REGIONAL HEMODINAMICS IN CASE OF CHRONIC CHOLECYSTITIS AND OTHER GALL-BLADDER CONDITIONS WITHOUT CHRONIC INFLAMMATION ACCORDING TO DOPPLER SONOGRAPHY
The aim of the study was to develop differential criteria based on regional hemodynamic changes via Color Doppler and Power Doppler scanning in case of chronic calculous cholecystitis, chronic acalculous cholecystitis and conditions of the gallbladder with no signs of a chronic inflammatory process in the wall. The results indicate low values of peak systolic flow velocity in the gallbladder wall by reason of increased rigidity of arterial walls and intravascular pressure in patients with chronic calculous cholecystitis, in contrary to acalculous cholecystitis and other non-inflammatory changes of the organ. The use of the complex of Doppler indicators of hemodynamic disturbances in gallbladder wall allows us to differentiate a degree of organ fibrosis in chronic inflammatory processes. Also in cases of cholecystolithiasis this approach makes possible to differentiate stones “carriage” without requiring cholecystectomy (according to the Rome selection criteria for surgery in patients with cholelithiasis), and chronic calculous cholecystitis with significant indications for cholecystectomy.
