Gastric bypass combines excellent restriction with mild absorption. The restrictive component consists of a 20 to 30cc gastric pouch with a small, 1cm diameter distal outlet (exit) to Roux limb of jejunum as shown below. The length of the Roux Limb and the extent of the bypass (including the distal stomach, entire duodenum, and proximal jejunum) determine the degree of malabsorption.
- First, the surgeon creates a small gastric pouch (20 to 30 cc) which accounts for the restrictive component.
- The bilio-pancreatic limb is then fashioned by transection of the proximal small bowel 50 cm from the ligament of Treitz.
- A 75 to 150 cm length of jejunum (the alimentary limb) is brought up to the gastric pouch to carry food to the distal anastomosis.
Gastric bypass will not require adjustment, but patients need to commit to regular monitoring, lifelong six-monthly blood tests and daily multivitamin and mineral tablets. Patients can lose up to 70 percent of excess body weight with the gastric bypass procedure.
RYGB is considered the “gold standard” operation for morbid obesity and is the most common weight loss operation worldwide. Gastric bypass is usually performed by keyhole surgery, and the patient will need to stay in hospital for three days.
This operation helps weight loss by:
- Restricting the amount of food patients can eat by reducing the size of the stomach.
- Bypassing part of the stomach and intestine, reducing the amount of food the body is able to absorb.
It is particularly suitable for patients with type 2 diabetes.
Gastric Bypass FAQs
I had a bypass surgery and I am gaining weight now, can you help?
Yes, gastric band can be placed over the bypass. Professor Rasheed can place the band over a previously failed weight loss surgery with very good results. The objective is to place the band around the highest part of the stomach and restrict the ability to over-eat. Patients regain early satiety and fullness after eating which in turn results in weight loss.
You may be a candidate if you have had previous weight loss surgery if you had gastric bypass and the following:
- Loss of early satiety, ability to eat more and less restriction
- Weight gain after initial weight loss
- Unsatisfactory weight loss after initial surgery
