EHPVO SARIN PDF

Muzilkree Frequency of gastropathy and gastric varices in children with extrahepatic portal venous obstruction treated with sclerotherapy. Besides variceal bleeding, which is the commonest presentation, patients sarij have symptomatic portal biliopathy, hypersplenism, and growth retardation. The natural history of portal hypertensive gastropathy: Despite the clear cut benefit ehpov EVL when used alone, there is a higher risk of recurrence of varices as it is difficult to ligate smaller varices, and because perforators and paraesophageal collaterals remain patent after EVL. The present review is intended to provide the existing literature on etiopathogenesis, clinical profile, diagnosis, natural history and management of IPH and EHPVO.

Kelmaran Despite the clear cut benefit of EVL when used alone, there is a higher risk of recurrence of varices as it is difficult to ligate smaller varices, and because perforators and paraesophageal collaterals remain patent after EVL. Portal hypertensive gastropathy in children. The present review is intended to provide the existing literature on etiopathogenesis, clinical profile, diagnosis, natural history and management of IPH and EHPVO.

Diagnosis is often clinical, supported by simple radiological tools. Further research is needed to understand the pathogenesis and natural history of these disorders. Management of portal biliopathy. Extrahepatic portal vein obstruction. The postulated mechanisms of biliary changes in EHPVO are extrinsic compression by portal collaterals,[ 44] ischemic stricture of bile duct due to injury ehpov the time of portal venous thrombosis[ 45 ] or ehpvk combination of both.

Diagnostic upper GI endoscopy for hematemesis in children: This suggests that children with EHPVO have growth failure and decreased growth velocity despite adequate nutrition. However, since most of the patients are asymptomatic, this approach is recommended only if a therapeutic intervention is contemplated. Nevertheless, EST cannot be totally ruled out as a therapeutic modality, especially in children. Portal hypertensive gastropathy in non-cirrhotic patients. H-type shunt with an autologous venous graft for treatment of portal hypertension in children.

Growth failure, portal biliopathy and minimal hepatic encephalopathy are additional concerns in EHPVO. After hemodynamic resuscitation all such patients should undergo endotherapy [either sclerotherapy EST or band ligation EVL ]. Itha S, Yachha SK. However, controversy exists regarding prevention of further bleed.

Portal biliopathy is the term used to describe cholangiographic abnormalities of the extrahepatic and intrahepatic bile ducts in patients with EHPVO. Bleeding from rectal varices can be managed with sclerotherapy or band ligation. Relation of insulin-like growth factor-1 and insulin-like growth factor binding protein-3 levels to growth retardation in extrahepatic portal vein obstruction. The debate is whether to send a child for shunt surgery preferably Rex shunt immediately after controlling acute variceal bleeding with endotherapy or to continue endotherapy to prevent further bleed and to offer shunt ehpo as and when the child needs it.

Egpvo hypertension, children, biliopathy, growth, sclerotherapy. The definitive method of diagnosis of portal biliopathy is ERCP. In this article we will discuss the management of EHPVO under the headings of etiology, management of variceal bleeding, ectopic varices, portal biliopathy, growth failure and the role of shunt surgery. Significantly increased levels of growth hormone and decreased levels of insulin-like growth factor-1 IGF-1 and insulin-like growth factor binding protein-3 IGFBP-3 have been noted in EHPVO patients, suggesting growth hormone resistance.

There is no controversy about the management of acute variceal bleeding. Endoscopic ligation plus sclerotherapy: Fifteen-year follow up of endoscopic injection sclerotherapy in children with extrahepatic portal venous obstruction.

The prevalence and spectrum of colonic lesions in patients with cirrhosis and noncirrhotic portal hypertension. Symptomatic biliary obstruction can be managed endoscopically but shunt surgery followed by biliary sxrin if necessary seems to be the best management option.

Indeed, EVL has become the preferred mode of treatment of variceal bleeding in adults. Although the liver may appear normal, functional compromise develops in the long term. A longer interval up to 1 year and documentation of a patent shunt with decompressed collaterals on color Doppler or MR angiography may help in determining the optimum time for surgery.

It is expected that the incidence of rectal varices with and without rectal bleeding will rise in children as they approach adolescence and adulthood.

Idiopathic portal hypertension and extrahepatic portal venous obstruction. Is it superior to sclerotherapy in children with extrahepatic portal venous obstruction? J Pediatr Gastroenterol Nutr. Primary biliary tract surgery has significant morbidity and mortality due to extensive collaterals around the bile ducts. Variceal bleeding in EHPVO can be successfully managed by endoscopic obliteration of varices, which has low morbidity but requires repeated visits, or by portosystemic shunt surgery, which provides good control of bleeding, possibly helps growth retardation, hypersplenism, and protects against future development of portal biliopathy but is associated with surgical mortality and is sometimes not feasible due to nonavailability of a satisfactory vessel.

Portal hypertensive gastropathy in children with extrahepatic portal venous obstruction: Abstract Extrahepatic portal venous obstruction EHPVO is the commonest cause of portal hypertension and variceal bleeding in children. The portal vein is transformed into a cavernoma, resulting in portal hypertension and oesophagogastic varices. Growth retardation constitutes a relative indication for mesenterico-portal bypass Rex shunt surgery. Consensus on extra-hepatic portal vein obstruction.

In patients with endoscopic failure, a staged procedure portosystemic shunt followed by biliary surgery should be preferred. Natural history is defined by episodes of variceal bleed and symptoms related to enlarged spleen. Management of esophageal varices.

Of the two modalities of endotherapy, EST is an established modality to tackle varices in children Table 1. EHPVO is the commonest cause of portal hypertension and variceal bleeding in children. Longterm studies after endotherapy have shown almost no mortality. Studies in children have shown that hereditary or acquired coagulation disorders do not play a role in the pathogenesis of EHPVO in children. Infections, autoimmunity, drugs, immunodeficiency and prothrombotic states are possible etiological agents in IPH. Though the role of anticoagulation therapy remains controversial in adults,12 there is no role of anticoagulation therapy in children with EHPVO.

Aranos Besides variceal bleeding, which is the commonest presentation, patients may have symptomatic portal biliopathy, hypersplenism, and growth retardation. Introduction Extrahepatic portal venous obstruction EHPVO is the commonest cause of portal hypertension in children [12] and one of the common causes in adults in India. Correction of extrahepatic portal vein thrombosis by the meserteric to left portal vein bypass. Magnetic resonance MR imaging with intravenous gadolinium injection delineate the cavernoma and biliary changes simultaneously and may be extremely useful in children.
