膽汁反流性胃炎(bile reflux gastritis)亦稱堿性反流性胃炎 ,是炎伴指由於幽門括約肌功能失調或胃幽門手術等原因造成含有膽汁 、胰液等十二指腸內容物流入胃,胆汁的症使胃黏膜產生炎症 、反流糜爛和出血 ,減弱胃黏膜的屏障功能,引起H+彌散增加,而導致胃黏膜慢性病變。
膽汁反流性胃炎的病因主要為胃大部切除、胃空腸吻合術後 ,以及幽門功能失常和慢性膽道疾病,細菌(尤其是幽門螺杆菌)感染 、胃酸 、膽汁等損害胃黏膜造成炎症,增加胃泌素釋放 ,影響胃十二指腸動力 ,導致胃-幽門-十二指腸協調運動失調,引起十二指腸逆蠕動增加、幽門關閉功能減弱、胃排空延遲,使得十二指腸內容物過量反流入胃。

任何導致胃腸動力的紊亂,如胃腸神經肽和激素水平異常可使胃腸道運動紊亂,解剖異常的因素,如原發性幽門括約肌功能障礙可使幽門開放時間延長 、幽門鬆弛或持續開放狀態 ,均可發生病理性十二指腸胃反流。
