Summary
Palliative biliary drainage using metallic stents or plastic tubes is effective for malignant biliary obstruction. Treating the local tumor after stenting can improve stent patency and patient survival.
Area of Science:
- Interventional Radiology
- Gastroenterology
- Oncology
Background:
- Malignant biliary obstruction presents a significant challenge in palliative care.
- Effective drainage methods are crucial for improving patient quality of life.
Purpose of the Study:
- To evaluate the efficacy of palliative drainage using metallic indwelling stents or plastic tubes.
- To assess complications, stent patency, and patient survival rates.
Main Methods:
- A total of 243 patients with malignant biliary obstruction underwent transhepatic placement of metallic stents and/or plastic tubes.
- Patient data, including procedure details, complications, survival, and stent patency, were collected and analyzed.
- Kaplan-Meier survival analysis was used to calculate survival and patency rates.
Main Results:
- The 2-month mortality rate was 8.64%, with major complications occurring in 0.8% of patients.
- Average initial stent patency was 7.5 months, and average survival was 9 months.
- Patients treated for local tumors after stenting demonstrated improved survival (11.3 months) and stent patency (9.7 months).
Conclusions:
- Percutaneous transhepatic bile drainage with stents is a well-tolerated palliative procedure.
- Adjuvant treatment for local tumors following stenting can significantly enhance stent patency and prolong patient survival.
