[The use of sound waves in treating hypotonic dyskinesias of the extrahepatic biliary tract and duodenum].

The authors studied the effect of sonic waves on the motility of extrahepatic biliary tract and duodenum in 32 patients with hypotensive, hypokinetic dyskinesias. It was found that application of sound (the parameters are described in detail) on the region of the duodenum increased the frequency of contractions, medium biopotential, amplitude and tone of this organ to practically normal levels, resulted in normalization of the motility of extrahepatic biliary tract, favours decompression of the bile-excretory system.
