One-anastomosis gastric bypass (OAGB/MGB), a simplified bypass procedure with a single gastrojejunal anastomosis offering comparable weight loss to Roux-en-Y with reduced operative complexity. Widely performed in Chinese bariatric centers, this procedure creates a long narrow gastric pouch with a loop gastrojejunostomy, combining restriction with controlled malabsorption. Its technical simplicity results in shorter operative times and potentially fewer complications.
Pre-operative Evaluation
BMI and comorbidity assessment, upper endoscopy to rule out reflux esophagitis, metabolic panel, and multidisciplinary clearance
Duration: 2-3 daysPre-operative Diet
2-week low-calorie diet for liver volume reduction, protein supplementation, and baseline nutritional labs
Duration: 2 weeksLaparoscopic OAGB
Creation of long narrow gastric pouch (15-18cm), loop gastrojejunostomy at 200cm from ligament of Treitz, leak test
Duration: 1.5-2 hoursNutritional Program
Diet progression protocol, bile reflux monitoring, vitamin and mineral supplementation, and regular follow-up with weight and metabolic tracking
Duration: 12 months- Simpler single-anastomosis technique with shorter operative time
- Comparable weight loss to traditional gastric bypass (65-75% EWL)
- Easily reversible or revisable if needed
- Lower risk of internal hernia compared to Roux-en-Y
- Bile reflux into gastric pouch and esophagus
- Marginal ulcer at anastomosis site
- Nutritional deficiencies particularly iron and B12
- Potential need for revision if reflux becomes problematic
