Key result
In super-obese patients, duodenal switch resulted in a significantly greater percentage of excess body weight loss at 36 months compared to Roux-en-Y gastric bypass (68.9% vs. 54.9%; P<0.05).

May support duodenal switch in super-obese patients; extends observational data but leaves open need for randomized confirmation.

Absolute Event Rate: 68.9% vs 54.9%
p-value: p=< 0.05
In super-obese patients (BMI ≥50 kg/m²), duodenal switch provides superior long-term weight loss outcomes compared to Roux-en-Y gastric bypass with similar 30-day mortality.
Prachand et al. (2006) conducted a cohort in Super-obesity (n=350). Biliopancreatic diversion with duodenal switch (DS) vs. Roux-en-Y Gastric Bypass (RYGB) was evaluated on Percentage of excess body weight loss (% EBWL) at 36 months (p=< 0.05). In super-obese patients, duodenal switch resulted in a significantly greater percentage of excess body weight loss at 36 months compared to Roux-en-Y gastric bypass (68.9% vs. 54.9%; P<0.05).
