Unlike simple forward-viewing endoscopes such as gastroscope or colonoscope, duodenoscope houses much more complex design to fulfil its function. This design differences leave duodenoscopes more prone to contamination from inadequate disinfection process and potential dissemination of pathogens. Recent reports on dissemination of infection through the duodenoscope mandated an overhaul of duodenoscope utilization including development of a disposable duodenoscope. This article reviews the current state of disposable duodenoscope development, including reported early efficacy as well as its future direction and utilization.

Introduction: There are limited data comparing the contamination rates of reusable and novel duodenoscopes with disposable components. The clinical implications of novel duodenoscope bacterial contamination are also unknown. This study aimed to evaluate the rate of pathogenic bacterial contamination of novel and reusable duodenoscopes and assess the clinical implications for patients exposed to contaminated duodenoscopes.

Background And Aim: To reduce bacterial contamination after reprocessing, various new designs of duodenoscopes have been developed to better expose the elevator complex for cleaning. We compared the rates of bacterial contamination and organic residue in disposable distal cap duodenoscopes and detachable elevator duodenoscopes after manual cleaning and high-level disinfection (HLD), as well as their cost-effectiveness.
Methods: A total of 162 duodenoscopes were randomly assigned to either Group A (disposable distal caps; n = 81) or Group B (detachable elevator; n = 81).

Background: Healthcare systems contribute 5%-10% of the global carbon footprint. Given the detrimental impact of climate change on population health, health systems must seek to address this environmental responsibility. This is especially relevant in the modern era of minimally invasive procedures (MIP) where single-use instruments are increasingly popular.

Background: Infection outbreaks associated with contaminated reusable duodenoscopes (RUDs) have induced the development of novel single-use duodenoscopes (SUDs). This study aimed to analyze the material composition and life cycle assessment (LCA) of RUDs and SUDs to assess the sustainability of global and partial SUD implementation.
Methods: A single-center study evaluated material composition analysis and LCA of one RUD and two SUDs from different manufacturers (A/B).
