Clinical significance of C13 breath test detection and endoscopy in children with chronic abdominal pain.

Objective To understand the infection of Helicobacter pylori(H.pylori) in children with chronic abdominal pain and its endoscopic features.Method C13 urea breath test was applied to 905 cases of children with chronic abdominal pain as the main symptom.Electronic endonscopy was used to children whose C13 breath test result was positive.Result Among the 905 cases,185 cases were H.pylori-positive(20.44%),with the positive rate increasing along with age and reaching peak value at school age.The endoscopy showed there were 47(25.40%) cases of duodenal elevated lesions,41(22.1%) cases of nodular gastritis,38(20.5%) cases of chronic superficial gastritis,23(12.43%) cases of nodular gastritis with duodenal elevated lesions,23(12.4%) cases of duodenal ulcer.7(3.7%) cases of gastric ulcer(including 1 case of complex ulcer),and 6(3.2%) cases of nodular gastritis with duodenitis.Conclusion H.pylori infection is one of the main causes of chronic abdominal pain in children,which also leads to chronic gastritis and peptic ulcer.C13 breath test is an easy,fast,painless and non-radioactive way to detect H.pylori.Endoscopy can assist in clinical diagnosis and treatment of patients with both gastrointestinal symptoms and positive C13 breath test result.
