Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Several infectious outbreaks have been described in the literature as a result of contaminated endoscopes. These endoscopes cannot be sterilized and require an extensive cleaning process in which breaches of cleaning protocols, endoscope damage or the formation of biofilm can prevent proper disinfection. The risk of endoscopy associated infection (EAI) and colonization due to contaminated endoscopes is still considered to be low. However, it is likely that there is severe underreporting of outbreaks due to a lack of recognition or assuming an infection to be endogenous. Due to the sheer volume of upper-gastrointestinal endoscopy worldwide, even with a low risk of EAI, the number of affected patients is significant. In response, several manufacturers have turned to the production of single-use endoscopes that eliminate the risk of exogenous infections. There are single use duodenoscopes on the market that almost seem to match the performance of reusable duodenoscopes. A new single use sterile gastroscope, Ambu aScope gastro, has been developed whose performance has not been previously described in patients. This multicenter single arm consecutive case series study will test the performance of these single use gastroscopes in patients undergoing esophagogastroduodenoscopy.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Esophagogastroduodenoscopy (EGD) is an important tool in the diagnosis and treatment of upper gastrointestinal-disorders. It has broad range of indications including dysphagia, gastroesophageal reflux disease, esophageal strictures or upper gastrointestinal (GI) bleeding. It is a common procedure and is performed around 6.1 million times annually in the United States. However, performing endoscopy is not without risk and complications of EGD include perforation, bleeding, aspiration, and infection.

Endoscopy associated infection (EAI) can be endogenous, due to translocation of the patient's own microbial gut flora into the bloodstream, or exogenous as a result of contaminated equipment. The latter receives increased attention as several outbreaks have been reported past decades. Endoscopes cannot be sterilized and require an extensive cleaning process in which breaches of cleaning protocols, endoscope damage or the formation of biofilm can prevent proper disinfection. Many of the published outbreaks involved contaminated duodenoscopes. However, multiple outbreaks due to a contaminated gastroscopes have also been described. The prevalence of contaminated ready-to-use gastroscopes has rarely been studied. One study reported the contamination of ready-to-use gastroscopes to be 64% post-high-level disinfection (HLD), which went down to 9% post-storage.

It is probable that EAI's are underreported due to a lack of recognition of EAI's caused by sensitive microorganisms, sparse microbiological surveillance post-endoscopy or the possibly long duration between the endoscopy and the development of the infection. However, even if the risk of EAI is low, due to the large numbers of endoscopies performed worldwide the number of affected patients is significant.

Single use endoscopes would completely eliminate the risk of exogenous EAI's. Already multiple single-use duodenoscopes have been brought to the market whose performance seems be comparable to reusable duodenoscopes. To address the risk of contaminated gastroscopes, Ambu is a company who produced a single-use gastroscope, the Ambu® aScope™ gastro. It is a lightweight scope equipped with two LED lights for optimal illumination and a high-resolution digital camera. The aScope gastro has recently been CE-approved, but no studies about its performance in patients have been published
