The Sleeve Gastrectomy
This operation is performed laparoscopically, using a keyhole technique. The surgeon makes five very small incisions over your abdomen (tummy) and inserts special instruments called trocars. Operating instruments can then be inserted to allow him to perform the operation.
​
The operation involves stapling off a around 85% of the stomach to construct a long and narrow tube that is calibrated (measured) onto a plastic tube so that it will be accurate.
​
This has the effect that you will eat less but you will feel full.
​
After the operation you will be carefully guided by the surgeon until you have settled and have adapted to you new small stomach. You will also be given a number to call if you have any problems, and will be given regular check ups for free to make sure you are doing well.
The Gastric Bypass
This operation is performed laparoscopically, using a keyhole technique. The surgeon makes five very small incisions over your abdomen (tummy) and inserts special instruments called trocars. Operating instruments can be inserted to allow him to perform the operation.
​
The operation involves stapling off a small part of the stomach to construct a small pouch that will serve as the new stomach. This is very small and is about the size of a small egg. The rest of the stomach is not removed but does not function anymore.
The small bowel is then divided and attached to the pouch so that the food that you eat will go from the small pouch to the distal part of the small intestine.
This has the effect that you will eat less but you will feel full.
The Mini Gastric Bypass
This operation is very similar to the gastric bypass. It is also also performed laparoscopically, using a keyhole technique. The surgeon makes five very small incisions over your abdomen (tummy) and inserts special instruments called trocars. Operating instruments can be inserted to allow him to perform the operation.
​
The operation involves stapling off a small part of the stomach to construct a small pouch that will serve as the new stomach. This is a little bit longer than the pouch described in the gastric bypass above. The rest of the stomach is not removed but does not function anymore.
The small bowel is then divided and attached to the pouch so that the food that you eat will go from the small pouch to the distal part of the small intestine. There is only one anastomosis (join up) between the stomach and the small bowel, unlike the gastric bypass as described above which has one between the stomach and the small bowel and another between the two sections of the small bowel lower down.

This has the effect that you will eat less but you will feel full.
