METHOD FOR DIFFERENTIAL DIAGNOSTICS OF ANTRODUODENAL COORDINATION Russian patent published in 2006 - IPC A61B8/00 A61K49/04 

FIELD: medicine, gastroenterology.

SUBSTANCE: one should study motor-evacuation activity of gastroduodenal transition, carry out ultrasound investigation including the introduction of a contrast followed by scanning a longitudinal section of antroduodenal area. On registering the onset of contrast evacuation out of stomach into the upper-horizontal duodenal part one should start counting the number of peristaltic waves in antral gastric department for 180 sec, then a pick-up unit should be replaced under the lower hepatic edge into projection area of the upper-horizontal duodenal part to count the number of peristaltic waves in duodenum during 180 sec at subsequent detection of the coefficient for antroduodenal coordination by the following formula: C=Pa/Pd, where C - coefficient of antroduodenal coordination, Pa - the number of peristaltic waves in antral gastric department, Pd - the number of peristaltic waves in duodenum, and at coefficient value of antroduodenal coordination being 0.25-0.33 one should detect the norm, at the value being above 0.33 one should detect hypokinetic variant of disorders in antroduodenal coordination and at the value being below 0.25 it is possible to detect hyperkinetic variant of disorders in antroduodenal coordination.

EFFECT: higher efficiency for differential diagnostics.
