Usefulness of a Percutaneous Transhepatic Coaxial Micropuncture Needle Technique in Patients with Nondilated Peripheral Intrahepatic Ducts

This is the authors' abstract. We don't add key points for this paper.

OBJECTIVE: I sought to develop an efficacious transhepatic technique for localizing normal or minimally dilated biliary radicles using 25- to 27-gauge needles threaded through 21- to 22-gauge needles. CONCLUSION: The micropuncture needle is a useful adjunct for performing transhepatic cholangiography in patients whose bile ducts are nondilated or in whom the standard transhepatic needle technique has failed.
