Abstract
In a sample of 203 patients undergoing revisional one anastomosis gastric bypass, approximately 50% achieved excess weight loss greater than 50% at mid-term follow-up.
- Body mass index (BMI) at the time of revision for patients who had laparoscopic adjustable gastric banding was 41.3 kg/m² and for sleeve gastrectomy was 42 kg/m².
- Post-surgery, BMI reduced to 31.3 kg/m² for LAGB and 31.9 kg/m² for SG at mid-term follow-up.
- Resolution rates for type 2 diabetes were 93.3% in LAGB patients and 100% in SG patients, while hypertension resolution rates were 84.6% in LAGB and 100% in SG.
- Excess weight loss greater than 50% was associated with male gender, higher weight and BMI at the time of primary surgery, and higher BMI at revisional surgery.
- Independent predictors for achieving excess weight loss greater than 50% included male gender and higher BMI at the time of revisional surgery.
