[The tonus of Oddi's sphincter and gallbladder contractility in patients with chronic cholecystitis].

As many as 163 young male patients with chronic noncalculous cholecystitis were studied for motility of the biliary tract. Normal findings were in 15.9% of cases. Hypocontractility of the gallbladder, hypermyotonia of the Oddi sphincter (with 33.7% and 44.2% respectively), and concurrent presence thereof were the most commonly seen types of dyskinesia. The results obtained suggest that the above abnormalities in motility of the biliary tract may have a part in the origination and/or progression of chronic cholecystitis.
