Abstract
- PURPOSE
To evaluate the usefulness of percutaneous transhepatic biliary drainage (PTBD) tract dilatation using a Nipro set.
MATERIALS AND METHODS
We dilated 28 percutaneous biliary drainage tracts up to 18F ; 26 procedures involved PTBD, and two, cholecystostomy. A Nipro set was used for dilatation, the purposes of which were stone removal (n=18) and choledochoscopic biposy (n=10). For dilatation, local anesthesia was used in all cases.
RESULTS
In all patients, tract dilatation was successful. In 21 of 28 cases, dilatation of the right PTBD tract was involved, and in five of 28, dilatation of the left tract. In two cases, tract dilatation was done in cholecystostomy tracts. Complications encountered were pain (n=17), bradycardia (n=2), hemobilia (n=2), bleeding (n=1)and fever (n=1).
CONCLUSION
In choledocoscopy, tract dilatation using a Nipro set is safe and simple.
