[Stages of duodenal motility disorders in the formation of duodenogastric reflux in patients with chronic duodenitis complicated by opisthorchiasis].

Stages of the duodenogastral reflux development in the patients with chronic duodenitis with opistorchosis combination are presented as follows. The 1st stage manifests the earliest attributes of duodenal passage changes that are revealed with duodenodebitometria (the definition of physiologogical solution perfusion speed in duodenum). Structural changes are absent in this stage. The compensated changes of duodenal passage, so called "latent" and later stable duodenal hypertension are demonstrated in the patients with the 2nd stage. The patients with duodenal hypertension and nonstable duodenal regurgitation constitute the 3rd stage. The 4th stage is presented with subcompensated duodenal passage changes, that later transform to the decompensated ones with stable duodenal reflux into a stomach development.
