Abstract

Duodenal and gastric contents do reflux into the oesophagus and acid alone certainly causes oesophageal damage which will be worsened by pepsin. In the patient who has undergone gastrectomy duodenal secretions may also be harmful. There is evidence that when the two mix there may be a toxic synergism, leading to mucosal disruption and intracellular damage to oesophageal cells which produces the clinical picture of reflux oesophagitis, with or without symptoms. Clear evidence of the toxicity of duodenal refluxate in humans is lacking, but the ability to measure bile and acid reflux continuously, together with a method of detecting oesophageal damage at a cellular level should help to solve this long debated problem.

摘要

十二指肠和胃内容物确实会反流至食管,仅胃酸就肯定会造成食管损伤,而胃蛋白酶会使这种损伤加剧。在接受过胃切除术的患者中,十二指肠分泌物也可能有害。有证据表明,当二者混合时,可能会产生毒性协同作用,导致黏膜破坏和食管细胞的细胞内损伤,从而出现反流性食管炎的临床表现,无论有无症状。目前缺乏十二指肠反流物对人体有毒性的确切证据,但能够连续测量胆汁和胃酸反流,以及在细胞水平检测食管损伤的方法,应该有助于解决这个长期存在争议的问题。
