Summary
Percutaneous transhepatic biliary drainage (PBD) effectively manages malignant biliary obstructions. Internal endoprostheses are preferred over external drains due to fewer complications.
Area of Science:
- Interventional Radiology
- Gastroenterology
- Oncology
Background:
- Malignant biliary obstructions pose significant clinical challenges.
- Percutaneous transhepatic biliary drainage (PBD) is a key intervention for managing these obstructions.
Purpose of the Study:
- To describe the experience with PBD in malignant biliary obstructions.
- To compare the outcomes of different PBD techniques.
Main Methods:
- Review of 78 PBD procedures in 68 patients with malignant biliary obstructions.
- Procedures included external drains, internal-external drains, soft endoprostheses, and self-expandable metallic stents.
- Data collected on procedural outcomes and complications.
Main Results:
- No significant difference in outcomes between internal endoprostheses and metallic stents.
- Procedure mortality rate was 1.47% (1 case).
- Complications for internal prostheses included obstructions (25.8%), dislodgement (6.5%), cholangitis (3.2%), and metastases (3.2%).
Conclusions:
- Internal endoprostheses are favored over external or internal-external drainages for PBD in malignant biliary obstructions.
- Careful consideration of complication rates influences the choice of drainage method.
