Financial Impact

For each migration the patient must undergo a new intervention for additional stent placement. With typical ERCP interventions costing $4,649, this can end up costing the hospital significantly.

  • BOSTON SCIENTIFIC WALLFLEX Biliary RX Fully Covered Stent has reported up to 13% migration rate (n = 156)1
  • GORE® VIABIL® Biliary Endoprosthesis reported migrations ranging from 0 to 1.4%1

Migration as well as lack of patency require additional intervention, resulting in additional hospital stays and increased hospital costs.

Potential economic impact

If GORE® VIABIL® Biliary Endoprosthesis was used to treat 100 patients with unresectable malignant biliary strictures, your institution is estimated to annually:

Eliminate 16 reinterventions due to migrations and reduced patency, and save $116,716 versus using BOSTON SCIENTIFIC WALLFLEX Biliary RX Fully Covered Stent.

The average cost of a hospital inpatient ERCP with stent placement for patients without complications is approximately $4,649 (National healthcare payer database, 2015).
