Treatment Options
Obesity Surgery
:: Laparoscopic Adjustable Gastric Banding :: Tube Gastrectomy
:: Gastric Bypass
Gastric Roux-En-Y Bypass
Here a small stomach pouch is created to restrict food intake.
Next, a Y-shaped section of the small intestine is attached to the
pouch to allow food to bypass the lower stomach, the duodenum (the
first segment of the small intestine), and the first portion of
the jejunum (the second segment of the small intestine). This
bypass reduces the absorption of nutrients and thereby reduces the
calorie intake.
Advantages:
- "Dumping syndrome" if sweets and chocolates taken
- Good operation for sweet eaters
- Long track record
- Tend to lose a little more weight than gastric band
Disadvantages:
- Open surgery therefore increased risks
- Longer recovery time
- Permanent
- Not reversible
- Staple line leak
- Minor late weight regain 10-20% after 2-5 yrs
- Nutritional/ mineral supplements required
Residual stomach capacity: 30-50mls
Estimated weight loss: 60-70% EWL over 2 years.
