Abstract

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. 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.
