[Possibilities of the treatment of biliary dyskinesia by laser irradiation].

The examination of 68 patients with biliary dysfunction determined hypokinesia of the gallbladder in 40, sphincter of Oddi spasm in 15 and combination of the two conditions in 13 patients. Blood biochemical indices showed no differences in patients with biliary dyskinesia compared to normal subjects except for alkaline phosphatase levels elevated in 35.3% of patients. This suggests the development of biliary hypertension and cholestasis. All the patients demonstrated disturbed colloid stability of the bile, in those with combined dyskinesia it became lithogenic. Helium-neon and semiconductor laser radiation of biologically active points and the hepatic region, respectively, improved the patients' performance status. The pain and dyspepsia discontinued. The function of the gallbladder and sphincter of Oddi recovered. Positive changes occurred in the blood and bile biochemistry. Laser therapy promoted bilirubin and bile cholesterol decrease. Cholic acid concentration grew, lithogenic characteristics of the bile returned to normal. It is inferred that laser therapy of biliary dyskinesia proved effective.
