How Does One Anastomosis Gastric Bypass Work?
- Creating a narrow and longitudinal gastric pouch: A major part of the stomach is divided and stapled to create a small and long pouch. This has a much smaller curvature than gastric pouches created in traditional gastric bypass surgeries.
- Jejunal bypass: The newly created gastric pouch is connected with the lower portion of the small bowel just below the pouch, thereby bypassing the upper loop of the small bowel.
Comparison with Traditional Gastric Bypass
- OAGB is simpler than ROUX-en-Y and may have fewer risk of complications
- OAGB has shorter surgery and recovery time
- OAGB has lower chances of long-term complications such as acid reflux
- OAGB is a comparatively flexible weight loss procedure. It can be revised and reversed, which is not easily possible nor recommended for ROUX-en-Y patients
Benefits of One Anastomosis Gastric Bypass Surgery
- Significant weight loss
- Minimal complications
- Better management of obesity-related diseases including diabetes and hypertension
- Shorter recovery time: Quicker return to daily activities post-surgery.
- Reduced hunger: The surgery affects hunger hormones, leading to decreased appetite.
- Improved quality of life: Enhanced physical mobility and self-confidence post weight loss.
Potential Complications with OAGB Surgery
Short-term risks Include :
- Stomach leaks
- Excessive bleeding and blot clots
The long-term risks with mini gastric bypass include :
- Dumping syndrome
- Acid Reflux
- Nausea and vomiting
- Bile Reflux
Patients considering mini gastric bypass must keep in mind that this weight loss surgery is a restrictive and malabsorptive procedure, which results in reduced nutrient absorption, changes in the gut microbiome, and altered energy homeostasis. It may also involve making sustainable lifestyle changes, dependency on nutrients supplements, and regular follow-ups with your bariatric doctor.
