摘要
肠易激综合征（IBS）是一种常见的功能性胃肠病,其发病机制复杂.目前认为IBS与胃肠动力障碍、内脏高敏感、肠道感染、脑-肠轴功能紊乱、免疫活化等因素有关.最新研究表明小肠细菌过度生长（SIBO）在IBS的发病中亦起重要作用.本文就SIBO在IBS中的研究进展,包括病理生理机制、诊断、治疗等作一综述.
Irritable bowel syndrome （IBS） is a common gastrointestinal disorder with complicated mechanisms. Several factors have been identified as etiological factors of IBS, such as altered gastrointestinal motility, visceral hypersensitivity, intestinal infection, abnormal brain-gut interaction and immunological activation, etc. Recent studies have shown that small intestinal bacterial overgrowth （SIBO） also plays an important role in the pathogenesis of IBS. This article reviewed the advances of studies on SIBO in IBS, including pathophysiologic mechanisms, diagnosis and treatment.
