Manometry with needle cholangiography. Results in 70 patients

Cholangiomanometry is evaluated in 70 patients using a new technique based on needle cholangiography. In 94% of the patients the results of cholangiomanometry were in agreement with the final operative diagnosis. In two patients out of 20, common duct stones did not cause changes in the biliary pressure. In 14 patients re-operated on for postcholecystectomy pains, the increase in intrabiliary pressure due to a fentanyl dose was significantly higher than that in the control patients. Cholangiomanometry is recommended for selective use to complement needle cholangiography in biliary re-operations and in operations after biliary pancreatitis.
