Abstract
Mean overall %TWL after conversion to RYGB was 13.2% for sleeve gastrectomy patients and 24.7% for adjustable gastric band patients.
- Forty-two patients underwent conversion from sleeve gastrectomy (SG) and 116 from adjustable gastric band (AGB) to Roux-en-Y gastric bypass (RYGB).
- Conversion from SG was primarily due to gastroesophageal reflux disease (GERD) in 57.1% of cases, while 77.6% of AGB conversions were due to weight regain.
- Mean pre-conversion Body Mass Index (BMI) was 36.7 kg/m for SG patients compared to 43.8 kg/m for AGB patients.
- At 30 days, complication rates were 9.5% for SG and 6% for AGB; however, at 2 years, rates increased to 31% for SG and 14.5% for AGB.
- Patients with AGB achieved significantly greater weight loss than those with SG at both 1 year and 2 years after conversion.
