Abstract
Portal hypertensive bleeding is a major complication of portal hypertension (PHT) with high morbidity and mortality. A lot of advances have been made in our understanding of screening, risk stratification, and management strategies for portal hypertensive bleeding including acute variceal bleeding leading to improved overall outcomes in patients with PHT. A number of guidelines on variceal bleeding have been published by various societies in the past few years. The Indian Society of Gastroenterology (ISG) Task Force on Upper Gastrointestinal Bleeding (UGIB) felt that it was necessary to bring out a standard practice guidance document for the use of Indian health care providers especially physicians, gastroenterologists, and hepatologists. For this purpose, an expert group meeting was convened by the ISG Task Force to deliberate on this matter and write a consensus guidance document for Indian practice. The delegates including gastroenterologists, hepatologists, radiologists, and surgeons from different parts of the country participated in the consensus development meeting at Coorg in 2018. A core group was constituted which reviewed all published literature on portal hypertensive UGIB with special reference to the Indian scenario and prepared unambiguous statements on different aspects for voting and consensus in the whole group. This consensus was produced through a modified Delphi process and reflects our current understanding and recommendations for the diagnosis and management of portal hypertensive UGIB in Indians. Intended for use by the health care providers especially gastroenterologists and hepatologists, these consensus statements provide an evidence-based approach to risk stratification, diagnosis, and management of patients with portal hypertensive bleeding.

Abstract
BACKGROUND Endoscopic variceal ligation (EVL) is a widely accepted treatment for esophagogastric varices in patients with portal hypertension (PHT). It is used for urgent treatment and prophylactic treatment of esophagogastric varices in pediatric as well as adult patients. However, major life-threatening adverse events such as early rebleeding can occur. Although early rebleeding after EVL among children and adolescents has been reported, the risk factors remain obscure. This study evaluated the risk factors for early rebleeding after EVL in children and adolescents. METHODS The subjects were children and adolescents (<18 years) with PHT who underwent EVL for esophagogastric varices. Early rebleeding was defined as hematemesis, active bleeding, or blood retention in the stomach, confirmed by esophagogastroduodenoscopy from 2 h to 5 days after EVL. RESULTS A total of 50 EVL sessions on 22 patients were eligible for this study. There were four episodes of early rebleeding. No other major adverse event has occurred. Multivariate analysis showed that EVL implemented at cardiac varices just below the esophagogastric junction (EGJ), within 5 mm from the EGJ, is the independent factor for a higher risk of early rebleeding: odds ratio 18.2 (95% confidence interval: 1.40-237.0), P = 0.02. CONCLUSIONS Children and adolescents who undergo EVL for cardiac varices just below the EGJ have a higher risk of early rebleeding than those who do not.

Splenic stiffness and platelet count to predict varices needing treatment in pediatric extrahepatic portal vein obstruction. Indian J Gastroenterol 2020; 39:576-583. [PMID: 33231766 DOI: 10.1007/s12664-020-01099-8] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/30/2020] [Accepted: 09/16/2020] [Indexed: 02/04/2023]
Abstract
BACKGROUND Surveillance endoscopy to detect varices needing treatment (VNT) is important to prevent bleeding and morbidity in portal hypertension. In adult and pediatric cirrhosis, platelet count and liver stiffness measurement (LSM) are useful in selecting patients for endoscopy. Such recommendations do not exist for extrahepatic portal vein obstruction (EHPVO). Splenic stiffness measurement (SSM) has been studied in adult and pediatric EHPVO with conflicting results and methodological errors. This study evaluates the role of platelet counts and SSM to predict VNT and bleeding in pediatric EHPVO while comparing LSM and SSM between pediatric EHPVO and controls. METHODS One hundred and seven children (55 with EHPVO and 52 controls) were recruited. Clinical, biochemical, hematological, and radiographic parameters of all children were noted. All children with EHPVO underwent endoscopy. RESULTS Of the 55 children with EHPVO, 48 (87.3%) had VNT. There was no difference in the platelet counts (85,000/mm3 vs. 120,000/mm3, p = 0.58) and SSM (3.62 vs. 3.19, p = 0.05) between EHPVO children with VNT and those without. They had poor sensitivity and specificity to predict VNT. EHPVO children with bleeding had higher SSM that those without. LSM was higher among EHPVO than among controls (1.19 vs. 1.10, p = 0.003). Those with LSM higher than controls had normal liver histology. CONCLUSION SSM is higher in EHPVO bleeders but SSM and platelet counts are unreliable to predict VNT in pediatric EHPVO. Surveillance endoscopies may be needed in all pediatric EHPVO until better screening strategies are available. TRIAL REGISTRATION Not applicable.

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
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
Background and study aims: In view of the paucity of literature, we carried out this audit to evaluate the safety and efficacy of N- butyl, 2-cynoacrylate glue injection therapy in secondary prophylaxis of gastric varices in children. Patients and methods: Consecutive children (≤ 18 years) with non-cirrhotic portal hypertension who presented with bleeding from gastric varices and who had undergone cyanoacrylate glue injection therapy were included. They were evaluated for safety, efficacy and complications. Their long-term outcomes and follow-up were recorded. Results: Over 11 years, 28 children with median age 13 (range, 8 to 18) years (68 % boys), underwent cyanoacrylate glue injection for bleeding gastric varices. In 25 (89 %) cases, extrahepatic portal venous obstruction was the etiology and isolated gastric varices were the source of the bleeding. Primary and secondary gastric variceal bleeding was seen in 11 (39 %) and 17 (61 %) children, respectively. A total 36 sessions with median volume of 2 (range, 1 - 5) mL of glue injections were required (2 sessions in 8 children). Hemostasis was achieved in all and 57 % had gastric variceal obliteration. Two children had early (< 1 month) rebleeding and 2 children had late rebleeding. One child had gastric ulcer. Over a median follow-up of 24 (8 - 98) months, 14 children underwent surgery (12 porto-systemic shunt), 2 were lost to follow-up, 1 died and there was no recurrence of bleeding in the remaining 11. Conclusions: Cyanoacrylate glue injection is highly effective mode of secondary prophylaxis of bleeding gastric varices in children with non-cirrhotic portal hypertension. Rebleeding occurred in 14 % but treatment-related complications were uncommon. However, a large controlled clinical trial is required to confirm our findings.

Abstract
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
OBJECTIVES To study the demographic features, etiology, clinical, radiology and laboratory findings in children with Extra hepatic portal vein obstruction (EHPVO) from the North Indian Gangetic Plain. METHODS A prospective analysis of 53 patients of EHPVO (<14 y of age) was done. Data for clinical presentation, laboratory workup, endoscopic procedures, growth and development, management and outcome were analyzed. RESULTS A total of 53 patients (32 male, 21 female) with mean age of 8.66 ± 3.32 y at presentation were included. Growth retardation was present in 30 (56.60 %) patients at time of diagnosis. The most common presenting symptoms were upper gastrointestinal bleeding (86.80 %) and an incidental finding of splenomegaly (13.2 %). Hematological parameters of hypersplenism were present in 9 (17 %) patients. Protein C (PC), Protein S (PS), antithrombin III (AT) deficiency were found in 8 (20 %), 4 (10 %) and 6 (15 %) of the patients respectively in 40 patients tested. On first endoscopy, esophageal varices were present in all patients. Endoscopic sclerotherapy (EST)/band ligation (EBL) was performed in 46 bleeder patients and success rate was 83.3 % for sclerotherapy and 90 % for band ligation. CONCLUSIONS The etiology of EHPVO in the majority of patients remains elusive. It results in impaired somatic growth. Sclerotherapy and endoscopic banding are effective means for treatment for bleeding varices. It is still not clear whether deficiency of anticoagulant proteins is a primary event or secondary to disease process.

Abstract
NCPH is a heterogeneous group of liver disorders of vascular origin, leading to PHT with near normal HVPG. NCPF/IPH is a disorder of young adults or middle aged women, whereas EHPVO is a disorder of childhood. Early age acute or recurrent infections in an individual with thrombotic predisposition constitute the likely pathogenesis. Both disorders present with clinically significant PHT with preserved liver functions. Diagnosis is easy and can often be made clinically with support from imaging modalities. Management centers on control and prophylaxis of variceal bleeding. In EHPVO, there are additional concerns of growth faltering, portal biliopathy, MHE and parenchymal dysfunction. Surgical shunts are indicated in patients with failure of endotherapy, bleeding from sites not amenable to endotherapy, symptomatic hypersplenism or symptomatic biliopathy. Persistent growth failure, symptomatic and recurrent hepatic encephalopathy, impaired quality of life or massive splenomegaly that interferes with daily activities are other surgical indications. Rex-shunt or MLPVB is the recommended shunt for EHPVO, but needs proper pre-operative radiological assessment and surgical expertise. Both disorders have otherwise a fairly good prognosis, but need regular and careful surveillance. Hepatic schistosomiasis, CHF and NRH have similar presentation and comparable prognosis.

Abstract
PURPOSE The aim of this study was to compare the efficacy and safety of band ligation and injection sclerotherapy in the endoscopic treatment of children with variceal bleeding. METHODS The study population included 55 children, all of whom were treated at the time of endoscopic diagnosis of esophageal varices at Asan Medical Center, Seoul, Korea, between January 1994 and January 2011. The primary outcomes included initial success rates and duration of hemostasis after endoscopic management (band ligation vs. injectionsclerotherapy). RESULTS The mean age was 6.7±5.2 years and the mean follow-up time was 5.4±3.7 years. The most common cause of esophageal varices was biliary atresia. Of 55 children with acute variceal bleeding, 39 had band ligation and 16 had injection sclerotherapy. No differences between groups were observed in terms of the size, location, and presence of red color sign. The success rates of band ligation and sclerotherapy in the control of acute bleeding episodes were 89.7% and 87.5%. The mean duration of hemostasis after endoscopic intervention was 13.2±25.1 months. After one year, 19 of 39 patients (48.7%) treated with band ligation and 7 of 16 patients (43.8%) with injection sclerotherapy had experienced rebleeding episodes. Complications after the procedures were observed in 10.3% and 18.8% of children treated with band ligation and injection sclerotherapy. CONCLUSION The results of our current study suggest that band ligation and injection sclerotherapy are equally efficient treatments for the control of acute variceal bleeding and prevention of rebleeding.

Abstract
Variceal bleeding results in significant morbidity and mortality in both children and adults. The guidelines for the management of variceal bleeding are well established in adults but not in children as there have been insufficient pediatric studies of this disorder. In addition, the adult guidelines for treatment of variceal bleeding cannot be applied directly to children as the etiology and natural course of this disease differs between children and adults. Examples of recommended treatments in children include endoscopic variceal ligation as secondary prophylaxis for biliary atresia whereas a meso-Rex shunt operation for extrahepatic portal vein obstruction. In this review, we discuss prophylaxis options and some technical aspects of endoscopic management for variceal bleeding in children.

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
INTRODUCTION Extrahepatic portal vein obstruction is an important cause of portal hypertension among children. The etiology is heterogeneous and there are few evidences related to the optimal treatment. AIM AND METHODS To establish guidelines for the diagnosis and treatment of EHPVO in children, a group of gastroenterologists and pediatric surgery experts reviewed and analyzed data reported in the literature and issued evidence-based recommendations. RESULTS Pediatric EHPVO is idiopathic in most of the cases. Digestive hemorrhage and/or hypersplenism are the main symptoms. Doppler ultrasound is a non-invasive technique with a high degree of accuracy for the diagnosis. Morbidity is related to variceal bleeding, recurrent thrombosis, portal biliopathy and hypersplenism. Endoscopic therapy is effective in controlling acute variceal hemorrhage and it seems that vasoactive drug therapy can be helpful. For primary prophylaxis of variceal bleeding, there are insufficient data for the use of beta blockers or endoscopic therapy. For secondary prophylaxis, sclerotherapy or variceal band ligation is effective; there is scare evidence to recommend beta-blockers. Surgery shunt is indicated in children with variceal bleeding who fail endoscopic therapy and for symptomatic hypersplenism; spleno-renal or meso-ilio-cava shunting is the alternative when Mesorex bypass is not feasible due to anatomic problems or in centers with no experience. CONCLUSIONS Prospective control studies are required for a better knowledge of the natural history of EHPVO, etiology identification including prothrombotic states, efficacy of beta-blockers and comparison with endoscopic therapy on primary and secondary prophylaxis.

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
BACKGROUND AND AIM There is scarcity of data about children on a combination of endoscopic variceal ligation (EVL) and endoscopic sclerotherapy (EST). We assessed the efficacy of EVL followed by EST and EST alone in children with extrahepatic portal venous obstruction (EHPVO). METHODS From January 2000 to March 2007, 186 consecutive children (mean age 6.3 ± 4.2 years, 82% boys) with EHPVO with variceal bleeding were included. EVL followed by EST (Group I, n = 101) or EST alone (Group II, n = 60) was carried out at 3-weekly intervals until eradication. Surveillance endoscopy was done at 3 to 6-monthly intervals. In all cases, the number of sessions required to eradicate the esophageal varices, the volume of sclerosant, the complications and the endoscopic outcome on follow up were recorded. RESULTS Eradication was achieved in 158 of 161 (98%) children and 25 were lost to follow up. Group I required significantly fewer sessions (5.2 ± 1.8 vs 6.8 ± 2.8, P < 0.005), less sclerosant (13 ± 8.2 mL vs 30 ± 20 mL, P < 0.001) and had fewer complications (7% vs 28%, P < 0.001) as compared with Group II. On follow up (33 ± 17.6 months in Group I and 43 ± 16.7 months in Group II), there was a significant increase in the prevalence of portal hypertensive gastropathy as well as isolated gastric varices in both the groups. However, the prevalence of gastroesophageal varices decreased. CONCLUSIONS EVL followed by EST is better than EST alone in children with EHPVO as it requires fewer sessions and has fewer complications. However, following eradication, evolution of gastric varices and portal hypertensive gastropathy was similar in the two groups.

Abstract
Management of portal hypertension in children has evolved over the past several decades. Portal hypertension can result from intrahepatic or extrahepatic causes. Management should be tailored to the child based on the etiology of the portal hypertension and on the functionality of the liver. The most serious complication of portal hypertension is gastroesophageal variceal bleeding, which has a mortality of up to 30%. Initial treatment of bleeding focuses on stabilizing the patient. Further treatment measures may include endoscopic, medical, or surgical interventions as appropriate for the child, depending on the cause of the portal hypertension. β-Blockers have not been proven to effectively prevent primary or secondary variceal bleeding in children. Sclerotherapy and variceal band ligation can be used to stop active bleeding and can prevent bleeding from occurring. Transjugular intrahepatic portosystemic shunts and surgical shunts may be reserved for those who are not candidates for transplant or have refractory bleeding despite medical or endoscopic treatment.

Abstract
OBJECTIVES There are no studies on health-related quality of life (HRQOL) in children with extrahepatic portal venous obstruction (EHPVO). The present study evaluated the QOL in children with EHPVO, prevariceal and postvariceal esophageal variceal eradication, and postsurgery in comparison with healthy controls. METHODS Children with EHPVO and variceal bleeding were divided into 3 groups: group A, before variceal eradication (n = 50); group B, after variceal eradication (n = 50); and group C, after surgery (n = 12). Group D comprised healthy children (n = 50). Clinical details and investigations were recorded. The Pediatric Quality of Life Inventory parent-proxy HRQOL questionnaire was used for assessment of QOL. RESULTS Compared with controls, patients with EHPVO in groups A, B, and C had lower median QOL scores in physical, emotional, social, and school functioning health domains. Esophageal variceal eradication had no significant effect on QOL (median total QOL score pre- and postvariceal eradication of 87.5 vs 86.3). Increasing size of spleen (mild 92.5, moderate 88.2, and severe 76.2; P < 0.001), presence of hypersplenism (90 vs 73.7, P = 0.001), and growth retardation (90 vs 82.5, P = 0.04) caused significant reduction of the total QOL score. On multivariate regression analysis, splenic size and growth retardation were found to be independent predictors that affect the QOL. After surgery, a trend toward improvement in physical, psychosocial, and total QOL scores was present, but it was not significant. CONCLUSIONS Children with EHPVO have a poor QOL that is not affected by variceal eradication. Splenomegaly and growth retardation significantly affect the HRQOL. A trend toward improvement of QOL scores is observed in the postsurgery group.

Abstract
BACKGROUND Long-term follow-up studies of patients with extrahepatic portal venous obstruction (EHPVO) after eradication of esophageal varices using endoscopic sclerotherapy (EST) are limited. METHODS Between 1985 and 1994, 223 patients with bleeding esophageal varices due to EHPVO underwent variceal eradication using EST. Regular annual clinical and endoscopic follow-up data were available for 198 of these patients for a mean period of 19.8 (range: 14-23) years. These data were analyzed retrospectively. RESULTS Of the 198 patients, 34 (17.2%) had rebleeding after variceal eradication. The mean duration from variceal eradication to recurrence of bleeding was 5.4 years. The causes of rebleeding were: recurrent esophageal varices in 21 patients, fundal varices in eight, portal gastropathy in three, and ectopic varices in two patients. Esophageal varices reappeared in 39 (19.7%) patients. Fundal varices appeared in 19 (9.5%) patients during follow-up. CONCLUSIONS EST is an effective treatment modality for bleeding esophageal varices due to EHPVO. During a follow-up of nearly 20 years after variceal eradication, only about one-sixth of the patients had recurrence of gastrointestinal bleeding. Bleeding was unusual after 10 years had passed since initial variceal eradication.

Abstract
BACKGROUND AND AIM Information about portal hypertension (PHT) in children is meagre. We therefore studied the spectrum and outcome of PHT in children (<or=14 years of age) over a period of 9 years. METHODS PHT was diagnosed on endoscopy (presence of varices) in 517 cases during the study period. The diagnosis of extrahepatic portal venous obstruction (EHPVO) and Budd-Chiari Syndrome (BCS) were made on the basis of ultrasound examination. Cirrhosis was diagnosed on the basis of clinical, biochemical, ultrasound, and liver biopsy (whenever feasible). Noncirrhotic portal fibrosis (NCPF) and congenital hepatic fibrosis (CHF) were diagnosed on liver biopsy. Endoscopic sclerotherapy (EST) was done in all the patients who presented with variceal bleeding and surgery was performed whenever indicated. RESULTS Causes of PHT included EHPVO in 54%, cirrhosis in 39%, CHF in 3%, NCPF in 2%, and BCS in 2%. Of these, 279 (54%) patients presented with upper gastrointestinal bleeding and this group comprised of EHPVO in 85%, cirrhosis in 10%, CHF in 2.5%, NCPF in 2%, and BCS in 1%. Bleeding was the presenting feature in 85% of EHPVO cases and in 13% of cirrhosis cases. In EHPVO cases, variceal eradication was achieved in 95% of cases with a mean 5 +/- 2.4 EST sessions. Surgery was required in 24 cases of EHPVO. Mortality due to bleeding was 1.7% in EHPVO and 30% in cirrhosis. CONCLUSIONS EHPVO and cirrhosis are the two major causes of PHT in children. However, predominant cause of variceal bleeding is EHPVO. EST is an effective method of treatment in EHPVO.

Abstract
The meso-Rex bypass procedure has been used to treat patients with portal hypertension from extrahepatic portal vein obstruction. This report describes modifications of this procedure in 5 patients. Either the splenic or coronary vein was used as the venous inflow point, and the bypass was performed either directly through transposition of the vein or with the use of a venous conduit.

Abstract
OBJECTIVES To find out the recurrence of esophageal varices, evolution of gastric varices, portal hypertensive gastropathy (PHG) and risk of rebleeding following esophageal variceal eradication. METHODS Between 1992 and 2002, children with extrahepatic portal venous obstruction (EHPVO) and bleeding from esophageal varices received endoscopic injection sclerotherapy until eradication. Surveillance endoscopy was performed initially at 3 months and subsequently at intervals of 6 months to one year to detect esophageal and gastric varices, and PHG. Gastric varices were classified as gastroesophageal (GOV) or isolated gastric varices (IGV). Gastroesophageal varices included types GOV1 and GOV2 that extend along lesser and greater curvatures respectively. Patients who had recurrence of bleeding were evaluated by emergency upper gastrointestinal endoscopy. RESULTS 163 of 183 children who achieved esophageal variceal eradication were evaluated. Esophageal varices recurred in 40% cases. Primary gastric varices (before sclerotherapy) were seen in 61% cases [GOV 98% (83% GOV1, 15% GOV2) and IGV 2%] and secondary (after sclerotherapy) in 28% [GOV 71% (47% GOV1, 24% GOV2) and IGV 29%]. Secondary gastric varices were distributed as 20% GOV1, 42% GOV2 and 87% IGV. Frequency of gastric varices before sclerotherapy and at the last follow up showed decrease in GOV1 from 82 to 56 (P = 0.02), increase in GOV2 from 15 to 23 and increase in IGV from 2 to 15 (P < 0.001). PHG increased in frequency from 12% to 41% (P < 0.001) and severity from one patient to 12 (P < 0.001). Eleven cases had rebleeding from gastric varices (5 GOV1, 4 GOV2 and 2 IGV). CONCLUSIONS Following esophageal variceal eradication in children with EHPVO a significant decrease in GOV1, increase in IGV and increased frequency and severity of PHG takes place. Small rebleeding risk persists from gastric varices irrespective of the type.

Abstract
Extra-hepatic portal hypertension (EHPH) defined as non cirrhotic, presinusoidal and prehepatic portal hypertension, with obstruction and cavernomatous transformation of the main portal vein, entails a high, early and prolonged risk of gastro-intestinal bleeding (GIB) mainly from esophageal and/or gastric varices, and less often a risk of cholangiopathy or protein-losing enteropathy. Diagnosis of EHPH may be done with non invasive imaging techniques. Assessment of bleeding risk is based on results of endoscopic examination. Occurence of a bleeding episode or onset during follow-up of endoscopic signs of high risk of GIB require radical eradication of varices. Radical cure of EHPH is achieved at best by bypass surgery restoring a physiological portal flow, and as a second choice by shunt surgery. Endoscopic therapy has a place as first line treatment of GIB episodes, and also in a few cases with poor extrahepatic portal network contra-indicating efficient vascular surgery.

Abstract
Although endoscopic band ligation (EVL) plus sclerotherapy (EST) has shown to be superior to any individual method, there is no study in children. We therefore analyzed our experience of EST and EVL + EST in children with extrahepatic portal venous obstruction (EHPVO). Over a period of 8 years, 136 children who presented with a history of recent variceal bleeding due to EHPVO were studied; 30 of them received EVL + EST and 106 received EST alone. In the EVL + EST group, after the first session of EVL, EST was done three times weekly until variceal eradication was achieved. The mean age of these children was 7 +/- 3.6 years with a male-to-female ratio of 2.6:1. The rate of eradication was comparable in both groups (100% in EVL + EST and 96% in EST). However, EVL + EST group required a significantly fewer sessions and lower volume of sclerosant (2 +/- 1 vs. 4.4 +/- 2 sessions, P < 0.001 and 3.1 +/- 2 mL versus 7.5 +/- 4 mL, P < 0.001 respectively). There were significantly less complications in EVL + EST group (10% vs. 36%, P < 0.01). Over a mean follow-up of 27 months, varices recurred in 6.6% and 10% cases, respectively. EVL + EST is a better method in the treatment of esophageal varices in children with EHPVO than EST alone, as it required fewer session and had fewer complication.

Abstract
BACKGROUND Several studies carried out to examine the growth of children with extra-hepatic portal vein obstruction and portal hypertension have reported a variety of findings. AIM To assess anthropometric indices in children with portal hypertension due to extra-hepatic portal vein obstruction and who were treated by endoscopic variceal sclerotherapy. METHODS Anthropometric data were obtained retrospectively from the medical records of 24 patients who had been followed for 3.8 +/- 2.5 years at the Pediatric Gastroenterology Outpatient Clinic of the University Hospital, Campinas, SP, Brazil. The mean Z scores of weight for age, height for age and body mass index at diagnosis and at the last consultation were compared to reference data of the National Center for Health Statistics. The two recordings were compared to assess the long-term effect of the condition. RESULTS The mean Z scores at diagnosis and at the last follow-up visit were all within normal ranges when compared to the reference population, with the following respective values: weight for age, 0.042 +/- 1.09 and 0.132 +/- 1.29; height for age, 0.200 +/- 1.04 and 0.466 +/- 1.24, and body mass index, -0.223 +/- 0.98 and -0.198 +/- 0.98. In addition, there were no significant differences between the Z score values obtained in the two recordings. CONCLUSION Portal hypertension due to extra-hepatic portal vein obstruction was not associated with growth impairment in the group of children studied.

Abstract
OBJECTIVE Mortality of extrahepatic portal vein thrombosis depends on underlying causes other than gastrointestinal bleeding. The aim of this study was to evaluate the etiology, treatment, and prognosis of patients with extrahepatic portal vein thrombosis. METHODS The records of 12 patients (age range: 1-9 years) diagnosed with extrahepatic portal vein thrombosis with a minimum follow-up of 2 years were analyzed retrospectively. Their diagnostic evaluations, treatment modalities, complications and long-term follow-ups were noted. RESULTS Mean follow-up period was 7.4 +/- 3.9 years (2-14 years). Hemorrhage from esophageal varices was the prevalent symptom in 6 patients (50%). Six patients had signs of hypersplenism, 5 were found to have thrombophilia: 2 protein C, 1 protein S, 1 combined protein S, C, and antithrombin III deficiency, and 1 homozygous factor V Leiden mutation. Two patients had congenital cardiovascular abnormalities, and 1 patient developed portal thrombosis after splenectomy operation. None of the patients who started propranolol prophylaxis before first bleeding episode bled during their follow-up periods. Endoscopic sclerotherapy succeed in 66.6% variceal hemorrhages. Shunt surgery was performed in 1 patient. The patients neither faced a life-threatening variceal bleeding nor died during follow-up period. CONCLUSION Prognosis of extrahepatic portal vein thrombosis is good in childhood. Thrombophilic states are the most frequent precipitating causes. Propranolol for prophylaxis of variceal bleeding and sclerotherapy might be the preferred modalities.

Abstract
BACKGROUND Esophageal variceal bleeding is a life-threatening complication of portal hypertension. Optimal treatment for the prophylaxis of variceal rebleeding in children has not yet been determined. In the present study, we aimed to compare the long-term efficacy of endoscopic sclerotherapy with or without oral beta-blocker therapy in the secondary prophylaxis of variceal bleeding. METHODS Thirty-eight children who had undergone endoscopic sclerotherapy (EST) sessions for variceal bleeding in the Department of Pediatric Gastroenterology, Istanbul University Istanbul School of Medicine, were entered into this retrospective cohort study. Twenty patients (mean +/- SD age 7.0 +/- 2.7 years) had undergone only sclerotherapy sessions (SG), whereas 18 patients (mean age 6.8 +/- 3.4 years) had received oral propranolol (1-2 mg/kg per day) additionally for 2 years (SPG). The number of patients with successful obliteration, the time required for obliteration and variceal recurrence rate were analyzed as primary indicators of the effectiveness of therapy. RESULTS Variceal obliteration was achieved in 16 of 20 patients (80%) in the SG group and in 16 of 18 patients (88%) in the SPG group. Time required for variceal obliteration was significantly shorter in the SPG group compared with the SG group (4.1 +/- 1.4 vs 3.2 +/- 0.9 months; P < 0.05). The variceal recurrence rate was 65 and 38.8% in the SG and SPG groups, respectively. Compared with the SG group, less variceal rebleeding was observed during EST in the SPG group (25 vs 16.6%, respectively).However, these differences were not statistically significant. CONCLUSIONS Endoscopic sclerotherapy combined with oral propranolol treatment shortens the time required for variceal obliteration. However, the other indicators of treatment effectiveness are not influenced statistically by the addition of propranolol to the treatment regimen. Randomized prospective clinical studies in larger pediatric series are needed before offering a combination of EST with oral propranolol as the most rational approach in the secondary treatment of esophageal variceal bleeding in children.

Abstract
BACKGROUND Endoscopic sclerotherapy often is used to treat variceal bleeding in children with extrahepatic portal hypertension, but published data are limited. The role of endoscopic sclerotherapy in a large number of children with extrahepatic portal hypertension was evaluated. METHODS Consecutive children presenting with variceal bleeding because of extrahepatic portal hypertension were included in this study. All children underwent endoscopic sclerotherapy with absolute alcohol at presentation and at 2-week to 3-week intervals thereafter, until variceal eradication was achieved. Follow-up endoscopy was performed at 3 months after eradication and then every 6 months thereafter. RESULTS A total of 257 patients with extrahepatic portal hypertension were managed from January 1992 to December 2001. Of these, 50 were lost to follow-up before eradication was achieved, leaving 207 patients (144 boys, 63 girls; mean age at presentation, 7 [SD 3.5] years) for whom evaluation was complete. Of the 207 patients, 5 died of bleeding, 23 underwent surgery, and 6 are still undergoing endoscopic treatment. Varices were successfully eradicated in 165 of 173 cases (95%) after a mean of 4.5 (1.9) endoscopic sclerotherapy sessions (mean volume of sclerosant, 8 [4] mL). Complications encountered were ulcer (17%), stricture (18%), and perforation (1.4%). Interval bleeding before eradication was encountered in 10.6% of cases. At a mean follow-up of 36 (29) months, varices had recurred in 17% patients, but only 3 of them had recurrent bleeding. CONCLUSIONS Endoscopic sclerotherapy effectively eradicates varices in children with extrahepatic portal hypertension, with an acceptable complication rate. On long-term follow-up, recurrent bleeding after eradication is rare.

Abstract
BACKGROUND AND AIM Differentiation between cirrhosis and extrahepatic portal venous obstruction (EHPVO) in children presenting with features of portal hypertension is important for cost-effective management and proper resource utilization. We undertook this study to differentiate clinical and laboratory features between these two groups of patients. METHODS Clinical features and laboratory parameters at presentation of children with portal hypertension and cirrhosis of the liver were analyzed. The variables analyzed were age at presentation, duration of symptoms, incidence and frequency of upper gastrointestinal (GI) bleeding, encephalopathy, jaundice, ascites, splenomegaly, and presence of dilated abdominal veins. The laboratory parameters studied were hemoglobin, prothrombin time, serum bilirubin, albumin, aspartate aminotransferase, alanine aminotransferase and alkaline phosphatase. Two groups were compared using appropriate statistical methods; and the differentiating features were analyzed using logistic regression analysis. RESULTS Of the total of 120 cases, cirrhosis was diagnosed in 28.3% and EHPVO in 71.6%. Children with EHPVO, in comparison to cirrhosis, had significantly higher frequency of upper GI bleeding (61.6%vs 14.7%), increased number of previous bleeding episodes (2.7 +/- 0.5 vs 1.2 +/- 0.4), longer duration of symptoms (25.7 +/- 4.6 vs 12.3 +/- 3 months) and a lower frequency of jaundice (2%vs 76.4%). Low hemoglobin (6.4 +/- 2.7 g/dL) and preserved liver functions characterized by normal bilirubin, albumin levels and prothrombin time were observed in EHPVO cases. Cirrhosis patients had higher hemoglobin (8.8 +/- 2.8 g/dL) and abnormal liver function tests. CONCLUSION Presence of UGI bleeding and the absence of jaundice are 97.5% accurate in predicting diagnosis of EHPVO.

Abstract
Portal hypertension (PHT) is common in children and a majority of cases in India are constituted by extrahepatic portal venous obstruction or cirrhosis of liver. Morbidity and mortality in this condition is related to variceal bleeding, most commonly from esophageal varices. Acute variceal bleeding is best controlled by endoscopic therapy. Somatostatin and octreotide are useful in acute variceal bleeding as a supplementary therapy. Acute variceal bleeding uncontrolled by medical therapy merits preferably a shunt surgery or devascularization depending upon etiology of PHT and expertise of the surgeon. Acute variceal bleeding originating from gastric varices can be effectively controlled by endoscopic injection of tissue adhesive agent (n-butyl 2 cyanoacrylate). Eradication of esophageal varices by endoscopic measures (sclerotherapy or band ligation) is successful in prevention of recurrence of bleeding. Surgical portosystemic shunts especially in non-cirrhotic PHT are successful in achieving portal decompression and significant reduction in recurrence of variceal bleeding. Role of beta-blockers in primary prophylaxis of variceal bleeding in children still remains to be substantiated.

Abstract
BACKGROUND Variceal bleeding from the esophagus is an important cause of mortality and morbidity in children with portal hypertension (PHT). PATIENTS AND METHODS A series of 69 PHT cases (41 intrahepatic, 28 extrahepatic) have been evaluated in our department since 1990. According to the Child-Pugh classification, 49 cases were in class A, 16 cases were in class B, and 4 cases were in class C at admission. In our protocol, endoscopic sclerotherapy is performed in all patients, and the diagnosis is achieved directly by diagnostic laparoscopy and fine-needle liver biopsy. The procedure is applied under general anesthesia, and 1% aethoxysclerol (polidocanol) is injected paravariceally and intravariceally with the use of a flexible endoscope. RESULTS The Sugiura procedure was performed in nine patients who presented with recurrent bleeding episodes despite the strict sclerotherapy protocol. Liver transplantation was performed in two patients who were in Child class C. The total mortality rate in this series was 7% (5/69). CONCLUSION Endoscopic sclerotherapy, as presented herein, decreases the need for additional surgical interventions in children with PHT.

Abstract
Therapeutic options for children with portal hypertension now include a broad range of pharmacologic, endoscopic, and surgical procedures. Thoughtful application of all of these options can improve quality of life by decreasing the complications of portal hypertension and can decrease mortality by preventing the consequences of variceal hemorrhage. The development of portal hypertensive gastropathy following palliative procedures such as endoscopic sclerotherapy and band ligation may limit their long-term success in children. The excellent results now obtained with selective portosystemic shunts and liver transplantation assure that definitive surgical treatments will continue to be important components in the treatment of children with portal hypertensive complications or progressive liver disease. Evolving procedures, such as TIPS, represent excellent short-term life-preserving techniques to stabilize critically ill patients while awaiting liver transplantation. Their role in the future, long-term management of children is yet to be defined.

Abstract
BACKGROUND Surgical portosystemic shunting has been performed less frequently in recent years. In this retrospective study, recent outcomes of portosystemic shunting in children are described, to evaluate its role in the era of endoscopic therapy. METHODS Retrospective chart review of children who underwent surgical portosystemic shunt procedures between October 1994 and October 1997. RESULTS Twelve children (age range, 1-16 years) underwent shunting procedures. The causes of portal hypertension were extrahepatic portal vein thrombosis (n = 6), congenital hepatic fibrosis (n = 2), hepatic cirrhosis (n = 2), and other (n = 2). None of the patients were immediate candidates for liver transplantation. Types of shunt included: distal splenorenal (n = 10), portocaval (n = 1), and other (n = 1). Median follow-up was 35 months (range, 24-48 months). All patients are currently alive and well with patent shunts. The mean hospital stay was 8 days. Three patients required readmission for further interventions because of shunt stenosis in two and small bowel obstruction in the other. Mild portosystemic encephalopathy was seen in one child with pre-existing neurobehavioral disturbance. Excluding a patient who underwent placement of a portosystemic shunt for a complication of liver transplantation, mean weight-for-age z score in nine prepubertal patients improved from -1.16 SD to +0.15 SD (P = 0.023), and mean height-for-age z score from -1.23 SD to 0.00 SD (P = 0.048) by 2 years after surgery. CONCLUSIONS Surgical portosystemic shunting is a safe and effective method for the management of portal hypertension in childhood. Patients show significant improvements in growth parameters after the procedure. Surgical portosystemic shunting should be actively considered in selected children with portal hypertension.

Abstract
Gastrointestinal (GI) bleeding is an alarming problem in children. Although many causes of GI bleeding are common to children and adults, the frequency of specific causes differs greatly, and some lesions, such as necrotizing enterocolitis or allergic colitis, are unique to children. This article reviews the spectrum of GI bleeding in infants and children. The causes, diagnostic evaluation, and management are discussed, and differences with adult medicine are highlighted.

Abstract
BACKGROUND/PURPOSE Extrahepatic portal vein thrombosis (EPVT) in children can lead to severe bleeding from gastrointestinal varices, ascites, thrombocytopenia from hypersplenism, and other coagulation disorders. The authors have used the superior mesenteric vein to intrahepatic left portal vein (Rex) shunt in 5 children with symptomatic EPVT and report their results with this novel technique. METHODS Children with symptomatic portal hypertension were screened for the underlying cause. All children with essentially normal livers and obstruction of the extrahepatic portal vein were considered for the Rex shunt. Evaluation included liver function tests, liver biopsy, and radiological evaluation of the intrahepatic vascular anatomy. RESULTS Five patients between the ages of 2.8 and 10.5 years underwent evaluation for portal hypertension secondary to extrahepatic portal vein obstruction. Three patients had idiopathic extra hepatic portal vein thrombosis with cavernous transformation, 1 had thrombosis after a living-related liver transplant, and 1 had compression and obstruction of the main portal vein from enlarged lymph nodes after treatment of systemic histoplasmosis. All patients were symptomatic. Three patients had intermittent bleeding from esophageal and gastric varices, and all 5 had relative degrees of hypersplenism with enlarged spleens and thrombocytopenia (11,000 to 77,000). Three patients had significant leukopenia. Results of imaging studies suggested that 3 patients had inadequate intrahepatic portal veins for shunting, but all patients at exploration underwent successful shunting. There were no serious intraoperative complications. Postoperative complications included ascites in 2 patients that resolved within 1 month. There were no early shunt thromboses. The median postoperative length of stay was 7 days. Clinical follow-up ranged from 7 to 21 months. Gastrointestinal bleeding did not recur in any patient, and ascites resolved in all. Spleen size decreased significantly (P < .01) from 9.4 +/- 4.0 cm to 5.0 +/- 3.7 cm below the left costal margin. Mean platelet count and white blood cell count rose after shunting from 79 +/- 42 to 176 +/- 73 (P < .02) and 5.4 +/- 2.3 to 7.5 +/- 3.9 (P = .06), respectively. All shunts were studied at 1 and 7 days, and 3 and 6 months after the procedure. Shunt patency was documented in all cases. Subsequently, shunt blockage occurred in 2 patients. CONCLUSIONS The Rex shunt has proven to be an effective method of resolving portal hypertension caused by EPVT including thrombosis after living donor transplantation. This shunt is preferable to other surgical procedures because it eliminates portal hypertension and its sequelae by restoring normal portal flow to the liver.

Abstract
The treatment of esophageal variceal hemorrhage is still the subject of some controversy. The main causes of portal hypertension in children are portal vein thrombosis or cirrhosis, most commonly caused by biliary atresia. Many treatment options are available including endoscopic, radiographic, and surgical strategies. In general, children with presinusoidal obstructions have preserved hepatic synthetic function, and, therefore, treatment options include endoscopic strategies or portosystemic shunts, each with advocates. For children with advanced liver disease, liver transplantation offers the only chance for cure, so primary treatment of variceal bleeding should be by endoscopic means or transjugular intrahepatic portosystemic shunt (TIPS). Each modality has specific advantages and disadvantages, and treatment recommendations must therefore be tailored to the individual on a case-by-case basis, largely dependent on the expertise and experience of the health care team.

Abstract
Exclusive human milk feeding during the first 6 months of life, with delayed introduction of solids, is the recommended feeding for human infants. Human milk reduces the incidence and morbidity related to infection and allergy to cow's milk proteins. Dietary maternal restrictions during (late) pregnancy or lactation cannot be recommended, but may be advised in special cases. A maternal elimination diet seems more effective if associated with environmental hypoallergenic intervention(s). Milk from mothers consuming cow's milk proteins contains small amounts of beta-lactoglobulin, which appear to introduce in the majority of infants both atopic and non-atopic tolerance rather than sensitization. However, it is uncertain whether breastfeeding also reduces the incidence of later atopic disease, since its aetiology is multifactorial.
