Reduced complication rates of percutaneous transhepatic biliary drainage with ultrasound guidance

This is the authors' abstract. We don't add key points for this paper.

BACKGROUND: 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. METHODS: 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. RESULTS: 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%). CONCLUSIONS: 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.
