Single-Use Duodenoscopes Have Higher Environmental Cost Than Reusable Ones
A cradle-to-grave life cycle assessment finds reusable duodenoscopes may be the greener choice for ERCP procedures in Germany.
Summary
A new study published in Gut compared the environmental footprints of single-use versus reusable duodenoscopes used in a common bile duct procedure called ERCP. Using an ISO-compliant life cycle assessment methodology, researchers evaluated impacts across the full product lifespan — from manufacturing through disposal. The analysis, conducted in the German healthcare context, suggests that single-use scopes generate significantly greater environmental burdens than their reusable counterparts across multiple impact categories. This matters because hospitals are increasingly considering single-use endoscopes to reduce infection risks, but the environmental trade-offs are now under scrutiny. The findings have implications for procurement decisions in gastroenterology departments balancing patient safety with sustainability goals. Clinicians and hospital administrators should weigh both infection control benefits and ecological costs when choosing scope types.
Detailed Summary
As healthcare systems face mounting pressure to reduce their carbon footprints, the choice between single-use and reusable medical devices has become an urgent sustainability question. Endoscopic retrograde cholangiopancreatography (ERCP) is a complex gastrointestinal procedure that uses specialized instruments called duodenoscopes, which have historically been linked to difficult-to-eliminate infection risks — a key driver behind growing adoption of single-use alternatives.
This study, published in Gut, conducted a rigorous ISO-compliant cradle-to-grave life cycle assessment (LCA) comparing single-use and reusable duodenoscopes in the German healthcare context. The LCA methodology evaluates environmental impacts across the entire product lifespan: raw material extraction, manufacturing, transportation, clinical use, reprocessing where applicable, and final disposal.
The results indicate that single-use duodenoscopes carry a substantially higher environmental burden than reusable scopes across multiple impact categories, likely driven by the cumulative manufacturing and waste disposal demands of producing a new device for every procedure. Reusable scopes, despite requiring energy- and chemical-intensive reprocessing between uses, appear to offset these costs over their operational lifespan.
For clinicians and hospital procurement officers, these findings introduce a meaningful tension. Single-use scopes were embraced partly to address serious infection control failures associated with inadequate reprocessing of complex reusable scopes. This study does not negate those patient safety concerns but quantifies the ecological price attached to the single-use approach.
Several caveats apply. The study was funded by Ambu, a manufacturer of single-use endoscopes, which creates a potential conflict of interest despite claimed independent execution. The summary here is based solely on the abstract, and full methodology, numerical results, and sensitivity analyses are unavailable without access to the complete paper. Generalizability beyond the German healthcare infrastructure may also be limited.
Key Findings
- Single-use duodenoscopes have a larger environmental footprint than reusable scopes across multiple impact categories.
- The full product lifecycle — manufacturing to disposal — was assessed using ISO-compliant LCA methodology.
- Reusable scopes offset reprocessing costs environmentally when used across many procedures.
- The study was conducted in Germany, reflecting that country's specific energy grid and waste infrastructure.
- Findings create a direct tension between infection control benefits of single-use scopes and sustainability goals.
Methodology
The study used an ISO-compliant cradle-to-grave life cycle assessment, evaluating environmental impacts from raw material extraction through final disposal for both single-use and reusable duodenoscopes used in ERCP procedures in Germany. The LCA was independently executed by FORCE Technology and critically reviewed by Bureau Veritas per ISO 14071 standards.
Study Limitations
This summary is based on the abstract only, as the full paper is not open access; detailed results, sensitivity analyses, and numerical data are unavailable. The study was funded by Ambu, a single-use endoscope manufacturer, which introduces potential conflict of interest despite stated independent execution. Findings may not generalize beyond the German healthcare context due to differences in energy sources and waste management infrastructure.
