Summary
EUS-guided transhepatic biliary drainage (ETBD) is an effective treatment for benign and malignant biliary obstruction, even in patients with surgically altered anatomy. This U.S. single-center study shows high success rates and a manageable adverse event profile for ETBD.
Area of Science:
- Gastroenterology
- Interventional Endoscopy
- Biliary Interventions
Background:
- EUS-guided hepaticogastrostomy, now termed EUS-guided transhepatic biliary drainage (ETBD), has international experience.
- ETBD offers access to intrahepatic bile ducts via various luminal and biliary approaches.
- This study presents the largest U.S. single-center experience with ETBD.
Purpose of the Study:
- To evaluate the efficacy and safety of ETBD in managing benign and malignant biliary diseases.
- To assess ETBD outcomes in patients with native and surgically altered anatomy.
- To report the largest U.S. single-center experience with ETBD.
Main Methods:
- Retrospective analysis of ETBD procedures performed by a single endoscopist from September 2014 to May 2021.
- Inclusion of 215 patients with benign (n=85) and malignant (n=130) biliary obstruction.
- Data collection on patient demographics, anatomy, procedural details, success rates, adverse events, and follow-up.
Main Results:
- Technical success rate of 95.3% and clinical success rate of 87.25% in 215 attempted ETBD procedures.
- High prevalence of surgically altered anatomy (43%) and prior failed endoscopic attempts (43%).
- Modest adverse event rate (18.6%), with 34.4% mortality in the malignant cohort during follow-up.
Conclusions:
- ETBD is a viable and effective treatment for biliary obstruction in patients with both native and surgically altered anatomy.
- The procedure demonstrates a favorable balance of efficacy and safety.
- ETBD offers a valuable therapeutic option for complex biliary interventions.
