What this trial studies

This clinical trial investigates the effectiveness of the Single-Anastomosis Duodenoileal Switch (SADI-S) as a revisional surgery for patients who have experienced failure after sleeve gastrectomy. The study aims to compare this newer, simplified surgical technique with the standard duodenal switch procedure. By focusing on patients who meet specific criteria related to their previous weight loss surgery, the trial seeks to provide evidence on the safety and efficacy of SADI-S in managing obesity. The goal is to address the significant rates of failure associated with sleeve gastrectomy and improve patient outcomes.

Who should consider this trial

Good fit: Ideal candidates are individuals who had sleeve gastrectomy at least 18 months prior and still meet the NIH criteria for bariatric surgery.

Not a fit: Patients who are not eligible include those with a BMI below 35 kg/m2, pregnant individuals, or those with certain medical conditions like cirrhosis or inflammatory bowel disease.

Why it matters

Potential benefit: If successful, this approach could provide a safer and more effective surgical option for patients struggling with weight regain after sleeve gastrectomy.

How similar studies have performed: While there is limited prospective data on the SADI-S approach, similar studies on revisional bariatric surgeries have shown promising results.
