本文对43例溃疡病胃切除患者和8例健康对照者进行空腹厌氧菌等定量培养研究,发现B-Ⅱ组的肠道菌(肠道厌氧菌和肠杆菌)检出率明显高于B-Ⅰ组。而PAFPG组未检出肠道菌;并且胃液总菌数、硝酸盐还原菌数,肠道菌数和pH等指标,B-Ⅱ和B-Ⅰ组明显高于PAFPG组或对照组。提示传统胃大部切除术后存在着胃内细菌过度生长(IBO),但PAFPG降酸适中,IBO不明显。
In this study, fasting anaerobic bacteria and other quantitative culture studies were performed on 43 cases of gastric ulcer resection patients and 8 healthy controls. The detection rate of intestinal bacteria (intestinal anaerobes and enterobacteria) was significantly higher in the B-II group. Group B-I. In the PAFPG group, intestinal bacteria were not detected; and the total number of gastric juice, nitrate-reducing bacteria, intestinal bacterial count and pH were significantly higher in the B-II and B-I groups than in the PAFPG group or the control group. It is suggested that there is intragastric bacterial overgrowth (IBO) after traditional subtotal gastrectomy, but PAFPG is moderately acid-reducing and IBO is not obvious.
