[Attempt at evaluation of certain parameters of gastric secretion in patients with duodenogastric reflux].

There were four groups of patients: duodenal ulcer patients (32), duodeno-gastric reflux patients (31), patients with duodenal ulcer and reflux (33) and 12 healthy men. All of them aged 20-40. In all patients we performed gastroscopy, cholecystography, Kay's test for secretion and isotope proteolytic secretion test. High activity of proteolytic secretion in both groups of reflux patients was found. There were also the high percentage of false positive scores in endoscopy estimation of reflux, in comparison to the non-invasive isotope method. We suggest: reflux may be the important factor in duodenal ulcer pathogenesis; endoscopy cannot be used in duodeno-gastric reflux estimation.
