Summary
Gianturco-Rosch expandable metallic stents showed limited long-term patency in malignant disease, averaging 7 months. While not advantageous overall, these stents may benefit select patients with benign biliary conditions.
Area of Science:
- Gastroenterology and Hepatology
- Interventional Radiology
Background:
- Gianturco-Rosch expandable metallic stents are used for biliary drainage.
- Long-term outcomes data for these stents are limited.
Purpose of the Study:
- To report long-term follow-up results for patients treated with Gianturco-Rosch expandable metallic stents.
- To evaluate the efficacy and durability of these stents in malignant and benign biliary obstructions.
Main Methods:
- Retrospective analysis of nine patients who received Gianturco-Rosch expandable metallic stents.
- Assessment of stent patency duration and clinical outcomes.
Main Results:
- Average stent patency was 7 months in a cohort of nine patients, seven with malignant disease.
- One patient with inactive primary sclerosing cholangitis (PSC) maintained patency for 22 months.
- Recurrent stent occlusion occurred in a second PSC patient, indicating variable outcomes.
Conclusions:
- Gianturco-Rosch expandable metallic stents did not demonstrate overall advantages in the studied patient population.
- These metallic stents may have a potential application in managing specific cases of benign biliary disease.
- Further investigation is warranted to define the role of these stents in non-malignant biliary strictures.
