Reduced complication rates of percutaneous transhepatic biliary drainage with ultrasound guidance

We aimed to analyze the benefits of adding ultrasound (US) guidance to the standard fluoroscopically assisted percutaneous transhepatic biliary drainage (F-PTBD). We also performed a systematic literature review of success and complication rates of US-PTBD in a wide field of indications.

We evaluated a total of 81 US-PTBDs carried out in our institution, 74% of which were part of the management of malignancy. In addition, we compared our results with those of a total of 5,272 procedures (3,779 F-PTBD and 1,493 US-PTBD) reported in the literature.

US-PTBD was technically successful in 94% of attempts with a mean of 2.2 needle passes. Procedural success was achieved in 86% of cases. There were no procedure-related deaths or severe complications. Minor complications were catheter dislodgement (15%) as well as one case each of a porto-biliary fistula, hematoma, and biloma. A systematic review of the literature also showed that US-PTBD has a similar technical success rate to F-PTBD but lower median rates of severe early complications (0% versus 8%) and procedural death (0% versus 1%).

Given our results and our review of the literature, US-PTBD is as effective as F-PTBD and has significantly lower complication rates. US-PTBD should be preferred to F-PTBD. © 2017 Wiley Periodicals, Inc. J Clin Ultrasound 45:400-407, 2017.
