[Types of microcirculation and laser therapy in chronic pancreatitis]

The aim of the study was to evaluate effect of low-intensity laser therapy (LILT) on systemic circulation in patients with chronic pancreatitis (CP) in the phase of exacerbation. 65 patients aged 36-77 years were divided into study (n = 20) and control (n = 45) groups. In addition, 30 healthy subjects were examined. Patients of the study group received drug therapy combined with intravenous blood or skin laser irradiation. Controls were treated with medicinal preparations alone. CP was diagnosed based on characteristic pain syndrome, compromised secretory function of the pancreas, results of laboratory and instrumental analysis. Microcirculation was studied by laser Doppler flowmetry with a LAKK-02 apparatus (Lazma, Russia). CP patients had heterogeneous microcirculation with a significantly increased frequency of its pathologic types (spastic, hyperemic, spastic-congestive). Major characteristics of microcirculation were significantly different from those in healthy subjects. Combination of drug therapy and LILT substantially improved microcirculation regardless of its hemodynamic type.
