Gastric Bypass Procedure

£7000 / €7650

How does it work?

A small stomach pouch of about 15 ml is separated from the stomach and sealed with staples. With this technique the stomach and the small intestine are left intact! The small intestine is then cut 50 cm from the point at which it starts. The bottom part of the small intestine is then linked to the small stomach pouch. This can be done by means of staples or stitches.

The top part of the small intestine is then rejoined to the other part about 100 cm from the stomach.

The surgeon may decide to alter the length of these intestine segments.  As a result the stomach and duodenum are bypassed, so that food no longer passes through the stomach. The food does not mix with gastric, gall and pancreas juices until it reaches the point where the 2 small intestine loops meet each other.

The gastric bypass largely works through reduced food intake (restriction).

This is achieved in several ways:

·  Quick feeling of fullness: the small stomach pouch causes an early feeling of fullness, which inhibits the intake of food.

·  Reduced feeling of hunger: the feeling of hunger reduces appreciably. This can be explained by the fact that the stomach pouch is separated from the stomach, as a result of which less of the hunger hormone (ghrelin) is produced.

·  Dumping syndrome: this is an uncomfortable feeling, which is stimulated by the food in the small stomach pouch going directly to the small intestine. This feeling tends to be caused by eating sugars and by eating too quickly. Dumping stops a lot of patients from eating sweets, which is one of the reasons for weight gain after purely restrictive operations, such as gastric banding and gastroplasty. This dumping syndrome differs from patient to patient and appears to increase in the years after surgery
