Hypothesis
Does gastric pouch resizing (GPR) after Roux-en-Y gastric bypass (RYGB) improve long-term weight loss and resolve comorbidities?
Conclusion
GPR is a safe procedure that stabilizes weight and resolves obesity-related comorbidities in well-selected patients.
Supporting Evidence
- 53% of patients had resolved obesity-associated comorbidities at follow-up.
- Mean BMI decreased from 39 kg/m2 before GPR to 35 kg/m2 after 5 years.
- Minor complications occurred in 12.5% of patients.
Takeaway
This study shows that resizing the stomach pouch can help people who gain weight back after surgery to lose weight again and feel better.
Methodology
Data from 48 patients who underwent GPR between 2016 and 2020 were analyzed, including follow-up surveys and weight measurements.
Potential Biases
Potential referral bias due to patients being referred by specialists.
Limitations
Heterogeneous preoperative workup results and inclusion of both distal and proximal RYGB patients.
Participant Demographics
39 (81.3%) female, mean age 46 ± 10 years.
