What this trial studies

This study compares the performance of Symmcora® mid-term suture and Novosyn® conventional suture in patients undergoing robotic-assisted gastric bypass surgery. It is a prospective, mono-centric, randomized, and patient-blinded trial where participants will be allocated to one of the two suture groups for the gastro-jejunal and jejuno-jejunal anastomoses. The goal is to evaluate the effectiveness and outcomes of these sutures in routine clinical practice.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with a BMI of 35 or higher and related comorbidities, undergoing elective robotic-assisted gastric bypass surgery.

Not a fit: Patients who are undergoing emergency surgery or have a history of previous gastric surgery may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve surgical outcomes and recovery for patients undergoing gastric bypass surgery.

How similar studies have performed: Other studies have shown promising results with similar approaches in surgical suturing techniques, indicating potential for success.
