title: [Pathogenesis and significance of gastroduodenal reflux].
abstract: For over a century duodenogastric reflux (DGR) has been considered the main cause of the primary or secondary alkaline gastritis. In the first case it occurred in patients who had not been operated earlier, in the latter one in those after surgery of stomach, duodenum, gallbladder and bile ducts. Since first time many reports of clinical and experimental studies have demonstrated destructive effect of pancreatic enzymes, bile acids and their by-products on stomach mucose producing in consequence non-specific histologic lesions. It has been also observed that duodenogastric reflux plays the basic role in the patho-genesis of gastritis and other GI tract diseases (gastric ulcer, reflux oesophagitis, progressing metaplasia or oesophageal and gastric cancer). As far as diagnosing of alkaline gastritis requires histologic confirmation, duodenogastric reflux brings many more problems. However, the progress in medicine and technology allow direct measurement of quality and quantity of this reflux.
