Exploring the role of gut bacteria in postoperative ileus after colorectal surgery

Evaluation of the Role of the Intestinal Microbiota in the Mechanism of Postoperative Ileum After Colorectal Surgery : a Preliminary Study

Observational University Hospital, Angers · NCT05512741

This study is trying to see if the bacteria in the gut affect the chances of developing a common problem called postoperative ileus after colorectal surgery.

What this trial studies

This observational study investigates the relationship between intestinal microbiota and the occurrence of postoperative ileus (POI) following laparoscopic colorectal surgery. By collecting fecal samples from patients, the study aims to identify potential microbial factors that contribute to the development and duration of POI. Understanding these factors could lead to new strategies for reducing the incidence of this common complication, which affects a significant percentage of patients undergoing colorectal surgery.

Who should consider this trial

Good fit: Ideal candidates for this study are patients undergoing laparoscopic colorectal resection with anastomosis and without a diverting stoma.

Not a fit: Patients with conditions that modify the microbiota or those experiencing postoperative complications may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to targeted interventions that reduce the occurrence and duration of postoperative ileus, improving recovery times for patients.

How similar studies have performed: While the role of intestinal microbiota in postoperative ileus is not well established, similar studies exploring gut bacteria's impact on other surgical outcomes have shown promising results.
