Comparing two surgical methods for treating severe obesity
Official title: Randomized Clinical Trial Comparing Two Surgical Techniques for the Treatment of Type III Obesity (BMI 40-50 kg/m2): Single Anastomosis Duodeno-ileal Bypass With Sleeve Gastrectomy (SADI-S) and Roux-en-Y Gastric Bypass (RY-GBP)
Run by Hospital Clinic of Barcelona · NCT06789965 · Data updated 2026-11-12
This study is testing two different weight loss surgeries for people with severe obesity to see which one helps them lose weight better and causes fewer problems afterward.

What this trial studies
This study compares two surgical techniques for treating Type III obesity, specifically Single Anastomosis Duodenoileal Bypass with Sleeve Gastrectomy (SADI-S) and Roux-en-Y Gastric Bypass (RY-GBP). Both methods aim to reduce stomach size and limit calorie absorption, but their effectiveness in postoperative weight control and complications will be analyzed. The study is crucial as obesity is a growing epidemic, and understanding the best surgical approach could significantly impact patient outcomes. Participants will be monitored for weight loss and any gastroesophageal issues following the procedures.
Why it matters
Potential benefit: If successful, this study could identify the more effective surgical technique for weight loss and improved health outcomes in patients with severe obesity.
How similar studies have gone: While both surgical techniques have been used in practice, there is limited comparative data on their effectiveness, making this study a novel approach.
