Abstract
PURPOSE To review surgical management of extrahepatic portal vein obstruction (EHPVO) at Red Cross War Memorial Children's Hospital and compare MesoRex shunt (MRS) with distal splenorenal shunt (DSRS). METHODS This is a single-centre retrospective review documenting pre- and post-operative data in 21 children. Twenty-two shunts were performed, 15 MRS and 7 DSRS, over an 18-year period. Patients were followed up for a mean of 11 years (range 2-18). Data analysis included demographics, albumin, prothrombin time (PT), partial thromboplastin time (PTT), International normalised ratio (INR), fibrinogen, total bilirubin, liver enzymes and platelets before the operation and 2 years after shunt surgery. RESULTS One MRS thrombosed immediately post-surgery and the child was salvaged with DSRS. Variceal bleeding was controlled in both groups. Significant improvements were seen amongst MRS cohort in serum albumin, PT, PTT, and platelets and there was a mild improvement in serum fibrinogen. The DSRS cohort showed only a significant improvement in the platelet count. Neonatal umbilic vein catheterization (UVC) was a major risk for Rex vein obliteration. CONCLUSION In EHPVO, MRS is superior to DSRS and improves liver synthetic function. DSRS does control variceal bleeding but should only be considered when MRS is not technically feasible or as a salvage procedure when MRS fails.

Abstract
Liver diseases are a major cause of illness and death worldwide. In China, liver diseases, primarily viral hepatitis, affect approximately 300 million people, thus having a major impact on the global burden of liver diseases. Portal hypertension is the most severe complication of chronic liver diseases, including ascites, hepatic encephalopathy and bleeding from gastroesophageal varices. Transjugular intrahepatic portosystemic shunt (TIPS) represents a very effective treatment of these complications. Since its introduction 30 years ago in China, the use of TIPS has evolved and has played an increasingly important role in the management of the complications of portal hypertension. This review will focus on the history, current application and management of complications of TIPS in China.

Rex Shunt for Extra-Hepatic Portal Venous Obstruction in Children. CHILDREN 2022; 9:children9020297. [PMID: 35205017 PMCID: PMC8870553 DOI: 10.3390/children9020297] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/28/2022] [Revised: 02/14/2022] [Accepted: 02/18/2022] [Indexed: 01/02/2023]
Abstract
Rex shunt, which was first put in use in 1992, has been considered as an ideal surgical method for the treatment of extra-hepatic portal venous obstruction (EHPVO) due to its reconstruction of the hepatopetal portal blood flow. However, despite its long tradition, there are only a few reports about the application and advances in Rex shunt for the treatment of EHPVO in children. In this paper, we summarized the literature related to Rex shunt and discussed the new advances of Rex shunt in the following aspects: surgical method of Rex shunt, the indications of Rex shunt, the strengths of Rex shunt, the effectiveness of Rex shunt, factors affecting the efficacy of Rex shunt, methods that improve the prognosis of Rex shunt, and treatment strategy for recurrence after Rex shunt.

Abstract
BACKGROUND AND AIM Shunt surgery is the definitive treatment for symptomatic patients with portal cavernoma cholangiopathy (PCC), but few patients are non-surgical candidates or fail to improve even after surgery. This study aims to analyze the long-term outcomes of endoscopic therapy in these patients. METHODS Retrospective review of a prospectively maintained database of all patients with symptomatic PCC managed with endoscopic retrograde cholangiography (ERC) followed by stent placement. Outcomes studied included number of biliary interventions, complications, resolution of stricture, development of decompensation and mortality. RESULTS Thirty-five patients (68.6% males, median age = 35 years) with a median follow-up duration of 46 months (12-112) were included in the analysis. Presentation was only jaundice in 51.4% cases while one-third (37.1%) of the patients presented with cholangitis. Patients underwent a total of 363 endoscopic sessions with a median of 9 procedures (3-29) per patient. Hemobilia was the most common complication of the procedure (6.06%). Ten (28.5%) patients required frequent stent exchanges. Patients who required frequent stent exchanges had higher number of cholangitis episodes and hospitalization. Secondary biliary cirrhosis developed in 4 (11.4%) patients and 2 (5.7%) patients had mortality. Of the 5 (14.3%) patients who were given a stent free trial, 3 patients required restenting due to redevelopment of symptoms. CONCLUSION Patients with PCC without shuntable veins for surgery or those who failed to improve after surgery can be managed long-term with repeated endoscopic intervention with a slightly increased risk of non-fatal hemobilia.

Abstract
PURPOSE Extrahepatic portal vein obstruction (EHPVO) is a major cause of non-cirrhotic portal hypertension in children. Surgical procedures for EHPVO include portosystemic shunts (PSS) and meso-Rex bypass (MRB). We conducted a systematic review and meta-analysis to compare the effectiveness of MRB versus PSS in EHPVO patients. METHODS A systematic literature search was performed using four databases. Articles reporting EHPVO and comparing patients who received MRB and PSS were included in the analysis. RESULTS We retrieved 851 papers, of which five observational studies met the inclusion criteria. There was no difference in shunt complications, mortality, or gastrointestinal bleeding after surgery between MRB and PSS in the meta-analysis. MRB had increased shunt complications compared with PSS in the non-comparative studies. MRB had a potential advantage over PSS in long-term prognosis in one comparative study. Overall, the quality of the evidence was low. CONCLUSIONS Based on available data, our meta-analysis indicates that MRB does not increase shunt complications, mortality, or gastrointestinal bleeding after surgery. The present study did not reveal superiority for either MRB or PSS. The paucity of well conducted trials in this area justifies future multicenter studies and studies that examine long-term outcomes.

Abstract
Non-cirrhotic portal hypertension (NCPH) forms an important subset of portal hypertension in children. Variceal bleed and splenomegaly are their predominant presentation. Laboratory features show cytopenias (hypersplenism) and preserved hepatic synthetic functions. Repeated sessions of endoscopic variceal ligation or endoscopic sclerotherapy eradicate esophageal varices in almost all cases. After variceal eradication, there is an increased risk of other complications like secondary gastric varices, cholangiopathy, colopathy, growth failure, especially in extra-hepatic portal vein obstruction (EHPVO). Massive splenomegaly-related pain and early satiety cause poor quality of life (QoL). Meso-Rex bypass is the definitive therapy when the procedure is anatomically feasible in EHPVO. Other portosystemic shunt surgeries with splenectomy are indicated when patients present late and spleen-related issues predominate. Shunt surgeries prevent rebleed, improve growth and QoL. Non-cirrhotic portal fibrosis (NCPF) is a less common cause of portal hypertension in children in developing nations. Presentation in the second decade, massive splenomegaly and patent portal vein are discriminating features of NCPF. Shunt surgery is required in severe cases when endotherapy is insufficient for the varices. Congenital hepatic fibrosis (CHF) presents with firm palpable liver and splenomegaly. Ductal plate malformation forms the histological hallmark of CHF. CHF is commonly associated with Caroli’s disease, renal cysts, and syndromes associated with neurological defects. Isolated CHF has a favourable prognosis requiring endotherapy. Liver transplantation is required when there is decompensation or recurrent cholangitis, especially in Caroli’s syndrome. Combined liver-kidney transplantation is indicated when both liver and renal issues are present.

Abstract
The clinical outcomes differ between patients with cavernous transformation of the portal vein (CTPV) with and without cirrhosis. Therefore, invasive liver biopsy may be needed for the differential diagnosis of patients with CTPV with or without cirrhosis. The present study aimed to investigate the diagnostic efficacy of liver stiffness measurements (LSM) for the prediction of cirrhosis in patients with CTPV. A total of 20 patients with CTPV, 34 with chronic hepatitis B (CHB)-related cirrhosis and 20 healthy volunteers, were retrospectively recruited in the study. CTPV was diagnosed with contrast-enhanced computed tomography (CT) and ultrasound for the abdomen. LSM values were detected for each patient, while liver biopsy was performed in each patient in the CTPV and cirrhosis groups. The results demonstrated that LSM values were significantly lower in the CTPV group (12.5 kPa; range, 6.8-21.5 kPa) compared with the CHB-related cirrhosis group (21.0 kPa; range, 15.5-27.2 kPa; P=0.017). However, this was still higher compared with healthy volunteers (4.9 kPa; range 4.0-5.8 kPa; P<0.001). In addition, CTPV patients with cirrhosis (17.7 kPa; range, 13.9-30.8 kPa) exhibited significantly increased LSM values compared with those without cirrhosis (6.4 kPa; range, 5.7-7.8 kPa; P<0.001). Furthermore, LSM values in CTPV patients without cirrhosis were slightly higher compared with those of healthy volunteers (P=0.003), while no statistically significant difference was observed in LSM between CTPV patients with cirrhosis and CHB-related cirrhosis group. These findings indicated that LSM values could be used for the differential diagnosis of CTPV patients with or without cirrhosis. However, further validation studies are needed.

Abstract
Background Both noncirrhotic portal fibrosis (NCPF) and extrahepatic portal venous obstruction (EHPVO) are important causes of noncirrhotic portal hypertension (PH) in the Asian region. In this study, we analyzed the histopathological changes of liver needle-core biopsies from patients with NCPF and EHPVO. Patients and Methods The patients were diagnosed as per the Asia Pacific Association for the Study of Liver (APASL) criteria. Minimum adequacy criteria for liver core biopsies were defined, and finally, 69 liver biopsies from patients with NCPF and 100 liver biopsies from patients with EHPVO were analyzed. All histological parameters were predefined, and three experienced pathologists analyzed the biopsies after reaching consensus. Institute ethics committee clearance was taken. Results Although some histological features were overlapping, phlebosclerosis of intra-hepatic branches of the portal vein (PV), periportal aberrant vascular channels, remnant portal tracts, and hepatic fibrosis beyond the portal tracts without the formation of complete hepatic nodules (P < 0.001 for all) were common histological characteristics of NCPF on core-needle liver biopsies; while maintained lobular architecture, nonspecific dilatation of PV branches, absence of intra-hepatic PV phlebosclerosis, aberrant vascular channels, and significant fibrosis were characteristics of EHPVO. Conclusions Despite the considerable histological overlap between NCPF and EHPVO, careful histological evaluation, supplemented by clinical features, radiological and biochemical findings can help in making a conclusive diagnosis. Patients with NCPF and EHPVO with clinical jaundice show transaminitis, high serum alkaline phosphatase level, more variceal bleed, and histological evidences of nodular regenerative hyperplasia.

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
BACKGROUND Ascites in extrahepatic portal venous obstruction (EHPVO) is uncommon. We studied the etiology and natural history of ascites and risk factors of post-bleeding ascites in children with EHPVO. METHODS All admitted EHPVO patients with clinically detectable ascites and/or gastrointestinal (GI) bleeding in previous 6 weeks were analysed. Subjects with ascites were classified as post-bleeding ascites and de-novo ascites (no GI bleeding) Post-bleeding ascites group was compared with controls (GI bleeding without ascites) for risk factors of developing ascites. RESULTS Of the total 307 analysed EHPVO patients, 26% (n=79) had ascites. Majority (n=66, 83%) were post-bleeding ascites and 17% (n=13) had de-novo ascites due to secondary causes. Risk factors of ascites in post-bleeding ascites (n=56) versus controls (n=188) were younger age of disease onset, lower height z-scores and greater reduction in serum protein, albumin and hemoglobin from baseline non-bled state. 32%, 39%, and 29% of patients with post-bleeding ascites had ascites resolution with salt restriction, additional diuretics and large volume paracentesis respectively. CONCLUSIONS Majority of ascites in EHPVO children is after GI bleeding where early age of disease onset, large volume of blood loss and poor nutritional status are risk factors. Overall outcome of EHPVO with ascites is favourable.

Abstract
PURPOSE OF THE REVIEW Non-cirrhotic portal hypertension (NCPH) includes a heterogeneous group of conditions. The aim of this paper is to make an overview on the denominations, diagnostical features and management of porto-sinusoidal vascular disease (PSVD) and chronic portal vein thrombosis (PVT) being the main causes of NCPH in the Western world. RECENT FINDINGS The management of NCPH consists in the treatment of associated diseases and of portal hypertension (PH). PH due to PSVD or PVT is managed similarly to PH due to cirrhosis. TIPS placement and liver transplantation are considerable options in patients with refractory variceal bleeding/ascites and with progressive liver failure. Anticoagulation is a cornerstone both in the treatment of thrombosis in PSVD and in the prevention of thrombosis recurrence in patients with portal cavernoma. Physicians should be aware of the existence of PSVD and chronic PVT and actively search them in particular settings. To now, the management of portal hypertension-related complications in NCPH is the same of those of cirrhosis. Large cooperative studies on the natural history of NCPH are necessary to better define its management.

Abstract
Chronic non cirrhotic extrahepatic portal vein obstruction (EHPVO) refers to the cavernomatous transformation of the portal vein (the so-called "portal cavernoma") which occurs following acute thrombosis of the portal vein in the absence of recanalization. In adults, EHPVO mainly occurs following thrombosis, while in children it may be related to congenital malformations and/or neonatal umbilical venous catheterization. However, 50% of the cases of EHPVO remain idiopathic [1]. Risk factors and associated diseases should be investigated (chapter 1). Indeed, the presence of a thrombophilic alteration, in particular myeloproliferative neoplasm impacts prognosis and determine a causal treatment.

Abstract
BACKGROUND/AIM Chemotherapy is often halted due to abnormal liver function resembling hepatitis. But the cause can be extrahepatic portal venous obstruction (EHPVO) with hepatic enzyme elevation rather than being an adverse effect of chemotherapy. We investigated EHPVO with hepatic enzyme elevation in patients with cancer. PATIENTS AND METHODS Data of these hospitalized patients with solid tumors between January 2013 and September 2017 were collected. The criteria for study inclusion were: (i) Extrahepatic malignancy; (ii) computed tomographic scans showing a tumor with external compression of the extrahepatic portal vein; and (iii) serum aminotransferase (AST) or alanine transaminase (ALT) level three times above the normal value. RESULTS Thirteen out of 377 (3%) patients developed EHPVO with hepatic enzyme elevation, as demonstrated from computed tomographic scan. Four cases (31%) also had vascular thrombosis (three portal vein and one inferior vena cava). Serum AST increased from 34±11 to 169±94 U/l. ALT increased from 9±38 to 177±104 U/l. There was no relationship of EHPVO with viral markers and cirrhosis. Six cases received chemotherapy with liver function improvement. CONCLUSION EHPVO occurred in patients with metastatic cancer, leading to hepatic enzyme elevation resembling hepatitis without hepatitis risk factors and cirrhosis. Before withholding chemotherapy due to hepatic enzyme elevation, the possibility of EHPVO should firstly be excluded.

Abstract
Idiopathic portal hypertension (IPH) and extrahepatic portal venous obstruction (EHPVO) are prototype noncirrhotic causes of portal hypertension (PHT), characterized by normal hepatic venous pressure gradient, variceal bleeds, and moderate to massive splenomegaly with preserved liver synthetic functions. Infections, toxins, and immunologic, prothrombotic and genetic disorders are possible causes in IPH, whereas prothrombotic and local factors around the portal vein lead to EHPVO. Growth failure, portal biliopathy, and minimal hepatic encephalopathy are long-term concerns in EHPVO. Surgical shunts and transjugular intrahepatic portosystemic shunt resolve the complications secondary to PHT. Meso-Rex shunt is now the standard-of-care surgery in children with EHPVO.

Abstract
Budd-Chiari syndrome and non-cirrhotic non-tumoral portal vein thrombosis are 2 rare disorders, with several similarities that are categorized under the term splanchnic vein thrombosis. Both disorders are frequently associated with an underlying prothrombotic disorder. They can cause severe portal hypertension and usually affect young patients, negatively influencing life expectancy when the diagnosis and treatment are not performed at an early stage. Yet, they have specific features that require individual consideration. The current review will focus on the available knowledge on pathophysiology, diagnosis and management of both entities.

Abstract
We report a 12-month-old female infant who had a history of neonatal sepsis with liver micro-abscesses that resolved with intravenous antibiotics during neonatal period. During her neonatal admission period, no umbilical vein catheter was inserted. Also, she did not undergo any abdominal surgeries or had a postnatal history of necrotizing enterocolitis. However, the child developed upper gastrointestinal bleeding in form of hematemesis and melena secondary to esophageal varices at the age of 12 months with an extra-hepatic portal vein obstruction with cavernous transformation and portal hypertension subsequently. The child underwent a successful endoscopic injection sclerotherapy. She is now 20-month-old and has portal hypertension but otherwise asymptomatic. We are proposing the possibility of a delayed-onset portal hypertension as a complication of liver abscess and neonatal sepsis.

Abstract
BACKGROUND Idiopathic portal hypertension (IPH) and extrahepatic portal venous obstruction (EHPVO) are non-cirrhotic vascular causes of portal hypertension (PHT). Variceal bleed and splenomegaly are the commonest presentations. AIM The present review is intended to provide the existing literature on etiopathogenesis, clinical profile, diagnosis, natural history and management of IPH and EHPVO. RESULTS IPH and EHPVO are both characterized by normal hepatic venous pressure gradient, moderate to massive splenomegaly with preserved liver synthetic functions. While the level of block in IPH is presinusoidal, in EHPVO it is at prehepatic level. Infections, autoimmunity, drugs, immunodeficiency and prothrombotic states are possible etiological agents in IPH. Contrastingly in EHPVO, prothrombotic disorders and local factors around the portal vein are the incriminating factors. Diagnosis is often clinical, supported by simple radiological tools. Natural history is defined by episodes of variceal bleed and symptoms related to enlarged spleen. Growth failure, portal biliopathy and minimal hepatic encephalopathy are additional concerns in EHPVO. Long-term survival is reasonably good with endoscopic surveillance; however, parenchymal extinction leading to decompensation is seen in a minority of patients in both the disorders. Surgical shunts revert the complications secondary to PHT. Meso-Rex shunt has become the standard surgery in children with EHPVO. CONCLUSION This review gives a detailed summary of these two vascular conditions of liver-IPH and EHPVO. Further research is needed to understand the pathogenesis and natural history of these disorders.

Abstract
Splanchnic vein thrombosis (SVT) and cerebral vein thrombosis (CVT) are uncommon manifestation of venous thromboembolism (VTE), occurring less frequently than deep vein thrombosis of the lower extremities and pulmonary embolism. SVT encompasses portal vein thrombosis, mesenteric vein thrombosis, splenic vein thrombosis and the Budd-Chiari syndrome. It is therefore a heterogeneous disease, with differences in clinical manifestations according to the site of thrombosis. CVT includes thrombosis of the cortical or deep cerebral veins and thrombosis of the major dural venous sinuses. Clinical presentation is variable, with a wide spectrum of signs and symptoms that can mimic other cerebral diseases. There are no clinical algorithms or specific laboratory tests that can guide in the identification of SVT and CVT; therefore, the diagnosis relies exclusively on imaging tests. Conventional angiography once was the gold standard for the diagnosis of SVT and CVT, but it is rarely used nowadays. Abdominal ultrasound (US), computed tomography (CT) and magnetic resonance (MR) with angiography are currently used for the diagnosis of SVT; while cerebral CT and MR with angiography are currently used for the diagnosis of CVT. These imaging tests have different sensitivities/specificities and different advantages/disadvantages that should be kept into consideration when choosing the appropriate imaging test based on the suspected site of thrombosis. This narrative review summarizes the clinical and diagnostic approach to SVT and CVT.

Abstract
AIMS To evaluate liver stiffness (LS) in patients of primary extrahepatic portal vein obstruction (EHPVO) using 2D shear wave elastography (SWE) and compare it with healthy volunteers. METHODS Fifty patients (mean age: 22.4 years) of EHPVO and 25 healthy volunteers were included in the study. Liver function tests and viral markers were done in both groups and endoscopy in EHPVO group, followed by ultrasonography and SWE of liver. Liver elastography was done with patients/volunteers in supine position through right intercostal space. The LS for right lobe of liver was recorded in kilopascals. Three such measurements were taken and the mean of both groups were compared. The variables were also correlated with mean LS using Pearson's correlation coefficient in EHPVO group. RESULTS There was no significant difference in the mean LS in patients of EHPVO (5.96 kPa) and healthy volunteers (5.47 kPa) (P = 0.093). There was no significant correlation between LS with duration of symptoms, hematemesis, esophageal varices, total bilirubin, serum alkaline phosphatase and aspartate aminotranferase levels in EHPVO group. CONCLUSION SWE of liver may be used as a simple additional tool in the diagnosis of patients of EHPVO who show LS values similar to normal liver.

Abstract
BACKGROUND Minimal hepatic encephalopathy (MHE) is not associated with overt neuropsychiatric symptoms but rather with subtle changes in psychometric and/or neurophysiologic tests. We aimed to diagnose MHE in children with extrahepatic portal vein obstruction (EHPVO) and to evaluate the effect of lactulose on MHE. METHODS A prospective study was carried out on 30 patients with EHPVO (21 males; mean age 10±2.5 years). The study was carried out in the Pediatric Hepatology Unit, Cairo University Pediatric Hospital, Cairo, Egypt, between 2011 and 2013. All patients were subjected to clinical and laboratory assessment, neuropsychmetric testing using the arabic version of Wechsler intelligence tests, neurophysiological testing by visual electroencephalogram and P300 event related potentials (ERP). RESULTS The prevalence of MHE among children with EHPVO was 20% (6/30). After randomization to treatment and no-treatment groups using lactulose, all tests were repeated after three months. Among four patients with MHE who received lactulose, three (75%) improved. On the other hand, one of the patients in the no-treatment group developed MHE. Only one patient in the treatment arm had to discontinue lactulose because of severe diarrhea. CONCLUSIONS This pilot study revealed that the prevalence of MHE was 20%. Improvement on psychometic tests was seen in 75% of our patients (3/4) after treatment with lactulose. Lactulose treatment was well tolerated.

Abstract
Thrombosis of the splenoportal axis not associated with liver cirrhosis or neoplasms is a rare disease whose prevalence ranges from 0.7 to 3.7 per 100,000 inhabitants. However, this entity is the second most common cause of portal hypertension. Prothrombotic factors are present as an underlying cause in up to 70% of patients and local factors in 10-50%. The coexistence of several etiological factors is frequent. Clinical presentation may be acute or chronic (portal cavernomatosis). The acute phase can present as abdominal pain, nausea, vomiting, fever, rectorrhagia, intestinal congestion, and ischemia. In this phase, early initiation of anticoagulation is essential to achieve portal vein recanalization and thus improve patient prognosis. In the chronic phase, symptoms are due to portal hypertension syndrome. In this phase, the aim of treatment is to treat or prevent the complications of portal hypertension. Anticoagulation is reserved to patients with a proven underlying thrombophilic factor.

Abstract
Portal biliopathy (PB) refers to the biliary abnormalities of the biliary ducts observed in patients with extrahepatic portal hypertension. Although majority of patients are asymptomatic, approximately 20% of these patients present with biliary symptoms (pain, pruritus, jaundice, cholangitis). The pathogenesis of PB is uncertain but compression by dilated veins into or around common bile duct may play the main role. CT-scan, MR cholangiopancreatography with MR portography should be the initial investigations in the evaluation of PB. Treatment is limited to symptomatic cases and is dictated by clinical manifestations and complications of the disease. Treatment of PB could be done by endoscopy (sphincterotomy, stone extraction or biliary stenting of the common bile duct) or surgery (definitive decompression by porto-systemic shunt followed by bilioenteric anastomosis, if necessary). This review describes pathogenesis, clinical features, investigation and management of portal biliopathy.

Abstract
Introduction Biliary obstruction is usually caused by choledocholithiasis. However, in some circumstances, alternative or concurring unusual ethiologies such as portal hypertensive biliopathy (PHB) must be considered. Clinical case We present the case of a 36-year-old female complaining of jaundice and pruritus. Liver function tests were compatible with biliary obstruction and the ultrasound scan of the abdomen showed dilatation of the intrahepatic biliary ducts, a dilated common bile duct (CBD) and biliary calculi. The computed tomography of the abdomen revealed a portal cavernoma encasing the CBD. Discussion Portal cavernoma, the hallmark of extrahepatic portal venous obstruction, can cause PHB. When symptomatic, chronic cholestasis is present if a dominant stricture exists whereas biliary pain and acute cholangitis occur when choledocholithiasis prevails. Management must be individualized and usually includes endoscopic therapy to address choledocholithiasis and shunt surgery for definitive treatment.

Abstract
Portal vein thrombosis is an important cause of portal hypertension. PVT occurs in association with cirrhosis or as a result of malignant invasion by hepatocellular carcinoma or even in the absence of associated liver disease. With the current research into its genesis, majority now have an underlying prothrombotic state detectable. Endothelial activation and stagnant portal blood flow also contribute to formation of the thrombus. Acute non-cirrhotic PVT, chronic PVT (EHPVO), and portal vein thrombosis in cirrhosis are the three main variants of portal vein thrombosis with varying etiological factors and variability in presentation and management. Procoagulant state should be actively investigated. Anticoagulation is the mainstay of therapy for acute non-cirrhotic PVT, with supporting evidence for its use in cirrhotic population as well. Chronic PVT (EHPVO) on the other hand requires the management of portal hypertension as such and with role for anticoagulation in the setting of underlying prothrombotic state, however data is awaited in those with no underlying prothrombotic states. TIPS and liver transplant may be feasible even in the setting of PVT however proper selection of candidates and type of surgery is warranted. Thrombolysis and thrombectomy have some role. TARE is a new modality for management of HCC with portal vein invasion.

Abstract
BACKGROUND Portal vein obstruction may be due to portal vein thrombosis (PVT) or its sequale, the portal cavernoma. PVT is a common complication in liver cirrhosis, however, it may also occur as a primary vascular disorder, in absence of any liver disease. AIM To review the current knowledge on nomenclature, etiology, pathophysiology, clinical presentation, diagnostic workup and management of adult patients with obstruction in the portal vein, either as a primary vascular disease in adults, or as a complication of liver cirrhosis. METHODS A structured search in PubMed was performed using defined keywords (portal vein obstruction, extra-hepatic portal vein obstruction, PVT and portal cavernoma), including full text articles and abstracts in English language. RESULTS Several causes, operating both at local and systemic level, might play an important role in the pathogenesis of PVT. Frequently, more than one risk factor could be identified; however, occasionally no single factor is discernible. Diagnosis of portal vein obstruction depends on clinical presentation, imaging and laboratory investigations. Prompt treatment greatly affects the patient's outcome. CONCLUSIONS Portal vein obstruction occurring either due to thrombosis in the portal vein or due to the portal cavernoma, can contribute to significant morbidity and mortality in patients with or without cirrhosis. In recent years our understanding of etio-pathogenesis of portal vein obstruction has evolved tremendously, which has led to significant improvement in treatment outcomes. There are still areas where more studies are needed to better clarify the management issues of portal vein obstruction.

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

Abstract
We retrospectively analyzed the data of 24 children (whereof 11 neonates), with non-central venous line-related and nonmalignancy-related venous thromboembolism (VTE) at uncommon sites, referred to our Unit from January 1999 to January 2012. Thirty patients who also suffered deep vein thrombosis, but in upper/low extremities, were not included in the analysis. The location of rare site VTE was: portal (n=7), mesenteric (n=2) and left facial vein (n=1), spleen (n=3), lung (n=3), whereas 10 neonates developed renal venous thrombosis. The majority of patients (91.7%) had at least 1 risk factor for thrombosis. Identified thrombophilic factors were: antiphospholipid antibodies (n=2), FV Leiden heterozygosity (n=6), MTHFR C677T homozygosity (n=4), protein S deficiency (n=2), whereas all neonates had age-related low levels of protein C and protein S. All but 6 patients received low-molecular-weight heparin, followed by warfarin in 55% of cases, for 3 to 6 months. Prolonged anticoagulation was applied in selected cases. During a median follow-up period of 6 years, the clinical outcome was: full recovery in 15 patients, evolution to both chronic portal hypertension and esophageal varices in 2 children, and progression to renal failure in 7 of 10 neonates. Neonates are greatly vulnerable to complications after VTE at uncommon sites, particularly renal. Future multicentre long-term studies on neonatal and pediatric VTE at unusual sites are considered worthwhile.

Abstract
Non-cirrhotic portal hypertension (NCPH) encompasses a wide range of disorders, primarily vascular in origin, presenting with portal hypertension (PHT), but with preserved liver synthetic functions and near normal hepatic venous pressure gradient (HVPG). Non-cirrhotic portal fibrosis/Idiopathic PHT (NCPF/IPH) and extrahepatic portal venous obstruction (EHPVO) are two prototype disorders in the category. Etiopathogenesis in both of them centers on infections and prothrombotic states. Presentation and management strategies focus on repeated well tolerated episodes of variceal bleed and moderate to massive splenomegaly and other features of PHT. While the long-term prognosis is generally good in NCPF, portal biliopathy and parenchymal extinction after prolonged PHT makes outcome somewhat less favorable in EHPVO. While hepatic schistosomiasis, congenital hepatic fibrosis and nodular regenerative hyperplasia have their distinctive features, they often present with NCPH.

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
The natural history of portal cavernoma cholangiopathy (PCC) is poorly defined and poorly understood. It develops early after acute portal vein thrombosis (PVT) if there is failure of recanalization. In PCC, the likelihood of progression of biliary abnormalities after 1 year is extremely low. The natural history of PCC is conveniently divided into asymptomatic and symptomatic stages. The majority of patients with PCC are asymptomatic and are detected incidentally on imaging. Limited data suggest that asymptomatic PCC is static or only slowly progressive in the initial stages. However, most workers agree that, overall, PCC is a slowly progressive disease. Symptomatic PCC represents a late stage in its natural history. Finding strictures with dilatation at cholangiography is associated with a higher risk of developing symptoms of PCC. Onset of symptoms is often precipitated by the development of biliary sludge or calculi and treating calculi usually relieves symptoms for prolonged periods of time. Clinical presentations include biliary pain, obstructive jaundice, acute cholangitis, acute cholecystitis, or other presentations of gallstone disease. Progressive liver dysfunction and secondary biliary cirrhosis can develop in a minority of patients.

Abstract
Portal cavernoma cholangiopathy (PCC) is defined as abnormalities in the extrahepatic biliary system including the cystic duct and gallbladder with or without abnormalities in the 1st and 2nd generation biliary ducts in a patient with portal cavernoma. Presence of a portal cavernoma, typical cholangiographic changes on endoscopic or magnetic resonance cholangiography and the absence of other causes of these biliary changes like bile duct injury, primary sclerosing cholangitis, cholangiocarcinoma etc are mandatory to arrive a diagnosis. Compression by porto-portal collateral veins involving the paracholedochal and epicholedochal venous plexuses and cholecystic veins and ischemic insult due to deficient portal blood supply or prolonged compression by collaterals bring about biliary changes. While the former are reversible after porto-systemic shunt surgery, the latter are not. Majority of the patients with PCC are asymptomatic and approximately 21% are symptomatic. Symptoms in PCC could be in the form of long standing jaundice due to chronic cholestasis, or biliary pain with or without cholangitis due to biliary stones. Endoscopic retrograde cholangiography has no diagnostic role because it is invasive and is associated with risk of complications, hence it is reserved for therapeutic procedures. Magnetic resonance cholangiography and portovenography is a noninvasive and comprehensive imaging technique, and is the modality of choice for mapping of the biliary and vascular abnormalities in these patients. PCC is a progressive condition and symptoms develop late in the course of portal hypertension only in patients with severe or advanced changes of cholangiopathy. Asymptomatic patients with PCC do not require any treatment. Treatment of symptomatic PCC can be approached in a phased manner, coping first with biliary clearance by nasobiliary or biliary stent placement for acute cholangitis and endoscopic biliary sphincterotomy for biliary stone removal; second, with portal decompression by creating portosystemic shunt; and third, with persistent biliary obstruction by performing second-stage biliary drainage surgery such as hepaticojejunostomy or choledochoduodenostomy. Patients with symptomatic PCC have good prognosis after successful endoscopic biliary drainage and after successful shunt surgery.

Abstract
BACKGROUND The management of extrahepatic portal vein obstruction (EHPVO) in children is controversial. We report our experience with a prospective evaluation of a stepwise protocol based on severity of portal hypertension and feasibility of mesoportal bypass (MPB). METHODS After diagnosis, children with EHPVO underwent surveillance endoscopies and received nonselective β-blockers (NSBBs) or endoscopic variceal obliteration (EVO) when large varices were detected. In patients who failed NSBBs and EVO, we considered MPB as first-line and shunts or transjugular intrahepatic portosystemic shunt (TIPS) as second-line options. RESULTS Sixty-five children, median age 12.5 (range 1.6-25.8), whose age at diagnosis was 3.5 (0.2-17.5) years, were referred to our unit. Forty-three (66%) had a neonatal illness, 36 (55%) an umbilical vein catheterisation. Thirty-two (49%) presented with bleeding at a median age of 3.8 years (0.5-15.5); during an 8.4-year follow-up period (1-16), 43 (66%) had a bleeding episode, 52 (80%) were started on NSBBs, 55 (85%) required EVO, and 33 (51%) required surgery or TIPS. The Rex recessus was patent in 24 of 54 (44%), negatively affected by a history of umbilical catheterisation (P = 0.01). Thirty-four (53%) patients underwent a major procedure: MPB (13), proximal splenorenal (13), distal splenorenal (2), mesocaval shunt (3), TIPS (2), and OLT (1). At the last follow-up, 2 patients died, 53 of 57 (93%) are alive with bleeding control, 27 of 33 (82%) have a patent conduit. CONCLUSIONS Children with EHPVO have a high rate of bleeding episodes early in life. A stepwise approach comprising of medical, endoscopic, and surgical options provided excellent survival and bleeding control in this population.

Abstract
Portal vein thrombosis (PVT) is a common cause of portal hypertension in children. Predisposing conditions for PVT are obscure in more than half of the cases. Variceal bleeding and splenomegaly are the most frequent initial manifestations. Radiologic imaging studies are the mainstay for diagnosis. Treatment includes pharmacologic, endoscopic, and surgical modalities. β-Adrenergic blockers are not routinely used in children because of unproven efficacy and significant adverse effects. Endoscopic methods, such as sclerotherapy and endoscopic variceal ligation (EVL), are highly effective in the treatment of acute variceal bleeding and eradication of varices. EVL is the treatment of choice because of minimal complications and the need for few endoscopic sessions. EVL facilitates portal decompression either by the formation of collateral vessels or by surgical portosystemic shunting, when vessels grow to the proper diameter for anastomosis. Surgical portosystemic shunts are reserved for refractory cases because of significant complications and technical difficulties. Transjugular portosystemic shunts have an emerging role in the management of portal hypertension caused by PVT. PVT may occur in the posttransplant setting, but optimal management is not defined yet.

Abstract
BACKGROUND Major complications of noncirrhotic portal hypertension (NCPH) include bleeding esophagogastric varices, hypersplenism, ascites, and bowel ischemia under acute circumstances. The aim of this article is to determine the outcomes of surgical and endovascular treatments for severe complications from NCPH. METHODS From January 2000 to June 2011, 56 patients with symptomatic NCPH underwent open surgery or endovascular thrombolysis. The medical records were retrospectively reviewed. Of the 56 patients, there were 39 males and 17 females. The mean age was 21 years, ranging from 2 to 54 years. Forty-one of them were diagnosed to have prehepatic portal vein obstruction (PHPVO), 9 had Budd-Chiari syndrome (BCS), and 6 had noncirrhotic portal fibrosis (NCPF). All patients were symptomatic from 5 days to 14 years (mean 25 months). Portosystemic shunt (PSS) was primarily performed in 49 patients. Shunts were as follows: 35 mesocaval; 7 splenorenal; 4 portocaval; 2 paraumbilical-jugular; and 1 portal to right atrial. Esophagogastric devascularization was performed in 3 patients, but was converted to mesocaval shunt later in 2. The remaining 4 patients with acute superior mesenteric vein (SMV) and portal vein thrombosis were treated with endovascular catheter-directed thrombolysis. Warfarin was prescribed to all the patients for at least 6 months. Mean follow-up was 57 months, ranging from 2 to 125 months. The outcomes, focusing on 30-day mortality, recurrent bleeding, and hypersplenism, were recorded. RESULTS In the 49 patients undergoing primary PSS, the shunts remained patent and there was no recurrent variceal bleeding during the follow-up. All 3 patients with esophagogastric devascularization had recurrent variceal bleeding at 8, 13, and 24 months postoperatively. Two of them were converted to mesocaval shunt, and 1 died before redo operation. Thrombolysis in all 4 patients with acute SMV and portal thrombosis was technically successful. Three of the 4 survived without complications and 1 died from small bowel infarction due to recurrent thrombosis 40 days later. In the 47 patients with hypersplenism, mean platelet counts increased from 43×10(9)/L to 239×10(9)/L 2 weeks after surgery. Ascites in 30 of the 31 patients disappeared within 2 months after PSS. There was no postoperative encephalopathy, and perioperative 30-day mortality was 0%. CONCLUSIONS PSS can be employed to treat bleeding esophagogastric varices and severe hypersplenism secondary to NCPH. Post-PSS encephalopathy is less of a concern in NCPH patients with normal liver function. Endovascular catheter-directed thrombolysis via superior mesenteric artery is a useful alternative treatment for acute portal and/or mesenteric venous thrombosis.

Abstract
BACKGROUND AND AIM The prevalence of inherited antithrombin (AT), protein C (PC), and protein S (PS) deficiencies in portal vein system thrombosis (PVST) and Budd-Chiari syndrome (BCS) are substantially varied in different studies. No quantitative syntheses of these studies have been performed. A systematic review and meta-analysis were conducted to examine the prevalence of inherited AT, PC, and PS deficiencies in these patients and to compare the prevalence with healthy subjects. METHODS PubMed, EMBASE, and Cochrane Library databases were employed to identify all studies in which inherited AT, PC, and PS deficiencies in PVST and/or BCS were evaluated by family study or gene analysis. Prevalence and odds ratios of these inherited deficiencies were pooled; heterogeneity among studies was evaluated. RESULTS Nine studies were included in our meta-analysis. The pooled prevalence of inherited AT, PC, and PS deficiencies were 3.9%, 5.6%, and 2.6% in PVST, and 2.3%, 3.8%, and 3.0% in BCS, respectively. Heterogeneity among studies was not significant except for the analysis of inherited PC deficiency in BCS. Three studies compared the prevalence of these inherited deficiencies between PVST patients and healthy subjects. The pooled odds ratios of inherited AT, PC, and PS deficiencies for PVST patients were 8.89 (95% confidence interval [CI] 2.34-33.72, P = 0.0011), 17.63 (95% CI 1.97-158.21, P = 0.0032), and 8.00 (95% CI 1.61-39.86, P = 0.011), respectively. Only one study demonstrated that no inherited deficiency was found in both BCS patients and healthy subjects. CONCLUSIONS Inherited AT, PC, and PS deficiencies are rare in PVST and BCS. These inherited deficiencies increase the risk of PVST.

Management of bleeding in extrahepatic portal venous obstruction. Int J Hepatol 2013; 2013:784842.

Abstract
Extrahepatic portal venous obstruction, although rare in the western world, is a common cause of major and life threatening upper gastrointestinal bleeding among the poor in developing countries. Patients have large spleens and stunted growth. The diagnosis is easily confirmed by Doppler ultrasonography. Endoscopy sclerotherapy is the best option for the control of acute variceal bleeding. For secondary prophylaxis of bleeding, the choice lies between repeated sclerotherapy and a portosystemic shunt. We believe that due consideration should be given to performing a splenectomy and a lienorenal shunt. Performed by experienced surgeons, it carries a low operative mortality of 1%, a rebleeding rate of about 10%, removes the large spleen, reverses hypersplenism, and is not followed by portosystemic encephalopathy. Most importantly, it is a onetime procedure particularly suited to those who have little access to blood transfusion and sophisticated medical facilities.

Abstract
OBJECTIVE The aim of this study was to describe the prevalence of main hereditary thrombophilias, Janus kinase 2 (JAK2) V617F mutation, antiphospholipid antibody syndrome (APS), and hyperhomocysteinemia in Brazilian children and adolescents diagnosed with portal vein thrombosis (PVT) without associated hepatic disease. METHODS A cross-sectional study was carried out with 32 children with PVT in accompaniment at Hospital das Clínicas of the Universidade Federal de Minas Gerais from January 1990 to July 2011. Laboratory evaluation of thrombophilias was performed from September 2010 to July 2011. RESULTS Thirty-two patients were evaluated; 59% were boys. Median age at diagnosis was 2.4 years. Mean time of patients' accompaniment was between 4.7 and 5.2 years. The presence of hereditary and acquired thrombophilias occurred in 34.4% of patients, and 9 of them also showed other risk factors in the previous history evaluation. Risk factors were absent in the previous history of 18 patients (56.3%). Two patients showed persistent high titres of anticardiolipin antibodies. Hyperhomocysteinemia was not observed. One patient was heterozygous for factor V Leiden and prothrombin G20210A mutation (3.1%). Eleven patients (34.4%) showed heterozygous methylenetetrahydrofolate reductase (MTHFR) C677T, and no patient had the JAK2V617F mutation. CONCLUSIONS Even after investigation of main hereditary and acquired thrombophilia, PVT remains without apparent cause in most patients. Nevertheless, association of local and systemic risk factors seems to be important also in the pediatric age group. Therefore, despite the low prevalence, a complete investigation, which includes both hereditary and acquired thrombophilias, may be necessary.

Abstract
CONTEXT Portal vein thrombosis refers to a total or partial obstruction of the blood flow in this vein due to a thrombus formation. It is an important cause of portal hypertension in the pediatric age group with high morbidity rates due to its main complication - the upper gastrointestinal bleeding. OBJECTIVE To describe a group of patients with portal vein thrombosis without associated hepatic disease of the Pediatric Hepatology Clinic of the Hospital das Clínicas, Universidade Federal de Minas Gerais, Belo Horizonte, MG, Brazil with emphasis on diagnosis, presentation form and clinical complications, and the treatment of portal hypertension. METHODS This is a descriptive study of a series of children and adolescents cases assisted from January 1990 to December 2010. The portal vein thrombosis diagnosis was established by ultrasound. RESULTS Of the 55 studied patients, 30 (54.5%) were male. In 29 patients (52.7%), none of the risk factors for portal vein thrombosis was observed. The predominant form of presentation was the upper gastrointestinal bleeding (52.7%). In 20 patients (36.4%), the initial manifestation was splenomegaly. During the whole following period of the study, 39 patients (70.9%) showed at least one episode of upper gastrointestinal bleeding. The mean age of patients in the first episode was 4.6 ± 3.4 years old. The endoscopic procedure carried out in the urgency or electively for search of esophageal varices showed its presence in 84.9% of the evaluated patients. The prophylactic endoscopic treatment was performed with endoscopic band ligation of varices in 31.3% of patients. Only one died due to refractory bleeding. CONCLUSIONS The portal vein thrombosis is one of the most important causes of upper gastrointestinal bleeding in children. In all non febrile children with splenomegaly and/or hematemesis and without hepatomegaly and with normal hepatic function tests, it should be suspect of portal vein thrombosis. Thus, an appropriate diagnostic and treatment approach is desirable in an attempt to reduce morbidity and mortality.

Abstract
OBJECTIVE The objective of this article is to illustrate the imaging features of patients with extrahepatic portal venous obstruction who are evaluated before or after a Rex shunt surgery. CONCLUSION The Rex shunt is a potentially curative surgical procedure that reestablishes physiologic hepatopetal portal flow. It is typically accomplished by interposing a vascular conduit between the superior mesenteric vein to the still patent intrahepatic portal venous system. This procedure results in resolution of portal hypertension.

Abstract
OBJECTIVES Cavernous transformation of the portal vein (CTPV) is considered a sequel to extrahepatic portal vein obstruction. However, we have observed an unusual finding of cavernous vessels around a patent portal trunk in the liver hilum. The aim of our study is to describe the imaging features, clinical profiles, management, and outcome of these patients. MATERIAL AND METHODS We re-evaluated the images of all consecutive non-malignant and non-cirrhotic patients with a diagnosis of CTPV admitted to our department between July 2002 and June 2010. The patients with a patent portal trunk were enrolled in this study. RESULTS A total of five patients had cavernous vessels around a patent portal trunk. Of them, all presented with abdominal distension, and one with recurrent variceal bleeding. Hepatomegaly and splenomegaly were found in one and four patients, respectively. All but one with previous splenectomy had a decreased platelet count. Three patients had a high level of alkaline phosphatase and/or γ-glutamyl transferase. Serum bilirubin, albumin, and creatinine were in normal range. Endoscopy demonstrated varices in three patients. Mild ascites was detected in one patient by ultrasound. Conservative therapy was given to two patients with mild abdominal discomfort. Splenectomy or partial spleen embolization was given to two patients with hypersplenism. A transjugular intrahepatic portosystemic shunt insertion was performed in one patient for the prevention of recurrent variceal bleeding. All patients were alive during follow-up. CONCLUSIONS These unusual findings led us to believe that cavernous vessels could develop around a patent portal trunk. Further studies are necessary to explore its pathogenesis.

Abstract
PURPOSE To evaluate liver stiffness (LS) and spleen stiffness (SS) in patients with extrahepatic portal vein obstruction (EHPVO). MATERIALS AND METHODS Institutional research board approval and informed consent were obtained. LS and SS were measured in 65 consecutive patients with EHPVO. Patients underwent endoscopy, liver biopsy, liver function tests, abdominal ultrasonography, a detailed history, and examination. LS and SS measurements were also obtained in 50 age-matched healthy control subjects. Comparisons were made by using the Student t test, Mann-Whitney test for quantitative data, and χ(2) or Fisher exact test for qualitative data. RESULTS Sixty-five patients with EHPVO (with a bleed, n = 45; without a bleed, n = 20; mean age, 25.4 years ± 10.7 [standard deviation]; 29 men, 36 women) were enrolled. Twenty-two (34%) had hypersplenism. LS (P = .001) and SS (P = .01) were higher in patients with EHPVO (6.7 kPa ± 2.3 and 51.7 kPa ± 21.5, respectively) than in control subjects (4.6 kPa ± 0.7 and 16.0 kPa ± 3.0, respectively). Patients who had a bleed had higher SS than did those without a bleed (60.4 kPa ± 5.4 vs 30.3 kPa ± 14.2, P = .01). There was no significant difference in age (26.7 years ± 10.4 vs 22.5 years ± 9.8, P = .8) and median duration of disease (4.5 years [range, 1-26 years] vs 6.0 years [range, 1-22 years], P = .23) in patients with a bleed versus those without. With a cutoff of 5.9 kPa for LS, sensitivity and specificity for detection of a variceal bleed were 67% and 75%, respectively. An SS cutoff of 42.8 kPa yielded sensitivity and specificity of 88% and 94%, respectively. CONCLUSION LS and SS were higher in patients with EHPVO than in control subjects, and patients with a history of a bleed had a higher SS than did those without a bleed.

Abstract
Portal biliary ductopathy (PBD) is a condition in which biliary and pancreatic ducts are extrinsically compressed by collateral branches of the portal venous system, which in turn have become dilated and varicosed due to portal hypertension. While the majority of patients with PBD are asymptomatic, a minority can present with symptoms of biliary obstruction and cholangitis with the potential of developing secondary chronic liver disease. This paper reports the case of a 29 year old male presenting with acute cholangitis, in whom PBD was diagnosed radiologically. A brief review of current literature regarding the diagnosis and management of this condition will also be presented.

Abstract
BACKGROUND/OBJECTIVES The optimal management of children with noncirrhotic portal hypertension is controversial. Some groups suggest early and aggressive surgical intervention, while others report long-term success with conservative management. METHODS We conducted a retrospective study of 26 patients with noncirrhotic portal hypertension treated at our institution. We compared platelet counts, white blood cell (WBC) counts, spleen size, hospital admissions, gastrointestinal bleeds, and longitudinal trends of specific clinical parameters using standard univariate and time-trend analytic techniques. RESULTS Mean age at the time of diagnosis was 5.2 years. Portal vein thrombosis was found in 84.6% of patients (n=22). There was one mortality related to malignancy. There was not a progression of hypersplenism in patients that did not receive a shunt and conversely, we did not notice a significant decrease in spleen size following shunt surgery (P=0.2). Platelet and WBC counts trended downward among patients managed medically, while platelets increased and WBC counts remained stable in surgical patients. There was a significant decrease in hospital admissions for gastrointestinal bleeding following surgical intervention in the shunt group compared with nonshunt (P=0.0009). CONCLUSION While our analysis was limited given small sample sizes and selection bias, it suggests that the majority of pediatric patients with noncirrhotic portal hypertension will do well long-term without surgical intervention.

Abstract
This review summarizes the document elaborated by the Italian Association for the Study of the Liver (AISF) ad hoc committee "Vascular disorders of the liver" on the primary circulatory liver diseases, which include Budd-Chiari syndrome, obstruction of the hepatic portion of the inferior vena cava, portal vein thrombosis, sinusoidal obstruction syndrome (veno-occlusive disease) and hereditary hemorrhagic telangiectasia. A characteristic of the primary circulatory liver diseases is that portal hypertension usually precedes liver dysfunction. Significant overlap exists amongst the diseases and risk factors that predispose patients to the primary circulatory liver diseases, though the pathogenesis of individual diseases varies. Management of the different vascular disorders is very peculiar and often multidisciplinary and patients should be referred to a tertiary referral centre for optimal care.

Abstract
BACKGROUND Extrahepatic portal vein thrombosis (EHPVT) is an important cause of portal hypertension in children. Rex shunt has been used successfully to treat these patients. METHODS We report our experience in 19 infants and children (5 months to 14 years) with HPVT eligible for a mesenteric-portal surgical shunt with left internal jugular vein autograft. Eight children had idiopathic EHPVT, nine had post-umbilical catheterization EHPVT, one had portal vein agenesis, and one had posttransplant EHPVT. RESULTS It was possible to perform the Rex shunt in all patients except for 8 of 9 cases in the post-umbilical catheterization EHPVT group. A Warren procedure was performed in 4 of those patients and a proximal splenorenal shunt in 1. Current follow-up ranges from 3 to 26 months. Shunt thrombosis occurred in one patient with portal vein agenesis and associated cardiac anomaly. Portal hypertension has significantly improved after surgery. None of our patients have experienced new bleeding episodes until now. CONCLUSIONS The Rex shunt should be considered in the treatment of children with idiopathic EHPVT experiencing repeated gastrointestinal bleeding episodes refractory to endoscopic treatment. Nevertheless, the role of this operation for children with post-umbilical catheterization EHPVT is yet to be clearly evaluated.
