12-mm Partial Covered Versus Bare Self-Expandable Metallic Stents for Malignant Distal Biliary Obstruction
Condition(s) studied
Investigational drug(s) / intervention(s)
12-mm partially covered self-expandable metallic stent: A 12-mm partially covered self-expandable metallic stent placed through the existing percutaneous transhepatic biliary drainage (PTBD) tract for internal biliary drainage in patients with unresectable malignant distal biliary obstruction.
12-mm bare self-expandable metallic stent: A 12-mm bare self-expandable metallic stent placed through the existing percutaneous transhepatic biliary drainage (PTBD) tract for internal biliary drainage in patients with unresectable malignant distal biliary obstruction.
Study summary
Metallic stents are commonly used for biliary drainage in patients with unresectable malignant distal biliary obstruction. However, it is unclear whether a 12-mm partially covered self-expandable metallic stent or a 12-mm bare self-expandable metallic stent provides better effectiveness and safety. This prospective, randomized clinical trial will compare these two stent types in adult patients who have already undergone percutaneous transhepatic biliary drainage (PTBD) and are scheduled for metallic stent placement through the existing PTBD tract. A total of 60 participants will be enrolled. After stent placement, participants will be followed for 12 months, with assessments at 3, 6, and 12 months. The study will evaluate recurrent biliary obstruction, stent patency duration, reintervention, overall survival, and procedure-related complications. The results are expected to provide evidence for selecting the most appropriate 12-mm metallic stent for patients with unresectable malignant distal biliary obstruction.
Eligibility
Primary outcome measure(s)
- Cumulative incidence of recurrent biliary obstruction (RBO) within 12 months after the procedure — 12 months after the procedure
