title: [Ulcer disease and duodenogastric reflux].
abstract: The intragastric concentrations of lysolecithin and bile acids were determined in 44 chronic peptic ulcer patients and 35 healthy volunteers. Normal reflux values were found in the prepyloric ulcer (Johnson type III) (n = 15) Elevated reflux amounts could be observed in the type I gastric ulcer (n = 15), there was a three-to fourfold increase compared to the controls. - Slightly elevated reflux concentrations were found in the duodenal ulcer patients (n = 14), but only under fasting conditions. The increase of reflux concentration in chronic gastric ulcer type I is shown to be in the same range as in acute stress ulcer. Compared to the three-to four times higher reflux concentrations of the resected stomach, the duodenogastric reflux in ulcer disease is very moderate. It's role in ulcerogenesis has to be analyzed further.
