目的　探明小儿上消化道出血的病因。方法　对 10 0例上消化道出血患儿进行纤维胃镜检查。结果发现病变者 93例 (93% )。以十二指肠球部溃疡最多见 ,有 33例 (33% ) ;其次为重度浅表性胃炎 19例 (19% ) ;其它依次为十二指肠球炎伴胃炎 11例 (11% ) ;食管炎 9例 (9% )和胃溃疡 8例 (8% ) ;检测幽门螺杆菌 (HP)阳性 6 0例 (6 0 % )。结论　小儿上消化道出血好发于学龄期儿童 ,以十二指肠球部溃疡所致出血最多见 ,且与HP感染密切相关。

Objective To study the etiology of upper gastrointestinal tract hemorrhage in children. Methods One hundred children with upper gastrointestinal tract hemorrhage were examined by gastroscopy. Results Abnormal findings were noted in 93% of patients, with duodenal bulbar ulcer being the commonest disorder (33%). Other abnormalities included severe superficial gastritis (19%), duodenitis accompanied by gastritis (11%), esophagitis (9%) and gastric ulcer (8%). HP test was positive in 60% of patients. Conclusions Upper gastrointestinal tract hemorrhage occurs frequently in school-age children. Duodenal bulbar ulcer is commonly observed and has a close correlation with HP infection.
