This report describes a newly developed catheter system with the aid of which the cystic duct and gallbladder can be reliably catheterized, retrograde, via an endoscope. In 8 out of 10 autopsy preparations, transpapillary gallbladder catheterization was successfully achieved, with an average fluoroscopic duration of 12 minutes (range: 4-20 minutes). Neither macroscopic nor microscopic traumatization of the gallbladder was observed. The procedure described in this paper opens up a diagnostic and therapeutic approach to the gallbladder.
