METHOD FOR DIAGNOSIS OF BILE OUTFLOW DISORDERS Russian patent published in 2022 - IPC A61B6/00 G01T1/164 A61K51/00 A61K103/10 A61B5/00 A61P1/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to medical radiology, oncology, surgery, gastroenterology. 0.5-1.0 ml of Bromezida imaging agent containing 150 MBq of the isotope ^99mTc is administered intravenously. The speed of movement of bile through the ducts and the speed of passage of bile through the anastomosis is determined for 60 minutes using a gamma camera detector located above the liver area. A frame is selected on the received scintigrams, where the bile labeled with the radiopharmaceutical enters the discharge loop. Two equal-volume zones of interest above and below the level of the anastomosis are determined as well as the count of pulses above these zones in a particular patient according to the original formula. A value of 1.0 corresponds to the absence of a biliodynamically significant obstacle in the passage of bile through the zone of biliodigestive anastomosis; a value of 0.001-0.99 corresponds to the presence of a biliodynamically significant obstacle in the passage of bile through the zone of biliodigestive anastomosis.

EFFECT: method makes it possible to increase the accuracy of visualization of the movement of bile along the intrahepatic bile ducts through a biliodigestive anastomosis, to determine the tactics of treatment and indications for surgical intervention.
