Single-Wall Puncture: A New Technique for Percutaneous Transhepatic Biliary Drainage

The purpose of our study is to evaluate the safety and utility of a new single-wall puncture technique for percutaneous transhepatic biliary drainage in comparison with the conventional double-wall puncture technique. Our results suggest that the single-wall puncture technique is a useful method for percutaneous transhepatic biliary drainage and may be safer than the conventional double-wall puncture technique.
