Summary
Embolizing transhepatic tracts after biliary intervention is feasible and prevents bile leakage. However, reobstruction can lead to complications like biliocutaneous fistulas, indicating the need for ongoing monitoring.
Area of Science:
- Interventional Radiology
- Gastroenterology
- Biliary Interventions
Context:
- Percutaneous transhepatic biliary interventions are common for biliary obstruction.
- Transhepatic tracts pose a risk of bile leakage and peritonitis.
- Effective methods to seal these tracts are needed.
Purpose:
- To evaluate the feasibility and efficacy of embolizing transhepatic tracts after intervention.
- To prevent peritoneal bile leakage following percutaneous transhepatic biliary interventions.
Summary:
- Twenty patients with biliary obstruction underwent percutaneous transhepatic biliary intervention followed by tract embolization using Histoacryl-Lipiodol.
- Embolization was feasible in all patients, creating a continuous cast of the tract.
- No peritonitis was observed; one patient developed a biliocutaneous fistula after 60 days due to stent occlusion.
Impact:
- Transhepatic tract embolization is a safe and effective method to prevent immediate bile leakage.
- The technique provides a temporary seal, highlighting the importance of managing biliary reobstruction to ensure long-term patency and prevent delayed complications.
