Evaluating how intestinal gas affects recovery after abdominal surgery

Assessment of the Impact of Intestinal Gas Emission Quality on the Postoperative Course After Abdominal Surgery: Single-center Prospective Study - FLATQUAL- Abdominal Surgery and Gas Transit

University Hospital, Angers · NCT06675097

This study looks at how the type of gas produced in the intestines after abdominal surgery can help doctors understand recovery and any possible complications.

What this trial studies

This observational study aims to assess the relationship between the quality of intestinal gas emission and postoperative complications following abdominal surgery. It focuses on understanding how gas recovery can reflect intestinal transit and potentially indicate the presence of complications such as postoperative ileus. By analyzing the composition of intestinal gases, which may mirror the intestinal microbiota, the study seeks to correlate these factors with surgical outcomes. The findings could provide insights into improving postoperative care and recovery protocols.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who are scheduled for open or laparoscopic abdominal surgery with an expected hospital stay of at least two days.

Not a fit: Patients requiring a stoma, those needing immediate intensive care, or individuals unable to provide informed consent may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance postoperative recovery strategies and reduce complications for patients undergoing abdominal surgery.

How similar studies have performed: While the specific focus on intestinal gas quality is novel, related studies have indicated that microbiota analysis can predict postoperative complications.
