Use of non-invasive scales for detecting esophageal varices in paediatric patients with portal vein thrombosis. GASTROENTEROLOGIA Y HEPATOLOGIA 2024; 47:433-438. [PMID: 37562768 DOI: 10.1016/j.gastrohep.2023.08.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/10/2023] [Revised: 06/26/2023] [Accepted: 08/03/2023] [Indexed: 08/12/2023]
Abstract
INTRODUCTION Portal vein thrombosis (PVT) is the most frequent cause of portal hypertension in paediatric population. Baveno VI Consensus considers endoscopic variceal ligation as the second therapeutic option after meso-Rex bypass (surgical shunt). AIM Analyse the diagnostic profitability of non-invasive scales in order to predict the risk of oesophageal varices (OV) in children with PVT. MATERIAL AND METHODS Descriptive retrospective study where every upper gastrointestinal endoscopy (UGE) carried on patients <15 years old with non-cirrhotic PVT were included. There were divided according to the presence of OV and sex, cause, age, previous gastrointestinal bleeding or treatments, results of UGE and scales (Clinical Prediction Rule - CPR), Varices Prediction Rule - VPR), King's Variceal Prediction Score - K-VaPS) and Platelet count/Spleen diameter Ratio - PSR). Qualitative variables were expressed as absolute frequency and percentage, and quantitative variables as median and interquartile range. U Mann-Whitney and Hanley-McNeil tests were used for comparisons. RESULTS Forty-five UGE were analysed. 80% (n=36) presented OV: median of 3 (2-3) and 33.3% (n=12) required endoscopic variceal ligation. Statistical differences were demonstrated between both groups: CPR (142.39 [132.22-166.53] vs. 122.75 [115.24-133.15]; p=0.003), VPR (9.91 [9.36-11.75] vs. 5.6 [3.34-8.39]; p=0.001), K-VaPS (117.86 [99.66-126.58] vs. 99.64 [94.88-10.18]; p=0.019), PSR (2384.62 [1902.22-3201.63] vs. 1252.5 [579.6-2144.42]; p=0.05), with and area under the curve AUROC>75%, without statistical differences between scales. CONCLUSIONS In paediatric patients with non-cirrotic PVT non-invasive scales can be used as a tool to predict the presence of OV and raise the indication of UGE.

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
The aetiology of several liver diseases in children is age specific and many of these conditions have significant and potentially long-term clinical repercussions if not diagnosed early and managed in a timely fashion. We address 5 clinical scenarios that cover most of the diagnostic and therapeutic emergencies in children: infants with liver disease; acute liver failure; management of bleeding varices; liver-based metabolic disorders; and liver tumours and trauma. A wide spectrum of conditions that cause liver disease in infants may present as conjugated jaundice, which could be the only symptom of time-sensitive disorders - such as biliary atresia, metabolic disorders, infections, and haematological/alloimmune disorders - wherein algorithmic multistage testing is required for accurate diagnosis. In infantile cholestasis, algorithmic multistage tests are necessary for an accurate early diagnosis, while vitamin K, specific milk formulae and disease-specific medications are essential to avoid mortality and long-term morbidity. Management of paediatric acute liver failure requires co-ordination with a liver transplant centre, safe transport and detailed age-specific aetiological work-up - clinical stabilisation with appropriate supportive care is central to survival if transplantation is indicated. Gastrointestinal bleeding may present as the initial manifestation or during follow-up in patients with portal vein thrombosis or chronic liver disease and can be managed pharmacologically, or with endoscopic/radiological interventions. Liver-based inborn errors of metabolism may present as encephalopathy that needs to be recognised and treated early to avoid further neurological sequelae and death. Liver tumours and liver trauma are both rare occurrences in children and are best managed by a multidisciplinary team in a specialist centre.

Abstract
OBJECTIVES To use a large administrative database to determine the mortality, risk factors, and comorbidities of esophageal variceal bleeding in children. STUDY DESIGN Retrospective cohort study using Pediatric Health Information System data from 50 tertiary children's hospitals in the US. International Classification of Diseases (ICD) codes (FY 2020 ICD-10 update and revision 10 of ICD-9) from 2004 through 2019 identified children 18 years and younger with variceal bleeding and complications. Univariate analyses used the Student t -test for continuous variables (age) and the χ2 test for categorical variables (all others). A mixed-effects linear regression was performed for multiple variables. RESULTS There were 1902 patients who had 3399 encounters for esophageal variceal bleeding. The mortality rate for variceal bleeding was 7.3%, increasing to 8.8% by 6 weeks; any mortality during the study was 20.1%. Transfusion was required in 54.7% of encounters, and 42.6% were admitted to the intensive care unit. Variceal bleeding encounters were complicated by peptic ulcer disease (6.9%), bacteremia (11.4%), acute renal failure (5.1%), mechanical ventilation (18%), ascites (21.3%), and peritonitis (3.3%). Multivariable mixed-effects logistic regression showed that Black race (OR, 2.59; P < .001) or Hispanic ethnicity (OR, 2.31; P = .001), but not sex, household income, or insurance type, were associated with increased mortality. Bacteremia, peritonitis, mechanical ventilation, acute renal failure, and transfusion were associated with higher mortality (ORs of 2.29, 2.18, 1.93, 6.33, and 1.81, respectively; P < .001, .005, .011, <.001, and .005, respectively). CONCLUSIONS The 6-week mortality rate for variceal bleeding in children is 8.8%. Black or Hispanic children are at higher risk of dying. Serious morbidities associated with variceal hemorrhage impact mortality. These data can inform consideration of prophylactic or therapeutic interventions for children at risk.

Abstract
BACKGROUND Portal hypertension commonly accompanies advanced liver disease and often gives rise to life-threatening complications, including bleeding (haemorrhage) from oesophageal and gastrointestinal varices. Variceal bleeding commonly occurs in children and adolescents with chronic liver disease or portal vein thrombosis. Prevention is, therefore, important. Randomised clinical trials have shown that non-selective beta-blockers and endoscopic variceal band ligation decrease the incidence of variceal bleeding in adults. In children and adolescents, band ligation, beta-blockers, and sclerotherapy have been proposed as primary prophylaxis alternatives for oesophageal variceal bleeding. However, it is unknown whether these interventions are of benefit or harm when used for primary prophylaxis in children and adolescents. OBJECTIVES To assess the benefits and harms of band ligation compared with sham or no intervention for primary prophylaxis of oesophageal variceal bleeding in children and adolescents with chronic liver disease or portal vein thrombosis. SEARCH METHODS We searched the Cochrane Hepato-Biliary Group Controlled Trials Register, CENTRAL, PubMed, Embase, and two other databases (April 2020). We scrutinised the reference lists of the retrieved publications, and we also handsearched abstract books of the two main paediatric gastroenterology and hepatology conferences from January 2008 to December 2019. We also searched clinicaltrials.gov, the United States Food and Drug Administration (FDA), the European Medicines Agency (EMA), and the World Health Organization (WHO) for ongoing clinical trials. We imposed no language or document type restrictions on our search. SELECTION CRITERIA We aimed to include randomised clinical trials irrespective of blinding, language, or publication status, to assess the benefits and harms of band ligation versus sham or no intervention for primary prophylaxis of oesophageal variceal bleeding in children with chronic liver disease or portal vein thrombosis. If the search for randomised clinical trials retrieved quasi-randomised and other observational studies, then we read them through to extract information on harm. DATA COLLECTION AND ANALYSIS We used standard Cochrane methodology to perform this systematic review. We used GRADE to assess the certainty of evidence for each outcome. Our primary outcomes were all-cause mortality, serious adverse events and liver-related morbidity, and quality of life. Our secondary outcomes were oesophageal variceal bleeding and adverse events not considered serious. We used the intention-to-treat principle. We analysed data using Review Manager 5. MAIN RESULTS One conference abstract, describing a feasibility multi-centre randomised clinical trial, fulfilled our review inclusion criteria. We judged the trial at overall high risk of bias. This trial was conducted in three hospital centres in the United Kingdom. The aim of the trial was to determine the feasibility and safety of further larger randomised clinical trials of prophylactic band ligation versus no active treatment in children with portal hypertension and large oesophageal varices. Twelve children received prophylactic band ligation and 10 children received no active treatment. There was no information on the age of the children included, or about the diagnosis of any child included. All children were followed up for at least six months. Mortality was 8% (1/12) in the band ligation group versus 0% (0/10) in the no active intervention group (risk ratio (RR) 2.54, 95% confidence interval (CI) 0.11 to 56.25; very low certainty of evidence). The abstract did not report when the death occurred, but we assume it happened between the six-month follow-up and one year. No child (0%) in the band ligation group developed adverse events (RR 0.28, 95% CI 0.01 to 6.25; very low certainty of evidence) but one child out of 10 (10%) in the no active intervention group developed idiopathic thrombocytopaenic purpura. One child out of 12 (8%) in the band ligation group underwent liver transplantation versus none in the no active intervention group (0%) (RR 2.54, 95% CI 0.11 to 56.25; very low certainty of evidence). The trial reported no other serious adverse events or liver-related morbidity. Quality of life was not reported. Oesophageal variceal bleeding occurred in 8% (1/12) of the children in the band ligation group versus 30% (3/10) of the children in the no active intervention group (RR 0.28, 95% CI 0.03 to 2.27; very low certainty of evidence). No adverse events considered non-serious were reported. Two children were lost to follow-up by one-year. Ten children in total completed the trial at two-year follow-up. There was no information on funding. We found two observational studies on endoscopic variceal ligation when searching for randomised trials. One found no harm, and the other reported E nterobacter cloacae septicaemia in one child and mild, transient, upper oesophageal sphincter stenosis in another. We did not assess these studies for risk of bias. We did not find any ongoing randomised clinical trials of interest to our review. AUTHORS' CONCLUSIONS The evidence, obtained from only one feasibility randomised clinical trial at high risk of bias, is very scanty. It is very uncertain about whether prophylactic band ligation versus sham or no (active) intervention may affect mortality, serious adverse events and liver-related morbidity, or oesophageal variceal bleeding in children and adolescents with portal hypertension and large oesophageal varices. We have no data on quality of life. No adverse events considered non-serious were reported. The results presented in the trial need to be interpreted with caution. In addition, the highly limited data cover only part of our research question; namely, children with portal hypertension and large oesophageal varices. Data on children with portal vein thrombosis are lacking. Larger randomised clinical trials assessing the benefits and harms of band ligation compared with sham treatment for primary prophylaxis of oesophageal variceal bleeding in children and adolescents with chronic liver disease or portal vein thrombosis are needed. The trials should include important clinical outcomes such as death, quality of life, failure to control bleeding, and adverse events.

Our secondary outcomes were oesophageal variceal bleeding and adverse events not considered serious. We planned to use intention-to-treat principle. We planned to analyse data with RevMan Analysis. MAIN RESULTS We found no randomised clinical trials that assessed beta-blockers compared with sham or no intervention for primary prophylaxis of oesophageal variceal bleeding in children with chronic liver disease or portal vein thrombosis. We found four observational studies that reported on harms. As a systematic search for observational studies was not planned, we only listed the reported harms in a table. AUTHORS' CONCLUSIONS Randomised clinical trials assessing the benefits or harms of beta-blockers versus placebo or no intervention for primary prophylaxis of oesophageal variceal bleeding in children with chronic liver disease or portal vein thrombosis are lacking. Therefore, trials with adequate power and proper design, assessing the benefits and harms of beta-blockers versus placebo on patient-relevant clinical outcomes, such as mortality, quality of life, failure to control variceal bleeding, and adverse events are needed. Unless such trials are conducted and the results become published, we cannot make any conclusions regarding the benefits or harms of the two interventions.

Abstract
OBJECTIVES This study aimed to evaluate factors associated with upper digestive hemorrhage and primary and secondary endoscopic prophylaxis outcomes in children with extrahepatic portal vein obstruction. METHODS This observational and prospective study included 72 children with extrahepatic portal vein obstruction who were followed from 2005 to 2017. Risk factors associated with upper digestive hemorrhage and the results of primary and secondary prophylaxis of these patients were evaluated. RESULTS Fifty patients (69.4%) had one or more episodes of bleeding during follow-up, with a median age at first hemorrhage of 4.81 years. The multivariate analysis showed that medium- to large-caliber esophageal varices were associated with an 18-fold risk of upper digestive hemorrhage (95% CI: 4.33-74.76; p < 0.0001). Primary prophylaxis was administered to 14 patients, with eradication in 85.7%; however, 14.3% of these patients had hemorrhages during the follow-up period and 41.7% had a relapse of varices. Secondary prophylaxis was administered to 41 patients. Esophageal varices were eradicated in 90.2% of patients. There were relapse and re-bleeding of esophageal varices in 45.9% and 34.1% of the children, respectively. CONCLUSION Primary and secondary endoscopic prophylaxes showed high rates of esophageal varix eradication, but with significant relapses. Eradication of esophageal varices cannot definitively prevent recurrent upper digestive hemorrhage, since bleeding from alternate sites can occur. Medium- and large-caliber esophageal varices were associated with upper digestive hemorrhage in patients with extrahepatic portal vein obstruction. To the best of the authors' knowledge, this study is the first to evaluate bleeding risk factors in children with extrahepatic portal vein obstruction.

Abstract
BACKGROUND Portal hypertension commonly accompanies advanced liver disease and often gives rise to life-threatening complications, including bleeding (haemorrhage) from oesophageal and gastrointestinal varices. Variceal bleeding commonly occurs in children with chronic liver disease or portal vein obstruction. Therefore, prevention is important. Primary prophylaxis of variceal bleeding in adults is the established standard of care because of the results of numerous randomised clinical trials demonstrating the efficacy of non-selective beta-blockers or endoscopic variceal ligation in decreasing the incidence of variceal bleeding. In children, band ligation, beta-blockers, and sclerotherapy have been proposed as alternatives for primary prophylaxis of oesophageal variceal bleeding. However, it is unknown whether those treatments are of benefit or harm when used for primary prophylaxis in children. OBJECTIVES To assess the benefits and harms of sclerotherapy compared with sham or no intervention for primary prophylaxis of oesophageal variceal bleeding in children with chronic liver disease or portal vein thrombosis. SEARCH METHODS We searched The Cochrane Hepato-Biliary Group Controlled Trials Register, CENTRAL, PubMed, Embase Elsevier, and two other registers in February 2019. We scrutinised the reference lists of the retrieved publications, and performed a manual search of the main paediatric gastroenterology and hepatology conference (NASPGHAN and ESPGHAN) abstracts from January 2008 to December 2018. We searched four registries for ongoing clinical trials. There were no language or document type restrictions. SELECTION CRITERIA We included randomised clinical trials irrespective of blinding, language, or publication status assessing sclerotherapy versus sham or no intervention for primary prophylaxis of oesophageal variceal bleeding in children with chronic liver disease or portal vein thrombosis. DATA COLLECTION AND ANALYSIS We used standard Cochrane methodology to perform this systematic review. We used the intention-to-treat principle to analyse outcome data, and GRADE to assess the certainty of evidence per outcome. MAIN RESULTS We found only one randomised clinical trial that fulfilled our inclusion criteria. The trial was at high risk of bias. The trial included 108 Brazilian children with median age of 4.3 years (range 11 months to 13 years). Fifty-six children were randomised to prophylactic sclerotherapy (ethanolamine oleate 2%) and 52 children to no intervention (control). Children were followed up for a median of 4.5 years. Eight children (six from the sclerotherapy group versus two from the control group) dropped out before the end of the trial. The follow-up was from 18 months to eight years. Mortality was 16% (9/56 children) in the sclerotherapy group versus 15% (8/52 children) in the control group (risk ration (RR) 1.04, 95% confidence interval (CI) 0.44 to 2.50; very low-certainty evidence). Upper gastrointestinal bleeding occurred in 21% (12/56) of the children in the sclerotherapy group versus 46% (24/52) in the control group (RR 0.46, 95% CI 0.26 to 0.83; very low-certainty evidence). There were more children with congestive hypertensive gastropathy in the sclerotherapy group than in the control group (14% (8/56) versus 6% (3/52); RR 2.48, 95% CI 0.69 to 8.84; very low-certainty evidence). The incidence of gastric varices was similar between the sclerotherapy group and the control group (11% (6/56) versus 10% (5/52); RR 1.11, 95% CI 0.36 to 3.43; very low-certainty evidence). The incidence of bleeding from gastric varices was higher in the sclerotherapy group than in the control group (4% (3/56) versus 0% (0/52); RR 6.51, 95% CI 0.34 to 123.06; very low-certainty evidence). The study did not assess health-related quality of life. Oesophageal variceal bleeding occurred in 5% (3/56) of the children in the sclerotherapy group versus 40% (21/52) of the children in the control group (RR 0.13, 95% CI 0.04 to 0.42; very low-certainty evidence). The most prevalent complications (defined as non-serious) were pain and fever after the procedure, which promptly resolved with analgesics. However, numerical data on the frequency of these adverse events and their occurrences in the two groups were lacking. No funding information was provided. We found no ongoing trials. AUTHORS' CONCLUSIONS The evidence, obtained from one randomised clinical trial at high risk of bias, is very uncertain on whether sclerotherapy has an influence on mortality and if it may decrease first upper gastrointestinal or oesophageal variceal bleeding in children. The evidence is very uncertain on whether sclerotherapy has an influence on congestive hypertensive gastropathy, incidence on gastric varices, and incidence of bleeding from gastric varices. Health-related quality of life was not measured. There were no serious events caused by sclerotherapy, and analysis of non-serious adverse events could not be performed due to lack of numerical data. The GRADE assessment of each outcome showed a very low-certainty evidence. The results of the trial need to be interpreted with caution. Larger randomised clinical trials, following the SPIRIT and CONSORT statements, assessing the benefits and harms of sclerotherapy compared with sham or no intervention for primary prophylaxis of oesophageal variceal bleeding in children with chronic liver disease or portal vein thrombosis are needed. The trials should include important clinical outcomes such as death, failure to control bleeding, and adverse events.

AUTHORS' CONCLUSIONS Randomised clinical trials assessing the benefits or harms of sclerotherapy versus beta-blockers for primary prophylaxis of oesophageal variceal bleeding in children and adolescents with chronic liver disease or portal vein thrombosis are lacking. Therefore, trials with adequate power and proper design, assessing the benefits and harms of sclerotherapy versus beta-blockers on patient-relevant clinical outcomes such as mortality, failure to control bleeding, and adverse events are needed. Unless such trials are conducted and the results become published, we cannot make any conclusions regarding the benefits or harms of the two interventions.

Abstract
Primary prophylaxis in portal hypertension in children is controversial, because there are few studies documenting its efficacy on the risk of bleeding. Twenty-eight centres out of the 38 we contacted returned a completed questionnaire about their clinical practices. More than 75% of the centres use endoscopy to screen patients diagnosed with portal cavernoma, biliary atresia, cystic fibrosis, and other fibrotic chronic liver diseases with suspected portal hypertension. In cases of grade 2 varices with red marks and grade 3 varices >90% of centres perform sclerotherapy or endoscopic variceal ligation. Noncardioselective beta-blockers were used by approximately 20% of centres. In conclusion, despite the absence of scientific recommendations there is a tacit consensus concerning the need to screen children with clinical signs of portal hypertension, and to provide primary prophylaxis in cases of endoscopic patterns of high-risk varices.

Abstract
ABSTRACT BACKGROUND Bleeding of esophageal varices is the main cause of morbidity and mortality in children and adults with portal hypertension and there are few studies involving secondary prophylaxis in children and adolescents. OBJECTIVE To evaluate the efficacy of endoscopic secondary prophylaxis in prevention of upper gastrointestinal bleeding in children and adolescents with esophageal varices. METHODS This is a prospective analysis of 85 patients less than 18 years of age with or without cirrhosis, with portal hypertension. Participants underwent endoscopic secondary prophylaxis with sclerotherapy or band ligation. Eradication of varices, incidence of rebleeding, number of endoscopic sessions required for eradication, incidence of developing gastric fundus varices and portal hypertensive gastropathy were evaluated. RESULTS Band ligation was performed in 34 (40%) patients and sclerotherapy in 51 (60%) patients. Esophageal varices were eradicated in 81.2%, after a median of four endoscopic sessions. Varices relapsed in 38 (55.1%) patients. Thirty-six (42.3%) patients experienced rebleeding, and it was more prevalent in the group that received sclerotherapy. Gastric varices and portal hypertensive gastropathy developed in 38.7% and 57.9% of patients, respectively. Patients undergoing band ligation showed lower rebleeding rates (26.5% vs 52.9%) and fewer sessions required for eradication of esophageal varices (3.5 vs 5). CONCLUSION Secondary prophylaxis was effective in eradicating esophageal varices and controlling new upper gastrointestinal bleeding episodes due to the rupture of esophageal varices. Band ligation seems that resulted in lower rebleeding rates and fewer sessions required to eradicate varices than did sclerotherapy.

Abstract
OBJECTIVE Bleeding of esophageal varices is the main cause of morbidity and mortality in children with portal hypertension. It is important to understand the factors related with a bleeding episode to evaluate more effective primary prophylaxis. The present study aims to describe the endoscopic and laboratory findings associated with upper gastrointestinal bleeding (UGIB) secondary to esophageal varices. METHOD A cross-sectional study with 103 children and adolescents with cirrhosis, divided into a group that had experienced an episode of upper UGIB (35 patients) and a group without a history of UGIB (68 patients), was carried out. The esophageal and gastric varices were classified, and the portal hypertensive gastropathy, laboratory findings, and Child-Pugh classification were measured. RESULTS Factors observed in univariate analysis to be associated with UGIB were the presence of esophageal varices of medium caliber or larger, portal hypertensive gastropathy, presence of red spots on esophageal varices, Child-Pugh class B or C, and hypoalbuminemia (P < 0.05). After multivariate logistic regression analysis, the significant factors were the presence of red spots on esophageal varices and the presence of gastric varices. When separated the autoimmune hepatitis, nonbiliary atresia patients (all patients except the patients with biliary atresia), and biliary atresia groups the findings in the univariate analysis were the presence of esophageal varices of medium or larger caliber, presence of red spots on varices, and presence of gastric varices in the autoimmune hepatitis patients and nonbiliary atresia patients and presence of red spots on esophageal varices, presence of gastric varices, and Child-Pugh classification B or C in biliary atresia group (P < 0.05). After multivariate logistic regression analysis, no statistical significance was found for any factor analyzed in any groups. CONCLUSIONS The presence of gastric varices and red spots on esophageal varices were related to episodes of UGIB secondary to rupture of esophageal varices. When these findings are observed, indications for endoscopic primary prophylaxis should be evaluated. More studies are, however, necessary to better understand this problem.

Abstract
In patients with advanced liver disease with portal hypertension, portal-systemic collaterals contribute to circulatory disturbance, gastrointestinal hemorrhage, hepatic encephalopathy, ascites, hepatopulmonary syndrome and portopulmonary hypertension. Angiogenesis has a pivotal role in the formation of portal-systemic shunts. Recent research has defined many of the mediators and mechanisms involved in this angiogenic process, linking the central roles of hepatic stellate cells and endothelial cells. Studies of animal models have demonstrated the potential therapeutic impact of drugs to inhibit angiogenesis in cirrhosis. For example, inhibition of VEGF reduces portal pressure, hyperdynamic splanchnic circulation, portosystemic collateralization and liver fibrosis. An improved understanding of the role of other angiogenic factors provides hope for a novel targeted therapy for portal hypertension with a tolerable adverse effect profile.

Abstract
AIM To determine the laboratory and radiologic parameters, including the platelet count (PC)-to-spleen diameter (SD) ratio as a non-invasive marker that may predict the presence of esophageal varices (EV) in children with cirrhosis.
METHODS Eighty-nine patients with cirrhosis, but without a history of variceal bleeding were prospectively included. The children were grouped into 6-12 and 12-18 years of age groups. These groups were also divided into 2 sub-groups (presence and absence of EV). All of the patients underwent a complete biochemical and radiologic evaluation. The PC (n/mm3)-to-SD (mm) ratio was calculated for each patient.
RESULTS Sixty-nine of 98 (70.4%) patients had EV. The presence of ascites in all age groups was significantly associated with the presence of EV. There were no differences in serum albumin levels, PC, SD and the PC-to-SD ratio between the presence and absence of EV groups in both age groups (P > 0.05).
CONCLUSION Laboratory and radiologic parameters, including the PC-to-SD ratio as a non-invasive marker (except for the presence of ascites), was inappropriate for detecting EV in children with cirrhosis.

Abstract
OBJECTIVES To evaluate the feasibility and efficacy of transjugular intrahepatic portosystemic shunt (TIPS) for extrahepatic portal venous obstruction with recurrent variceal bleeding in children. METHODS From November 2005 to December 2013, 28 consecutive paediatric patients with extrahepatic portal venous obstruction treated with TIPS for recurrent variceal bleeding refractory to medical/endoscopic therapy and/or surgical treatment in a tertiary-care centre were followed until last clinical evaluation or death. The median follow-up time was 36.0 months (range 4.0-106.0 months). RESULTS Seventeen boys and 11 girls of ages 7.1 to 17.9 years (median 12.3 years) weighing 19.0 to 62.0 kg (median 33.5 kg) were treated. TIPS was successfully placed in 17 of 28 (60.7%) patients via a transjugular approach alone (n = 4), a combined transjugular/transhepatic approach (n = 9), or a combined transjugular/transsplenic approach (n = 4). Shunt dysfunction occurred in 6 of 17 (35.3%) patients. The cumulative 1- and 3-year free-from-variceal-rebleeding rates in TIPS success group were higher than those in TIPS failure group (75.0% and 67.5% vs 45.5% and 18.2%, respectively, P = 0.0075). Compared with the TIPS failure group, the improvements in the height-for-age z scores were greater in the TIPS success group (P = 0.017). Procedure-related complication occurred in 1 patient (3.6%), and no episode of post-TIPS hepatic encephalopathy occurred in any patient. Except 1 patient in the TIPS success group died at 115 postoperative days, all patients were alive. CONCLUSIONS TIPS is feasible and effective in children with extrahepatic portal venous obstruction and recurrent variceal bleeding. TIPS could represent a less-invasive alternative to traditional surgical portosystemic shunting or a valuable treatment option if surgery and endoscopic treatment failed.

Abstract
OBJECTIVES Data regarding agreement on endoscopic features of oesophageal varices in children with portal hypertension (PH) are scant. The aim of this study was to evaluate endoscopic visualisation and classification of oesophageal varices in children by several European clinicians, to build a rational basis for future multicentre trials. METHODS Endoscopic pictures of the distal oesophagus of 100 children with a clinical diagnosis of PH were distributed to 10 endoscopists. Observers were requested to classify variceal size according to a 3-degree scale (small, medium, and large, class A), a 2-degree scale (small and large, class B), and to recognise red wales (presence or absence, class Red). Overall agreement was considered fair if Fleiss and Cohen κ test was ≥0.30, good if ≥0.40, excellent if ≥0.60, and perfect if ≥0.80. RESULTS Agreement between observers was fair with class A (κ = 0.34) and class B (κ = 0.38), and good with class Red (κ = 0.49). The agreement was good on presence versus absence of varices (class A = 0.53, class B = 0.48). The agreement among the observers was good in class A when endoscopic features of severe PH (medium and large sizes, red marks) were grouped and compared with mild features (absent and small varices) (κ = 0.58). CONCLUSIONS Experts working in different centres show a fairly good agreement on endoscopic features of PH in children, although a better training of paediatric endoscopists may improve the agreement in grading severity of varices in this setting.

Esophageal varices in children with portal hypertension are quite common. Bleeding from these varices frequently occurs. Prophylactic measures to prevent such bleeding can be undertaken either before ("primary," prompted by a screening endoscopy) or after ("secondary") an initial variceal bleed. There are no clear pediatric guidelines for primary or secondary prophylaxis of esophageal varices. Adult studies clearly support the use of pharmacologic (beta blockers) and endoscopic (endoscopic band ligation, EBL) management for both primary and secondary prophylaxis of esophageal varices in patients with portal hypertension. Pediatric studies are limited. There are inadequate data to recommend use of beta blockers to prevent variceal bleeding or rebleeding in children with portal hypertension. There is very limited support for EBL for primary prophylaxis in children and more compelling support for EBL for secondary prophylaxis. Further randomized controlled studies are needed but are difficult to implement in this vulnerable population.

Abstract
Portal hypertension is one of the most serious complications of childhood liver disease, and variceal bleeding is the most feared complication. Most portal hypertension results from cirrhosis but extra hepatic portal vein obstruction is the single commonest cause. Upper gastrointestinal endoscopy endoscopy remains necessary to diagnose gastro-esophageal varices. Families of children with portal hypertension should be provided with written instructions in case of gastrointestinal bleeding. Children with large varices should be considered for primary prophylaxis on a case-by-case basis. The preferred method is variceal band ligation. Children with acute bleeding should be admitted to hospital and treated with antibiotics and pharmacotherapy before urgent therapeutic endoscopy. All children who have bled should then receive secondary prophylaxis. The preferred method is variceal band ligation and as yet there is little evidence to support the use of β-blockers. Children with extrahepatic portal vein obstruction should be assessed for suitability of mesoportal bypass.

Abstract
Late portal vein thrombosis with cavernomatous replacement has been reported in 4.5% of pediatric patients who have undergone partial liver transplantation. In such cases, minimally invasive radiological treatments have a high failure rate. We report a successful case of percutaneous recanalization of the portal vein remnant, and subsequent stent placement, in a pediatric patient who underwent left lateral split liver transplantation with cavernomatous replacement of the portal vein.

Abstract
BACKGROUND Children with extrahepatic portal hypertension typically present with cavernomatous transformation of the portal vein and a poorly defined intrahepatic portal vein system on conventional imaging. With the Meso-Rex Bypass becoming the gold-standard intervention for a cure, a precise assessment of the intrahepatic portal vein system provides helpful data for deciding whether a Meso-Rex Bypass is feasible or not. METHODS All children with extrahepatic portal hypertension were prospectively assessed by wedged hepatic venous portography. Venous anatomy was categorized into five subtypes (A to E), depending on the presence of thrombosis in the Rex recessus, or not, and its extension within the intrahepatic portal venous system. RESULTS Eighty-nine children entered the study. Previous umbilical vein catheterization is usually associated with Rex thrombosis, while the Rex recessus and the intrahepatic portal venous system are patent in idiopathic cases, thus allowing for the performance of a Meso-Rex Bypass with a good outcome. CONCLUSIONS Wedged hepatic venous portography is a very effective tool for detailed preoperative assessment and identification of children being considered for Meso-Rex Bypass surgery. An anatomic-radiological classification is useful in selecting patients for Meso-Rex Bypass with anticipation of a high rate of success.

Abstract
BACKGROUND The aim of this study is to evaluate if symptomatic or asymptomatic PVT, as diagnosed with ultrasonography (US), occurs more often in children after the introduction and implementation of LS compared to open splenectomy. METHODS A retrospective cohort of 76 splenectomized patients for benign hematological disease were analyzed, 24 after open splenectomy (OS) and 52 after LS. RESULTS In six of the OS and 40 after LS a postoperative US was obtained. In two patients after LS, a PVT was seen on US. Both patients were symptomatic and also underwent a laparoscopic cholecystectomy. The length of stay in the hospital was significantly shorter for LS (median 4.5 days, range 2-12) compared to OS (median 7 days, range 5-12), (P=.00). Median operation time of OS was 65 min (range 35-130 min) and of LS 170 min (range 85-275 min) (P=.00). There was no difference in postoperative complications. CONCLUSION The risk of developing a PVT after laparoscopic splenectomy seems low, and thus LS is not contraindicated in patients with benign hematological disease. When combining LS and laparoscopic cholecystectomy, prophylactic heparin might be considered.

Abstract
After an episode of acute bleeding from esophageal varices, patients are at a high risk for recurrent bleeding and death. However, there are few reports regarding the long-term results of secondary prophylaxis using endoscopic variceal ligation (EVL) against variceal rebleeding in pediatrics. Thirty-seven, who were followed for over 3 yr post-eradication, were included in the study. The mean duration of follow up after esophageal variceal eradication was 6.4±1.9 yr. The mean time required to achieve the eradication of varices was 3.25 months. The mean number of sessions and O-bands needed to eradicate varices was 1.9±1.2 and 3.8±1.5, respectively. During the period before the first EVL treatment, 145 episodes of bleedings developed in 37 children. Over the 3 yr of follow-up after variceal eradication, only 4 episodes of rebleeding developed in 4 of 37 patients. The four rebleeding episodes consisted of an esophageal variceal bleed, a gastric variceal bleed, a duodenal ulcer bleed, and a bleed caused by hemorrhagic gastritis. There was no mortality during long-term follow up after variceal eradication. During long-term follow up after esophageal variceal eradication using solely EVL in children with esophageal variceal bleeds, rebleeding episodes and recurrence of esophageal varices were rare. EVL is a safe and highly effective method for the long-term prophylaxis of variceal rebleeding in children with portal hypertension.

Abstract
BACKGROUND AND AIM In patients with extrahepatic portal venous obstruction (EHO), death is usually due to variceal bleeding. This is more so in developing countries where there is a lack of tertiary health-care facilities and blood banks. Prophylactic operations in cirrhotics have been found to be deleterious. In contrast, patients with EHO have well-preserved liver function, and we therefore investigated the role of prophylactic surgery to prevent variceal bleeding. METHODS Between 1976 and 2010, we operated on selected patients with EHO, who had no history of variceal bleeding but had "high-risk" esophagogastric varices or severe portal hypertensive gastropathy and/or hypersplenism, and came from remote areas with poor access to tertiary health care. Following surgery, these patients were prospectively followed up with regard to mortality, variceal bleeding, encephalopathy, and liver function. RESULTS A total of 114 patients (67 males; mean age 19 years) underwent prophylactic operations (proximal splenorenal shunts 98 [86%]; esophagogastric devascularization 16). Postoperative mortality was 0.9%. Among 89(79%) patients who were followed up (mean 60 months), hypersplenism was cured, and six (6.7%) developed variceal bleeding. The latter were managed successfully by endoscopic sclerotherapy. No patient developed overwhelming post-splenectomy sepsis or encephalopathy, and 90% were free of symptoms. CONCLUSION In patients with EHO, prophylactic surgery is fairly safe and prevents variceal bleeding in ∼ 94% of patients with no occurrence of portosystemic encephalopathy. Patients with EHO who have not bled but have high-risk varices and/or hypersplenism, and poor access to medical facilities should be offered prophylactic operations.

Abstract
OBJECTIVE The aim of this study was to describe the results of endoscopic secondary prophylaxis, alone or in combination with propranolol, used to prevent upper gastrointestinal bleeding (UGIB) in children and adolescents with esophageal varices. METHODS This observational study followed 43 patients younger than 18 years who received secondary prophylaxis between August 2001 and December 2009. Sclerotherapy and/or band ligation were performed, and propranolol was used when no contraindications were present. The rebleeding rate, number of endoscopic sessions required for variceal eradication, rate of varix recurrence, the occurrence of varices at the gastric fundus, and the occurrence of portal hypertensive gastropathy were evaluated. RESULTS Endoscopic prophylaxis in combination with propranolol was performed in 25 patients (58.1%) and endoscopic prophylaxis alone was performed in 18 patients (41.9%). Esophageal varices were eradicated in all of the patients after a median of 3 sessions. Varices recurred in 22 patients (51.2%). Rebleeding occurred in 13 patients (30.2%). Fundal varices and portal hypertensive gastropathy developed in 31% and 61.9% of patients, respectively. No deaths related to the endoscopic procedure or UGIB occurred. No statistically significant differences in any of the studied variables were observed when comparing endoscopic prophylaxis with propranolol and endoscopic prophylaxis alone. CONCLUSIONS No significant differences were observed between sclerotherapy and band ligation. Secondary prophylaxis was effective in eradicating esophageal varices. The use of propranolol did not affect the results of the endoscopic prophylaxis. Furthermore, randomized studies will be necessary to assess the best form of prevention during childhood.

Abstract
Portal hypertension (PH) is a common complication of chronic liver disease in children and represents a cause of morbidity and, rarely, mortality in this group of patients. Although often self-limiting, gastrointestinal bleeding in this setting is regarded as a frightening event by patients and carers, giving the impression of impending death. Therefore, it is important to raise the awareness on the natural history of PH in children, the utility of tools that help preventing and managing acute bleeding, and the signs predicting a poor outcome, thus indicating surgery. There is lack of data on the ability of endoscopy screening, endoscopic treatment of varices, and use of nonselective β-blockers to alter the outcome of PH in children; major efforts should be made to avoid such treatments empirically and promote multicenter trials instead. Nevertheless, such approach should be balanced against the need of offering the best care to children with PH. In this review, we discuss the advances made in the management of PH in children and compare it with the larger adult experience. A rational approach to acute gastrointestinal bleeding is proposed along with an algorithm suggesting a stepwise protocol to manage children with esophageal varices in the long-term, with some hints on possible future studies.

Abstract
The management of children with portal hypertension has dramatically changed during the past decade, with an improvement in outcome. This has been achieved by improved efficiency of endoscopic variceal control and the success of liver transplantation. Emergency surgical shunt procedures are rarely required, with acute bleeding episodes generally controlled endoscopically or, occasionally in adults, by interventional radiological procedures. Portosystemic shunts may be considered as a bridge to transplant in adults but are rarely used in this context in children. Nontransplant surgery or radiological interventions may still be indicated for noncirrhotic portal hypertension when the primary cause can be cured and to allow normalization of portal pressure before liver parenchyma is damaged by chronic secondary changes in some specific diseases. The meso-Rex bypass shunt is used widely but is limited to those with a favorable anatomy and can even be performed preemptively. Elective portosystemic shunt surgery is reserved for failure to respond to conservative management in the absence of alternative therapies.

Abstract
PORTAL HYPERTENSION IN CHILDREN REPRESENTS A PARTICULAR DIAGNOSTIC AND MANAGEMENT CHALLENGE FOR SEVERAL REASONS: (1) treatment outcomes should be evaluated in relationship with a long-life expectancy, (2) pediatric patients with portal hypertension constitute an heterogeneous population, both in terms of individual characteristics and diversity of liver diseases; making comparison between treatment outcomes very difficult, (3) application of techniques and procedures developed in adult patients (v.gr. TIPS) face size limitations in small children, and (4) absence of data from well-controlled trials in children forces pediatric specialists to adapt results obtained from adult cohorts suffering from diseases such as HCV and alcoholic cirrhosis. Despite those limitations, substantial progress in the treatment of children with portal hypertension has been achieved in recent years, with better outcomes and survival. Two main factors influence our therapeutic decision: age of the patient and etiology of the liver disease. Therefore, diagnosis and treatment of complications of portal hypertension in children need to be described taking such factors into consideration. This paper summarizes current knowledge and expert opinion.

Abstract
BACKGROUND & AIMS The validation of noninvasive tests to diagnose esophageal varices is a priority in children because repeated endoscopic evaluations are too invasive. We measured the ability of a previously developed noninvasive clinical prediction rule (CPR) to predict the presence of esophageal varices in children. METHODS We analyzed data from 108 children, younger than age 18, who received endoscopies at 8 centers, to assess portal hypertension from chronic liver disease or portal vein obstruction. Blood test and abdominal ultrasound scan results were obtained within 4 months of endoscopy. Grading of varices identified by endoscopy was confirmed by independent blinded review. Spleen size, based on data from the ultrasound scan, was expressed as a standard deviation score relative to normal values for age. RESULTS Of the children studied, 74 had esophageal varices (69%), including 35 with large varices (32%). The best noninvasive predictors of esophageal varices of any size were as follows: platelet:spleen size z-score ratio (area under the receiver operating characteristic curve [AUROC], 0.84; 95% confidence interval [CI] 0.75-0.93), CPR (AUROC, 0.80; 95% CI, 0.70-0.91), and platelet count (AUROC, 0.79; 95% CI, 0.69-0.90). The positive predictive values for the CPR and platelet count were 0.87 and 0.86, the negative predictive values were 0.64 and 0.63, the positive likelihood ratios were 3.06 and 2.76, and the negative likelihood ratios were 0.64 and 0.63, respectively. Based on positive and negative predictive values, the most accurate noninvasive tests were the CPR and platelet counts. CONCLUSIONS Noninvasive tests such as CPR and platelet count can assist in triaging children for endoscopy to identify esophageal varices.

Abstract
Neonatal portal vein thrombosis (PVT) is an increasingly recognized event. Patients are generally asymptomatic in the neonatal period. The diagnosis is made with Doppler ultrasound. Umbilical catheterization, exchange transfusion and sepsis are risk factors for neonatal PVT. Thrombophilia is possibly a contributing risk factor. Although there are potential serious acute complications such as hepatic necrosis, the outcome is good in the majority of cases, followed up to 8 years of age. Thrombus resolution occurs in 30-70% in days to months. Liver lobe atrophy may occur following PVT, and does not appear to be associated with any impairment of liver function. Non-occlusive thrombosis is more likely to resolve than non-occlusive thrombosis. A subset of patients without resolution is at risk for developing portal hypertension over the next decade of life. There are no current defining features present during the neonatal period to enable identification of neonates at risk for portal hypertension. There is no evidence that anticoagulation therapy improves time to resolution or decreases the likelihood of portal hypertension. Anticoagulation therapy may be considered. A management algorithm is proposed.

Abstract
BACKGROUND AND AIMS Inadequate evidence to guide the management of children with esophageal varices may lead to variation in care and the provision of poor-quality care to some children. The aims of the study were to describe approaches taken by pediatric gastroenterologists for the management of esophageal varices in children, and to determine the attitudes of children, parents, and physicians toward screening endoscopy for identification of varices. METHODS Canadian pediatric gastroenterologists and hepatologists were questioned about their approaches to screening for esophageal varices and therapy to prevent or treat variceal hemorrhage. Consecutive children with portal hypertension and their parents were surveyed about attitudes to screening endoscopy. RESULTS Forty-seven of 72 (65%) physicians responded. Seventy percent of respondents screen for esophageal varices in selected children, most using endoscopy (77%). Fifty-eight percent of respondents who screen for varices would provide primary prophylactic treatment. Most would treat an acute variceal bleed with antibiotics, acid suppression, octreotide, and endoscopy within 24 hours (76%) and then secondary prophylaxis with endoscopic variceal ligation (96%) or β-blockers (28%). Among 29 families surveyed, 63% of parents and 50% of patients would agree to screening endoscopy to understand their risk of variceal bleeding and 67% if prophylactic therapy were available. Families were more concerned about the risk of endoscopic adverse events than were gastroenterologists. CONCLUSIONS Pediatric gastroenterologists vary in the care they provide for children at risk for esophageal varices and their attitudes toward the role of screening endoscopy differ from that of their patients. Further evidence is required to support practice guidelines that may reduce variation in care and thus improve its quality.

Abstract
Nonselective β-blocker therapy and endoscopic variceal ligation reduce the incidence of variceal hemorrhage in cirrhotic adults, but their use in children is controversial. There are no evidence-based recommendations for the prophylactic management of children at risk of variceal hemorrhage due to the lack of appropriate randomized controlled trials. In a recent gathering of experts at the American Association for the Study of Liver Diseases annual meeting, significant challenges were identified in attempting to design and implement a clinical trial of primary prophylaxis in children using either of these therapies. These challenges render such a trial unfeasible, primarily due to the large sample size required, inadequate knowledge of appropriate dosing of β-blockers, and difficulty in recruiting to a trial of endoscopic variceal ligation. Pediatric research should focus on addressing questions of natural history and diagnosis of varices, prediction of variceal bleeding, optimal approaches to β-blocker and ligation therapy, and alternative study designs to explore therapeutic efficacy in children.

Derivation of a clinical prediction rule for the noninvasive diagnosis of varices in children. J Pediatr Gastroenterol Nutr 2010; 50:188-93.

Abstract
BACKGROUND AND OBJECTIVES Identification of children who are at high risk for having varices using noninvasive tests would enable the selection of children for future studies of primary prophylaxis of variceal hemorrhage, but this has been inadequately studied. The objective of the study was to derive a noninvasive clinical prediction rule that is able to identify children with esophageal varices. METHODS Fifty-one consecutive children with liver disease or portal hypertension who underwent endoscopy were included in the present retrospective study. At endoscopy, variceal size was graded on a 4-point Likert scale. Results of physical examination, blood tests, and abdominal ultrasound scan (USS) were recorded. Spleen length on USS was expressed as a standard deviation score (z score). A descriptive univariate analysis was performed on variables that were potentially associated with esophageal varices and multivariate logistic regression was then modeled to derive a clinical prediction rule. RESULTS Esophageal varices were found in 17 of the 51 children (33%). Variables found to differ significantly between children with and without varices included platelet/spleen-length z score ratio (P < 0.001), platelet count (P < 0.001), international normalized ratio (P = 0.001), aspartate aminotransferase/alanine aminotransferase ratio (P = 0.002), and albumin (P = 0.003). Using multivariate logistic regression, a model with platelet count, spleen length z score, and albumin as the independent variables had the best fit. Area under the receiver operating characteristic curve for this clinical prediction rule was 0.93 (95% confidence interval 0.85-0.99), sensitivity 94%, specificity 81%, positive predictive value 0.83, negative predictive value 0.94, positive likelihood ratio 5, and negative likelihood ratio 0.06. CONCLUSIONS This clinical prediction rule is a simple noninvasive measure that may identify children at high risk for esophageal varices. A prospective validation study is in progress.

Abstract
Venous thrombosis results from the convergence of vessel wall injury and/or venous stasis, known as local triggering factors, and the occurrence of acquired and/or inherited thrombophilia, also known as systemic prothrombotic risk factors. Portal vein thrombosis (PVT) and Budd-Chiari syndrome (BCS) are caused by thrombosis and/or obstruction of the extrahepatic portal veins and the hepatic venous outflow tract, respectively. Several divergent prothrombotic disorders may underlie these distinct forms of large vessel thrombosis. While cirrhotic PVT is relatively common, especially in advanced liver disease, noncirrhotic and nontumoral PVT is rare and BCS is of intermediate incidence. In this article, we review pathogenic mechanisms and current concepts of patient management.

Abstract
PURPOSE Massive splenomegaly with severe hypersplenism can occur as a late complication of portal hypertension (PH) caused by extrahepatic portal venous obstruction (EHPVO) in children. Severe hypersplenism is often refractory to treatment with endoscopic sclerotherapy (EST) and shunt surgery. We report our experience of managing this disorder surgically. METHODS We performed splenectomy and esophagogastric devascularization via laparotomy in 14 children with an average age of 9.7 years. Upper gastrointestinal endoscopy had shown esophageal varices of varying grade, and EST had been done for patients with a history of bleeding. The indications for surgery were pain and discomfort caused by a large spleen greater than 15 cm below the costal margin, and intractable symptomatic hypersplenism with a total leukocyte count <2500/mm3 and a platelet count <50,000/mm3, or both. RESULTS Postoperative recovery was uneventful and the leukocyte and platelet counts reverted to normal. After follow-up for 1-5 years, all 14 children were asymptomatic, with improved growth and nutrition and no reported episodes of gastrointestinal bleeding, sepsis, or encephalopathy. CONCLUSION Splenectomy with devascularization is effective for children with massive splenomegaly and severe hypersplenism secondary to EHPVO.
