What this trial studies

This study aims to measure the length of the small intestine during revisional bariatric surgeries, such as Roux-en-Y gastric bypass and Single Anastomosis Duodeno-ileal Sleeve, using a combination of 3D CT volumetry and pre-marked laparoscopic graspers. The approach seeks to mitigate the risks associated with traditional measurement methods, which can lead to intestinal injury. By utilizing advanced imaging techniques, the study hopes to provide more accurate assessments of bowel length, which is crucial for preventing malnutrition in patients post-surgery.

Who should consider this trial

Good fit: Ideal candidates for this study are patients who are scheduled for revisional bariatric surgery and are willing to consent to participate.

Not a fit: Patients with severe adhesions or those who refuse to participate or undergo a CT scan will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve surgical outcomes and reduce the risk of malnutrition in patients undergoing revisional bariatric surgery.

How similar studies have performed: While the use of 3D CT volumetry is gaining interest, this specific approach in revisional bariatric surgery is relatively novel and has not been extensively tested in prior studies.
