Distal Roux-en-Y gastric bypass results in greater long-term weight loss but carries higher risks of nutritional deficiencies.
- Mean BMI reduction after standard RYGB was 12.0 kg/m2 vs. 14.7 kg/m2 for distal RYGB, a significant difference of 2.7 kg/m2.
- Total weight loss percentage was 23.0% for standard vs. 28.2% for distal, a difference of 5.3% (p = 0.001).
- Higher rates of malnutrition (5 vs. 1), diarrhea (15 vs. 7), and vitamin D deficiency (32 vs. 24) in the distal group.
Consider patient selection carefully; distal RYGB may achieve better weight loss but with increased nutritional monitoring needs.
