新的胃炎分类法——悉尼系统是一套高度灵活的分类系统,将以往不同分类法统一起来,具有广泛的应用价值。该系统包括组织学分类和内镜分类两大部分。组织学分类由病因、病变部位和病理形态三部分组成。按病理形态将胃炎分为急性、慢性和特异性三大类。对炎症、活动性、萎缩、肠上皮化生和幽门螺旋菌五项主要病变程度分成无、轻、中及重四个级别。病变部位要注明胃窦、胃体或全胃。病因包括幽门螺旋菌、自身免疫、药物及特发性等。内镜分类是对胃粘膜炎症特征作分级描述并注明部位,据此将胃镜胃类归纳为红斑渗出性、平坦糜烂性、隆起糜烂性、萎缩性、出血性、返流性及肥厚性等类型。文章最后对微生物及免疫因素的重要性及胃炎的自然病程和预后作了简要介绍。
