摘要 近年来,胃食管反流性疾病(GERD)发病日趋增多。经过24h食管PH监测发现,正常健康者均有胃食管反流(GER)现象,但无任何临床症状,称之为生理性GER。其特点为白天常发作,夜间罕见;餐时或餐后反流较多,其反流总时间每24h少于1h。由于反流物可即刻被清除到胃内,一般并不致病。但是当食管下段括约肌(LES)抵抗GER的屏障功能削弱时,会导致频繁GER,反流物量多且较持久,从而损伤食管下段粘膜,形成反流性食管炎,并能引起食管溃疡和狭窄,这些统称GERD。Sandmark在内镜下把食管炎分为5级:0级,正常食管粘膜;1级,食管粘膜充血,水肿;2级,粘膜点状糜烂;3级,糜烂融合或溃疡形成;4级,食管四周糜烂及形成深部溃疡,狭窄和/或Barret食管形成。目前临床上对GERD的治疗方法很多,但最佳方案是以内镜改变为基础,进行阶段性治疗。
