RETAINED biliary stones following common bile duct exploration continue to bother the surgeon, and although it is difficult to obtain accurate estimates of incidence, it is known to be considerable.1 The incidence of retained stones rises sharply where cystic dilatation of intrahepatic or extrahepatic ducts has occurred; some of these patients have to undergo repeated operations for removal of retained concretions. It occurred to us to explore the feasibility of constructing temporary conduits from the dilated common bile duct to the skin of sufficient size that exploration of the duct could be carried out without resorting to laparotomy. Since the success of this endeavor would depend on the size of the conduit and the healing of the duct following removal, the experiment was designed for maximum size conduits.
Procedures and Techniques
Healthy mongrel dogs were used for experimental animals. The experiment was carried out in three stages.
