Objectives: The prevalence of duodenal ulcer (DU) in adult patients with portal hypertension is higher than in patients without portal hypertension . This study investigates the prevalence and characteristics of DU in children with portal hypertension. Patients and Methods: From January 1997 to December 200 1, 80 children with portal hypertension who had undergone upper intestinal endoscopic examinations were enrolled. Possible factors contributing to the development of DU including severity of liver disease, portal hypertension, H. pylori, and serum gastrin level were studied. The control group consisted of 80 age- and sex- matched children with gastrointestinal symptoms but no liver disease and who underwent endoscopic examination during the same period. Results: The prevalence of DU was significantly higher in children with portal hypertension than in children with digestive symptoms only (22.5% v 8.8%; P = 0.017). DU was more common and appeared earlier in children with a history of variceal bleeding. The presence of DU was independent of the severity of liver disease, H. pylori infection and serum gastrin level. Conclusion: DU occurs commonly in children with portal hypertension, especially in those who have had variceal bleeding. It is mandatory to screen a patient with gastrointestinal bleeding for DU even in the presence of esophageal varices. Elevated portal pressure might be a factor contributing to the development of DU.
