The Hemodynamic Changes of Gastroduodenal Regional Blood Flow after Helicobacter Pylorieradication in patients with Duodenal Ulcer Scar
十二指腸潰瘍瘢痕期病人根除幽門螺旋桿菌後之胃十二指腸局部血流變化
摘要
Duodenal ulcer (DU) is frequently accompanied by Helicobacter pylori (HP) infection and associated with the imbalance of aggressive factors and defensive factors. To investigate the possible relationship between Hp and regional gastric blood flow, 26 endoscopically proved DU (scar stage) and Hp infection patients were included and received triple therapy (colloid bismuth subcitrate 120 mg qid for 4 weeks, amoxicillin 500 mg qid for 2 weeks and metronidazole 250 mg tid for 2 weeks). Regional gastroduodenal blood flow (RGDF) was measured at DU scar area and antrum lesser curvature site by laser Doppler flowmetry during endoscopic examination, before and one month after triple therapy. In 22 patients with Hp eradication the RGDF was significantly elevated at antrum lesser site after triple therapy (p ＜ 0.05) but there was no difference at DU scar area. However, in 4 patients without Hp eradication no difference of RGDF in these two points was found. Therefore, Hp appears to have direct effects on gastric microcirculation.
