Comparative seven year outcomes of RYGB and SADI-S as revisional procedures for weight recurrence regain after sleeve gastrectomy: weight loss trajectory, reflux control, and metabolic safety

1

Obesity is a significant global health issue, with bariatric surgery being the most effective long-term treatment for severe obesity.
2

Roux-en-Y gastric bypass (RYGB) is the standard revisional procedure for patients with severe gastroesophageal reflux disease (GERD) after sleeve gastrectomy.
3

Single-anastomosis duodeno-ileal bypass (SADI-S) is gaining attention for its technical feasibility and metabolic benefits, but long-term data is limited.
4

Nutritional safety is a critical consideration in revisional surgery, as both RYGB and SADI-S have potential complications related to micronutrient deficiencies.
5

This study provides insights into the long-term outcomes of RYGB and SADI-S, supporting a more individualized approach to revisional bariatric surgery.
