What is it?
The gastric bypass can be the traditional Roux en Y gastric bypass or the Single anastomosis gastric bypass also know as Omega loop/ mini gastric bypass. The decision to choose one surgery over the other depends on various factors including presence of reflux, previous surgery etc. The Roux en Y gastric bypass has been around for a long time and has good data of long term outcomes as compared to the Mini gastric bypass.
A weight loss procedure that has been tried and tested for over 40 years. It’s a procedure where the stomach is partitioned to a smaller size and small bowel is re-routed to this new gastric pouch. In the banded gastric bypass a fixed silastic ring is placed around the gastric pouch.
- Long standing information and results
- 80 to 90% excess weight loss
- Up to 90% diabetes control
- Good control of reflux
- Risk of ulcer in the anastomosis
- Dumping syndrome
- Internal hernia risk
Gastric Bypass surgery is a procedure that involves partitioning the stomach into a smaller section (termed gastric pouch). A gastric bypass can reduce the volume of the stomach by up to 90%, reducing a typical ‘holding’ capacity of a 1000ml stomach to just 100ml. The small intestine is then divided and re-connected to this segment.
The result of this procedure is that feelings of satiety, or ‘feeling full’ occur after much less food is consumed by the patient as well as reduced absorption of ingested food.
This occurs because the smaller ‘segmented’ pouch ‘fills’ up much faster than the original stomach which stimulates nerves within the stomach wall and prompts the brain to ‘think’ the patient is in fact full after eating a significantly smaller portion of food.
As with most bariatric procedures, these are recommended for patients with a high BMI, typically over 40 (you can check your BMI here) but it is imperative you book a consultation with Mr Siva Gounder to determine what course of bariatric surgery is best suited to you.
