Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are adults aged 18-85 who are scheduled to undergo esophagogastroduodenoscopy.
✕Probably not a fit
Patients who are not undergoing endoscopy procedures will not benefit from this study.

What this trial studies
This study evaluates a novel capillary endoscopy aspiration catheter designed to improve the efficiency of fluid collection from the small intestine during endoscopy procedures. The research compares the performance of this new catheter against the conventional aspiration catheter in terms of suction speed and volume of fluid collected. A total of 46 patients undergoing esophagogastroduodenoscopy at Cedars-Sinai Medical Center will participate, with each patient providing fluid samples using one of the two catheters. The goal is to determine if the capillary catheter can enhance the process of microbiota assessment in the small intestine.
Why it matters
Potential benefit: If successful, this new catheter could lead to more efficient and less contaminated fluid collection during endoscopic procedures, improving microbiome research and patient outcomes.
How similar studies have gone: While the conventional aspiration catheter is FDA-approved, the capillary catheter is a novel approach that has not been previously tested in this context.
