对１２３例非精神心里因素所致的再发性腹痛（ＲＡＰ）患儿进行胃镜检查及幽门螺杆菌（ＨＰ）检测。胃镜所见：正常１７例（１３８％），慢性胃炎（ＣＧ）６６例（５３７％），ＣＧ合并十二指肠球炎１３例（１０６％）、合并食管炎４例（３２％），消化性溃疡（ＰＵ）２２例（１７９％），幽门管狭窄１例（０８％）。采用三种方法检测ＨＰ：ＥＬＩＳＡ方法、ＰＣＲ技术及组织学染色找菌，ＨＰ阳性率５７７％。１２３例中６６例进行了病理学检查，观察到胃炎炎症程度与ＨＰ感染相关，６６例中胃窦粘膜活检正常６例，Ｇｉｅｍｓａ染色找菌ＨＰ全部阴性，轻度ＣＧ３７例Ｇｉｅｍｓａ染色ＨＰ阳性１１例（１１／３７），中重度２２例ＨＰ均为阳性。本组资料显示儿童ＲＡＰ多数存在器质性病变，并与ＨＰ感染有关。对非精神性ＲＡＰ、尤其血清ＨＰＩｇＧ抗体及胃液ＨＰＰＣＲ检测阳性者应进一步做胃镜检查以明确诊断。
Gastroscopy and Helicobacter pylori (HP) tests were performed in 123 children with recurrent abdominal pain (RAP) due to non-mental heart disease. Gastroscopy showed 17 cases (13.8%) of normal, 66 cases (53.7%) of chronic gastritis (CG), 13 cases (10.6%) of CG combined with duodenal inflammation and 4 cases of esophagitis (32%), peptic ulcer (PU) in 22 cases (179%) and pyloric stenosis in 1 case (08%). Three methods were used to detect HP: ELISA method, PCR and histological staining showed that the positive rate of HP was 577%. Among the 123 cases, 66 cases were pathologically examined. The degree of gastritis was found to be associated with HP infection. Sixty-six cases had a normal gastric mucosa biopsy, all were negative for Giemsa staining, and 11 were positive for CG37 with a Giemsa stain (11/37), moderate and severe 22 cases of HP were positive. This group of data show that most children with organic disease RAP, and with HP infection. On the non-spiritual RAP, in particular, serum HP IgG and gastric juice HP PCR test positive gastroscopy should be further done to confirm the diagnosis.
