Procedure for stomach reduction
The desired weight reduction can be achieved by various methods. In some, the stomach itself is reduced in size (restrictive techniques), in other surgical techniques the stomach is bypassed in the digestive tract (bypass techniques). In the restrictive methods, the stomach is reduced in size by a so-called gastric band or similar methods.
Therefore, even after eating very small amounts of food, a feeling of fullness sets in and one automatically eats less. With these methods, digestion is less affected because all parts of the stomach are still present. However, it can still happen that you will not be able to keep your reduced weight as easily if you do not eat disciplined.
Liquid or mushy food can easily pass the reduced stomach and is fully digested, i.e. all calories are absorbed. This would be especially dangerous with ice cream, pudding and lemonades of all kinds. With the bypass methods the stomach is directly bypassed, i.e. the esophagus is separated from the stomach and directly sewn back on to the duodenum.
With this method the food is digested less and thus also less calories are taken in, thus the different bypasses belong to the malabsorptive (low or bad food intake) methods. The following is an overview of all the procedures for stomach reduction:
- Gastric band
- Gastroplasties
- Gastric Bypass
- Tubular Stomach
- Roux En Y Bypass
- Small bowel bypass
- Biliopancreatic Viversion
- Magenballoon
- Gastric pacemaker
A stomach reduction is a major surgical procedure that cannot be reversed. A distinction is made between gastric bypass and gastric tube surgery.
In a gastric tube resection, the majority of the stomach is removed, leaving only a small stomach tube. This procedure is technically less demanding than a gastric bypass and the pure operation time is about one hour. In addition, there is the preparation time and post-operative care after the operation.
In gastric bypass, food is transported past the stomach via a short circuit with the small intestine. Depending on how complicated the operation is, the duration of the procedure here is between two and five hours.After a gastric bypass, patients must remain in hospital for five to seven days. During this time, the patient recovers from the operation and slowly gets used to his reduced stomach and the associated change in diet.
