Fasting and peak postprandial bile acid concentrations in the stomach were low in all normal controls. Although high concentrations were found in many patients with GU (P&amp;lt;0\u00b701), similar concentrations were found in many patients with radiologically non-functioning gallbladders containing gallstones (NFG) (P&amp;lt;0\u00b701) and also after cholecystectomy (AC) (P&amp;lt;0\u00b701). Fasting intragastric phospholipase A2 activities were similar, and very high in GU and NFG patients compared with control subjects (P&amp;lt;0\u00b701). High values were not found after cholecystectomy. There was no difference in pH profile or in postprandial phospholipase A2 between patient groups. Since patients with cholelithiasis or after cholecystectomy are not known to have an increased incidence of gastric ulceration, the significance of duodenogastric reflux in the aetiology of gastric ulcers must be questioned. If reflux does produce ulcers in GU patients then factors in addition to bile acid are probably involved. However, neither patterns of phospholipase A2 reflux nor pH profiles can explain the absence of gastric ulceration in those patients with gallstones who reflux large quantities of bile acid.<\/jats:p>","DOI":"10.1002\/bjs.1800740823","type":"journal-article","created":{"date-parts":[[2007,3,3]],"date-time":"2007-03-03T10:19:16Z","timestamp":1172917156000},"page":"721-725","source":"Crossref","is-referenced-by-count":10,"title":["Relative
