ABSTRACT Objective: This study aims to evaluate dietary intake, nutritional status, and growth rate in children and adolescents with extrahepatic portal vein obstruction and portal hypertension. Methods: Outpatients aged 1-18 years, diagnosed with extrahepatic portal vein obstruction and portal hypertension, who had no associated diseases, and who had not been subjected to a venous shunt were included in this study. Two evaluations were carried out in this study: an initial (evaluation 1) and a final evaluation (evaluation 2), with a three-month minimum interval between them. In each evaluation, dietary intake was analyzed comparing the results with recommended energy intake using the Harris & Benedict equation and participants’ anthropometric data, such as weight, height, mid-arm muscle circumference, weight-for-age, height-for-age, and body mass index-for-age, based on the World Health Organization 2006 standards. Results: A total of 22 patients participated in this study. There was a significant improvement in weight, height, body mass index, and mid-arm muscle circumference measurements (p<0.001; p<0.001; p<0.017; p=0.0018 respectively) and in the relationship between dietary intake and energy recommended energy intake, according to the Harris & Benedict equation (p=0.0001) from the first and second evaluation. Conclusion: Extrahepatic portal vein obstruction and portal hypertension were not shown to be factors predisposing to malnourishment.

Rex Shunt

Portal hypertension is a result of an increase in intrahepatic resistance in the main portal vein. The Meso-Rex shunt is used to bypass the obstructed portal vein and restore the venous flow into the liver. This procedure alleviates the need for a hepatic transplant. The Meso-Rex shunt has proven to be an effective treatment for extrahepatic portal vein obstruction, thus saving children from a complete transplant. There are variants to this bypass surgery, and sonography is commonly used to assess the condition pre- and postoperatively. In this case, the shunt was uniquely different from the typical Meso-Rex bypass surgery. Particular vasculature made it imperative for the sonographer to review the prior sonograms and review the chart information before preforming the examination. It should also be noted that sonographers must adapt the protocols to give the utmost treatment.

Portal Vein Obstruction

Extrahepatic portal vein obstruction, although rare in children, is a significant cause of portal hypertension (PHT) leading to life-threatening gastrointestinal bleeding in the pediatric age group. PHT may also lead to other complications such as hyperesplenism, cholangyopathy, ascites, and even hepatopulmonary syndrome and portopulmonary hypertension that may require organ transplantation. Herein we report the case of an asymptomatic 11-month-old infant wherein a hepatomegaly and cavernous transformation of the portal vein was detected by liver ultrasound. Neither signs of thrombosis in arteriovenous system, nor affectation of biliary tract were identified in the magnetic resonance imaging study. A significant enlargement of the caudate lobe of the liver was reported. No risk factors were detected. The differential diagnosis performed was extensive. Inherited thrombophilia and storage disorders were especially considered. Liver biopsy was normal. Upper gastrointestinal esophagogastroduodenoscopy detected two small varicose cords on the distal third of the esophagus. Finding a cavernous transformation of the portal vein with evidence of collateral circulation in such an early age is a challenging condition for professionals, since PHT may lead to severe complications during childhood and can compromise growth and development. Evidence-based guidelines for the management of PHT in adults have been published. However, follow-up and treatment of pediatric patients have not yet been standardized. Moreover, management of PHT in infants faces particular difficulties such as technical restrictions that could hinder their treatment.

Normal Ultrasound

Idiopathic portal hypertension is a benign long-standing non-cirrhotic portal hypertension with no typical laboratory findings and absence of stigmata of chronic liver disease. The disease is diagnosed by the presence of evidence of portal hypertension with preserved liver function and absence of extrahepatic portal vein obstruction. We report the case of a 71-year-old woman who was admitted in hospital with encephalopathy and hyperammonemia. Liver biochemical tests excluded cirrhosis but revealed pancytopenia; preliminary abdomen ultrasound was normal. Ultrasound doppler and abdomen computed tomography of portal vein revealed patent portal vein with impaired portal intrahepatic perfusion and portal-systemic shunts.

Detailed Clinical History

Background: The incidence of esophageal varices in patients with cirrhosis ranges from 35 to 80%. Thus, screening all cirrhotic patients with upper gastrointestinal (UGI) endoscopy to detect the presence of varices implies a number of unnecessary endoscopies, which increase the workload of endoscopy units and UGI endoscopy has its own limitations. The present study was conducted to investigate series of non-invasive biochemical and radiological markers for prediction of esophageal varices in patients with portal hypertension.Methods: Patients of either sex, aged 18-80 years with diagnosis of chronic liver disease, cirrhosis, extrahepatic portal vein obstruction or any other cause of portal hypertension were studied. Patients were subjected to UGI endoscopy within 2 weeks of investigation of laboratory parameters. All patients were subjected to detailed clinical history and physical examination and biochemical and radiological investigations. Endoscopy was done with an olympus gastroscope using 20% xylocaine spray.Results: Out of 51 patients in the study, esophageal varices were seen in 34 (66.67%) patients and absent in 17 (33.33%) patients. On multiple logistic regression analysis, the variables independently linked to the presence of esophageal varices were; spleen diameter [odds ratio (OR): 1.137, 95% confidence interval: 1.033-1.255; p=0.009] and Portal vein size [odds ratio (OR): 41.531, 95% confidence interval: 1.858-928.304; p=0.019].Conclusions: Non-invasive prediction for varices by biochemical and radiological methods are reliable methods for screening of cirrhotics patients because of increasing patient overload, when a major chunk of these patients do not show any evidence of varice.
