The restriction of the stomach also can be created using a silicone band, which can be adjusted by instillation or removal of saline through a port placed just under the skin. This operation can be performed laparoscopically, and is commonly referred to as a "lap band". Weight loss is predominantly due to the restriction of nutrients intake that is created by the small gastric pouch and few narrow outlet. It is considered one of the safest procedures performed today with a mortality rate of 0.05%.
A surgical weight loss procedure in which the stomach is reduced about 15% of its original size, by surgical removal of a large portion of the stomach, following the major curve. The open edges are the attached together (typically with surgical staples, sutures, or both) to leavethe stomach shaped more like a tube or a sleeves, with a banana shape. The procedures is performed laparoscopically and is not reversible.
Intragastric Balloon (Gastric balloon)
Placing a deflated balloon into the stomach and then filling it to decrease the amount of gastric space. The balloon can be left in the stomach for a maximum of 6 months and results in an average weight loss of 5-9 BMI over half a year.
It is a version of the more popular gastric sleeve or gastroectomy surgery where a sleeve is created by suturing rather than removing stomach tissue thus preserving its natural nutrient absorption capabilities.
