Microbiome in esophageal and stomach leaks

The Role the Microbiome Plays in Foregut Leaks: Understanding and Utilizing This Information to Improve Patient Outcomes

Not applicable Interventional Baylor Research Institute · NCT07424469

This project will test whether microbes in leaked fluid and nearby tissue from adults with esophageal or stomach leaks differ in ways that affect healing and complications.

What this trial studies

Investigators will collect infected fluid and tissue biopsy samples from adults who have an esophageal or stomach leak and compare the microbial composition and virulence within and between participants. They will analyze changes in the microbiota that occur with the leak and characterize host response mechanisms from the tissue samples. Comparisons of fluid versus tissue microbiomes will help define which microbial features are associated with worse outcomes or higher risk of postoperative leaks. The results aim to inform preventative approaches and improve patient management after foregut leaks.

Who should consider this trial

Good fit: Adults aged 18 or older with a diagnosed esophageal or stomach leak who can safely undergo biopsy and fluid sampling are ideal candidates.

Not a fit: People under 18, or adults who cannot safely tolerate biopsy procedures, and those without an esophageal or stomach leak are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, this work could identify microbial signatures or host responses that help prevent or better treat esophageal and stomach leaks.

How similar studies have performed: Prior work in colorectal anastomotic leaks has linked microbiome changes to poor healing and emerging data suggest a similar role in upper gastrointestinal leaks, but microbiome-guided treatments for foregut leaks remain largely untested.
