目的:分析肠易激综合征(IBS)患者小肠细菌过度生长(SIBO)情况。方法:选取正常对照30人;腹泻型-IBS(IBS-D)30人,便秘型-IBS(IBS-C)患者30人;测定小肠细菌过度生长情况,并将结果加以比较。结果:(1)IBS-D组SIBO发生率47.7%,IBS-C组SIBO发生率43.3%,正常对照SIBO发生率6.7%组,IBS组的SIBO发生率高于正常对照组(P<0.05)。意义:(1)肠易激综合征患者中有较高的SIBO发生率。
Objective: To analyze the intestinal bacterial overgrowth (SIBO) in patients with irritable bowel syndrome (IBS). Methods: 30 normal controls, 30 IBS-IB patients and 30 IBS-C patients were enrolled in this study. The intestinal bacterial overgrowth was measured and the results were compared. Results: (1) The incidence of SIBO in IBS-D group was 47.7%, the incidence of SIBO in IBS-C group was 43.3%, the incidence of SIBO in normal control group was 6.7%, and the incidence of SIBO in IBS group was higher than that in normal control group (P <0.05) . Significance: (1) Patients with irritable bowel syndrome have a higher incidence of SIBO.
