Using endoscopy to detect leaks after colorectal surgery

Routine Endoscopic Evaluation of Colorectal Anastomoses for Early Detection of Anastomotic Leakage (REAL-study)

Observational Amsterdam UMC, location VUmc · NCT06493565

This study is testing a new tool called LumenEye to see if it can help find leaks in the intestines early after colorectal surgery, especially for patients who may not show clear symptoms.

What this trial studies

This international observational study aims to implement a point-of-care digital rectoscope, LumenEye, to evaluate colorectal anastomoses for early detection of anastomotic leakage in patients who have undergone colorectal resection. The study focuses on patients with anastomoses located within 15 centimeters from the anorectal junction and seeks to diagnose leaks that may not present with obvious clinical symptoms. By conducting routine endoscopic evaluations in the early postoperative period, the study hopes to improve the timely diagnosis of anastomotic leakage, potentially preventing severe complications and improving patient outcomes.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older who have undergone sphincter-preserving colorectal surgery with anastomoses located within 15 centimeters from the anorectal junction.

Not a fit: Patients who are unable to assume the required positioning for anorectal endoscopic examination will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the incidence of severe complications associated with anastomotic leakage, leading to better recovery and quality of life for patients.

How similar studies have performed: Previous studies have shown that endoscopic evaluation can lead to the early detection of anastomotic leaks, indicating that this approach has potential based on prior findings.
