Biliopancreatic diversion with duodenal switch (BPD/DS) and its variants (SADI, TB) provide superior weight loss compared to Sleeve Gastrectomy (SG) and Roux-en-Y Gastric Bypass (RYGB) in extreme obesity, but at the cost of higher early complication rates and malnutrition risk.

For extreme obesity, malabsorptive surgeries like BPD/DS or SADI provide the best weight loss (38%+), significantly better than SG (23%) or RYGB (26%). However, these come with higher early complication rates (12.9% vs 4-8%). SG is safer but less effective for weight loss, making it a good option for older/younger patients or as a first step.

GoodQualifiesHIGH confidence
Notably, the 30-day complication rate was significantly higher in the BPD/DS group (12.9%) compared with the RYGB (4.7%) and SG (8.7%) groups... procedures with the greatest percentages of TWL were BPD/DS (38.4%), followed by RYGB (26.3%) and SG (23.6%)
