Undetected hepatomegaly in obese children by primary care physicians: a pitfall in the diagnosis of pediatric nonalcoholic fatty liver disease.

The diagnostic evaluation of nonalcoholic fatty liver disease (NAFLD) relies on the initial detection of hepatomegaly or elevated serum aminotransferases by the primary care provider. In this investigation, the aptitude of the primary care provider to identify children with hepatomegaly and initiate an evaluation for NAFLD is determined. The physical examination findings and requests for diagnostic testing of 18 primary care physicians (and pediatric gastroenterologists) on 11 obese school-aged children, including a subset of children with hepatomegaly and NAFLD, were analyzed.
