原发性胆汁反流性胃炎诊断的探讨

目的　探讨原发性胆汁反流性胃炎的诊断方法及十二指肠胃反流 (DGR)的临床意义。方法　用便携式胆红素监测仪 (Bilitec2 0 0 0 )对 2 0例健康人及 42例有腹痛、腹胀、恶心及呕吐胆汁等症状的非溃疡性消化不良患者进行 2 4h胃内胆红素监测、临床症状评分、胃镜检查及组织活检。分析DGR的严重度与症状、内镜所见和组织学改变之间的关系。结果　 2 4h胆汁反流总时间百分率在健康组和有症状组中分别为 (2 92± 2 39) %及 (1 7 68± 1 7 89) % (P <0 0 1 ) ,病理性DGR的检出率为55 %。内镜下黏液湖胆染、胃窦黏膜糜烂、胆染伴胃窦黏膜糜烂、胆染伴中度以上的充血者中病理性DGR的检出率分别为 86 %、88%、8/8、85 %。内镜检查发现黏液湖胆染和胃窦黏膜糜烂和 (或 )中度以上充血并被Bilitec2 0 0 0证实存在病理性DGR的胆汁反流性胃炎 (BRG)者共有 1 1例。幽门螺杆菌(Hp)阴性的BRG者 ,组织学上活动性炎症比生理性DGR组Hp阴性者严重 (P <0 0 5)。各项临床症状的发生率在各组间差异无显著性 (P值均 >0 0 5) ,但BRG组腹胀、恶心及呕吐胆汁等症状的严重程度显著重于生理性DGR组 (P值均 <0 0 5)。结论　完整胃内镜检查发现黏液湖胆染同时伴胃窦黏膜糜烂和 (或 )中度以上充血并被Bilitec2 0 0 0证实存在病理性DG

A study of diagnosis of primary biliary reflux gastritis

OBJECTIVE: To study the diadynamic method of primary bile reflux gastritis. METHODS: Endoscopy, histologic examination, symptom analysis and 24-hour gastritic bilirubin monitoring with Bilitec 2000 were performed in 20 healthy subjects (HS) and 42 patients with symptoms of abdominal pain, abdominal distention, nausea and bile vomiting. RESULTS: The total fraction time of bile reflux was higher in 42 patents than in 20 HS [(17.68 +/- 17.89)% vs. (2.92 +/- 2.39)%, P < 0.01]. 23 (55%) of 42 patients showed pathologic duodenogastric reflux (DGR). The incidence of pathologic DGR detected by Bilitec2000 in bile dyed mucous lake, antral mucosal erosion, bile dyed mucous lake accompanied with erosion and bile dyed mucous lake accompanied with middle-hyperemia of antral mucosae found in endoscopy were 86%, 88%, 8/8 and 85% respectively. The diagnosis of bile reflux gastritis (BRG) could be established if the patients with bile dyed mucous lake accompanied with erosion and/or middle-hyperemia of antral mucosae were found to be pathologic DGR. With this criterion, 11 patients were BRG in 42 patients in this study. The active inflammation of antral mucosae in the patients with BRG that without Helicobacter pylori (Hp) infection was more severe than that in the patients with physiologic DGR that without Hp infection significantly (P < 0.05). The symptoms of abdominal distention, nausea and bile vomiting in the patients with BRG were more severe significantly than those in the patients with physiologic DGR respectively (P < 0.05). CONCLUSIONS: Final diagnosis of BRG can be made for the integrity stomach if the patients with bile dyed mucous lake accompanied with erosion and/or middle-hyperemia of antral mucosae were found to be pathologic DGR by Bilitec 2000.
