Brief Summary:
Pediatric patients with chronic liver disease may have Minimal Hepatic Encephalopathy(MHE)which can cause changes in behavior,intelligence and neurological function.By utilizing cognitive and developmental testing we will determine if patients have MHE. If so, we will trial 3 months of blinded placebo or Lactulose treatment followed by a washout period with no treatment. At this time patients are re-tested and then begin another three month period switching to the opposite treatment of first 3 months.Final cognitive/developmental testing will determine if Lactulose treatment has any effect on MHE.

Condition or disease Intervention/treatment Phase
Minimal Hepatic Encephalopathy Drug: Lactulose Drug: placebo Phase 2

Detailed Description:
In addition ,serum ammonia levels will be obtained at beginning of study,post-washout and at end of study to evaluate Lactulose effect on serum ammonia.

Primary Outcome Measures :
  1. Incidence of Minimal Hepatic Encephalopathy (MHE) in Children With Cirrhosis [ Time Frame: baseline ]
    failure of one cognitive function test indicates presence of MHE


Secondary Outcome Measures :
  1. Health Related Quality of Life (HRQOL) [ Time Frame: baseline ]
    HRQOL administered to parents prior to treatment

  2. Effeccts of Lactulose Treatment on MHE as Measaured by Cognitive Function [ Time Frame: before and after each treatment period ]
    MHE as measured by failure of one or more cognitive test
