title: Clinical and laboratory differentiation of cirrhosis and extrahepatic portal venous obstruction in children.
abstract: OBJECTIVE
  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.
  
  
  CONCLUSIONS
  Presence of UGI bleeding and the absence of jaundice are 97.5% accurate in predicting diagnosis of EHPVO.
