Technic of extraction of hepatic duct calculi with modified Fogarty catheter and report of a case

Abstract: The biliary modification of the Fogarty balloon catheter has been employed successfully in the extraction of otherwise undetectable hepatic duct stones. The technic of extraction is described in detail. Replacement of the soft rubber tip by an equally small metal tip would enhance its benefit in detection of these calculi. In this manner, the catheter could be employed as a probe as well as an instrument for extraction.
