title: Portal gastropathy and duodenopathy in children with extrahepatic and intrahepatic portal hypertension: endoscopic diagnosis and histologic scoring.
abstract: OBJECTIVE
  The aim of the study was to determine the frequency of portal gastropathy (PG) and duodenopathy (PD) in children, to document the correlation of various clinical and laboratory parameters associated with portal hypertensive gastroduodenal lesions, to compare the endoscopic portal hypertensive lesions with different histologic findings, and to evaluate the use of a possible histologic scoring system.
  
  
  METHODS
  All children undergoing endoscopic investigation for portal hypertension (PH) between January 2006 and November 2007 were analysed retrospectively. Clinical and demographical data and endoscopic and histologic findings were recorded. Histologic findings suggestive of PG and PD (capillary dilation, increased numbers of capillaries, histologic bleeding, and edema) were scored.
  
  
  RESULTS
  Of 51 consecutive children (29 boys, mean age 10.1 ± 3.6 years [range 2.5-15.8 years]), 28 were cirrhotic. PG was diagnosed in 58.8% endoscopically. Children with cirrhotic PH had the highest rate of PG (64.3%), whereas those with extrahepatic or intrahepatic noncirrhotic PH were alike (50% and 54.5%, respectively). Baveno PG scores were higher in children with cirrhosis with higher Child-Pugh scores. Capillary dilation was the only histologic finding showing significant association with the endoscopic diagnosis. Only 9% had PD on endoscopy. None of the histologic findings correlated with endoscopic diagnosis of PD.
  
  
  CONCLUSIONS
  PG and PD are seen in children with extrahepatic and intrahepatic PH at rates similar to those reported in adult studies. Baveno PG scores increased in parallel with Child-Pugh class in children with cirrhosis. Capillary dilation was the only histologic finding showing significant association with the endoscopic diagnosis of PG in this study.
