Insights

Endoscopic ultrasound-guided intrahepatic biliary drainage (EUS-IBD) demonstrates high success and safety, particularly for complex cases. EUS-IBD shows superiority over percutaneous drainage (PTBD) in treating proximal strictures and altered anatomy.

Area of Science:

  • Gastroenterology
  • Interventional Endoscopy
  • Biliary Interventions

Background:

  • Endoscopic ultrasound-guided intrahepatic biliary drainage (EUS-IBD) is underutilized compared to percutaneous drainage (PTBD).
  • Limited data exists for EUS-IBD in hilar stenoses or postsurgical anatomy.
  • This study evaluates EUS-IBD techniques and compares them to PTBD in challenging cases.

Purpose of the Study:

  • To assess the efficacy and safety of different EUS-IBD techniques (Rendez-vous, antegrade stenting, hepatico-gastrostomy).
  • To compare EUS-IBD with PTBD in patients with proximal biliary stenosis or surgically altered anatomy.
  • To evaluate outcomes including technical/clinical success, adverse events, and reinterventions.

Main Methods:

  • Retrospective analysis of 104 EUS-IBD procedures (2012-2019).
  • Comparison of Rendez-vous, antegrade stenting, and hepatico-gastrostomy.
  • 1:1 matched comparison of EUS-IBD versus PTBD for proximal stenosis/altered anatomy.

Main Results:

  • High technical (89.4%) and clinical success (96.2%) for EUS-IBD.
  • Hepatico-gastrostomies with dedicated stents were shorter and showed a trend towards less dysfunction.
  • In complex cases, EUS-IBD achieved higher clinical success (97.4% vs. 79.5%), less pain, shorter hospital stays, and fewer reinterventions compared to PTBD.

Conclusions:

  • EUS-IBD is a safe and effective procedure with high success rates.
  • Hepatico-gastrostomy outcomes are comparable and may improve with specialized tools.
  • EUS-IBD is superior to PTBD for managing proximal biliary strictures and surgically altered anatomy.
