Summary
Adding a ring to Roux-en-Y gastric bypass (RYGB) offers a modest mid-term weight loss advantage but increases vomiting and may require more reoperations. Long-term benefits are unclear, with no significant improvements in comorbidities or quality of life.
Area of Science:
- Bariatric Surgery
- Gastroenterology
- Metabolic Surgery
Background:
- The efficacy and safety of prophylactic ring augmentation in Roux-en-Y gastric bypass (RYGB) remain uncertain.
- Standard RYGB is a common bariatric procedure, but augmentation aims to enhance weight loss outcomes.
Conclusions:
- Ring augmentation provides a modest, temporary increase in excess weight loss for RYGB patients up to 3 years, without clear long-term advantages.
- The increased risk of vomiting and potential for higher reoperation rates must be considered.
- Current evidence does not support routine use; selective application should be based on expert opinion, not evidence-based recommendations, and weighed against potential harms.
