Abstract
Eighteen articles with 1641 revisional cases indicate that single anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S) is a safe and effective option for patients with failed primary procedures.
- BMI change after SADI-S was 11.01 kg/m² at 12 months, 9.57 kg/m² at 36 months, and 11.04 kg/m² at 60 months.
- Total weight loss after SADI-S was 23.78% at 12 months, 21.03% at 36 months, and 22.11% at 60 months.
- SADI-S was associated with remission rates of 69% for diabetes, 41% for hypertension, 47% for hyperlipidemia, and 69% for obstructive sleep apnea.
- Reported complications included leaks (2.9%), gastroesophageal reflux disease (5.1%), anemia (5.7%), diarrhea (8.7%), nutritional deficiency (4.2%), and steatorrhea (11.2%).
- In subgroup analysis, SADI-S, one anastomosis gastric bypass, and Roux-en-Y gastric bypass showed comparable outcomes in weight loss and resolution of obesity-related comorbidities.
