ABSTRACT
Objective To investigate the disease categories of the upper alimentary tract and the ratio of Hp infection in countryside children. Methods 96 children with complaint in upper digestive tracts underwent gastro-scope and in each patient,a piece of mueosal tissue in sinus ventrieuli was taken out to perform Hp urase test. Results All of the 96 children were detected abnormal including chronic superficial gastritis (n = 63), ulcer of duodenal bulb(n = 13) ,enteritis of duodenal bulb(n =7) ,gastritis with bile reflux(n =4) ,erosive gastritis(n =2) ,ascariasis (n = 6), aneylestomiasis(n = 3). The positive rate was 100%. 49/96 (51%) were positive in Hp test, including 36/ 63(57.1%) of chronic gastritis ,10/13(76.9%) of ulcer of duodenal bulb,2/7 (28.6%) of enteritis of duodenum. Hp were positive in 11 (35.5%) in the group with age range from 3 to 6 years old and positive in 38 (58.5%) in the group with age range from 7 to 12 years old. Conclusion Chronic superficial gastritis and ulcer of duodenal bulb were the main findings in gastrescopy in children with a upper digestive tract complaint. Hp infection ratio was highest in patients with ulcer of duodenal bulb in our study, and followed by the chronic gastritis. And the infection rate in-creased with the age increased.
