ESTIMATION OF VASCULAR TONUS REGULATION IN PATIENTS WITH BILIARY-DEPENDENT PANCREATITIS

Aim. To study the state of systemic and regional microcirculation in patients with biliary-dependent pancreatitis. Materials and methods. 12 patients with biliary-dependent pancreatitis were examined. Besides the standard methods of examination, rheohepatography and precision thermometry was performed. Results. In practically healthy persons, skin temperature amplitudes are reliable decreased in response to cold stress, but after its termination they restore till the initial values during three minutes. In biliary pancreatitis, skin temperature fluctuations in endothelial frequency range fall during the cold test and do not change later on. In neurogenic and myogenic frequency ranges, skin temperature fluctuations decrease during the pressor test and restore to the initial values by the 10 th minute after the test. Endothelial and neurogenic disregulation of vascular tonus is associated with disturbances of regional circulation and serves as one of risk factors for development of pancreatogenic hepatic and renal dysfunction. Disturbance of endothelial vasoregulation system is closely connected with hemorheological changes in blood. Conclusion. Development of biliary-dependent pancreatitis is accompanied by endothelial dysfunction and decrease in activity of neurogenic and myogenic mechanisms of vascular tonus regulation.
