METHOD FOR PREDICTING MOTOR-EVACUATORY FUNCTION OF GALLBLADDER IN CHILDREN Russian patent published in 2007 - IPC A61B8/00 

FIELD: medicine, pediatrics.

SUBSTANCE: it is necessary to conduct ultrasound studying of a patient's gallbladder since the moment of cholagogue breakfast intake at constant mode till the beginning of its contraction. Moreover, every minute it is important to make the organ's measurements: estimate its volume, fix its maximal volume and the moment of its maximal increase. Then, since the onset of gallbladder's contraction the investigations should be carried out every 8-10 min to fix its minimal volume and the moment of maximal contraction, detect the volume of excreted bile since the moment of maximal increase till the moment of gallbladder's maximal contraction according to the difference between its maximal and minimal volumes. Then one should detect volumetric expenditure of excreted bile by the following formula: Q=^V/t/α, where Q - volumetric expenditure in cu. cm/min, V - the volume of excreted bile in cu. cm; t - the time for bile excretion since the moment of maximal increase till the moment of gallbladder's maximal contraction in min; α - a correction coefficient in measuring units of accepted cholagogue breakfast. According to the value of volumetric expenditure of excreted bile and time necessary for its excretion one should diagnose the state of motor-evacuatory function of a patient's gallbladder. At the values ranged 0.14-0.26 cu. cm/min and 20-50 min, correspondingly, one should diagnose normal function of the gallbladder, at below 0.14 cu. cm/min and below 20 min - hypermotor function, at above 0.26 cu. cm/min and above 50 min - hypomotor function. The innovation enables to objectively predict, differentiate the norm and the character of disorder towards either hypo- or hypermotor dyskinesia.

EFFECT: higher accuracy of diagnostics.
