What this trial studies

This clinical trial aims to evaluate the safety and effectiveness of the Flexagon Self Forming Magnet Anastomosis system combined with OTOLoc for creating gastro-jejunal anastomoses in patients undergoing gastric surgery. It is a prospective, multi-center, single-arm study that will assess how well this innovative approach works in facilitating the surgical connection between the stomach and the jejunum. Participants will be monitored for outcomes related to the procedure's success and any potential complications.

Who should consider this trial

Good fit: Ideal candidates are adults aged 22 and older who are scheduled for gastric surgery requiring a gastro-jejunal or gastro-ileal anastomosis.

Not a fit: Patients with a BMI over 55 kg/m2 or uncontrolled diabetes may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to safer and more effective gastric surgeries with improved recovery times for patients.

How similar studies have performed: While this approach is innovative, similar studies using magnet-assisted techniques have shown promise, indicating potential for success.
