Summary
Unilateral radioactive stent (RS) insertion offers longer stent patency and improved survival for hilar cholangiocarcinoma (HC) patients compared to bilateral normal stents (NS). Both methods show similar safety profiles and technical success rates.
Area of Science:
- Interventional Gastroenterology
- Oncology
- Biliary Interventions
Background:
- Hilar cholangiocarcinoma (HC) presents complex treatment challenges, often requiring palliative biliary drainage.
- Stent placement is a common intervention for managing biliary obstruction in inoperable HC.
- Comparing radioactive stents (RS) with normal stents (NS) is crucial for optimizing patient outcomes.
Purpose of the Study:
- To compare the clinical efficacy and safety of unilateral radioactive stent (RS) insertion versus bilateral normal stent (NS) insertion.
- To evaluate outcomes in patients with inoperable hilar cholangiocarcinoma (HC).
Main Methods:
- A comparative analysis of patients with inoperable HC treated between January 2016 and December 2020.
- Two groups were analyzed: unilateral RS insertion and bilateral NS insertion.
- Efficacy and safety parameters including technical success, clinical success, restenosis, stent patency, overall survival, and complications were assessed.
Main Results:
- Technical and clinical success rates were comparable between unilateral RS (98.3%, 98.2%) and bilateral NS (94.7%, 100%) groups.
- No significant difference in stent restenosis or postoperative complications was observed between the groups.
- Unilateral RS insertion resulted in significantly longer stent patency (202 vs. 119 days) and overall survival (229 vs. 122 days) compared to bilateral NS.
Conclusions:
- Both unilateral RS and bilateral NS insertion demonstrate favorable therapeutic efficacy for inoperable HC.
- Unilateral RS insertion provides superior stent patency and overall survival benefits compared to bilateral NS.
- Radioactive stents represent a promising option for improving long-term outcomes in HC management.
