since , however , it is not possible to arrive at a quantitative and qualitative assessment of the reflux via roentgenology , the aim of radiological examination in case of clinical suspicion of reflux is to determine a ) the factors favouring reflux , ie hiatal hernia , gastric and duodenal ulcer , stenosis of the pylorus , etc , b ) the sequelae of a pathological reflux , eg reflux stenosis , reflux ulcer , brachyosophagus etc , as well as c ) to assess the self-cleaning function of the osophagus .
