Modified single step ultrasound guided percutaneous transhepatic biliary drainage (MSSUGPTBD): experience with 102 patients.

ABSTRACT

Modified single step ultrasound guided percutaneous transheptic biliary drainage was performed in 102 patients between 1993 and 1998 at the National Cancer Institute, Bangkok with successfully placed drainage tubes in the dilated bile ducts. The advantages of this technique are single step puncture without major complication or bleeding, reduction of radiation exposure, capability for bile duct selection and time saving.
