05), Asians (57.1 vs. 76.2%, p < 0.05), and Hispanics (43.9 vs. 76.2%, p < 0.05) were all significantly less likely to receive endoscopic variceal screening within 6 months after cirrhosis diagnosis. On multivariate analysis, African-Americans with cirrhosis were 66% less likely to receive variceal screening compared to non-Hispanic whites (HR 0.34, 95% CI 0.15-0.77, p < 0.01). CONCLUSION Among adults with cirrhosis at a community-based safety-net hospital system, overall first-time variceal screening remains suboptimal. African-Americans were the least likely to receive timely variceal screening. These findings are particularly concerning given the significant barriers that ethnic minorities and safety-net populations already face in timely access to medical care.

Abstract
BACKGROUND AND AIM Both balloon-occluded retrograde transvenous obliteration (BRTO) and transjugular intrahepatic portosystemic shunt (TIPS) are considered effective treatments for gastric variceal bleeding (GVB). In this study, outcomes of these two procedures were compared in managing patients with GVB. METHODS A total of 142 patients undergoing BRTO (n = 95) or TIPS (n = 47) between 2005 and 2012 at two tertiary centers were selected for retrospective review. RESULTS Mean patient age (male, 115; female, 27) was 58.1 years. Alcoholic liver cirrhosis was the most common underlying cause (n = 63, 44.4%), followed by hepatitis B (n = 60, 42.3%) and hepatitis C (n = 7, 4.9%) viral infections. Concurrent hepatocellular carcinoma (HCC) was identified in 64 (45.1%) patients. During the follow-up period (mean, 28.2 months), 27 patients (19%) experienced re-bleeding. Cumulative re-bleeding rates after BRTO (8.6% at 1 year; 22.7% at 3 years) were significantly lower than those after TIPS (19.8% at 1 year; 48.2% at 3 years; P = 0.006, log-rank test). In multivariate analysis, TIPS (vs BRTO) was found independently predictive of re-bleeding (hazard ratio [HR] = 2.174; P = 0.048), in addition to concurrent HCC and poor baseline Child-Pugh score (both P < 0.05). Although BRTO surpassed TIPS (P = 0.026, log-rank test) in terms of overall postprocedural survival, independent factors predictive of poor overall survival after hemostasis were concurrent HCC (HR = 3.106), high Child-Pugh score (HR = 1.886 per 1-point increase), and postprocedural hepatic encephalopathy (HR = 3.014; all P < 0.05). CONCLUSION Balloon-occluded retrograde transvenous obliteration proved more effective than TIPS in hemostasis of GVB, associated with significantly less risk of re-bleeding.

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

Abstract
Acute haemorrhage from ruptured gastroesophageal varices is perhaps the most serious consequence of uncontrolled portal hypertension in cirrhotic patients. It represents a medical emergency and is associated with a high morbidity and mortality. In those who survive the initial bleeding event, the risks of further bleeding and other decompensated events remain high. The past 30 years have seen a slow evolution of management strategies that have greatly improved the chances of surviving a variceal haemorrhage. Liver cirrhosis is a multi-staged pathological process and we are moving away from a one-size-fits-all therapeutic approach. Instead there is an increasing recognition that a more nuanced approach will yield optimal survival for patients. This approach seeks to risk stratify patients according to their disease stage. The exact type and timing of treatment offered can then be varied to suit individual patients. At the same time, the toolbox of available therapy is expanding and there is a continual stream of emerging evidence to support the use of endoscopic and pharmacological therapies. In this review, we present a summary of the treatment options for a variety of different clinical scenarios and for when there is failure to control bleeding. We have conducted a detailed literature review and presented up-to-date evidence from either primary randomized-controlled trials or meta-analyses that support current treatment algorithms.

Abstract
BACKGROUND Current guidelines recommend screening of people with oesophageal varices via oesophago-gastro-duodenoscopy at the time of diagnosis of hepatic cirrhosis. This requires that people repeatedly undergo unpleasant invasive procedures with their attendant risks, although half of these people have no identifiable oesophageal varices 10 years after the initial diagnosis of cirrhosis. Platelet count, spleen length, and platelet count-to-spleen length ratio are non-invasive tests proposed as triage tests for the diagnosis of oesophageal varices. OBJECTIVES Primary objectives To determine the diagnostic accuracy of platelet count, spleen length, and platelet count-to-spleen length ratio for the diagnosis of oesophageal varices of any size in paediatric or adult patients with chronic liver disease or portal vein thrombosis, irrespective of aetiology. To investigate the accuracy of these non-invasive tests as triage or replacement of oesophago-gastro-duodenoscopy. Secondary objectives To compare the diagnostic accuracy of these same tests for the diagnosis of high-risk oesophageal varices in paediatric or adult patients with chronic liver disease or portal vein thrombosis, irrespective of aetiology.We aimed to perform pair-wise comparisons between the three index tests, while considering predefined cut-off values.We investigated sources of heterogeneity. SEARCH METHODS The Cochrane Hepato-Biliary Group Controlled Trials Register, the Cochrane Hepato-Biliary Group Diagnostic Test Accuracy Studies Register, the Cochrane Library, MEDLINE (OvidSP), Embase (OvidSP), and Science Citation Index - Expanded (Web of Science) (14 June 2016). We applied no language or document-type restrictions. SELECTION CRITERIA Studies evaluating the diagnostic accuracy of platelet count, spleen length, and platelet count-to-spleen length ratio for the diagnosis of oesophageal varices via oesophago-gastro-duodenoscopy as the reference standard in children or adults of any age with chronic liver disease or portal vein thrombosis, who did not have variceal bleeding. DATA COLLECTION AND ANALYSIS Standard Cochrane methods as outlined in the Cochrane Handbook for Diagnostic Test of Accuracy Reviews. MAIN RESULTS We included 71 studies, 67 of which enrolled only adults and four only children. All included studies were cross-sectional and were undertaken at a tertiary care centre. Eight studies reported study results in abstracts or letters. We considered all but one of the included studies to be at high risk of bias. We had major concerns about defining the cut-off value for the three index tests; most included studies derived the best cut-off values a posteriori, thus overestimating accuracy; 16 studies were designed to validate the 909 (n/mm3)/mm cut-off value for platelet count-to-spleen length ratio. Enrolment of participants was not consecutive in six studies and was unclear in 31 studies. Thirty-four studies assessed enrolment consecutively. Eleven studies excluded some included participants from the analyses, and in only one study, the time interval between index tests and the reference standard was longer than three months. Diagnosis of varices of any size. Platelet count showed sensitivity of 0.71 (95% confidence interval (CI) 0.63 to 0.77) and specificity of 0.80 (95% CI 0.69 to 0.88) (cut-off value of around 150,000/mm3 from 140,000 to 150,000/mm3; 10 studies, 2054 participants). When examining potential sources of heterogeneity, we found that of all predefined factors, only aetiology had a role: studies including participants with chronic hepatitis C reported different results when compared with studies including participants with mixed aetiologies (P = 0.036). Spleen length showed sensitivity of 0.85 (95% CI 0.75 to 0.91) and specificity of 0.54 (95% CI 0.46 to 0.62) (cut-off values of around 110 mm, from 110 to 112.5 mm; 13 studies, 1489 participants). Summary estimates for detection of varices of any size showed sensitivity of 0.93 (95% CI 0.83 to 0.97) and specificity of 0.84 (95% CI 0.75 to 0.91) in 17 studies, and 2637 participants had a cut-off value for platelet count-to-spleen length ratio of 909 (n/mm3)/mm. We found no effect of predefined sources of heterogeneity. An overall indirect comparison of the HSROCs of the three index tests showed that platelet count-to-spleen length ratio was the most accurate index test when compared with platelet count (P < 0.001) and spleen length (P < 0.001). Diagnosis of varices at high risk of bleeding. Platelet count showed sensitivity of 0.80 (95% CI 0.73 to 0.85) and specificity of 0.68 (95% CI 0.57 to 0.77) (cut-off value of around 150,000/mm3 from 140,000 to 160,000/mm3; seven studies, 1671 participants). For spleen length, we obtained only a summary ROC curve as we found no common cut-off between studies (six studies, 883 participants). Platelet count-to-spleen length ratio showed sensitivity of 0.85 (95% CI 0.72 to 0.93) and specificity of 0.66 (95% CI 0.52 to 0.77) (cut-off value of around 909 (n/mm3)/mm; from 897 to 921 (n/mm3)/mm; seven studies, 642 participants). An overall indirect comparison of the HSROCs of the three index tests showed that platelet count-to-spleen length ratio was the most accurate index test when compared with platelet count (P = 0.003) and spleen length (P < 0.001). DIagnosis of varices of any size in children. We found four studies including 277 children with different liver diseases and or portal vein thrombosis. Platelet count showed sensitivity of 0.71 (95% CI 0.60 to 0.80) and specificity of 0.83 (95% CI 0.70 to 0.91) (cut-off value of around 115,000/mm3; four studies, 277 participants). Platelet count-to-spleen length z-score ratio showed sensitivity of 0.74 (95% CI 0.65 to 0.81) and specificity of 0.64 (95% CI 0.36 to 0.84) (cut-off value of 25; two studies, 197 participants). AUTHORS' CONCLUSIONS Platelet count-to-spleen length ratio could be used to stratify the risk of oesophageal varices. This test can be used as a triage test before endoscopy, thus ruling out adults without varices. In the case of a ratio > 909 (n/mm3)/mm, the presence of oesophageal varices of any size can be excluded and only 7% of adults with varices of any size would be missed, allowing investigators to spare the number of oesophago-gastro-duodenoscopy examinations. This test is not accurate enough for identification of oesophageal varices at high risk of bleeding that require primary prophylaxis. Future studies should assess the diagnostic accuracy of this test in specific subgroups of patients, as well as its ability to predict variceal bleeding. New non-invasive tests should be examined.

Abstract
BACKGROUND Transjugular intrahepatic portosystemic shunt (TIPS) and open splenectomy and esophagogastric devascularization (OSED) are widely used to treat patients with portal hypertension and recurrent variceal bleeding (PHRVB). This study aimed to compare the effectiveness between TIPS and OSED for the treatment of PHRVB. METHODS The data were retrospectively retrieved from 479 cirrhotic patients (Child-Pugh A or B class) with PHRVB, who had undergone TIPS (TIPS group) or OSED (OSED group) between January 1, 2010 and October 31, 2014. RESULTS A total of 196 patients received TIPS, whereas 283 underwent OSED. Within one month after TIPS and OSED, the rebleeding rates were 6.1% and 3.2%, respectively (P=0.122). Significantly lower incidence of pleural effusion, splenic vein thrombosis, and pulmonary infection, as well as higher hepatic encephalopathy rate, shorter postoperative length of hospital stay, and higher hospital costs were observed in the TIPS group than those in the OSED group. During the follow-up periods (29 months), significantly higher incidences of rebleeding (15.3% vs 4.6%, P=0.001) and hepatic encephalopathy (17.3% vs 3.9%, P=0.001) were observed in the TIPS group than in the OSED group. The incidence of in-stent stenosis was 18.9%. The survival rates were 91.3% in the TIPS group and 95.1% in the OSED group. The long-term liver function did not worsen after either TIPS or OSED. CONCLUSION For the patients with liver function in the Child-Pugh A or B class, TIPS is not superior over OSED in terms of PHRVB treatment and rebleeding prevention.

Macrophage activation marker, soluble CD163, is an independent predictor of short-term mortality in patients with cirrhosis and bacterial infection. Liver Int 2016; 36:1628-1638.

Abstract
BACKGROUND & AIMS Innate immune system dysfunction is common in advanced cirrhosis, with a central role of the monocyte/macrophage system. Monocytes and macrophages express the scavenger receptor CD163, which is regulated by inflammatory mediators. Cleavage of the receptor leads to the formation of soluble (s)CD163 that represents an anti-inflammatory response. We aimed to study the clinical importance of sCD163 in cirrhosis. METHODS Sera of 378 patients were assayed for sCD163 by ELISA [193 outpatients and 185 patients with acute decompensation (AD)]. A 5-year follow-up observational study was conducted to assess the possible association between sCD163 level and poor disease outcomes. RESULTS sCD163 level was associated with disease severity, but not with the presence of varices or prior variceal bleeding. In outpatients, sCD163 level did not predict the development of disease-specific complications or the long-term mortality. In patients with AD episode, sCD163 level was significantly higher compared to outpatients but only in the presence of bacterial infection (INF) (AD-INF:4586, AD-NON-INF:3792 and outpatients: 3538 ng/ml, P < 0.015 and P = 0.001, respectively). sCD163 level gradually increased according to severity of infection. During bacterial infections, high sCD163 level (>7000 ng/ml) was associated with increased mortality rate (42% vs. 17%, P < 0.001) and was identified as an independent predictor of 28-day mortality (hazard ratio:2.96, 95% confidence intervals:1.27-6.95) in multivariate Cox-regression model comprising aetiology, co-morbidity, model for end-stage liver disease score and leucocyte count as covariates. CONCLUSIONS High sCD163 level is useful to identify patients with high-risk of death during an AD episode complicated by bacterial infection. This finding serves as an additional hint towards the significance of anti-inflammatory response during bacterial infection.

Abstract
The key to management of alcoholic liver disease (ALD) is early recognition by the patient and physician. Excessive alcohol consumption, ranging from drinking more than recommended amounts to abuse, is one of the most preventable causes of death and disability. The US Preventive Services Task Force guidelines recommend screening for alcoholism in the primary care setting. Abstinence is the cornerstone of therapy and it decreases mortality and morbidity significantly. Alcoholic cirrhosis can cause varices that need to be followed closely with upper endoscopy to prevent or treat hemorrhage. In this review, we describe an approach to long-term management of ALD.

Abstract
AIM To evaluate the value of D-dimer and P-selectin in cirrhotic portal hypertension (PHT) patients for prediction of portal vein thrombosis (PVT) after devascularization. MATERIAL AND METHODS 137 patients with cirrhotic PHT who undergone devascularization from January 2012 to April 2014 were retrospectively reviewed, all of them were divided into two groups (PVT group and non-PVT group) by Doppler ultrasonography (DU) examination. The level of D-dimer and P-selectin was tested during the peri-operative period. RESULTS 38 patients (27.7%) were found PVT by DU examination post-operatively. In contrast to the non- PVT group, the level of D-dimer and P-selectin in the PVT group was much higher significantly at 1, 3 and 7 days after devascularization (P < 0.05). However, in the 15 days after surgery, the difference of P-selectin between the two groups was not significant (P = 0.260). It was shown that the higher sensitivity of the two markers for PVT was D-dimer, the higher specificity belonged to P-selectin. The area under receiver operating characteristic (ROC) curve of P-selectin was the bigger of the two markers. When the two markers were combined to be used to diagnose PVT, the sensitivity was increased to 0.911, with a slight drop of specificity to 0.715, the area under ROC curve was 0.919. CONCLUSION The level of D-dimer and P-selectin might be good candidate predictive markers for PVT in patients with cirrhotic PHT after devascularization. The combined test of the two markers can increase the value of prediction.

Abstract
AIM To examine the platelet count (PC)/spleen diameter (SD) ratio in predicting the presence of esophageal varices (EV) in patients with schistosomiasis liver cirrhosis. MATERIALS AND METHODS A total of 95 consecutive patients with EV induced by schistosomiasis liver cirrhosis were enrolled in this trial. A total of 141 schistosomiasis liver cirrhosis patients without EV were enrolled as controls. All patients were diagnosed by endoscopy. Demographic, laboratory, and Doppler ultrasound parameters were collected and analyzed. Binary logistic regression analysis was carried out to identify independent risk factors associated with EV occurrence. Receiver operating curves were generated to obtain the PC/SD ratio cutoff values for the optimal sensitivity and specificity with respect to EV. RESULTS The accuracy was increased in diagnosing for EV using the ratio of PC/SD compared with the SD alone [area under the curve: 0.891 95% confidence interval (CI): 0.844-0.928 vs. 0.764 95% CI: 0.705-0.817; P<0.01]. The optimal cutoff value was 1004, with a 77.1% (95% CI: 67.9-84.8%) positive-predictive value and an 89.3% (95% CI: 82.7-94.0%) negative-predictive value. Using a cutoff of 1004, it was determined that 117/141 (83.0%) patients without EV could avoid undergoing unnecessary endoscopy, whereas 14/95 (14.7%) patients with EV would be misdiagnosed. In contrast, when the ratio was set at 909, the positive-predictive and negative-predictive values were 79.5% (95% CI: 69.5-87.4%) and 83.1% (95% CI: 76.1-88.8%), respectively. A ratio of 909 would accurately predict the absence of EV in 123/141 (87.2%) patients; however, 24/95 (25.3%) patients with EV would miss the necessary screening endoscopy. CONCLUSION The ratio of PC/SD was a useful marker in predicting the presence of EV in patients with schistosomiasis liver cirrhosis.

Abstract
Background and Objectives: Given the technical difficulty of laparoscopic splenectomy and azygoportal disconnection (LSD), data are limited that compare the laparoscopic to the open procedure. As the technique becomes more widespread, questions regarding its safety, feasibility, and reproducibility must be addressed. This review assesses the current status of LSD. Methods: We conducted our literature review with a search of the PubMed database. All published series of 5 or more laparoscopic splenectomy and azygoportal disconnection procedures were examined. The demographic, intraoperative, and postoperative data analyzed included number of ports, conversion rate, operative duration, estimated intraoperative blood loss, postoperative hospital stay, and complications. Results: Fifteen articles met the review criteria. Of 412 laparoscopic procedures, traditional laparoscopic splenectomy and azygoportal disconnection (TLSD) was used in 322 patients (78.2%), a modified laparoscopic procedure (MLSD) in 79 (19.2%), and a single-incision laparoscopic procedure (SLSD) in 11 (2.7%). Compared with the traditional and single-incision laparoscopic procedures, the MLSD procedure was associated with shorter operative duration and less blood loss. Furthermore, although the incidence of postoperative portal vein system thrombosis was higher in the laparoscopic than in the open splenectomy with azygoportal disconnection (OSD) procedure, the LSD procedure was associated with less pulmonary infection and pleural effusion and fewer incisional and overall complications than the open procedure. The rate of conversion to an open procedure was 5.4%. Conclusions: LSD is feasible and safe for selected patients when performed by an expert laparoscopic surgeon. It has perioperative advantages over OSD, but studies with longer follow-up periods and larger samples of patients are needed.

Abstract
Endoscopic variceal band ligation (EVL) is an effective procedure to control and prevent variceal bleeding in patients with liver cirrhosis, but it can be complicated by bleeding from post-EVL ulcers. Several studies have reported that proton pump inhibitors (PPIs) decrease the size of post-EVL ulcers. However, evidence are limited as to whether PPIs actually reduce the risk of bleeding after EVL. This study aimed to analyze the factors associated with bleeding after prophylactic EVL and to assess the effect of PPI therapy.Five hundred and five cirrhotic patients with high risk esophageal varices who received primary prophylactic EVL were included for this retrospective cohort study. Post-EVL bleeding was defined as bleeding after prophylactic EVL within 8 weeks evidenced by the occurrence of melena or hematemesis, or by a decrease of hemoglobin by >2.0 g/dL. If evidence of bleeding from ulceration of the EVL sites was confirmed by endoscopy, we defined it as post-EVL ulcer bleeding.Fourteen patients developed bleeding after prophylactic EVL. Factors associated with post-EVL bleeding included alcohol as etiology, low albumin, high total bilirubin, high Child-Pugh score, high MELD score, coexistence of gastric varices, and not administrating PPI medication by univariate analysis. In multivariate logistic analysis, Co-existing gastric varix (odds ratio [OR] 5.680, P = 0.005] and not administrating PPIs (OR 8.217, P = 0.002) were associated with bleeding after prophylactic EVL. In the subgroup analysis excluding patients whose gastric varices were treated, not administering PPI medication (OR 8.827, P = 0.008) was the sole factor associated with post-EVL bleeding.We suggest that PPI therapy needs to be considered in patients receiving prophylactic EVL to reduce the risk of bleeding after prophylactic EVL.

The long-term benefits of nucleos(t)ide analogs in compensated HBV cirrhotic patients with no or small esophageal varices: A 12-year prospective cohort study. J Hepatol 2015; 63:1118-25. [PMID: 26100495 DOI: 10.1016/j.jhep.2015.06.006] [Citation(s) in RCA: 63] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/22/2014] [Revised: 05/14/2015] [Accepted: 06/08/2015] [Indexed: 12/16/2022]
Abstract
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.

[PMID: 26299413 DOI: 10.1053/j.gastro.2015.07.067] [Citation(s) in RCA: 93] [Impact Index Per Article: 10.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/22/2015] [Revised: 06/29/2015] [Accepted: 07/17/2015] [Indexed: 12/13/2022]
Abstract
BACKGROUND & AIMS Minimal hepatic encephalopathy (MHE) is associated with falls, traffic accidents, and overt HE. However, the association with survival is controversial. We assessed the effects of MHE on the long-term survival of patients with cirrhosis. METHODS We performed a prospective study of 117 consecutive patients with cirrhosis seen at a tertiary hospital in Seville, Spain (estimation cohort), followed by a validation study of 114 consecutive patients with cirrhosis seen at 4 hospitals in Spain from January 2004 through December 2007. Patients were examined every 6 months at outpatient clinics through December 2013 (follow-up periods of 5 ± 2.8 y and 4.4 ± 3.9 y for each group, respectively). Cirrhosis was identified by liver biopsy, ultrasound, endoscopic analysis, and biochemical parameters. Liver dysfunction was determined based on model for end-stage liver disease (MELD) and Child-Pugh scores. All patients were administered the critical flicker frequency (CFF) test and psychometric hepatic encephalopathy scores were used to detect MHE. Survival curves were compared using the log-rank test and multivariable analysis was performed using Cox proportional hazards models. RESULTS The distributions of Child-Pugh scores were as follows: 66% class A, 31% class B, and 3% class C in the estimation cohort, and 50% class A, 32% class B, and 18% class C in the validation cohort. In the estimation cohort, 24 of 35 patients (68.6%) with a CFF score less than 39 Hz survived for 5 years, whereas 50 of 61 patients (82%) with a CFF score of 39 Hz or higher survived during the follow-up period (log-rank score, 5.07; P = .024). Psychometric hepatic encephalopathy scores did not correlate with survival. In multivariable analysis, older age (hazard ratio [HR], 1.07; 95% confidence interval [CI], 1.02-1.12; P = .009), CFF score less than 39 Hz (HR, 4.36; 95% CI, 1.67-11.37; P = .003), and MELD score (HR, 1.40; 95% CI, 1.21-1.63; P = .0001) were associated independently with survival during the follow-up period. In the validation cohort, CFF score less than 39 Hz and MELD score also were associated with patient survival during the follow-up period. MHE had no effect on the survival of patients with MELD scores less than 10 (among patients with CFF scores ≥39 Hz, 94.5% survived for 5 years vs 91.9% of patients with CFF scores <39 Hz; log-rank score, 0.64; P = .423). Fewer patients with MELD scores of 10-15 and MHE survived for 5 years (44.4%; 12 of 27) than those with MELD scores greater than 15 without MHE (61.5%; 8 of 13) (P < .05). Only 2 of 12 patients (16.7%) with MELD scores of 15 or higher and MHE survived for 5 years (log-rank score, 90.56; P = .0001). CONCLUSIONS MHE is associated with a reduced 5-year survival rate of patients with cirrhosis. Evaluation of MHE could help predict survival times and outcomes of patients with specific MELD scores. The CFF could help physicians determine prognoses of patients with cirrhosis.

Abstract
OBJECTIVE Our research was conducted to analyze the outcomes of two laparoscopic splenectomy plus pericardial devascularization (LSPD) techniques in the management of portal hypertension (PTH) and hypersplenism. METHODS Between May 2012 and May 2013, 41 patients with PTH and hypersplenism undergoing LSPD were retrospectively analyzed. Of them, 29 patients received LSPD by LigaSure Vessel Sealing System (LVSS) and Endo-GIA universal endoscopic vascular linear staplers (Endo-GIA) (EG Group) and 12 patients received LSPD by LVSS and Hem-o-Lock (HL Group). Operating time, intraoperative blood loss, postoperative course, and hospitalization costs were compared between the two LSPD combination techniques. RESULTS There were no significant differences in preoperative patient characteristics of the two groups. Significantly less operating time, intraoperative blood loss, and postoperative complications were observed in EG Group. The incidence of portal vein thrombosis was lower in the EG Group (3.4 vs. 8.3%), as well as the incidence of pancreatic fistula (0 vs. 8.3%). Upper gastrointestinal hemorrhage was not observed in either group. Uncontrolled bleeding warranted conversion to open surgery in one case in EG Group (conversion rate 3.4%) and in two cases in HL Group (conversion rate 16.7%). Two patients (16.7%) in HL Group underwent successful emergency exploratory laparotomy due to uncontrolled intraabdominal bleeding postoperatively. No re-operation was needed in EG Group. Two patients experienced liver failure after surgery in each group. Of those, three patients were managed successfully and one patient refused further therapy. While the overall complication rate was significantly lower in EG Group (17.2 vs. 58.3%, P < 0.05), overall hospitalization costs remained significantly higher for EG Group. CONCLUSION The results suggest that the modified Endo-GIA and LVSS technique is a safe and effective combination approach to LSPD with shorter operative time, less intraoperative blood loss, lower conversion rate to laparotomy, shorter hospital stay, better recovery, and lower postoperative complication rate compared with the Hem-o-Lock and LVSS approach. Higher hospitalization expenses associated with the Endo-GIA and LVSS approach.

Abstract
AIM To measure in vitro diameter of imitational varices using a self-made endoscopic scale and confirm its accuracy and clinical feasibility. METHODS A catheter was introduced into the endoscope accessory channel and attached to a zebra wire guide that was used as a stylet. The wire guide was fixed onto the tip of the catheter by a soft and thin string. By gently advancing the stylet into the catheter, the width of the opening loop at the tip of the endoscope approximated the diameter of the imitational varices. Measurements performed in vitro using this self-made endoscopic ruler were compared to measurements of simulative varices. RESULTS At the handle, the sleeve moving distance ranged from 5 to 14 mm. There was no obvious proportional relationship between the sleeve movement distance and endoscopic measurement ruler. The results indicated that the gap between the endoscopic measurement and actual measurement of the object size tended to close. The in vitro measurement of the diameter of the simulative varices showed that the two kinds of measuring methods were not significantly different with respect to their accuracy (P=0.8499). CONCLUSION In vitro experiments confirmed that using a self-designed endoscopic ruler to measure the diameter of simulative varices was objective, accurate and feasible.

Abstract
Introduction Portal hypertension results from increased resistance to portal blood flow and has the potential complications of variceal bleeding and ascites. The splenoportal veins increase in caliber with worsening portal hypertension, and partially decompress by opening a shunt with systemic circulation, ie, a varix. In the event of portosystemic shunting, there is a differential decompression across the portal vein and splenic vein (portal vein > splenic vein), with a resultant decrease in the ratio of portal vein diameter to that of splenic vein. Portal vein to splenic vein diameter ratio and gradient could be valuable tools in predicting the presence of portosystemic shunting. Methods We retrospectively reviewed patients with cirrhosis who underwent esophagogastroduodenoscopy (EGD) for variceal screening and had a computerized tomogram (CT) of the abdomen within 6 months of the index endoscopic study, between January 2009 and December 2013. Patients on nonselective beta blockers, patients with presinusoidal portal hypertension (portal vein thrombosis or extrinsic compression), and patients who had undergone portosystemic shunting procedures (transjugular intrahepatic portosystemic shunt [TIPS]) or balloon-occluded retrograde transvenous obliteration (BRTO) were excluded from the study. Splenic and portal vein diameters were measured (in mm) just proximal and distal to the splenomesenteric venous confluence, respectively. Results A total of 164 patients were included in the study; of these, 60% (n=98) were male and 40% (n=66) were female. The mean age of the study population was 58.7 years. A total of 126 patients (77%) had varices, while 38 patients (33%) did not. The mean Model for End-Stage Liver Disease (MELD) score was 5.9 for those who had varices as compared with 7.03 for those who did not. The mean of ratios of portal vein to splenic vein diameters in patients with varices was 1.27 (±0.2), while it was 1.5 (±0.23) in those without varices. This difference was statistically significant (P<0.001). The mean of the gradients between the portal vein and splenic vein diameters was 2.7 (±2) mm for patients with varices as compared with 5 (±1.8) mm in those without varices. This difference was also statistically different (P<0.001). These correlations were statistically significant even after controlling for age, sex, and MELD. These radiological indices also had statistically significant correlations with the presence of gastric varices (P=0.018 for the ratio and P=0.01 for the gradient). A discriminant function analysis was performed that generated the equation: D = 2.68 (ratio of portal vein to splenic vein diameters) + 0.187 (gradient of portal vein to splenic vein diameters, in mm) − 4.152. This equation had a very high sensitivity, of 95%, but low specificity, of 26.3%, in predicting the presence of esophageal varices. Conclusion Both venous diameter ratio (portal vein size/splenic vein size) and venous diameter gradient in mm (portal vein size – splenic vein size) calculated from CTs of the abdomen were good predictors of presence of esophageal varices. These parameters might be useful in stratifying patients at risk of developing esophageal varices who are poor candidates for endoscopic evaluation.

Abstract
Background/Aim: To evaluate the value of d-dimer, P-selectin, and platelet count in patients with cirrhotic portal hypertension (PHT) for prediction of portal vein thrombosis (PVT) after devascularization. Methods: A total of 137 patients with cirrhotic PHT who undergone devascularization from January 2012 to April 2014 were retrospectively reviewed, all of them were divided into 2 groups (PVT group and non-PVT group) by Doppler ultrasonography (DU) examination. The level of d-dimer, P-selectin, and platelet count was tested during the perioperative period. Results: In all, 38 (27.7%) patients were found to have PVT by DU examination postoperatively. In contrast to the non-PVT group, the level of d-dimer, P-selectin, and platelet count in the PVT group was much higher significantly at 1, 3, and 7 days after devascularization. ( P < .05). However, in the 15 days after surgery, the difference in P-selectin between the 2 groups was not significant ( P = .260). It was shown that the highest sensitivity of the 3 markers for PVT was d-dimer, the highest specificity belonged to P-selectin. The area under receiver–operating characteristic (ROC) curve of P-selectin was the biggest of the 3 markers. When the 3 markers were combined to be used to diagnose PVT, the sensitivity was increased to 0.907, with a slight drop of specificity to 0.693, the area under the ROC curve was 0.927. Conclusion: The level of d-dimer, P-selectin, and platelet count might be good candidate predictive markers for PVT in patients with cirrhotic PHT after devascularization. The combined test of the 3 markers can increase the value of prediction.

Abstract
BACKGROUND AND AIM Extrahepatic portal vein obstruction (EHPVO) is an important cause of portal hypertension in children. The aim of this study was to describe the clinical presentation, possible risk factors, upper gastrointestinal endoscopic findings, and treatment modalities of children with EHPVO. METHODS After ethical approval of our study protocol by our institution review board, we analyzed available data from medical records of patients with EHPVO presenting to the Pediatric Hepatology Unit, Cairo University Pediatric Hospital, Egypt, for a period of 15 years from January 1996 to December 2010. RESULTS The study included 169 patients. Their ages at presentation ranged from 1 month to 12 years (median 2.5 years, interquartile range 5); 101 were boys. Hematemesis was a presenting symptom in 58%, splenomegaly was present in 87%, esophageal varices were present in 94%, and fundal varices were present in 23%. Possible risk factors, in the form of umbilical catheterization, umbilical sepsis, and exchange transfusion, were elicited in 18%. Propranolol was associated with reduction in bleeding episodes (P < 0.001), but was associated with increased chest symptoms (P < 0.01). Both injection sclerotherapy and band ligation were effective in the management of bleeding varices and for primary and secondary prophylaxis; however, injection sclerotherapy was associated with the development of secondary gastric varices (P = 0.03). CONCLUSIONS This large study of children with EHPVO demonstrates the efficacy of propranolol in the reduction of gastrointestinal bleeding in children with EHPVO. Both injection sclerotherapy and band ligation were effective in the management of esophageal varices, although the former was associated with the development of secondary gastric varices. Randomized clinical trials to choose the best modalities for the management of portal hypertension in children are still lacking.

Abstract
BACKGROUND Abdominal ultrasound (US) may provide data on the presence of esophageal varices in cirrhosis. We assess the diagnostic accuracy of this procedure. PATIENTS AND METHODS Retrospective recording of clinical data was carried out in cirrhotic patients who underwent abdominal US and upper gastrointestinal endoscopy. We compared patients with and without large varices and assessed the value of US in predicting the presence of these lesions as well as other significant variables. RESULTS Of the 353 patients included, 123 (35%) had esophageal varices. The presence of US signs of portal hypertension independently predicted the existence of esophageal varices with a sensitivity of 87.9%, a specificity of 34.9%, a positive predictive value of 40.6%, and a negative predictive value of 85.1%, which could increase to 91.5% if the patient presented plasma albumin and platelet concentrations above the mean values (3.1 g/dl and 122×10 cells/l, respectively). Plasma albumin and platelet concentrations were the two other variables with independent predictive capacity. Applying these selection criteria, up to 30% of screening endoscopies may not be necessary, and up to 43% in patients with compensated cirrhosis. In patients with decompensated cirrhosis, however, US does not have predictive capacity. The results obtained are comparable with those reported for transient elastography. CONCLUSION Abdominal US is a highly reliable technique for detecting patients with a low risk of presenting esophageal varices. Its use may avoid up to 43% of screening endoscopies in patients with compensated cirrhosis. The results obtained are similar to those observed using transient elastography.

Abstract
BACKGROUND Current guidelines recommend performance of oesophago-gastro-duodenoscopy at the time of diagnosis of hepatic cirrhosis to screen for oesophageal varices. These guidelines require people to undergo an unpleasant invasive procedure repeatedly with its attendant risks, despite the fact that half of the people do not have identifiable oesophageal varices 10 years after the initial diagnosis of cirrhosis. Video capsule endoscopy is a non-invasive test proposed as an alternative method for the diagnosis of oesophageal varices. OBJECTIVES To determine the diagnostic accuracy of capsule endoscopy for the diagnosis of oesophageal varices in children or adults with chronic liver disease or portal vein thrombosis, irrespective of the aetiology. To investigate the accuracy of capsule endoscopy as triage or replacement of oesophago-gastro-duodenoscopy. SEARCH METHODS We searched the Cochrane Hepato-Biliary Group Diagnostic Test Accuracy Studies Register (October 2013), MEDLINE (Ovid SP) (1950 to October 2013), EMBASE (Ovid SP) (1980 to October 2013), ACP Journal Club (Ovid SP) (1991 to October 2013), Database of Abstracts of Reviews of Effects (DARE) (Ovid SP) (third quarter), Health Technology Assessment (HTA) (Ovid SP) (third quarter), NHS Economic Evaluation Database (NHSEED) (Ovid SP) (third quarter), and Science Citation Index Expanded (SCI-EXPANDED) (ISI Web of Knowledge) (1955 to October 2013). We applied no language or document type restrictions. SELECTION CRITERIA Studies that evaluated the diagnostic accuracy of capsule endoscopy for the diagnosis of oesophageal varices using oesophago-gastro-duodenoscopy as the reference standard in children or adults of any age, with chronic liver disease or portal vein thrombosis. DATA COLLECTION AND ANALYSIS We followed the available guidelines provided in the Cochrane Handbook for Diagnostic Test of Accuracy Reviews. We calculated the pooled estimates of sensitivity and specificity using the bivariate model due to the absence of a negative correlation in the receiver operating characteristic (ROC) space and of a threshold effect. MAIN RESULTS The search identified 16 eligible studies, in which only adults with cirrhosis were included. In one study, people with portal thrombosis were also included. We classified most of the studies at high risk of bias for the 'Participants selection' and the 'Flow and timing' domains. One study assessed the accuracy of capsule endoscopy for the diagnosis of large (high-risk) oesophageal varices. In the remaining15 studies that assessed the accuracy of capsule endoscopy for the diagnosis of oesophageal varices of any size in people with cirrhosis, 936 participants were included; the pooled estimate of sensitivity was 84.8% (95% confidence interval (CI) 77.3% to 90.2%) and of specificity 84.3% (95% CI 73.1% to 91.4%). Eight of these studies included people with suspected varices or people with already diagnosed or even treated varices, or both, introducing a selection bias. Seven studies including only people with suspected but unknown varices were at low risk of bias; the pooled estimate of sensitivity was 79.7% (95% CI 73.1% to 85.0%) and of specificity 86.1% (95% CI 64.5% to 95.5%). Six studies assessed the diagnostic accuracy of capsule endoscopy for the diagnosis of large oesophageal varices, associated with a higher risk of bleeding; the pooled sensitivity was 73.7% (95% CI 52.4% to 87.7%) and of specificity 90.5% (95% CI 84.1% to 94.4%). Two studies also evaluated the presence of red marks, which are another marker of high risk of bleeding; the estimates of sensitivity and specificity varied widely. Two studies obtained similar results with the use of a modified device as index test (string capsule). Due to the absence of data, we could not perform all planned subgroup analyses. Interobserver agreement in the interpretation of capsule endoscopy results and any adverse event attributable to capsule endoscopy were poorly assessed and reported. Only four studies evaluated the interobserver agreement in the interpretation of capsule endoscopy results: the concordance was moderate. The participants' preferences for capsule endoscopy or oesophago-gastro-duodenoscopy were reported differently but seemed in favour of capsule endoscopy in nine of 10 studies. In 10 studies, participants reported some minor discomfort on swallowing the capsule. Only one study identified other significant adverse events, including impaction of the capsule due to previously unidentified oesophageal strictures in two participants. No adverse events were reported as a consequence of the reference standard. AUTHORS' CONCLUSIONS We cannot support the use of capsule endoscopy as a triage test in adults with cirrhosis, administered before oesophago-gastro-duodenoscopy, despite the low incidence of adverse events and participant reports of being better tolerated. Thus, we cannot conclude that oesophago-gastro-duodenoscopy can be replaced by capsule endoscopy for the detection of oesophageal varices in adults with cirrhosis. We found no data assessing capsule endoscopy in children and in people with portal thrombosis.

Abstract
Variceal bleeding is one of the most feared complications in patients with liver cirrhosis. It continues to be a leading cause of death among patients with liver cirrhosis. Although its prognosis has improved over the last several decades, it still carries substantial mortality. Preventing variceal bleeding has been extensively studied and evaluated in several studies in the recent years and the comparison between the different modalities available to prevent variceal bleeding has been an area of discussion. Currently the two most widely used modalities to prevent variceal bleeding are pharmacologic (non-selective beta-blockers [NSBB]) and endoscopic (variceal band ligation [VBL]) which have replaced sclerotherapy in the recent years. In addition to NSBB and recent carvedilol, different other medications have been evaluated including isosorbide mononitrates, spironolactone and angiotensin blocking agents. Comparing the outcomes and adverse effects of these two modalities has been evaluated in different studies. Some studies have showed superiority of VBL until recently, when carvedilol has been included, however; overall mortality has been similar in most trials. Despite that, NSBB remain the first line treatment, as they are cheaper and relatively effective in preventing both esophageal and gastric bleeding. The following sections discuss the primary prevention of variceal bleeding with a focus on NSBB, carvedilol and VBL.

Abstract
AIM: To develop a safe, simple, noninvasive and affordable system to predict esophageal variceal bleeding (EVB) in decompensated cirrhosis patients.
METHODS: Four hundred and eighty-six patients with decompensated cirrhosis (238 males and 248 females), with a mean age of 63.1 ± 11.2 years, were admitted to Changshu Affiliated Hospital of Suzhou University between May 2008 and March 2011. Patients enrolled in this study underwent ultrasound-Doppler (US-Doppler) to assess left gastric vein (LGV) blood flow velocity (LGVV) and blood flow direction (LGVBFD), and were evaluated by the Model For End-Stage Liver Disease (MELD) scoring system. All patients received follow-up evaluations every three months. The resulting data were entered into a database after each time point collection.
RESULTS: Four hundred and sixteen patients completed follow-up evaluations for an average of 31.6 mo (range: 12 to 47 mo). Fifty-one (12.3%) patients experienced EVB. The change in the MELD score over three months (ΔMELD), LGVV and LGVBFD were independently associated with EVB occurrence. MELD-US-Doppler Index (MUI), a new index, was developed and calculated using the following logistic regression equation: MUI = Logit (P) = 1.667 (ΔMELD) + 2.096 (LGVV) - 3.245 (LGVBFD) - 1.697. The area under the receiver operating characteristic curve for prediction of EVB occurrence was significantly higher for the MUI [0.858 (95%CI: 0.774-0.920)] than for ΔMELD [0.734 (95%CI: 0.636-0.817); P < 0.05], LGVV [0.679 (95%CI: 0.578-0.769); P < 0.05] or LGVBFD [0.726 (95%CI: 0.627-0.810); P < 0.05] alone. When the MUI was set at 46, the index had high diagnostic accuracy (85.8%), with high specificity (80%) and sensitivity (87.27%).
CONCLUSION: The MUI, a noninvasive and affordable index, can predict EVB occurrence in decompensated cirrhotic patients and serve as an alternative when conventional endoscopic screening is declined.
