Percutaneous placement of 12-mm metallic biliary stents in patients with malignant extrahepatic biliary obstruction: Outcomes of expanded polytetrafluoroethylene-covered stents versus uncovered stents
Purpose
To investigate the outcomes of percutaneous placement of 12-mm metallic biliary stents in patients with malignant extrahepatic biliary obstruction and to compare the outcomes of covered stents with those of uncovered stents.
Methods
From May 2020 to February 2022, 49 consecutive patients who underwent placement of 12-mm-diameter expanded polytetrafluoroethylene (ePTFE) covered stents were retrospectively studied. The data from these patients were compared with data from 48 consecutive patients who underwent 12-mm-diameter uncovered stent placement between December 2018 and April 2020.
Results
There were no significant differences in technical success (p > 0.999), successful internal drainage (p > 0.999), adverse events (p = 0.774), and patient survival (p = 0.084) between the two groups. Adverse events occurred in eight (16.3 %) patients in the covered stent group and six (12.5 %) in the uncovered stent group. Cumulative stent patency rate was significantly higher in the covered stent group than in the uncovered stent group (p = 0.015), with cumulative patency rate at 6 months being 97.8 % in the covered stent group and 80.8 % in the uncovered stent group. Stent occlusion occurred in 3 (6.4 %) of 47 patients in the covered stent group and 15 (33.3 %) of 45 patients (41 %) in the uncovered stent group, with this difference being significant (p = 0.001).
Conclusion
Percutaneous placement of 12-mm-diameter metallic biliary stents is effective and safe in patients with malignant extrahepatic biliary obstruction. Moreover, ePTFE covered stents were significantly superior to uncovered stents in terms of stent patency.
