Laparoscopic Gastric Banding

This operation is performed using a key hole technique making five small cuts, it is performed under general anaesthetic, and usually only requires a day case admission.

This is a restrictive procedure where a 'band' is placed around the top of the stomach to create a small pouch where food enters. Food then exits this pouch slowly through a small passageway left by the band and passes into the larger part of the stomach and digestion continues on as it would normally.

 As the top stomach pouch is only very small, it gets filled up quickly, giving you a feeling of fullness very quickly, and therefore reduces the amount you eat, helping you to lose weight.

 You might expect to lose an average of 40-50% excess weight. 

Laparoscopic Sleeve Gastrectomy

This operation is performed using a key hole technique making five small cuts, it is performed under general anaesthetic, and requires a hospital stay of usually two nights.A Sleeve Gastrectomy is an operation that reduces the size of the stomach by around 75%. It reduces a person's appetite and the amount of food they can eat, and therefore results in weight loss.

The operation involves part of the stomach being removed, leaving a smaller stomach in the shape of a 'sleeve'. Food will leave the stomach as normal through the pyloric valve at the bottom of the stomach and go into the small intestine. Therefore, although the stomach is smaller, the way it works remains unchanged.

Sleeve Gastrectomy can be considered as surgery for weight loss in two stages. An initial Sleeve Gastrectomy, followed at a later date by either a Gastric Bypass or by a Duodenal Switch.

Gastric Bypass and Duodenal Switch are both complex operations, and where super obese patients have severe weight related complications, these complex operations may be too risky to proceed with, therefore a Sleeve Gastrectomy is considered as an initial treatment. You might expect to lose an average of 60-70% excess body weight. 

Laparoscopic Gastric bypass

A small pouch (about the size of an egg) where food enters is made at the top of the stomach. This pouch is detached from the larger, bottom part of the stomach. Part of the small intestine is then divided, and the bottom end is pulled up and attached to the small pouch, food goes into the small pouch and then straight into the small intestine.

The larger part of the stomach is still attached to the top part of the small intestine and the rest of the small intestine, allowing gastric juice to be drained through the gastro-intestinal system.It works by reducing the amount of food you eat. The small pouch gets full quickly, making you feel full earlier. There is also a degree of malabsorption that occurs after the gastric bypass, as the food you eat bypasses the first part of the small intestine. You might expect to lose an average of 70-75% excess body weight.
