Percutaneous catheterization of the gallbladder with ultrasonic guidance

We have described a case in which the gallbladder was catheterized by the Seldinger technic, using ultrasonic guidance. The biliary tree was flushed until clear and free passage of bile into the duodenum occurred. Thick inspissated bile can cause intrinsic echoes in the gallbladder that can be mistaken for gallstones.
