A suitable artificial conduit to replace a diseased or damaged common duct segment is not currently available. In the experimental laboratory a variety of materials have failed when used either as permanent channels or as extractable prostheses.1 Cicatricial stenosis, occluding stone formation, implant rejection, and functional obstruction have thrwarted attempts to develop a satisfactory bile duct substitute for clinical application.

Previous experience with a biologically nonreactive, conductive hydrophilic polymer (Hydron) suggested its use for bridging defects in the extrahepatic biliary system. Since this material is capable of absorbing water-soluble ions to equilibrium, it appeared that a compatible bile plastic interface could be established to inhibit stone formation.2 Molded, multisized, supple cylinders of the synthetic seemed to possess sufficient body to resist the stenosing effects of the scarring commonly encountered in the region of the porta hepatis. This report deals with the use of Hydron as a canine-common bile
